The Effect of Different Dose of Ketamine With Low Dose Rocuronium in Children

January 4, 2016 updated by: Go Un Roh, Ajou University School of Medicine

The Effect of Different Doses of Ketamine on Tracheal Intubating Conditions Using Low Dose Rocuronium in Children

Rocuronium is suitable for rapid induction within 60-90 seconds and its effect last 24-40 minute after single bolus injection. For outpatient surgery with short operation time, low dose rocuronium is frequently used for rapid recovery at the expense of compromised intubating condition. For better intubating condition, ketamine can be used. However, appropriate dose of ketamine with low dose rocuronium is not established yet. This study, 3 different doses of ketamine with low dose rocuronium will be compared for appropriate intubating condition.

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.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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
Intubation Condition
Time Frame: during and after intubation, about 2 minute

5 variables will be individually evaluated though 3 point scale (excellent, good, poor). If all variables are graded as excellent, intubation condition will be excellent. If at least 1 variable is poor, it will be reported as poor. Otherwise, it will be reported as good.

  1. Laryngoscope easiness
  2. Vocal cord position
  3. Vocal cord movement
  4. Movement of limb
  5. Coughing
during and after intubation, about 2 minute

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.
