Background

Post-anesthesia care unit (post-anesthesia care unit) duration after total hip arthroplasty (total hip arthroplasty) is relevant for ward transfer, early mobilization, and perioperative flow, but is inconsistently reported as a distinct recovery outcome.

Purpose

This study evaluated post-anesthesia care unit duration after primary total hip arthroplasty under spinal anesthesia in routine hospital-based practice and interpreted the observed duration in relation to contemporary arthroplasty literature.

Methods

This retrospective observational cohort study included adult patients undergoing primary total hip arthroplasty under spinal anesthesia within two units of a regional hospital.

n = Ninety-seven of 150 screened

Results

162.3

average time patients spent in the recovery room after hip replacement surgery

n = Ninety-seven of 150 screened

More results

Post-anesthesia care unit duration was numerically longer in Unit A than Unit S, but the difference was not statistically significant.

Reported early recovery endpoints in the literature were heterogeneous.

In univariate analysis, male sex and exploratory spinal local anesthetic dose > 13 mg were associated with longer post-anesthesia care unit duration.

Conclusion · 1 of 3

Post-anesthesia care unit duration after total hip arthroplasty under spinal anesthesia should be interpreted as a multifactorial, workflow-sensitive outcome rather than a purely anesthetic recovery measure.

Conclusion · 2 of 3

Differences in discharge criteria, recovery pathways, and endpoint definitions limit direct comparison across studies.

Conclusion · 3 of 3

post-anesthesia care unit duration may be most meaningful as an operational recovery and flow indicator within broadly comparable clinical settings.
