Interpleural Analgesia with Morphine and Bupivacaine in Pneumothorax

Introduction:interpleural block offers postoperative analgesia with significant results in surgical interventions. Objective:to evaluate the benefits of interpleural block with 0.5 % Bupivacaine and Morphine by means of interpleural catheter in patients operated on pneumothorax pain relief. Method:an observational, analytical study of cases and controls was carried out in patients undergoing emergency surgery for pneumothorax at Abel Santamaria Cuadrado general teaching hospital, from January to October 2018. The patients were randomized 1:1 (20 cases / 20 controls). Results:a predominance of patients over 65 years of age was found. Pulmonary emphysema predominated (40 % in the case group / 50 % in the controls). ASA II patients predominated. No significant variations were found in the hemodynamic parameters or their association with the type of analgesia (p> 0,05). It was found that the quality of analgesia evaluated and the type of analgesia applied showed a significant relationship (p = 0,0001). In the case group, nausea (0,5 %) and hypotension (0,5 %) predominated; and in controls the tachycardia (75 %). Conclusions:the administration of Bupivacaine and Morphine using interpleural catheter in patients operated on pneumothorax presented good results with few complications, stable hemodynamic parameters and satisfactory postoperative analgesia.
