Advantage of Tramadol in Local Analgesia Post-Sternotomy

• Status: Completed
• Trial end date: 2016-10-01
• Target enrollment: 0
• Participant gender: All

Summary

Sternotomy, the reference approach for heart surgery, may induce profound and intense post-operative pain. One method of analgesia used is patient-controlled intravenous morphine.

The analgesic efficacy of continuous wound infiltration at the sternum following heart surgery has been demonstrated.

The analgesic catheter placed near the sternotomy wound reduces the consumption of morphine.

The aim of this study is to determine whether a bolus of tramadol associated with the continuous administration of levobupivacaine via the wound catheter could potentiate the local anaesthetic effects, thus leading to a decreased consumption of postoperative intravenous morphine, and a decrease in morphine-related side effects.

• Phase: Phase 4
