Abstract:
Background:
Post anesthesia care units (PACU) await return of motor function in lower extremities, prior to discharge for patients undergoing spinal anesthesia. The purpose of this study was to assess the impact of a newly utilized recovery protocol that facilitated early discharges of patients undergoing total hip and knee arthroplasties (THA/TKA) to the floor before full motor recovery from spinal anesthesia is achieved.
Methods:
A total of 647 patients undergoing spinal anesthesia for primary THA (n = 190) and TKA (n = 457) were divided into 2 groups: (1) Early PACU discharge group: patients with partial or full motor blockade at discharge. (2) Control PACU discharge group: patients with full motor recovery at discharge. Readiness for discharge was assessed using a modified Aldrete Score system. The primary outcome was incidences of hypotension or rapid responses post-operatively.
Results:
There was no significant difference in the incidence of hypotension between the two groups (1.4 versus 1.39%, P = 1.0) and zero rapid responses were noted. Early discharge shortened mean PACU LOS time from 86.50 minutes to 70.27 minutes (P < .01). There was no difference in the incidence of nausea (0.55 versus 0%; P = .51) ordizziness (2.22 versus 0.35%; P = .09).
Conclusion:
In this retrospective observational study, we found that early PACU discharge did not result in an increase in hemodynamic consequences on the surgical floor. Thus, discharge from PACU can be safely and more expeditiously performed without waiting for return of motor function in patients receiving spinal anesthesia for THA/TKA using a modified Aldrete Score recovery protocol.
