The Asena PK can be operated in TIVA or TCI modes in anaesthesia applications. I think some of the benefits of the drug used with these pumps (propofol/diprivan) are that it can be used for induction and maintenance, it's available generically hence it is now relatively cheap, it's fast-acting and quickly metabolised therefore convenient for some cases, I guess, since patient induction and post-operative recovery is fast with relatively few side-effects. Can anyone elaborate? I have little knowledge of anaesthesia.
