TRANSIT: Effect of Naloxegol on Postoperative Ileus in Patients Undergoing Cardiac Surgery
Study Details
Study Description
Brief Summary
Postoperative ileus, defined as the transient postoperative functional inhibition of propulsive bowel activity, commonly occurs in patients after cardiac surgery and contributes to postoperative morbidity.
Naloxegol is a peripheral opioid receptor antagonist. Recent studies showed that naloxegol is effective in the treatment of chronic opioid-induced constipation but there is no data on its use in the management of postoperative ileus after cardiac surgery.
The main objective of this prospective, double-blind, randomized, placebo-controlled trial is to assess the effectiveness of the perioperative use of naloxegol in reducing the duration of the postoperative ileus in patients undergoing cardiac surgery.

Detailed Description
Digestive complications following cardiac surgery, such as paralytic ileus and Ogilvie syndrome, are frequent and worsen the prognosis of patients. They pose a real problem of care in intensive care, inducing morbidity and mortality, extended hospital stay and a significant post-operative cost.
Few treatments are effective to reduce transit recovery time, except the neostigmine which has a serious side effects including cardiac ones.
During cardiac surgery, opioid treatments are frequently used to relieve the pain like sternotomy pain.
The pharmacologic effect of opioid induces the postoperative uleus. Opioid receptors are distributed in the central nervous system, where they are involved in the perception of pain, and in the peripheral nervous system, especially in the mesenteric nervous system, where they regulate intestinal peristalsis.
Morphine receptors antagonist are a target for prevention and treatment of post operative ileus syndrome such as alvimopan and naloxone.
A therapeutic trial demonstrates a decrease in the rate of pneumonia in intensive care patient mechanically ventilated who received naloxone.
Naloxegol is a peripheral antagonist of opioid receptor, from the alvimopan family. It has been designed to antagonize the peripheral, but not central, effects of opioids at therapeutic doses. Naloxegol is a substrate for cytochrome P450 (CYP 3A4). Following oral administration, naloxegol is absorbed rapidly, with peak concentrations achieved at less than 2 hours.
After once daily administration, plasma concentration equilibrium is reached within 2-3 days with minimal accumulation.
The main route of elimination for naloxegol is hepatic. Naloxegol has been shown to be effective in randomized trials of chronic opioid induced constipation, but there is no data on its use in the postoperative ileus.
Research hypothesis: the addition of naloxegol in pre and postoperative cardiac surgery could reduce the time to transit recovery and the rate of digestive and respiratory complications.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Naloxegol group naloxégol tablet by oral route |

| Placebo Comparator: Placebo group inert tablet by oral route |
Drug: inert tablet
one inert tablet will be administrated 2 hours before surgery. One inert tablet per day will be administrated from 24h post-surgery until bowel movement; for maximum 5 days.
