Induction of labour by amniotomy combined IV with syntocinon and IV syntocinon alone

Abstract

Introduction: Induction of labour is artificial initiation of uterine contractions after the period of viability, with the intention of accomplishing delivery prior to onset of spontaneous labor. Oxytocin is the commonest induction agent used worldwide. It has been used alone, in combination with amniotomy or following cervical ripening with other pharmacological or non-pharmacological methods. Aim: The present study is to compare the results of induction of
labour by amniotomy combined intravenous with syntocinon and intravenous syntocinon alone. Materials and methods: This Study carried out over a period of six months. Patients with a definite indication for induction were chosen from ante-natal ward and studied in two groups. In group – I, 60 patients who were induced by artificial rupture of membranes combined with intravenous oxytocin included and in group – II, 30 patients who were induced by oxytocin alone included. Results: Induction delivery interval was shorter in the group - I with a mean of 4 hours and 10 minutes ( range being 2 hours 50 minutes to 10 hours 30 minutes ) compared to group - II whose mean duration was 21 hours 36 minutes ( range being 5 hours 30 minutes to 33 hours ). Among the 60 patients in group – I, 44 had spontaneous vaginal delivery, 10 had out-let forceps delivery and 6 subjects underwent caesarean section. By contrast, of the 30 patients in group - II 19 delivered spontaneously, 3 patients has out-let forceps delivery and 8 subjects underwent caesarean section. Mean latent period and IDI are shorter in group - I as compared to group - II.In both groups Post dated pregnancy was the commonest indication of induction followed by gestational hypertension, essentia hypertension and intrauterine growth retardation. Failure of induction and fetal distress is much lower in Group- I Conclusion: The present concluded that that the induction method with amniotomy and syntocinon combined is more efficacious and safer than one with syntocinon alone.
