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.

Outcome Measures

Primary Outcomes (1)

  • Analgesic Efficacy

    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).

    baseline (zero hour: discharge of post-anesthesia care unit-PACU), 24hs, 48hs, 72 hours

Secondary Outcomes (1)

  • Postoperative Bleeding

    baseline (discharge of post-anesthesia care unit-PACU), 24hs, 48hs, 72 hours

Study Arms (2)

femoral blockade

EXPERIMENTAL

femoral nerve blockade followed by a catheter placement for continuous infusion and a "single shot" block of the sciatic nerve

Procedure: femoral nerve blockade

Morphine

ACTIVE COMPARATOR

intrathecal morphine

Procedure: morphine

Interventions

femoral nerve blockade followed by a catheter placement for continuous infusion and a "single shot" block of the sciatic nerve at the end of the surgery

femoral blockade
morphinePROCEDURE

Intrathecal morphine injection

Morphine
