RESUMEN
OBJECTIVE: To determine the trends of instrumental vaginal delivery (IVD) and cesarean section (CS) at the Lagos University Teaching Hospital (LUTH), Nigeria, over 16 years, from 2002 to 2017. METHODS: A retrospective cross-sectional study. The case records of all women who had IVD and CS during the study period were reviewed. The trends in the IVD and CS rates were evaluated using join point regression modeling. The average annual percent change (AAPC) and annual percent change (APC) with associated 95% confidence interval of segmental trends were calculated. RESULTS: The overall IVD rate was 1.36%. Vacuum delivery rate was higher than forceps (0.79% vs 0.57%). The CS rate was 44.9 per 100 deliveries; the rate increased by about 3.7% per annum. CS rates were 7.1-89.9 times the IVD rates within the study period. The number of IVDs performed in the hospital declined by about 83.02%, from 53 cases in 2002 to nine cases in 2017. Forceps delivery declined at a faster rate than vacuum delivery between 2002 and 2017 (AAPC for forceps: -12.6% [-17.5 to -7.5], P < 0.001 vs AAPC for vacuum: -6.2% [-14.3 to 2.7], P = 0.200). The commonest indication for IVD was prolonged second stage of labor (47/162, 29.01%) and shortening of the second stage of labor for maternal conditions (47/162, 29.01%). CONCLUSION: IVD rates are low and declining at LUTH. There is need to train accoucheurs on the safe use of IVDs to potentially reduce the CS rate.
RESUMEN
BACKGROUND: Sickle cell anemia is the commonest hemoglobinopathy in pregnant Nigerian women, and cardiac manifestations are a significant feature of the disease especially in pregnancy. Pregnant women with sickle cell anemia are at high risk of morbidity and mortality and cardiac dysfunction in them increases this risk and may compromise their post-partum health. OBJECTIVE: To evaluate the cardiac size and function in women with sickle cell anemia (HbSS) during late pregnancy and postpartum. METHODOLOGY: This was a longitudinal comparative study in which 40 women, consisting of 20 pregnant HBSS and 20 pregnant HBAA women controls, were recruited. Echocardiography was performed in the third trimester of pregnancy and 6 weeks postpartum. RESULTS: There was a decrease in the mean left atrial diameter (p < .001), left ventricular diameter in diastole (p = .041), and left ventricular mass (p = .004) of HBSS women in the postpartum period compared to their antepartum state. In contrast, there was no significant difference in most cardiac dimensions of pregnant vs postpartum HBAA women. There was no significant change in cardiac function in the pregnant vs postpartum states in both study groups. There were significant differences in cardiac size but not function when comparing HBSS and HBAA women in pregnancy and postpartum. CONCLUSION: Changes in cardiac size of sickle cell women in pregnancy does not appear to affect cardiac function during pregnancy and in the puerperium, suggesting that the increased size may purely be a response to their chronic anemic state. Studies following women up for longer periods including those with co-morbidities are recommended.
