BACKGROUND: We explored whether positioning patients in a 25° back-up sniffing position improved glottic views and ease of intubation. METHODS: In the first part of the study, patients were intubated in the standard supine sniffing position. In the second part, the back of the operating table was raised 25° from the horizontal by flexion of the torso at the hips while maintaining the sniffing position. The best view obtained during laryngoscopy was assessed using the Cormack and Lehane classification and Percentage of Glottic Opening (POGO) score...

BACKGROUND: The benefit of cricoid pressure during tracheal intubation is still debated and, due to its potential negative impact on laryngeal views, its routine use is questioned. The goal of this study was to estimate its impact on laryngeal view. METHODS: All patients intubated in the prehospital setting were included. Three different propensity score (PS) models were used and compared in terms of the balance achieved between those patients who received cricoid pressure and those who did not...

BACKGROUND: Simulation-based training (SBT) has developed into an established method of medical training. Studies focusing on the education of medical students have used simulation as an evaluation tool for defined skills. A small number of studies provide evidence that SBT improves medical students' skills in the clinical setting. Moreover, they were strictly limited to a few areas, such as the diagnosis of heart murmurs or the correct application of cricoid pressure. Other studies could not prove adequate transferability from the skills gained in SBT to the patient site...

INTRODUCTION: Non-iatrogenic trauma to the airway is rare and presents a significant challenge to the anaesthetist. Although guidelines for the management of the unanticipated difficult airway have been published, these do not make provision for the 'anticipated' difficult airway. This systematic review aims to inform best practice and suggest management options for different injury patterns. METHODS: A literature search was conducted using Embase, Medline, and Google Scholar for papers after the year 2000 reporting on the acute airway management of adult patients who suffered airway trauma...

To assess the degree to which cricoid pressure (Sellick manoeuvre) actually compresses the oesophagus, we measured the effect of cricoid pressure and paralaryngeal pressure on the outer anteroposterior diameter of the upper oesophagus with ultrasound in 39 healthy volunteers. The mean (SD) outer anteroposterior oesophageal diameter was 0.77 (0.11) cm with no pressure, 0.79 (0.13) cm with the application of cricoid pressure of 30 N and 0.68 (0.12) cm with the application of paralaryngeal pressure of 30 N (p < 0...

STUDY OBJECTIVE: Central venous access is indicated for transduction of central venous pressure and the administration of inotropes in the perioperative period. The right internal jugular vein (RIJV) is cannulated preferentially over the left internal jugular vein (LIJV). Cannulation of the LIJV is associated with a higher complication rate and a perceived increased level of difficulty when compared with cannulation of the RIJV. Possible explanations for the higher complication rate include a smaller diameter and more anterior position relative to the corresponding carotid artery (CA) of the LIJV compared with the RIJV...

INTRODUCTION: Patients at risk for microaspiration during elective intubation often receive cricoid pressure in the hopes of mitigating such risk. However, there is scarce evidence to either support or reject this practice. The objective of this investigation was to assess the effect of cricoid pressure on microaspiration and to inform the potential feasibility of conducting a larger, more definitive clinical trial. METHODS: This was a pilot randomized clinical trial set in the operating rooms of a tertiary referral hospital between August and October of 2014...

BACKGROUND: Choosing an appropriately sized endotracheal tube (ETT) is important in pediatric patients as an inappropriately sized ETT may result in multiple endotracheal intubation attempts or excessive pressure on the tracheal mucosa with the potential for airway damage. Although age-based formulas are generally used with choice of an ETT based on the internal diameter (ID), measurements of the outer diameter (OD) of the ETT would seem to be a more scientific approach to determine the proper size of an ETT...

BACKGROUND: Peroral endoscopic myotomy (POEM) is a novel method of treating achalasia of the esophagus. Very little data are available to guide the anesthesia providers caring for these patients. The anesthetic challenges are primarily related to the risk of pulmonary aspiration. There is also a potential risk of pneumomediastinum, pneumoperitoneum, subcutaneous, or submucosal emphysema, as a result of carbon dioxide tracking into the soft tissues surrounding the esophagus and lower esophageal sphincter...

Oropharyngeal dysphagia due to upper esophageal sphincter (UES) dysfunction is commonly encountered in the clinical setting. Selective experimental perturbation of various components of the deglutitive apparatus can provide an opportunity to improve our understanding of the swallowing physiology and pathophysiology. The aim is to characterize the pharyngeal and UES deglutitive pressure phenomena in an experimentally induced restriction of UES opening in humans. We studied 14 volunteers without any dysphagic symptoms (7 men, 66 ± 11 yr) but with various supraesophageal reflux symptoms...

Since the risk of pulmonary aspiration was recognized in obstetric anesthesia in 1930's, numerous efforts have been made to reduce the incidence and severity of perioperative pulmonary aspiration: preoperative fasting, preoperative assessment of risk factors in perioperative pulmonary aspiration, emptying the stomach, rapid-sequence induction of anesthesia with cricoid pressure, and the use of a cuffed tracheal tube. With these efforts, the incidence of pulmonary aspiration has been reduced drastically, and aspiration is now rare...
