[Effects of surgical intervention on plasma levels of antidiuretic hormone and alpha-human atrial natriuretic polypeptide under sevoflurane anesthesia].
Effects of surgical intervention on plasma levels of antidiuretic hormone (ADH) and alpha-human atrial natriuretic polypeptide (alpha-hANP) under sevoflurane-nitrous oxide-oxygen anesthesia were evaluated in 24 patients, ranged in ages from 15 to 65, who underwent non-abdominal surgery (orthopedic surgery) or abdominal surgery (gastrointestinal or gynecological surgery). Anesthesia was induced and maintained with sevoflurane, nitrous oxide and oxygen. Succinylcholine was administered to facilitate tracheal intubation and pancuronium was given during abdominal surgery when needed. Lactated Ringer's solution was administered intravenously throughout the procedures. Neither plasma ADH nor alpha-hANP levels changed significantly during sevoflurane anesthesia alone for 20 min. Plasma ADH levels were unchanged during surgery in patients who underwent non-abdominal surgery, but they tended to increase although insignificantly after the recovery from anesthesia. On the contrary, plasma ADH levels increased significantly during surgery and in the recovery room in patients who underwent abdominal surgery. Plasma alpha-hANP levels were unchanged during surgery and in the recovery room in patients who underwent non-abdominal or abdominal surgery. The authors' findings suggest that ADH secretion was significantly stimulated with abdominal intervention but not with orthopedic one, furthermore neither anesthesia nor surgical stress induced any influence on plasma alpha-hANP levels.
