ABSTRACT

Objective: To compare the efficacy of 7.5% ropivacaine against that of 0.9% saline solution for postoperative pain of elective laparoscopic cholecystectomy.
Setting: Christus Muguerza Hospital, Saltillo, Coah, Mexico.
Design: Double blind clinical assay.
Statistical analysis: Results were analyzed with the SPSS 11 software for Mac, using simple frequencies, central tendency measures and Mann-Whitney U test.
Patients and methods: Forty patients programmed for elective laparoscopic cholecystectomy, with clinical diagnosis of cholelithiasis confirmed through echography. Patients received randomly either ropivacaine or sodium chloride (contained in sterile 20 ml syringes, prefilled and coded by SAFE, in identical presentation). Postoperative pain was measured at 6, 12, 18, and 24 h, by means of the analogic visual scale.
Results: No differences existed regarding either gender, age, and postoperative pain at 6, 12, 18 y 24 h or use of rescue analgesics.
Conclusions: We were unable to demonstrate in this study the efficacy of ropivacaine to control postoperative pain as published by other authors; probably because of the use of higher analgesic doses, which, by itself, could suffice to control pain in both groups.
