RESUMEN
A total of 230 children undergoing closed reduction and percutaneous pinning of supracondylar humerus fractures were analyzed retrospectively. Severe pain (score ≥ 7/10) was reported in 10% of general anesthesia-only patients in the postanesthesia care unit and in 28% of the 130 admitted patients. The 36 patients who received ultrasound-guided regional analgesia+general anesthesia had decreased intraoperative opioid consumption and postanesthesia care unit pain scores. After admission, pain scores and opioid consumption did not differ between fracture and anesthesia types. No patient developed compartment syndrome. Severe pain is frequent after closed reduction and percutaneous pinning of supracondylar humerus fractures. Further study of ultrasound-guided regional analgesia is needed.
