Postoperative analgesia for pediatric craniotomy patients: a randomized controlled trial

Area of Science:

• Anesthesiology
• Pediatric Neurosurgery
• Pain Management

Background:

• Craniotomy in pediatric patients frequently results in postoperative pain.
• Effective pain management is crucial to prevent complications, but optimal strategies remain unclear.
• This study investigated optimal postoperative analgesia in pediatric neurosurgery.

Purpose of the Study:

• To compare the efficacy and safety of different patient-controlled analgesia (PCA) regimens for postoperative pain management in pediatric neurosurgery.
• To identify the most effective analgesic formula for pediatric patients undergoing craniotomy.

Main Methods:

• A randomized controlled trial involving 320 pediatric patients (1-12 years) undergoing craniotomy.
• Four PCA groups were compared: control (saline), fentanyl, morphine, and tramadol.
• Pain scores and analgesic-related complications were recorded and analyzed.

Main Results:

• Morphine group demonstrated significantly lower pain scores at 1 and 8 hours post-surgery compared to all other groups.
• Tramadol and fentanyl groups showed reduced pain scores versus the control group.
• Nausea and vomiting were more prevalent in the tramadol group; the control group required more rescue analgesics. No respiratory depression or consciousness changes were observed.

Conclusions:

• Patient-controlled intravenous analgesia (PCIA) with morphine is the safest and most effective option for postoperative pain management in pediatric neurosurgery.
• Morphine PCIA offers superior pain control compared to fentanyl, tramadol, or saline.
• The study identified younger age, occipital craniotomy, and morphine treatment as factors influencing pain levels.
