Hysteroscopic surgery requires anesthesia. If the hysteroscopic surgery operation time is short, such as doing endometrial polypectomy, endometrial pathology biopsy, etc., and the operation is completed within 30 minutes, intravenous anesthesia can be used. If the hysteroscopic surgery operation time is longer, such as uterine adhesions, moderate or severe uterine adhesions, type 1 type 2 submucosal fibroid removal, including uterine scar pregnancy or uterine diverticulum repair, or uterine diverticulum outflow tract incision, these surgeries have the possibility of choosing lumbar anesthesia, and usually do not need to be done with general anesthesia intubation. Hysteroscopic surgery requires anesthesia, depending on the operation, the difficulty of the operation, the length of the operation, the choice of anesthesia varies. If the hysteroscopic operation is completed within 30 minutes, intravenous general anesthesia is used. If the surgical hysteroscopy operation time is longer, such as moderate to severe uterine adhesions, intraoperative ultrasound machine monitoring needs to be used, or 1, 2 type of submucosal fibroids, large diameter or uterine scar pregnancy removal, the operation time is longer or the coefficient of difficulty is larger, will choose lumbar anesthesia surgery.
