Oral condition of critical patients and its correlation with ventilator-associated pneumonia: a pilot study

Condição oral de pacientes críticos e sua correlação com pneumonia associada a ventilação mecânica: um estudo piloto


INTRODUCTION: Literature has reported inadequate oral hygiene conditions in Intensive Care Unit (ICU) patients and the occurrence of Ventilator-associated pneumonia in about 9%-27% of all intubated patients. OBJECTIVE: The aim of this study was to evaluate ICU patient's oral conditions and correlate this with the presence of ventilator-associated pneumonia. MATERIAL AND METHOD: Twenty-three patients were categorized in the following way: with periodontal disease and ventilator-associated pneumonia, with periodontal disease and without ventilator-associated pneumonia, without periodontal disease and with ventilator-associated pneumonia, and with neither periodontal disease nor ventilator-associated pneumonia. The periodontal disease index, plaque index, and decay-missing-filled index were used in the assessment. RESULT: There was no statistically significant difference in the incidence of periodontal disease with respect to ventilator-associated pneumonia, but the number of teeth and surfaces with attachment loss above 4 mm was always greater in patients with ventilator-associated pneumonia. CONCLUSION: The extent of periodontal disease may contribute to the onset of ventilator-associated pneumonia. However, studies with a larger sample are needed to validate this relationship.

INTRODUÇÃO: A literatura vem relatando condições inadequadas de higiene oral de pacientes em unidade de terapia intensiva (UTI) e a ocorrência de Pneumonia associada à ventilação mecânica em cerca de 9%-27% de todos os pacientes intubados. OBJETIVO: O objetivo deste estudo foi avaliar condições orais de pacientes críticos e correlacionar com a presença de pneumonia associada à ventilação mecânica. MATERIAL E MÉTODO: Vinte e três pacientes foram categorizados da seguinte maneira: com a doença periodontal e com pneumonia associada à ventilação mecânica, com doença periodontal e sem pneumonia associada à ventilação mecânica, sem doença periodontal e com pneumonia associada à ventilação mecânica e sem doença periodontal e sem pneumonia associada à ventilação mecânica. Foram utilizados na avaliação os índices de placa, de doença periodontal e índice de cariados, perdidos e obturados. RESULTADO: Não houve diferença estatisticamente significante na incidência da doença periodontal em relação à pneumonia associada à ventilação mecânica, mas o número de dentes e superfícies com perda de inserção acima de 4 mm sempre foi maior em pacientes com pneumonia associada à ventilação mecânica. CONCLUSÃO: A extensão da doença periodontal pode contribuir para o aparecimento de pneumonia associada à ventilação mecânica. No entanto, são necessários estudos com uma amostra maior para validar essa relação.
