Catheter mounts-EGBAT

Created: 26/4/2010

Catheter mounts are adaptors that connect the tracheal tube to the end of the anaesthetic breathing system. Various connectors fit between the distal end and the tracheal tube. The proximal end is of standard 22 mm taper. Connectors are 15 mm in size distally, and they fit to any standardised 15/22 mm equipment.

Some incorporate a capped port for tracheobronchial suction and insertion of fibreoptic instruments.

AAGBI Guidelines for checking anaesthetic equipment:

BREATHING SYSTEM

1. Check all breathing systems which are to be employed. They should be visually and manually inspected for correct configuration and assembly. Check that all connections within the system and to the anaesthetic machine are secured by ‘push and twist’. Ensure that there are no leaks or obstructions in the reservoir bags or breathing system and that they are not obstructed by foreign material. Perform a pressure leak test on the breathing system by occluding the patient-end and compressing the reservoir bag. Breathing systems should be
protected at the patient-end when not in use to prevent the intrusion of foreign bodies.

2. Bain-type and circle co-axial systems - Perform an occlusion test on the inner tube and check that the adjustable exhaust valve, where fitted, can be fully opened and closed.

3. Check the correct operation of the unidirectional valves in a circle system.

4. If it is intended to use very low fresh gas flows in a circle breathing system, there must be a means to analyse the oxygen and vapour concentration in the inspiratory limb. (Under other circumstances, these may be monitored at the anaesthetic machine fresh gas outlet.)

5. A new, single-use bacterial/viral filter and angle piece/catheter mount must be used for each patient. It is important that these are checked for patency and flow, both visually and by ensuring gas flow through the whole assembly when connected to the breathing system.

 

EGBAT Report


Trusts must ensure that narrow-bore PBC (patient breathing circuit) components remain wrapped when delivered to anaesthetic areas. Where components are cleaned, decontaminated, sterilised and presented for reuse,
Trusts should ensure that they are wrapped after they have been cleaned. Trusts should ensure
that all components (whether single-use or re-packed) carry a warning notice as described above.
