Airway management is a controversial topic in modern Emergency Medical Services (EMS) systems. Among many concerns regarding endotracheal intubation (ETI), unrecognized esophageal intubation and observations of unfavorable neurologic outcomes in some studies raise the question of whether alternative airway techniques should be first-line in EMS airway management protocols. Supraglottic airway devices (SADs) are simpler to use, provide reliable oxygenation and ventilation, and may thus be an alternative first-line airway device for paramedics. In 2019, Alachua County Fire Rescue (ACFR; Alachua, Florida USA) introduced a novel protocol for advanced airway management emphasizing first-line use of a second-generation SAD (i-gel) for patients requiring medication-facilitated airway management (referred to as “rapid sequence airway” [RSA] protocol).
Study Objective:
This was a one-year quality assurance review of care provided under the RSA protocol looking at compliance and first-pass success rate of first-line SAD use.
Methods:
Records were obtained from the agency’s electronic medical record (EMR), searching for the use of the RSA protocol, advanced airway devices, or either ketamine or rocuronium. If available, hospital follow-up data regarding patient condition and emergency department (ED) airway exchange were obtained.
Results:
During the first year, 33 advanced airway attempts were made under the protocol by 23 paramedics. Overall, compliance with the airway device sequence as specified in the protocol was 72.7%. When ETI was non-compliantly used as first-line airway device, the first-pass success rate was 44.4% compared to 87.5% with adherence to first-line SAD use. All prehospital SADs were exchanged in the ED in a delayed fashion and almost exclusively per physician preference alone. In no case was the SAD exchanged for suspected dislodgement evidenced by lack of capnography.
Conclusion:
First-line use of a SAD was associated with a high first-pass attempt success rate in a real-life cohort of prehospital advanced airway encounters. No SAD required emergent exchange upon hospital arrival.
Pre-hospital airway management is an essential skill for every pre-hospital clinician and should be performed to the same standards as would be expected in the emergency department. This chapter recommends tailored pre-hospital airway management in terms of clinical care delivered to the patient, skills of the clinician and the infrastructure of emergency medical system to achieve this. The importance of having a standardised, well-rehearsed approach, using aids to reduce cognitive load, articulating a clear airway management plan and having a structured way of handling airway management difficulties is highlighted. The concept of the physiologically difficult airway is discussed and the significance of excellent pre-oxygenation, peroxygenation, first-pass success and post-intubation care is discussed. Backup equipment in the form of second generation supraglottic airway devices, a videolaryngoscope with both standard and hyperangulated blades and equipment for an emergency front of neck airway should be available when advanced pre-hospital airway management is provided. When delivering airway management to trauma patients, an awareness of potential anatomical difficulties combined with careful management of physiological derangement is necessary to deliver safe, high quality care.
Supraglottic airways (SGAs) have been part of core anaesthetic practice for approximately 30 years, since the introduction of the classic laryngeal mask which is described in some detail. In many countries an SGA is now used for airway management for the majority of anaesthetics. Optimal use and insertion technique are described. The range of SGAs available and their roles have expanded dramatically in this time. Second generation SGAs are those designed to reduce the risk of aspiration and are emphasised in this chapter. With the wide range of SGAs available it can be problematic to decide which device to use and this is especially so as the boundaries of acceptable use are ever widened. This chapter describes those devices with the greatest versatility and utility – arguably also with the greatest safety profile too – and some newer devices. SGAs have a major role to play in advanced and difficult airway management. The use of an SGA as a rescue device and as a conduit for intubation during management of the difficult airway is described in detail.
