摘要

The effectiveness of erector spinae plane block (ESPB) in preventingchronic pain after posterior lumbar surgery remains controversial. The primaryhypothesis of this study was that ESPB reduces the incidence of chronic pain for 3months after posterior lumbar surgery. In this prospective, randomized,parallel-group study, a total of 120 patients who underwent open posterior lumbardecompression surgery under general anesthesia were randomized into two groups. TheESPB group underwent preoperative bilateral ESPB, and the control group did notreceive the block. The primary outcome was the incidence of chronic pain at 3 monthsafter surgery. The secondary outcomes included postoperative morphine consumption,time to first ambulation after surgery, length of hospital stay and incidence ofchronic pain at 6 months after surgery. At 3 months, chronic pain was reported in21/56 (37.5%) and 28/58 (48.3%) patients in the ESPB and control groups,respectively (OR = 1.6; 95% CI, 0.7–3.3; p =0.245). The ESPB group had less postoperative morphine consumption (p < 0.001) and a shorter time to first ambulationafter surgery (p = 0.006) than the control groupdid. The length of hospital stay was similar. There was also no difference in theincidence of chronic pain at 6 months. ESPB did not reduce the incidence of chronicpain after posterior lumbar surgery, but it did facilitate early recovery aftersurgery.
