What is being measured

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

  1. Narcotic Requirement After Surgery

    The primary efficacy end point was narcotic consumption during the first 48 hours after craniotomy. Opioid usage was calculated by converting the amount of the narcotics taken by the patient into oral morphine equivalents (ME), which were totaled for each postoperative day. At 48 hours after surgery, patients who received IV acetaminophen in addition to our standardized pain protocol did not have a statistically significantly lower mean narcotic requirement, measured in ME, when compared with those in the placebo group.

    Measured: 48 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Intravenous acetaminophen in people with Post-operative Craniotomy Patients and Carotid Endarterectomy and Carotid Artery Stenosis Patients, run by University of Utah 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 7 inclusion and 4 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 24 Apr 2023. 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. Some participants in this study may receive a placebo. 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 24 Apr 2023). 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?

Narcotic Requirement After Surgery (time frame: 48 hours). 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 NCT01948505, 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 24 Apr 2023.
