Comparison of Cumulative Opioid Consumption Between Variable-Rate Feedback Infusion and Fixed-Rate Basal Infusion Modes of Intravenous PCA Following Mixed Surgery
Recruiting now · Not applicable
Conditions studied: Surgery, Pain Management, Opioid Consumption, Patient-controlled Analgesia
In brief
Perioperative pain management affects patient recovery. However, the rate of moderate to severe postoperative pain is as high as 73.8%, which hinders recovery and increases the risk of complications. Although opioids are the first-line analgesics, excessive use leads to adverse reactions. The traditional fixed-rate PCA mode is difficult to match the changes in postoperative pain. This study will compare different PCA mode optimization strategies, assuming that they can reduce opioid dosage, improve analgesic effect, and reduce adverse reactions, providing high-quality evidence-based basis for postoperative analgesia and promoting individualized and intelligent management.
