Management of Pain Post Hepatectomy : Infiltration of Local Anesthetics Versus Continuous Spinal Analgesia .

Analgesia in liver surgery is a challenge, postoperative coagulopathy risk raises fears an epidural haematoma formation following the epidural analgesia, "gold standard" in major abdominal surgery. The spinal analgesia and/or continuous wound infiltration of local anesthetics constitute so an alternative. The study will compare the continuous infiltration of local anesthetics and rachianalgesia in terms of decreased postoperative morphine consumption and incidences of chronic postoperative pain at 3 and 6 months after hepatic surgery compared to the control group.
