Abstract:

Objective

To synthesize evidence on the most effective pharmacological interventions for bleeding reduction during open and minimally invasive myomectomy.

Design

Systematic review and network meta-analysis of randomized controlled trials (RCTs).

Setting

Not applicable.

Patients

Trials assessing efficacy of pharmacological interventions during different types of myomectomy.

Interventions

Misoprostol, oxytocin, vasopressin, tranexamic acid (TXA), epinephrine, or ascorbic acid.

Main Outcome Measures

Intraoperative blood loss and need for blood transfusion.

Results

The present review included 26 randomized control trials (RCTs) (N = 1627). For minimally invasive procedures (9 RCTs; 474 patients), network meta-analysis showed that oxytocin (mean difference [MD] −175.5 mL, 95% confidence interval [CI] −30.1.07, −49.93), ornipressin (MD −149.6 mL, 95% CI − 178.22, −120.98), misoprostol, bupivacaine plus epinephrine, and vasopressin were effective in reducing myomectomy blood loss, but the evidence is of low quality. Ranking score of treatments included in subgroup analysis of minimally invasive myomectomy showed that oxytocin ranked first in reducing blood loss, followed by ornipressin. For open myomectomy (17 RCTs; 1,153 patients), network meta-analysis showed that vasopressin plus misoprostol (MD −652.97 mL, 95% CI − 1113.69, −174.26), oxytocin, TXA, and misoprostol were effective; however, the evidence is of low quality. Vasopressin plus misoprostol ranked first in reducing blood loss during open myomectomy (P = .97).

Conclusion

There is low-quality evidence to support uterotonics, especially oxytocin, and peripheral vasoconstrictors as effective options in reducing blood loss and need for blood transfusion during minimally invasive myomectomy. Oxytocin is the most effective intervention in minimally invasive myomectomy. For open myomectomy, a combination of uterotonics and peripheral vasoconstrictors is needed to effectively reduce blood loss.
