Is multimodal analgesia associated with reduced narcotic use and improved pain control compared with traditional narcotic-based analgesics at discharge and in the immediate postoperative period after free flap reconstructive surgery?
In this cohort study of 28 patients receiving multimodal analgesia and 37 controls receiving traditional narcotic-based analgesics, multimodal analgesia was associated with lower morphine-equivalent doses administered postoperatively, better perioperative Defense and Veterans Pain Rating Scale pain scores, and lower morphine-equivalent doses prescribed at discharge compared with traditional narcotic-based analgesic controls.
The findings suggest that use of a perioperative multimodal analgesia regimen in patients undergoing free flap reconstruction in the head and neck is associated with decreased opioid requirement at discharge and in the immediate postoperative period and better pain control compared with traditional analgesic regimens.
An increase in narcotic prescription patterns has contributed to the current opioid epidemic in the United States. Opioid-sparing perioperative analgesia represents a means of mitigating the risk of opioid dependence while providing superior perioperative analgesia.
To assess whether multimodal analgesia (MMA) is associated with reduced narcotic use and improved pain control compared with traditional narcotic-based analgesics at discharge and in the immediate postoperative period after free flap reconstructive surgery.
Design, Setting, and Participants
This retrospective cohort study assessed a consecutive sample of 65 patients (28 MMA, 37 controls) undergoing free flap reconstruction of a through-and-through mucosal defect within the head and neck region at a tertiary academic referral center from June 1, 2017, to November 30, 2018. Patients and physicians were not blinded to the patients’ analgesic regimen. Patients’ clinical courses were followed up for 30 days postoperatively.
Patients were administered a preoperative, intraoperative, and postoperative analgesia regimen consisting of scheduled and as-needed neuromodulating and anti-inflammatory medications, with narcotic medications reserved for refractory cases. Control patients were administered traditional narcotic-based analgesics as needed.
Main Outcomes and Measures
Narcotic doses administered during the perioperative period and at discharge were converted to morphine-equivalent doses (MEDs) for comparison. Postoperative Defense and Veterans Pain Rating Scale pain scores (ranging from 0 [no pain] to 10 [worst pain imaginable]) were collected for the first 72 hours postoperatively as a patient-reported means of analyzing effectiveness of analgesia.
A total of 28 patients (mean [SD] age, 64.1 [12.3] years; 17 [61%] male) were included in the MMA group and 37 (mean [SD] age, 65.0 [11.0] years; 22 [59%] male) in the control group. The number of MEDs administered postoperatively was 10.0 (interquartile range [IQR], 2.7-23.1) in the MMA cohort and 89.6 (IQR, 60.0-104.5) in the control cohort (P < .001). Mean (SD) Defense and Veterans Pain Rating Scale pain scores postoperatively were 2.05 (1.41) in the MMA cohort and 3.66 (1.99) in the control cohort (P = .001). Median number of MEDs prescribed at discharge were 0 (IQR, 0-18.8) in the MMA cohort and 300.0 (IQR, 262.5-412.5) in the control cohort (P < .001).
Conclusions and Relevance
The findings suggest that after free flap reconstruction, MMA is associated with reduced narcotic use at discharge and in the immediate postoperative period and with superior analgesia as measured by patient-reported pain scores. Patients receiving MMA achieved improved pain control, and the number of narcotic prescriptions in circulation were reduced.
