Comparison of Concentration of Vasopressin During Robot-assisted Laparoscopic Myomectomy

Not Applicable
Completed
Conditions
Uterine Leiomyoma

Registration Number
NCT04874246
Lead Sponsor
Seoul National University Hospital
Brief Summary

The purpose of this study is to compare the effect of the concentration of vasopressin, which is used as a method for reducing blood loss in robot-assisted laparoscopic myomectomy.

Detailed Description

This study is to compare the effect of the concentration of vasopressin, which is used as a method for reducing blood loss in robot-assisted laparoscopic myomectomy. We would like to evaluate the feasibility and validity of this study for future Phase III randomized clinical trials through this preliminary randomized assignment study.

Uterine fibroids are the most common tumors in women, and uterine myomectomy, which is performed as a treatment for them, is basically a high risk of bleeding and blood transfusion. A common method to reduce intraoperative bleeding is to inject diluted vasopressin into the subserosal areas of the fibroids. However, no proper level of vasopressin dilution has been determined so far, so we want to determine an effective dilution concentration of vasopressin that can minimize side effects through this clinical trial.

Diluted Vasopressin Group 1VasopressinDuring robot-assisted laparoscopic myomectomy, diluted vasopressin (a solution prepared by mixing 20 units of vasopressin with 50 ml of normal saline to make a total of 100 ml) was injected before uterine serosal incision.
Diluted Vasopressin Group 2VasopressinDuring robot-assisted laparoscopic myomectomy, diluted vasopressin (a solution prepared by mixing 20 units of vasopressin with 200 ml of normal saline to make a total of 100 m) was injected before uterine serosal incision.
Diluted Vasopressin Group 3VasopressinDuring robot-assisted laparoscopic myomectomy, diluted vasopressin (a solution prepared by mixing 20 units of vasopressin with 400 ml of normal saline to make a total of 100 m) was injected before uterine serosal incision.
