Résumé de l'étude

60 elderly patients undergoing hip fracture surgery were randomized to receive either suprainguinal fascia iliaca compartment block (FICB) alone (n=30) or FICB combined with pericapsular nerve group (PENG) block (n=30). The primary outcome of interest was the pain score at rest 12 hours after surgery, measured by the numerical rating scale (NRS). Secondary outcomes included pain scores at rest and with movement at various time points within 48 hours, time to first sit up without pain, rescue morphine requirements, opioid-related side effects, incidence of delirium, in-hospital morbidities and mortality, and length of hospital stay. Outcomes were assessed at 4, 8, 12, 24, 36, and 48 hours post-surgery. Overall, the results of the study revealed no significant difference in pain scores at rest or with movement between the two groups at any time point. The combined FICB and PENG block did not enhance postoperative analgesic or recovery outcomes compared to FICB alone. The findings suggest that adding a PENG block to FICB does not provide additional analgesic benefits.
