CANDEMIL, Renan Cardoso et al. Infiltrative analgesy in videocolecistectomy: a randomized clinical trial. ABCD, arq. bras. cir. dig. [online]. 2011, vol.24, n.4, pp.262-266. ISSN 0102-6720. http://dx.doi.org/10.1590/S0102-67202011000400003.
BACKGROUND: Large proportion of surgical patients experience severe pain postoperatively. AIM: To evaluate the analgesic efficacy of infiltration on incision of laparoscopic cholecistectomy with ropivacaine and the effect on opioids consumption. METHODS: A prospective, randomized, double-blind study was conducted, where 70 patients undergoing laparoscopic cholecistectomy were divided into two groups, I (infiltration) and C (control). After 12 hours of post-operative patients were interviewed and answered the Visual Analogue Scale. The consumption of opioids was evaluated through medical records at the time of interview. RESULTS: When comparing the intensity of pain in both groups, was noticed a better profile of pain in the intervention group, with 44.4% reported mild pain, moderate pain 50% and 5.6% severe pain. In group C the respective values were 38.2%, 50% and 11.8% (P = 0.622). The group I had lower average pain, 2.75, compared with group C, 3.75, but this result was not statistically significant (P = 0.319). Similarly group I opioids had a lower consumption than group C, 47.2% and 52.9% respectively, although with no statistical significance (P = 0.632). CONCLUSION: The infiltration of the incisions with ropivacaine, although without statistical significance, produced reduction in the postoperative pain, as well as reduced the consumption of opioids after 12 hours.
