Effect of premature rupture of membranes on the maternal and fetal prognosis during childbirth at the gynecology-obstetrics department of the Matam Communal Medical Center, Conakry, Guinea

Background: Premature rupture of membranes (RPM) is defined by rupture of the amnion and chorion before entering labor within 24 hours leading to vaginal discharge of amniotic fluid without uterine contractions. Objective of this study was to improving the management of premature Ruptures of the membranes received in the service.Methods: This was a descriptive and analytical prospective study lasting six months from January 1 to June 30 2016.Results: During the study period, we collected 108 cases of RPM out of 1543 deliveries, representing a hospital frequency of 7%. RPM had more frequently concerned pregnant women aged 25-29 (37.04%), housewife (37.03%), primiparous (45.37%) and referral (52.78%). 95.37% were single pregnancies with cephalic presentation (80%) received between 37-42 weeks (84.26%). Management mainly consisted of antibiotic prophylaxis (100%), fetal pulmonary maturation and childbirth. The vagina was the main mode of delivery (62.04%). The maternal prognosis was dominated by chorioamnionitis (12.96%). The fetal one was made up of respiratory distress (40.71%) and prematurity (12.39%).Conclusions: RPM is frequent at the Matam municipal medical center. It is essential for its prevention to ensure health education of the population in general and genital hygiene in particular, to make a coherent prenatal follow-up while putting a particular accent on the detection and the treatment of genital infections

Acceptability of contraceptive implants at the maternity ward of the Matam Communal Medical Center

Background: World Health Organization (WHO), defines contraception as "the use of agents, devices, methods or procedures to decrease the likelihood of conception or avoid it". In Africa, only 24% of women of childbearing age have access to a modern contraceptive method. The objective of the study was to determine the frequency of use of the contraceptive implant, to describe the socio-demographic characteristics of the users, to identify the reasons for the choice of the method and to assess the degree of satisfaction of the clients.Methods: The study was conducted at the Matam Communal Medical Center on level 2 of the health pyramid in Guinea. This was a 12-month cross-sectional, descriptive and analytical study (June 2017 to May 2018), including all women admitted for desire for contraception and who agreed to choose the implant as a contraceptive method.Results: The study involved 512 clients. The proportion of female users was 26.21%. The average age was 27.8 years, the main users were women of liberal trade, married, multiparous. The main reasons for choice cited by clients were the effectiveness and long duration of action of the method, i.e. 35.2% and 30.9% respectively. The majority of providers of the method were represented by midwives (73.3%) and the degree of client satisfaction with the method was 97%.Conclusions: The implant is a long-acting method of contraction. It is frequently used at the Communal Medical Center of Matam. Its efficient use would involve effective counselling

Management of pre-eclampsia and its complications in the department of gynecology and obstetrics at Donka national hospital Conakry, Guinea

Background: Vascular-renal syndrome, also known as pre-eclampsia, is a condition specific to pregnancy, usually occurring in the last trimester of pregnancy. Pregnant women are sometimes at risk of unpredictable obstetrical complications such as: hemorrhage, kidney failure, HELLP syndrome, sometimes even brain damage requiring prompt care and multidisciplinary collaboration. Vascular-renal syndromes are the third leading cause of maternal death and also the world's leading cause of perinatal death. Objectives of this study were to analyse the management of vascular-renal syndromes. Calculate their frequency, describe the sociodemographic characteristics of patients, describe the clinical and biological signs of patients, evaluate the maternal-fetal prognosis.Methods: The study was conducted in the department of obstetrics and gynecology of Donka National Hospital. It was a prospective, descriptive, cross-sectional, 6-month study from March 1st to August 31st, 2015, of pregnant women with pre-eclampsia.Results: The study included 217 cases of pre-eclampsia out of a total of 3054 patients, i.e. a proportion of 7.10%. The proportion of pre-eclampsia was high in patients aged between 15 and 19 years, housewife, married, primary. The predisposing factors were primigestitis, obesity and twinkling. The clinic was dominated by headaches and visual disturbances. Severe preeclampsia in 78.49%, eclampsia in 21.65% or simple hypertension in 1.75%. Maternal and fetal complications were dominated by eclampsia 26.26%, PPH (2.63%), eclamptic coma (0.46%), acute fetal distress 27.19%, and fetal death in utero (11.40%). In order to improve maternal and fetal prognosis it is necessary to provide multidisciplinary care, which unfortunately is not always available in our context.Conclusions: Obstetric emergency is a frequent situation for which a better management would improve the maternal-fetal prognosis

NUMERICAL INVESTIGATIONS OF FORCED CONVECTION FROM RECTANGULAR COILED PIPES

ABSTRACT Investigations are done to numerically study forced convective heat transfer from the flow inside a rectangular coiled pipe, as micro-scale heat exchange device with staggered arrangement, to the external flow around the pipe. The commercial CFD software Fluent 6.0 is used as the solver. The problems considered were three-dimensional laminar flow of the refrigerant R141B through the tube and turbulent air flow exterior to the tube. The studied coiled pipe was composed of four rows among which two rows were encompassed in a large rectangular coil and the other two were in an inner smaller rectangular coil. The results showed remarkable differences in the flow behavior and heat transfer for different rows of tubes. The secondary flow in the tubes bends of the larger rectangular coil is very weak compared to that of the inner rectangular coil. Better heat transfer process occurred through the tubes of the second row where the higher values of the fluid temperatures were observed in the pipe. The results showed the effects of the straight tubes inclination angle on the flow behavior in rectangular coiled pipes. The shape of the secondary flow is changed from a couple of vortices in the case of smaller angle (α =9 o ) to a single vortex in the case of larger angle (α =45 o ). The results also showed the rotation of the maximum axial velocity due to the increase in the straight tubes inclination angles. The results are in good agreement with previous numerical and experimental works on laminar flow in helical coil pipe

Clinical presentation and improvised management of neonatal pneumothorax in the setting of a low-resource country: Conakry, Guinea

Two neonates were presented at the Neonatology Department of the Institute of Child Nutrition and Health in Conakry, Guinea, with tension pneumothoraces as confirmed by chest X-ray. They were initially managed with needle thoracentesis but required continuous thoracic drainage. Due to scarce resources in the public health sector, no prepacked and dedicated pleural drainage systems were available as is the case in many developing countries. Therefore, we fabricated an improvised underwater seal drain out of a plastic infusion bottle and a Heimlich valve out of a vicryl fingerstall. Both devices have shown to be effective. Pneumothorax is a common and potentially life-threatening disease in neonates that often requires prompt treatment. This case series demonstrates how tension pneumothorax in two newborns was successfully managed by improvising different chest drainage systems. The depicted techniques shall serve as an instruction manual to healthcare professionals working in low-resource settings and facing similar challenges

"Assessing Today for a Better Tomorrow": An observational cohort study about quality of care, mortality and morbidity among newborn infants admitted to neonatal intensive care in Guinea

BACKGROUND Neonatal mortality in Guinea accounts for about 30% of all fatalities in children younger than five years. Countrywide, specialized neonatal intensive care is provided in one single clinic with markedly limited resources. To implement targeted measures, prospective data on patient characteristics and factors of neonatal death are needed. OBJECTIVE To determine the rates of morbidity and mortality, to describe clinical characteristics of admitted newborns requiring intensive care, to assess the quality of disease management, and to identify factors contributing to neonatal mortality. METHODS Prospective observational cohort study of newborns admitted to the hospital between mid-February and mid-March 2019 after birth in other institutions. Data were collected on maternal/prenatal history, delivery, and in-hospital care via convenience sampling. Associations of patient characteristics with in-hospital death were assessed using cause-specific Cox proportional-hazards models. RESULTS Half of the 168 admitted newborns underwent postnatal cardiopulmonary resuscitation. Reasons for admission included respiratory distress (49.4%), poor postnatal adaptation (45.8%), prematurity (46.2%), and infections (37.1%). 101 newborns (61.2%) arrived in serious/critical general condition; 90 children (53.9%) showed clinical signs of neurological damage. Quality of care was poor: Only 59.4% of the 64 newborns admitted with hypothermia were externally heated; likewise, 57.1% of 45 jaundiced infants did not receive phototherapy. Death occurred in 56 children (33.3%) due to birth asphyxia (42.9%), prematurity (33.9%), and sepsis (12.5%). Newborns in serious/critical general condition at admission had about a fivefold higher hazard to die than those admitted in good condition (HR 5.21 95%-CI 2.42-11.25, p = <0.0001). Hypothermia at admission was also associated with a higher hazard of death (HR 2.00, 95%-CI 1.10-3.65, p = 0.023). CONCLUSION Neonatal mortality was strikingly high. Birth asphyxia, prematurity, and infection accounted for 89.3% of death, aggravated by poor quality of in-hospital care. Children with serious general condition at admission had poor chances of survival. The whole concept of perinatal care in Guinea requires reconsideration
