Training in Swallowing Prevents Aspiration Pneumonia in Stroke Patients with Dysphagia

This study investigated the frequency of aspiration pneumonia in conscious stroke patients fed by a family member and examined the effect of introducing training in swallowing techniques by nurses. A total of 96 consecutive patients presenting with dysphagia due to acute stroke were included in the study. Patients presenting between January 2000 and July 2003 ( n = 48) were fed orally by a family member given general nursing information (group A), whereas those presenting between August 2003 and March 2005 ( n = 48) were fed orally by an experienced nurse trained in specific swallowing techniques (group B). All patients were examined daily for the presence of aspiration pneumonia. The incidence of aspiration pneumonia was 33.3% in group A and 6.3% in group B ( P < 0.05). The incidence of aspiration pneumonia in dysphagic stroke patients who are orally fed is still high. Training in swallowing during oral feeding offers clear protection against pneumonia in conscious stroke patients.

Oropharyngeal dysphagia in long-term care: misperceptions of treatment efficacy

The assessment and management of patients in long-term care who have oropharyngeal dysphagia has developed into an apparently complex and distinct field of practice. It is unfortunate that it lacks an evidence base, the efficacy of treatment is not established, and many clinicians are unfamiliar with appropriate and effective interventions because of a lack of training. Some commonly used interventions are not only ineffective but potentially hazardous. Physicians must become more familiar with the assessment process and appropriate management.

Pneumonia in acute stroke patients fed by nasogastric tube

BACKGROUND

Aspiration pneumonia is the most important acute complication of stroke related dysphagia. Tube feeding is usually recommended as an effective and safe way to supply nutrition in dysphagic stroke patients.

OBJECTIVE

To estimate the frequency of pneumonia in acute stroke patients fed by nasogastric tube, to determine risk factors for this complication, and to examine whether the occurrence of pneumonia is related to outcome.

METHODS

Over an 18 month period a prospective study was done on 100 consecutive patients with acute stroke who were given tube feeding because of dysphagia. Intermediate outcomes were pneumonia and artificial ventilation. Functional outcome was assessed at three months. Logistic regression and multivariate regression analyses were used, respectively, to identify variables significantly associated with the occurrence of pneumonia and those related to a poor outcome.

RESULTS

Pneumonia was diagnosed in 44% of the tube fed patients. Most patients acquired pneumonia on the second or third day after stroke onset. Patients with pneumonia more often required endotracheal intubation and mechanical ventilation than those without pneumonia. Independent predictors for the occurrence of pneumonia were a decreased level of consciousness and severe facial palsy. The NIH stroke scale score on admission was the only independent predictor of a poor outcome.

CONCLUSIONS

Nasogastric tubes offer only limited protection against aspiration pneumonia in patients with dysphagia from acute stroke. Pneumonia occurs mainly in the first days of the illness and patients with decreased consciousness and a severe facial palsy are especially endangered.
