Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of our study was to evaluate the clinical value of preventive treatment EXACYL® on bleeding during surgery to orthognathism. Our hypothesis is that this preventive treatment is not enough reduces bleeding to cause a change in patient management (count additional blood count, extra padding, transfusion).

Prospective equivalence trial type controlled by two parallel group, randomized, triple-blind (patient, surgical team, anesthesia team).

  • EXACYL® Group: 1 syringe 1g EXACYL® on one hour + 1 syringe 1g EXACYL® on 8 hours
  • Control group: 1 syringe 30 mL of saline on one hour + 1 syringe 30 mL saline on 8 hours Main criteria is amount of blood during the entire hospitalization: bleeding during surgery completed in the amount of blood present in the suction drains and nasogastric tube until ablation thereof.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

8 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
bleeding perioperative
Time Frame: discharge from the hospital between 2 and 5 days
bleeding during surgery and bleeding after surgery until hospitalization discharge
discharge from the hospital between 2 and 5 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
bleeding during surgery
Time Frame: end of the surgery
Amount of blood during surgery including : blood in the surgical aspiration, in compresses ( assessed by weighing compresses ) in the anesthetic aspiration (when extubation ) and the nasogastric tube at the end of surgery
