Comparison of Mg, Ketamine, Large Dose Rocuronium, and Priming on Intubating Condition in Rapid Sequence Intubation

In this study, methods which are known for facilitating rapid sequence intubation or accelerating rocuronium (Roc)onset are compared including magnesium (Mg), ketamine pretreatment, large dose rocuronium and priming.

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

Patients are pretreated with Mg, ketamine, or priming dose Roc. Two groups do not receive pretreatment, but are given Roc 0.6 mg/kg or 0.9 mg/kg.

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.

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 score
Time Frame: participants will be followed at the time point of intubation, an expected average of 70 sec from the start of rocuronium injection.
Patients are tracheally intubated, and intubation scores(poor, good,excellent)are rated.
participants will be followed at the time point of intubation, an expected average of 70 sec from the start of rocuronium injection.

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
Roc duration
Time Frame: participants will be followed when TOF count reaches two, an expected average of 40 min.
Time from the start of rocuronium injection until reappearance of two muscle twitches in TOF stimulations is measured, using ToF-Watch sx.
participants will be followed when TOF count reaches two, an expected average of 40 min.
Roc onset
Time Frame: participants will be followed when TOFcount =0 within an expected average of 4 min from the start of rocuronium injection.
Time from the start of rocuronium injection until TOF count=0 using TOF-Watch sx.
participants will be followed when TOFcount =0 within an expected average of 4 min from the start of rocuronium injection.
Hemodynamic variables
Time Frame: participants will be followed at baseline, before and for 5 min after the intubation, an expected average of 8 min after the start of anesthetic induction.
Mean arterial pressure (MAP)and heart rate (HR) are measured at baseline, before intubation, and 1, 2, 3, 4, 5 min after intubation.
participants will be followed at baseline, before and for 5 min after the intubation, an expected average of 8 min after the start of anesthetic induction.
TOF% at intubation
Time Frame: participants will be followed at the time point of intubation, an expected average of 70 sec from the start of rocuronium injection.
neumeric value expressed as %, displayed on the monitor of TOF watch-Sx in TOF stimulation (ex. 5% on the display means 95% suppression of T1)
participants will be followed at the time point of intubation, an expected average of 70 sec from the start of rocuronium injection.
