A Hydri. A Modified Endotracheal Tube Serving As A Long Tracheostomy Tube. The Internet Journal of Otorhinolaryngology. 2006 Volume 6 Number 1.
Tracheostomy is a life saving procedure, performed for a number of indications and on a wide spectrum of patients having a diverse anatomy of the neck. A surgeon performing tracheostomy on a patient having a large neck is always wary of the potential complications
I present a method of reducing the length of ETT to a suitable size while maintaining the integrity of the cuff and also a method of securing it in patients with a very thick neck.
Take a cuffed Portex® endotracheal tube of a size similar to that of a tracheostomy tube which you would otherwise use on the same patient. Mark the length required to safely reach the tracheal lumen. If the cuff pilot line is moulded to the ETT above this mark cutting through the tube will result in an incompetent cuff. Therefore carefully cut a sliver of plastic tube along the length of the cuff pilot line above the desired level. After an appropriate length has been achieved inflate the cuff to check its integrity. To make a flange, cut a flat rectangular strip from a firm plastic drip bag approx 1”x 3”. Make an aperture in its middle slightly smaller than the diameter of the ETT. Cut two holes on both ends for the strings to pass through. Remove the connector from the discarded top end of the ETT. Pass its tip through the central aperture of the improvised flange and firmly insert it in the cut ETT. Move the improvised flange to confirm that it is secured between the top of the ETT and the lower surface of the connector. The sliver of plastic cut along the cuff pilot line lies below the self made flange and prevents it from sliding down the tube. Your extra length modified tracheostomy tube is ready for use. (Fig.1) .A comparison of ETT, regular and modified tracheostomy tubes is also shown (Fig.2)
This modified tube helps maintain a secure airway in patients with a very thick neck till the oedema settles or until a longer tracheostomy tube is obtained.
