The 2013 ILCOR and 2010 American Heart Association guidelines support the use of cooling following resuscitation from cardiac arrest. [1] [7] These recommendations were largely based on two trials from 2002 which showed improved survival and brain function when cooled to 32–34 °C (90–93 °F) after cardiac arrest.
In the 1980s, the use of hypothermia on dogs after cardiac arrest demonstrated positive outcomes, including neurological status and survival. In 2005, the American Heart Association implemented recommendations and guidelines for mild hypothermia in post-resuscitation support after cardiac arrest with return of spontaneous circulation. [2]
Consequently, safe circulatory arrest times for mild and moderate hypothermia are only 10 and 20 minutes respectively. [32] While moderate hypothermia may be satisfactory for short surgeries, deep hypothermia (20 °C to 25 °C) affords protection for times of 30 to 40 minutes at the bottom of this temperature range.
Current international guidelines suggest cooling adults after cardiac arrest using targeted temperature management (TTM) with the goal of improving neurological outcomes. [123] The process involves cooling for a 24-hour period, with a target temperature of 32–36 °C (90–97 °F), followed by gradual rewarming over the next 12 to 24 hrs.
He has also worked on evaluation of CPR and resuscitation performance, testing of new teaching methods of CPR, assessment of neurologic outcomes after cardiac arrest and methods to improve the application of therapeutic hypothermia. He developed a training course for post-arrest care and targeted temperature management, known as the Penn TTM ...
Afterdrop, cardiac arrest: Duration: Until the body temperature is raised to near-normal levels: Types: Primary hypothermia: caused by exposure to a cold environment; Secondary hypothermia: caused by an underlying pathology that prevents the body from generating enough core heat. Causes: Mainly exposure to cold weather and cold water immersion ...
EPR uses hypothermia, drugs, and fluids to "buy time" for resuscitative surgery. If successful, EPR may someday be deployed in the field so that paramedics can suspend and preserve patients for transport. EPR is similar to deep hypothermic circulatory arrest (DHCA) in that hypothermia is induced. However, the purposes and procedures of EPR ...
The causal pathology of the cardiac arrest is thought to be reversible with an available medical or surgical intervention. The ECPR guidelines produced by Alfred Health provides a more detailed series of indications which considers the specific indications for both out-of-hospital cardiac arrest (OOHCA) and in-hospital cardiac arrest (IHCA ...
