Hemodynamic responses to tracheal intubation with laryngoscope versus lightwand
intubating device (TrachlightA(r)) in adults with normal airway.
This involves using transillumination of neck tissue by a lightwand
(Light Wand[TM] Orotracheal Lighted Stylet, Vital Signs Inc., NJ, USA).
Clinical assessment of awake endotracheal intubation using the lightwand
technique alone in patients with difficult airways.
A comparison of hemodynamic changes after endotracheal intubation using the lightwand
device and the laryngoscope in normotensive and hypertensive patients.
These techniques include deepening of anesthesia, newer techniques and instruments for laryngoscopy and intubation (lightwand
, styletoscope, and flexible fiberoptic endoscope), [7-9] omitting cholinergic premedication, and pre-treatment with vasodilators such as nitroglycerine, beta-blockers, calcium channel blockers, clonidine, and opioids with variable results.
technique is accompanied by less haemodynamic changes after tracheal intubation than the laryngoscopic technique in normotensive patients, but not in hypertensive patients.
A study on light-wand intubating laryngoscope versus direct laryngoscopy (with and without intubation) revealed that the lightwand
group had the same haemodynamic profile as the classical laryngoscopy without intubation (13).
Furthermore, they can provide an intubation conduit using a blind technique and by lightwand
, optical stylet, or fiber-optic guidance during airway resuscitation.[sup] If the supraglottic airway device fails to provide adequate gas exchange for a CICV patient, the option of emergency invasive airway access including transtracheal jet ventilation and surgical airway should be immediately performed.[sup], As the clinicians, we must remember that maintenance of oxygenation and ventilation is paramount during difficult airway management.
