Improving recovery after microvascular decompression surgery for hemifacial spasm: experience from 530 cases with enhanced recovery after surgery (ERAS) protocol

Abstract

Objective

To assess the efficacy of microvascular decompression (MVD) for hemifacial spasm with an enhanced recovery after surgery (ERAS) protocol.

Methods

984 hemifacial spasm patients who underwent MVD from Jan 2017 to Dec 2017 were analyzed. They were divided into the conventional treatment group (control; n = 453) and the later ERAS group (n = 531). The multimodal ERAS protocol consists of 23 perioperative elements. Time to feeding, mobilization, and urinary catheter removal, wound pain, postoperative nausea and vomiting (PONV), and total, preoperative, and perioperative hospital length of stay (LOS), along with outcomes and complications, were analyzed.

Results

The patients in both groups had similar clinical characteristics. Patients in the ERAS group had significantly higher rates of early feeding (469 [88.5%], ERAS, vs. 183 [40.6%], control; p < 0.05), early mobilization (497 [93.7%], ERAS, vs. 215 [47.7%], control; p < 0.05), and early removal of urinary catheter (458 [86.4%], ERAS, vs. 175 [38.8%], control; p < 0.05). The ERAS group also had a significantly lower incidence of wound pain (135 [25.5%], ERAS, vs. 348 [77.2%], control) and PONV (173 [32.6%], ERAS, vs. 251 (55.7%), control) (p < 0.05) and significantly shorter preoperative (0.9 ± 0.3 d, ERAS, vs. 2.3 ± 0.6 d, control), postoperative (4.1 ± 0.4 d, ERAS, vs. 5.8 ± 0.7 d, control), and total LOS (5.2 ± 0.3 d, ERAS, vs. 8.8 ± 0.6 d, control) (p < 0.05). There was no significant difference in outcomes or surgical complication rates between two groups.

Conclusions

Implementation of the ERAS protocol for patients undergoing MVD procedures for the treatment of HFS improved the quality of perioperative care without an increase in adverse events.
