Poor postoperative pain control impairs patient recovery and lengthens the duration of hospitalization after various surgeries. Local infiltration analgesia(LIA) has become an effective method for managing postoperative pain. This study aimed to investigate the efficacy of LIA with ropivacaine for postoperative pain control after cervical laminoplasty. In total, 68 patients undergoing cervical laminoplasty were included for retrospective review and divided into ropivacaine and control groups. The visual analogue scale (VAS) score, postoperative analgesic consumption, operative duration, intraoperative blood loss volume, incision length, hospitalization duration and incidence of complications were analyzed. In the ropivacaine group, the VAS score was 3.2 ± 1.4 at 4 hours postoperatively, which was lower than that of the control group(4.0 ± 1.4, P = 0.024). At 8, 12 and 24 hours after surgery, a significant difference was detected in the VAS score between the two groups(P †0.015). Sufentanil consumption was less in the ropivacaine group than in the control group in the first 4 hours postoperatively (25.6 ± 6.3 ”g vs 32.2 ± 6.8 ”g, P < 0.001), and similar results were observed in the first 8, 12, 24, 48 and 72 hours postoperatively(P < 0.001). Fewer patients required rescue analgesia in the ropivacaine group(8/33 vs 18/35 at 4-8 hours, P = 0.021; 9/33 vs 21/35 at 8-12 hours, P = 0.007). The hospitalization duration and time to ambulation were shorter in the ropivacaine group(8.5 ± 1.4 vs 9.6 ± 1.6 for postoperative duration, P = 0.002; 2.9 ± 0.7 vs 3.5 ± 0.8 for time to ambulation, P = 0.001). The incidence of nausea and vomiting was lower in the ropivacaine group than in the control group(30.3% vs 54.3%, P = 0.046). In conclusion, LIA with ropivacaine could effectively reduce postoperative pain, and postoperative analgesic consumption, and promote recovery after cervical laminoplasty. Cervical laminoplasty has been used widely and achieved satisfactory outcomes in treating multilevel cervical lesions, including cervical spondylotic myelopathy(CSM), congenital cervical stenosis(CCS), and ossification of the posterior longitudinal ligament(OPLL) 1-3. However, surgical treatment often results in serious pain, which can impair patient recovery and lengthen the hospitalization duration. Recently, local infiltration analgesia (LIA) has emerged as a good choice for postoperative analgesia due to its simplicity and low-cost 4,5. LIA has been used in various surgeries with favorable outcomes and without major side effects 6. The benefits of LIA in spinal surgery are also well known; however, its use has been limited to lumbar decompression and discectomy, and spinal fusion surgery 7,8. Few studies have focused on the effect of LIA on postoperative pain control in cervical laminoplasty. Therefore, we conducted this clinical study to retrospectively evaluate the efficacy of LIA with ropivacaine for managing postoperative pain after cervical laminoplasty.
