Avaliação da concordância entre diferentes termômetros na aferição da temperatura corporal de crianças

Abstract

Introdução: Os termômetros feitos com mercúrio, ainda utilizados, têm alto risco tóxico para o indivíduo e o meio ambiente. Busca-se o termômetro ideal que deverá substituir os termômetros de mercúrio. O objetivo deste estudo é avaliar a concordância entre os termômetros eletrônicos axilar e instantâneos (auricular e cutâneo frontal) com os termômetros eletrônico retal e axilar de mercúrio na aferição da temperatura corporal de crianças. Métodos: Estudo transversal realizado no Serviço de Pediatria do Hospital de Clínicas de Porto Alegre, em amostra de conveniência de crianças cujas temperaturas foram medidas sequencialmente com termômetros eletrônicos e axilar de mercúrio. Para as comparações, foi utilizada a análise de Bland e Altman, avaliando médias de diferenças de temperaturas (MDT) e intervalos de confi ança de 95% (IC95%) de até 0,2°C. Resultados: Foram avaliadas 20 crianças febris e 43 eutérmicas, com idades entre um mês e dois anos, totalizando 633 aferições da temperatura corporal. Houve concordância parcial entre os termômetros axilar de mercúrio aos três minutos e axilar eletrônico, com MDT de -0,02°C e IC95% de -0,73°C a 0,68°C, e entre os termômetros eletrônicos retal e axilar de mercúrio aos três minutos, com MDT de -0,12°C e IC95% de -1,08°C a 0,84°C. Conclusões: Os termômetros eletrônicos instantâneos cutâneo frontal e auricular não apresentaram boa concordância, enquanto o termômetro eletrônico axilar apresentou a melhor concordância com o termômetro retal, sendo aquele considerado o melhor substituto do termômetro axilar de mercúrio para a aferição da temperatura corporal de crianças.

Introduction: Mercury thermometers, though still used, have a high toxic risk for humans and the environment. The ideal thermometer is sought to replace mercury thermometers. The aim of this study was to assess the correlation of axillary and instantaneous electronic thermometers (ear and forehead) with rectal and axillary mercury thermometers in measuring body temperature of children. Methods: Cross-sectional study conducted in the Department of Pediatrics, Hospital de Clinicas de Porto Alegre, in a convenience sample of children whose temperatures were measured sequentially with electronic and axillary mercury thermometers. For comparisons, Bland and Altman’s analysis was used to evaluate differences in mean temperatures (MDT) and confi dence intervals of 95% (CI 95%) of up to 0.2 °C. Results: Twenty feverish children and 43 euthermic children, aged between one month and two years, were evaluated, with a total of 633 measurements of body temperature. There was partial concordance between the axillary mercury and electronic thermometer at three minutes, with MDT -0.02 °C and CI 95% of -0.73 ° C to 0.68 °C, and between electronic rectal and axillary mercury thermometers at three minutes, with MDT -0.12 °C and 95% CI of -1.08 ° C to 0.84 °C. Conclusions: The instantaneous electronic ear and forehead thermometers did not show good agreement, while the axillary electronic thermometer showed the best agreement with the rectal thermometer, being considered the best substitute for axillary mercury thermometer to measure body temperature of children.
