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.

Factors Affecting Body Temperature

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may include:

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...

Acute Kidney Injury VI: Nursing Management

Acute Kidney Injury VI: Nursing Management

Acute Kidney Injury (AKI) results in an inability to maintain fluid, electrolyte, and acid-base balance. Effective nursing management is critical in improving patient outcomes and includes comprehensive patient assessment and targeted interventions.Comprehensive Patient AssessmentA detailed history collection is essential, focusing on any recent infections, nephrotoxic medication use, or chronic conditions such as hypertension and diabetes that may contribute to AKI. During the physical...

Summary

Therapeutic hypothermia (TH) improves brain oxygen supply and reduces intracranial pressure. This neuroprotective method, though underutilized, is vital for acute care practitioners.

Area of Science:

Critical Care Medicine
Neurology
Cardiology

Background:

Therapeutic hypothermia (TH) has a long history in medicine, with increasing use in emergency departments, ICUs, and operating rooms.
Its application is based on mechanisms like improved oxygen supply to ischemic brain areas and reduced intracranial pressure.

Observation:

Mild-to-moderate TH (33°C ± 1°C) post-cardiac arrest resuscitation offers neuroprotection.
TH affects the cardiovascular system by decreasing heart rate and increasing systemic vascular resistance.
Cardiac output reduces by 7% per 1°C core temperature drop, while stroke volume and mean arterial pressure are maintained.

Findings:

TH demonstrates neuroprotective effects and influences cardiovascular parameters.
Despite evidence, this life-saving intervention remains underutilized globally.

Implications:

Acute care practitioners should consider the expanded clinical applications of therapeutic hypothermia.
Further integration of TH protocols can improve patient outcomes in critical care settings.
