The aim of this study is first to assess if desflurane is superior in order to achieve a faster emergence from anesthesia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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 first to assess if desflurane is superior in order to achieve a faster emergence from anesthesia (stating the date of birth) and second if desflurane is non-inferior in the occurrence of airway complications compared to sevoflurane or total intravenous anesthesia with propofol in the setting of laryngeal mask airway.

Study Type

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
Measure Description
Time Frame
time of emergence from anesthesia
Time Frame: up to 15 minutes
time of emergence from anesthesia defined as time between cessation of anesthesia until patient is able to state his/her date of birth on command
up to 15 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
Airway reactions (Incidence of intraoperative coughs, laryngospasm)
Time Frame: up to 2 hours
Incidence of intraoperative coughs (induction/maintenance) - non-inferiority design Incidence of intraoperative laryngospasm (induction/maintenance) Incidence of cough at emergence Incidence of laryngospasms at emergence
up to 2 hours
Emergence times
Time Frame: up to 15 minutes
Time to remove laryngeal mask Time to open eyes on command Time to respond on command (press hand) Time to state the name on command Recovery Index (RI = 1 + Aldrete5min/[(2xextubation time) + 1 x opening eyes time)]
up to 15 minutes
