Project title: Identification of the Optimal Transthoracic Defibrillation Energy Parameters for Post-Cardiac Arrest Resuscitation in Obese Patients
Human subjects IRB approved project number (where applicable):
Project Type: Retrospective Chart Review Research Study
Brief Description of Project.
The aim of the study is to determine the Optimal Transthoracic Defibrillation Energy Parameters for Post-Cardiac Arrest Resuscitation in Obese Patients.
Defibrillation is recognized as the only effective means for prevention of sudden cardiac death. Defibrillations success and failure is largely trial and error; varying depths of ventricles unique to markedly overweight patients only further exacerbate this subjectivity. Therefore, retrospectively, we hope to determine optimal defibrillation parameters in obese patients during post-cardiac arrest resuscitation by establishing the correlation between obesity and amount of energy necessary/used successfully for resuscitation.
The study is including chart reviews of four hundred obese men and women between the ages of 18 and 80 (obese being defined as body mass index [BMI] of 30 kg/m2) that were admitted to/or treated at Parkland Hospital with transthoracic defibrillation for cardiac arrest.
Patient charts will be reviewed to collect necessary data and to determine eligibility for the study. Parameters to be considered include age; sex; weight and height; diagnosis; treatment modalities while in the hospital (medical, surgical, etc.); cause of cardiac arrest (if known); CPR modalities (if recorded); energy employed during defibrillation; number of times defibrillated, and interval between defibrillation attempts. Final disposition will be categorized as (1) survived, (2) survived with end organ damage, and (3) unsuccessful defibrillation and/or death.
Inclusion Criteria of the subjects: The subject population will include 400 obese (defined by a BMI=30) men and women age 18-80 who were admitted to/or treated at Parkland Hospital for Cardiac arrest, and defibrillated.
Exclusion Criteria of the subjects: Those patients that meet the criteria but did not experience cardiac arrest, or that were not defibrillated.
This is a retrospective study. The charts are collecting through a National database.
Student can actively participate data gathering and evaluation of the data in that study.
