Abstract:

Objective To investigate the clinical effect of ultrasound ⁃guided“bow tie”fascia iliac plus sacral plexus block in hip arthroplasty. Methods A number of 66 patients aged 18⁃65 to undergo unilateral hip replacement were selected in our hospital from September 2019 to January 2020. They were randomly divided into 2 groups：ultrasound⁃guided iliac fascia plus sacral plexus block（group F，n = 33），ultrasound⁃guided lumbosacral plexus block（group C，n = 33）. The two groups were compared in terms of the ultrasound imaging and puncture injection time，the times of repeated punctures，heart rate（HR）and mean arterial pressure（MAP）at different time points，resting VAS score，Lovett muscle strength score，and nerve block ⁃ related complications at different time points after surgery. Results Compared with group C，group F had no significant differences in HR and MAP（P > 0.05）and in VAS scores 1，4，8，24 and 48 h after surgery（P > 0.05）. The time of ultrasound imaging and puncture injection in group F was significantly shorter than group C （P < 0.05）. The times of repeated puncture in group F were significantly less than group C（P < 0.05）. There was no significant difference in 24 and 48 h Lovett muscle strength score postoperatively（P > 0.05）. No nerve block⁃related complications were observed in both groups. Conclusion The ultrasound⁃guided“bow tie”fascia iliac plus sacral plexus block has a good analgesic effect in hip replacement surgery. The method is simple and effective，and it can be applied and promot-ed clinically.
