title: [Role of regional anesthesia in prevention of postoperative respiratory dysfunction].
abstract: The aim of the study is to evaluate postoperative respiratory dysfunction in abdominal surgery based on level of invention and type anesthesia and postoperative pain management.
  
  
  METHODS
  260 patients who underwent major abdominal surgery were assessed. 70 had operation in upper abdomen and were administered general anesthesia, 70 patients had same operation but had combined anesthesia inhalational and prolonged epidural on thoracic level. 120 patients were performed abdominal operation in lower abdomen 40 of them were administered with general anesthesia 40 patient had combined anesthesia inhalational with prolonged epidural and 40 had combined anesthesia inhalational and spinal anesthesia. We analyzed anesthesia and recovery period, postoperative pain management and sedation, the result of spirometria and arterial blood gasses.
  
  
  RESULTS
  both methods of regional anesthesia allowed to reduce amount of anesthetic agents and due to this shortened the time of anesthetic recovery. The results of spirometria were affected in all groups particularly in a group with abdominal surgery on upper region. Epidural anesthesia provided best result in postoperative pain management and improved result of spirometria in patients after abdominal surgery in upper and lower region. In addition patients after upper and lower abdominal surgery how received epidural analgesia in postoperative period had demonstrate better arterial blood gasses results than patients of all other groups. Method of spinal anesthesia did not demonstrate beneficial effects on the results of spirometria or arterial blood gasses. The rate of postoperative pneumonia was lower in groups with regional anesthesia.
  
  
  CONCLUSIONS
  extended-release epidural anesthesia was beneficial effects on postoperative respiratory dysfunction and reduces rate of pneumonia postoperatively.
