    Bougies or capnography?

    We read with interest the concerns

    raised about the bougie hold-up

    sign causing airway trauma [1]. The

    use of this sign in determining the

    position of the bougie is superior to

    tracheal clicks alone, as shown by

    Kidd and colleagues [2]. In the arti-

    cle by Paul and colleagues [3], the

    novel use of a traffic light depth

    gauge actively discourages the use

    of hold-up as an endpoint, relying

    solely on clicks. If we are to avoid

    the hold-up sign, then the accuracy

    of bougie positioning may be

    reduced, and perhaps it is time to

    look for another way of confirm-

    ing bougie position. The use of cap-

    nography, as described by Millar

    and colleagues [4], may offer such

    confirmation.

    Preloading bougies

    We read with interest the report of

    airway trauma related to the use of

    gum-elastic bougies during airway

    management [1]. The accompany-

    ing editorial succinctly summarises

    the past, present and possible future

    of the humble bougie [2].

    In our bariatric anaesthesia

    practice, we have found wide use

    for the bougie and often use it elec-

    tively in super-morbidly obese

    patients. The bougie is very useful

    when there is an occlusive prolifera-

    tion of oropharyngeal soft tissues,

    as seen in obstructive sleep apnoea

    and obesity, keeping the time to

    tracheal intubation as short as

    possible and avoiding having to

    implement a rescue Plan B [3].

    We have developed a simple

    innovation for use of the bougie in

    bariatric anaesthesia (that may be

    applicable to other situations), the

    Preloaded Bougie Technique, in

    which the bougie is electively pre-

    loaded into the tracheal tube and

    held in place by the pilot balloon

    (Fig. 1). After induction of anaes-

    thesia and under direct laryngos-

    copy, the anaesthetist holds the

    bougie and inserts its curved distal
