NEW YORK, NY-- Rescuers who perform chest compressions at the same time that another uses a defibrillator may be at risk of electric shock, a new study suggests.
In a trial with cadavers, so-called hands-on defibrillation exposed rescuers to 200 to 827 volts, or 1 to 8 joules, which is more than safety standards recommend.
"The rescuer energy we measured (1 to 8 J) is not dramatically high, but it shares a waveform and frequency designed to affect cardiac myocytes. In susceptible rescuers, this could result in serious injury," Dr. Daniel Lemkin, an emergency medical physician at the University of Maryland School of Medicine in Baltimore, Maryland, who led the study, told Reuters Health by email.
Instead, Dr. Lemkin and his colleagues advise rescuers to perform compressions while the defibrillator charges, remove their hands during defibrillation, and then resume immediately afterward.
The sudden death of an athlete on the playing field remains one of the most striking and tragic events in sport. For the sports physician, the occurrence of an athlete in sudden cardiac arrest is both unforgettable and terrifying. Well-known cases such as Hank Gathers (1990), Marc-Vivien Foé (2003) and Fabrice Muamba (2012), provide graphic examples of an athlete enduring this deadly crisis—collapsed and unresponsive, eyes rolled back, brief myoclonic seizure-like activity and perhaps the presence of agonal respirations as limbs go from rigid to limp. For physicians responsible for the medical care of athletes, a single universal priority should guide our clinical efforts, namely to protect the health and safety of athletes. This journal once again assumes a leading role in the field of sports cardiology by presenting current information relevant to the prevention of sudden cardiac death (SCD) in athletes.
PITTSBURGH, PA--The Sudden Cardiac Arrest Foundation and Enerspect Medical Solutions have joined forces to enable individuals and organizations to donate $450 to the Foundation, a 501(c)(3) nonprofit organization, and receive a free, recertified automated external defibrillator (AED). They may also opt to receive a new AED by contributing $1,200.
PITTSBURGH, PA--The Sudden Cardiac Arrest Foundation presented a well-attended session, “Addressing the Needs of Survivors and Loved Ones,” during the Emergency Cardiovascular Care Update earlier this month in Las Vegas. Speakers included Mary Newman, Foundation president, Susan Koeppen, a TV news anchor and survivor, Kelly Sawyer, MD, an emergency physician and survivor, and Jennifer Chap, a marketing professional who saved her husband’s life with CPR.
PITTSBURGH, PA--University of Pittsburgh researchers have received $1.8 million from the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, to create a unique database of electrocardiogram (ECG) information that could one day be used to better guide real-time decision making during cardiopulmonary resuscitation (CPR) for cardiac arrest. The database would be the largest repository of its kind and could lead to new ways to evaluate CPR and patient outcomes.
LAS VEGAS, NV--The 2014 Emergency Cardiovascular Care Update (ECCU), a biennial conference of the Citizen CPR Foundation held earlier this month in Las Vegas, celebrated survival from sudden cardiac arrest. Each plenary session was introduced by a survivor, and the conference featured an educational track targeted to survivors and rescuers, including a session, “Addressing the Needs of Survivors and Loved Ones,” presented by the Sudden Cardiac Arrest Foundation.
PITTSBURGH, PA--TV news anchor, Susan Koeppen, who serves as National Spokesperson for the Sudden Cardiac Arrest Foundation, shared her dramatic and inspirational story as keynote speaker at the Emergency Cardiovascular Care Update earlier this month in Las Vegas. “I’ve worked in television for two decades and we have a phrase in TV, ‘Dip to black,’” she began. “You dip to black in a story to create drama, evoke emotion, grab attention. On November 20, 2011, my world dipped to black when I suffered sudden cardiac arrest.”
LAS VEGAS, NV--The Sudden Cardiac Arrest Foundation and the Citizen CPR Foundation announced the winners of the ECCU 2014 "Video Minute” Contest during the Emergency Cardiovascular Care Update, June 6 in Las Vegas. The purpose of the contest is to increase awareness about sudden cardiac arrest, the importance of bystander CPR and automated external defibrillators, and/or recognition of a heart attack.
Sudden cardiac death (SCD) is the leading medical cause of death in athletes; however, the precise incidence is unknown. The objectives of this review were to examine studies on the rate of SCD in athletes, assess the methodological strengths and weaknesses used to arrive at estimates, compare studies in athletes with estimates in similar populations and arrive at an approximation of the incidence of SCD based on the best available evidence.
A comprehensive literature search was performed in PubMed using key terms related to SCD in athletes. Articles were reviewed for relevance and included if they contained information on the incidence of SCD in athletes or young persons up to the age of 40. The reference list from each manuscript was reviewed for additional relevant articles. The methods for case identification were examined, as well as the inclusion and exclusion criteria and the precision of the population denominator studied.
