Verification of tracheal tube position by fibre-optic bronchoscopy was evaluated in 20 critically ill adult patients. The distance between the carina and the tube was measured by direct visualization with a fibre-optic bronchoscope and compared with the corresponding measurement obtained from a concomitant chest radiograph. The measured values did not(More)
OBJECTIVE To examine whether patients assessed for initiation of oral intake only by Facial-Oral Tract Therapy had a greater risk of developing aspiration pneumonia during neurorehabilitation than patients assessed by Fibreoptic Endoscopic Evaluation of Swallowing. DESIGN Randomized controlled trial. SETTING Specialized, national neurorehabilitation(More)
PRIMARY OBJECTIVE To extend previous observations by investigating if differences exist in time to initiation or to recovery of total oral intake in patients with acquired brain injury assessed by either Facial-Oral Tract Therapy (F.O.T.T.) or Fibreoptic Endoscopic Evaluation of Swallowing (FEES) and to investigate whether other factors influence these(More)
Serotonin is a vasoactive amine. It is formed in the chromaffin cells in the small intestine and is inactivated in the liver and lungs. The remainder is taken up in the thrombocytes so that only minimal quantities are found free in the plasma. The peripheral effect of serotonin occurs probably exclusively by means of a release of amine from the thrombocytes(More)
Serotonin is a vasoactive amine which is considered to play a pathogenetic role in systemic hypertension on account of the peripharal vasotonic effect of serotonin. The central serotoninergic neurones excitatory influence of the sympathetic tone may, however, be a contributory cause. Urapidil is a selective S1-serotonic receptor-agonist with alpha-blocking(More)
Neurogenic oropharyngeal dysphagia (NOD) is a frequent condition in neurological patients admitted to the ICU, particularly in patients with brainstem lesions. The CNS damage itself can predispose to dysphagia, but also the treatment and preventive measures may predispose to and exacerbate the condition. Frequent pneumonia in a neurological patient is a(More)
In Denmark, early rehabilitation of acquired head injuries is centralised in two centres, each covering half the country as uptake area. The Regional Hospital Hammel Neurocenter (HN), which covers the western half of Denmark, traditionally receives patients for rehabilitation after discharge from the intensive care unit (ICU). In collaboration with the(More)
The accuracy of intra-arterial blood pressure measurement is dependent on the dynamic characteristics of the transducer. Specifications made by the manufacturers are often misleading. Four different transducers are tested in a clinically relevant setting. The resonance frequencies of all the transducers were found to be acceptable.
OBJECTIVE The aim of this study was to determine if external subglottic air flow (ESAF) influences swallowing frequency in severely dysphagic tracheotomized patients with brain injury. METHODS Ten patients were recruited at the neurological intensive care unit. The ESAF intervention was provided through the standard cuffed suction aid tracheotomy tube,(More)
