OBJECTIVE: To assess interruptions in chest compressions associated with advanced airway placement during cardiopulmonary resuscitation (CPR) of out-of-hospital cardiac arrest (OHCA) victims. METHODS: The method used was observational analysis of prospectively collected clinical and defibrillator data from 339 adult OHCA victims, excluding victims with <5 minutes of CPR. Interruptions in CPR, summarized by chest compression fraction (CCF), longest pause, and the number of pauses greater than 10 seconds, were compared between patients receiving bag valve mask (BVM), supraglottic airway (SGA), endotracheal intubation (ETI) via direct laryngoscopy (DL), and ETI via video laryngoscopy (VL)...

PURPOSE: We sought to evaluate the utility of waveform capnography (WC) in detecting paralysis, by using apnoea as a surrogate determinant, as compared with clinical gestalt during rapid sequence intubation. Additionally, we sought to determine if this improves the time to intubation and first pass success rates through more consistent and expedient means of detecting optimal intubating conditions (ie, paralysis). METHODS: A prospective observational cohort study of consecutively enrolled patients was conducted from April to June 2016 at an academic, urban, level 1 trauma centre in New York City...

We studied prospectively the reliability of clinical methods, end-tidal carbon dioxide (ETCO(2)) detection, and the esophageal detector device (EDD) for verifying tracheal intubation in 137 adult patients in the emergency department. Immediately after intubation, the tracheal tube position was tested by the EDD and ETCO(2) monitor, followed by auscultation of the chest. The views obtained at laryngoscopy were classified according to the Cormack grade. Of the 13 esophageal intubations that occurred, one false-positive result occurred in the EDD test and auscultation...

INTRODUCTION: Fresh frozen cadavers are effective training models for airway management. We hypothesised that residual carbon dioxide (CO2) in cadaveric lung would be detectable using standard clinical monitoring systems, facilitating detection of tracheal tube placement and further enhancing the fidelity of clinical simulation using a cadaveric model. METHODS: The tracheas of two fresh frozen unembalmed cadavers were intubated via direct laryngoscopy. Each tracheal tube was connected to a self-inflating bag and a sidestream CO2 detector...

BACKGROUND: Tracheal intubation is commonly performed outside the operating theatre and is associated with higher risk than intubation in theatre. Recent guidelines and publications including the 4th National Audit Project of the Royal College of Anaesthetists have sought to improve the safety of out-of-theatre intubations. METHODS: We performed a prospective observational study examining all tracheal intubations occurring outside the operating theatre in nine hospitals over a 1 month period...

BACKGROUND: Airway complications occur more frequently outside the operating theatre and in emergency situations. Capnography remains the gold standard for confirming correct endotracheal tube placement, retaining high sensitivity and specificity in cardiac arrest. The 2010 European Resuscitation Council guidelines for adult advanced life support recommended waveform capnography in this setting. We investigated current UK practice relating to the availability and use of this technology during cardiac arrest...

STUDY OBJECTIVE: To determine the incidence of unrecognized, misplaced endotracheal tubes inserted by paramedics in a large urban, decentralized emergency medical services (EMS) system. METHODS: We conducted a prospective, observational study of patients intubated in the field by paramedics before emergency department arrival. During an 8-month period, emergency physicians assessed tube position at ED arrival using a combination of auscultation, end-tidal carbon dioxide (ETCO(2)) monitoring, and direct laryngoscopy...

STUDY OBJECTIVE: We evaluate the association between out-of-hospital use of continuous end-tidal carbon dioxide (ETCO2) monitoring and unrecognized misplaced intubations within a regional emergency medical services (EMS) system. METHODS: This was a prospective, observational study, conducted during a 10-month period, on all patients arriving at a regional Level I trauma center emergency department who underwent out-of-hospital endotracheal intubation. The regional EMS system that serves the trauma service area is composed of multiple countywide systems containing numerous EMS agencies...

Capnography continues to be an important tool in measuring expired carbon dioxide (CO2). Most recent Advanced Cardiac Life Support (ACLS) guidelines now recommend using capnography to ascertain the effectiveness of chest compressions and duration of cardiopulmonary resuscitation (CPR). Based on an extensive review of available published literature, we selected all available peer-reviewed research investigations and case reports. Available evidence suggests that there is significant correlation between partial pressure of end-tidal CO2 (PETCO2) and cardiac output that can indicate the return of spontaneous circulation (ROSC)...

BACKGROUND: Waveform capnography is considered the gold standard for verification of proper endotracheal tube placement, but current guidelines caution that it is unreliable in low-perfusion states such as cardiac arrest. Recent case reports found that long-deceased cadavers can produce capnographic waveforms. The purpose of this study was to determine the predictive value of waveform capnography for endotracheal tube placement verification and detection of misplacement using a cadaveric experimental model...

Crystalline d-tubocurarine has been isolated in good yield from curare prepared from a single plant species, namely, Chondodendron tomentosum. This result establishes with certainty the botanical origin of this compound and substantiates the supposition that it is this species which furnishes the active constituent in certain types of curare. The extract from this plant furthermore yielded two new tertiary alkaloids which could be converted into physiologically active quaternary bases. Methylation of the phenolic hydroxyl groups in the quaternary bases resulted in a 3-9-fold increase in physiological potency...

BACKGROUND: Hypoxemia and hypotension are common complications during endotracheal intubation of critically ill adults. Verbal performance of a written, preintubation checklist may prevent these complications. We compared a written, verbally performed, preintubation checklist with usual care regarding lowest arterial oxygen saturation or lowest systolic BP experienced by critically ill adults undergoing endotracheal intubation. METHODS: A multicenter trial in which 262 adults undergoing endotracheal intubation were randomized to a written, verbally performed, preintubation checklist (checklist) or no preintubation checklist (usual care)...

IMPORTANCE: It is unclear whether advanced airway management such as endotracheal intubation or use of supraglottic airway devices in the prehospital setting improves outcomes following out-of-hospital cardiac arrest (OHCA) compared with conventional bag-valve-mask ventilation. OBJECTIVE: To test the hypothesis that prehospital advanced airway management is associated with favorable outcome after adult OHCA. DESIGN, SETTING, AND PARTICIPANTS: Prospective, nationwide, population-based study (All-Japan Utstein Registry) involving 649,654 consecutive adult patients in Japan who had an OHCA and in whom resuscitation was attempted by emergency responders with subsequent transport to medical institutions from January 2005 through December 2010...

PURPOSE: Optimal out-of-hospital cardiac arrest (OHCA) airway management strategies are still controversial. Recent studies reported survival was higher among patients who received bag-valve-mask (BVM) than those receiving endotracheal intubation (ETI) or supraglottic airway (SGA). The aim of this study was to compare neurologically favorable survival outcomes among adult nontraumatic OHCA patients by prehospital airway. METHODS: We used the Korean nationwide OHCA cohort database from 2010 to 2013...

Both the American Society of Anesthesiologists and the UK NAP4 project recommend that an unspecified pre-operative airway assessment be made. However, the choice of assessment is ultimately at the discretion of the individual anaesthesiologist. We retrieved a cohort of 188 064 cases from the Danish Anaesthesia Database, and investigated the diagnostic accuracy of the anaesthesiologists' predictions of difficult tracheal intubation and difficult mask ventilation. Of 3391 difficult intubations, 3154 (93%) were unanticipated...

OBJECTIVES: Desaturation leading to hypoxemia may occur during rapid sequence intubation (RSI). Apneic oxygenation (AO) was developed to prevent the occurrence of oxygen desaturation during the apnea period. The purpose of this study was to determine if the application of AO increases the average lowest oxygen saturation during RSI when compared to usual care (UC) in the emergency setting. METHODS: A randomized controlled trial was conducted at an academic, urban, Level I trauma center...
