Cross-sectional study on the obstetric performance of primigravidae in a teaching hospital in Lagos, Nigeria

Proportion and Associated Factors of Nonreassuring Fetal Heart Rate Patterns in Finote Selam Primary Hospital, North West Ethiopia

Introduction

Nonreassuring fetal heart rate patterns (NRFHRP) suggest fetal conciliation or a deteriorating ability to handle the stress of labor. Nearly half of stillbirths occurring worldwide are due to hypoxia which is primarily manifested by NRFHRP. Hence, this study assessed the proportion and associated factors of NRFHRP in the Finote Selam primary hospital, North West Ethiopia.

Methods

An institution-based retrospective cross-sectional study was conducted from March 1 to April 1, 2019, on 364 charts of mothers who gave birth from January 2017 to January 2018 at the Finote Selam primary hospital. A computer-based simple random sampling technique was used to select charts. A secondary data was collected using a structured questionnaire adapted from different literatures. The data was entered and analyzed using Epi Info version 7 and Statistical Package for the Social Sciences (SPSS) version 23.0. Binary logistic regression was executed, and all explanatory variables with p value < 0.2 were entered into multivariable logistic regressions. Multivariable logistic regression was used to control the effect of confounding variables and to identify factors affecting NRFHRP. Odds ratios with 95% confidence intervals were computed, and statistical significance was declared if p < 0.05.

Result

Out of 364 total deliveries, NRFHRP was detected on 55 (15.1%) fetuses, and the commonest NRFHRP detected was bradycardia 44 (80%). Most NRFHRP (38.18%) occurred on the deceleration phase of labor. There was no identified possible cause for NRFHRP on 34.5% of cases. Referral from nearby health institutions [AOR = 2.832 (95% CI 1.457, 5.503)], primigravida [AOR = 2.722 (95% CI 1.377, 5.381)], augmentation of labor [AOR = 3.664 (95% CI 1.782, 7.534)], and meconium-stained amniotic fluid [AOR = 6.491 (95% CI 3.198, 13.173)] were significantly associated with NRFHRP.

Conclusion

The proportion of NRFHRP is high. Referral from nearby health institutions, primigravida mothers, augmentation of labor, and meconium-stained amniotic fluid were significantly associated with NRFHRP. Implementing a better referral link and close monitoring during follow-up could minimize NHFHRP.

[Factors associated with first pregnancy in women who gave birth in a maternity hospital in Antananarivo: a retrospective cohort study]

Introduction

Il y a très peu de littératures africaines et Malgaches concernant les détails sur les facteurs de risques qu'encourent les primigestes en général. Le but de notre étude est de déterminer les facteurs de risques potentiels associés à une première grossesse.

Méthodes

Une étude cohorte rétrospective a été menée auprès des femmes primigestes et multigestes de l'hôpital Pavillon sainte Fleur entre Octobre 2014 et Décembre 2016. Les risques relatifs étaient ajustés après contrôle avec les caractéristiques sociodémographiques.

Résultats

Les primigestes étaient beaucoup plus exposées à un travail prolongé de plus de 12h (RRa = 2,28; IC 95% 1,74-3,00), à une césarienne en urgence (RRa = 1,47; IC 95% 1,35-1,60) et à une épisiotomie (RRa = 2,98; IC 95% 2,61-3,40). Leurs enfants étaient plus susceptibles de présenter des signes de souffrance fœtale avec anomalie du rythme cardiaque fœtale au cours de la phase de travail (RRa = 1,96; IC 95% 1,45-2,65) et un risque accru d'être admis dans une unité de soins intensifs après l'accouchement (RRa = 2,08; IC 95% 1,25-3,45).

Conclusion

Les complications survenues pendant le travail auraient exposé les primigestes à d'autres risques en cascades sur l'issue de leurs accouchements et sur la santé de leurs enfants. La prise en charge des primigestes nécessiterait, de la part des personnels médicaux, une attention particulière sur la durée de la phase de travail.

[Childbirth among primiparous women in Lubumbashi: maternal and perinatal prognosis]

INTRODUCTION

Childbirth in primiparous women is associated with many complications and, therefore, primiparous women are considered high risk due to maternal and fetal concerns. This study aims to determine birth rate in primiparous women in our environment, to identify factors associated with delivery by cesarean section and to assess maternal and perinatal morbi-mortality from childbirth in primiparous women living in Lubumbashi.

METHODS

We conducted a cross-sectional, analytical study of singleton births in 10 referral maternity hospitals in Lubumbashi over the period December 2013-May 2014. Primiparous births were compared to multiparous births. Maternal sociodemographic parameters as well as maternal and perinatal morbi-mortality were analyzed. The odds ratio and its confidence interval were calculated. Threshold significance level was set at p < 0.05.

RESULTS

Primiparity rate was 19.9%. Compared to multiparous births, primiparous births were mainly observed in adolescents (OR=11. 27, (7.98-15.91)), in students (OR = 5.61 (3.33-9.45)) and in women living alone (OR=7.62 (4.36-13.30)). Risk factors associated with delivery by cesarean section in primiparous women included obstetric evacuation (OR = 9.69 (4.75-19.74)), the lack of prenatal monitoring (OR=2.57, (1.32-5.01)), size ≤ 150 cm (OR = 2.42 (1.04-5.65)), uterine height > 34 cm (OR = 2.33 (1.32-4.10)) and malpresentation (OR = 6.37 (2.92-13.87)). With regard to maternal prognosis, we observed that high blood pressure (OR = 1.91 (1.32-2.74)), malpresentation (OR = 1.95 (1.16-3.17)), oxytocin use (OR = 2.03 (1.64-2.52)), cesarean section (OR = 2.04 (1.47-2.83)), episiotomy (OR=11.89 (8.61-16.43)) and eclampsia (OR = 4.21 (1.55-11.44)) were significantly associated with primiparity. The rates of low 5th minute Apgar score (OR = 1.55 (1.03-2.32)) and of deaths occurred during early neonatal period (OR=1.80 (1.08-2.98)) were significantly higher in primiparous women than in multiparous women.

CONCLUSION

This study shows that primiparous birth is a problem in Lubumbashi. Hence improvement in mother-child care during primiparous childbirth includes the development of protocols for adequate management of childbirths.
