Previously active in the mid-1990s, Canadian Airway Focus Group (CAFG) studied unanticipated difficult airway and made recommendations on management a 1998 publication. The CAFG has since reconvened to examine more recent scientific literature management. Group's mandate for this article was arrive at updated practice of unconscious/induced patient whom or failed tracheal intubation is encountered.Nineteen clinicians with backgrounds anesthesia, emergency medicine, intensive care joined...
Tracheal intubation in coronavirus disease 2019 (COVID-19) patients creates a risk to physiologically compromised and attending healthcare providers. Clinical information on airway management expert recommendations these are urgently needed. By analysing two-centre retrospective observational case series from Wuhan, China, panel of international experts discussed the results formulated consensus for tracheal COVID-19 patients. Of 202 undergoing emergency intubation, most were males (n=136;...
Abstract Background Accurate tools for the noninvasive detection of hepatic steatosis are needed. The Controlled Attenuation Parameter ( CAP ) specifically targets liver using a process based on transient elastography. Methods Patients with chronic disease and body mass index BMI ≥28 kg/m 2 underwent biopsy stiffness measurement LSM simultaneous determination FibroScan ® M probe. performance diagnosing compared was assessed areas under receiver operating characteristic curves AUROC )....
Appropriate planning is crucial to avoid morbidity and mortality when difficulty anticipated with airway management. Many guidelines developed by national societies have focused on management of encountered in the unconscious patient; however, little guidance appears literature how best approach patient an difficult airway. To review this other subjects, Canadian Airway Focus Group (CAFG) was re-formed. With representation from anesthesiology, emergency medicine, critical care, CAFG members...
Since the last Canadian Airway Focus Group (CAFG) guidelines were published in 2013, airway management literature has expanded substantially. The CAFG therefore re-convened to examine this and update practice recommendations. This second of two articles addresses evaluation, decision-making, safe implementation an strategy when difficulty is anticipated. members, including anesthesia, emergency medicine, critical care physicians assigned topics search. Searches run Medline, EMBASE, Cochrane...

Background A correctly performed cricothyroidotomy may be lifesaving in a cannot-ventilate, cannot-intubate situation. However, many practicing anesthesiologists do not have experience with cricothyroidotomy. The purpose of this study was to determine the minimum training required perform 40 s or less mannequins. Methods After informed consent, participants were shown demonstration video and asked 10 consecutive procedures on mannequin using preassembled percutaneous dilational set. Each...
Preoperative testing has been criticized as having little impact on perioperative outcomes. We conducted a randomized, single-blind, prospective, controlled pilot study to determine whether indicated preoperative can be eliminated without increasing the incidence of adverse events in selected patients undergoing ambulatory surgery.One thousand sixty-one eligible were randomized either have or no testing. In group, received testing: complete blood count, electrolytes, glucose, creatinine,...
Objective To determine the influence of positive end-expiratory pressure (PEEP) on intracranial and cerebral perfusion pressure. Design Neurosurgical intensive care patients requiring monitoring mechanical ventilation were studied in a randomized, controlled study. Setting Tertiary care, neurosurgical unit. Patients Eighteen enrolled had posttraumatic head injuries (n = 9), subarachnoid hemorrhage 7), obstructive hydrocephalus 1), intracerebral unknown cause =1). Interventions PEEP levels 5,...
Objective. The purpose of this study was to evaluate the feasibility sonography in identifying anatomic structures upper airway and describe their appearance on sonography. Methods. We enrolled 24 healthy volunteers, placed them supine with head extended neck flexed (the "sniffing" position), performed a systematic sonographic examination from floor mouth suprasternal notch. Results. were able visualize all relevant participants using either linear or curved transducer oriented 1 3 planes:...
Background Adverse events such as pharyngolaryngeal complications are indicators of quality patient care. Use manometry to limit the laryngeal mask airway (LMA) intracuff pressure is not currently a routine practice. This double-blind randomized trial compared in patients managed with manometers LMA (<44 mmHg) under Method Two hundred consenting who underwent ambulatory surgery were randomly allocated pressure-limiting and care groups. Anesthesia was induced propofol fentanyl, maintained...
There is conflicting evidence as to whether obesity and neck circumference are predictors of difficult intubation in the surgical population. In addition, cut-off related has not been clearly identified.The primary study objective was determine were morbidly obese patients. Secondary outcomes included mask ventilation.A prospective, noninterventional study.Canadian tertiary care centre between October 2012 August 2013.A total 104 patients (BMI ≥40 kg m(-2)) study. Eighty-eight women 16 men....
Morbidly obese patients undergoing general anesthesia are at risk of hypoxemia during induction. High-flow nasal oxygenation use induction prolongs safe apnea time in nonobese surgical patients. The primary objective our study was to compare time, between given high-flow or conventional facemask induction, morbidly patients.Research ethics board approval obtained. Elective ≥18 years with body mass index ≥40 kg·m were included. Patients severe comorbidity, gastric reflux disease, known...
In Brief The purpose of this study was to determine the preferences Canadian anesthesiologists in difficult intubation and cannot intubate–cannot ventilate (CICV) situations. Using a mailed survey, we asked their for comfort level using (a) alternative airway devices scenario (b) infraglottic CICV scenario. Chi-square analysis Student's t-test were used categorical continuous variables. Nine-hundred-seventy-one 2066 surveys returned. scenario, preferred lighted stylet (45%), fiberoptic...
The Supreme laryngeal mask airway (LMA) is a new single-use polyvinyl chloride supraglottic device that combines the functionality of ProSeal and Fastrach airways. High oropharyngeal leak pressures are important as they indicate protection, feasibility positive pressure ventilation likelihood successful LMA placement. not well established versus ProSeal. This study was designed to compare safety efficacy in elective ambulatory procedures.Hospital ethics board approval obtained. One hundred...
Objectives The aim of this study was to compare airway anatomic parameters as measured by sonography and computed tomography (CT). Methods Fifteen adult patients underwent CT followed the anterior neck under standard conditions. A radiologist an anesthesiologist with experience in imaging examined scans performed measurements specific parameters: distance posterior surface tongue, thickness submental region, hyomental distance, depth epiglottis from skin (above below hyoid bone), thyrohyoid...
Fast-track cardiac anesthesia, using low-dose narcotics combined with short-acting anesthetic and sedative agents, facilitates early tracheal extubation after surgery. The incidence of awareness this technique has not been investigated previously. purpose study was to prospectively investigate the intraoperative explicit memory events during fast-track anesthesia.Data were collected over a 4-month period from 617 consecutive adult patients undergoing surgery at university hospital.
