Gum elastic bougie, capnography and apnoeic oxygenation

Abstract

The modification of the gum elastic bougie allows a more objective assessment of correct placement than the previous tactile method. The current design of bougie is unsuitable but can be modified.

Airway Injury During Anesthesia: A Closed Claims Analysis

“…on their article which supports previous work by Hochman [2] and Adnet [3]. It seems surprising that Drs Sorbello and Frova are reluctant to accept the evidence and modify the design of the device.…”

“…On the other hand, head elevation leads to flattening of the secondary curve (and reducing the angle of the vestibule axis to the horizontal) with little effect on the primary curve (Fig. Hochman [2] found the same result with a variety of straight blades. Therefore, the combination of head elevation and head and neck extension (i.e.…”

“…Consequently, it is not at all surprising that 54 patients (27%) in our study had either grade 3a, 3b or 4 view as inadequate view of larynx was one of the selection criteria. We found some evidence supporting the use of a carbon dioxide or oesophageal detection device for confirming introducer position [2,3]. The decision whether or not to use the Frova introducer was made by clinicians faced with poor laryngeal view.…”

A modification in the tube guide to facilitate retrograde intubation: A prospective, randomised trial

“…The tracheal tube was inserted into the guiding catheter and pushed into the trachea following which the guidewire and catheter were removed and the correct position of tracheal tube was confirmed by capnography. [78]…”

“…[9] Correct placement of tube guide into the trachea was confirmed by using capnography. [8] The guidewire was now removed from the nasal end and tracheal tube was advanced into the trachea. The tube guide was taken out and the correct position of the tracheal tube was reconfirmed using capnography.…”
