What are the risks of TTM?

Risks of Targeted Temperature Management (TTM) include cardiovascular issues (arrhythmias, low heart rate), metabolic disturbances (high blood sugar, electrolyte shifts like low potassium/magnesium), bleeding (coagulopathy), infections (like pneumonia, due to immune changes), kidney problems (cold diuresis), shivering (increasing oxygen demand), decreased gut motility, and complications during rewarming (electrolyte imbalance, hemodynamic instability). These risks, however, are weighed against TTM's significant benefit in improving neurological outcomes after cardiac arrest, say em-med.com and em-med.com.

What are the risks of targeted temperature management?

Does TTM actually work?

Although laboratory science has repeatedly shown a clear survival benefit following cardiac arrest when TTM is used (and indeed, with a strong dose–effect relationship), similar results have been elusive in clinical trials, with some trials showing benefit and others showing no clinical effect when TTM is employed (Fig ...

What are the risks of therapeutic hypothermia?

Some of these risks include: Another abnormal heart rhythm, especially slow heart rates. Severe blood infection (sepsis) Blood is less able to clot.

How long does TTM treatment last?

According to the European Resuscitation Council (ERC), targeted temperature management (TTM) is a standard therapeutic approach for patients who have survived cardiac arrest[1]. The recommended duration of this therapy is 24 hours, during which the patient's core body temperature should be maintained between 32–36°C.

Targeted Temperature Management (TTM) - Therapeutic Hypothermia - Hypothermia Protocol

What triggers trichotillomania?

Trichotillomania (hair pulling disorder) has no single cause but stems from a complex mix of genetics, brain chemistry, and environmental factors, often triggered or worsened by stress, anxiety, and boredom, acting as a coping mechanism for tension relief, and frequently co-occurs with conditions like OCD and depression. It involves a disruption in brain pathways related to habit formation and impulse control, with potential imbalances in neurotransmitters like serotonin and dopamine.
 

Who is a candidate for TTM?

Any survivor of cardiac arrest who is comatose (defined as unarousable unresponsiveness to external stimuli) should be considered as a candidate for TTM regardless of the initial presenting rhythm, and the decision to opt for targeted hypothermia versus targeted normothermia should be made on a case-by-case basis.

What is the success rate of therapeutic hypothermia?

Therapeutic hypothermia group. There were 128 patients treated with hypothermia. Eighty-two (64%) survived and 88% of survivors achieved a favorable functional outcome (CPC score ≤2) at hospital discharge.

What are the 7 danger signs in a newborn baby?

The 7 key danger signs in a newborn, often emphasized by health organizations like the WHO, are difficulty breathing, poor feeding, fever or very cold skin, reduced activity/lethargy, fits/convulsions, severe jaundice, and no/few stools or urine. These signs signal a potentially serious illness and require urgent medical attention, as newborns can deteriorate rapidly, needing immediate assessment and care to prevent severe complications. 

What organ shuts down first with hypothermia?

When hypothermia happens, blood is shunted away from the extremities in an attempt to keep the organs warm. If the body temperature continues to fall, organs such as the liver and kidneys begin to shut down as the blood is redirected to protect the heart and brain.

What should be avoided in TTM?

Avoid fever following targeted temperature management (TTM), as any elevated temperature is associated with worse neurologic outcome. Avoid hypoxia, with administration of oxygen saturation above 94%. However, hyperoxia is also harmful.

What happens if you fall asleep with hypothermia?

Drowsiness, which may be overlooked, is really quite dangerous if it is from hypothermia. In fact, people can become drowsy and fall asleep, but they may not wake up, especially if this happens outside in the cold. People who freeze to death really die first from hypothermia.

At what temperature does shivering stop?

Stage 3 - If your body temperature drops below 32ºC (89.6ºF), the shivering will stop but you'll have trouble speaking, thinking, and walking. You may even develop amnesia.

How long should you do TTM?

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.

What are the risks of targeted therapy?

What are common side effects of targeted therapy?

• Skin, hair, and nail changes. Many targeted therapies cause skin, hair, and nail changes (including hair loss). ...
• Allergic or infusion reactions. ...
• High blood pressure. ...
• Bleeding or blood clotting problems. ...
• Slow wound healing. ...
• Heart damage. ...
• Autoimmune reactions. ...
• Swelling.

What medical conditions use TTM?

TTM is effective in five primary categories of medical events:

• Neonatal encephalopathy.
• Cardiac arrest.
• Ischemic stroke.
• Traumatic brain or spinal cord injury without a fever.
• Neurogenic fever following brain trauma.

What is the 5 5 5 rule for newborns?

The "newborn 5-5-5 rule" is a postpartum guideline for the first 15 days of recovery after childbirth, focusing on rest and bonding: 5 days in bed (minimal movement), 5 days on the bed (sitting up, light activity around the bed), and 5 days around the bed/home (gradually increasing activity within the home). It's rooted in traditional practices (like Asian "Golden Month") to encourage new mothers to prioritize healing, bond with the baby, and accept help to avoid mental and physical strain.
 

What makes a newborn high risk?

What are high-risk infants? Doctors refer to babies who are born prematurely or who are sick when they are born as high-risk infants. This means they have a high risk of short and long-term health and developmental challenges.

Which weeks are hardest with a newborn?

The hardest weeks with a newborn are generally considered the first 6 to 8 weeks, with peak fussiness often around week 6, due to extreme sleep deprivation, learning to interpret baby's cues, postpartum recovery for the birthing parent, and the baby's immature systems leading to intense crying (the "witching hour"). Parents struggle with constant feeding, disrupted sleep, physical recovery, and the overwhelming adjustment to life with a demanding new baby, making this period feel relentless and exhausting. 

What is the recommended range of TTM?

(1,2). 1. Target temperature of 33 C (range 32-34 C) is recommended, and should be achieved within 4 hours of obtaining return of spontaneous circulation (ROSC), and maintained for at least 24 hours from time the target temperature is achieved.

Which newborn is most at risk for hypothermia?

Infants of lower gestational age and birth weight and those born to Black and Asian mothers carried the highest odds of hypothermia.

How does TTM work?

Targeted Temperature Management (TTM) is a controlled therapy in which the patient's body temperature is lowered in order to preserve brain function after a cardiac arrest.

What is TTM in ICU?

Abstract Background Targeted temperature management (TTM) is often used in neurocritical care to minimize secondary neurologic injury and improve outcomes.

What is the alternative to therapeutic hypothermia?

Promising neuroprotective agents include antiepileptic drugs, erythropoietin, melatonin and xenon.

What is a TTM procedure?

Targeted temperature management is used during open-heart surgery because it decreases the metabolic needs of the brain, heart, and other organs, reducing the risk of damage to them. The patient is given medication to prevent shivering. The body is then cooled to 25–32 °C (77–90 °F).
