[Gas exchange and pulmonary hemodynamics in obese patients during epidural anesthesia and spontaneous respiration].

The function of external respiration, gas and ABB of blood, hemodynamics of the lesser circulation were studied during abdominal operations in patients with the IV degree obesity performed under conditions of epidural anesthesia with spontaneous respiration. On the basis of clinical and laboratory findings a conclusion was made on the adequacy of the method of epidural anesthesia with spontaneous respiration resulting in a considerably less amount of pulmonary complications.
