|October 1, 2011
Summary
Preventing perioperative hypothermia is crucial for surgical patients. Prewarming patients for at least 30 minutes may significantly reduce the risk of developing hypothermia and its associated complications.
Area of Science:
- Anesthesiology
- Surgical Patient Care
Background:
- Perioperative hypothermia (core body temperature <36°C) is common in unwarmed surgical patients.
- Mild hypothermia increases morbidity and mortality, notably a threefold rise in surgical site infections in colorectal surgery.
- Guidelines exist to reduce hypothermia incidence as part of the Surgical Care Improvement Project.
Purpose of the Study:
- To review temperature regulation physiology, hypothermia mechanisms, and anesthetic effects.
- To summarize consequences of hypothermia and current recommendations for perioperative normothermia.
Main Methods:
- Literature review of thermoregulation.
- Analysis of hypothermia effects and anesthetic impacts.
- Synthesis of current guidelines for normothermia maintenance.
Main Results:
- Prewarming patients for a minimum of 30 minutes shows potential in reducing subsequent hypothermia risk.
Conclusions:
- Continuous body temperature monitoring is essential.
- Active and passive warming measures are key to preventing unintended perioperative hypothermia.
- Preventing hypothermia complications is critical for patient outcomes.

01:29Decreased 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...

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

01:19Homeostatic 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...
01:25Increased 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.
01:24Parenteral Anesthetics: Overview
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
01:22Methods 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.
