Resumo: | Background: The measurement of sodium, potassium and chloride is widely used in clinical practice. It can be done through a serum or gasometric sample. The ease of blood collection and the fast availability of results would make gasometry the ideal method. However, the literature data on the accuracy of gasometry are not consensual, thus, the current method of choice is the serum sample. We intended to compare the accuracy of sodium, potassium and chloride measurement between the gasometry and the serum ionogram. Methods: Prospective observational study of children aged 28 days to 17 years who underwent elective surgery at a Pediatric Surgery Service during one year. During the perioperative period, 3 laboratory evaluations were performed with ionogram analysis in a serum sample and gasometry and their results were compared. Results: 65 children with a median age of 10 years (IQR 3.6-15), 77% male. 161 determinations of sodium, 154 of potassium and 143 of chloride were obtained. There was a mean difference in sodium, potassium and chloride values between the two methods of: 1±1.89 mmol/L, 0.3±0.19mmol/L and -5±1.81 mmol/L (p <0.001). There was a strong correlation between sodium (r=0.64) and chloride (r=0.78) and very strong with potassium (r=0.9). It was possible to establish a linear regression and obtain a correction factor between the two methods. Conclusions: There was a strong correlation between the two methods, therefore, both can be used in clinical practice. A correction factor can be applied to the gasometry’s potassium and chloride results. |

A facilidade de colheita e a rapidez no resultado tornariam a gasometria no método ideal, contudo, a literatura disponível não é consensual quanto à sua precisão. Este trabalho pretende estudar a precisão da avaliação do ionograma efetuada pela gasometria. Métodos: Estudo observacional prospetivo de crianças com idades entre 28 dias e 17 anos submetidas a cirurgia eletiva num Serviço de Cirurgia Pediátrica, durante um ano. No peri-operatório foram realizadas 3 avaliações laboratoriais com análise de sódio, potássio e cloro numa amostra sérica e na gasometria e os respetivos resultados foram comparados. Resultados: 65 crianças com idade mediana de 10 anos (IQR 3,6-15), 77% do sexo masculino. Obtiveram-se 161 determinações de sódio, 154 de potássio e 143 de cloro. Verificou-se uma diferença média na medição de sódio, potássio e cloro entre os dois métodos, respetivamente, de 1±1,89mmol/L, 0,3±0,19mmol/L e -5±1,81mmol/L (valor-p<0,001). Encontrou-se uma correlação forte nas medições de sódio (r=0,64) e cloro (r=0,78) e muito forte na de potássio (r=0,9). Para todos, foi possível estabelecer uma regressão linear e obter um fator de correção que permite a conversão entre os dois métodos. Conclusões: Verificou-se uma forte correlação entre os dois métodos o que permite concluir que ambos podem ser usados na prática clínica, podendo ser utilizado um fator de correção quando utilizada a gasometria, particularmente na avaliação do potássio e cloro.Sociedade Portuguesa de Anestesiologia2021-07-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.25751/rspa.23929eng0871-6099Sousa, Francisco José deCochito Sousa, SofiaVaz, SaraAbecasis, Franciscoinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-23T15:34:52Zoai:ojs.revistas.rcaap.pt:article/23929Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:04:19.693307Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
