It has been found that narcotic analgesics (morphine, fentanyl and dipidolor), inhalation anesthetics (phthorothan and frilen) and an intravenous anesthetic calypsol suppress lower esophageal contractility. Comparison of lower esophageal contractility with hemodynamic parameters and ACTH and cortisol blood plasma content have revealed a direct correlation. It is concluded that the method of dynamic control over lower esophageal contractility may be an objective test controlling the adequacy of anesthesia during various surgical interventions.
