Postoperative analgesic effectiveness of ultrasound-guided transmuscular quadratus lumborum block in congenital hip dislocation surgery : A randomized controlled study.

Abstract

BACKGROUND/OBJECTIVE:

Congenital hip dysplasia (CHD) defines a spectrum of pathologies in which the acetabulum and proximal femur of babies and children abnormally develop. Open surgery in congenital hip dysplasia leads to severe postoperative pain. The aim of this study was to evaluate the effectiveness of ultrasound-guided quadratus lumborum block (QLB) in pediatric patients undergoing surgery for congenital hip dysplasia.

MATERIAL AND METHODS:

Following ethical board approval, 40 children aged between 1-5 years undergoing surgery for congenital hip dysplasia were randomized into two groups. Patients (n = 20) received ultrasound guided quadratus lumborum block (group QLB) using 0.5 mL/kg body weight 0.25% bupivacaine preoperatively. The same standard postoperative analgesia protocol was used in both groups. Pain scores, parental satisfaction, requirement for ibuprofen and opioids were recorded. Pain was measured using the face, legs, activity, crying, consolability (FLACC) scale.

RESULTS:

The FLACC scores were lower at 30min and 1h, 2h, 4h, 6h, 12h and 24h in the QLB group when compared to the control group (p < 0.05). The requirement for rescue opioid analgesia was statistically significantly higher in the control group when compared to the QLB group (15/20 vs. 3/20, p < 0.001). Rate of ibuprofen usage in the ward was higher in the control group when compared to the QLB group (14/20 vs. 4/20, p = 0.004). Parental satisfaction was higher in the QLB group (p < 0.001).

CONCLUSION:

Ultrasound-guided quadratus lumborum block reduces pain scores and analgesic requirements following congenital hip dysplasia surgery.
