October 15, 2014 updated by: Feray Erdil, Inonu University

Turgut Ozal Medical Center Department of Anesthesiology and Reanimation

The investigators evaluate the effects of a subanesthetic dose of ketamine, administered as an adjunct to sevoflurane, on duration of seizure activity, hemodynamic profile and recovery times during electroconvulsive therapy (ECT) in patients with major depression.

Study Overview

Status

Status

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

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 will randomly allocate, to either a sevoflurane-ketamine (Group SK), sevoflurane-saline (Group SS) receiving group. Mean arterial pressure (MAP) and heart rate (HR) will record prior to anesthetic induction (T1); following anesthetic induction (T2); and 0, 1, 3, and 10 min after the seizure has ended (T3, T4, T5, and T6, respectively). Motor and EEG seizure durations will be recorded.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Group SK
Sevoflurane was initiated, in both groups, at 8% for anesthesia induction until loss of consciousness was achieved, at which point it was discontinued. Following loss of consciousness ketamine was administered to Group SK (n=29) in the form of a 0.5mg/kg iv bolus. Patients in Group SS (n=30) received saline in the same manner.
Drug: Sevoflurane
Inhalation anesthetic agent
Other Names:
  • Sevoflurane (sevorane)
Drug: Ketamine
Intravenous anesthetic agent
Other Names:
  • Ketamine (Ketalar) 50mg/mL injection
Placebo Comparator: Group SS
Sevoflurane was initiated, in both groups, at 8% for anesthesia induction until loss of consciousness was achieved, at which point it was discontinued. Patients in Group SS (n=30) received saline in the same manner.
Drug: Sevoflurane

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
seizure duration
Time Frame: During electroconvulsive therapy (30 minutes)
the time from application of the ECT stimulus to the cessation of tonic-clonic motor activity in the isolated arm.
During electroconvulsive therapy (30 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
Measure Description
Time Frame
Mean arterial pressure (MAP)
Time Frame: During Electroconvulsive therapy (30 minutes)
Mean arterial pressure (MAP) will be recorded prior to anesthetic induction (T1); following anesthetic induction (T2); and 0, 1, 3, and 10 min after the seizure has ended (T3, T4, T5, and T6, respectively).
During Electroconvulsive therapy (30 minutes)
Heart rate (HR)
Time Frame: During Electroconvulsive therapy (30 minutes)
Heart rate (HR) will be recorded prior to anesthetic induction (T1); following anesthetic induction (T2); and 0, 1, 3, and 10 min after the seizure has ended (T3, T4, T5, and T6, respectively).
During Electroconvulsive therapy (30 minutes)

Primary Completion (Anticipated)

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.
