January 25, 2022 updated by: Matias Vested

An Observational Study of Cisatracurium 0.15 mg/kg, Comparing Onset Time, Duration of Action and Effect on Intubating Conditions in Young (18 - 40 Years) and Elderly (≥ 80 Years) Patients.

The aim of this study is to determine the onset time, duration of action and effect on intubation conditions of cisatracurium 0.15 mg/kg in elderly patients with age ≥ 80 years and in young patients aged 18 - 40 years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 aim of this study is to determine the onset time, duration of action and effect on intubation conditions of cisatracurium 0.15 mg/kg in elderly patients with age ≥ 80 years and in young patients aged 18 - 40 years. The hypothesis of this study is that cisatracurium administered in elderly patients (>80 years) has a longer onset time and duration of action compared to younger patients.

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.

Ages Eligible for Study

18 years to 110 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Elderly
patients aged 80 years or older
Drug: Cisatracurium
0.15 mg/kg based on ideal body weight calculated as height (cm) minus 105 for women and height (cm) minus 100 for men or actual body weight, whichever is lower
young
patients aged 18-40 years
Drug: Cisatracurium
0.15 mg/kg based on ideal body weight calculated as height (cm) minus 105 for women and height (cm) minus 100 for men or actual body weight, whichever is lower

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
Onset time
Time Frame: within 10 minutes after administration
the time from the start of the injection of cisatracurium to train-of-four (TOF) count of 0 monitored by acceleromyography
within 10 minutes after administration

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
Laryngeal morbidity
Time Frame: 24 hours after surgery
After 24 hours patients are asked about hoarseness and sore throat. Patients who experience either or both will be called 3 days postoperatively again. These two variables are assessed using a numeric ranking scale from 0 to 10.
24 hours after surgery
Duration of action
Time Frame: within 120 minutes after administration of cisatracurium
Duration of action is defined as time from start of cisatracurium injection to reappearance of TOF ratio > 0.9.
within 120 minutes after administration of cisatracurium
intubation conditions
Time Frame: within 10 minutes after administration of cistracurium
intubation conditions are rated according to intubating difficulty score IDS when TOF-ratio is 0.
within 10 minutes after administration of cistracurium
intubation conditions
Time Frame: within 10 minutes after administration of cisatracurium
intubation conditions are rated according to Fuchs-Buder score when TOF-ratio is 0.
within 10 minutes after administration of cisatracurium
Amount of ephedrine or metaoxedrine administered
Time Frame: within 10 minutes after administration of cisatracurium
If ephedrine or metaoxedrine is administered after induction of anaesthesia and until the patient is ready for properly positioning for surgery, it will be noted in the CRF, as well as the amount administered. Changes in blood pressure or heart rate are treated according to local guidelines.
within 10 minutes after administration 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.
