Wire-reinforced endotracheal tube
To the Editor,
Wire-reinforced endotracheal tubes (WRETs) have a layered structure in which metal wire is embedded in the wall of the tube shaft. This structure makes the tube resistant to kinking caused by angulated forces and improves patient safety . WRETs are useful for head and neck surgery during which kinking of the tube is likely to occur . However, the use of a WRET may be associated with several problems causing the partial or total occlusion of the tube. There are numerous reports of obstruction of WRETs due to dissection of the layered structure [3, 4], patient bite [2, 5], or compression by surgical devices . We herein report a very rare case in which a WRET became kinked and obstructed at its “wireless” portion.
Certain types of WRETs have a “wireless” portion that potentially causes kinking of the tube. The endotracheal tube must be kept at an adequate angle to avoid kinking, even when using a wire-reinforced tube.
