Decreased Body Temperature

Decreased 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...

Methods of reducing fever

Methods 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.
Pharmacological Methods of Reducing Fever:

Increased Body Temperature

Increased 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.

Homeostatic Imbalances in Body Temperature

Homeostatic Imbalances in Body Temperature

Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Summary

Therapeutic hypothermia (TH) improves survival rates for sudden cardiac arrest (SCA) survivors. This intervention, though recommended, remains underutilized despite its proven benefits in preventing neurological damage.

Area of Science:

Cardiology
Neurology
Critical Care Medicine

Background:

Sudden cardiac arrest (SCA) affects 300,000 individuals annually, with survival rates ranging from 10% to 25%.
Post-resuscitation syndrome, including brain injury, often leads to permanent neurological deficits in SCA survivors.

Observation:

Landmark studies demonstrate that therapeutic hypothermia (TH) significantly enhances hospital discharge rates for SCA survivors.
Despite endorsements from major medical organizations, TH is not widely recognized or implemented.

Findings:

Therapeutic hypothermia effectively mitigates post-cardiac arrest brain injury.
TH improves neurological outcomes and survival rates following SCA and resuscitation.

Implications:

Perianesthesia nurses require specialized knowledge to manage TH effectively and address potential side effects.
Increased awareness and implementation of TH are crucial for improving patient outcomes after SCA.
