Objective:
To identify the skin temperature in different body areas of hospitalised individuals in the surgical unit, without risk of developing a pressure ulcer (PU).
Methods:
A descriptive, correlational and cross-sectional study, carried out May-October 2017, in a surgical unit of a university hospital in southern Brazil. Temperature was measured at the bony prominences including scapula, elbow, trochanters and heels, on both sides of the body, as well as occipital and sacral regions.
Results:
A total of 230 patients took part in the study. All regions of the body measured presented differences in temperatures. The sacral region presented the highest mean temperature (34.2±0.1°C). Patients (aged 18-59 years) had higher skin temperatures in the sacral region than older patients (aged 60-88 years). There was a symmetry in temperatures on both sides of the body. There was a low degree of correlation between age, room temperature, room humidity and skin temperature in some body regions.
Conclusion:
The study established mean values for skin temperature in specific body regions in patients without risk of developing a PU, hospitalised in a surgical unit. It also demonstrates how skin temperature can be used as a clinical parameter in practice to support the prevention of PUs.

Factors may include:
01:19Assessing 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...

01:14Assessing Body Temperature - Axilla
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...

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...
01:14Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
