Summary
Post-anesthetic shivering is usually normal body temperature regulation. Maintaining normal body temperature during surgery and treating postoperative pain can prevent or reduce shivering.
Area of Science:
- Anesthesiology
- Physiology
- Postoperative Care
Background:
- Post-anesthetic shivering is a common complication.
- Shivering can be thermoregulatory or non-thermoregulatory.
- Understanding the cause is crucial for effective management.
Purpose of the Study:
- To differentiate between types of post-anesthetic shivering.
- To identify effective strategies for preventing and treating shivering.
- To explore the role of core hypothermia, cytokines, and postoperative pain.
Main Methods:
- Review of existing literature on post-anesthetic shivering.
- Analysis of thermoregulatory responses during and after anesthesia.
- Evaluation of the impact of intraoperative normothermia, cytokine release, and pain management.
Main Results:
- Most shivering is thermoregulatory, linked to core hypothermia.
- Maintaining intraoperative normothermia effectively prevents shivering.
- Non-thermoregulatory shivering in normothermic patients may stem from postoperative pain or other causes.
- Antipyretic drugs can reduce shivering post-cardiopulmonary bypass.
Conclusions:
- Thermoregulatory shivering is primarily managed by maintaining normothermia.
- Non-thermoregulatory shivering may be alleviated by effective postoperative pain management.
- Further research into non-thermoregulatory causes and treatments is warranted.

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...
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.

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
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.
01:28Factors 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.

01:26Thermoregulation
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...
