Clinical Presentations
Upper Airway Obstruction (see [[Obstructive Lung Disease]]): usually is unlikely to produce significant upper airway obstruction, however, cases with post-op respiratory failure have been reported [Upper airway involvement in Parkinson’s disease resulting in postoperative respiratory failure. Can J Anaesth. 1995 Apr;42(4):344-7] [Reversibility of upper airway obstruction after levodopa therapy in Parkinson’s disease. Chest. 1989 Jul;96(1):210-2]
