Abstract

Objective: Compare the postoperative analgesic efficacy in hip replacement surgery of continous ultrasound-guided quadratus lumborum block (QLB) versus fascia iliaca block  (FIB)  and the side effects of two methods. Subject and method: 60 patients with hip replacement surgery were divided into 2 groups: ultrasound-guided quadratus lumborum block (QLB) and fascia iliaca block  (FIB) to compare the analgesic efficacy and the side effects. Result: Mean VAS score at rest and movement of FIB group was lower than QLB group, but the difference was not statistically significant with p > 0.05 and both lower than 4. The rate of needing to use PCA-morphine to rescue between 2 groups was low and there was no difference. The satisfaction of the FIB group was higher than QL group (96.6% versus 80%), the difference was statistically significant with p < 0.05. Muscle weakness of group QL is lower than that of FIB group (3.3% versus 20%) and the difference is statistically significant with p < 0.05. The level of weakness of the 2 groups is baseline level I (Bromage). The rate of  side effects are low and there is no difference between the 2 groups. Conclusion: Both methods have good analgesic effects for patients after hip replacement surgery, the FIB group has a higher satisfaction, but more muscle weakness.
