Cerebral temperature and epidural pressure during whole body hyperthermia in dogs
Abstract:
Whole body hyperthermia was performed on 13 anaesthetized and intubated dogs. Cerebral temperature and epidural pressure were measured and related to rectal and oesophageal temperatures. The brain temperature was significantly higher than that of the rectum at normotemperature. The temperature gradients lessened during heating. At maximum rectal temperature (plateau) small differences between the left and right hand sides of the brain were seen, the temperatures being 0.4 degrees C and 0.3 degrees C higher than the rectal temperature, respectively. During the 2-h plateau period the difference between brain and oesophageal temperature became progressively smaller. The mean epidural pressure decreased slightly during the course of the treatment, but remained within the normal range of 1.2 +/- 0.4 KPa (8.7 +/- 2.5 mm Hg). From this investigation may be concluded that (1) the cerebral temperature is reflected better by the oesophageal than by the rectal temperature and (2) the epidural pressure does not increase during whole body hyperthermia for 2 h at a rectal temperature of up to 42.5 degrees C.

Assessing Body Temperature - Temporal Artery
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...
