Medical science has long made the improbable probable, saving lives and improving quality of life. Upon the introduction of medical devices that can deliver safe quantities of the poisonous gas nitric oxide to help patients with respiratory and other illnesses, the FDA requested ASTM Committee F29 on Anesthetic and Respiratory Equipment to provide standards for these devices. Dr. Daniel Supkis and Mark Graber explain the delicate process of delivering NO to patients and how ASTM standards now in development will increase the safety of this procedure.

The head and neck cancer patient should be in the best possible medical condition before facing surgery, bearing in mind the status of the tumor and the urgency of the procedure. Careful assessment of the patient's upper airway will enable the anesthesiologist to select an appropriate course of action to secure the airway before the operation begins. In many cases, the patient can be safely intubated after the induction of general anesthesia. In other situations, the patient may require an examination of the airway while awake with the aid of sedation and topical analgesia to determine the safest intubation technique. If the patient has evidence of a difficult airway, a flexible fiberoptic-guided intubation may be indicated to secure the airway in the awake patient patient before general anesthesia is induced. Some patients with severe airway obstruction or large, bulky supraglottic tumors usually undergo an initial tracheostomy with local anesthesia to secure the airway. Following surgery, extubation of the patient's trachea requires careful attention and may have to be performed over a jet-ventilating stylet.
