Resumo

JUSTIFICATIVA E OBJETIVOS: As relações entre valores alterados de glicemia e complicações perioperatórias na população de idosos submetidos a procedimentos cirúrgicos ainda não são conhecidas. O objetivo deste estudo foi avaliar a associação entre glicemia de jejum e morbimortalidade perioperatória em pacientes cirúrgicos idosos. MÉTODO: Foram analisados os prontuários de pacientes acima de 60 anos submetidos a diversos procedimentos cirúrgicos num período de seis meses, divididos de acordo com os valores de glicemia de jejum nos grupos: < 100 mg.dL-1, entre 100 e 125 mg.dL-1 e > 126 mg.dL-1. Foram analisados quanto à idade, estado físico (ASA), história prévia de diabete melito (DM) e tratamento e risco cardíaco perioperatório cirurgia-específico. Por meio de análise univariada e de um modelo de regressão logística multivariada, foi avaliada a relação entre os desfechos (freqüência de complicações pós-operatórias [CPO] e óbitos) e as variáveis: glicemia de jejum, história prévia de DM, estado físico (ASA) e risco cardíaco. RESULTADOS: Houve associação estatística apenas entre os grupos glicêmicos e as variáveis estado físico e história prévia de DM. Todas as variáveis estudadas revelaram associação estatística em relação à maior freqüência de CPO e óbitos, exceto a variável presença de história prévia de DM, que não apresentou relação com óbitos. No modelo de regressão logística multivariada, houve associação entre as variáveis risco cardíaco e glicemia em função da ocorrência de CPO, enquanto apenas as variáveis estado físico e risco cardíaco revelaram associação estatística em função da ocorrência de óbitos. CONCLUSÕES: Este estudo retrospectivo mostrou que para a população de pacientes idosos estudada houve associação significativa entre glicemias acima de 100 mg.dL-1 e morbimortalidade perioperatória.

Abstract

BACKGROUND AND OBJECTIVES: The relationship between altered blood glucose levels and perioperative complications in elderly patients undergoing surgeries are not known. The objective of this study was to evaluate the association between fasting blood glucose levels and perioperative morbimortality in elderly surgical patients. METHODS: Medical records of patients older than 60 years undergoing several surgical procedures during a 6-month period were analyzed and divided, according to fasting blood glucose levels, in three groups: < 100 mg.dL-1, between 100 and 125 mg.dL-1, and > 126 mg.dL-1. Age, physical status (ASA), history of diabetes mellitus (DM), and treatment and perioperative surgery-specific cardiologic risk were analyzed. Using univariate analysis and a model of multivariate logistic regression, the relationship among the outcome (frequency of postoperative complications [POC] and death) and the following variables: fasting blood glucose, history of DM, physical status (ASA), and cardiac risk, was evaluated. RESULTS: A statistical association was demonstrated only among the three groups and physical status and history of DM. All parameters studied demonstrated a statistical relationship regarding the higher frequency of POC and death, except for the parameter history of DM, which did not demonstrate any relationship with deaths. In the multivariate logistic regression model, there was an association between cardiac risk and blood glucose levels with POC, while only physical status and cardiac risk demonstrated a statistical association with death. CONCLUSIONS: This retrospective study demonstrated a significant association among blood glucose levels above 100 mg.dL-1 and postoperative morbimortality in the elderly.
