BACKGROUND: Rapid sequence induction (RSI) for endotracheal intubation is a technique widely used in anaesthesia, emergency and intensive care medicine to secure an airway in patients deemed at risk of pulmonary aspiration. Cricoid pressure is conceptually used to reduce the risk of aspiration by compressing the oesophagus. OBJECTIVES: To identify and evaluate all randomized controlled trials (RCTs) involving participants undergoing elective or emergency airway management via RSI and compare participants who have cricoid pressure administered with participants who do not have cricoid pressure administered...

BACKGROUND: Establishing a definitive airway, defined as a tube placed in the trachea with cuff inflated below the vocal cords, is standard of care in pre-hospital airway management of the trauma patient. However, in this setting, and using manual in-line stabilisation of the neck, success rate of intubation by inexperience providers is suboptimal. The use of supraglottic airway devices that allow blind tracheal intubation has been suggested as an alternative method by the Advanced Trauma Life Support (ATLS) programme of the American College of Surgeons...

STUDY OBJECTIVE: We describe the operators, techniques, success, and adverse event rates of adult emergency department (ED) intubation through multicenter prospective surveillance. METHODS: Eighteen EDs in the United States, Canada, and Australia recorded intubation data onto a Web-based data collection tool, with a greater than or equal to 90% reporting compliance requirement. We report proportions with binomial 95% confidence intervals (CIs) and regression, with year as the dependent variable, to model change over time...

INTRODUCTION: Our objective is to evaluate the resident learning curves for direct laryngoscopy (DL) and GlideScope® video laryngoscopy (GVL) over the course of an emergency medicine (EM) residency training program. METHODS: This was an analysis of intubations performed in the emergency department (ED) by EM residents over a seven-year period from July 1, 2007 to June 30, 2014 at an academic ED with 70,000 annual visits. After EM residents perform an intubation in the ED they complete a continuous quality improvement (CQI) form...

OBJECTIVES: In the critically ill undergoing urgent endotracheal intubation by direct laryngoscopy, multiple attempts are often required with a higher complication rate due to the urgency, uncontrolled setting, comorbidities, and variability in expertise of operators. We hypothesized that Glidescope video laryngoscopy would be superior to direct laryngoscopy during urgent endotracheal intubation. DESIGN: Single-center prospective randomized controlled trial. SETTING: Beth Israel Medical Center, an 856-bed urban teaching hospital with a 16-bed closed medical ICU...

STUDY OBJECTIVE: We investigate a new technique for the emergency airway management of patients with altered mental status preventing adequate preoxygenation. METHODS: This was a prospective, observational, multicenter study of patients whose medical condition led them to impede optimal preintubation preparation because of delirium. A convenience sample of emergency department and ICU patients was enrolled. Patients received a dissociative dose of ketamine, allowing preoxygenation with high-flow nonrebreather mask or noninvasive positive pressure ventilation (NIPPV)...

BACKGROUND: Direct laryngoscopy (DL) has long been the gold standard for tracheal intubation in emergency and trauma patients. Video laryngoscopy (VL) is increasingly used in many settings and the purpose of this study was to compare its effectiveness to direct laryngoscopy in trauma patients. Our hypothesis was that the success rate of VL would be higher than that of DL. METHODS: Data were collected prospectively on all trauma patients, from January 2008 to June 2011, who were intubated emergently in an academic level I trauma center...

PURPOSE: External laryngeal manipulation (ELM) is used to get better laryngeal view during direct laryngoscopy. This study was designed to test the hypothesis that ELM done by the intubating anesthetist (laryngoscopist) offers the best laryngeal view for tracheal intubation. MATERIALS AND METHOD: A total of 160 patients underwent different surgical procedures were included in this study. Percentage of glottic opening (POGO) score and Cormack and Lehane scale were used as outcome measures for comparison between different laryngoscopic views...

STUDY OBJECTIVE: To determine which nostril is more suitable for nasotracheal intubation in patients with normal patency of both nostrils. DESIGN: Prospective, randomized clinical trial. SETTING: Operating room of a university medical center. PATIENTS: 191 ASA physical status 1 and 2 patients scheduled for elective oral surgery requiring general anesthesia with nasotracheal intubation. INTERVENTIONS: Patients were randomized to two groups to undergo nasotracheal intubation through the right nostril (Group R; n = 96) or the left nostril (n = 95)...

BACKGROUND: Effective airway management is a priority in early trauma management. Data on physician pre-hospital tracheal intubation are limited; this study was performed to establish the success rate for tracheal intubation in a physician-led system and examine the management of failed intubation and emergency surgical cricothyroidotomy in pre-hospital trauma patients. Failed intubation rates for anaesthetists and non-anaesthetists were compared. METHODS: A retrospective database review was conducted to identify trauma patients undergoing pre-hospital advanced airway management between September 1991 and December 2012...

Fiberoptic intubation (FOI) is an effective technique for establishing airway access in patients with both anticipated and unanticipated difficult airways. First described in the late 1960s, this approach can facilitate airway management in a variety of clinical scenarios given proper patient preparation and technique. This paper seeks to review the pertinent technology, clinical techniques, and indications for and complications of its use. The role of FOI in airway management algorithms is discussed. Evidence is presented comparing FOI to other techniques with regard to difficult airway management...

In this article, recent literature related to airway management in the ambulatory surgery setting is reviewed. Practical pointers to improve clinical success and avoid complications of newer airway management techniques are provided.

During nasotracheal intubation, the tracheal tube passes through either the upper or lower pathway in the nasal cavity, and it has been reported to be safer that the tracheal tube passes though the lower pathway, just below the inferior turbinate. We evaluated the use of a nasogastric tube as a guide to facilitate tracheal tube passage through the lower pathway, compared with the 'conventional' technique (blind insertion of the tracheal tube into the nasal cavity). A total of 60 adult patients undergoing oral and maxillofacial surgery were included in the study...

Extraglottic airway devices (EAD) have become an integral part of anesthetic care since their introduction into clinical practice 25 years ago and have been used safely hundreds of millions of times, worldwide. They are an important first option for difficult ventilation during both in-hospital and out-of-hospital difficult airway management and can be utilized as a conduit for tracheal intubation either blindly or assisted by another technology (fiberoptic endoscopy, lightwand). Thus, the EAD may be the most versatile single airway technique in the airway management toolbox...

In 1961, Sellick popularized the technique of cricoid pressure (CP) to prevent regurgitation of gastric contents during anesthesia induction. In the last two decades, clinicians have begun to question the efficacy of CP and therefore the necessity of this maneuver. Some have suggested abandoning it on the grounds that this maneuver is unreliable in producing midline esophageal compression. Moreover, it has been found that application of CP makes tracheal intubation and mask ventilation difficult and induces relaxation of the lower esophageal sphincter...

BACKGROUND: Optimal out of hospital cardiac arrest (OHCA) airway management strategies remain unclear. We compared OHCA outcomes between patients receiving endotracheal intubation (ETI) versus supraglottic airway (SGA), and between patients receiving [ETI or SGA] and those receiving no advanced airway. METHODS: We studied adult OHCA in the Cardiac Arrest Registry to Enhance Survival (CARES). Primary exposures were ETI, SGA, or no advanced prehospital airway placed...
