Caffeine in Children With Obstructive Sleep Apnea, Dose Response Study

May 12, 2016 updated by: Samia Khalil, The University of Texas Health Science Center, Houston
The aim of this study is to evaluate whether a smaller dose of caffeine sodium benzoate 10 mg/kg IV is as effective as 20 mg/kg IV in decreasing the number of children who develop post extubation adverse upper airway respiratory events compared to placebo.

Study Overview

Status

Status

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

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

Institutional approval and written informed consent from parents or guardians of healthy children, with obstructive sleep apnea (OSA) and/or with increased end-tidal C02 (sleep related hypoventilation, obstructive hypoventilation or sustained alveolar hypoventilation), confirmed with sleep study, scheduled for elective outpatient or inpatient adeno-tonsillectomy at our hospital, will be obtained. The study will be prospective, randomized, double blinded and placebo controlled. A computer generated randomization list will be used, and the study will be registered with clinical.trials.gov. Written child assent will be obtained from children 7 years and older. Copies of a flyer and an explanation of the study will be provided at the office of all the pediatric ENT surgeons who practice at the Memorial Hermann Hospital OR. The investigators will communicate with the nurses at the surgeons' office and ask them to give the flyer with an explanation of the study to the parents and children on the day they schedule the surgery. The flyer with an explanation of study will be sent to IRB for review and approval. A research assistant will invite parents or guardians in the DSU unit, anesthesia clinic or on the floor to allow their children to be part of the study. Children with OSA and/or increased end tidal C02 (sleep related hypoventilation, obstructive hypoventilation or sustained alveolar hypoventilation), 2-12 years of age, and both genders will be eligible to be part of the study. OSA and its severity will be diagnosed by a preoperative polysomnography. Children with compromised cardiovascular, pulmonary or renal function, those with congenital syndromes, sickle cell disease, history of seizures and those receiving theophylline will be excluded.

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

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
Effects of Caffeine
Time Frame: Immediately after drug administration upto 24 hours
The primary outcome of the study is the number of children who develop adverse postextubation respiratory events, including: 1) airway obstruction, requiring jaw-chin thrust maneuver, or placement of an LMA or endotracheal tube, 2) laryngospasm, requiring continuous positive airway pressure or intervention with a muscle relaxant, 3) apnea, 4) desaturation(defined as a decrease in oxygen saturation <95% while breathing oxygen via mask which is our hospital and PACU nurses standard of care), 5) hypoventilation/ hypercapnia )
Immediately after drug administration upto 24 hours

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
Caffeine Drug Effects
Time Frame: Immediately after drug administration to 24 hours
A secondary outcome of the study will be the incidence of adverse post-extubation respiratory events.
Immediately after drug administration to 24 hours
