Objectives: One of the most prevalent benign tumors in women is uterine leiomyoma. Large quantities of fluid absorbed during myomectomy may cause serious problems such as volume overload and hyponatremia. The aim was to see how intraoperative oxytocin infusion affected irrigation fluid absorption in individuals having hysteroscopic myomectomy.
Materials and Methods: 50 women between 25-45 years who underwent hysteroscopic myomectomy and had an American Society of Anesthesiologists class I or II were evaluated in this randomized, double-blind clinical trial study. A 250 mL ringer solution containing 15 units of oxytocin was administered at a 125 mL/h in the oxytocin group (group S). In contrast, the placebo group (group P) received 1.5 mL of normal saline in the same amount of Ringer solution. Intraoperative hemodynamic alterations, fluid deficit, decreased hemoglobin, hematocrit, sodium, and albumin levels from baseline, complications, and the incidence of toxicity with the administered solutions were assessed intraoperative and 24 hours later.
Results: Group S had considerably reduced irrigation fluid volume (P = 0.021) and volume deficit (P = 0.001). The frequency of hypotension in individuals receiving oxytocin did not differ significantly from the placebo group (P = 0.26). In group S, serum hematocrit (P = 0.036) and sodium (P = 0.026) were decreased significantly.
Conclusions: Intraoperative oxytocin infusion during hysteroscopic myomectomy may be associated with reduced irrigation fluid absorption and the problems that come with it. As a result, this approach might decrease the risks associated with high amounts of irrigation fluid being absorbed during hysteroscopic myomectomy.
