Randomized, Controlled Trial Comparing the Effectiveness of Sedation-Epidural Anesthesia to Spinal Anesthesia in Outpatient Hip or Knee Arthroplasty.

To our knowledge, no study has compared the difference between these two NA techniques. Early postoperative adverse events like uncontrolled pain, orthostatic hypotension, urinary retention, and prolonged motor block are linked to late patient mobilization, prolong hospitalization and failure to discharge in outpatient setting. The type of anesthesia used may have an important impact. Therefore, this study has the potential to improve the already established ERAS program and improve patients care perioperative and postoperative. Showing that SED-EA and SA are equivalent will allow for a more efficient and reliable technique for THA/TKA ERAS program that can be further translated into other lower limb surgeries.
