July 16, 2013 updated by: Kyo-Sang Yoo, Hanyang University

Comparison Between Continuous Infusion and Intermittent Bolus Injection of Propofol for Deep Sedation During Endoscopic Retrograde Cholangiopancreatography: a Prospective Randomized Controlled Study

The aim of this study is to compare sedation efficiency, safety and satisfaction by both endoscopist, assistants, and the patients between continuous infusion and intermittent bolus injection of propofol for deep sedation during ERCP.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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 patients undergone ERCP were randomly assigned to either continuous infusion of propofol (continuous group) or midazolam plus intermittent bolus injection of propofol (intermittent group) for deep sedation. In the continuous group, propofol was continuously administered via infusion pump and the doses were determined by sedation assistants monitoring the patients. In the intermittent group, a loading dose of 2 mg of midazolam and 0.4 mg/kg of propofol was initially injected and repeated bolus injection of 20 mg of propofol was followed according to patients' sedation level. Sedation related parameters (total dose of propofol, induction/recovery time, patients' cooperation) and adverse events during the procedure were evaluated. Satisfaction scores by endoscopist, assistant, and patients and difficulty scores of maintaining the sedation by assistants were also graded after the procedure.

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.

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
Time Frame
Satisfaction scores by endoscopist
Time Frame: 30 minutes after the procedure
30 minutes after the procedure

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
Adverse events for sedation
Time Frame: 1 day after the procedure
1 day after the procedure
Difficulty scores of maintaining the sedation
Time Frame: 30 minutes after the procedure
