Abstract :

 Background: The aim of this prospective, randomized, single blind study was to evaluate the efficacy of continuous thoracic paraverteal block for post–operative pain relief in patients undergoing open cholecystectomy.Methods: Sixty adult patients undergoing open cholecystectomy under general anaesthesia were randomized into two groups; Group C patients received systemic analgesics alone; Group P patients received intra–operative and post–operative paraverteal infusion of a solution containing 0.1% bupivacaine with 1 μg ml–1 fentanyl at 7 ml hr–1 in addition to systemic analgesics. Primary outcome measures were postoperative pain during rest (static pain) and coughing (dynamic pain); secondary outcome measures were post–operative patient controlled fentanyl consumption, post–operative nausea and vomiting , requirement of rescue antiemetic, hypotension, sedation, pruritus, motor block and respiratory depression; these were assessed at 6 hourly intervals for a period of 48 hrs in the post–operative period. Results were analyzed by the student’s T–test, Chi square test, Mann Whitney test and fisher’s exact test. P value <0.05 was considered significant. Results: The two groups were similar with regard to demographic factors (P>0.05). Paraverteal analgesia group caused a significant reduction in VAS scores during rest and coughing (static and dynamic pain) and post–operative patient controlled fentanyl consumption as compared to the control group (P<0.05. The incidence of side effects were similar in the two groups (P>0.05).Conclusions: Continuous thoracic paraverteal block reduces the post–operative static and dynamic pain along with post–operative patient controlled fentanyl consumption in patients undergoing open cholecystectomy
