Hypothermia

Introduction Hypothermia is the consequence of abnormal hypothermia. Can lead to the acceleration of all physiological functions, including cardiovascular and respiratory systems, nerve conduction, mental acuity, neuromuscular reaction time and metabolic rate. In young children, soaking the whole body in the water close to icing is too low to protect the brain during hypoxia. Hypothermia is most common in the cold season or in water, but it can occur in summer or warm seasons if metabolic or active heat (trembling) does not maintain core body temperature. Hypothermia can also occur after severe trauma. Immobility, wearing wet clothes, cold winds and lying on cold surfaces can increase the risk of hypothermia.

Cause

Due to long-term exposure to any temperature, when the body dissipates heat more than heat, it can cause hypothermia. Hypothermia is most common in the cold season or in water, but it can occur in summer or warm seasons if metabolic or active heat (trembling) does not maintain core body temperature. Hypothermia can also occur after severe trauma. Immobility, wearing wet clothes, cold winds and lying on cold surfaces can increase the risk of hypothermia.

Signs and symptoms of hypothermia: unable to self-control trembling, unclear articulation, abnormal behavior, fatigue, drowsiness. The coordination between the hands and the body is worse, and the breathing and pulse are weakened. Hypothermia can lead to acceleration of all physiological functions, including cardiovascular and respiratory systems, nerve conduction, mental acuity, neuromuscular reaction time and metabolic rate. In young children, soaking the whole body in the water close to icing is too low to protect the brain during hypoxia.

Differential diagnosis

Thermoregulation of body temperature: Central fever refers to fever caused by abnormalities in the body temperature regulation caused by central nervous system diseases. Central fever is rare in various causes of fever, and its performance and treatment are also different from common fevers caused by various infectious and other causes. Therefore, in the clinical determination of central fever, first of all, except for infectious, drug-induced and other causes of fever. For moderately unacceptable increases in moderate body temperature, it cannot be easily considered as central fever.

Neonatal hypothermia: The neonatal skin temperature is maintained at 36-37 ° C, the lowest oxygen consumption, and can ensure normal metabolism. The so-called hypothermia refers to the core (rectal) body temperature 35 ° C, the body temperature is too low, the body surface is cold, the reaction is low. The mechanism of hypothermia is the reduction of heat production or heat dissipation, or both. Therefore, in neonatal diseases, any decrease in heat production or increased heat dissipation can be seen as a main symptom due to hypothermia. Hypothermia can not only cause hard swelling of the skin, but also damage the vital organs of the body, affect function, and even lead to death.
