Overview
Brief Summary
Knee arthroplasty has a high potential for postoperative pain. This study compares analgesia and postoperative bleeding from intrathecal morphine with the continuous femoral and a single-shot sciatic nerve blockades.
Detailed Description
This study aims to compare intrathecal morphine as a technique for analgesia with the femoral nerve blockade associated with a single-shot sciatic nerve blockade. Analgesic efficacy, the incidence of adverse effects, and postoperative bleeding were evaluated

Outcomes
Primary Outcomes
Analgesic Efficacy
Time Frame: baseline (zero hour: discharge of post-anesthesia care unit-PACU), 24hs, 48hs, 72 hours
Pain with verbal numeric rating scale (VNRS). VNRS has 11 points, from zero to 10 (zero= no pain, 1-3 = mild pain, 4-5 = moderate pain, 7-9 = severe pain, 10 = unbearable pain).
Secondary Outcomes
- Postoperative Bleeding(baseline (discharge of post-anesthesia care unit-PACU), 24hs, 48hs, 72 hours)
