Summary
Hypoxic-ischemic encephalopathy (HIE) is a severe birth injury. Therapeutic hypothermia, or cooling, initiated early, significantly improves outcomes for affected newborns by reducing death and disability.
Area of Science:
- Neonatal neurology
- Perinatal medicine
- Neurocritical care
Context:
- Hypoxic-ischemic encephalopathy (HIE) affects 2-3/1000 live births, often resulting in poor outcomes despite supportive care.
- Delayed neuronal loss occurs due to a complex biochemical cascade post-hypoxia-ischemia.
- Current interventions have yielded disappointing results in improving HIE outcomes.
Purpose:
- To review the pathophysiology of HIE and the neuroprotective effects of therapeutic hypothermia.
- To highlight the critical timing and duration of cooling for optimal neuroprotection.
- To emphasize the need for standardized guidelines and data collection for HIE management.
Summary:
- HIE involves delayed neuronal injury with distinct phases, including a latent period followed by secondary deterioration.
- Moderate therapeutic hypothermia, initiated early, demonstrates significant neuroprotection.
- Clinical trials confirm that post-resuscitation cooling is safe and reduces death or disability at 18 months.
Impact:
- Therapeutic hypothermia is now a recommended standard of care for neonatal HIE.
- Improved neuroprotection can lead to better long-term developmental outcomes for affected infants.
- Development of national guidelines and registries is crucial for consistent HIE care and research.

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:22Methods of reducing fever
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:25Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
