A Comparison of the Effect of Interposed Abdominal Compression Cardiopulmonary Resuscitation and Standard Cardiopulmonary Resuscitation Methods on End‐tidal CO₂ and the Return of Spontaneous Circulation Following Cardiac Arrest: A Clinical Trial

Abstract

Objectives: Sudden cardiac arrest is a major cause of death in the adult population of developed countries, with only 10%-15% of cardiopulmonary resuscitations (CPRs) being successful. We aimed to compare the effects of interposed abdominal compression CPR (IAC-CPR) with standard CPR (STD-CPR) methods on end-tidal CO 2 (ETCO 2 ) and the return of spontaneous circulation (ROSC) following cardiac arrest in a hospital setting.Methods: After cardiac arrest was confirmed in a patient at Mashhad Ghaem Hospital, 80 cases were randomly assigned to one of the two methods of resuscitation, either IAC-CPR or STD-CPR, respectively. The inclusion criteria for the study were nontraumatic cardiac arrest, in patients between the age of 18 and 85 years, and the presence of endotracheal tube. Exclusion criteria were abdominal surgery in the past 2 weeks, active gastrointestinal bleeding, pulmonary embolism, and suspected pregnancy.Results: There was a significant difference between the two groups in ETCO 2 (p < 0.003), but there was no significant difference as far as the ROSC (p > 0.50). Conclusion:The increase in the ETCO 2 during IAC-CPR is an indicator of the increase in cardiac output following the use of this method of CPR.ACADEMIC EMERGENCY MEDICINE 2016;23:448-454

Standard CPR versus interposed abdominal compression CPR in shunted single ventricle patients: comparison using a lumped parameter mathematical model

“…This is concordant with a recent adult trial in which IAC-CPR increased end-tidal CO 2 , a surrogate measure of cardiac output, by 38% versus standard CPR. 23 The 19% increase in diastolic blood pressure demonstrated during IAC-CPR improved hemodynamic profilesthere was an increase in coronary perfusion pressure (13%) and coronary blood flow (17%) in the Blalock-Taussig-Thomas shunt model, and in the Sano model (coronary perfusion pressure increased 19%, coronary blood flow increased 14%). These virtual findings are consistent with the known physiologic effects of IAC-CPR seen in animal studies and human trials of the resuscitation technique.…”

Comparison Between Active Abdominal Compression-Decompression Cardiopulmonary Resuscitation and Standard Cardiopulmonary Resuscitation in Asphyctic Cardiac Arrest Rats With Multiple Rib Fractures

“…In more severe instances, it can lead to asphyxial CA or ventricular fibrillation CA, necessitating cardiopulmonary resuscitation to save lives. However, despite the widespread use of STD-CPR, the survival rate after CA remains low (19). The overall survival to discharge from out-of-hospital CA, resuscitated with STD-CPR and advanced life support protocols, is reported to be between 2% and 15% (20), with a neurologically intact survival rate between 1.5% and 9.1% (21).…”

Effect of Active Abdominal Compression-Decompression Cardiopulmonary Resuscitation on Oxygen Metabolism and Prognosis in Patients with Cardiac Arrest

“…According to the epidemiological investigation in developed countries, the incidence of CA was still high, but the limitation of external pressure, facial defects, one -sidedness, lack of accurate and effective operation of rescue personnel resulted in a very low ROSC rate [8,9].Chest in STD-CPR can not fully rebound, and not give sufficiently play to the effect of heart lung and lung pump and CPR success rate is limited [10]. Wang Lixiang ' s team based on abdominal CPR, proposes the ALC-CPR new technique for restoring body size by pulling and pressing abdomen [11]; so as to achieve the effect of saving treatment .…”
