Background Enhanced recovery after surgery programs has incorporated gabapentin as part of a multimodal analgesia protocol. The preemptive use of gabapentin was found to be beneficial due to its opioid‐sparing effect. However, excessive sedation and delayed discharge from postanesthesia recovery units are of concern. The aim of this study was to investigate whether preoperative gabapentin increased the length of stay in the recovery unit. Methods This retrospective cross‐sectional study was carried out over a period of 2 months in the postanesthesia care unit ( PACU ) of a tertiary care hospital in Canada. Two hundred and twenty‐eight consecutive patients who underwent elective surgical procedures and who required a longer than 2‐hour stay in the PACU were included. Prolonged stays caused by respiratory inadequacy, hemodynamic instability, nausea, vomiting, pain, and loss of consciousness were recorded. The data were collected from patients’ charts and nursing flow sheets. Results All patients were grouped into those who received 300 mg gabapentin ( n = 108), 600 mg gabapentin ( n = 41), and no gabapentin ( n = 139). No significant difference was observed between the groups in terms of opioid consumption, respiratory inadequacy, nausea, vomiting, and hemodynamic parameters. Gabapentin administration groups had significantly lower postoperative pain scores ( P < 0.001). Decreased level of consciousness occurred significantly more often in a dose‐dependent fashion in the gabapentin groups and led to a longer stay in the PACU ( P < 0.001). Conclusion In the setting of enhanced recovery after surgery, gabapentin did reduce pain scores, but at the cost of delayed discharge from the recovery room. Future studies are needed to evaluate the efficacy of gabapentin in this setting.
