Utstein style study of cardiopulmonary bypass after cardiac arrest

Extracorporeal Cardiopulmonary Resuscitation for Patients With Out-of-Hospital Cardiac Arrest of Cardiac Origin

“…We performed post hoc analysis of the previously published, prospective observational study (12). The present study received approval from our institutional review board.…”

“…The only evidence in the out-of-hospital population was derived from our nonrandomized observational study (12), which contained unbalanced possible confounders such as age, location of arrest, witness status, bystander GPR, initial cardiac rhythm, and cardiac arrest time and GPR duration.…”

Part 8: Advanced Life Support

“…One study demonstrated a 3-month survival of 22.7% for ECPR during out-of-hospital cardiac arrest unresponsive to advance life support after 20 minutes, with 10.6% having a Cerebral Performance Category (CPC) of 1 (LOE 2). 270 However, the ECPR group was more likely to have had a witnessed arrest, received bystander CPR, and be younger (with a mean age of 52 years, compared with 70 years in the standard treatment group).…”

“…Three studies documented improvement in outcome in patients Ͻ70 years old, without significant comorbid conditions and with potential reversible/correctable conditions, when using ECMO compared with traditional CPR (LOE 2 269,270 ; LOE 3 271 ). One study demonstrated a 3-month survival of 22.7% for ECPR during out-of-hospital cardiac arrest unresponsive to advance life support after 20 minutes, with 10.6% having a Cerebral Performance Category (CPC) of 1 (LOE 2).…”

Actual treatments for out‐of‐hospital ventricular fibrillation at critical care medical centers in Osaka: a pilot descriptive study

“…Some hospitals provided treatments far beyond that recommended by the CPR guidelines, whereas some provided less treatment than recommended. Advanced treatments such as ELS, PCI, and TH have been recommended for persistent VF patients, 16,17 but, to our knowledge, few studies have investigated in detail the actual condition of treatments for shock-resistant VF patients covering a certain population.…”
