Preoperative optimization and protocols for joint replacement care pathways have led to decreased length of stay (LOS), decreased narcotic use and are increasingly important in delivering quality, cost savings and shifting appropriate cases to an outpatient setting. The intraoperative use of vasopressors is independently associated with increased length of stay, risk of adverse postoperative events including death and in total hip arthroplasty there is an increased risk for ICU admission. Our aim is to characterize the patient characteristics associated with vasopressor use specifically in total knee arthroplasty (TKA). We retrospectively reviewed 748 patients undergoing inpatient primary total knee arthroplasty at a single academic institution by two surgeons from 1/1/17 to 12/21/18. Demographics, comorbidities, perioperative factors and intraoperative medication administration were compared with multivariate regression to identify patients who may require intraoperative vasopressors.INTRODUCTION
