The impact of cricoid pressure on laryngoscopy is unknown. We have developed a quantitative method of recording the laryngoscopic view using a rigid, zero‐degree endoscope. We found that an image matching the laryngoscopist's view could be obtained by positioning the endoscope along the laryngoscopist's ‘line of sight’. Photographing this image allowed us to measure laryngeal exposure. We set out to define the effect of cricoid pressure on laryngoscopy using this method. In 40 patients… Expand

Observational Clinical Trial
The goal of this study is to evaluate the effect of Sellick´s Maneuver, a firm pressure on the throat, just below the Adams apple, to occlude the esophagus, in order to prevent… Expand

InterventionProcedure
Videographic analysis of glottic view with increasing cricoid pressure force.
TLDR
Cricoid pressure application with increasing force resulted in a worse glottic view, as examined with the Pentax-AWS Video laryngoscope, and Clinicians should be aware that cricoid pressure affects laryngeal view with thepentax-awS and likely other video lARYngoscopes. Expand
Cricoid pressure with the Truview Evo2TM laryngoscope improves the glottic view
TLDR
When using the Truview Evo2TM laryngoscope with the patient’s head in the neutral position, application of CP improves the glottic view and is not associated with increased difficulty in intubation. Expand
Effect of Paratracheal Pressure on the Glottic View During Direct Laryngoscopy: A Randomized Double-Blind, Noninferiority Trial
TLDR
Paratracheal pressure was noninferior to cricoid pressure with respect to the effect on glottic view during direct laryngoscopy with a randomized, double-blind, non inferiority trial. Expand
Can force be used as a surrogate measure for difficult laryngoscopy? A reply
TLDR
This analysis demonstrates a remarkable association between force generated by the blade and the laryngoscopic view and suggests that the force required to perform the manoeuvre was the determining factor in the operator’s assessment of the lARYngoscopic ‘view’ and quality of the blade. Expand
[Video laryngoscopy for modified rapid sequence induction of anaesthesia: Sellick manoever with and without video laryngoscopic control].
TLDR
Visualisation of the larynx during RSI can be improved using VIL, and time to ETI is not decreased by use of video laryngoscopy-guided application of cricoid pressure. Expand
Does cricoid pressure have a detrimental impact on laryngoscopy and intubation?
Cricoid pressure is used in anaesthetic practice to prevent regurgitation during anaesthetic induction; it is also used by some paramedics. However, it may have a detrimental impact upon laryngoscopyExpand
Cricoid pressure with the Truview Evo2 TM laryngoscope improves the glottic view La pression cricoidienne avec le laryngoscope Truview Evo2 TM ameliore la visualisation glottique
TLDR
Evaluated the effect of cricoid pressure on laryngeal view and the ease of orotracheal intubation with the Truview Evo2 laryngoscope to improve glottic view found the effect was similar in the two groups. Expand
The effect of cricoid pressure on intubation facilitated by the gum elastic bougie *
TLDR
Ninety degree anti‐clockwise rotation of the tube was successful in all 23 patients (100%) with sham cricoid pressure and in 32/36 patients (89%) with 30 N cricoids pressure. Expand

TLDR
In this month’s issue of Anesthesia & Analgesia, Rice et al. explore the cricoidhypopharyngeal unit to determine whether cricoids pressure occludes the esophageal lumen when the latter is displaced lateral to the cervical spine. Expand
Cricoid pressure and laryngeal manipulation in 402 pre-hospital emergency anaesthetics: essential safety measure or a hindrance to rapid safe intubation?
TLDR
The results suggest that cricoid pressure should be removed if the laryngeal view obtained is not sufficient to allow immediate intubation and further manipulation of theLarynx is likely to improve the chances of successful tracheal tube placement. Expand

The effect of cricoid pressure and neck support on the view at laryngoscopy
TLDR
Cricoid pressure is likely to improve the view at laryngoscopy which may be further improved by applying it in an upward and backward direction and whether these views were improved with a firm foam rubber neck support is investigated. Expand
The effect of cricoid pressure on the cricoid cartilage and vocal cords: an endoscopic study in anaesthetised patients
TLDR
Cricoid occlusion was unrelated to age and body mass index but females were at greater risk and Associated difficulty in ventilation was present in 15 patients and 18/30 had vocal cord closure with associated difficult ventilation, at forces up to 44 N. Expand
The effects of single‐handed and bimanual cricoid pressure on the view at laryngoscopy
TLDR
Bimanual cricoid pressure should be the initial technique of choice during rapid sequence induction but, in a minority of cases, switching to a single‐handed technique may improve the laryngoscopic view. Expand
The effect of cricoid pressure application on airway patency.
  • K. Allman
  • Medicine
  • Journal of clinical anesthesia
  • 1995
TLDR
The use of manual cricoid pressure, even by experienced anesthetists, causes a degree of airway obstruction and can cause complete airway occlusion, and effect on airway patency is assessed. Expand
Cricoid pressure applied after placement of the laryngeal mask prevents gastric insufflation but inhibits ventilation.
TLDR
Although cricoid pressure applied after insertion of the laryngeal mask prevented gastric insufflation, it also decreased ventilation, and the inhibitory effect of cricoidal pressure on ventilation without support of the neck was greater than cricoids pressure with support ofThe neck. Expand
Airway obstruction with cricoid pressure and lateral tilt
TLDR
The effect of cricoid pressure and lateral tilt on airway patency during ventilation by facemask in a simulated obstetric setting and in both supine and tilted positions was studied. Expand
A novel method of measuring cricoid force.
TLDR
The validity of using floor scales to measure cricoid force applied by anaesthetic assistants is assessed and their use to an established training technique is compared. Expand
Upper oesophageal sphincter pressure and the effect of cricoid pressure
TLDR
Upper oesophageal sphincter pressure has been measured in 24 patients with a sleeve device and laryngoscopy made little difference to the effect of cricoid pressure except in one patient in whom it reduced the sphiffer pressure by 27 mmHg. Expand
Difficult tracheal intubation in obstetrics
TLDR
Frequency analysis suggests that, in obstetrics, the main cause of trouble is grade 3, in which the epiglottis can be seen, but not the cords, which is fairly rare, and can be helpful as part of the training before starting in the maternity department. Expand
Difficult Tracheal Intubation: A Retrospective Study
TLDR
There is a correlation between the degree of difficulty and the anatomy of the oropharynx in the same patient, and any screening test which adds to ability to predict difficulty in intubation must be welcomed, as failure to intubate can potentially lead to fatality. Expand
