People in cardiac arrest who are resuscitated by first responders using a laryngeal breathing tube instead of a traditional breathing tube are more likely to survive, according to a study from the University of Texas Health Science Center at Houston published in JAMA.
More than 400,000 people are treated each year in the United States for out-of-hospital cardiac arrest, usually caused by a heart attack, and only about 10 percent survive. Delivery of oxygen to the lungs, called intubation, is a critical part of reviving a person from cardiac arrest.
This study, funded by the National Heart, Lung, and Blood Institute of the NIH and called the Pragmatic Airway Resuscitation Trial, is the largest to date testing oxygen delivery methods used by firefighters, EMTs, and paramedics. It compared survival rates in 3,000 adults with out-of-hospital cardiac arrest, half treated with a laryngeal breathing tube airway and half having traditional endotracheal intubation.
According to the researchers, 18.3 percent of those treated with the laryngeal tube survived three days in the hospital and 10.8 percent survived to leave the hospital. Of those treated with the traditional breathing tube, 15.4 percent survived three days and 8.1 percent survived to leave the hospital.
