Effect of Bupivacaine Injection to the Trocar Site in Laparoscopic Cholecystectomy

42045

Aim: Laparoscopic cholecystectomy is less impact on postoperative pain as a minimally invasive procedure compared to open surgery. We aimed to show whether there are diffferences between the level of postoperative pain due to it was or not given local anesthetics on the trocar area in the laparoscopic cholecystectomy. Materials and Methods: 71 patients between ages 18-88 who had laparoscopic cholecystectomy were enrolled in our study. All patients were informed one day before the study about Visuel Analog Scala (VAS) and scoring system of pain severity from 0 to 10. The group 1 (n=34) was given 3 mL (15 mg) bupivacaine injection at the point of three trocar sites (except the first trocar site). The group 2 (n = 37) was defined as the control group. VAS levels of patients were recorded at postoperative 2., 4., 6., and 12. hours. We recorded the time until first need for analgesia and the total amount of analgesia at postoperative 12. hour. Results: In our study, lower postoperative VAS scores for the group 1 were recorded when compared with the second group. Statistically significant decrease was observed in postoperative VAS scores of group 1 at 2. , 4. , 6. hours. Bupivacaine was found effective at postoperative 12. hour (p 0.05). Analgesia needs were similar for both of two group (p 0.05). Conclusion: We think that VAS scores are lower three point of given bupivacaine in the grup 1.
