Four patients were studied for intercostals nerve blockade in cholecystectomy. All of the patients were poor risks (Class 4) and received premedication before the procedure. Intercostals nerve blockade (ICNB) of the 7th and 10th thoracic nerves on the right side was performed with lidocaine 1% plus adrenaline 5 ml. at each segment, T7-T10 (a total dose of 20 ml). Ventilation was controlled using intermittent positive pressure throughout the observation period. Heart rate and arterial pressure remained within normal limits in all patients.
