About this study

Official title: The Comparison of Morphine and Hydromorphone Patient-Controlled Analgesia

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

Being tested
Morphine PCA, Hydromorphone PCA
Keywords
pain, morphine, hydromorphone, nausea, vomiting, pruritis
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Morphine PCADrug

    Also called Astramorph PF, Duramorph, Infumorph

    Morphine 1mg/mL, dose 1mL, lockout 6 minutes, max 10mL

  • Hydromorphone PCADrug

    Also called Dilaudid

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nausea Assessment by Patient

    Nausea scale range: (0 = none, 10 = the worst), ordinal.

    Measured: 1 hour after surgery, 8 hours after surgery

Secondary outcomes (4)
  1. Mean Score on the Numeric Rating Scare (NRS) Pruritus Scale

    The NRS Pruritus Scale was used to measure magnitude of pruritus (0 = none, 10 = the worst).

    Measured: 1 hour after surgery, 8 hours after surgery

  2. Pain Assessment by Patient

    Numeric Rating Scale for Pain: (0 = none, 10 = the worst), ordinal.

    Measured: 1 hour after surgery, 8 hours after surgery

  3. The Number of Patients Who Vomited

    Measured: 1 hour after surgery, 8 hours after surgery

  4. Mean Score on the Ramsey Scale of Sedation

    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).

    Measured: 1 hour after surgery, 8 hours after surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Morphine PCA and Hydromorphone PCA in people with Post Operative Pain, run by Columbia University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Aug 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Nausea Assessment by Patient (time frame: 1 hour after surgery, 8 hours after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00385541, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Aug 2018.
