Insights
Perioperative ketorolac use in pediatric lower extremity osteotomies showed no increased risk of osseous or soft tissue complications. This study supports the safety of ketorolac for pain management in pediatric orthopaedic surgery.
Area of Science:
- Pediatric Orthopaedics
- Pain Management
- Surgical Complications
Background:
- Ketorolac is effective for pediatric surgical pain relief.
- Concerns exist regarding ketorolac's potential complications in pediatric orthopaedics, including nonunion, delayed union, and blood loss.
- This study addresses these concerns by examining complications associated with perioperative ketorolac use.
Purpose of the Study:
- To evaluate the safety and complication rates of perioperative ketorolac in children undergoing lower extremity osteotomies.
- To compare outcomes between children who received ketorolac and those who did not.
Main Methods:
- Retrospective review of 327 children undergoing osteotomy surgery with at least 6 months follow-up.
- Comparison of complication rates (osseous, soft tissue, union, wound healing) between 299 patients receiving ketorolac and 28 not receiving ketorolac.
- Analysis of estimated blood loss and transfusion requirements.
Main Results:
- No significant differences in osseous or soft tissue complications between ketorolac and non-ketorolac groups.
- Low rates of delayed union (0.7% overall) and wound complications (4.9% overall) with no significant group differences.
- No significant difference in estimated blood loss or need for blood transfusion between groups.
Conclusions:
- Perioperative ketorolac use in children undergoing lower extremity osteotomies is safe.
- The study supports the use of ketorolac for pain management in this pediatric surgical population.
- No increased risk of union or wound complications was observed.
Background:
Ketorolac has previously been shown to afford good pain relief in children undergoing surgery. Due to concerns about potential complications, particularly nonunion, delayed union, and excessive blood loss, ketorolac use has been limited in pediatric orthopaedics. The goal of this study is to examine complications associated with the perioperative use of ketorolac in children undergoing lower extremity osteotomies.
Methods:
A retrospective review was conducted of 327 consecutive children undergoing osteotomy surgery who had a minimum of 6 months follow-up. Of the 327 patients, 299 patients (625 osteotomies) had received ketorolac perioperatively and 28 (57 osteotomies) had not.
Results:
There was no significant difference in the rate of either osseous or soft tissue complications between the 2 groups. There were no nonunions in either of the groups. Delayed union occurred in 5 of 682 osteotomies (0.7%), including 0.6% in the ketorolac group (4/625 osteotomies), and 1.8% (1/57 osteotomies) in the nonketorolac group (P=0.893). Wound complications occurred in 16/327 patients overall (4.9%), including 13/299 (4.3%) in the ketorolac group and 3/28 (10.7%) in the nonketorolac group (P=0.301). There was no significant difference in estimated blood loss (EBL) (P=0.584) or the need for blood transfusion (P=0.777) between the 2 groups. Of the 19 occasions when blood was transfused perioperatively in the ketorolac group, 15 patients had undergone unilateral (3 patients) or bilateral (12 patients) varus derotational osteotomy as part of their surgery. Overall, 15 of 113 patients (13.3%) in the ketorolac group who underwent unilateral or bilateral varus derotational osteotomy required blood transfusion, with rates of 31.8% (7/22) in those who had undergone concomitant pelvic osteotomy(ies) and 8.7% (8/91) in those who had not.
Conclusions:
The results of this study support the safety of perioperative ketorolac use in children undergoing lower extremity osteotomies.
