Intraoperative Carbetocin to Decrease Blood Loss During Hysteroscopic Myomectomy

Submucous myomas represent one of the main indications of operative hysteroscopy. Since 1976 when Neuwirth and Amin reported the first five cases of excision of submucous myomas , several techniques have been developed in order to render hysteroscopic myomectomy a safe and effective procedure . Hysteroscopic myomectomy is currently considered the "gold standard" minimally invasive approach for the treatment of symptomatic submucous myomas . Patients undergoing hysteroscopic myomectomy are liable to significant blood loss, and hemodynamic and hematological disturbances. Excessive bleeding during hysteroscopic myomectomy remains a major challenge for the endoscopic gynecological surgeons. Many interventions were introduced to reduce the risk of bleeding during myomectomy. These include the use of utero-tonics such as oxytocin, or the use of anti-fibrinolytics such as tranexamic acid . The potential advantage of oxytocin infusion during hysteroscopic myomectomy is that it can maintains uterine contractility throughout the procedure, and thus, reduce blood loss . Carbetocin (1-deamino-1-monocarba-(0-2-methyltyrosine)-oxytocin) is a long-acting synthetic agonist analogue of the human oxytocin. When injected to a woman, it induces uterine contractions . Although many interventions have been described to reduce the intraoperative blood loss during hysteroscopic myomectomy, there is a need for a well-designed randomized controlled trials to identify the most efficient interventions, with reasonable safety profiles, to help the perform a safe and curative surgery.
