Airway management in children is usually very straightforward. Unfortunately, when it is not straightforward complications associated with problems encountered while managing the airway can be life-threatening. Airway management can be considered to consist of several different techniques for oxygenating and ventilating an anesthetized patient, namely mask ventilation, supraglottic airway device ventilation, and tracheal intubation. This chapter discusses these techniques and the factors associated with difficulty in performing them. There are anatomic features associated with difficulty in all of these techniques that are caused by syndromes or abnormal airway anatomy in children, although around 20% of difficult intubations are unanticipated. The majority of complications occur when attempting a difficult tracheal intubation. Morbidity and mortality relating to tracheal intubation correlate to the number of attempts at tracheal intubation. Severe hypoxia is estimated to occur in around 9% of children who are difficult to intubate and hypoxic cardiac arrest in nearly 2%, so the key to successful airway management is to focus on maintaining oxygenation and choosing a technique with the best chance of a successful outcome during the first attempt at airway management. This review contains 6 figures, 7 tables, and 41 references.  Keywords: cricothyrotomy, difficult airway, direct laryngoscopy, fiberoptic bronchoscopy, front of neck access, intubation, pediatric, videolaryngoscopy

Early insertion of a supraglottic airway (SGA) device could improve chest compression fraction by allowing providers to perform continuous chest compressions or by shortening the interruptions needed to deliver ventilations. SGA devices do not require the same expertise as endotracheal intubation. This study aimed to determine whether the immediate insertion of an i-gel® while providing continuous chest compressions with asynchronous ventilations could generate higher CCFs than the standard 30:2 approach using a face-mask in a simulation of out-of-hospital cardiac arrest. A multicentre, parallel, randomised, superiority, simulation study was carried out. The primary outcome was the difference in CCF during the first two minutes of resuscitation. Overall and per-cycle CCF quality of compressions and ventilations parameters were also compared. Among thirteen teams of two participants, the early insertion of an i-gel® resulted in higher CCFs during the first two minutes (89.0% vs. 83.6%, p = 0.001). Overall and per-cycle CCF were consistently higher in the i-gel® group, even after the 30:2 alternation had been resumed. In the i-gel® group, ventilation parameters were enhanced, but compressions were significantly shallower (4.6 cm vs. 5.2 cm, p = 0.007). This latter issue must be addressed before clinical trials can be considered.

Background: Recent recommendations made by ILCOR have de-emphasised the role of advanced airway management such as “endotracheal intubation” (ETI) during cardiac arrest in favour of maximising the number of chest compressions performed by rescuers. Maximising time available for compressions is achieved by minimising hands-off time (HOT). This has led to first responders and paramedics performing single rescuer CPR using a bag-valve-mask (BVM) device as opposed to the historical practice of intubating and ventilating via an endotracheal tube. Bag-valve-mask ventilations, especially during single rescuer CPR, are however associated with complications potentially resulting in increased ventilation times. More time spent on ventilations in the single rescuer scenario naturally leads to an increase in HOT and less time being available for compressions. It is postulated that the use of an appropriate supraglottic airway device (SAD) may decrease the time spent on the ventilation component of CPR and result in a decrease in HOT.Objectives: This pilot study evaluated how interruptions to chest compressions or hands-off time (HOT) are affected by the placement of an i-gel® airway vs. simple BVM ventilation during single rescuer CPR.Method: 16 participants performed two, ten-minute single rescuer CPR simulations, firstly using the BVM and later the i-gel® airway for ventilation. Data pertaining to ventilations and HOT in each scenario was statistically analysed and compared.Results: The i-gel® airway demonstrated a superior ease of ventilation compared to BVM alone and resulted in a reduction of time spent on ventilations overall. The i-gel® however took a mean of 29 s, ± 10 s, to secure which contributes considerably to HOT.Conclusion: The use of the i-gel® airway resulted in a considerable decrease in the amount of time spent on ventilations and in more compressions being performed. The overall reduction in HOT was, however, offset by the time it took to secure the device. Further investigation into the use and securing of the i-gel® airway in single rescuer CPR is recommended.

Implication Statement: Despite the increasing popularity of video laryngoscopes, the supraglottic airway device (SAD) remains a critical airway rescue tool. The SAD provides a conduit for tracheal intubation in failed laryngoscopy. This article aims to help the operator: (1) select an intubating SAD with consistent performance; (2) inform the appropriate SAD-endotracheal tube pairings; and (3) explain various SAD and endotracheal tube maneuvers available to increase chances of successful intubation. Objectives: The first supraglottic airway device (SAD) was introduced more than thirty years ago. Since then, SADs have undergone multiple iterations and improvements. The SAD remains an airway rescue device for ventilation and an intubation conduit on difficult airway algorithms. Data Sources: Several SADs are specifically designed to facilitate tracheal intubation, i.e., “intubating SADs,” while most are “non-intubating SADs.” The two most commonly reported tracheal intubation methods via the SADs are the blind and visualized passage of the endotracheal tube (ETT) preloaded on a fiberoptic scope. Fiberoptic guided tracheal intubation (FOI) via an intubating SAD generally has higher success rates than blind intubations and is thus preferred. However, fiberscopes might not always be readily available, and anesthesiologists should be skilled to successfully intubate blindly through a SAD. Summery: This narrative review describes intubating SAD with consistent performance, appropriate SAD-ETT pairings, and various SAD and ETT maneuvers to increase successful intubation chances.
