Abstract:
Objective:To evaluate the analgesic efficacy of pericapsular nerve group (PENG) block in elderly patients undergoing hip replacement under subarachnoid block.Methods:Fifty patients of both sexes, aged 65-89 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with body mass index 20-30 kg/m 2, undergoing unilateral hip arthroplasty, were divided into 2 groups ( n=25 each) by a random number table method: PENG group and fascia iliaca compartment block (FICB) group.In PENG group, 0.4% ropivacaine hydrochloride 20 ml was injected around the nerve innervating the hip joint capsule under ultrasound guidance.In FICB group, 0.4% ropivacaine 30 ml was injected around the nerve innervating the fascia iliaca compartment under ultrasound guidance.Subarachnoid block was performed in both groups.Visual analog scale scores and scores for satisfaction with analgesia at rest and during activity were recorded before blockade (T 0), at 10, 20 and 30 min after blockade (T 1-3) and when placed in the position for spinal anesthesia (T 4). The cumulative consumption of sufentanil, effective pressing times of analgesic pump, and development of related complications were recorded at 6, 12, 24 and 48 h after operation (T 5-8). Results:Compared with FICB group, the VAS scores at rest and during activity were significantly decreased at T 1-4, and scores for satisfaction with analgesia during activity were increased in PENG group ( P<0.05). There was no significant difference between the two groups in the cumulative consumption of sufentanil and effective pressing times of analgesic pump ( P>0.05). One patient developed postoperative delirium in group FICB, and no patients developed puncture site infection and nerve damage after operation in two groups. Conclusion:PENG block produces better analgesic efficacy than FICB when used for elderly patients undergoing hip replacement under subarachnoid block.
