Objective: The aim of this study is to determine the efficacy of preoperative misoprostal in reducing hemorrhage during abdominal myomectomy.

Study Design: Prospective comparative randomized double blinded

Place and Duration: Conducted at DHQ Zanana hospital Dera Ismail Khan for one year duration from January 2019 to December 2019.

Methods: Total 100 patients underwent abdominal myomectomy were presented in this study. Patients were aged between 18-45 years of age. Patients’ detailed demographics including age, body mass index and parity were recorded after taking informed written consent. Patients were categorized equally into two groups, I and II. Group I had 50 patients and received single dose 400 micrograms of misoprostol transrectally one hour preoperatively and group II had 50 patients and received 2-tablets of placebo preoperatively. Outcomes intraoperative blood loss, blood transfusion, hysterectomy and complications among both groups were assessed. Complete data was analyzed by SPSS 23.0 version.

Results: Mean age of the patients was 32.16±9.44 with mean BMI 26.07±10.44 kg/m2. There were no significantly difference among age and body mass among both groups. 60 Patients had 0 parity, 30 patients had parity 1 and the rest were had parity 2. Mean pre-operative hemoglobin in group I was 13.64±8.55 and post-operative was 9.88±8.55 and in group II mean pre-operative hemoglobin was 13.55±8.55 and post-operative was 9.12±5.55. Mean intraoperative blood loss in group I was 388.17±37.18 ml and in group II was 501.16±17.64 ml. Post-operatively blood transfusion in group I was among 2(4%) cases and 3 (6%) in group II. Mean hospital stay in group II was greater as compared to group I. Nausea, vomiting and shivering were the complications found in this study.

Conclusion: We concluded in this study that the use ofmisoprostol preoperatively during abdominal myomectomy was effective safe and useful in reduction of intraoperative blood loss and post-operatively blood transfusion among patients.
