• Fifty patients undergoing cholecystectomy either electively or urgently were treated in the postoperative period with the intrapleural injection of 30 mL of 0.75% bupivacaine hydrochloride with epinephrine (1:200 000). The frequency of narcotic administration and the postoperative stay were compared with those of 50 historical controls. The group receiving intrapleural regional analgesia had significant, prolonged pain relief requiring minimal narcotic analgesics in the first 24 hours postoperatively and had a significantly shortened hospital stay. There were no complications related to catheter insertion or bupivacaine toxic effects. This technique is safe and effective in controlling perioperative pain.
