Brief summary

The aim of this research work is to assess the impact of a single preoperative dose of buccal misoprostol in reducing blood loss during abdominal fibroid surgery.

Detailed description

This is a trial of women undergoing fibroid surgery at a university-affiliated tertiary care center. Eligible participants will be randomized to receive preoperative 400ucg buccal (under the tongue) misoprostol or placebo on the basis of total fibroid volume, location, parity. Intra-operative blood loss will be compared between groups.

Interventions

DRUGMisoprostol

25 patients undergoing abdominal myomectomy operation will receive two tablets of misoprostol (400 mcg) buccally one hour before the operation.

DRUGPlacebo

25 patients undergoing abdominal myomectomy operation will receive two tablets of Vitamin B6 (100mg) buccally one hour before the operation.

Inclusion criteria

* Patients presenting for abdominal myomectomy with documented uterine fibroids on pelvic imaging (pelvic ultrasound or MRI) within in last 12 months * Age ≥ 18 years and ≤ 50 years * Pre-operative hemoglobin \>8 g/dl * Willing to have buccal administration of misoprostol or a placebo at least one hour pre-procedure. * Ability to understand and the willingness to sign a written informed consent. * Admissible medical/surgical history * Can be previously treated with Depo-Lupron, Depo-Provera, or Oral Contraceptive pills * Intraoperative use of vasopressin and uterine tourniquet is permissible * Can have had prior Cesarean delivery

Exclusion criteria

* Patients who have had a prior abdominal myomectomy * Post-menopausal women * Patients with known bleeding/clotting disorders * Patients with a history of gynecologic malignancy * History of allergic reactions attributed to compounds of similar chemical or biologic composition to misoprostol * Any cases converted to abdominal hysterectomy or other additional elective surgical procedures performed at time of abdominal myomectomy will be excluded from data analysis * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

Pre-assignment details

Forty-seven patients enrolled in the study by signing the informed consent form. However, due to the premature closure, not all participants had the opportunity to undergo the intended intervention. Of these, 39 participants successfully completed the intervention, while 8 participants could not undergo the intervention as planned.
