Swallowing impairment after

When a topical gel, such as lidocaine viscous, is used for oral anestiiesia for die control of pain, the nurse instructs die patient not to eat food for 1 hour after use because local anestiiesia of die mouth or throat may impair swallowing and increase die possibility of aspiration. 

LSD is an ergot alkaloid. After synthesis, blotter paper or sugar cubes are sprinkled with the liquid and allowed to dry. When LSD is swallowed, psychoactive effects typically appear after 30 minutes and last 6-12 hours. During this time, subjects have impaired ability to make rational judgments and understand common dangers, which puts them at risk for accidents and personal injury. 

Pneumonia is a common complication in elderly patients confined to bed. Chest infection is particularly common after stroke because of impairment in swallow and cough reflex, poor respiratory movement and pulmonary embolism. The risks can be reduced by good nursing and chest physiotherapy. A pharyngeal airway may be required, particularly in drowsy patients or after a brainstem stroke, and ventilation may be considered in certain patients.
