Dysphagia following acute thalamic haemorrhage: clinical correlates and outcomes.
OBJECTIVE
A high incidence of dysphagia is seen during the acute phase of cerebral haemorrhage; however, there have been only rare reports of dysphagia caused by thalamic haemorrhage. We studied cases of thalamic haemorrhage during the acute period after hospitalization and examined the relationships between the frequency of dysphagia, stroke focus and haematoma volume.


METHODS
There were 113 subjects in this study, selected from 247 patients with thalamic haemorrhage who visited our rehabilitation centre. Patients were excluded if they had a history of dementia, stroke, confusion, epileptic seizure, surgical treatment or tracheotomy. We conducted a bedside swallowing assessment (BSA) by using the repetitive saliva swallowing test and modified water swallowing test. The relationships between oral intake condition at the time of hospital discharge, discharge destination (e.g. home), type of haematoma and haematoma volume were examined.


RESULTS
Abnormal BSA was found in 55% of the subjects (n = 62) with thalamic haemorrhage. Existence of a swallowing disorder was related to haematoma type and haematoma volume. A regular diet was possible in 41% of the subjects (n = 46). Age, haematoma volume, initial BSA evaluation and cognitive function had the greatest influence on a subject's ability to eat a general diet at the time of hospital discharge. Of those subjects in whom the initial BSA evaluation was normal, 70% were able to eat a regular diet at discharge. However, of those in whom the BSA evaluation was abnormal, >70% were discharged with enteral feeding. Furthermore, the rates of discharge to home were 95% in patients who could eat a regular diet and 30% in patients who needed enteral feeding.


CONCLUSIONS
In the acute phase of thalamic haemorrhage, dysphagia was found in a high percentage of subjects. Dysphagia is associated with a poor prognosis for early hospital discharge.
