This systematic review and meta-analysis evaluated the analgesic efficacy of intrathecal morphine versus peripheral regional analgesia in 471 patients undergoing elective total hip arthroplasty. The study found no significant difference in pain scores at rest at 24 hours, but intrathecal morphine reduced cumulative intravenous morphine consumption by 11.38 mg (95% CI 4.31-18.45; P = 0.002) within the same timeframe.
Key findings
- No difference in pain score at rest at 24 hours between the two analgesic methods.
- Intrathecal morphine reduced cumulative intravenous morphine consumption by 11.38 mg at 24 hours.
- Intrathecal morphine showed superior pain relief at 8-12 hours for pain score at rest and on movement.
- Peripheral regional analgesia resulted in a lower rate of in-hospital pruritus.
Why it matters
Understanding the comparative efficacy of analgesic techniques is crucial for optimizing postoperative pain management in total hip arthroplasty, potentially influencing recovery and patient satisfaction.
What to keep in mind
The quality of evidence was moderate to low, indicating a need for further high-quality randomized controlled trials.
