Abstract
The description of the main scientifically consolidated innovations in recent years on Rapid Sequence Induction have been the subject of this narrative review. Data sources were PubMed, EMBASE, Web of Science, the Cochrane Central Register of Controlled Trials, and ClinicaTrials.gov, searched up to March 21st, 2023; rapid sequence induction and anesthesia were used as key word for the research. In recent years at least three significant innovations which have improved the procedure: firstly the possibility of using drugs which rapidly reverse the action of the myorelaxants and which have made it possible to give up the use of succinylcholine, replaced by rocuronium; secondly, the possibility of using much more effective pre-oxygenation methods than in the past, also through apneic oxygenation techniques which allow longer apnea time, and finally new monitoring systems much more effective than pulse oximetry in identifying and predicting periprocedural hypoxemia and indicating the need for ventilation in patients at risk of hypoxemia and preventing it. The description of three main scientifically consolidated innovations in recent years, in pharmacology, oxygen method of administration and monitoring, have been the subject of this narrative review.

Abstract
BACKGROUND Compared to other intravenous anesthetics, availability of a specific antagonist flumazenil is a clear advantage of remimazolam. We report a patient who could be rapidly woken up when laryngoscopy and tracheal intubation were unexpectedly difficult. CASE PRESENTATION A 62-year-old man was scheduled to have resection of a small gingival tumor. Preoperative airway examination was unremarkable except for an omega-shaped epiglottis. Anesthesia was induced with remifentanil/remimazolam infusion and rocuronium. A small omega-shaped edematous epiglottis precluded identification of glottis. Consciousness and spontaneous ventilation were rapidly restored after administration of flumazenil and sugammadex. Tracheostomy was done under local anesthesia while the patient breathed spontaneously. CONCLUSIONS Remimazolam can be a reasonable induction agent when there are concerns regarding airway management. Avoiding repeated airway manipulations is extremely important to prevent deterioration into a "cannot intubate, cannot ventilate (CICV)" emergency.

J Anaesthesiol Clin Pharmacol 2023; 39:482-487. [PMID: 38025560 PMCID: PMC10661644 DOI: 10.4103/joacp.joacp_534_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2021] [Revised: 07/03/2022] [Accepted: 08/14/2022] [Indexed: 12/01/2023] Open
Abstract
Background and Aims Intravenous induction agents like propofol and etomidate change the airway mechanics and thus influence mask ventilation. These changes have an impact on the administration of muscle relaxant in a difficult mask ventilation scenario. The difference in dynamics of airway after administration of two different intravenous agents has been assessed in this study. Material and Methods After formal registry in clinical trials, patients undergoing general anesthesia were recruited and randomized into group P and E. Patients were induced with either of the intravenous agents, and mask ventilation was performed with a ventilator. After 60 s, rocuronium was administered and ventilation continued. Measurements of tidal volume, peak airway pressure, and compliance were taken from the anesthesia ventilator at different time points - induction, relaxant, and intubation. Results There was no statistically significant difference between the two groups with respect to demographics, airway parameters, and airway mechanics, as measured by tidal volume, peak airway pressure, and lung compliance. There was an improvement in the tidal volume and compliance following induction with propofol, with a P value of 0.007 and 0.032, respectively, obtained in within-group comparison. Conclusion Propofol and etomidate were comparable in airway mechanics, but compliance and tidal volumes improved with propofol, which facilitated face mask ventilation.

There is no evidence that carbon dioxide-enriched oxygen before apnea affects the time to arterial desaturation, but it might improve cerebral oxygenation in anesthetized obese patients: a single-blinded randomized crossover trial. BMC Anesthesiol 2023; 23:41. [PMID: 36747148 PMCID: PMC9900199 DOI: 10.1186/s12871-023-01982-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 01/09/2023] [Indexed: 02/08/2023] Open
Abstract
PURPOSE Carbon dioxide (CO2) increases cerebral perfusion. The effect of CO2 on apnea tolerance, such as after anesthesia induction, is unknown. This study aimed to assess if cerebral apnea tolerance can be improved in obese patients under general anesthesia when comparing O2/Air (95%O2) to O2/CO2 (95%O2/5%CO2). METHODS In this single-center, single-blinded, randomized crossover trial, 30 patients 18-65 years, with body mass index > 35 kg/m2, requiring general anesthesia for bariatric surgery, underwent two apneas that were preceded by ventilation with either O2/Air or O2/CO2 in random order. After anesthesia induction, intubation, and ventilation with O2/Air or O2/CO2 for 10 min, apnea was performed until the cerebral tissue oxygenation index (TOI) dropped by a relative 20% from baseline (primary endpoint) or oxygen saturation (SpO2) reached 80% (safety abortion criterion). The intervention was then repeated with the second substance. RESULTS The safety criterion was reached in all patients before cerebral TOI decreased by 20%. The time until SpO2 dropped to 80% was similar in the two groups (+ 6 s with O2/CO2, 95%CI -7 to 19 s, p = 0.37). Cerebral TOI and PaO2 were higher after O2/CO2 (+ 1.5%; 95%CI: from 0.3 to 2.6; p = 0.02 and + 0.6 kPa; 95%CI: 0.1 to 1.1; p = 0.02). CONCLUSION O2/CO2 improves cerebral TOI and PaO2 in anesthetized bariatric patients. Better apnea tolerance could not be confirmed.

Abstract
Sugammadex may be required or used in multiple emergency situations. Moderate and high doses of this compound can be used inside and outside the operating room setting. In this communication, recent developments in the use of sugammadex for the immediate reversal of rocuronium-induced neuromuscular blockade were assessed. In emergency surgery and other clinical situations necessitating rapid sequence intubation, the tendency to use rocuronium followed by sugammadex instead of succinylcholine has been increasing. In other emergency situations such as anaphylactic shock caused by rocuronium or if intubation or ventilation is not possible, priority should be given to resuming ventilation maintaining hemodynamic stability, in accordance with the traditional guidelines. If necessary for the purpose of resuming ventilation, reversal of neuromuscular blockade should be done in a timely fashion.

Abstract
PURPOSE The dosing, potential adverse effects, and clinical outcomes of the most commonly utilized pharmacologic agents for rapid sequence intubation (RSI) are reviewed for the practicing emergency medicine pharmacist (EMP). SUMMARY RSI is the process of establishing a safe, functional respiratory system in patients unable to effectively breathe on their own. Various medications are chosen to sedate and even paralyze the patient to facilitate an efficient endotracheal intubation. The mechanism of action and pharmacokinetic/pharmacodynamic profiles of these agents were described in a 2011 review. Since then, the role of the EMP as well as the published evidence regarding RSI agents, including dosing, adverse effects, and clinical outcomes, has grown. It is necessary for the practicing EMP to update previous practice patterns in order to continue to provide optimal patient care. CONCLUSION While the agents used in RSI have changed little, knowledge regarding optimal dosing, appropriate patient selection, and possible adverse effects continues to be gained. The EMP is a key member of the bedside care team and uniquely positioned to communicate this evolving data.

Abstract
Sugammadex has been used for more than ten years in Australia and New Zealand and has been implicated as an effective treatment, and in some cases a potential cause, of a critical incident. We aimed to identify and analyse critical incidents involving sugammadex reported to webAIRS, a de-identified voluntary online critical incident reporting system in Australia and New Zealand. We identified 116 incidents where the reporter implicated sugammadex as either a cause (23 cases) or a treatment (93 cases) during anaesthesia. There were 17 incidents suggestive of sugammadex anaphylaxis, although not all were confirmed by skin testing. There were six incidents when bradycardia was temporally related to sugammadex administration, although it was not possible to exclude other causes or contributory factors. There were nine incidents in which sugammadex was used to reverse aminosteroid-related neuromuscular blockade successfully in a 'can't intubate, can't oxygenate' (CICO) situation, and a further 67 incidents in which sugammadex was used to reverse aminosteroid neuromuscular blockade as part of the management of other critical incidents. While sugammadex was used during the management of 16 cases of anaphylaxis, there was no clear indication that this altered the course of the anaphylaxis in any of the cases. These reports indicate that sugammadex can be a potential trigger for anaphylaxis and that its use may be associated with the development of significant bradycardia. However, it is not possible to estimate or even speculate on the incidence of these sugammadex-related incidents on the basis of voluntary reporting to a database such as webAIRS. The reports also indicate that sugammadex has been used successfully to reverse residual or deep aminosteroid neuromuscular blockade in critical incident situations and to help rescue CICO scenarios. These findings provide further support for ensuring the ready availability of sugammadex wherever aminosteroid muscle relaxants are used.

Abstract
BACKGROUND There is a worldwide consensus among experts that guidelines and algorithms on airway management contribute to improved patient safety in anesthesia. The present study aimed to determine the current practice of airway management of German anesthesiologists and assess the safety gap, defined as the difference between observed and recommended practice, amongst these practitioners. OBJECTIVE To determine the effect of implementing the guidelines on airway management practice in Germany amongst anesthesiologists and identify potential safety gaps. METHODS A survey was conducted in September 2019 by contacting all registered members of the German Society of Anaesthesiology and Intensive Care Medicine (DGAI) via email. The participants were asked about their personal and institutional background, adherence to recommendations of the current German S1 guidelines and availability of airway devices. RESULTS A total of 1862 DGAI members completed the questionnaire (response rate 17%). The main outcome was that anesthesiologists mostly adhered to the guidelines, yet certain recommendations, particularly pertaining to specifics of preoxygenation and training, showed a safety gap. More than 90% of participants had a video laryngoscope and half had performed more than 25 awake intubations using a flexible endoscope; however, only 81% had a video laryngoscope with a hyperangulated blade. An estimated 16% of all intubations were performed with a video laryngoscope, and 1 in 4 participants had performed awake intubation with it. Nearly all participants had cared for patients with suspected difficult airways. Half of the participants had already faced a "cannot intubate, cannot oxygenate" (CICO) situation and one in five had to perform an emergency front of neck access (eFONA) at least once. In this case, almost two thirds used puncture-based techniques and one third scalpel-based techniques. CONCLUSION Current practice of airway management showed overall adherence to the current German guidelines on airway management, yet certain areas need to be improved.

Planning and implementing safe management of the patient with an anticipated difficult airway. Can J Anaesth 2021; 68:1405-1436.

Abstract
PURPOSE Since the last Canadian Airway Focus Group (CAFG) guidelines were published in 2013, the published airway management literature has expanded substantially. The CAFG therefore re-convened to examine this literature and update practice recommendations. This second of two articles addresses airway evaluation, decision-making, and safe implementation of an airway management strategy when difficulty is anticipated. SOURCE Canadian Airway Focus Group members, including anesthesia, emergency medicine, and critical care physicians were assigned topics to search. Searches were run in the Medline, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL databases. Results were presented to the group and discussed during video conferences every two weeks from April 2018 to July 2020. These CAFG recommendations are based on the best available published evidence. Where high-quality evidence is lacking, statements are based on group consensus. FINDINGS AND KEY RECOMMENDATIONS Prior to airway management, a documented strategy should be formulated for every patient, based on airway evaluation. Bedside examination should seek predictors of difficulty with face-mask ventilation (FMV), tracheal intubation using video- or direct laryngoscopy (VL or DL), supraglottic airway use, as well as emergency front of neck airway access. Patient physiology and contextual issues should also be assessed. Predicted difficulty should prompt careful decision-making on how most safely to proceed with airway management. Awake tracheal intubation may provide an extra margin of safety when impossible VL or DL is predicted, when difficulty is predicted with more than one mode of airway management (e.g., tracheal intubation and FMV), or when predicted difficulty coincides with significant physiologic or contextual issues. If managing the patient after the induction of general anesthesia despite predicted difficulty, team briefing should include triggers for moving from one technique to the next, expert assistance should be sourced, and required equipment should be present. Unanticipated difficulty with airway management can always occur, so the airway manager should have a strategy for difficulty occurring in every patient, and the institution must make difficult airway equipment readily available. Tracheal extubation of the at-risk patient must also be carefully planned, including assessment of the patient's tolerance for withdrawal of airway support and whether re-intubation might be difficult.

Abstract
Management of the unanticipated difficult airway is one of the most relevant and challenging crisis management scenarios encountered in clinical anesthesia practice. Several guidelines and approaches have been developed to assist clinicians in navigating this high-acuity scenario. In the most serious cases, the clinician may encounter a failed airway that results from failure to ventilate an anesthetized patient via facemask or supraglottic airway or intubate the patient with an endotracheal tube. This dreaded cannot intubate, cannot oxygenate situation necessitates emergency invasive access. This article reviews the incidence, management, and complications of the failed airway and training issues related to its management.

Abstract
BACKGROUND Sugammadex is a medication newly available to many emergency physicians. It effectively, and within minutes, reverses neuromuscular blockade in patients who have received rocuronium or vecuronium. The role of sugammadex for the reversal of neuromuscular blockade after rapid sequence intubation in the emergency department (ED) is evolving, and limited emergency medicine-specific literature exists. OBJECTIVE This narrative review evaluates the role of sugammadex for the reversal of neuromuscular blockade in the ED. DISCUSSION The basic pharmacology, duration of action, adverse effects, and important medication and disease interactions specific to sugammadex are well described. Case reports suggest sugammadex can reverse neuromuscular blockade to facilitate an urgent, neurologic examination by an emergency physician or consultant. Multiple case reports of failure to improve airway patency with the use of sugammadex, even when neuromuscular blockade is completely reversed, and concern for added difficulty of definitive airway management in a patient with spontaneous movement suggest that sugammadex should largely be omitted from failed or difficult airway management strategies. Instead, it is important to focus on the ability to oxygenate and ventilate, including progression to surgical airway or jet ventilation if needed. CONCLUSION Sugammadex is an effective, rapid reversal agent for rocuronium and has the potential use to facilitate an urgent neurologic examination shortly after administration of rocuronium. Its routine inclusion in a failed or difficult emergency airway is not supported by available literature.

Abstract
Sugammadex reverses neuromuscular blockade by the steroidal nondepolarizing neuromuscular blocking agents rocuronium and vecuronium. In 2015, it was approved in the United States by the Food and Drug Administration for adult use. However, there are ongoing clinical trials investigating its use in the pediatric population. Before approval in adult use in the United States, several adverse effects were noted to occur in patients receiving sugammadex in clinical trials including prolonged QT interval, bradycardia, hypersensitivity reactions, and prolongation of coagulation parameters. Additional investigations further elucidated the risks of these adverse events. Sugammadex is approved for use in children older than 2 years in other countries in Europe and Asia. Investigations suggest that the efficacy, safety, and pharmacokinetic profile is similar in children when compared with adults. Published pediatric data favor the use of sugammadex in children older than 2 years, but there are some data in young children younger than 2 years. Case reports discuss the use of sugammadex in pediatric patients with neuromuscular diseases. Although sugammadex is typically used in the operating room for reversing neuromuscular blockade for surgical procedures, there is a small but important role for sugammadex use in the emergency department. In cases where rapid neurological examination is required after neuromuscular blockage with rocuronium or vecuronium, sugammadex can assist in facilitating a timely comprehensive neurological examination where pharmacologic or surgical management may depend on examination findings such as in the case of cerebral vascular accident, status epilepticus, or traumatic brain injury. Some clinicians have advocated for the use of sugammadex in the cannot intubate, cannot ventilate scenario. However, caution should be exercised in this situation as reversal of paralysis can take up to 22 minutes to occur.

Abstract
Neuromuscular blocking agents (NMBAs) can be an effective modality to address challenges that arise daily in the intensive care unit (ICU). These medications are often used to optimize mechanical ventilation, facilitate endotracheal intubation, stop overt shivering during therapeutic hypothermia following cardiac arrest, and may have a role in the management of life-threatening conditions such as elevated intracranial pressure and status asthmaticus (when deep sedation fails or is not tolerated). However, current NMBA use has decreased during the last decade due to concerns of potential adverse effects such as venous thrombosis, patient awareness during paralysis, development of critical illness myopathy, autonomic interactions, and even residual paralysis following cessation of NMBA use. It is therefore essential for clinicians to be familiar with evidence-based practices regarding appropriate NMBA use in order to select appropriate indications for their use and avoid complications. We believe that selecting the right NMBA, administering concomitant sedation and analgesic therapy, and using appropriate monitoring techniques mitigate these risks for critically ill patients. Therefore, we review the indications of NMBA use in the critical care setting and discuss the most appropriate use of NMBAs in the intensive care setting based on their structure, mechanism of action, side effects, and recognized clinical indications. Lastly, we highlight the available pharmacologic antagonists, strategies for sedation, newer neuromuscular monitoring techniques, and potential complications related to the use of NMBAs in the ICU setting.

Abstract
Sugammadex is a novel pharmacologic agent, which reverses neuromuscular blockade with a mechanism that differs from acetylcholinesterase inhibitors such as neostigmine. There is a growing body of literature demonstrating its efficacy in pediatric patients of all ages. Prospective trials have demonstrated a more rapid and more complete reversal of rocuronium-induced neuromuscular blockade than the acetylcholinesterase inhibitor, neostigmine. Unlike the acetylcholinesterase inhibitors, sugammadex effectively reverses intense or complete neuromuscular blockade. It may also be effective in situations where reversal of neuromuscular blockade is problematic including patients with neuromyopathic conditions or when acetylcholinesterase inhibitors are contraindicated. This article reviews the physiology of neuromuscular transmission as well as the published literature, regarding the use of sugammadex in pediatric population including the pediatric intensive care unit population. Clinical applications are reviewed, adverse effects are discussed, and dosing algorithms are presented.

Abstract
RATIONALE AND AIMS Sugammadex is a novel neuromuscular blockade reversal agent which rapidly reverses the effects of rocuronium and vecuronium. Compared with the first-generation neuromuscular blockade reversal agent, neostigmine, sugammadex has a number of superior properties; however, sugammadex is significantly more expensive per dose compared with neostigmine (~CAD$95 vs $4). Given the high cost of sugammadex, many Ontario hospitals either do not stock the drug or have specific policies on when the drug can be administered. This study was designed to determine access to sugammadex in Ontario hospitals, as well as the prevalence and content of institutional policies on its use. METHODS We designed a survey assessing the availability of sugammadex and institutional policies on its use. We identified 60 Ontario hospitals with surgical services and obtained contact information for 45 of the anaesthesia departments. Surveys were sent to each department chief, and results were collected from July to October 2018. RESULTS Thirty-four (75.6%) hospitals responded to the survey. Twenty-seven (79.4%) of the 34 respondent hospitals had sugammadex. Of the seven hospitals that did not have sugammadex, six were group B hospitals, and one was a paediatric hospital. Of the 27 hospitals with sugammadex, 16 (59.3%) hospitals had specific policies on when sugammadex may be used. Based on policies, sugammadex was most frequently allowed to be used in emergency situations, especially failed intubations or "can't intubate, can't ventilate" situations where 100% of policies allowed its use. Policies on specific patient populations for sugammadex use were uncommon, with 43.8% of existing hospital policies not specifying any patient populations. CONCLUSIONS Though most hospitals have sugammadex available, there is a marked heterogeneity in hospital policies on its use. Given the high cost of sugammadex use, it is worthwhile to have evidence-based policies on its use. Judicious use of sugammadex may also have secondary cost-saving benefits, through improved operating room efficiency and decreased complication rates.

Abstract
Sugammadex is a reversal agent that was engineered to reverse the effects of aminosteroid muscle relaxants. It is a modified gamma-cyclodextrin, i.e. a large glucose molecule bound in a ring-like structure. Sugammadex, when injected intravenously, creates a concentration gradient favoring the movement of aminosteroid muscle relaxants from the neuromuscular junction back into the plasma, and then encapsulates the aminosteroid muscle relaxants within its inner structure by forming tight water-soluble complexes. The dissociation of the aminosteroidal muscle relaxant from the post-synaptic acetylcholine receptors is responsible for the termination of neuromuscular blockade. This review article presents the current indication, mechanism of action, limitations, side effects and contraindications of sugammadex. An overview of monitoring of the adequacy of reversal of aminosteroid muscle relaxants with sugammadex is presented. Moreover, the use of sugammadex in special situations, including “cannot intubate cannot oxygenate” scenarios is also described.

Abstract
BACKGROUND Onset times and conditions for intubation after rocuronium versus suxamethonium at cesarean section have been evaluated, but no study thus far has examined the influence of these neuromuscular blocking drugs on the surgical conditions or their effect on the duration of surgery and the ease of fetal delivery. We aimed to compare the surgical conditions for delivery in parturients who received deep neuromuscular block with rocuronium with those who had induction with suxamethonium. METHODS Ninety patients undergoing cesarean section under general anesthesia were randomized to receive either rocuronium 0.6 mg/kg or suxamethonium 1 mg/kg for tracheal intubation and delivery. Times to delivery and the quality of surgical conditions, using a five-point Surgical Rating Scale for Delivery (SRSD) ranging from 1 (poor) to 5 (excellent), were evaluated. RESULTS The median SRSD (range) was found to be significantly better in the rocuronium group [4 (3-5) points vs 3 (2-4) points with suxamethonium (P <0.001)]. Whereas the mean (SD) induction-to-intubation interval was longer with rocuronium [106 (34) s vs 68 (32) s with suxamethonium (95% CI of the difference 24 to 52 s, P <0.001)], the incision-to-delivery interval was shorter in the rocuronium group [147 (68) s vs 196 (51) s with suxamethonium (95% CI of the difference -75 to -24 s, P <0.001)]. The mean induction-to-delivery intervals were similar [268 (73) s vs 276 (63) s, respectively]. CONCLUSIONS Whereas the induction-to-delivery intervals were comparable, we found rocuronium superior to suxamethonium in allowing better surgical conditions for fetal delivery, which enabled an easier delivery and a shorter incision-to-delivery interval.

Abstract
This fourth and last installment of my history of basic airway management discusses the current (i.e., "modern") era of anesthesia and resuscitation, from 1960 to the present. These years were notable for the implementation of intermittent positive pressure ventilation inside and outside the operating room. Basic airway management in cardiopulmonary resuscitation (i.e., expired air ventilation) was de-emphasized, as the "A-B-C" (airway-breathing-circulation) protocol was replaced with the "C-A-B" (circulation-airway-breathing) intervention sequence. Basic airway management in the operating room (i.e., face-mask ventilation) lost its predominant position to advanced airway management, as balanced anesthesia replaced inhalation anesthesia. The one-hand, generic face-mask ventilation technique was inherited from the progressive era. In the new context of providing intermittent positive pressure ventilation, the generic technique generated an underpowered grip with a less effective seal and an unspecified airway maneuver. The significant advancement that had been made in understanding the pathophysiology of upper airway obstruction was thus poorly translated into practice. In contrast to consistent progress in advanced airway management, progress in basic airway techniques and devices stagnated.

Abstract
Surgery for laryngeal cancer and the following recurrent tumor growth may further change the anatomy of the airway. Airway management during anesthesia induction is challenging for the patients undergoing secondary surgery due to recurrence of laryngeal cancer or its postoperative complication, but it has never been reported. In this report, we described three cases of anesthetic induction which had different process of airway events. The first case was given intravenous general anesthetic for induction and experienced failed intubation, difficult mask ventilation and emergent tracheostomy, eventually were rescued successfully. The second case presented a fixed metastatic mass about 6 cm diameter upon the primary surgical scar of incision and preoperative apnea, underwent fibroscopy-guided conscious intubation and the process was uneventful. The third case had erythema and swelling under the mandible with erupted ulcer as well as neck immobility due to recurrent tumor. The anesthesiologist attempted fibroscopy-guided intubation via nasal passage with a tracheal tube in 2.8 mm diameter but it was failed. Subsequently, tracheostomy was performed under bilateral superficial cervical plexus block and the dissected larynx by operation verified distorted structure of glottis with S-shaped stenosis. This report concludes that, during the anesthetic induction for this special type of surgery, a detailed and comprehensive evaluation of the airway, and a routine fibroscopic examination are especially important.

Abstract
These guidelines describe a comprehensive strategy to optimize oxygenation, airway management, and tracheal intubation in critically ill patients, in all hospital locations. They are a direct response to the 4th National Audit Project of the Royal College of Anaesthetists and Difficult Airway Society, which highlighted deficient management of these extremely vulnerable patients leading to major complications and avoidable deaths. They are founded on robust evidence where available, supplemented by expert consensus opinion where it is not. These guidelines recognize that improved outcomes of emergency airway management require closer attention to human factors, rather than simply introduction of new devices or improved technical proficiency. They stress the role of the airway team, a shared mental model, planning, and communication throughout airway management. The primacy of oxygenation including pre- and peroxygenation is emphasized. A modified rapid sequence approach is recommended. Optimal management is presented in an algorithm that combines Plans B and C, incorporating elements of the Vortex approach. To avoid delays and task fixation, the importance of limiting procedural attempts, promptly recognizing failure, and transitioning to the next algorithm step are emphasized. The guidelines recommend early use of a videolaryngoscope, with a screen visible to all, and second generation supraglottic airways for airway rescue. Recommendations for emergency front of neck airway are for a scalpel-bougie-tube technique while acknowledging the value of other techniques performed by trained experts. As most critical care airway catastrophes occur after intubation, from dislodged or blocked tubes, essential methods to avoid these complications are also emphasized.
