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.
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:
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...
Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's forehead...
Assessing Body Temperature - Axilla01:14

Assessing Body Temperature - Axilla

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Summary

Postoperative fever is common after total knee arthroplasty (TKA), but uncomplicated TKA patients typically show mild temperature increases. Lower hemoglobin loss may correlate with higher fever, while prolonged fever suggests potential infection.

Area of Science:

  • Orthopedic Surgery
  • Postoperative Care
  • Clinical Thermoregulation

Background:

  • Fever is a frequent occurrence following total knee arthroplasty (TKA).
  • The typical pattern of temperature elevation and its relationship with perioperative variables after TKA are not well-defined.
  • Understanding these trends is crucial for distinguishing normal responses from complications.

Purpose of the Study:

  • To characterize the postoperative body temperature trend in patients undergoing TKA.
  • To identify factors influencing body temperature changes after TKA.
  • To compare temperature patterns between uncomplicated TKA and prosthetic joint infections.

Main Methods:

  • Retrospective chart review of 186 clinically uncomplicated TKA patients.
  • Recording body temperature changes during the first 5 postoperative days.
  • Analysis of temperature trends in patients with acute prosthetic infection for comparative purposes.

Main Results:

  • Uncomplicated TKA patients exhibited an average peak temperature of 37.9°C (3.3% increase from baseline).
  • Temperature elevation was most pronounced on postoperative days 1 and 2; only 4 patients reached 39°C.
  • Lower hemoglobin loss was associated with higher peak temperatures.
  • Patients with prosthetic infection showed prolonged fever and delayed peak temperature presentation.

Conclusions:

  • A distinct pattern of elevated body temperature exists after uncomplicated TKA.
  • Hemoglobin loss appears to be a significant factor influencing postoperative temperature.
  • Fever exceeding 39°C, prolonged fever, or delayed peak temperature warrants clinical suspicion for infection or other complications.
