Anaesthetic management of a parturient with hypokalaemic periodic paralysis for caesarean section: A case report and review of the literature.

A 32-year-old multigravida woman, with known familial hypokalaemic periodic paralysis, underwent spinal anaesthesia for an elective lower segment caesarean section. There are several case reports in the literature discussing the optimal anaesthetic technique. In the past there has not been an emphasis on aggressive and early potassium replacement. A target level to commence replacement of potassium at 4.0 mmol/L or less is proposed. Careful preoperative preparation, frequent perioperative monitoring and early potassium replacement resulted in no perioperative episodes of weakness in this case, in contrast with other case reports where potassium was either not monitored or not replaced early enough, resulting in postoperative attacks. Another factor to consider in hypokalaemic periodic paralysis is the avoidance of triggers, including certain medications. Misoprostol was used in this instance to avoid potential electrolyte derangements from other uterotonics.

[Epidemiological analysis of the current prevalence of hepatitis B virus infection among pregnant and postpartum women in China from 2021 to 2023].

Objective: To analyze hepatitis B serologic tests and the current prevalence of hepatitis B virus (HBV) infection among pregnant and postpartum women in China from 2021 to 2023. Methods: Data on managing the prevention of mother-to-child transmission of HIV, syphilis, and hepatitis were retrieved from the National Information System. A positive serum HBsAg test was used to define HBV infection. The χ(2) test was used to compare the coverage rate of the hepatitis B serologic test across different years, in early-stage pregnancy, and the current HBV infection in pregnant and postpartum women. A two-sided P value of <0.05 was considered a statistically significant difference. Results: The coverage rate for hepatitis B serological detection in pregnant (including intrapartum) and postpartum women and early-stage pregnancy rose from 99.68% (10 463 059/10 496 883) and 82.96% (8 707 765/10 496 883) to 99.94% (8 678 777/8 684 387, P < 0.001) and 88.87% (7 717 857/8 684 387, P < 0.001) in China between 2021 and 2023. The current prevalence rate of HBV infection decreased from 4.98% (521 479/10 463 059) in 2021 to 4.56% (396 148/8 678 777) in 2023 among pregnant and postpartum women (P < 0.001). The current prevalence rate of HBV infection ranged from 1.53% to 10.39% among pregnant and postpartum women in various provinces of China in 2023. Conclusion: The coverage rate for hepatitis B serologic tests in China increased significantly between 2021 and 2023 in pregnant and postpartum women. Therefore, the current prevalence rate of HBV infection has decreased significantly in pregnant and postpartum women, but a regional difference still exists.

Association between labor epidural analgesia and gut microbiota: A prospective cohort study.

Background: Labor epidural analgesia (LEA) may influence gut microbiota. We explored the association between LEA and gut microbiota for both mothers and their newborns. Methods: In this prospective cohort study, parturients aged 25-35 years with a gestational age of 37-42 weeks and planned vaginal delivery were recruited. Twenty-one parturients received LEA (the LEA group), and 24 did not (the control group). Maternal and neonatal fecal samples were collected, and the gut microbiota profiles were analyzed using the 16S rRNA gene sequencing. The impact of LEA on gut microbiota was assessed using the general liner models. Results: We showcased the gut microbiota profile from the phyla to species levels based on data on 45 mother-newborn dyads. The results of α- and ß-diversity suggested significant changes in gut microbiota between the LEA and control groups. After adjusting for baseline confounders, the administration of LEA had positive correlations with R. ilealis (ß = 91.87, adjusted P = 0.007) in mothers; LEA also had negative correlations with A. pittii (ß = -449.36, adjusted P = 0.015), P. aeruginosa (ß = -192.55, adjusted P = 0.008), or S. maltophilia (ß = -142.62, adjusted P = 0.001) in mothers, and with Muribaculaceae (ß = -2702.77, adjusted P = 0.003) in neonates. Conclusion: LEA was associated with changes in maternal and neonatal gut microbiota, and future studies are still required to assess their impact on clinical outcomes and explore the mechanisms.

Influence of prenatal corticosteroid therapy on neonatal vitality and utility as a labor-inducing agent in Santa Inês ewes.

Since the 1970s, maternal corticosteroid therapy has been used successfully to induce labor. This allows for better monitoring of parturients and provision of first aid to neonates, improving neonatal viability, as this treatment induces maturation in a variety of fetal tissues, thereby reducing morbidity and mortality. Although the effects of corticosteroids are well known, few studies have investigated the influence of this therapy in Santa Inês sheep. This study aimed to evaluate the efficacy of dexamethasone at two doses (8 and 16 mg) to induce lambing in Santa Inês ewes at 145 days of gestation and assess its effects on neonatal vitality. For this study, 58 ewes raised in an extensive system were investigated. Pregnancy was confirmed after artificial insemination at a set time or after controlled mounting. Ewes were separated into three groups: an untreated control group (G1: 0 mg) and groups treated with two doses of dexamethasone (G2: 8 mg and G3: 16 mg). In total, 79 lambs were born. Their vitality was assessed based on their Apgar score, weight, temperature, and postnatal behavior. SAS v9.1.3 (SAS Institute, Cary, NC) was used to analyze data, considering a 5% significance level for all analyses. The births in the induced groups occurred 48.4 ± 22.1 h after induction, while the ewes that underwent non-induced labor gave birth 131.96 ± 41.9 h after placebo application (p < 0.05), confirming the efficacy of dexamethasone to induce and synchronize labor. The induced and non-induced neonates had similar Apgar scores, temperatures, weights, and postnatal behavioral parameters (p > 0.05). This study showed that inducing labor in Santa Inês ewes at 145 days of gestation with a full (16 mg) or half dose (8 mg) of dexamethasone is an effective technique and does not compromise neonate vitality.

The Concentration of Lactoferrin in Breast Milk Correlates with Maternal Body Mass Index and Parity.

Background: Lactoferrin (LF) is a multifunctional glycoprotein found in human milk and body fluids, which has been shown to play a vital role in regulating the immunity and supporting the intestinal health of infants. Aim: This study evaluated the association between maternal/parturient factors and LF concentration in the breast milk of Chinese mothers. Methods: 207 breast milk samples were collected from healthy mothers with in the first year of lactation. Maternal and parturient information was collected for these participants through questionnaires. The content of lactoferrin in breast milk was detected by liquid chromatography, and macronutrient concentration in breast milk was measured by human milk analyzer in only 109 samples. Results: Our findings demonstrated that the LF content was much higher within the first month of lactation than it was after that period (p < 0.05). When compared with normal and lean mothers, the LF content of obese mothers was considerably higher (p < 0.05). The parity and LF content showed a favorable correlation. The proportion of LF to total protein tended to decrease as lactation progressed. Protein, fat, dry matter, and energy content were significantly positively correlated with LF content (p < 0.001). Conclusion: Early breast milk tends to have a higher level of LF, and the change of LF concentration in breast milk is associated with the parity and body mass index of the mother.

Clinical significance of the combined test of seven blood coagulation indexes, lipids and platelet agglutination on hypercoagulable state of blood in parturient women.

Objective: To investigate the value of the combined test of seven blood coagulation indexes, lipids and platelet agglutination on the evaluation of the hypercoagulable state of blood in parturient women. Methods: This is a retrospective study. Total 50 high risk parturient women who underwent an antenatal examination in Baoding Maternal and Child Health Hospital from June 2021 to January 2023 were selected as the observation group, while 50 normal parturient women who underwent antenatal examination without comorbidities and complications were randomly collected in a ratio of 1:1 as the control group. All subjects had venous blood drawn for testing of seven blood coagulation indexes, lipids and platelet agglutination before delivery, and their general data were recorded. Results: The activated partial thromboplastin time(APTT) in the observation group was lower than that in the control group, while thrombin time(TT) and D-dimer(DD) were both higher than those in the control group, with statistically significant differences(p<0.05); total cholesterol (TC) and triglyceride (TG) in the observation group were both higher than those in the control group, with statistically significant differences (p<0.05); adenosine diphosphate (ADP) and arachidonic acid (AA) in the observation group were both higher than those in the control group, with statistically significant differences (p<0.05). Moreover, the overall incidence of adverse pregnancy was higher in the observation group than in the control group, with a statistically significant difference (p<0.05). Conclusions: The combined test of seven blood coagulation indexes, lipids and platelet agglutination results in excellent performance in predicting and judging the presence or absence of the hypercoagulable state of blood in parturient women, with the combination of APTT+TT+DD+TG+ADP+AA being the preferred test.

The diagnostic accuracy of preoperative perfusion index as a predictor of postspinal anesthesia hypotension in parturients undergoing cesarean delivery: A prospective non-blinded observational study.

Background and Objectives: Spinal anesthesia is the technique of choice for elective cesarean section with a prominent side effect of postspinal anesthesia hypotension (PSH). This needs an early prediction to avoid feto-maternal complication. This study aimed to assess the diagnostic accuracy of perfusion index (PI) and inferior vena cava collapsibility index (IVCCI) in the prediction of PSH. Material and Methods: Thirty parturients of American Society of Anesthesiologists Physical Status (ASA-PS) 1 and two undergoing cesarean delivery participated in the study. IVCCI, PI, baseline systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), and heart rate (HR) were noted in the preoperative period. The fall of MBP by 20% from baseline or below 65 mm Hg was considered PSH. After spinal anesthesia, SBP, DBP, MBP, and HR were noted again for diagnosing PSH. Results: It did not show any statistical difference when comparing the PI between the PSH and non-PSH groups in both the PSH definition groups. IVCCI was significantly higher when PSH was considered MBP <65 mm Hg (P = 0.01). However, IVCCI was found to be statistically insignificant if PSH was considered a 20% reduction in baseline MBP. The correlation matrix between IVCCI and PI showed Pearson's r-value of 0.525, indicating a substantial relationship between the two (P = 0.003). Multivariate logistic regression analysis had shown that neither IVCCI nor PI was a good predictor of PSH in parturients for both definition groups for PSH. Conclusion: Although there is a modest correlation between PI and IVCCI, both cannot be used to predict postspinal hypotension in parturients undergoing elective lower-segment cesarean section (LSCS).

Diagnostic accuracy of a simple qualitative ultrasound assessment for the diagnosis of high-risk gastric contents in the parturient. A prospective observational cohort study.

STUDY OBJECTIVE: Interpretation of gastric ultrasound relies on the use of a clinical algorithm that combines qualitative analysis of the gastric antrum contents with the calculation of the volume of fluid contents. This reference method may be difficult to apply in the parturient. We therefore aimed to assess the diagnostic accuracy of a simple qualitative assessment in the supine position for the diagnosis of high-risk gastric contents in the parturient. We also assessed the diagnostic accuracy of a composite scale and another clinical algorithm based on a mathematical model different to that used in the reference method. DESIGN: Prospective observational cohort study. SETTING: University hospital, Lyon, France. PATIENTS: Adult women admitted to the delivery room. INTERVENTIONS: Qualitative and quantitative gastric ultrasound examination within the first hour following admission. MEASUREMENTS: With respect to the reference method, the diagnostic accuracy of a simple qualitative assessment for the diagnosis of high-risk gastric contents was assessed. The diagnostic accuracy of a composite scale and another clinical algorithm, and the agreement between each approach were also assessed. MAIN RESULTS: A total of 235 parturients were included and analyzed. The simple qualitative assessment led to conclusive ultrasound assessment in 233 (99%) women, while the reference method led to conclusive assessment in 213 (91%) women (P < 0.05). The sensitivity and the specificity of the simple qualitative assessment were 97% (95%CI: 93 to 99%) and 96% (95%CI: 90 to 99%), respectively. These were not significantly different from those of the composite scale and the clinical algorithm. The four approaches showed almost perfect agreement with each other. CONCLUSIONS: These results suggest that simple qualitative assessment may be useful in clinical practice to help the anesthesiologist in the assessment of gastric contents status and risk of aspiration.

Prevalence and factors associated with high-risk gastric contents in women admitted to the maternity unit for childbirth: a prospective multicentre cohort study.

BACKGROUND: This multicentre prospective observational study sought to determine the prevalence and the factors associated with high-risk gastric contents in women admitted to the maternity unit for childbirth, and to identify the clinical situations in which ultrasound assessment of gastric contents would be most helpful (i.e. when the prevalence of high-risk gastric contents is close to 50%). METHODS: Ultrasound assessments of gastric contents were performed within the first hour after admission to the maternity unit. The prevalence of high-risk gastric contents was calculated and variables associated with high-risk gastric contents were identified using logistic regression analyses. RESULTS: A total of 1003 parturients were analysed. The prevalence of high-risk gastric contents was 70% (379/544; 95% confidence interval: 66-74%) in women admitted in spontaneous labour and 65% (646/1003; 95% confidence interval: 61-67%) in the whole cohort. Lower gestational age, increased fasting duration for solids, and elective Caesarean delivery were independently associated with reduced likelihood of high-risk gastric contents. In women admitted in spontaneous labour and in the whole cohort, the prevalence of high-risk gastric contents ranged from 85% to 86% for fasting duration for solids <6 h, 63%-68% for fasting 6-8 h, 54%-55% for fasting 8-12 h, and 47%-51% for fasting ≥12 h. CONCLUSIONS: Around two-thirds of parturients had high-risk gastric contents within the first hour after admission to the maternity unit. Our results suggest that gastric emptying for solids continues in labouring women, and that gastric ultrasound would be most helpful when fasting duration is ≥8 h.

Esketamine pretreatment during cesarean section reduced the incidence of postpartum depression: a randomized controlled trail.

BACKGROUND: Postpartum depression (PPD) is a common mental disease in postpartum women, which has received more and more attention in society. Ketamine has been confirmed for its rapid antidepressant effect in women with PPD. We speculate that esketamine, an enantiomer of ketamine, pretreatment during cesarean can also reduce the incidence of PPD. METHODS: All the parturients enrolled in the study were randomly assigned to two groups: the esktamine group (0.2 mg/kg esketamine) and the control group (a same volume of saline). All the drugs were pumped for 40 min started from the beginning of the surgery. The Amsterdam Anxiety and Information Scale (APAIS) scores before the surgery, the Edinburgh postnatal depression scale (EPDS) scores at 4 d and 42 d after surgery, the Pain Numerical Rating Scale (NRS) scores at 6 h, 12 h, 24 h and 48 h post-operation were evaluated, as well as the adverse reactions were recorded. RESULTS: A total of 319 parturients were analyzed in the study. The incidence of PPD (EPDS score > 9) in the esketamine group was lower than the control group at 4 days after surgery (13.8% vs 23.1%, P = 0.0430) but not 42 days after surgery (P = 0.0987). Esketamine 0.2 mg/kg could reduce the NRS score at 6 h,12 h and 24 h after surgery, as well as the use of vasoactive drugs during surgery (P < 0.05). The incidences of maternal dizziness (17.0%), blurred vision (5%), illusion (3.8%) and drowsiness (3.8%) in the esketamine group were higher than those of control group (P < 0.05). CONCLUSIONS: Intraoperative injection of esketamine (0.2 mg/kg) prevented the occurrence of depression (EPDS score > 9) at 4 days after delivery but not 42 days. Esketamine reduced the NRS scores at 6 h, 12 h and 24 h after surgery, but the occurrence of maternal side effects such as dizziness, blurred vision, drowsiness and hallucination were increased. TRIAL REGISTRATION: Registered in the Chinese Clinical Trial Registry (ChiCTR2100053422) on 20/11/2021.

The relationship between Iranian women's perception of their birth team's compliance with medical ethics and their perception of labor pain.

BACKGROUND: A safe and satisfactory childbirth experience with the least amount of pain constitutes one of the main domains of reproductive healthcare. The most important aspect of labor pain management is the moral and professional commitment of the health professionals and caregivers involved in creating a pleasant delivery. The present study examines the relationship between Iranian women's perceptions of their birth team's compliance with medical ethics and their perception of labor pain. METHODS: This cross-sectional study was conducted on 200 women opting for natural childbirth. The samples were selected by convenience sampling. Three questionnaires, including a demographic information questionnaire, the perception of labor pain questionnaire, and the medical ethics attitude in vaginal delivery questionnaire, were used to collect data. The data were entered into SPSS 22 and analyzed using correlation coefficient and multiple regression tests. The significance level for data analysis was set as less than 0.05. RESULTS: The results of the regression analysis showed that among the four principles of medical ethics, only the second and third principles (beneficence and non-maleficence) predicted the perception of labor pain (B = -0.267, P < 0.037). Among the different domains of these principles, the areas of giving the necessary information to the mother (B = -0.199, P = 0.001), respecting the mother's privacy (B = -0.194, P = 0.001), interaction with the mother (B = -0.287, P = 0.001) and assurance of fetal health (B = -0.492, P = 0.001) were predictors of labor pain perception score. CONCLUSIONS: Compliance of the birth team with respecting the mother's privacy, having friendly interactions with the mother and giving fetal health assurance to the mother can be a predictor of the mother's decreased perception of labor pain.

Experiences of childbirth care in Lithuania and Romania: Insights from the European Babies Born Better survey.

BACKGROUND: Data on experience and satisfaction of users are essential for improvement of health care, especially in the field of childbirth. The aim of this study was to compare childbirth care experiences in Lithuania and Romania. METHODS: Data derived from the EU Babies Born Better online survey were analyzed. Parturients from Lithuania (N = 373) and Romania (N = 359) who had given birth within the last 5 years were included. Participants were asked to (1) describe the best things in childbirth care and (2) suggest changes in the care received at their birthplace. Qualitative data were analyzed using a previously developed deductive coding framework. RESULTS: In agreement with previous findings from Austria, positive experiences mainly addressed care experienced at an individual level (in particular healthcare practitioners' competence and personality traits) and suggested changes mainly addressed services at birthplace (issues related to infrastructure, information and counseling, and empowerment). Responses not initially included in the coding framework addressed aspects such as informal payment (in both countries), desire for home birth (particularly in Lithuania), or mistreatment of parturients (particularly in Romania). CONCLUSIONS: We conclude that similar trends in childbirth care exist in Lithuania and Romania with regard to parturients' personal experiences and psychosocial needs and that addressing the needs of parturients is important for improving service provision.

Plasmodium infections and associated risk factors among parturients in Jawi district, northwest Ethiopia: a cross-sectional study.

BACKGROUND: Pregnant women have an increased risk of Plasmodium infections and disease. Malaria in pregnancy is a major public health problem in endemic areas. Assessment of the burden and risk factors of malaria in pregnancy across different malaria transmission settings is required to guide control strategies and for malaria elimination. Thus, the current study is generating such evidence from parturient women in northwest Ethiopia. METHODS: A cross-sectional study was conducted among 526 pregnant women admitted to the delivery rooms of selected health facilities in Jawi district, northwest Ethiopia, between November 2021 and July 2022. Data on the socio-demographic, clinical, obstetric, and malaria prevention practices of pregnant women were collected using interviewer-administered questionnaires and from women's treatment cards. Malaria was diagnosed by light microscopy, rapid diagnostic test, and multiplex real-time polymerase chain reaction. Risk factors for malaria were evaluated using bivariable and multivariable logistic regression models. A P-value of < 0.05 was considered statistically significant. RESULTS: Among the examined parturient women, 14.3% (95% CI 11.4-17.5%) had Plasmodium infections. The prevalence of peripheral, placental, and congenital malaria was 12.2% (95% CI 9.5-15.3%), 10.9% (95% CI 8.2-14.1%), and 3.7% (95% CI 2.3-6.1%), respectively. About 90.6% of peripheral and 92% of placental Plasmodium infections were asymptomatic. Plasmodium infection at parturiency was independently predicted by maternal illiteracy (AOR = 2.03, 95% CI 1.11-3.74), primigravidity (AOR = 1.88, 95% CI 1.01-3.49), lack of antenatal care follow-up (AOR = 2.28, 95% CI 1.04-5.03), and history of symptomatic malaria during pregnancy (AOR = 4.2, 95% CI 2.32-7.59). Moreover, the blood group O phenotype was significantly associated with placental malaria among the primiparae. CONCLUSIONS: Overall, asymptomatic Plasmodium infections were prevalent among parturients in northwest Ethiopia. Maternal illiteracy, primigravidity, lack of antenatal care follow-up, and history of symptomatic malaria during pregnancy were the risk factors for malaria during parturiency. Thus, promotion of a healthy pregnancy through ANC follow-up, strengthening malaria prevention and control practices, and screening of malaria in asymptomatic pregnant women are suggested to reduce its burden in pregnancy.

CAT-CBAM-Net: An Automatic Scoring Method for Sow Body Condition Based on CNN and Transformer.

Sow body condition scoring has been confirmed as a vital procedure in sow management. A timely and accurate assessment of the body condition of a sow is conducive to determining nutritional supply, and it takes on critical significance in enhancing sow reproductive performance. Manual sow body condition scoring methods have been extensively employed in large-scale sow farms, which are time-consuming and labor-intensive. To address the above-mentioned problem, a dual neural network-based automatic scoring method was developed in this study for sow body condition. The developed method aims to enhance the ability to capture local features and global information in sow images by combining CNN and transformer networks. Moreover, it introduces a CBAM module to help the network pay more attention to crucial feature channels while suppressing attention to irrelevant channels. To tackle the problem of imbalanced categories and mislabeling of body condition data, the original loss function was substituted with the optimized focal loss function. As indicated by the model test, the sow body condition classification achieved an average precision of 91.06%, the average recall rate was 91.58%, and the average F1 score reached 91.31%. The comprehensive comparative experimental results suggested that the proposed method yielded optimal performance on this dataset. The method developed in this study is capable of achieving automatic scoring of sow body condition, and it shows broad and promising applications.

Development and validation of a facile rapid assessment scale for perinatal venous thromboembolism in puerperium in Chinese women.

BACKGROUND: It is still urgent and challenge to develop a simple risk assessment scale for venous thromboembolism (VTE) in puerperium in Chinese women. METHODS: The study, a retrospective case-control study, was conducted in 12 hospitals in different cities in China. A total of 1152 pregnant women were selected, including 384 cases with VTE and 768 cases without VTE. A logistic regression method was conducted to determine the risk factors of VTE. RESULTS: Age, BMI before delivery, gestational diabetes mellitus, family history (thrombosis, diabetes, cardiovascular disease), and assisted reproductive technology were independent risk factors (P<0.05). The difference between the high-risk group and the low-risk group was statistically significant(P<0.001) with a sensitivity of 0.578, specificity of 0.756, Yuden index o.334, and area under the ROC curve of 0.878. CONCLUSIONS: The age (≥ 35 years), BMI before delivery (≥ 30 kg/m2), gestational diabetes mellitus, family history of related diseases and assisted reproductive technology are more likely to cause VTE after full-time delivery. The simple and rapid assessment scale of VTE in women after full-term delivery has perfect discrimination (P < 0.001), which can be applied to predict the risk of VTE in Chinese full-term postpartum women.

The Parturient Women's Privacy Preservation in the Delivery Rooms: A Qualitative Study.

Introduction: Parturient women's privacy preservation and respectful maternity care (RMC) in delivery room is an important principle in the high quality of midwifery care to achieve maternal satisfaction and positive childbirth experience. Hence, it is essential to make natural vaginal delivery (NVD) a positive experience and increase the mothers' satisfaction. This study aimed to investigate the privacy preservation of parturient women's in the delivery room. Methods: Using conventional content analysis, this qualitative study was conducted from June 2018 to December 2020 at two hospitals and three health centers in Shahroud, Iran. Purposeful sampling was employed and it was continued till data saturation through in-depth interviews with 37 participants. Results: The results of interviews with 21 women with NVD experience and 16 maternity health service providers resulted in the extraction of four themes including physical, spiritual-mental, informational, and social privacy. Conclusion: Various mechanisms were found to promote the privacy and satisfaction of parturient women in the delivery room. They included the necessity continuous education, monitoring about mother's privacy preservation and intervention to improve effective communication skills among staff in delivery rooms.

Esforços expulsivos expiratórios no parto: um cuidado do enfermeiro obstetra / Expiratory expulsive efforts during childbirth: an obstetric nurse's care

O presente relatório tem como objetivo explanar o meu percurso de aprendizagem, apresentando a análise crítica da aquisição e desenvolvimento das competências comuns e especializadas de enfermeiro especialista, no âmbito da Unidade Curricular Estágio com Relatório, inserida no 11º Curso de Mestrado em Enfermagem de Saúde Materna e Obstetrícia, bem como descrever a investigação realizada acerca da utilização dos esforços expulsivos expiratórios (EEE) durante o parto, estabelecendo a necessidade de reflexão relativamente à inclusão desta temática na prática de cuidados do enfermeiro obstetra. As opções metodológicas tiveram por base a prática baseada na evidência e, assentaram numa Scoping Review de acordo com as orientações do Joanna Briggs Institute (2020), onde se pretendeu mapear a evidência científica relevante sobre a temática. A questão de pesquisa foi: "Quais os resultados dos esforços expulsivos expiratórios durante o parto." Os resultados obtidos suportaram o estudo descritivo e transversal desenvolvido no contexto de Bloco de Partos com uma amostra de 21 parturientes, cujos objetivos foram: Descrever a importância do conhecimento e treino durante a gravidez dos EEE para potenciar os contributos desta técnica no período expulsivo; analisar a relação entre a utilização dos EEE, a duração do período expulsivo, a gestão da dor no período expulsivo, a posição adotada, a integridade do períneo após o parto, a satisfação com a experiência de parto e os outcomes neonatais (adaptação do RN à vida extrauterina/Índice de Apgar). Os resultados evidenciaram que ao promover a utilização dos EEE, o enfermeiro obstetra promove o bem-estar, a diminuição da fadiga e a vivência positiva do parto, o que contribui para elevados índices de satisfação com a experiência de parto. As parturientes referiram como fatores relevantes para o sucesso dos EEE a intervenção de apoio e orientação do enfermeiro obstetra e o conhecimento prévio da técnica. Os EEE respeitam o processo fisiológico do parto contribuindo para um parto normal e para uma experiência de parto mais positiva.

The main purpose of this report is to explain my learning path and present the critical analysis of the development of common and specialized skills of specialist nurse, within the Report Curricular Unit, included in the 11th Master Course in Maternal and Obstetrics Nursing, as well to describe the scientific evidence about the use of expulsive exhalation efforts (EEE's) during childbirth, imposing the need for reflection on the inclusion of this theme in the practice of obstetric nurses. The methodological options of this report were founded on evidence-based practice in accordance with the Scoping Review within the guidelines of the Joanna Briggs Institute (2020), where the intention was to map the relevant scientific evidence on the subject. The research question was: "What are the results of expiratory expulsive efforts during childbirth." The results obtained supported the descriptive and cross-sectional study developed in the Labour Ward with a sample of 21 pregnant women in labour, whose aims were: To describe the importance of knowledge and training EEE's during pregnancy to enhance the contributions of this technique in the expulsive period; to analyze the relationship between the use of EEE's and the duration of the expulsive period, pain management in the expulsive period, the position adopted, the integrity of the perineum after delivery, childbirth experience satisfaction and neonatal outcomes (newborn's adaptation to extrauterine life/Apgar score). The results showed that by promoting the use of EEE's, the obstetric nurse promotes well-being, decreased fatigue and the positive childbirth experience, which contributes to high levels of satisfaction with the childbirth experience. The parturient women mentioned that obstetric nurse support and guidance as well as previous knowledge of the technique, were determinant for the EEE's success. The EEE's respect the physiological process of childbirth contributing to a normal childbirth and a more positive childbirth experience.

Influence of blood donation before pregnancy on neonatal birth weight / 中国输血杂志

【Objective】 To explore the influence of maternal blood donation before pregnancy on neonatal birth weight. 【Methods】 A total of 6 428 full-term (gestational age ≥37 weeks) singleton pregnant women in Ningbo Medical Center Lihuili Hospital and Ningbo Women and Children′s Hospital from January 2020 to October 2020 were enrolled in this study. The cumulative whole blood donations before pregnancy were obtained through Alipay software. The relevant data of parturients and their fetuses were collected from electronic medical records. 【Results】 The maternal blood donation rate in Zhejiang Province before pregnancy was 14.69%. The average age of women was 29 (27-32), and the median of cumulative blood donation (except 0 mL) before pregnancy was 300 mL. Univariate analysis showed that there was no significant difference in neonatal gender, neonatal birth weight, proportion of low birth weight infants and proportion of macrosomia among non blood donation group, low blood donation group and high blood donation group (P>0.05). After multiple linear regression analysis, it was found that there was no correlation between blood donation before pregnancy and the neonatal birth weight (B=0.123, 95%CI: -1.013-8.461, P>0.05). Multivariate Logistic regression analysis showed that, compared with the non blood donation group, the occurrence of macrosomia was higher in both the low blood donation group and the total blood donation group (OR=1.366, 95%CI: 1.007-1.766, P<0.05; OR=1.369, 95%CI: 1.019-1.851, P<0.05). 【Conclusion】 Maternal blood donation before pregnancy may not be related to neonatal birth weight, but may be related to the probability of macrosomia in their offspring.
