Epidural anesthesia for ovarian cancer surgery why double puncture points

Ovarian cancer exploratory surgery for comprehensive staging: standard ovarian cancer staging surgery includes: 1) abdominal longitudinal incision (from the pubic symphysis to 4 transverse fingers above the umbilicus) to ensure adequate exposure; 2) abdominal cytology (ascites, or pelvic cavity) , colonic sulcus, flushing fluid of the upper abdomen) comprehensive exploration of the pelvic and abdominal cavity; 3) careful exploration and biopsy (adhesion, ligation and suspicious parts, especially the colonic sulcus, diaphragm and mesentery, etc.); 4) omentectomy; 6) Total hysterectomy and double adnexectomy (high ligation of ovarian artery and vein); 7) pelvic and para-aortic lymph node removal (inferior mesenteric artery level).

It can be seen that the scope of the operation is wide, and the total hysterectomy is required, and the requirements for abdominal muscle relaxation are relatively high. A simple anesthesia cannot meet this requirement. Double point puncture can expand the scope of nerve tissue.

But unlike the general anesthesia mentioned above, it must be better, and spinal anesthesia is more suitable for postoperative analgesia. For this kind of lower abdominal surgery, the postoperative analgesia is better with intraspinal analgesia. Of course, the operation time is longer. In order to reduce the discomfort of the patient, general anesthesia combined with intraspinal anesthesia can be selected, and intraspinal analgesia is used after the operation. Pain is better.
