Post-Operative Spinal Block Duration and Pain Relief After Hip Replacement Surgery: Comparing Single-Shot Spinal Ropivacaine and Bupivacaine

Sponsor: University of Turku

View on ClinicalTrials.gov

Summary

This study aims to determine whether isobaric ropivacaine is more suitable than isobaric bupivacaine for spinal anesthesia in outpatient total hip arthroplasty (THA). The study will evaluate whether ropivacaine allows faster recovery of sensory and motor function while still providing adequate surgical anesthesia and postoperative pain control. Additional aims are to assess the effects of the anesthetic technique on same-day discharge rates, postoperative recovery, urinary retention, opioid consumption, and patient satisfaction after outpatient THA.
