What is an optimal temperature during therapeutic hypothermia?
In most centers, the patient is actively cooled by using an induced hypothermia protocol for 24 hours to a goal temperature of 32ºC-36ºC. The goal is to achieve the target temperature as quickly as possible. In most cases, this can be achieved within 3-4 hours of initiating cooling.
How do you monitor temperature during therapeutic hypothermia?
Patient Monitoring and Management: Monitor and document vital signs every 15 minutes X4, every 30 minutes X2, then every 1 hour with the exception of patient temperature, which will continue every 15 minutes until reaching target temperature of 33°C.
What are the indications for therapeutic hypothermia?
Therapeutic Hypothermia (TH) shall be initiated on all adult cardiac arrest patients with return of spontaneous circulation (ROSC) that fit the inclusion criteria, and does not have any of the following: eye opening to painful stimuli, pre-existing coma, traumatic arrest (either penetrating or blunt), body temperature …
How is TTM done?
TTM should be induced and maintained at the selected target temperature for 24 hours, and rewarmed gradually at a rate not faster than 0.5°C per hour. Every hour of delay in TTM after ROSC increases mortality by 20%. Thus, TTM should be initiated as soon as possible after ROSC.
When should you not do targeted temperature management?
A temperature below 30 °C (86 °F) should be avoided, as adverse events increase significantly. The person should be kept at the goal temperature plus or minus half a degree Celsius for 24 hours. Rewarming should be done slowly with suggested speeds of 0.1 to 0.5 °C (0.18 to 0.90 °F) per hour.
How long is therapeutic hypothermia?
The therapeutic hypothermia will likely last around 24 hours. The medical team will slowly rewarm you over several hours. They may set cooling blankets at gradually higher temperatures. In some cases, they may use rewarming devices as well.
Why do doctors lower a patient’s body temperature?
The chemical reactions of the body slow down. The lowered temperature may also lessen inflammation in the brain. Both of these factors may help reduce injury.
What temperature do scientists bring bodies down to for hypothermia treatment and how much better are your chances of survival?
Therapeutic hypothermia — cooling the body and brain down to 33°C — is the method used worldwide to treat cardiac arrest, even though a lower body temperature may raise the risk of side-effects. However, keeping the temperature steady at 36°C is just as effective, a study led by Lund University researchers has found.
How effective is therapeutic hypothermia?
Compared with untreated patients, those treated with therapeutic hypothermia had significantly lower rates of in-hospital survival (29.2% vs 27.4%, respectively), as well as lower rates of survival to discharge with favorable neurological status.
How long is targeted temperature management?
We suggest that if targeted temperature management is used, duration should be at least 24 hours, as in the 2 largest previous RCTs (weak recommendation, very low-quality evidence).
How long does it take to warm up after therapeutic hypothermia?
