Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Thoracic epidural analgesia (TEA) is the gold standard analgesia of the laparotomy in major abdominal surgery and can be associated with intravenous lidocaine or subtituted by intravenous lidocaine when TEA is contraindicated and in order to reduce the use of the morphinics in the perioperative period.

Side effects can be paralytic ileus or nausea and vomiting and delay the enhanced recovery after surgery.

Intravenous lidocaine and TEA share several properties like anti hyperalgesia, anti inflammatory effect, intestinal process, anti tumoral effect… which suggests an additive effect of their combination that was not studied yet.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

thoracic epidural analgesia

Lidocaine will be injected during the anaesthetic induction and infused until the surgical closure (30 minutes before the end), then ropivacaine will be injected in the TEA at the same time and infused during 24h. The occurrence of adverse events will be monitor by a physical examination and blood samples of lidocainemia and ropivacainemia in the perioperative period

Group Type EXPERIMENTAL

Blood sample

Intervention Type OTHER

Lidocaine blood sample 30 min before the end of the surgery Lidocaine blood sample at the end of the infusion lidocaine and ropivacaine blood sample 2 h after the ropivacaine infusion of the TEA Ropivacaine blood sample 24h after the infusion of the TEA

Lidocain

Intervention Type DRUG

Lidocaine will be injected during the anaesthetic induction and infused until the surgical closure (30 minutes before the end) The occurrence of adverse events will be monitor by a physical examination and blood samples of lidocainemia and ropivacainemia in the perioperative period.

ropivacaine

Intervention Type DRUG

Lidocaine will be injected during the anaesthetic induction and infused until the surgical closure (30 minutes before the end), then ropivacaine will be injected in the TEA at the same time and infused during 24h. The occurrence of adverse events will be monitor by a physical examination and blood samples of lidocainemia and ropivacainemia in the perioperative period.
