It was reported in a journal article entitled : gas embolism during versapoint hysteroscopic myomectomy.This is a case report concerning a 40-year-old woman with menorrhagia secondary to uterine fibroids.During the procedure, the patient was placed in the lithotomy position with slight head-down tilt (5-10°), and the cervix was dilated with very little resistance to bonney parker size 8.A baggish 8-mm three-channel operating hysteroscope was inserted through the cervix into the uterine cavity.Saline was insufflated through a hys-surgimat hysteroflator set at 250 ml min-1 and initial pressure of 75 mmhg.To reduce fluid absorption the maximum insufflation pressure was adjusted according to the mean arterial pressure.Further, hysteroscopic versapoint spring (ethicon) endometrial ablation and submucous myomectomy were under general anaesthetic with saline as the distension medium.Intraoperatively an acute and profound drop in the patient's end-tidal carbon dioxide and oxygen saturation suggested of gas embolism, the procedure was then abandoned which the patient was treated with 100% oxygen.The patient was then transferred to the recovery ward for 90 min.She remained stable with an oxygen saturation of >97% on 5 l of oxygen via a facemask, with a normal heart rate and blood pressure.After several hours of observation on the gynaecology ward she was discharged later the same day.It was reported by the authors that there are three factors which may have contributed to the gas embolism: (a) head-down tilt with a patulous cervix; (b) versapoint vaporization, and (c) air within the fluid insufflation set.In conclusion, it is suggested that further evaluation of versapoint is required, and that this case highlights the need for vigilance when preparing for and performing hysteroscopic surgery.
