Insights
Psoas compartment block (PCB) provides superior postoperative pain relief compared to caudal block in children undergoing hip surgery. This study found PCB led to longer analgesia and less morphine use in pediatric patients.
Area of Science:
- Pediatric Anesthesiology
- Regional Anesthesia
- Pain Management
Background:
- Lower-limb peripheral nerve blocks are increasingly popular in pediatric anesthesia.
- Open hip reduction and osteotomies are common orthopedic procedures in children requiring effective postoperative pain management.
Purpose of the Study:
- To compare the analgesic efficacy of psoas compartment block (PCB) versus caudal block in pediatric patients undergoing open hip surgery.
- To evaluate postoperative pain scores, analgesic consumption, and complications associated with each block technique.
Main Methods:
- Forty pediatric patients (1-6 years) were randomized to receive either a caudal block (n=20) or a PCB (n=20).
- Both blocks utilized ropivacaine 0.25% with epinephrine.
- Primary outcome was 24-hour morphine consumption; secondary outcomes included pain scores and complications.
Main Results:
- Patients receiving PCB had significantly lower cumulative morphine consumption and a longer time to first rescue analgesia compared to the caudal block group.
- No significant differences in intraoperative complications were observed.
- Higher incidence of urine retention was noted in the caudal block group.
Conclusions:
- Single-shot PCB offers superior postoperative analgesia compared to single-shot caudal block in small children undergoing open hip reduction/osteotomies.
- PCB is a more effective regional anesthetic technique for this patient population, reducing opioid requirements.
Background:
Lower-limb peripheral nerve blocks in pediatrics have gained much more popularity in the last few decades. Our purpose of this study was to compare the postoperative analgesic effects between psoas compartment block (PCB) and caudal block in small children undergoing open hip reduction/osteotomies.
Methods:
Forty American Society of Anesthesiologists physical status I-II children aged 1 to 6 years planned to undergo open hip reduction/osteotomies were administered general anesthesia and then randomly assigned to receive 1 of 2 regional anesthetics: caudal block (group C, n=20) or PCB (group P, n=20). Ropivacaine 0.25% with epinephrine (5 μg/mL) was used in both blocks. The primary outcome of the study was the total consumption of morphine in the first 24 postoperative hrs. Secondary outcomes included dose of intraoperative fentanyl, occurrence of intraoperative hypotension or bradycardia, postoperative pain scores, time to first morphine analgesia, and occurrence of postoperative vomiting or urine retention.
Results:
The cumulative dose of morphine administered in the ward in the first postoperative 24 hrs and the time to first rescue morphine dose were higher in group C than in group P (P<0.001). There were no differences between the 2 groups regarding intraoperative and postoperative complications except for the incidence of urine retention, which was higher in group C than in group P (P=0.037).
Conclusions:
Use of single-shot PCB is superior to single-shot caudal block regarding length of postoperative analgesia and cumulative dose of morphine in small children undergoing open hip reduction/osteotomies.
