Carbon Monoxide poisoning and Air Embolism following Hysteroscopic Myomectomy: a case report.

INTRODUCTION

Uterine myomas are the most common benign uterine tumors. Hysteroscopic myomectomy has grown as a standard minimally invasive surgical procedure, but this technique is not free from complications.

CASE: An hysteroscopic myomectomy was performed on a 38 years-old woman. During the awakening after the procedure, she presented focal neurological deficits, thus arterial blood gas test and total body computerized tomography (CT) scan were urgently carried out. They revealed a very high carboxyhemoglobin level and abdominal venous air embolism. The patient stayed in Trendelenburg position and under mechanical ventilation with 100% oxygen concentration. Fortunately, a few hours later she was fully awake and was able to be successfully extubated, being discharged to the surgical ward three days later fully recovered.

CONCLUSION

Carbon monoxide poisoning during hysteroscopic resection is a rare but potentially fatal complication that anesthetists, gynecologists, and critical care physicians should be aware of.
