Objective: We sought to report the safety and effectiveness of bleeding control using a large amount of highly diluted vasopressin in laparoscopic management of interstitial pregnancy.
Study design: This was an uncontrolled retrospective review of 20 patients who were laparoscopically treated for interstitial pregnancy using a large amount of highly diluted vasopressin. For hemostasis, 1 ampule of vasopressin was diluted in 1000 mL of normal saline (1000-fold) and 150-250 mL of diluted vasopressin was injected in the uterus below interstitial pregnancy.
Results: Mean patient age and gestational age was 33.5 years and 6.7 weeks, respectively. Mean blood loss was 24 mL. The mean serum human chorionic gonadotropin level was 10,950, 4065, and 959 mIU/mL on the day of operation and postoperative days 1 and 4, respectively.
Conclusion: Laparoscopic management of interstitial pregnancy using a large amount of highly diluted vasopressin is safe and effective in hemostasis with minimal blood loss and no complications.
