Laryngeal Mask Airways Are Supraglottic Devices Used to Maintain Airway Patency During Anesthesia and in Difficult Airways. IV Dexmedetomidine Improves LMA Insertion Success and Decreases Coughing, While IV Lidocaine Decreases Postoperative Cough. (DEX LMA)

May 8, 2026 updated by: Abdelrahman Hamdy Mohammed, Assiut University

Intravenous Dexmedetomidine Vs. Lidocaine for Laryngeal Mask Insertion Conditions In Pediatric Patients Undergoing Elective Surgeries, A Randomized Controlled Trial.

Laryngeal Mask Airways Are Supraglottic Devices Used to Maintain Airway Patency During Anesthesia and in Difficult Airways. LMA may help in reducing postoperative pulmonary complications. IV Dexmedetomidine Improves LMA Insertion Success and Decreases trials number, While IV Lidocaine Decreases Postoperative Cough. This is a randomized interventional trial comparing both drugs. IV DEX will be compared vs IV lidocaine regarding the feasibility of insertion, number of trials, incidence of cough, postoperative pulmonary complications and hemodynamic profile.

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.

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.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

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
First-attempt insertion success rate
Time Frame: After induction of anesthesia
The success of the first trial of classic LMA insertion will be assessed. Binary: yes or no.
After induction of anesthesia

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.
