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.

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.

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
Heart Rate (HR)
Time Frame: Heart rate was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. Heart rate was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU).
beats per minute (bpm)
Heart rate was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. Heart rate was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU).
Systolic Blood Pressure (SBP)
Time Frame: Systolic blood pressure (SBP) was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. SBP was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU).

mmHg

Two subjects with missing data points for SBP were necessarily eliminated from repeated measures analysis.
Systolic blood pressure (SBP) was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. SBP was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU).
Diastolic Blood Pressure (DBP)
Time Frame: Diastolic blood pressure (DBP) was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. DBP was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU).

mmHg

Three subjects with missing data points for DBP were necessarily eliminated from repeated measures analysis.
Diastolic blood pressure (DBP) was measured immediately prior to study drug injection (baseline) and every minute thereafter for 5 minutes. DBP was also measured upon the patient's arrival to the Post-Anesthesia Care Unit (PACU).

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
Incidence of Emergence Agitation (EA)
Time Frame: The highest PAED score for each patient within the first 30 minutes after waking up was recorded.
Using a Pediatric Anesthesia Emergence Delirium (PAED) score, emergence agitation scores will be recorded. The PAED score consists of 5 different criteria which are assessed from 0 to 4 once the patient has woken up. These criteria are then totaled; the total may range from 0 to 20, where 0 represents no emergence agitation and 20 represents maximal agitation. For this study, patients with a maximum PAED score of >10 and >12 were considered to be agitated.
The highest PAED score for each patient within the first 30 minutes after waking up was recorded.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

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.
