Objective: To prospectively evaluate the efficacy of neurosurgical enhanced recovery after surgery (ERAS) protocol on the management of postoperative pain after elective craniotomies. Methods: This randomised controlled trial was conducted in the neurosurgical center of Tangdu Hospital (Fourth Military Medical University, Xi'an, China). A total of 129 patients undergoing craniotomies between October 2016 and July 2017 were enrolled in a randomized clinical trial comparing ERAS protocol and conventional care. The primary outcome was the postoperative pain score assessed by a verbal numerical rating scale (NRS). Results: Patients in the ERAS group had a significant reduction in postoperative pain score on POD 1 compared to patients in the control group (mean NRS 3.12 vs. 4.44, OR 0.0968, 95% CI 0.3299 to 2.317, p = 0.010). More patients (n = 44, 68.8%) in the ERAS group experienced mild pain (NRS: 1 to 3) on POD1 compared with patients (n = 23, 35.4%) in the control group (p < 0.05). A significant reduction in pain score was observed on POD 2 and POD 3 in the ERAS group compared with that in the control group (POD2: mean NRS 2.85 vs. 4.32, OR 0.2628, 95% CI 0.5619 to 2.379, p=0.002. POD3: mean NRS 2.32 vs. 4.03, OR 0.1468, 95% CI 0.9537 to 2.458, p < 0.001, respectively). In addition, the median postoperative length of hospital stay was significantly decreased with the incorporation of ERAS protocol compared to the controls (ERAS: 4 days, control: 7 days, P<0.001). Conclusion: Implementation of the neurosurgical ERAS protocol for elective craniotomy patients have significant benefits in alleviating postoperative pain and enhancing recovery after surgery compared to the conventional care. Further evaluation of this protocol in larger, multi-center studies is warranted.
