Body surface infrared thermometry in patients with central venous cateter-related infections

Abstract

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°C versus -0.2±0.5ºC; p=0.36), and the mean temperature on the catheter area minus that on the forehead (mean ± standard deviation: -0.2±0.5°C versus -0.1±0.5ºC; p=0.3) resulted in negative values. Moreover, in infected patients, higher values were obtained on the catheter area (95%CI: 36.6-37.5ºC versus 36.3-36.5ºC; p<0.01) and by temperature subtractions: catheter area minus contralateral region (95%CI: -0.17 - +0.33ºC versus -0.33 - -0.20ºC; p=0.02) and catheter area minus forehead (95%CI: -0.02 - +0.55ºC versus -0.22 - -0.10ºC; 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.

Complicações infecciosas associadas ao cateter venoso central totalmente implantável

“…22 In this study, articles that evaluated this place of insertion regarding the risk of infections were not included. , catheter-related infection 9,11,16 and infection of the subcutaneous pouch 20 were the most prevalent infections in the studies, with a predominance of gram-negative bacteria, such as Staphylococcus aureus 12,14,16,19,20 and Sthaphylococcus epidermis. 16,20 In most cases, the catheter had to be removed and the causative agent had to be removed.…”

“…In all cases, peripheral blood cultures were negative and all affected patients were treated successfully. 19,2015 Data were collected from 39 patients, 75% of patients hospitalized in a clinical unit and 25% in an Intensive Care Unit. The mean age was 57 years.…”

“…16,17 The other investigations were carried out among isolated cases of Pantoea agglomerans contamination 18 , assessment of the body temperature close to the insertion of the catheter suspected of infection 19 and a single randomized clinical trial comparing two types of solutions for totally implantable catheter blockage. It should be noted that the majority of the studies obtained a considerable and relevant number of participants (over 100), except for four studies that obtained reduced samples (n = 7; 39; 59 and 72).…”

Centrinių Venų Kateterizacija Operacinėje Ir Jos Sąsaja Su Kraujo Infekcijomis

“…Prieš trečiojo kateterio pašalinimą taip pat buvo stebimi vietiniai uždegimo požymiai: paraudimas, pakilusi odos temperatūra kateterio įkišimo vietoje. Tai yra vieni iš pirmųjų klinikinių simptomų, galinčių parodyti, kad centrinės venos kateteris yra kolonizuotas mikroorganizmų [14]. Pašalinus šį kateterį, buvo paimtas pasėlis, kuris sutapo su kraujo pasėliu.…”

Application of infrared thermography in diagnosing peripherally inserted central venous catheter infections in children with cancer

“…Although there are several publications that describe the use of infrared thermography in diagnosing infections and thrombosis (Silvah et al 2015, Oya et al 2016, Kacmaz et al 2017, there is little information in the literature about its possible application in oncological child patients fitted with CVC.…”
