Abstract
OBJECTIVE: To determine maternal/neonatal complications and outcome in patients with multiple repeat cesarean sections (CSs).
STUDY DESIGN: A retrospective case-control study of 144 pregnant women with cesarean sections was compared with a control group of 288 women having 2-3 cesarean sections for maternal, operative and neonatal complications.
RESULTS: The study patients had longer operating times (p = 0.0001) due to severe adhesions (p = 0.0005), with increased blood loss and blood transfusion (p = 0.0001). Rupture of the uterus (p = 0.0015), placenta previa (p=0.0372), gestational age at delivery (p < 0.0002), preterm birth (p = 0.0497) and Apgar scores <7 at 5 minutes (p = 0.0140) were significant in the study group. There was no significant difference of placenta accreta, bladder and bowel injury, cesarean hysterectomy, wound infection and postoperative pyrexia between the 2 groups. Among the neonates of the 2 groups, NICLI admissions, small-for-gestational-age birth weights, large-for-gestational-age birth weights and perinatal mortality were similar. No mother died in the series. The incidence of a single major complication was higher in women with 4 cesarean deliveries (p = 0.0011).
CONCLUSION: Repeated CS increases the risk of uterine rupture and intraoperative complications, making these patients a high -risk group. No absolute upper limit for the number of repeat cesarean deliveries can be given. Patients must be informed of the risks of multiple CSs and encouraged to have tubal ligation.
