Using a computer-generated random number table, patients were randomized to three groups: Control Group(n=30), ANH Group(n=30) and AHH Group(n=30). Patients underwent standard preoperative preparation for cytoreductive surgery according to institutional standards.All patients who underwent a standard anesthesia protocol and similar surgical procedures were considered for the analysis. For this purpose, investigators only included patients who underwent the following interventions: radical hysterectomy, bilateral adnexectomy, one or more bowel resection, peritonectomy, pelvic lymphadenectomy and extended periaortic lymphadenectomy. The patient would be ruled out of the experiment when the participant was accompanied with any kind of serious complications such as wakening delay and drug allergy.
