About this study

Official title: A Comparison of Two Target Mean Arterial Pressures in the Resuscitation of Hypotensive Trauma Patients Undergoing Laparotomy or Thoracotomy for Trauma: A Prospective Randomized Controlled Clinical Trial

The goal of this study will be to determine if a lower than normal blood pressure during surgery for bleeding in the abdomen or chest will result in decreased bleeding and decreased chance of death.

Read the detailed description

For the proposed study, all trauma patients undergoing laparotomy or thoracotomy for trauma that had a systolic blood pressure < 90 mmHg prior to going to the operating room will be randomized to one of two groups. The randomization will take place at the operating room door. The first group will have a target minimum mean arterial pressure of 50 mm Hg (LMAP) and the second group will have a target minimum mean arterial pressure of 65 mmHg (HMAP). Before the operating room and in all other aspects of their care the patients will be treated as per standard of care. Patients will then be followed to determine if there is a difference in 30 day survival between the two groups. Secondary outcome measures will be Sequential Organ Failure Assessment (SOFA) score, APACHE II, ARDS, ICU length of stay, myocardial ischemia, stroke, acidosis, coagulopathy by conventional labs and thromboelastogram, estimated blood loss, transfusion requirements, Glasgow Outcome Score, the presence of leukocyte apoptosis, the serum level of the pro-inflammatory cytokines, IL-6 and G-CSF, and the rate of infectious complications (VAP, UTI, Wound infections). Blood samples (20 ml each) will be taken at three time points: prior to randomization, immediately after the end of resuscitation protocol, and 24 hrs after randomization. Blood will be examined for the presence of leukocyte apoptosis and levels of IL-6 and G-CSF.

Questions about this trial

What is this clinical trial studying?

A study testing Intraoperative Hypotensive Resuscitation in people with Hemorrhagic Shock and Trauma, run by Baylor College of Medicine 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 1 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 1 Dec 2010. 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.

Are results available for this study?

Results are not available in the source record.

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

Contact Matthew M Carrick, MD (713-873-4381, mcarrick@bcm.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

30 day survival (time frame: 30 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Dec 2010.
