Intervention model description: Will create a double blind, randomized, parallel design study to evaluate the effectiveness of Alvimopan(post operative dose) in preventing post-operative ileus in poly-traumatized patients
Primary purpose: PREVENTION

Brief summary: To evaluate the efficacy and safety of Alvimopan(12 mg) in recovery of bowel function in an emergency trauma setting without the pre-operative dosage in patients that will receive abdominal surgery.


Eligibility criteria: Inclusion Criteria:

* Ages 18 to 80
* Poly-traumatized patients
* Extubated patients after abdominal exploration
* Underwent Abdominal exploration, had colon resection with primary anastomosis with closure of abdomen

Exclusion Criteria:

* Mechanically ventilated patients
* Patient not expected to survive Glasgow Coma Scale = 3
* Pregnant patients
* Apache score \> 40 (observed mortality 100%) Saas Ahmed Naved et al 2011
* Vasopressor therapy
* Septic patients
* Thoracotomy
* Bogota bag
* Intravenous Drug Abuser (IVDA) as evidenced by urine toxicology upon admission to the Trauma Unit
* Patients with prior history of gastric surgery and/or colonic surgery
* Medical History: of severe cardiovascular disease, Renal diseases, Hepatitis C or Hepatic failure, Autoimmune disease, Crohn and Ulcerative Colitis (In view of the inflammation in the intestinal mucosal which may decrease optimal absorption of the medication) and or bowel obstruction
* Prior pancreatic anastomosis or gastric anastomosis; ostomy formation
* Chronic use of nonsteroidal anti-inflammatory drugs

Primary outcomes:
measure: Recovery of bowel function in trauma patients who received post operative dose of Alvimopan compared to placebo.
timeFrame: 2 years
Secondary outcomes:
measure: Length of stay in patients of the same population who receive a placebo.
timeFrame: 5 years
Other outcomes:
Locations:
city: San Juan
country: Puerto Rico
facility: Puerto Rico Trauma Hospital
