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...
Factors Affecting Body Temperature01:28

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:
Parenteral Anesthetics: Overview01:24

Parenteral 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.
General Anesthesia: Overview01:24

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...
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.

Peripheral Artery Disease V: Postoperative Nursing Management

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...

Area of Science:

  • Anesthesiology
  • Nursing
  • Surgical Care

Background:

  • Inadvertent hypothermia (core body temperature < 36°C) is a common complication during surgery and anesthesia.
  • Despite documented risks, maintaining normothermia in surgical patients presents ongoing challenges for healthcare providers.
  • Effective management of perioperative temperature requires a collaborative, team-based approach.

Purpose of the Study:

  • To review the physiological basis of intraoperative temperature changes.
  • To identify key risk factors contributing to unintentional perioperative hypothermia.
  • To outline evidence-based strategies for preventing and managing hypothermia in surgical patients.

Main Methods:

  • Literature review on perioperative thermoregulation.
  • Analysis of physiological factors influencing body temperature during surgery.
  • Synthesis of clinical guidelines and best practices for hypothermia management.

Main Results:

  • Understanding the physiology of temperature fluctuation is crucial.
  • Several patient and procedural factors increase hypothermia risk.
  • Proactive warming measures and timely interventions are essential.

Conclusions:

  • Evidence-based practices are critical for preventing and managing perioperative hypothermia.
  • Nurses play a vital role in maintaining thermal balance throughout the perioperative period.
  • A multidisciplinary effort is necessary to ensure patient safety and optimal outcomes.
