Methods of reducing fever01:22

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 Temperature01:25

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.
Types of Fever01:25

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:
Patterns of Fever01:26

Patterns of Fever

Before understanding the types and patterns of fever, it is essential to know its phases.
Decreased Body Temperature01:29

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...
Endocarditis IV: Nursing Management01:29

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Summary
This summary is machine-generated.

Fever after subarachnoid hemorrhage (SAH) is linked to worse outcomes and higher mortality. While cooling methods can reduce fever, they may cause shivering, potentially offsetting benefits.

Area of Science:

  • Neurology
  • Critical Care Medicine
  • Neurocritical Care

Background:

  • Fever is a common complication in patients following subarachnoid hemorrhage (SAH).
  • The impact of fever on patient outcomes and mortality in SAH requires thorough investigation.
  • Effective temperature control strategies are crucial for managing SAH patients.

Purpose of the Study:

  • To synthesize current literature on fever incidence, impact, and treatment in subarachnoid hemorrhage.
  • To evaluate the relationship between fever and patient outcomes, including mortality.
  • To assess the efficacy and potential drawbacks of various fever management strategies.

Main Methods:

  • Conducted an electronic literature search up to August 2010.
  • Identified and analyzed 24 original research studies focusing on fever in SAH.
  • Included studies examining fever's effect on outcomes, temperature control, and shivering.

Main Results:

  • Fever during acute hospitalization for SAH is consistently associated with poorer outcomes.
  • Increased mortality rates are linked to the presence of fever in SAH patients.
  • Antipyretics, surface cooling, and intravascular cooling can reduce fever, but shivering may counteract benefits.

Conclusions:

  • Fever is a significant negative prognostic factor in subarachnoid hemorrhage.
  • Temperature management in SAH patients is complex, with potential benefits and risks associated with cooling methods.
  • Further research is needed to optimize fever control strategies to improve SAH patient outcomes.
