Resumo

Objective: To evaluate if body surface temperature close to the central venous catheter insertion area is different when patients develop catheter-related bloodstream infections. Methods: Observational cross-sectional study. Using a non-contact infrared thermometer, 3 consecutive measurements of body surface temperature were collected from 39 patients with central venous catheter on the following sites: nearby the catheter insertion area or totally implantable catheter reservoir, the equivalent contralateral region (without catheter), and forehead of the same subject. Results: A total of 323 observations were collected. Respectively, both in male and female patients, disregarding the occurrence of infection, the mean temperature on the catheter area minus that on the contralateral region (mean +/- standard deviation: -0.3+/-0.6 degrees C versus -0.2+/-0.5 degrees C; p=0.36), and the mean temperature on the catheter area minus that on the forehead (mean +/-standard deviation: -0.2+/-0.5 degrees C versus -0.1+/-0.5 degrees C; p=0.3) resulted in negative values. Moreover, in infected patients, higher values were obtained on the catheter area (95% CI: 36.6-37.5 degrees C versus 36.3-36.5 degrees C; p<0.01) and by temperature subtractions: catheter area minus contralateral region (95% CI: -0.17 - +0.33 degrees C versus -0.33 - -0.20 degrees C; p=0.02) and catheter area minus forehead (95% CI: -0.02 - +0.55 degrees C versus -0.22 - -0.10 degrees C; p<0.01). Conclusion: Using a non-contact infrared thermometer, patients with catheter-related bloodstream infections had higher temperature values both around catheter insertion area and in the subtraction of the temperatures on the contralateral and forehead regions from those on the catheter area.
