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...

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...

Types of Fever

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.
Here are the different types of fever:

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...

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.

Anesthesiology
Pharmacology
Medical Case Reports

Background:

Malignant hyperthermia syndrome is a rare, life-threatening pharmacogenetic disorder of skeletal muscle.
It is typically triggered by volatile anesthetics and succinylcholine.

Observation:

A 57-year-old male developed MH symptoms (hyperthermia, tachycardia, acidosis) during general anesthesia for cerebral catheterization.
Symptoms included rising end-tidal CO2, elevated temperature, tachycardia, decreased oxygen saturation, and diaphoresis.

Findings:

The patient was diagnosed with malignant hyperthermia and the procedure was halted.
Treatment involved disconnecting from the anesthesia machine, ventilation with 100% oxygen, active cooling, and pharmacologic support.

Implications:

This case highlights the importance of prompt recognition and management of malignant hyperthermia during anesthesia.
Successful treatment underscores the efficacy of current therapeutic strategies for MH crises.
