• Operative medications and the increased degree of muscular relaxation now requested by surgeons, especially where there is some predisposing factor to respiratory obstruction, all increase the responsibilities of the anesthetist to be aware of all methods to assist the patient's respiration while under anesthesia. When, after respiratory obstruction, all commonly applied methods of providing a clear airway have not been successful, or are unable to be accomplished, the insertion of an oxygen-carrying needle into the tracheal lumen may prevent a respiratory death. Oxygen saturation of the arterial blood, decreased to the point of cyanosis, may be reversed to normal or above within minutes after application of this technique and can be maintained for 30 minutes or more until the obstruction is alleviated. This is for emergency treatment only.
