Perioperative outcomes of patients with restless legs syndrome: a single-center retrospective review.

STUDY

OBJECTIVES

There are multiple stressors in the perioperative period for patients with restless legs syndrome (RLS) that may be implicated in the worsening of symptoms. Our primary objective was to compare the perioperative course of patients with RLS to patients without the diagnosis.

METHODS

This was a single-center, matched-cohort, retrospective chart review of patients with RLS undergoing inpatient procedures from 2015-2019 matched 1:1 with patients without the diagnosis.

RESULTS

Patients with RLS had a higher comorbidity burden; specifically, pulmonary, renal, diabetes mellitus, and congestive heart failure. The perioperative course was notable for higher maximum pain scores for patients with RLS in the postanesthesia care unit (odds ratio, 1.29; 95% confidence interval, 1.19-1.40; P < .001). Postoperative patients with RLS also had higher maximum pain scores on postoperative days 0, 1, and 2. The odds of rapid-response calls were higher in patients with RLS (odds ratio, 1.43; 95% confidence interval, 1.18-1.73; P < .001). There were no other significant differences in postoperative complications. The odds of using RLS-triggering medications were lower in the RLS group (odds ratio, 0.85; 95% confidence interval, 0.78-0.92; P < .001).

CONCLUSIONS

Our single-center retrospective review found that patients with RLS had higher pain scores in the postanesthesia care unit and on the first few postoperative days. Rapid-response team calls were more common in patients with RLS. RLS-triggering medications were significantly less likely to be used in patients with RLS. There were no significant differences in other postoperative events.
