Study Summary

35 patients presenting to the emergency department with suspected hip fracture were randomized to receive either standard systemic analgesia alone (SOC group) or systemic analgesia combined with an ultrasound-guided pericapsular nerve group (PENG) block. 32 patients were included in the final analysis, including 15 patients in the PENG group and 17 patients in the SOC group. The primary outcome was morphine consumption per hour from the time of randomization until 24 hours or until surgery, if performed earlier. Secondary outcomes included total morphine consumption, change in pain intensity measured by the numeric rating scale (NRS), maximum NRS pain score during emergency department stay, adverse events, and emergency department length of stay. Overall, the results demonstrated that patients receiving the PENG block required less opioid analgesia during emergency care compared with those receiving standard analgesia alone, while pain scores, adverse events, and length of stay were generally similar between groups.
