Does Total Intravenous Anesthesia With Short-acting Spinal Anesthetics in Primary Hip and Knee Arthroplasty Facilitate Early Hospital Discharge?

Introduction: Our study assessed the effect of total intravenous anesthesia (TIVA) with short-acting spinal anesthesia and aggressive day-of-surgery postoperative day 0 physical therapy (POD#0 PT) on hospital length of stay (LOS) in patients who underwent primary total joint arthroplasty.

Methods: A retrospective chart review compared the hospital LOS of 116 patients who underwent primary total hip arthroplasty and total knee arthroplasty with TIVA and short-acting spinal blockade ("Updated protocol group") with that of the control group of 228 patients who were under standard anesthesia ("Traditional protocol group").

Results: Both total hip arthroplasty and total knee arthroplasty patients in the Updated protocol group had markedly reduced LOS compared with those in the Traditional protocol group (1.5 ± 0.1 days versus 2.4 ± 0.1 days; P < 0.05 and 1.4 ± 0.1 days versus 2.3 ± 0.1 days; P < 0.05). A higher proportion of patients in the Updated protocol group received at least 1 POD#0 PT session compared with those in the Traditional protocol group.

Conclusion: Total intravenous anesthesia combined with short-acting spinal anesthetics provided the following benefits for patients who underwent primary total joint arthroplasty: more day-of-surgery PT sessions and earlier discharge by nearly 1 full day.

Level Of Evidence: III.
