Neuropsychological development of large for gestational age infants at the age of 12 months / 中国当代儿科杂志

OBJECTIVES@#To investigate the level of neuropsychological development in large for gestational age (LGA) infants at the age of 12 months.@*METHODS@#The infants, aged 12 to <13 months, who attended the Outpatient Service of Child Care in the First Affiliated Hospital of Shandong First Medical University from December 2021 to June 2023, were enrolled as subjects. According to the gestational age and birth weight, they were divided into preterm appropriate for gestational age (AGA) group, preterm LGA group, early term AGA group, early term LGA group, full-term AGA group, and full-term LGA group. A modified Poisson regression analysis was used to investigate the association between LGA and neuropsychological development outcome at 12 months of age.@*RESULTS@#After adjustment for confounding factors, compared with the full-term AGA group at the age of 12 months, the full-term LGA group had a significant increase in the risk of language deficit (RR=1.364, 95%CI: 1.063-1.750), the early term LGA group had significant increases in the risk of abnormal gross motor, fine motor, language, and the preterm LGA group had significant increases in the risk of abnormal language, social behavior, and total developmental quotient (P<0.05); also, the early term AGA group had higher risks of developmental delay across all five attributes and in total developmental quotient at the age of 12 months (P<0.05); except for the language attribute, the preterm AGA group had higher risks of developmental delay in the other 4 attributes (P<0.05).@*CONCLUSIONS@#The neuropsychological development of LGA infants with different gestational ages lags behind that of full-term AGA infants at 12 months of age, and follow-up and early intervention of such infants should be taken seriously in clinical practice.

Clinical significance of alveolar-arterial oxygen gradients for late preterm and full-term infants with acute respiratory distress syndrome / 中国新生儿科杂志

Objective:To study the clinical significance of alveolar-arterial oxygen gradients (P A-aO 2) for late preterm and full-term infants with acute respiratory distress syndrome (ARDS). Methods:From January 2020 to June 2022, infants (gestational age ≥34 weeks) diagnosed with ARDS were admitted to the Neonatology Department of our hospital. The infants were assigned into the invasive group and the non-invasive group according to the ventilation mode. The infants with the same gestational age and diagnosed with neonatal wet lung were assigned into the control group. P A-aO 2 levels within 1 h after birth were compared among the three groups. The correlation of P A-aO 2 with ARDS, ventilation mode and duration were studied. Receiver operating characteristic (ROC) curve was used to determine the predictive value of P A-aO 2 within 1 h after birth for ARDS and the need of invasive ventilation. Results:A total of 36 cases were enrolled in the invasive group, 19 cases in the non-invasive group and 50 cases in the control group. Within 1 h after birth, P A-aO 2 in the invasive group was significantly higher than the non-invasive group and the control group ( P<0.05), and the non-invasive group higher than the control group ( P<0.05). Correlation analysis showed that P A-aO 2 within 1 h after birth in the invasive group was positively correlated with the duration of invasive ventilation and total mechanical ventilation ( r=0.601, P<0.001; r=0.504, P=0.002); P A-aO 2 before successful withdrawal of invasive ventilation was not correlated with subsequent non-invasive ventilation duration; and no correlation existed between P A-aO 2 within 1 h after birth and the duration of non-invasive ventilation in the non-invasive group. The area under the ROC curve for P A-aO 2 within 1 h after birth to predict ARDS was 0.875, with a sensitivity of 87.3% and a specificity of 72.0% at a cutoff value of 50.0 mmHg. The area under the ROC curve for predicting the need for invasive ventilation in infants with ARDS was 0.851, with a sensitivity of 80.0% at a cutoff value of 73.3 mmHg and a specificity of 75.0%. Conclusions:Late preterm and full-term infants have a higher risk of ARDS at P A-aO 2>50.0 mmHg within 1 h after birth. Infants with ARDS are more likely to require invasive ventilation if P A-aO 2>73.3 mmHg. The higher the level of P A-aO 2, the longer the duration of invasive ventilation and total duration of mechanical ventilation.

Por que devemos nos preocupar com os bebês a termo internados em uma unidade de terapia intensiva neonatal / Por qué deberíamos preocuparnos por los bebés nacidos a término ingresados en una unidad de cuidados intensivos neonatal / Why we should care about full-term infants admitted to a neonatal intensive care unit

RESUMO O objetivo deste estudo foi analisar a razão pela qual devemos nos preocuparmos com os bebês a termo internados em uma unidade de terapia intensiva neonatal. Trata-se de estudo documental, descritivo e retrospectivo de 262 recém-nascidos (RNs) a termo. As variáveis utilizadas foram: características dos RN; diagnóstico principal, tempo de permanência e acompanhamento pela equipe multiprofissional; e encaminhamento pós-alta. Houve prevalência do sexo masculino (52%), de Apgar 9 no 5º minuto e da raça/cor branca do RN e da mãe (61,1% e 48,9%, respectivamente). O diagnóstico principal foi a disfunção respiratória (28,8%), e o tempo de permanência foi de oito dias. Houve diferença significativa entre os tempos de permanência (p=0,013), em que as doenças cardiorrespiratórias e outras doenças levaram a um menor tempo de internação em relação à má formação ou às doenças maternas. O serviço social foi o mais procurado para o acompanhamento (81,2%) e a fisioterapia, o menos buscado (18%). RNs com maior peso ficaram menos tempo internados, e os acompanhados por fisioterapia apresentaram tempo de permanência mais elevados (p<0,001). O principal desfecho foi a alta hospitalar (68,7%) e encaminhamentos para a Unidade Básica de Saúde (57%). Os achados deste estudo apontam a presença de bebês menos graves, baixo número de estudos específicos para a população a termo e outros diagnósticos que nos remetem a cuidados não intensivos.

Se trata de un estudio documental, descriptivo y retrospectivo, realizado con 262 recién nacidos (RN) a término. Las variables utilizadas fueron: características de los RN; diagnóstico principal, tiempo de estancia y seguimiento por el equipo multidisciplinar; y derivación posterior al alta. Hubo predominio del sexo masculino (52%), Apgar 9 al 5º minuto y raza/color blanca del RN y de la madre (61,1% y 48,9%, respectivamente). El principal diagnóstico fue disfunción respiratoria (28,8%), y la estancia hospitalaria fue de ocho días. Hubo una diferencia significativa entre el tiempo de estancia (p=0,013), en que las enfermedades cardiorrespiratorias y otras enfermedades resultaron en una menor estancia hospitalaria con relación a malformaciones o enfermedades maternas. El trabajo social fue el más buscado para el seguimiento (81,2%), y la fisioterapia, el menos buscado (18%). Los RN con mayor peso tuvieron una menor estancia hospitalaria, y aquellos que recibían seguimiento de fisioterapia tuvieron mayor tiempo de estancia (p<0,001). El principal desenlace fue el alta hospitalaria (68,7%) y las derivaciones a la Unidad Básica de Salud (57%). Los hallazgos de este estudio apuntan a la presencia de recién nacidos menos graves, un bajo número de estudios específicos para la población a término y otros diagnósticos que nos remiten a cuidados no intensivos.

ABSTRACT This study aims to analyze why we should care about full-term newborns admitted to a neonatal intensive care unit. This is a documented, descriptive, and retrospective study of 262 full-term newborns. Variables used: newborns' characteristics; main diagnosis, length of stay, follow-up by a multidisciplinary team; post-discharge referral. Most newborns were boys (52%), had a 5-minute Apgar score of nine, and most newborns and their mothers were white (61.1% and 48.9% respectively). Respiratory dysfunction was the main diagnosis (28.8%). Length of stay was eight days. There was a significant difference regarding length of stay (p=0.013), in which those with cardiorespiratory and other diseases stayed less time compared to those with malformation or maternal diseases. The social service was the most sought (81.2%) service, whereas physical therapy the least sought (18%). Newborns with higher weight were hospitalized for less time. Those that underwent physical therapy had longer stay (p<0.001). Main outcome was hospital discharge (68.7%) and referrals to the Basic Health Unit (57%). This study outcomes indicated newborns with less severe conditions, low number of specific studies for the full-term population, other diagnoses that refer to non-intensive care.

Study on colonization of Group B Streptococcus in pregnant women of Mongolian and Han nationality and the status of neonatal early-onset septicemia / 中华急诊医学杂志

Objective:To explore the carrier status of group B streptococci (GBS) in pregnant women of Mongolian and Han nationality and the neonatal GBS infection in order to identify the high risk factors of GBS infection in Mongolian and Han newborns in this area.Methods:Totally 7289 pregnant women and their newborns born alive were tested for GBS in the Affiliated Hospital of Inner Mongolia Medical University from June 2017 to June 2020, and their newborns were cultured for GBS, and the venous blood of newborns delivered by GBS positive women were detected for anti-GBS capsular polysaccharide antibody level, in order to determine the high risk factors of neonatal GBS infection.Results:Among the 7289 pregnant women, 3136 were Mongolian pregnant women (2599 full-term delivery and 537 premature delivery) and 4153 were Han pregnant women (3541 full-term delivery and 612 premature delivery). The results of GBS test showed that the GBS carrier rate was 8.19% in the Mongolian preterm delivery group, 4.35% in the Mongolian term group, 11.93% in the Han preterm group, and 5.76% in the Han term group, indicating that the carrier rate of GBS in the preterm group was significantly higher than that in the term group, regardless of Mongolian and Han nationality ( P < 0.05). Further comparing the GBS carrier rate of Mongolian and Han pregnant women, the GBS carrier rate of Mongolian pregnant women was significantly lower than that of Han pregnant women regardless of the premature delivery group and term group ( P < 0.05). (2) A total of 434 newborns were born by GBS positive parturients. The positive rates of GBS in Mongolian premature infants, Mongolian full-term infants, Han premature infants and Han full-term infants were 29.55%, 14.16%, 31.51% and 17.65%, respectively, suggesting that the positive rate of GBS in premature infants was significantly higher than that in full-term infants, regardless of Mongolian and Han nationality ( P<0.05). Further comparing the positive rate of GBS in Mongolian and Han newborns, there was no significant difference in the positive rate of GBS between Mongolian newborns and Han newborns, no matter the premature delivery group and the full-term group. (3) This study compared the incidence of early-onset GBS septicemia in Mongolian and Han newborns. The results showed that the incidence of early-onset GBS septicemia in Mongolian premature infants was 23.08%, and none in full-term infants. The incidence of early-onset GBS septicemia in Han premature infants was 26.09%. The incidence of early-onset GBS septicemia in term infants was 5.56%. The incidence of neonatal GBS septicemia in the preterm group was significantly higher than that in the term group, regardless of Mongolian and Han nationality. By further comparing the incidence of GBS septicemia in Mongolian and Han newborns, there was no significant difference in the positive rate of GBS between Mongolian newborns and Han newborns regardless of the premature delivery group and the term group. (4) In both Mongolian and Han nationality, the level of anti-GBS capsular polysaccharide antibody in premature infants was significantly lower than that in term infants ( P < 0.05). (5) Regardless of the Mongolian and Han nationality, compared with GBS negative group, GBS positive rate was higher in pregnant women aged≥35 years old, with history of menstruation, miscarriage, vaginitis, floating population, and those who had not undergone pre-pregnancy examination,,which were the high risk factors for GBS-positive pregnant women during pregnancy. (6) In both Mongolian and Han nationality, the incidence of chorioamnionitis, puerperal infection, premature delivery and premature rupture of membranes in the GBS positive group was higher than that in the GBS negative group, and the incidence of fetal distress and neonatal asphyxia in the GBS positive group was also higher than that in the GBS negative group. Conclusions:The carrier rate of GBS in Mongolian pregnant women is lower than that in Han pregnant women, and positive GBS during pregnancy will increase the incidence of adverse maternal and fetal outcomes such as chorioamnionitis, puerperal infection, premature delivery, premature rupture of membranes, fetal distress, neonatal asphyxia and neonatal early-onset GBS septicemia. The high risk factors are maternal age ≥ 35 years old, history of menstruation, abortion, vaginitis, floating population, and infection without pre-pregnancy examination. We should attach great importance to the perinatal high risk factors and formulate corresponding intervention measures accordingly, and make rational use of antibiotics for prenatal prevention, so as to further reduce the incidence of early-onset GBS septicemia in newborns.

Investigation on the IGF-1 and lipid level in term small for gestational age infants within 24 hours postnatally / 中国新生儿科杂志

Objective:To study the insulin-like growth factors-1 (IGF-1) and lipid level of term small for gestational age (SGA) infants within 24 hours postnatally and to explore the correlation between IGF-1 and blood lipids.Methods:A prospective study was conducted on singleton term SGA and appropriate for gestational age infant (AGA) who were delivered and admitted to the neonatal ward of Guangdong Women and Children Hospital within 24 hours after birth from May 2020 to January 2021, and the infants were divided into SGA and AGA groups to compare the differences in IGF-1 and lipid levels within 24 hours after birth and to analyze the correlation between IGF-1 and lipids.Results:A total of 95 cases in the SGA group and 84 cases in the AGA group were included in the study. The proportion of infants with IGF-1 <25 ng/ml was significantly higher in SGA group (87.4%) than in the AGA group (52.4%). It was also found that the proportion of infants with IGF-1 <25 ng/ml in SGA was significantly higher than that in AGA within different gender composition groups, early-term and full-term births groups. The triglyceride (TG) level was higher in the SGA group than that in the AGA group, but the high-density lipoprotein cholesterol (HDL-C) level was lower than that in the AGA group ( P<0.05). IGF-1 level within 24 hours postnatally in SGA and AGA was positively correlated with HDL-C levels ( P<0.01) and negatively correlated with TG ( P<0.01), and HDL-C level was a predictor of IGF-1. Conclusions:Compared with term AGA, SGA term infants showed insufficient IGF-1 and HDL-C secretion and high TG within 24 hours after birth. Nutritional support for SGA should be given promptly after birth to avoid hypoglycemia and to stimulate IGF-1 secretion.

Through the application of the best evidence, it is beneficial to improve the outcome of pregnant women in the neonatal perinatal period, standardize the process of inducing labor with oxytocin, and improve the quality of obstetric care.

Fatores materno-infantis associados ao desenvolvimento de bebês prematuros e a termo / Maternal-infant factors associated to the development of preterm and full-term babies / Factores materno-infantiles asociados al desarrollo de bebés prematuros y a término

Conhecer a influência de variáveis materno-infantis e ambientais no processo desenvolvimental torna possível que atrasos sejam minimizados. Pretendeu-se comparar variáveis sociodemográficas e de desenvolvimento de bebês prematuros e a termo aos três meses de idade e identificar as influências de fatores materno-infantis associadas ao desenvolvimento destes bebês. Participaram 275 díades mãe-bebê, sendo 168 prematuros e 107 a termo. Aplicou-se uma entrevista para coleta das variáveis materno-infantis e as Escalas Bayley III para avaliar o desenvolvimento. Os resultados indicaram que há diferenças significativas entre a termo e prematuros em relação à escolaridade materna, presença de irmãos e não planejamento materno da gravidez. Prematuros apresentaram maiores atrasos no desenvolvimento cognitivo, em linguagem expressiva, motor fino e motor amplo. A identificação de atrasos aos três meses apontou para a importância de programas de estimulação precoce como fator de proteção para evitar atrasos no desenvolvimento e como orientação aos cuidadores primários do bebê.

Knowing the influence of maternal-infant and environmental factors in the developmental process makes it possible to minimize delays. We intended to compare socio-demographic and developmental variables of preterm and full-term babies at three months of age, and to identify the influences of maternal-infant factors associated with the development of these babies. Participants were 275 mother-baby dyads, 168 being preterm and 107 full-term babies. We applied an interview to collect maternal-infant variables and we used the Bayley III Scales to evaluate development. The results indicated that there are significant differences between full-term and preterm babies regarding maternal education, the presence of siblings, and lack of maternal pregnancy planning. Preterm babies displayed more delays in cognitive development, expressive language, fine and gross motor development. The identification of delays at three months pointed to the importance of early stimulation programs as a protective factor to avoid developmental delays and as guidance to the primary caregivers of the baby.

Los prematuros presentaron mayores atrasos en el desarrollo cognitivo, en lenguaje expresivo, control motor fino y grueso. La identificación de atrasos a los tres meses mostró la importancia de programas de estimulación temprana como factor de protección para evitar atrasos del desarrollo y como orientación a los cuidadores primarios del bebé.

Efficacy and safety of prostaglandins vs double balloon catheter in inducing labor: a meta-analysis

Background: To compare the efficacy and safety of double‐balloon catheter with prostaglandin E2 (PGE2) in induction of labor.Methods: We searched electronic sources from Medline, Scopus, PubMed, Science Direct and Cochrane Library Database of Systematic Reviews. Only randomized controlled trials and observational studies comparing the PGE2 agents with double-balloon catheter for cervical ripening and labour induction in women with unfavorable cervix were included in the analysis. The main outcomes included vaginal delivery rate within 24 hours and cesarean delivery rates. We calculated relative risks and mean differences using fixed effects and random‐effects models.Results: Prostaglandin was more favourable for vaginal delivery within 24 hours compared to double balloon catheter, but was not statistically significant (RR 1.17: 95% CI 0.96-1.42 p =0.12). The induction to delivery time yielded a non-significant result that again favors prostaglandin (SMD 0.02 CI:0.18,0.22, p = 0.86). There was no significant difference in the cesarean delivery rates between the two groups (RR 1.02: 95% CI 0.92-1.14, p = 0.68). Uterine hyperstimulation and Neonatal Intensive Care Unit (NICU) admissions were significantly higher with prostaglandin. (RR 0.09: CI 0.04, 0.22 p<0.00001 and RR 0.75 CI: 0.62,0.90 p=003).Conclusions: There is no significant difference in the success of induction of labour between use of PGE2 and double balloon catheter. Uterine hyperstimulation and NICU admissions were significantly higher in Prostaglandin group.

Study on risk factors of respiratory distress syndrome in term neonates: a retrospective case-control study

Background: Respiratory distress syndrome (RDS) is one of the most common causes of neonatal respiratory failure and neonatal death. It is more common in preterm neonates but also been found in term and late preterm neonates. This study aims at studying the risk' factors for developing RDS in term neonates. Objectives was to study the maternal and perinatal risk factors for RDS in term neonates.Methods: This is a retrospective case control study conducted in neonatal intensive care unit of tertiary care centre. A total of 100 term neonates with RDS were taken as cases and 150 normal term neonates were taken as control. Data were collected from the hospital NICU records, maternal and neonatal history was taken. The ?2 tests or Fisher's exact text were used for one-way risk factor analysis. The effects of multiple factors on term neonatal RDS were analyzed using logistic regression analysis.Results: In our study RDS in term neonates' was significantly associated with following risk factors like selective cesarean section, male sex, SGA, oligohydramnios, MSAF, severe fetal distress, birth asphyxia, PROM, and maternal-fetal infection. Among the significant risk factors severe birth asphyxia, maternal-fetal infection, PROM, MSAF were showing positive association with RDS in full-term neonates.Conclusions: Several high-risk factors such as severe birth asphyxia, maternal-fetal infection, PROM, and MSAF were closely correlated with full-term neonatal RDS. Hence these could provide a significant reference for the diagnosis and treatment of term neonatal RDS.

Ceruloplasmin and Alkaline Phosphatase Levels in Preterm Delivery

Introduction:Preterm birth (PTB) is a major determinant of neonatal mortality and morbidity. Preterm babies are prone to serious illness or death during the neonatal period.PTB is one of the unresolved problems in clinical obstetrics and one of the greatest threats to the developing fetus, there is need to determine predictive biomarker for preterm delivery. Therefore present study aimed to assess serum levels of ceruloplasmin and Alkaline phosphatase inpreterm and full-term delivery.Materials andMethods:The present study includes total 80 subjects that comprise forty women presenting with preterm onset of labor followed by delivery and forty women who delivered at term served as controls.Blood Samples from the subjects were obtained for ceruloplasmin and Alkaline phosphatase estimation, when patient was in labor.Serum ceruloplasmin and alkaline phosphatase measured spectrophotometrically. Serum ceruloplasmin was estimated by Herbert A Ravinand Henry et al.method. Serum alkaline phosphatase was estimated by Kinetic p-NPP method.Results:Serum ceruloplasmin levels were significantly increased (P<0.001) in preterm delivery as compared to full term delivery. Alkaline phosphatase levels are significantly increased in preterm delivery (p<0.001) as compared to full term delivery. Conclusion: Our study showed that elevated levels of ceruloplasmin and alkaline phosphatase may be associated with preterm delivery in asymptomaticpregnant women. The elevated ALP may be due to mild chronic subclinical infection which may be responsible for preterm delivery. Ceruloplasmin is acute phase reactant,increaseddue toanantioxidant defence mechanism against oxidative stress.

Prevalencia de la alimentación exclusiva con lactancia materna en recién nacidos sanos / Prevalence of exclusive breastfeeding in the healthy newborn

Resumen Introducción: El mejor alimento para los niños durante los primeros seis meses de vida es la lactancia materna exclusiva (LME); se recomienda continuar con el amamantamiento junto con otros alimentos que complementen la alimentación hasta los dos años o más, mientras madre e hijo lo deseen. Los objetivos de este estudio fueron determinar la tasa de LME en los recién nacidos a término (RNT) en el momento del alta hospitalaria y a los 15 días y analizar los factores que influyen positivamente en la LME. Métodos: Estudio prospectivo en el que se reclutó una muestra de puérperas con hijos a término durante su ingreso. Se recogieron diferentes variables y se realizaron dos entrevistas para determinar el tipo de alimentación que estaban dando a sus hijos y si se mantenía a los 15 días del parto. Resultados: La tasa de LME al recibir el alta hospitalaria es muy inferior a lo recomendado. Ésta disminuye de manera importante a los 15 días del parto, cuando aumenta la lactancia artificial (LA). Al parecer, el parto eutócico, no presentar complicaciones en el parto, realizar lactancia materna (LM) precoz y el contacto piel con piel en el paritorio son factores favorecedores para establecer una buena LM en el alta hospitalaria. Conclusiones: A pesar de los esfuerzos de los profesionales, el porcentaje de recién nacidos (RN) alimentados con LME al nacer no alcanza las recomendaciones actuales.

Abstract Background: The best nourishment for infants during the first 6 months of life is exclusive breastfeeding. It is recommended along with other food to complement the diet until the child is 2 years old, as long as the mother and the child are willing to continue with it. The objectives of this study were to determine he exclusive breastfeeding rate in full term newborns at hospital discharge and 15 days later and to analyze the factors that positively affect the exclusive breastfeeding. Methods: A prospective study was conducted in which a sample of postpartum women with full term newborns was recruited during hospital admission. Different variables were compiled and two interviews were made to determine the kind of feeding they were giving their children and if it was maintained at 15 days of birth. Results: Exclusive breastfeeding rate at hospital discharge is much lower than recommended. It significantly decreases at 15 days of birth, increasing artificial feeding. It seems that having a vaginal birth, no complications giving birth, providing early breastfeeding and skin-to-skin contact in the delivery room are predisposing factors necessary to establish a good breastfeeding at hospital discharge. Conclusions: Despite the efforts of professionals, the percentage of newborns with exclusive breastfeeding at birth is not enough for the current recommendations.

Risk factors for respiratory distress syndrome in full-term neonates / 영남의대학술지

BACKGROUND: Respiratory distress syndrome (RDS) is a one of the most common cause of respiratory morbidity and mortality in neonates. This study was conducted to investigate the risk factors for RDS in full-term neonates.METHODS: We conducted this retrospective study using medical records. The study group included 80 full-term neonates diagnosed with RDS and hospitalized in the neonatal intensive care unit between January 2012 and December 2016, at Yeungnam University Hospital. We analyzed sex, gestational age, birth weight, delivery method, maternal age, number of pregnancy, history of abortion, and complication of pregnancy. The control group included 116 full-time neonates who were hospitalized with jaundice during the same period.RESULTS: The incidence of full-term RDS was more common in males (odds ratio [OR], 3.288; 95% confidence interval [CI], 1.446–7.479), cesarean section (OR, 15.03; 95% CI, 6.381–35.423), multiparity (OR, 4.216; 95% CI, 1.568–11.335). The other factors rendered no significant results.CONCLUSION: The risk factors for RDS in full-tern neonates were identified as male sex, cesarean section, and multiparity. Further studies involving more institutions are needed to clarify the risk factors for RDS in fullterm infants.

Prognostic effect of intrauterine pregnancy induced by different methods of cervical ripening / 中国基层医药

Objective@#To investigate the effect of different cervical ripening methods on induction of labor in term pregnancy.@*Methods@#160 cases of labor induction of full-term pregnancy primipara were selected as the research subjecs.According to the different methods of cervical ripening, they were divided into two groups.The observation group (n=80) underwent dinoprostone suppositories induced labor, the control group (n=80) received intravenous infusion of small dose of oxytocin.The cervical Bishop score, cervical ripening effect, induction of labor, mode of delivery, neonatal outcome were observed in the two groups.@*Results@#Before treatment, the Bishop scores of the two groups had no statistically significant difference (t=0.436, P>0.05). After treatment for 24h, the Bishop score of the observation group was (8.3±2.6)points, which was higher than (5.9±2.0)points of the control group (t=6.544, P<0.05). In the observation group, the total effective rate of cervical ripening was 95.0%, which was higher than 66.2% of the control group (Z=-5.716, P<0.05). The duration of labor in the observation group was (12.6±4.5)h, which was significantly shorter than (21.7±7.8)h in the control group (t=9.039, P<0.05). The total labor, postpartum hemorrhage volume had no statistically significant differences between the two groups (t=2.298, 1.102, all P>0.05). In the observation group, 66cases (82.5%) were vaginal delivery, 14cases(17.5%) were cesarean section, those were 49cases(61.2%) and 31cases(38.8%) in the control group.The delivery mode of the observation group was significantly better than that of the control group(χ2=8.935, P<0.05). There were no statistically significant difference between the two groups in neonatal birth weight and postnatal 1min and 5min Apgar scores (all P>0.05).@*Conclusion@#Parturient with dinoprostone suppositories full-term pregnancy abortion can improve the cervical Bishop score and cervical ripening effect, improve the quality of delivery, it is better than oxytocin, and worthy of clinical application.

Comparison of two kinds of cervical ripening balloons in promoting full-term pregnancy cervical mature and inducing labor / 实用医学杂志

Objective To explore the clinical effects of single-cavity and COOK cervical ripening balloon in promoting full-term pregnancy cervical mature and inducing labour. Methods 126 puerpera who were expect-ant in the obstetrics department of our hospital were selected from January 2016 to June 2017,and all of the puer-pera were induced labor by cervical ripening balloon.In 61 of them,single-cavity balloon was used,and 65 cases were induced labor by COOK balloon. Determining the cervical ripening situation,the time needed for inducing efficient uterine contraction,the first stage of labor time,the total labor time,vaginal delivery rate,natural labor situation,postpartum hemorrhage,amniotic fluid turbidity,puerperal infection and newborn asphyxia of the two groups.Results the time needed for inducing efficient uterine contraction of the two groups were(16.39±2.68)h, (14.54 ± 3.30)h,and the two groups were statistically different(P<0.05).There were no statistically significant differences in other items of two groups(P>0.05).Conclusion single-cavity balloon and COOK balloon are sim-ilar in promoting full-term pregnancy cervical ripening.The difference is that the time needed for inducing efficient uterine contraction of the single-cavity balloon is longer than COOK balloon,but have no adverse effect to the puer-pera and the newborn.Both types of balloons are recommended to be used in promoting full-term pregnancy cervical ripening and inducing labor.

Durante o período de internação, o recém-nascido (RN) é submetido a uma série de procedimentos dolorosos ou não, que podem incidir sobre o seu comportamento e sobre a confiança da mãe para o cuidado e para a amamentação materna. Temos como questionamento, se sacarose 25% que é oferecida como medida de alivio da dor em RN a termo internado em alojamento conjunto interfere negativamente na amamentação materna exclusiva durante a internação. Objetivo: Verificar a associação entre uso da sacarose 25% que é oferecida como medida de alívio dor aguda em RN a termo, e a amamentação materna durante a internação em alojamento conjunto. Métodos: Trata-se de um estudo observacional, transversal, descritivo e analítico. A amostra foi constituída por 215 binômios cujo nascimento e internação ocorreram entre os meses de Junho a Setembro de 2017 em uma maternidade do interior paulista intitulada "Amiga da Criança". Os binômios foram incluídos no estudo somente após autorização da mãe, com assinatura de um termo de consentimento livre e esclarecido. Os dados foram coletados por meio do prontuário e planilhas especificas. Os RN foram divididos em dois grupos: RN expostos e não expostos ao uso da sacarose durante a internação. Como houve diferença estatística entre os grupos para o tempo de internação, para analisar a influência do uso da sacarose na amamentação durante toda internação, foi feita uma relativização das variáveis de aleitamento materno pelo total de dias de internação do RN. As associações foram verificadas pelo teste "U" de Mann-Whitney, com valor de p significativo para ? <= 0,05. Resultado: Dos 215 RN estudados durante toda internação, 111 (51,6%) RN foram expostos ao uso da sacarose. Foi utilizado sacarose para 188 (60,1%) dos procedimentos dolorosos, sendo que a mesma foi usada associada a outros métodos como o colo em 18 (5,7%) e sucção não nutritiva 64 (20,4%) dos procedimentos. Somando-se o uso isolado ou em associação a outras medidas, a sacarose foi utilizada 270 (86,2%) vezes sendo a medida mais aplicada na prática clínica da maternidade. No grupo que utilizou sacarose as médias de frequência de mamadas, uso de copo, translactação, tempo médio por mamada e amamentação assistida foram respectivamente: 7,9, 0,2, 0,5, 11,4 e 1,0 . No grupo que não utilizou a sacarose, respectivamente, as a médias das mesmas variáveis foram de 8,7, 0,03, 0,06, 18,6 e 0,8. Houve diferença estatisticamente significativa entre os grupos para as variáveis de alimentação: frequência de mamada (p=0,03), utilização de copo (p=0,01), realização de translactação (p=0,00), tempo médio por mamada (p=0,00) e amamentação assistida (p=0,02). Conclusão: As associações dos dados encontrados comprovaram a hipótese do presente estudo, ou seja o uso da sacarose a 25% para alívio da dor aguda influenciou negativamente na amamentação materna do RN durante a internação, pois, o grupo de RN que recebeu esta substância adocicada durante os procedimentos de punção arterial, venosa e capilar, apresentou menor frequência de mamada, menor tempo médio por mamada, maior uso de complemento lácteo, mais necessidade de translactação e necessitou de mais amamentação assistida por um profissional de enfermagem, quando comparado ao grupo de RN não expostos a ela. Faz-se necessária a inclusão de medidas não farmacológicas com a participação da mãe em substituição à sacarose, uma vez que tratou-se de pesquisa em uma Maternidade Amiga da Criança

Introduction: During the period of hospitalization, full-term newborns (NB) undergo a series of painful procedures, which may affect his behavior and the mother's confidence in both taking care of and breastfeeding the baby. We question whether 25% sucrose, which is offered as a measure of pain relief in hospitalized NB infants, negatively interferes with exclusive mother's breastfeeding during hospitalization in rooming-in care. Aim: Verify the association between the use of 25% sucrose offered as pain relief in full-term newborns and exclusive mother's breastfeeding during hospitalization in shared rooms. Methods: This is a study based on observation, and it is transversal, descriptive and analytical study. The sample consisted of 215 binomials whose birth and hospitalization occurred between June and September of 2017 in a maternity hospital in the countryside of São Paulo, in a Child-Friendly Maternity. The binomials were included in the study only after authorization obtained from the mother, with the signing of a free and previously informed consent form. The data were collected through medical records and specific worksheets. The NB were divided into two groups: NB exposed and not exposed to the use of sucrose during hospitalization, respectively. There was a statistical difference between the groups due to the hospitalization period; thus, to analyze the influence of sucrose use on breastfeeding during all hospitalization, a relative analysis of the variables of breastfeeding by the total number of days of hospitalization of the newborn was made. Associations were verified by the Mann-Whitney "U" test, with a significant p value for ? <= 0.05. Results: From 215 NBs studied during all hospitalization, 111 (51.6%) were exposed to the use of sucrose. Sucrose was applied for 188 (60.1%) of the painful procedures, and it was used in association with other methods such as lap in 18 (5.7%) and non-nutritive suction in 64 (20.4%) of the procedures. Added the isolate use or in association with other measures, sucrose was used 270 (86.2%) times, being the most applied measure in clinical practice of maternity. In the sucrose group, the average of frequency of feeding, cupping, translactation, average time per feeding and assisted breastfeeding were respectively: 7.9, 0.2, 0.5, 11.4 and 1.0. In the nonsucrose group, the average of the same variables were 8.7, 0.03, 0.06, 18.6 and 0.8, respectively. There was a statistically significant difference between the groups for feeding variables: feeding frequency (p = 0.03), cup use (p = 0.01), translactation (p = 0.00), average time per feed (p = 0.00) and assisted breastfeeding (p = 0.02). Conclusion: The associations of the data confirmed the hypothesis of the present study, that is, the use of sucrose at 25% for acute pain relief influenced negatively the maternal breastfeeding of newborns during hospitalization, since the group of newborns who received this sugary substance during the venous and capillary puncture procedures, presented lower breastfeeding frequency, lower average time for breastfeeding, greater use of milky complement, higher need for translactation and required more breastfeeding assisted by a nursing professional, when compared to the NB group who was not exposed to it. It is necessary to include non-pharmacological measures with the participation of the mother instead of sucrose, since it was a research in a Child-Friendly Maternity

A comparison between preterm and full-term infants' preference for faces / Uma comparação entre recém-nascidos prematuros e a termo na preferência por faces

Abstract: Objective: Visual preference for faces at birth is the product of a multimodal sensory experience experienced by the fetus even during the gestational period. The ability to recognize faces allows an ecologically advantageous interaction with the social environment. However, perinatal events such as premature birth, may adversely affect the adequate development of this capacity. In this study, we evaluated the preference for facial stimuli in preterm infants within the first few hours after birth. Methods: This is a cross-sectional observational study of 59 newborns, 28 preterm and 31 full-term infants. The babies were assessed in the first hours of life, with two white boards in the shape of a head and neck: one with the drawing of a face similar to the human face (natural face), and one with the drawing of misaligned eyes, mouth and nose (distorted face). After the newborn fixated the eyes on the presented stimulus, it was slowly moved along the visual field. The recognition of the stimulus was considered present when the baby had eye or head movements toward the stimulus. Results: The preterm infants, in addition to showing a lower occurrence of orientation movements for both stimuli, on average (1.8 ± 1.1 to natural faces and 2.0 ± 1.2 for distorted ones) also showed no preference for any of them (p = 0.35). Full-term newborns showed a different behavior, in which they showed a preference for natural faces (p = 0.002) and a higher number of orientations for the stimulus, for both natural (3.2 ± 0.8) and distorted faces (2.5 ± 0.9). Conclusion: Preterm newborns recognize facial stimuli and disclose no preference for natural faces, different from full-term newborns.

Resumo: Objetivo: A preferência visual por faces ao nascimento é produto de uma experiência sensorial multimodal vivenciada pelo feto ainda no período gestacional. A habilidade de reconhecer faces possibilita uma interação ecologicamente vantajosa com o ambiente social. Entretanto, eventos perinatais, como o nascimento prematuro, podem prejudicar o desenvolvimento adequado dessa habilidade. Neste trabalho, avaliamos a preferência por estímulos faciais de recém-nascidos prematuros nas primeiras horas após o nascimento. Métodos: Trata-se de um estudo observacional transversal feito com 59 recém-nascidos, 28 prematuros e 31 nascidos termos. Os bebês foram avaliados, nas primeiras horas de vida, com duas pranchas brancas em formato de cabeça e pescoço: uma com o desenho de uma face similar ao rosto humano (face natural) e outra com o desenho de olhos, boca e nariz desalinhados (face distorcida). Após o recém-nascido fixar o olhar no estímulo apresentado, era lentamente movimentado ao longo do campo visual. O reconhecimento do estímulo foi considerado presente quando o bebê apresentou movimentos dos olhos ou cabeça em direção ao estímulo. Resultados: Os recém-nascidos prematuros, além de apresentar menor ocorrência de movimentos de orientação para ambos os estímulos, em média (1,8 ± 1,1 para faces naturais e 2 ± 1,2 para faces distorcidas), também não apresentaram preferência por qualquer um deles (p = 0,35). Diferente foi o comportamento dos recém-nascidos a termo, que apresentaram preferência por faces naturais (p = 0,002) e um número maior de orientações para o estímulo, tanto para faces naturais (3,2 ± 0,8) quanto para faces distorcidas (2,5 ± 0,9). Conclusão: Recém-nascidos prematuros reconhecem os estímulos faciais e não apresentam preferência por faces naturais, diferentemente de recém-nascidos a termos.

Objetivo: Determinar la frecuencia, tasa de cesárea y riesgos de morbimortalidad del recién nacido a término precoz (RNTP). Material y métodos: Estudio observacional, retrospectivo, analítico. Se incluyó a neonatos únicos vivos a término, nacidos en el hospital Hipólito Unanue de Tacna durante los años 2000 a 2014 (n=45332). Se comparó a los nacidos a termino precoz de 37 a 38 6/7 semanas (n=11276), y los nacidos a termino completo de 39 a 41 6/7 semanas (n=34056). Se utilizó frecuencia y tasa por 100 nacidos vivos, odds ratio (OR) con intervalos de confianza al 95% (IC 95%), regresión logarítmica y prueba "t" para muestras independientes. Se utilizó la base de datos del Sistema Informático Perinatal. Resultados: La frecuencia de nacidos a término precoz fue 22,5 por 100 nacidos vivos, con un crecimiento logarítmico significativo (p=0,03). Representó 24,9% de todos los recién nacidos a término. La tasa de cesárea se incrementó de 31,2% a 51,1% y su crecimiento fue similar al de los término completo. Se asoció al RNTP con mayor probabilidad de tener bajo peso al nacer (OR:5,33; IC 95%: 4,50-6,30), ser pequeño para la edad gestacional (OR:3,14; IC 95%: 2,69- 3,66), nacer por cesárea (OR: 3,15; IC 95%: 3,01-3,29), tener estancia hospitalaria de 3 días a más (OR: 1,46; IC 95%: 1,39-1,54), morbilidad respiratoria (OR: 1,81; IC 95%: 1,38-2,37) como neumonía (OR:3,02; IC 95%: 1,70-5,38), membrana hialina (OR: 4,17; IC 95%: 1,56-11,33) y taquipnea transitoria (OR: 2,95; IC 95%: 1,79-4,85); y malformaciones congénitas (OR: 1,46; IC 95%: 1,17-1,82), hiperbilirrubinemia (OR: 1,23; IC 95%: 1,02-1,49) y mortalidad neonatal (OR: 2,17; IC 95%: 1,45-3,23). Conclusión: La frecuencia de recién nacidos a término precoz en el hospital Hipólito Unanue de Tacna se incrementó en los últimos 15 años y se asoció a mayor riesgo de problemas respiratorios y mortalidad neonatal

Objective: To determine the frequency, cesarean section rate and morbidity and mortality risks for early term newborns. Material and methods: Non-experimental, cross-sectional study. We included single term live neonates born in Hipolito Unanue Hospital in Tacna from 2000 to 2014 (n= 45332). Early term newborns from 37 to 38 6/7 weeks (n= 11276), were compared with full term newborns from 39 to 41 6/7 weeks (n= 34056). We used frequencies and rates per 100 live births, odds ratios (OR) with 95% confidence intervals (95% CI), logarithmic regression and "t" test for independent samples. The Perinatal Computer System database was used. Results: The frequency of preterm infants was 22.5 per 100 live newborns, with a significant logarithmic growth (p= 0.03). This accounted for 24.9% of all full term newborns. The cesarean section rate increased from 31.2% to 51.1% and its growth was similar to that of full term newborns. It was associated with a higher risk of low birth weight (OR: 5.3; 95% CI:4.5-6.3), small for gestational age babies (OR: 3.14; 95% CI: 2.69-3.66), being born by cesarean section (OR: 3.15; 95% CI: 3.01-3.29), hospital stay of 3 days or more (OR: 1.46; 95% CI: 1.39-1,54), respiratory morbidities (OR: 1.81; 95% CI: 1.38-2.37), such as pneumonia (OR: 3.02; 95% CI: 1.70-5.38), hyaline membrane (OR: 4.17; IC 95% CI: 1.56-11.33), and transient tachypnea (OR: 2.95; 95% CI: 1.79-4.85); and congenital malformations (OR: 1.46; IC 95% CI: 1.17-1.82), hyperbilirubinemia (OR: 1.23; 95% CI: 1.02-1.49), and neonatal mortality (OR: 2.17; 95% CI: 1.45-3.23). Conclusion: The frequency of early term newborns in Hipolito Unanue Hospital in Tacna increased in the last 15 years, and it was associated with an increased risk of respiratory problems and neonatal mortality

Measurement of tidal respiration in ＜ 34 weeks premature infants with respiratory clistress syndrome at 40 weeks corrected gestational age / 中华急诊医学杂志

Objective To investigate pulmonary function in terms of tidal respiration and the influencing factors on it in ＜ 34 weeks premature infants with RDS at corrected gestational age of 40 weeks.Methods A total of 49 of ＜ 34 weeks premature infants with RDS (RDS group) and 36 of ＜ 34 weeks premature infants without RDS (non-RDS group) followed throughout entire twelve months were collected fromn December 2013 to October 2015.Of them,35 RDS patients and 20 non-RDS patients had the pulmonary function examination.A total of 26 full term infants with hyperbilirubinemia (full term group) were recruited for comparison study.The differences in parameters of tidal respiration were compared among the three groups.The RDS patients were further divided into the mild RDS subgroup and severe RDS subgroup according to the severity of illness.Result ①The TPEF [(0.17 ± 0.04) s vs.(0.23 ± O.09) s],VPEF [(6.74±2.70) mLvs.(9.33±2.92) mL],TPEF/TE [(29.06±4.21)％ vs.(38.27± 7.16) ％],VPEF/VE [(32.54 ± 4.43) ％ vs.(39.64 ± 5.88) ％] in RDS group were significantly lower than those in full term group (P ＜0.05).The TPEF [(0.19 ±0.06) s vs.(0.23 ±0.09) s],TPEF/TE [(30.31 ±11.53)％ vs.(38.27±7.16)％],VPEF/VE [(34.39±8.44)％ vs.(39.64±5.88)％] in non-RDS group were significantly lower than those in full termn group (P ＜ 0.05).The TPEF,TPEF/TE,VPEF/VE in RDS group were lower than those in non-RDS group,but the differences were not significant (P ＞ 0.05).②The TPEF,VPEF,TPEF/TE,VPEF/VE in mild RDS group were higher than those in severe RDS group,but the differences were.not significant (P ＞ 0.05).③ Logistic regression analysis indicated that the gestational age was the protective factor of pulmonary function in premature infants with RDS.Conclusions Small airway resistance in ＜ 34 weeks premature infants with RDS is higher than that in full term infants.There was no significant difference in pulmonary function between RDS premature infants and non-RDS premature infants.The gestational age was the influencing factor of pulmonary function in premature infants with RDS.
