Randomized Controlled Trial Comparative Study Clinical Trial[Differential administration of non-opioids in postoperative analgesia, I. Quantification of the analgesic effect of metamizole using patient-controlled analgesia].
The aim of this study was to investigate: 1. Whether the perioperative administration of metamizol causes a significant reduction in postoperative opioid requirements within the first 24 h after surgery. 2. The opioid-sparing effect after different types of operations. 3. Whether preoperative application of metamizol causes a significant reduction of the pain-score immediately after operation. ⋯ Perioperative administration of metamizol results in better pain relief and significantly lower buprenorphine requirements particularly after laparoscopic operations. To achieve a significant pain reduction immediately after the operation, the first dose should be applied before induction.
