Targeted temperature management (TTM) previously known as therapeutic hypothermia or protective hypothermia is an active treatment that tries to achieve and maintain a specific body temperature in a person for a specific duration of time in an effort to improve health outcomes during recovery after a period of stopped blood flow to the brain. [1]
Rewarming is typically continued until a person's temperature is greater than 32 °C (90 °F). [2] If there is no improvement at this point or the blood potassium level is greater than 12 millimoles per litre at any time, resuscitation may be discontinued. [2] Hypothermia is the cause of at least 1,500 deaths a year in the United States. [2]
Afterdrop is a continued cooling of core temperature during the initial stages of rewarming from hypothermia.. Afterdrop is attributed to the return of cold blood from extremities to the core due to peripheral vasodilatation, thus causing a further decrease of deep body temperature. [1]
A study conducted in 2002-2004 showed that treatment with therapeutic hypothermia for patients resuscitated after cardiac arrest due to ventricular fibrillation led to a positive outcome (Glasgow-Pittsburgh Cerebral Performance category 1 or 2) in 24 of 43 patients compared to only 11 of 43 patients in the standard resuscitation group where no ...
Choice of rewarming method depends on the suspected extent of skin injury and severity of hypothermia (if present). [11] Passive rewarming techniques such as blankets may be sufficient for milder injuries. [11] Active rewarming techniques such as warm intravenous fluids or warm water baths may be needed for more severe injuries.
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. Profound hypothermia (< 14 °C) usually isn't used clinically. It is a subject of research in animals and human clinical trials.
She retires Sunday after 31 years at STRS, one of the nation’s oldest and largest public pension funds. Its more than 500,000 members include active and inactive public school teachers and retirees.
The Bair Hugger system uses convective warming, also known as forced-air warming, to prevent and treat perioperative hypothermia. The system includes two primary components: a warming unit and a disposable blanket. The warming unit is connected by a flexible hose to the single-use blanket.
