Risk factors of misaspiration in acute stroke patients

Objective:To investigate the incidence rate and the risk factors of misaspiration in acute stroke patients.Method:Seventy-one patients with acute stroke from April 2005 to January 2006 were analyzed in this study.They were divided into two groups according to the results of Fiberoptic Endoscopic Examination of Swallowing (FEES):misaspiration group and non-misaspiration group.Multivariate logistic regression analysis was used to analyze the independent risk factors of post-stroke misaspiration.Result:The incidence rate of misaspiration in acute stroke patients was 50.7% (36/71).Of them,13 patients had silent misaspiration.Univariate analysis indicated that age,history of stroke and severity of stroke were correlated significantly with post-stroke misaspiration (P0.05).However,the multivariate Logistic regression analysis selected the severity of stroke(OR=5.778,95%CI 1.123—29.737) and history of stroke(OR=3.302,95%CI 1.174—9.293) as the independent risk factors of post-stroke misaspiration.Conclusion:Misaspiration is a common problem in acute stroke patients.Severe stroke (NIHSS10) and history of stroke are both the independent risk factors of post-stroke misaspiration
