An Enhanced Recovery After Surgery Protocol Decreases the Use of Narcotics in Infrainguinal Bypass Patients

"Enhanced recovery after surgery" (ERAS) protocols use a multisystem approach to target homeostatic physiology via opioid-minimizing analgesia. The aim of this study is to determine if an ERAS protocol for lower extremity bypass surgery improves pain control and decreases narcotics.

From July 2020 through June 2021, all patients that underwent infrainguinal lower extremity bypass procedures were subject to the ERAS protocol and compared to a "pre-ERAS" group between June 2016 through May 2020. Preoperatively, ERAS patients were given celecoxib, gabapentin, and acetaminophen while postoperatively they were given standing acetaminophen, gabapentin, ketorolac, and tramadol with as needed use of oxycodone. Pain scores were recorded using a numerical rating pain scale. Demographics, length of stay, 30-day complications, and disposition metrics were recorded.

There were 50 patients in the ERAS group, compared to 114 before its implementation. The mean age was 70.5 (ERAS group) versus 68.7 (pre-ERAS group) and a majority were male (P > .05). Enhanced recovery after surgery patients were less likely to have chronic kidney disease (P = .01). Enhanced recovery after surgery patients had improved length of stay (3.6 ± 2.3 days vs 4.8 ± 3.2 days, ERAS vs pre-ERAS, P = .01). There was no significant difference between groups for the remaining demographics (P > .05). One patient (2%) in the ERAS group used patient-controlled analgesia, compared to 30 patients (26%) in the pre-ERAS group (P < .001). Cumulative pain control in the first 12 hours was significantly better in the ERAS group (P = .05). Pain control at discharge was similar between the 2 groups (3 pain score vs 3 pain score, pre-ERAS vs ERAS, P > .05).

Our study utilized a multisystem approach to optimize the physiologic stress response to vascular surgery while reducing high potency narcotic use. We show that an ERAS protocol provides noninferior pain control with less potent pain medication and improves the length of stay for patients undergoing infrainguinal bypass surgery.
