Objetivo: Identificar a incidência de alterações glicêmicas no pós-operatório imediato em pacientes adultos e idosos submetidos à cirurgia cardíaca. Metodologia: Estudo observacional, longitudinal e quantitativo, realizado em um hospital escola de grande porte do interior do estado do Rio Grande do Sul. Foram incluídos pacientes com idade igual ou maior que 18 anos e internados durante o pré-operatório da cirurgia cardíaca eletiva. A coleta de dados ocorreu de março a novembro de 2024, utilizando um questionário estruturado em três etapas: período pré-operatório, intraoperatório e pós-operatório imediato. A análise foi realizada por meio de estatística descritiva simples e inferencial. Resultados: Foram incluídos 109 participantes, sendo a maioria do sexo masculino (66,1%). Identificou-se que a cirurgia mais realizada foi a de troca valvar (51,4%). Identificou-se incidência de hipoglicemia de 2,8% e hiperglicemia de 76,1%, sendo a glicemia mediana no pós-operatório imediato de 169,0 mg/dL. Conclusão: Identificou-se uma incidência de hipoglicemia de 2,8% e hiperglicemia de 76,1% em adultos e idosos submetidos à cirurgia cardíaca.
ABSTRACT
Objective: To identify the incidence of glycemic variability in the immediate postoperative period among adult and older patients undergoing cardiac surgery. Methodology: An observational, longitudinal, quantitative study conducted at a large teaching hospital in the interior of the state of Rio Grande do Sul, Brazil. Patients aged 18 years or older who were hospitalized during the preoperative period of elective cardiac surgery were included. Data collection took place from March to November 2024 using a structured questionnaire in three stages: preoperative, intraoperative, and immediate postoperative periods. Data analysis was performed using simple descriptive and inferential statistics. Results: The study included 109 participants, mostly male (66.1%). The most frequently performed surgery was valve replacement (51.4%). An incidence of hypoglycemia of 2.8% and hyperglycemia of 76.1% was identified, with a median immediate postoperative period blood glucose level of 169.0 mg/dL. Conclusion: An incidence of hypoglycemia of 2.8% and hyperglycemia of 76.1% was identified among adults and older patients undergoing cardiac surgery in the immediate postoperative period.
