Comparison of analgesic effect of intraarticular buprenorphine, fentanyl and morphine following arthroscopic surgery of knee

Background and Aims : Pain after orthopaedic surgery depends on the site and extent of surgery and the preoperative use of analgesics by the patient. Arthroscopic procedures patients large incisions and decreased morbidity compared with open incisions but has not eliminated pain. At present several techniques are available to treat pain following either peripherally or centrally mediated analgesia), local anaesthetics, non corticosteroid s, clonidine and cryotherapy. administration of morphine, fentan prospective, randomised, placebo controlled, double blind comparative study conducted in 80 patients of either sex, who underwent arthroscopic surgery of status were included in the study. pts were randomly assigned equally to one of the 4 groups of 20 each by a sealed envelope method. The groups were Group A: Group B- Patients receiving IA Fentanyl 50mcg in 20 ml normal saline. 20 ml normal saline. Group D of analgesia along with hemodynamic parameters and side effects. data were analysed using student's t continuous variables and Chi - found that 100mc g buprenorphine or 0.5% bupivacaine when injected intra postoperative pain control and reduced supplementary analgesic requirement when compared to the groups. Intra-articular buprenorphine and fentanyl requirement in the first 8 hours following arthroscopic knee procedures. It also revealed that buprenorphine and fentanyl are better intra-articular analgesics than morphine. While during early post-operative period, it lacked analgesic efficacy in the
