As total joint arthroplasty programs continue to move towards same-day discharge (SDD), time to discharge is an increasingly important performance indicator. The primary objective of this study was to determine the impact of the choice of anesthetic on the time to discharge after SDD primary hip and knee arthroplasty. A retrospective chart review was conducted within our SDD arthroplasty program, with 261 patients identified for analysis. Baseline characteristics, length of surgery, anesthetic drug, dose, and perioperative complications were extracted and recorded. The time from the patient leaving the operating room to physiotherapy assessment and from the operating room to discharge were recorded. These were referred to as ambulation time and discharge time, respectively. The ambulation time was significantly reduced when hypobaric lidocaine was used in a spinal block compared to isobaric or hyperbaric bupivacaine—135 minutes (range, 39 to 286), 305 minutes (range, 46 to 591), and 227 minutes (range, 77 to 387), respectively—(P < .0001). Similarly, the discharge time was also significantly lower with hypobaric lidocaine compared to isobaric bupivacaine, hyperbaric bupivacaine, and general anesthesia—276 minutes (range, 179 to 461), 426 minutes (range, 267 to 623), 375 minutes (range, 221 to 511), and 371 minutes (range, 217 to 570), respectively—(P < .0001). No cases of transient neurologic symptoms were reported. Patients receiving a hypobaric lidocaine spinal block experienced significantly reduced ambulation time and time to discharge compared to other anesthetics. Surgical teams should feel confident in using hypobaric lidocaine during spinal anesthesia as it is rapid and efficacious.
