MedicalResearch.com: What is the background for this study? What are the main findings?
Response: For over three decades, paramedics have performed endotracheal intubation (ETI) as the standard advanced airway management strategy in cardiac arrest. However, intubation is a difficult and error-prone intervention. Newer supraglottic airways such as the laryngeal tube (LT) offer easier insertion technique with comparable ventilation. However, intubation and laryngeal tubes have not been tested head-to-head in a randomized trial.
Our study – the Pragmatic Airway Resuscitation Trial (PART) – tested intubation vs laryngeal tube for airway management in adult out-of-hospital cardiac arrests. The trial included 27 EMS agencies from the Birmingham, Dallas-Fort Worth, Milwaukee, Portland and Pittsburgh communities. The trial randomized a total of 3,004 adult cardiac arrests to airway management with ETI or LT.
We found that compared with traditional ETI, LT was associated with almost 3% better survival. Out-of-hospital cardiac arrest survival in the US is less than 10%, so the observed difference is important. Continue reading
