RESUMO Objetivos: comparar os valores de temperatura corporal timpânica e axilar dos pacientes críticos antes e depois da realização do banho no leito tradicional e a seco. Métodos: ensaio clínico randomizado crossover, aberto, realizado com 50 pacientes críticos adultos. Todos os pacientes receberam os dois tipos de banho no leito. Os valores da temperatura timpânica e axilar foram mensurados no início e fim dos banhos. Utilizou-se o Teste de Wilcoxon ou t de Student pareado. Resultados: predominaram os pacientes idosos e do sexo masculino. Não houve diferença significativa entre as medianas de temperatura timpânica aferidas durante o banho no leito tradicional (p=0,707) e a seco (p=0,101). As médias da temperatura axilar reduziram ao final dos banhos (p=0,001), sendo 36,12ºC no banho tradicional e 35,92ºC no banho a seco. Conclusões: o banho no leito, independentemente do método utilizado, provocou redução na temperatura axilar dos pacientes críticos.

ABSTRACT Objectives: to compare tympanic and axillary body temperature values of critical patients before and after the traditional and dry bed bath. Methods: this is a randomized, open crossover clinical trial conducted with 50 adult critical patients. All patients received both types of bed bathing. The tympanic and axillary temperature values were measured at the beginning and end of the baths. The Wilcoxon test or paired Student’s t test was used. Results: elderly and male patients predominated. There was no significant difference between tympanic temperature medians measured during the traditional bed bath (p=0.707) and dry bath (p=0.101). Axillary temperature means reduced at the end of the baths (p=0.001), being 36.12ºC in the traditional bath and 35.92ºC in dry bath. Conclusions: bed bath, regardless of the method used, caused a reduction in critical patients’ axillary temperature.

RESUMEN Objetivos: comparar los valores de temperatura corporal timpánica y axilar de pacientes críticos antes y después del baño en la cama tradicional y seca. Métodos: ensayo clínico crossover, aleatorizado y abierto, realizado con 50 pacientes adultos críticos. Todos los pacientes recibieron ambos tipos de baños en la cama. Los valores de temperatura timpánica y axilar se midieron al inicio y al final de los baños. Se utilizó la prueba t de Student o Wilcoxon pareada. Resultados: predominaron los pacientes ancianos y varones. No hubo diferencia significativa entre las medianas de temperatura timpánica medidas durante el baño en la cama tradicional (p=0,707) y la seca (p=0,101). Las medias de temperatura axilar disminuyeron al final de los baños (p=0,001), siendo 36,12ºC en el baño tradicional y 35,92ºC en el baño seco. Conclusiones: el baño en cama, independientemente del método utilizado, provocó una reducción de la temperatura axilar de los pacientes críticos.

ABSTRACT Veterinary drug residues in bulk tank milk are important to all sectors of the dairy chain because they are one of the major factors which determine the safety of the final product. This study attempted to identify milk quality parameters that are associated with the occurrence of veterinary drug residues using multivariate principal component analysis (PCA). A total of 132 raw milk samples were collected from 45 dairy farms in the state of Minas Gerais - Brazil and analyzed for 42 analytes, including pyrethroids, macrocyclic lactones and antibacterials, using liquid chromatography coupled with mass spectrometry in tandem mode and gas chromatography with electron capture detection. Out of the 132 milk samples, 40 samples tested positive for at least one analyte (above the detection limit). The milk parameters associated with the antimicrobial residues by confirmatory tests were lactose and nonfat concentrations, as revealed by PCA. This analysis showed that fat and total solid concentrations, as well as the somatic cell and total bacteria counts were associated with macrocyclic lactone residues in bulk tank milk. A PCA assessing pyrethroid residues in bulk tank milk revealed that the lactose and nonfat solid concentrations and titratable acidity were inversely associated with these residues. Thus, the data analysis indicated that the veterinary drug residues were associated with certain milk quality parameters that can be used to target farms at higher risk of veterinary drug residue contamination for testing programs in combination with incentives, education and training programs to improve mammary health, milk hygiene and safety.
