Brief Summary:
Both morphine and hydromorphone are pain medications commonly used after surgery. It is thought at our institution that hydromorphone causes less side effects but this has not been studied. We propose to treat our patients with either morphine or hydromorphone and determine how much nausea, vomiting, and itching they have with each drug

Condition or disease Intervention/treatment Phase
Post Operative Pain Drug: Morphine PCA Drug: Hydromorphone PCA Phase 4

Drug: Morphine PCA
Morphine 1mg/mL, dose 1mL, lockout 6 minutes, max 10mL
Other Names:
  • Astramorph PF
  • Duramorph
  • Infumorph

Primary Outcome Measures :
  1. Nausea Assessment by Patient [ Time Frame: 1 hour after surgery, 8 hours after surgery ]
    Nausea scale range: (0 = none, 10 = the worst), ordinal.


Secondary Outcome Measures :
  1. Mean Score on the Numeric Rating Scare (NRS) Pruritus Scale [ Time Frame: 1 hour after surgery, 8 hours after surgery ]
    The NRS Pruritus Scale was used to measure magnitude of pruritus (0 = none, 10 = the worst).

  2. Pain Assessment by Patient [ Time Frame: 1 hour after surgery, 8 hours after surgery ]
    Numeric Rating Scale for Pain: (0 = none, 10 = the worst), ordinal.

  3. The Number of Patients Who Vomited [ Time Frame: 1 hour after surgery, 8 hours after surgery ]
  4. Mean Score on the Ramsey Scale of Sedation [ Time Frame: 1 hour after surgery, 8 hours after surgery ]
    The Ramsey scale is used as a measure of sedation from 1 (the patient in anxious and agitated) to 6 (the patient exhibits no response).
