TIVA Administration Sets

[gasboy]

Hi

Here in the UK it's common to use a "Y" giving set with integral unidirection valves with an additional "lectro cath" type extention that connects to the patient.

Inbetween each case the extention is changed prior to each new patient.
Is this practice the same where you are?
Is it safe?
Has anyone seen papers or articles describing this practice as safe or unsafe?
