Subglottic high frequency jet ventilation in surgical management of bilateral vocal fold paralysis after thyroidectomy.
Lesion of the recurrent laryngeal nerves as a consequence of thyroid surgery results in bilateral vocal fold paralysis and respiratory obstruction. The initial treatment involves ensuring an adequate airway and it ranges from tracheostomy to endo-extralaryngeal laterofixating operations in general anesthesia. Subglottic high frequency jet ventilation (HFJV) is an alternative ventilatory approach in airway surgery. ⋯ No complications secondary to the ventilation technique were observed. No perioperative tracheotomy was necessary. It is concluded that subglottic HFJV is an easy and safe way to ventilate patients with bilateral vocal fold paralysis when endoscopic intervention is performed.

Airway management in the intensive care unit (ICU) is a challenging procedure and is frequently associated with life threatening complications. The incidence of difficult intubations ranges from 10% to 22%, depending on the setting and the patients in need of endotracheal intubation. Multiple attempts are often needed to secure the airway. ⋯ Parts of this protocol are appropriate staffing, pre-oxygenation and strategies to avoid cardiovascular complications. In conclusion, high practical skill of airway management is needed in critically ill patients. Monitoring such as capnography and alternative equipment for securing the airway is not just mandatory in the operating room but also in the ICU.

The number of indications for lung collapse during different procedures is rising. Difficult upper airway is more often encountered with the need for single lung ventilation. ⋯ An alternative technique is exchanging the single-lumen for a double-lumen tube using an airway exchange catheter. When there is a tracheostomy in place, an independent bronchial blocker is recommended.

The Fourth National Audit Project (NAP4) was set up by the Royal College of Anaesthetists and Difficult Airway Society to provide an insight into major complications of airway management in the United Kingdom. The NAP4 found that one serious airway complication such as death, brain damage, the need for surgical airway or unexpected intensive care admission, was reported for every 5500 general anaesthetics. Most of the events happened during daytime to a senior experienced clinicians. ⋯ Awake fibreoptic intubation was indicated and not performed in a significant number of reported incidents. Thirty percent of serious airway complications were associated with extubation or removal of laryngeal mask airway at the end of anaesthesia. The findings of the NAP4 have the potential to significantly influence airway management practice of all anaesthetists irrespective of where in the world they practice anaesthesia.

Two clinical forms of the "white spot" syndrome in patients with posterior uveitis in definitive and presumable ocular sarcoidosis were analyzed. Group 1 was characterized by periphlebitis and discrete white spots around the vein of the retina, so-called "candle-wax", whereas group 2 showed yellow-orange solitary nodules located at the choroid, i.e. multifocal choroiditis. Visual acuity and the severity of clinical presentation were assessed in both groups. ⋯ T-test for independent samples yielded a statistically significant difference between the groups (p = 0.02). A statistically significant difference in visual acuity was the result of vasculitis in the group with the "candle-wax" phenomenon, which is associated with retinal vasculitis and causes cystoid macular edema and reduction of visual acuity. Complications such as cataract, glaucoma and neovascularization, which also decrease visual acuity, were more frequent in group 1.
