Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

1.6K
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...

Temperature Measurement Sites

4.2K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Equipments Used to Measure Body Temperature

2.0K
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

Summary

Temporal artery biopsy length is crucial for diagnosing giant cell arteritis. Many biopsies at our hospital fall short of the recommended 1 cm minimum, potentially impacting diagnostic accuracy.

Area of Science:

  • Rheumatology
  • Pathology
  • Surgical Pathology

Background:

  • Giant cell arteritis (GCA) diagnosis relies heavily on temporal artery biopsy (TAB).
  • International guidelines recommend TAB specimens be at least 1 cm, ideally >2 cm, to maximize diagnostic yield.
  • Biopsy length directly correlates with the probability of detecting GCA.

Purpose of the Study:

  • To audit the adequacy of temporal artery biopsy specimen lengths obtained at University Hospital Ayr.
  • To assess compliance with established guidelines for TAB specimen size.
  • To evaluate the impact of specimen length on the detection rate of giant cell arteritis.

Main Methods:

  • Retrospective review of histopathology reports for all temporal artery biopsies.
  • Data collection period: January 2011 to June 2013.
  • Analysis of specimen lengths and correlation with diagnostic findings.

Main Results:

  • Fifty-six TAB specimens were analyzed, with lengths ranging from 0.5 cm to 3.1 cm (mean 1.4 cm).
  • Only 66% of biopsies met the minimum 1 cm length requirement; 34% were inadequate.
  • Of the seven positive GCA cases, 86% measured ≥1 cm, highlighting the importance of adequate length.

Conclusions:

  • Compliance with recommended temporal artery biopsy length guidelines is suboptimal at the audited center.
  • Inadequate specimen length ( <1 cm) is associated with a missed diagnosis of GCA.
  • Implementing changes to ensure adequate biopsy length is critical for improving diagnostic accuracy in GCA.
