Interventions and Outcome Measures

Arms

active comparator: Methylnaltrexone Bromide

placebo comparator: Placebo

Interventions

Methylnaltrexone Bromide

The experimental group will receive the recommended dose of MNTX (Relistor) is 8 mg for patients weighing 38 kg to less than 62 kg (84 lbs to less than 136 lbs) or 12 mg for patients weighing 62 kg to 114 kg (136 lbs to 251 lbs). Patients whose weight is below 38 kg or greater than 114 kg, will be dosed at 0.15 mg/kg. If creatinine clearance <30 will decrease dose by 50%. This will be given after 72 hours of no bowel movement. Bowel management protocol will be instituted four hours afterward with the methylnaltrexone being given every other day.

Placebo-Normal Saline

Control group will be given an equal amount of normal saline in an identically appearing vial every other day until a bowel movement occurs. A bowel management protocol will also be started.

Primary outcome measure

  • A significantly higher incidence of a rescue free laxation with methylnaltrexone within 4 hours +- 45 minutes. [ Time Frame: Nine months ]
