Does PENG-LFCN Block Have Significant Optimization Effect?

Objective: To compare the clinical effects of pericapsular hip nerve block (PENG) combined with lateral femoral cutaneous nerve block (LFCN) and hourglass iliac fascial space block (FICB) in total hip replacement (THR) in elderly patients. Method: Sixty elderly ASAⅡorⅢ patients of both sexes, aged 65-85 yrs., with BMI 18-25 kg/m2, were divided into two groups by random number table method: FICB (group F, n=30) and PENG-LFCN (group PL, n=30). FICB with hourglass method was performed under ultrasound guidance in group F, and PENG-LFCN block was performed in group PL. After confirming the efficacy of nerve block,total intravenous anesthesia was carried out to maintain bispectrality index values 40-60.Postoperative sufentanil and tropisetron were used for PCIA. The consumption of propofol ,opioid analgesics during operation,postoperative recovery, and the incidence of quadricep muscle weakness at 1h after surgery,the incidence of adverse reactions and the satisfaction score of postoperative recovery and the occurrence of adverse reactions within 48h after surgery was recorded. Result: There were no significant differences in intraoperative medication, postoperative recovery and postoperative adverse reactions between the two groups, but the incidence of postoperative quadriceps muscle weakness in the group PL was less than that in the F group at the same time (P<0.05), and the postoperative recovery satisfaction score of the group PL was significantly higher than that of the group F. Conclusion: Fewer drugs resulted in higher postoperative recovery satisfaction. PENG-LFCN block is worth promoting.
