Abstract Background Pre-hospital emergency airway management plays an important role in pre-hospital care. Laryngeal masks are increasingly employed for the airway management of pre-hospital critical patients and have achieved promising results. Although several randomized controlled trials have reported benefits, the efficacy of laryngeal masks in pre-hospital emergency airway management compared to endotracheal intubation have not been systematically reviewed.Methods Electronic databases (PubMed, Cochrane Library, Embase, Scopus and CNKI) were searched up to April 2019 for related randomized studies. Outcome indicators were overall intubation success rates, success rates of the initial intubation, insertion time, ventilation efficiency rates, SpO2 rise time and blood gas index. Two investigators selected the trials, extracted the data according to inclusion and exclusion criteria, and assessed the quality of the literature according to the Jada score. The meta-analysis was performed using stata14.0 software.Results We included 9 randomized manikin studies and 31 human studies. Meta-analysis of the manikin studies showed that the overall intubation success rates of the laryngeal mask group [RR=1.10, 95% CI (1.02, 1.18), P<0.05] and the success rates of first intubation [RR=1.25, 95% CI (1.01, 1.55), P <0.05] were significantly higher than the endotracheal intubation group. The insertion time of the laryngeal mask group was also significantly shorter [SMD = -1.53, 95% CI (-1.88, -1.17), P <0.05]. In human studies, excluding the success rates of first intubation and insertion time, the laryngeal mask was superior to endotracheal intubation and improved the patients’ blood gas index and shortened the SpO2 rise time. All the results were statistically significant.Conclusions Compared to endotracheal intubation, laryngeal masks could quickly and effectively improve patient ventilation in pre-hospital emergencies, highlighting its utility for clinical application .

Abstract Background : Pre-hospital emergency airway management plays an important role in pre-hospital care. Laryngeal masks are increasingly employed for the airway management of pre-hospital critical patients and have achieved promising results. Although several randomized controlled trials have reported benefits, the efficacy of laryngeal masks in pre-hospital emergency airway management compared to endotracheal intubation have not been systematically reviewed.

Two investigators selected the trials, extracted the data according to inclusion and exclusion criteria, and assessed the quality of the literature according to the Jada score. The meta-analysis was performed using stata14.0 software. Results: We included 31 human studies. Compared to endotracheal intubation, the application of laryngeal mask for pre-hospital emergencies enhanced the ventilation efficiency rates [RR=1.20, 95% CI (1.06, 1.35), P<0.001], improved the success of first intubation [RR=1.29, 95% CI (1.18, 1.40), P<0.001] and the patients’ blood gas index, shortened the insertion and SpO2 rise times [SMD=-3.48, 95% CI (-4.17, -2.80), P < 0.001; -2.19, 95% CI (-3.06, -1.32), P < 0.001] and reduced the incidence of adverse events [RR=0.41, 95% CI (0.30, 0.57, P<0.001]. All results were stable and statistically significant. Conclusions: Laryngeal masks could quickly and effectively improve patient ventilation in pre-hospital emergencies, highlighting its utility for clinical application.

Objectives Airway management during anaesthesia in cats is always a demanding task and is associated with several complications. The aim of this study was to evaluate the practicability and complications during feline-specific laryngeal mask placement in anaesthetised cats as an alternative to endotracheal intubation. Methods In this prospective clinical study, laryngeal masks were placed in 148 anaesthetised cats. Success of placement was evaluated by capnography. Results Placement was possible at the first attempt in 136 cats, at the second attempt in eight cats and at the third attempt in one cat. In one cat, placement was not possible. Two cats were excluded. Failure to position the laryngeal mask at the first attempt was not different between laryngeal mask sizes ( P = 0.313) or positioning during placement ( P = 0.406). In nine cats, the laryngeal mask dislocated during the procedure. Dislocation occurred more often in the dorsal position than in the sternal ( P = 0.018) and right lateral positions ( P = 0.046). Mucous obstruction of the laryngeal mask occurred in one of these cats and regurgitation in another. Material-related issues, such as disconnection of the parts of the laryngeal mask and leakage of the balloon, were observed in 2/8 laryngeal masks. Conclusions and relevance The placement of a feline-specific laryngeal mask was easy to perform. In about 7% of the cases, replacement of the device was required due to mispositioning or dislocation. Full monitoring, including capnography, should be provided to uncover dislocation and airway obstruction immediately.

Abstract Purpose Tracheal tube introducers and stylets remain some of the most widely used devices for aiding practitioners in performing endotracheal intubation (ETI). The purpose of this systematic review is to evaluate the efficacy of tracheal tube introducers and stylets for ETI in the prehospital setting. Methods A literature search was conducted on the 2nd of March 2021 across PubMed, Embase (Ovid) and the Cochrane Central Register of Controlled Trials (CENTRAL) to identify relevant studies. Included studies had their data extracted and both a quality assessment and statistical analysis were performed. Results The summary estimate of prehospital studies with video technology showed a statistically significant increase in first pass ETI success in favour of bougies (RR 1.15, CI 1.10–1.21, p < 0.0001). The summary estimates of prehospital studies without video technology and simulation studies with and without video technology showed no statistical difference between methods for first pass or overall ETI success. Some of the highest success rates were recorded by devices that incorporated video technology. Stylets lead to a shorter time to ETI while bougies were easier to use. Neither device was associated with a higher rate of ETI complications than the other. Conclusion Both tracheal tube introducers and stylets function as efficacious aids to intubation in the prehospital environment. Where video technology is available, bougies could offer a statistically significant advantage in terms of first pass ETI success. Where video technology is unavailable, a combination of clinical scenario, practitioner expertise and personal preference might ultimately guide the choice of device.

Facemask Ventilation

This review examines the airway adjuncts currently used to acutely manage the neonatal airway. It describes the challenges encountered with facemask ventilation and intubation. Evidence is presented on how to optimise intubation safety and success rates with the use of videolaryngoscopy and attention to the intubation environment. The supraglottic airway (laryngeal mask airway) is emerging as a promising neonatal airway adjunct. It can be used effectively with little training to provide a viable alternative to facemask ventilation and intubation in neonatal resuscitation and be used as an alternative conduit for the administration of surfactant.

Core Skill

Pediatric endotracheal intubation is a procedure that can be stress provoking to the emergency physician. Although the need for this core skill is rare, when confronted with this situation, the emergency physician must have knowledge of the anatomic, physiologic, and pathologic components unique to the pediatric airway to optimize success. Furthermore, the emergency physician should be well versed in the various equipment and adjuncts as well as techniques developed to effectively manage the pediatric airway. This review covers the pathophysiology and practice of endotracheal intubation. Figures show a gum elastic bougie; the Mallampati classification; appropriate oropharyngeal, laryngeal, and tracheal axes; advancing the laryngoscope to lift the epiglottis; endotracheal tube position in neonates; and synchronized intermittent mandatory ventilation pressure-regulated volume control mechanical ventilation. Tables list endotracheal tube sizes, neonatal endotracheal tube sizes, pediatric laryngeal mask airway sizes, commonly used induction agents, and endotracheal tube insertion depth guidelines. This review contains 6 figures, 8 tables, and 77 references.
