Effect of Cricoid Pressure on the Success of Endotracheal Intubation with a Lightwand

Abstract

The lightwand cannot be recommended for the first attempt at intubation where cricoid pressure is being applied because the time to successful intubation is significantly prolonged, and the failure rate for the first attempt at lightwand intubation is 13%.

No evidence for decreased incidence of aspiration after rapid sequence induction

“…Less difficulty has been reported with the Bullard laryngoscope. [112][113][114] Although CP has been reported to make airway management more difficult, Turgeon et al 115 were unable to confirm such an effect in an RCT of 700 patients. The view at laryngoscopy and the incidence of failed intubation at 30 sec was not different in control and cricoid pressure groups.…”

La compression cricoïdienne rend l’intubation endotrachéale moins facile à l’aide de la laryngoscope fibroscopique (WuScope System™)

“…[2][3][4] For example, in a randomized study of lightwand-assisted tracheal intubation with and without cricoid pressure in adults, time to successful intubation was prolonged and the failure rate for the first attempt at intubation was increased in the cricoid pressure group. 5 Similarly, in a double-blind randomized study of fibrescopeaided tracheal intubation through the laryngeal mask airway (LMA) with and without cricoid pressure in adults, it was impossible to intubate the trachea in 85% of the cricoid pressure group. 6 The WuScope System™ (WSS; Pentax Precision Instruments, Orangeburg, NY, USA) is a fibreoptic intubating device, combining rigid laryngoscope blades with a flexible fibrescope.…”

Combination of Airway Scope and bougie for a full-stomach patient with difficult intubation caused by unanticipated anatomical factors and cricoid pressure

“…Flexible fiberoptic intubation may not be available. A light-guided intubation is sometimes difficult during cricoid pressure [13]. Cricoid pressure can impede proper insertion of a LMA or an ILMA [14].…”
