Clinical Trial Summary

This is a pilot study which aims to show the temperatures measured on body surface with an infrared thermometer on inpatients who need a central venous catheter (CVC) for medical care. Because the local temperature could be altered, at least during local infectious processes, seems to be reasonable to think that this approach could be helpful to its early diagnosis.

Description:

By convenience sampling, it was expected that during 4 months, a minimum of 30 inpatients of the metabolic, clinical or intensive care wards, at the Clinical Hospital of Ribeirão Preto Medical School, São Paulo, Brazil, would have their data collected

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Body temperature measured with a non-contact infrared thermometer.	It was used a non-contact forehead infrared thermometer, model IR200® (Extech, USA). Fifteen minutes after bath, mobilization or warm or cold compresses, 3 measurements were obtained at the following sites: 1) close to CVC insertion, 2) at the equivalent contralateral site of CVC and 3) at the forehead. The variables values will be displayed in form of descriptive statistics (mean, standard deviation, standard error, proportions of the observations, confidence intervals) according to: sex, central venous catheter type (guide wire or port-a-cath), location of insertion, reason of the central venous catheter indication (like parenteral nutrition or antibiotics), number of catheter lumens and age. Also, the mean differences between the three locations measured will be presented.	15 minutes after bath, mobilization or warm or cold compresses	No
