RESUMO

Objective:To study the effects of breastfeeding within 2 weeks after birth on late-onset sepsis in very low birth weight infants (VLBWI).Methods:From July 2018 to June 2019, clinical data of VLBWI (birth weight <1 500 g) born in our hospital were retrospectively reviewed. According to the proportion of breastfeeding volume in total feeding volume within 2 weeks after birth, the infants were assigned into high-proportion breastfeeding group (breastfeeding >50%), low-proportion breastfeeding group (breastfeeding ≤50%) and formula group. The incidences of late-onset sepsis among the three groups were compared using the chi-square test or Fisher's exact probability method. Logistic regression was used to analyze the effects of breastfeeding within 2 weeks after birth on late-onset sepsis.Results:The incidences of late sepsis in high-proportion breastfeeding group, low-proportion breastfeeding group and formula group were 0.4% (1/216), 8.1% (5/62) and 8.0% (2/25), respectively ( P<0.001). Logistic regression analysis showed that compared with the high-proportion breastfeeding group, the low-proportion breastfeeding group ( OR=17.844, 95% CI 2.005~158.775) and the formula group ( OR=23.261, 95% CI 1.916~282.350) had increased risks of late-onset sepsis. Conclusions:For VLBWI, high proportion breastfeeding (breastfeeding >50%) within 2 weeks after birth may reduce the risk of late-onset sepsis.

RESUMO

Objective:To study the incidence and risk factors of periventricular- intraventricular hemorrhage (PIVH) in extremely preterm infants (EPI) with gestational age (GA)<28 weeks.Methods:A retrospective study was performed in 304 cases of EPI hospitalized between January 2016 and December 2018. The infants were assigned into two groups according to whether PIVH occurred. Univariate analysis and Logistic regression analysis were used to determine the risk factors of PIVH.Results:Among the 304 cases,101 (33.2%) developed PIVH and 44 (14.5%) developed severe PIVH.The incidences of PIVH and severe PIVH in EPI with birth weight (BW) <750 g were 50.6% and 31.0%. The incidences of PIVH and severe PIVH in EPI with GA<26 weeks were 51.4% and 27.5%. Logistic regression analysis revealed that advanced GA ( OR=0.697, 95% CI 0.543~0.895, P=0.005) decreased the risk of PIVH. Prolonged invasive mechanical ventilation ( OR=1.121, 95% CI 1.007~1.249, P=0.037) and use of vasoactive drugs ( OR=1.373, 95% CI 1.040~1.812, P=0.025) within the first week of life increased the risk of PIVH. Conclusions:The incidences of PIVH and severe PIVH in EPI are quite high. Smaller GA, longer use of invasive mechanical ventilation and vasoactive drugs within the first week will increase the risk of PIVH in EPI.

RESUMO

Objective:To analyze the cases referred to a higher-level hospital from the Department of Neonatology in a primary hospital, and evaluate the efficiency of clinical works related to the referrals.Methods:Data of neonates admitted to the Department of Neonatology at Maternal and Child Health Hospital of Dabu County from January 2018 to December 2020 and referred to the superior hospital were retrospectively analyzed.Results:A total of 1 670 neonates were included and 128 neonates were referred.The median age of the neonates referred was 0.5 hours(0 hours, 25 days), the median gestational age was 38 + 3(29 + 1, 42 + 4) weeks, the median weight was 3 000(1 250, 4 800) g, and the transport distance was 78 km.Twenty-four cases were assessed as critical cases before the referral, 125 cases were improved and discharged after treatment in the superior hospital, and three cases died.The referral rate in 2018, 2019 and 2020 showed a downward trend year by year (10.3%, 7.6% and 4.0%, respectively), and the difference was statistically significant( χ2=14.362, P=0.001). The proportion of critical cases in referral cases increased year by year (9.4%, 23.9% and 38.9%, respectively), and the difference was statistically significant( χ2=9.289, P=0.010). The incidence of critical case was higher in those whose mothers didn′t have regular prenatal examination during pregnancy( χ2=5.129, P=0.032). Conclusion:The ability of neonatal treatment in primary hospitals has been improved.The neonates need to be referred and critical cases are not rare in primary hospitals.More attention should be paid to the safety and effectiveness of the regional transport network.Also, enhancing the health awareness of residents and improving the primary medical technics are important to maximize the life safety and optimal transition of newborns.

RESUMO

Objective:To study the risk factors of hypotension after ligation of patent ductus arteriosus (PDA) in very/extremely low birth weight infants (VLBWI/ELBWI).Method:From March 2016 to January 2021, preterm infants with birth weight <1 500 g receiving bedside PDA ligation in the neonatal intensive care unit (NICU) of our hospital were enrolled in the study. According to the occurrence of hypotension within 72 hours after ligation, the infants were assigned into non-hypotension group and hypotension group. The general status and perioperative conditions of the two groups were analyzed. Multivariate Logistic regression was used to analyze the risk factors of hypotension.Result:A total of 44 cases were enrolled, including 33 in non-hypotension group and 11 in hypotension group. Univariate analysis showed that hypotension group had significantly more cases with body weight <1 100 g during surgery and receiving preoperative high frequency oscillatory ventilation (HFOV) than non-hypotension group ( P<0.05). Multivariate Logistic regression analysis showed that weight <1 100 g during surgery ( OR=12.045, 95% CI 1.351~107.394, P=0.026) and receiving preoperative HFOV ( OR=27.832, 95% CI 1.363~568.292, P=0.031)were independent risk factors of hypotension. Conclusion:Hypotension is one of the common complications of PDA ligation in VLBWI/ELBWI. The infant's body weight during ligation and receiving preoperative HFOV are independent risk factors of hypotension.

RESUMO

Objective:To study the effects of early breastfeeding volume on neonatal necrotizing enterocolitis (NEC) and feeding intolerance in very low birth weight infants.Methods:This study retrospectively analyzed the clinical data of 275 cases of very low birth weight infants (birth weight<1 500 g) born in Shenzhen Maternity & Child Healthcare Hospital from June 2017 to May 2018. Based on whether breastfeeding or not and the ratio of breast milk intake over the total volume of intake within two weeks after birth, they were divided into three groups: breast milk intake>50% group (>50% group, n=199), breast milk intake≤50% group (≤50% group, n=55) and formula group ( n=21). Differences in the incidence of NEC and feeding intolerance among the three groups were analyzed using Chi-square test (or Fisher's exact test). Effects of breast milk intake on the incidence of NEC and feeding intolerance were evaluated using univariate and multivariate logistic regression analysis. Results:The incidence of NEC in the >50% group, ≤50% group and formula group was 1.5% (3/199), 27.3% (15/55) and 9.5% (2/21), respectively ( P<0.01), and the incidence of feeding intolerance was 17.6% (35/199), 56.4% (31/55) and 28.6% (6/21), respectively ( χ2=34.826, P<0.01). Univariate logistic regression analysis showed that compared with the >50% group, the risk of NEC in the≤50% and formula group increased ( OR=24.500, 95% CI: 6.755-85.594; OR=6.877, 95% CI: 1.081-43.744); that of feeding intolerance increased in the≤50% group ( OR=6.316, 95% CI: 3.293-12.113). Multivariate logistic regression analysis showed that compared with the >50% group, the risk of NEC in the≤50% and formula groups increased ( OR=28.452, 95% CI: 7.280-111.195; OR=8.610, 95% CI: 1.262-58.766); that of feeding intolerance increased in the≤50% group ( OR=7.207, 95% CI: 3.601-14.425). Conclusions:Breastfeeding accounting for more than half of the total volume of intake within two weeks after birth may reduce the incidence of feeding intolerance and NEC in very low birth weight infants.

RESUMO

Objective To analyse the risk factors associated with spontaneous intestinal perforation (SIP) in extremely premature infants/extremely low birth weight infants. Method From January 2015 to December 2018, infants with gestational age (GA)<28 weeks or birth weight (BW)<1000 g admitted to our neonatal intensive care unit were enrolled to the retrospective nested case-control study.The clinical data of SIP infants (SIP group) and infants with the same GA but without SIP (control group) were randomly selected and compared. Multivariable Logistic regression was used to analyse the risk factors of SIP. Result A total of 409 extremely premature infants/extremely low birth weight infants were born during the study period. Among them, 25 SIP infants and 55 controls were enrolled. The incidence of SIP in infants with GA 22~25 weeks was 11.8%(16/136), which is higher than infants with GA 26~27 weeks (2.0%, 5/247) (χ2=16.057, P<0.001). The incidence of SIP in infants with BW 400~749 g was 13.0%(14/108), which is higher than infants with BW 750~999 g (3.4%, 8/236) (χ2=11.343, P=0.001). Multivariate Logistic regression analysis showed that twins (OR=4.153, 95%CI 1.392~12.384, P=0.011), umbilical veins catheterization (OR=15.942, 95%CI 1.026~247.789, P=0.048) and ibuprofen use within 3 days after birth (OR=15.387, 95%CI 1.519~155.883, P=0.021) were independent risk factors of SIP. Conclusion The smaller the GA and BW, the higher the incidence of SIP. Twins,umbilical veins catheterization and ibuprofen use early after birth may be independent risk factors of SIP.

RESUMO

Objective To evaluate the value of monitoring non-invasive cardiac output parameters in medical treatment of patent ductus arteriosus (PDA) in premature infants.Method Premature infants with PDA diagnosed three days after birth (gestational age:28 ~ 31 weeks or birth weight of 1 000 ~ 1 799 g) admitted to the neonatal intensive care unit (NICU) of our Hospital from February 2016 to August 2016 were enrolled in the study.These premature infants were assigned into treated PDA group (the treatment group) and untreated PDA group (the observation group) based on results of non-invasive cardiac output parameters CI and MD,with aorta CI ≥2.95 L/(min · m2),MD ≥21.50 m/min and pulmonary artery CI ≥4.55 L/(min · m2),MD ≥26.50 m/min as cut-off values.Statistical analysis was carried out using t test,x2 test.The closure rate of arterial duct of two groups and changes in non-invasive cardiac output parameters before and after the closure of arterial duct in the treatment group were compared.Result The overall closure rate of arterial duct was 85.1% (57/67).The closure rate of arterial duct of the treatment group was 70.8% (17/24),that of the observation group was 93.0% (40/43),and the difference had statistical significance (P < 0.05);Comparing the following parameters before and after ductal closure in the treatment group,the difference of pulmonary artery flow time (FT),aorta stroke volume index (SVI) and the integral of the flow profile (Vti) had statistical significance (P < 0.05) [(217.6±19.3) ms vs.(235.8 ±21.4) ms,(22.4±6.0)ml/m2 vs.(25.2 ±7.7)ml/m2,(15.1 ± 4.1) cm vs.(17.2 ±5.3) cm].In the treatment group,after arterial duct was closed,aorta and pulmonary artery CI,MD decreased to some degree,but the difference had no statistical significance (P > 0.05).Conclusion Non-invasive cardiac output parameters including aorta and pulmonary artery CI,MD have certain guiding significance for PDA drug treatment among premature infants;after PDA drug treatment,arterial duct closure condition cannot be judged simply by the changes of aorta and pulmonary artery CI,MD,ultrasonic cardiogram examination results should also be considered.

RESUMO

Objective To analyze the incidence of retinopathy of prematurity(ROP)among extreme-ly preterm infants,and to evaluate the treatment methods and effects among those with severe ROP.Methods A retrospective analysis was performed to analyze incidence of ROP in 96 cases of extremely preterm infants who were born at a gestational age of 〈28 weeks and survived beyond a postmenstrual age of at least 1 year from Apr 2006 to Oct 2013,and to analyze the treatment outcomes of photocoagulation and ranibizum-ab intravitreal injection among the infants with severe ROP.Results Fifty-six of 96 cases(58.33%)grew into ROP finally and 21 cases(21.88%)grew into severe ROP,2 cases(2.08%)grew into aggressive poste-rior ROP.Fifteen cases with severe ROP were treated with laser photocoagulation.Four cases with severe ROP were received ranibizumab intravitreal injection prior to photocoagulation.Two cases with severe ROP were only treated with ranibizumab intravitreal injection.The eyesight of 96 patients (100%)in this study were all preserved.Conclusion ROP screening should focus on extremely preterm infants because of higher incidence of ROP and severe ROP among them.The infants with severe ROP should be treated with laser photocoagulation in time.The infants in critical condition or with aggressive posterior ROP can be treated with ranibizumab injection.

RESUMO

Objective To investigate the cause and clinical characteristics of neonatal thrombocytopenia (NT).Methods A retrospective analysis was performed.71 cases with NT were selected as our subjects.The morbidity of NT was calculated.Results Among the 71 cases with NT,34 were term infants and 37 were preterm infants.The morbidity of NT in preterm infants was significantly higher than that in term infants (x2 =24.56,P <0.01).Common causes for NT included intrauterine growth restriction(IUGR),severe asphyxia,severe sepsis or necrotizing enterocolitis (NEC).IUGR was the more frequent cause for early-onset thrombocytopenia than for late-onset thrombocytopenia (x2 =9.20,P =0.002).Severe sepsis or NEC was the more frequent cause for late-onset thrombocytopenia than for early-onset thrombocytopenia (x2 =13.58,P < 0.01).The cases of bleeding in mild thrombocytopenia group was less than that in severe thrombocytopenia group(x2 =5.85,P =0.016).Conclusion IUGR which is the common cause for NT frequently induces earlyonset thrombocytopenia.Severe sepsis or NEC frequently induces late-onset thrombocytopenia accompanied with high bleeding risk.Earlier diagnosis of the cause for NT and tailed treatments can achieve better efficacy.

RESUMO

ObjectiveTo study the feasibility,efficacy and safety of u tilizing the laryngeal mask airway (LMA) ventilation compared with the endotracheal intubation ( ET ) in neonatal resuscitation for moderate and severe asphyxiated neonates.MethodsNeonates requiring positive pressure ventilation with heartrate <60 beats/min were collected and grouped quasi-randomizedly into LMA(36 cases) or ET(32 cases)ventilation.Differences of resuscitation effect,inserting time,successful once insertion rate and adverse reactions between the two groups were observed and compared.Results( 1 ) No significant difference was observed in Apgar scores at 1 min and 5 min between the two groups ( P>0.05 ).(2) Success rate of once insertion was 94.4% with average inserting time ( 7.58±1.16 ) s for LMP group,while it was 90.6% and ( 7.89 ± 1.52) s for ET group.( 3 ) Successful resuscitation rate of LMA group ( 86.11% ) was slightly lower than ET group (96.88% ),but there was no statistical difference (P>0.05).(4) Mean response time of LMA group [ (34.06 ± 10.56) s] was slightly lower than that of ET group [ (41.38 ±27.19) s],also ventilation time of LMA group [( 137.19 ±80.14) s] was slightly lower than that of ET group [ ( 171.09±84.28 ) s ],but neither showed statistical difference ( P>0.05 ).(5) Adverse reactions were found in LMA group including nausea( 2 cases )and abdominal distention (1 cases),while there were laryngeal edema( 1 cases),pneumothorax(2 cases),respiratory tract bleeding( 1 cases) in ET group.ConclusionThe LMA ventilation is much easier to operate,with its effect no less than that of ET ventilation on resuscitation for moderate and severe asphyxiated cases,even it seems more safe.LMA ventilation can be a good substitute for ET ventilation,especially for those medical staffs who are unfamiliar with ET operation and primary hospital doctors in case of emergency.

RESUMO

Objective To study the feasibility, efficacy and safety of laryngeal mask airway (LMA) in neonatal resuscitation. Methods Totally, 369 neonates requiring positive pressure ventilation at birth were randomized into two groups by offering either LMA resuscitation (205 cases) or bag-mask ventilation (BMV) resuscitation (164 cases). The effect in the two groups were observed. Results (1) No significant difference was observed in Apgar scores at 1 min between LMA group and BMV group, but the neonates having higher Apgar scores at 5 min in LMA group were more than in BMV group (x2 =-3. 39,P=0. 001). The successful resuscitation rate of LMA group was higher than that of BMV group (99.02%vs 84. 15% ,x2 =28. 76, P<0. 01), the total ventilation time of LMA group was shorter than that of BMV group [(36.4±23.7) s vs (66.2±35.4) s] (t=-8.66, P<0. 01). Among severe asphyxia neonates,seven of nine were successfully resuscitated by LMA, while in BMV group six neonates with severe asphyxia were all switched to endotracheal intubation ventilation. In neonates with Apgar score of 4 to 5 at 1 min after birth, the successful resuscitation rate of LMA group was higher than that of BMV group (100% vs 42. 86%, x2 =23.04, P<0.01), the ventilation time of LMA group was shorter than that of BMV group [(54.6±33.6) s vs (136.4±42.0) s] (t= -4. 45, P<0.01). In neonates with Apgar score of 6 to 7 at 1 min after birth, there was no significant difference in the successful resuscitation rate between LMA and BMV group. (2) The successful rate of LMA insertion at first attempt was 98.54% (202/205) and the average insertion time was (7.8 ± 2. 2) s. The adverse effects included vomiting(4 cases)and regurgitation (3 cases). Conclusions In neonatal resuscitation, LMA can be easily inserted. Compared to BMV, LMA is a better choice in resuscitation for neonates with moderate or severe asphyxia and preferable for those medical staffs who are unfamiliar with endotracheal intubation, or even as a substitute of endotracheal intubation ventilation.
