Oxytocin infusion significantly reduced operative blood loss and transfusion rates during laparoscopic-assisted vaginal hysterectomy (LAVH) for large uteri. This safe and inexpensive method is beneficial for patients undergoing LAVH.

Area of Science:

  • Gynecologic Surgery
  • Obstetrics and Gynecology
  • Pharmacology in Surgery

Background:

  • Laparoscopic-assisted vaginal hysterectomy (LAVH) for large uteri presents challenges with operative blood loss.
  • Effective methods to mitigate blood loss during LAVH are crucial for patient safety and outcomes.

Purpose of the Study:

  • To evaluate the efficacy of intraoperative oxytocin infusion in reducing blood loss during LAVH for large uteri (≥500 g).
  • To assess the safety and cost-effectiveness of oxytocin as an adjunct in LAVH.

Main Methods:

  • A prospective clinical study involving 88 women undergoing LAVH for large benign uterine tumors.
  • Participants were divided into two groups: one receiving oxytocin infusion (40 mU/min) and a control group.
  • Operative blood loss, transfusion rates, and postoperative outcomes were compared between groups.

Main Results:

  • The oxytocin group (Group A) experienced significantly less blood loss (364.1 ± 173.2 mL) compared to the non-oxytocin group (Group B) (485.7 ± 321.6 mL; p < .05).
  • Blood transfusion rates were markedly lower in the oxytocin group (6.1%) versus the non-oxytocin group (26.7%; p < .05).
  • No significant differences were observed in patient demographics, uterine weight, postoperative stay, or complications between the groups.

Conclusions:

  • Intraoperative oxytocin infusion effectively decreases operative blood loss and transfusion requirements in LAVH for large uteri.
  • Oxytocin promotes uterine contractions, reducing uterine perfusion and associated bleeding.
  • Oxytocin represents a safe, inexpensive, and valuable method for managing blood loss during LAVH.
