Blinded study using oral gabapentin in load pre-operative (15mg/kg) and maintenance 5mg/kg three times a day (TID) for 5 days or discharge, Patient Controlled Analgesia (PCA) morphine and placebo group with similar pills, also PCA morphine. The goal is to measure morphine usage and incidence of morphine side effects (pruritis, days foley, days to first stool, sedation, pain scores, PCA use).

Primary Outcome Measures:
  • Amount of Morphine Consumed (mg/kg/hr) [ Time Frame: PARU (Postanesthesia Recovery Unit - participants typically remain in PARU for 1 hour) ] [ Designated as safety issue: No ]
    Patients are taken to the PARU immediately after surgery, and typically remain for a period of 1 hour.

  • Amount of Morphine Consumed (mg/kg/hr) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Amount of Morphine Consumed (mg/kg/hr) [ Time Frame: Day 2 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Side Effect Occurrence [ Time Frame: First 10 days after surgery ] [ Designated as safety issue: No ]
    The number of episodes of/occurrence of side effects was monitored in both groups.
