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

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

Detailed Description

Purpose: To investigate the effects of different doses of cisatracurium pretreatment on succinylcholine-induced fasciculations and postoperative myalgia.

Methods: Ninety patients scheduled for laparoscopic cholecystectomies were equally randomized into three groups to receive pretreatment of 0.005, 0.01, and 0.02 mg/kg cisatracurium, respectively. General anesthesia was induced 3.5 min later, train of four stimulation was monitored 4.5 min later, succinylcholine 1.5 mg/kg was injected 5 min later, and endotracheal intubation was implemented 6.5 min later. The side effects of cisatracurium, intensity of fasciculations, intubating conditions, time and extent to maximal depression of twitch and time for its recovery to 20% of control value, severity of myalgia at 24 h postoperatively, serum potassium before the induction, at the time of endotracheal intubation, and 5 min after intubation were recorded.

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
Time Frame
The presence of fasciculations
Time Frame: After the injection of succinylcholine for 1.5 minutes
After the injection of succinylcholine for 1.5 minutes

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
Side effects of the pretreatment of cisatracurium
Time Frame: At the time of three minutes after the pretreatment of cisatracurium

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.
