TUBES, CATHETERS AND DRAINS
TUBES
Without endotracheal tubes, modern anaesthesia would be unthinkable.
The traditional tubes of the Magill pattern are made of red mineralized rubber.
Except these, all have an inflatable cuff near the distal tip to protect the lower respiratory tract from soiling as well as providing an air-tight seal.
Each number refers to the internal diameter of the tube in millimeters.
These in the past have been made of rubber and recycled in practice by autoclaving.
All these instruments and nasogastric tubes are now made of non-reactive plastic marerial and come pre-sterilized in packs.
These tubes are all disposable and thus do not require recycling.
The tubes in use are:
· Cuffed oral endotracheal tube
· Uncuffed oral endotracheal tube
· Negus tracheostomy tube
· Chevalier-Jackson tracheostomy tube
Tracheostomy tube
Identification points of tracheostomy tube
· It has the outer tube that is taped to the neek and always stays in the trachea.
· An inner tube that can be taken out for cleaning.
· An abdurator required at the time of introduction.
