Hazards in use of anode endotracheal tube a case report and review.

While the design and manfacture of plastic tubes have been greatly improved in recent years, spiral-metal-bound latex tubes are still subject to a number of hazards, among them herniation of the intramural cuff-inflating tube into the lumen of the anode tube, preventing entry or exit of gases through the anode tube after cuff inflation. Problems may also occur at the bevel and at juctions. Until better-designed anode tubes are available, extra care is required in their use.
