The evaluation of the antepartum and intrapartum risk factors in predicting the risk of birth asphyxia

Correlation between anesthetic concentration and low Apgar scores in neonates born via Cesarean sections under general anesthesia

OBJECTIVES

This study aimed to compare plasma concentrations of anesthetic drugs administered during Cesarean section with low Apgar score in neonates deliveried under general anesthesia and analyze associated risk factors.

METHODS

Data from 76 neonates undergoing Cesarean section under general anesthesia with blood concentrations of anesthetic drugs were analyzed. A low Apgar score was defined as ≤ 7. Perioperative maternal and neonatal data were collected and analyzed. Neonates were divided into a control group (Group CON, n = 65) and a low Apgar score group (Group LAS, n = 11) based on Apgar score.

RESULTS

There were no significant differences in the plasma concentrations of anesthetic drugs in maternal artery, umbilical vein or umbilical artery blood between the two groups. Risk factors for neonatal low Apgar scores during Cesarean section under general anesthesia were premature delivery (aOR 10.2, 95% CI = 1.8-56.9) and preoperative fetal distress (aOR 9.6, 95% CI = 1.3-69.0). The prediction model was: probability = 1/(e‑Y), Y= -4.607 + 2.318× (premature delivery) + 2.261× (fetal distress) (yes = 1, no = 0). The Hosmer-Lemeshow test showed χ²= 9.587, P = 0.213, and the area under the curve (AUC) was 0.850 (0.670 ~ 1.000). With a cutoff value of 0.695, sensitivity and specificity were 81.8% and 87.7%, respectively.

CONCLUSIONS

There was no correlation between blood concentration of general anesthetic drugs and Apgar score or occurrence of neonatal low Apgar scores. Premature delivery and preoperative fetal distress were identified as independent risk factors for neonatal low Apgar scores after Cesarean section under general anesthesia.

Perinatal outcomes of twin emergency cerclage: comparison with expectant treatment and singleton emergency cerclage

The present study aimed to evaluate the perinatal outcomes and influencing factors in twin pregnancies undergoing emergency cervical cerclage. The present retrospective cohort study included clinical data that were recorded between January 2015 and December 2021 at The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University (China). The study included data from 103 pregnancies (26 twin and 77 singleton pregnancies) that underwent emergency cerclage and 17 twin pregnancies that underwent expectant treatment. The median gestational age of twin emergency cerclage was significantly lower than that of singleton emergency cerclage, but higher than that of expectant treatment (28.5, 34.0 and 24.0 weeks, respectively). The median interval to delivery of twin emergency cerclage was significantly lower than that of singleton emergency cerclage, but significantly higher than that of expectantly treated twin pregnancies (37.0, 78.0 and 7.0 days, respectively).IMPACT STATEMENTWhat is already known on this subject? An important cause of premature birth is cervical insufficiency. Cervical cerclage extends the gestational period of women with cervical insufficiency. According to 2019 SOGC's No. 373-Cervical Insufficiency and Cervical Cerclage, both twin and single pregnancies benefit from emergency cerclage. However, there is minimal information about the pregnancy outcomes of emergency cerclage in twin pregnancies.What the results of this study add? This study shows that the outcomes of pregnancy in twin pregnancies undergoing emergency cerclage were better than that of expectant treatment but worse than that in singleton pregnancies undergoing emergency cerclage.What the implications are of these findings for clinical practice and/or further research? In this study, pregnant women with cervical insufficiency in twin pregnancies can benefit from emergency cerclage, we should treat those pregnant women as early as possible.

Missed Opportunity of Antenatal Care Services Utilization and Associated Factors among Reproductive Age Women in Eastern Hararghe Zone, Eastern Ethiopia: Mixed Methods Study

Background

Despite the enormous advantages of early pregnancy-related problem diagnosis and therapy during prenatal care visits, not all pregnant women begin antenatal care at the proper time. Thus, this study aims to identify factors associated with missed opportunities for antenatal care service utilization among reproductive-age women in Eastern Ethiopia.

Methods

A mixed methods study design (quantitative and qualitative) was conducted in Grawa, Meta, and Haramaya woredas from September 5 to December 5, 2019. The quantitative data were analyzed using SPSS version 25. A multivariable logistic regression analysis model was used to identify the predictors. Statistical software programs based on ATLAS.ti version 8.2 was were used to conduct the thematic analysis of the qualitative data.

Results

Overall, missed opportunities for antenatal care were 15.4% of 95% (12.1, 19.1%). Factors such as maternal age being 15-24 (AOR = 6.9, 95% CI: 2.89-8.81); having a college education (AOR = 0.02, 95% CI: 0.001, 0.42), elementary (AOR = 0.05, 95% CI: 0.002, 0.98), and secondary education (AOR = 0.04, 95% CI: 0.001, 0.88); having five and more parity (AOR = 0.08, 95% CI: 0.01, 0.75); three visits (AOR = 0.10, 95% CI: 0.02, 0.71); those in the first trimester (AOR = 0.02, 95% CI: 0.001, 0.35) and the second trimester (AOR = 0.01, 95% CI: 0.001, 0.26); and get information from a health facility (AOR =0.09, 95% CI: 0.01, 0.67) and traditional birth attendance (AOR = 0.02, 95% CI: 0.001, 0.74) were factors statistically associated with outcome variables.

Conclusions

According to this report, relatively high proportions of pregnant women experienced missed opportunities in antenatal care follow-up. Factors such as maternal age, education, parity, frequency, timing, and media access were statistically significantly correlated with missed antenatal care follow-up. Therefore, all stakeholders should emphasize advocating for and enhancing the benefits of antenatal care; this in turn plays a crucial role in increasing the follow-up of clients for these crucial services. Moreover, health policy implementers need to coordinate their tracking of pregnant women who missed their antenatal care session.

Factors associated with birth asphyxia among term singleton births at two referral hospitals in Northern Uganda: a cross sectional study

Background

Birth asphyxia is one of the leading causes of neonatal mortality worldwide. In Uganda, it accounts for 28.9% of all neonatal deaths. With a view to inform policy and practice interventions to reduce adverse neonatal outcomes, we aimed to determine the prevalence and factors associated with birth asphyxia at two referral hospitals in Northern Uganda.

Methods

This was a cross-sectional study, involving women who gave birth at two referral hospitals. Women in labour were consecutively enrolled by the research assistants, who also attended the births and determined Apgar scores. Data on socio-demographic characteristics, pregnancy history and care during labour, were obtained using a structured questionnaire. Participants were tested for; i) malaria (peripheral and placental blood samples), ii) syphilis, iii) white blood cell counts (WBC), and iv) haemoglobin levels. The prevalence of birth asphyxia was determined as the number of newborns with Apgar scores < 7 at 5 min out of the total population of study participants. Factors independently associated with birth asphyxia were determined using multivariable logistic regression analysis and a p-value < 0.05 was considered statistically significant.

Results

A total of 2,930 mother-newborn pairs were included, and the prevalence of birth asphyxia was 154 [5.3% (95% confidence interval: 4.5- 6.1)]. Factors associated with birth asphyxia were; maternal age ≤ 19 years [adjusted odds ratio (aOR) 1.92 (1.27–2.91)], syphilis infection [aOR 2.45(1.08–5.57)], and a high white blood cell count [aOR 2.26 (1.26–4.06)], while employment [aOR 0.43 (0.22–0.83)] was protective. Additionally, referral [aOR1.75 (1.10–2.79)], induction/augmentation of labour [aOR 2.70 (1.62–4.50)], prolonged labour [aOR 1.88 (1.25–2.83)], obstructed labour [aOR 3.40 (1.70–6.83)], malpresentation/ malposition [aOR 3.00 (1.44–6.27)] and assisted vaginal delivery [aOR 5.54 (2.30–13.30)] were associated with birth asphyxia. Male newborns [aOR 1.92 (1.28–2.88)] and those with a low birth weight [aOR 2.20 (1.07–4.50)], were also more likely to develop birth asphyxia.

Conclusion

The prevalence of birth asphyxia was 5.3%. In addition to the known intrapartum complications, teenage motherhood, syphilis and a raised white blood cell count were associated with birth asphyxia. This indicates that for sustained reduction of birth asphyxia, appropriate management of maternal infections and improved intrapartum quality of care are essential.
