Summary
Deliberate mild hypothermia shows promise for brain injury and cardiac arrest recovery. However, clinical evidence for stroke, brain trauma, and neonatal asphyxia remains limited, with ongoing research into its effects on intracranial pressure.
Area of Science:
- Neuroscience
- Critical Care Medicine
- Therapeutic Hypothermia
Background:
- Extensive experimental data supports mild hypothermia (33-35°C) for injured brain and post-cardiac arrest neurological outcomes.
- Clinical evidence for hypothermia's benefit in stroke, brain trauma, and neonatal asphyxia is currently lacking or controversial.
- Hypothermia is known to reduce elevated intracranial pressure, potentially via hypothermia-induced hypocapnia.
Purpose of the Study:
- To review the current clinical evidence for therapeutic hypothermia in neurological conditions.
- To explore the mechanisms and optimal parameters for hypothermia in managing elevated intracranial pressure.
Main Methods:
- Literature review of experimental and clinical studies on therapeutic hypothermia.
- Analysis of data regarding temperature targets, duration, and rewarming protocols.
Main Results:
- No additional benefit of hypothermia was observed below 34°C.
- A minimum duration of 48 hours of hypothermia may be required for managing elevated intracranial pressure.
- Slow rewarming is crucial to prevent adverse effects.
Conclusions:
- While promising for certain conditions, the clinical efficacy of hypothermia in stroke, brain trauma, and neonatal asphyxia requires further investigation.
- Optimal temperature, duration, and rewarming strategies for therapeutic hypothermia need continued research to maximize patient benefit and minimize risks.

01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
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.
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
