Abstract
Objective: Termination of second trimester pregnancy is unique obstetric contest due to its difficulty and risky especially if the condition is associated with prior Caesarean deliveries. Aim of the work: To compare the safety and efficacy of two regimens for termination of the second trimester pregnancy in ladies with scarred uterus by prior Caesarean deliveries either by using sublingual and vaginal misoprostol or sublingual misoprostol in a combination with intra cervical Foley’s catheter. Patients and methods: 163 pregnant ladies with second trimester demise pregnancy at14-24 gestational weeks in scarred uterus (≥ one cesarean sections) participated in this prospective randomized comparative study which was performed in obstetric emergency unit in Zagazig University Hospitals, Egypt from June 2019 to May 2020. 140 patients only far-reached the trial through termination of the pregnancy via induction of abortion by sublingual and vaginal misoprostol Group 1 (GI) or Foley’s catheter with vaginal misoprostol Group 2 G (II). Whichever of those methods sustained for 48 hours else the fetus expulsed formerly .Outcomes was determined by comprehensive expulsion of fetus and placenta, Induction Abortion interval, Incidence of side effects, requirement for surgical intervention and complications" rate. Results: The demographic criteria of both groups revealed no significant difference (P-value>0.05). The mean (SD) of Induction to abortion interval (hours) in GI was significant longer than in G II (51.07±23.84, 45.20±31.28) respectively with (P- value 0.021). Total dose (μg) of misoprostol used in GI (1100.72±23.54) was higher than G II (645.35± 322) with p value 0.001. Admission-termination hospitalization (days) was significant longer in G I (4.11±1.02) than in G II (2.371±1.98) with P value 0.004. No significant difference as regard occurrence of adverse effects between both groups except the incidence of fever (17.1%) in G I and (5.7%) in G II with P value 0.01. Success rate in GI and G II were (80%, 95%) respectively with P-value 0.01. Incomplete expulsion was higher in GI (14.3%) in comparison with G II (4.2%) with P value 0.04. Incidence of haemorrhage was significant higher in G II than in GI P value 0.03. No significant differences between both groups as regard incidence of rupture uterus or occurrence of infection. Conclusion: Practice of inserting Foley’s catheter through cervix with misoprostol sublingually for termination of mid-trimester pregnancy in preceding uterine scar(s) is efficient, inexpensive and safe procedure.
