Risk factors for overt aspiration in adult ICU patients
Objective To determine the risk factors for overt aspiration in adult ICU patients and to provide reference for identifying the high-risk patient and reducing overt aspiration.Methods A total of 798 adult ICU patients were selected.Univariate analysis and logistic regression analysis were performed to identify the risk factors for overt aspiration.Results The incidence of overt aspiration was 16.9%.Mechanical ventilation,gastric residual volume,intra-abdominal pressure,aspiration history and vomiting were risk factors for overt aspiration in adult ICU patients(all P<0.05).Conclusion Adult ICU patients are at risk for overt aspiration.At-tention should be paid to those with mechanical ventilation,aspiration history and vomiting,and interventions should be taken to reduce gastric residual volume and intra-abdominal pressure,thus to decrease overt aspiration.
