    Sammanfattning : Swallowing disorders, termed ‘dysphagia’, are more common in the elderly but can also affect younger persons. Approximately, 8% of the world’s population suffers from dysphagia. A Texture Modified Diet (TMD), which increases bolus viscosity to adjust for the sluggish bolus handling mechanism, is the most common intervention. LÄS MER

  3. 7. A novel drug and device in anesthesia : with focus on breathing and upper airway physiology

    Författare :Åse Lodenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Anesthesia-related airway complications are associated with hypoxia due to inability to secure or maintain the airway with subsequent insufficient ventilation and gas exchange. This thesis has explored the impact on airway integrity and respiratory regulation of two anesthetic compounds frequently used for sedation and a novel principle for oxygenation in patients at risk of hypoxia, in order to further improve patient safety during sedation and induction of anesthesia.

  4. 8. Eating difficulties in elderly, focusing on patients with stroke

    Författare :Albert Westergren; Institutionen för hälsovetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; discharge; length of in-hospital stay; malnutrition; energy; alertness; ingestion; deglutition; dysphagia; eating; elderly care; rehabilitation; Nursing care; stroke; Gerontology; Gerontologi;

    Sammanfattning : The aim of this thesis was to describe eating difficulties and interventions to improve eating among elderly patients, especially those with stroke, to make comparisons between patients with dysphagia and those without (Papers I & II), those with and without assisted eating (Paper IV), and to analyse the relation between eating difficulties, nutritional status (Papers II-V), pressure ulcers (Paper IV), length of hospital stay and levels of independent living when discharged (Paper V). Eating difficulties were mainly assessed using structured observations. LÄS MER

  5. 9. Nerve lesions in pharynx : an aetiology of obstructive sleep apnoea

    Författare :Danielle Friberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : "Heavy snorers disease" is defined as the progression from habitual snoring to obstructive sleep apnoea (OSA). Apart from a significant weight gain, the aetiology underlying progression to a collapse of the upper airways during inspiration and sleep remains unclear. LÄS MER

  7. 10. Weight reduction and alcohol abuse in sleep apnea patients

    Författare :Pia Nerfeldt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Obstructive sleep apnea syndrome (OSAS) has an estimated prevalence of 2 percent in women and 4 percent in men. OSAS is characterized by repeated obstructive events of the pharyngeal upper airway during sleep. LÄS MER
