Hypothermia

Hypothermia is the intentional cooling of a patient’s body temperature to reduce brain and organ damage. The goal of hypothermia is to preserve brain and organ function by decreasing the body’s metabolic rate and reducing the amount of oxygen needed by these organs. Hypothermia is used in a variety of medical scenarios, including cardiac arrest, stroke, near drowning, head injury, and cardiac surgery. When a patient’s body is cooled to a temperature below 35°C (95°F), the body’s metabolism slows. This slow-down in metabolic activity reduces the amount of oxygen needed for cells to function. The decrease in oxygen to the brain and other organs helps to minimize the damage caused by decreased blood flow and oxygen deprivation. Hypothermia also helps reduce inflammation, which can be caused by a traumatic event such as a stroke or cardiac arrest. Inflammation can lead to further damage to the body’s organs, so reducing it may help reduce the damage caused by the initial event. Hypothermia can be induced in several ways. One method is using cooling blankets or pads placed on the patient’s body. Another method is to use a catheter to deliver cold saline directly to the patient’s major vessels. The third method is to use an extracorporeal membrane oxygenation (ECMO) machine, which circulates cold blood through the patient’s body. Hypothermia has been shown to reduce mortality and morbidity in patients who have suffered a traumatic event. However, it is important to ensure that the patient is monitored closely during and after the procedure to ensure that their body temperature is maintained at the appropriate level.
