Objctive: The present study, investigates the analgesic effects and complications of intra-articular neostigmine, tramadol, tenoxicam and bupivacaine on postoperative pain in patients undergoing day case knee arthroscopy. Subjects: Group 1 received 0.5 mg neostigmine, Group 2 received 100 mg tramadol, Group 3 received 20 mg tenoxicam, Group 4 received 20 ml 0.5% bupivacaine (control) in 20 ml normal saline intra-articularly at the end of the surgery. All patients had the same anaesthetic technique. Patients were observed in the recovery room with respect to pain scores, haemodynamic changes and postoperative analgesia at 1, 2 and 4 h postoperatively. Analgesic therapy in the recovery room was managed with 25 mg bolus doses of meperidine when the patients had visual analosue scale (VAS) scores higher than three points. The patients were discharged from hospital with a prescription for diclofenac 75 mg to be used as required. They were asked to complete their pain measures at 24 h and record their analgesic consumption. Results: There were no significant differences among the study groups regarding pain scores, haemodynamic changes, the first analgesic requirement time and complications. All patients in our study had adequate postoperative analgesia without any severe complication. Conclusion: Intra-articular administration of neostigmine, tramadol, tenoxicam or bupivacaine is a simple and effective postoperative analgesic technique after outpatient arthroscopic knee procedures. |
