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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Autistic children appear with significant frequency for medical services, lots of which requiring procedural sedation or anaesthesia. They have often been described as difficult to sedate or anesthetize due to a variety of ASD symptoms. It is a challenging task to provide safe and effective sedation during the colonoscopic procedure in autism children. Propofol sedation for endoscopic procedures is safe and acceptable for children, especially those who express significant anxiety. Propofol-based sedation turned out to be the most effective dosage regimens, with effectiveness comparable to general anesthesia. The addition of certain dose ketamine to propofol may increase the effectiveness without creating more adverse events.

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

  • Child

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
Dose of Propofol Required to Prevent Movement (Response) to Insertion of colonoscpopy 1
Time Frame: Procedure (This outcome is measured at the time of insertion of colonoscopy)
The objective is to determine the effective bolus dose in 50% of subjects (ED50) of propofol in combination with ketamine 0.3, 0.6mg/kg that produces an adequate depth of anesthesia to prevent minimal or no movement on colonoscopy insertion in children with Autism spectrum disorder.
Procedure (This outcome is measured at the time of insertion of colonoscopy)
Dose of Propofol Required to Prevent Movement (Response) to Insertion of colonoscpopy 2
Time Frame: Procedure (This outcome is measured at the time of insertion of colonoscopy)
The objective is to determine the effective bolus dose in 95% of subjects (ED50) of propofol in combination with ketamine 0.3, 0.6mg/kg that produces an adequate depth of anesthesia to prevent minimal or no movement on colonoscopy insertion in children with Autism spectrum disorder.
Procedure (This outcome is measured at the time of insertion of colonoscopy)

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
movement score during the procedure
Time Frame: during the procudure
(1 = no movement; 2 = semipurposeful allowing continuation of the procedure; 3 = vigorous purposeful movements withholding the procedure)
during the procudure
arterial blood pressure
Time Frame: during the procudure
arterial blood pressure was measured noninvasively at four time points:T0: before induction of sedation,T1: immediately after induction of sedation, T2: complete evaluation of the coln through colonoscopy, T3: at the end of colonic TET procedure。
during the procudure
adverse event
Time Frame: during the procedure - 24 hours after procedure
(including hypoxia (SpO2 <93% for >10 s) or respiratory depression (apnea >15 s), hypotension (MAP < 20% from baseline) or bradycardia (HR < 60 x/min and/or decrease in HR > 20% from baseline) were recorded.
during the procedure - 24 hours after procedure
