Open Journal of Obstetrics and Gynecology 2023年第11期13卷 1849-1858页

作者： ibrahima conté ibrahima Sylla Ousmane Baldé Aboubacar Fodé Momo Soumah Abdourahamane Baldé Oumou Hawa Bah ibrahima Sory Baldé Abdoulaye Bademba Diallo Telly Sy Department of Obstetrics and Gynaecology Ignace Deen National Hospital University Hospital Centre Conakry Guinea Department of Obstetrics and Gynaecology Donka National Hospital University Hospital Centre Conakry Guinea Department of Obstetrics and Gynaecology Labé Regional Hospital Labé Guinea

Introduction: Obstetric emergencies are clinical situations of a serious nature, often dangerous, which develop unexpectedly, threatening the vital prognosis of the mother and/or foetus in the short term. The aim of this study was to contribute to a review of obstetric emergencies at the Labé Regional Hospital maternity unit. Methods: This was a prospective descriptive and analytical study conducted over a period of 6 months in the maternity unit of the Labé Regional Hospital. It concerned all patients admitted to the department for obstetric emergencies. Results: Obstetric emergencies accounted for 20% of obstetric admissions. The mean age of the patients was 25.12 ± 7.15 years, with extremes of 14 and 45 years. The patients were housewives (42.52%), 42.86% did not attend school and 77.41% were from urban areas. The poor were the most numerous (43.52%). The ambulance was the means of transport in only 9% of cases. Acute foetal distress, pre-eclampsia, bony dystocia and post-partum haemorrhage were the most common types of emergency in our series, with frequencies of 27.57%, 22.59%, 17.94% and 10.63% respectively. The risk factors identified were age, origin, gestational age and the state of the maternal pelvis. Conclusion: Obstetric emergencies are frequent in our study site and represent a major concern for patients, providers and the community alike. In order to reduce the frequency of obstetric emergencies, young girls should be enrolled in school, the legal age for marriage should be respected, quality antenatal care should be provided in basic health facilities, and proper planning and spacing of pregnancies should be implemented.

Neonatal Mortality Associated with the Referral of Low Birth Weight Newborns to the Institute of Child Nutrition and Health (INSE)

引用

Open Journal of Pediatrics 2019年第4期9卷 287-295页

作者： Diallo ibrahima Sory Diallo Sory conté N’fanly Diawara ibrahima Bah Elhadj Mamoudou Cissé Moussa Matthias Roth Kleiner Sy Telly Pediatrics Chair Gamal Abdel Nasser University Conakry Guinea Institute of Nutrition and Child Health Conakry Guinea Gyneco-Obstetrics Chair Gamal Abdel Nasser University Conakry Guinea Department of Women Mother and Child Lausanne Switzerland

The objective of this study was to identify risk factors and study the causes of neonatal mortality of LBW newborns referred to the Institute of Nutrition and Child Health. Material and Methods: This is a prospective descriptive and analytical study from March 1 to August 31, 2015, involving 250 newborns referred to the Neonatology Department of the Institute of Child Nutrition and Health (INSE). Results: During our study period, we recorded 1169 newborns, 250 of whom were referred, representing a referral frequency of 21.38%. The overall mortality rate for transferring newborns was 46.8%. Risk factors associated with neonatal mortality were gravidity (p = 0.0019), parity (p = 0.0323), occupational activities requiring physical effort (p = 0.0257), birth weight (p = 0.0008) and prematurity (p = 0.0039). Conclusion: Neonatal mortality associated with referrals is a major health problem in developing countries. There is currently no doubt that it is possible to significantly reduce perinatal mortality and morbidity rates by organizing the identification of “mother-child” couples at risk, to refer them intently to centres better equipped with technical and human resources to care for them.
