[Preanesthetic preparation and induction anesthesia in acute cholecystitis in middle-aged and elderly patients].

Under examination there were 59 elderly and senile patients with acute cholecystitis subjected to emergency operations. It was found that among 3 kinds of initial narcosis smooth course was notable in the phentanyl-sombrevin initial narcosis. The administration of thalamonal-sombrevin initial narcosis results in a certain inhibition of blood circulation, and gives adequate anesthesia during endotracheal intubation. The initial sombrevin narcosis is followed by inhibition of blood circulation and fails to give sufficiently deep anesthesia during intubation of the trachea.
