Background Cricoid pressure (CP) is often used during general anesthesia induction to prevent passive regurgitation of gastric contents. The authors used magnetic resonance imaging to determine the anatomic relationship between the esophagus and the cricoid cartilage (“cricoid”) with and without CP. Methods Magnetic resonance images of the necks of 22 healthy volunteers were reviewed with and without CP. Esophageal and airway dimensions, distance between the midline of the vertebral body and… Expand

Cricoid pressure provides incomplete esophageal occlusion associated with lateral deviation: a magnetic resonance imaging study.
TLDR
Effective application of cricoid pressure by an experienced operator frequently resulted in lateral deviation of the esophagus and incomplete occlusion of esophageal lumen. Expand
Cricoid cartilage and esophagus: CT scan study of the dynamic variability of their relative positions
TLDR
It can be seen that the E is clearly displaced with regard to the CC, that this displacement is favored by extension, and the extension position of the head produces more displacement of the E but should preserve the containment of the cricoid pressure if the authors consider the thickness of theE wall. Expand
Using Ultrasonography to Assess the Effectiveness of Cricoid Pressure on Esophageal Compression.
TLDR
The potential ineffectiveness of cricoid pressure on esophageal compression is highlighted, calling into question the utility of this maneuver. Expand
Alignment of Cricoid Cartilage and Esophagus and Its Potential Influence on the Effectiveness of Sellick Maneuver in Children
TLDR
This is the first pediatric study on the rate and degree of esophageal displacement from the airway at the level of the cricoid cartilage andateral displacement occurred at a significantly greater rate in the younger children compared with the older children. Expand
Cricoid Pressure Results in Compression of the Postcricoid Hypopharynx: The Esophageal Position Is Irrelevant
TLDR
The location and movement of the esophagus is irrelevant to the efficiency of the Sellick’s maneuver (CP) in regard to prevention of gastric regurgitation into the pharynx and compression of the alimentary tract occurs with midline and lateral displacement of the cricoid cartilage relative to the underlying vertebral body. Expand
Ultrasound guided paralaryngeal pressure versus cricoid pressure on the occlusion of esophagus: a crossover study
TLDR
Comparing the effectiveness of cricoid pressure (CP) and paralaryngeal pressure (PLP) on occlusion of eccentric esophagus in patients under general anesthesia (GA) and the prevalence of patients with central or eccentricEsophagus both before and after GA, and the success rate of CP in occluding centrally located esophagine in patients post GA.

The Effectiveness of Cricoid Pressure for Occluding the Esophageal Entrance in Anesthetized and Paralyzed Patients: An Experimental and Observational Glidescope Study
TLDR
The current study provides additional visual and mechanical evidence supporting a success rate of at least 95% by using a cricoid force of 30 N to occlude the esophageal entrance in anesthetized and paralyzed normal adult patients. Expand
Ultrasound Assessment of the Effectiveness of Cricoid Pressure
Background and AimsThe application of cricoid pressure (CP) during rapid sequence induction to prevent regurgitation of gastric contents has been questioned by many studies in the past decade. ThereExpand
CRICOID PRESSURE : MORE RITUAL THAN EFFECTIVE MEASURE ? 19 RC 3
In 1961 Sellick introduced the concept of cricoid pressure (CP) [1]. In his publication, he described the technique of using CP during induction of anaesthesia in 26 patients whom he considered atExpand

The cricoid cartilage and the esophagus are not aligned in close to half of adult patients
TLDR
There is a 49% frequency of some degree of lateral displacement of the esophagus relative to the cricoid cartilage (“cricoid”) using computed tomography images of normal necks. Expand
Postcricoid region and cervical esophagus: normal appearance at CT and MR imaging.
TLDR
Knowing of the normal appearance and variations of the postcricoid region and cervical esophagus is essential in detecting abnormalities in these areas. Expand
Cricoid Pressure: Teaching the Recommended Level
TLDR
This model represents an easy and practical means of teaching the application of the optimal level of force to practitioners and assistants and was proposed to determine whether with education and practice, anesthesia providers and assistants could be taught a recommended cricoid pressure. Expand
Nasogastric tubes and cricoid pressure
TLDR
In all cases of bloody tap which the authors have so far examined there has also been a large haematoma within the superficial fascial spaces of the spine, and similar, but smaller, haem atomas were also present in two of three patients following uncomplicated epidural. Expand
Linear measurements in 2-dimensional pelvic floor imaging: the impact of slice tilt angles on measurement reproducibility.
TLDR
Identical measurements made on radiologic images can vary widely and slice acquisition must be standardized to avoid errors in data comparison. Expand

TLDR
Ananesthetists and paramedical personnel familiar with Sellick's manoeuvre were tested yielding results which indicate an unacceptably wide variation in performance in each group. Expand
Cricoid pressure: knowledge and performance amongst anaesthetic assistants
TLDR
Performance, as assessed by the variability of forces applied and proportion of subjects applying force within the authors' target range, was improved markedly by providing simple instruction about the required force in an understandable form and practical training in the application of a target force on a simulator.

This edition of the ultimate anatomy atlas for clinical reference, patient education and personal study includes surface anatomy plates added to the beginning of each regional section and significant number of normal radiographic images have been included. Expand
If nothing goes wrong, is everything all right? Interpreting zero numerators.
TLDR
The occurrence of "no events" seems to be viewed as very different both quantitatively and qualitatively from the occurrence of one or more events, so it is useful to look into some of the statistical and psychological issues that influence the occurrence. Expand
