Features during labor in women with chronic hepatitis B
AIM. To examine the course of labor in women with chronic hepatitis B. METHODS. The course of labor was studied in 391 female patients with chronic viral hepatitis B, included in the study group (mean age 22.7±2.5 years), who delivered off in the National Maternity Hospital (Bishkek). The control group included 59 healthy women in labor (mean age 22.5±1.3 years). RESULTS. The vast majority of patients - 53 (89.8%) of the control group and 328 (83.9%) of the study group - had delivered off at term. Post-term births were registered in both groups. Operative delivery by cesarean section was performed in 13.0% of chronic viral hepatitis B cases - by 4.5% higher compared to control group. In the study group, planned cesarean section was performed in 21 (5.4%) patients, the main indication was burdened obstetric history - in 8 (2.0%) patients; 5 (1.3%) patients had multiple indications. Emergency operations were conducted in 30 (7.7%) patients. Indications were premature rupture of membranes - 15 (3.8%) of cases, fetal hypoxia during labor and multiple indications - 10 (2.6%) cases each. The average blood loss at cesarean section in the group of patients with chronic viral hepatitis B was 870±15.2 ml, compared to 700±10.2 ml in the control group, which can be associated with low coagulation seen in hepatitis. Comparative analysis of the complications rate in the control group revealed that delayed rupture of membranes was the most frequent - 11 (18.6%) cases, followed by intrauterine fetal hypoxia - 5 (8.5%) cases, early postpartum bleeding - 4 (6.8%) cases, hypertensive disorders at labor and retained placenta - 3 (5.1%) cases each. In the group with chronic viral hepatitis B, premature rupture of membranes occurred in 51.5% of cases, (relative risk 2.8). Early postpartum bleedings were seen in 38.9% of the cases at the main group (relative risk 5.7). CONCLUSION. The above data gives us every reason to include women with chronic viral hepatitis B at high-risk group for possible bad pregnancy and childbirth outcomes both for the mother and the fetus.
