Utility of Abdominal Ultrasound in the Evaluation of Children With Blunt Trauma

January 15, 2019 updated by: University of California, Davis

The major goal of this project is to conduct a randomized controlled trial studying an initial evaluation strategy with abdominal ultrasound versus a strategy without abdominal ultrasound for the evaluation of children with blunt abdominal trauma. The proposal's objectives are to compare the following variables in those that randomize to abdominal ultrasound versus those that do not:

  1. rate of abdominal CT scanning
  2. time to emergency department disposition
  3. the rate of missed/delayed diagnosis of intra-abdominal injury
  4. the costs.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
925

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

No older than 18 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Blunt torso trauma resulting from a significant mechanism of injury

    • Motor vehicle collision: greater than 60 mph, ejection, or rollover
    • Automobile versus pedestrian/bicycle: automobile speed > 25 mph
    • Falls greater than 20 feet in height
    • Crush injury to the torso
    • Physical assault involving the abdomen
    • Decreased level of consciousness (Glasgow Coma Scale score < 15 or below age-appropriate behavior) in association with blunt torso trauma

  • Blunt traumatic event with any of the following (regardless of the mechanism):

    • Extremity paralysis
    • Multiple long bone fractures (e.g., tibia and humerus fracture)
  • History and physical examination suggestive of intra-abdominal injury following blunt torso trauma of any mechanism (including mechanisms of injury of less severity than mentioned above)

Exclusion Criteria:

  • No concern for inter-abdominal injury or no planned evaluation for possible IAI
  • Prehospital or ED age adjusted Hypotension
  • Prehospital or initial ED GCS score ≤ 8
  • Presence of an abdominal "seat belt sign" - continuous area of erythema/contusion completely across the lower abdomen secondary to a lap belt
  • Penetrating trauma: stab or gunshot wounds
  • Traumatic injury occurring > 24 hours prior to the time of presentation to the ED
  • Transfer of the patient to the UCDMC ED from an outside facility with abdominal CT scan, diagnostic peritoneal lavage, or laparotomy previously performed
  • Patients with known disease processes resulting in intraperitoneal fluid including liver failure and the presence of ventriculoperitoneal shunts

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

No Intervention: No Abdominal Ultrasound

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
Time Frame
Rate of Abdominal CT Scan
Time Frame: One week from enrollment
One week from enrollment

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
Time Frame
Total time spent in the Emergency Department
Time Frame: 24 hours from enrollment
24 hours from enrollment
Cost effectiveness
Time Frame: two months from enrollment
two months from enrollment

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
