Abstract:
Objective To evaluate analgesic effect of bupivacaine infiltration in trocar incision after laparoscopic surgery.Methods 90 patients were randomly divided into 3 groups after laparoscopic cholecystectomy.In group 10.25% bupivacaine 20 ml(50 mg) injection, in group 2 sterile NS 20 ml infiltrated in the muscular fasciae of the trocars, in group 3 patient-controlled intravenous analgesia(PCIA) was used.In 2, 6, 12 and 24 hours after the intervention, the pain intensity was recorded with the use of a Visual Analogue Scale ( VAS), time of flatus passing was recorded as well.Results Patients with bupivacaine or PCIA had statistically significant in pain score compared with patients with NS especially within 12 hours after the surgery (t2h = 8.475; t6h = 5.356; t12h = 3.496, P ＜ 0.05) while the difference was not statistically significant between the 3 groups at 24 hours.The time of passing flatus in group 1 patients with bupivacaine was earlier than with PCIA ( x224h = 5.406, P ＜ 0.05 ) .Conclusions Bupivacaine infiltrated in trocar incision after laparoscopic surgery reduced postoperative pain, and did not disturb peristalsis reflex recovery of the intestines.
