critically ill patients who may die quickly. The complications of tracheal intubation in an emergency are multifactorial and have a direct impact on the patient's prognosis. The type of pathology leading to airway protection, oxygenation, hemodynamic status of the patient, difficult anatomic parameters of the airway, type of intubation sequence, different operator training, and human factors have been associated with complications and poor outcomes.<a class="elsevierStyleCrossRefs" href="#bib0005"><span class="elsevierStyleSup">1–6</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">The more intubation attempts that are made in an emergency, the more often adverse effects and complications occur,<a class="elsevierStyleCrossRefs" href="#bib0035"><span class="elsevierStyleSup">7–9</span></a> so the greatest effort should be made to ensure that the first attempt is the best intubation attempt.</p><p id="par0015" class="elsevierStylePara elsevierViewall">Nowadays, the main reference for FPS rate in emergencies ED is 84% in high-income countries.<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">10,11</span></a> Our study group has recently published an observational study of 241 patients in which that rate was 78%.<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">12</span></a></p><p id="par0020" class="elsevierStylePara elsevierViewall">A quasi-experimental prospective before-after study is presented.

This study was conducted during the first waves (pre-intervention) and second waves (post-intervention) of the COVID-19 pandemic, a time when biosafety protocols were modified for the care of patients with advanced respiratory disease. To improve a 15% intubation success rate on the first attempt with 90% power and an alpha of 0.05, 79 patients were included in each phase.

It consisted of four pillars: theoretical teaching, practical exercises on individual and team skills, cognitive aids, and a pre-intubation checklist. The last two pillars were presented on posters that were pasted on the walls so that they could be easily seen in the resuscitation rooms (see supplementary material in the Appendix). Ear and sternal alignment, use of the bougie during the first intubation attempt, proper traction and handling of the laryngoscope, appropriate use of the endotracheal tube and insertion of the bougie, and external manipulation of the larynx were recommended during intervention training. Mannequin models of intubations and rescue devices (laryngeal mask and cricothyrotomy) were used for the practical exercises. Strictly followed the safety protocols recommended by health authorities for practical sessions. The number of participants per session was limited to ensure social distancing, and personal protective equipment (PPE) was used. The main authors of the article conducted training sessions with theoretical activities and practical instructions. They focused on the main points to improve the FPS rate and emphasized the importance of optimizing the oxygenation and hemodynamic resuscitation of the patient before intubation when immediate airway management is not required. Cognitive aids in the resuscitation room and the use of pre-intubation checklists were introduced. Both emergency physicians, emergency residents, and rotating residents received the training. The emergency department only had a direct Macintosh laryngoscope available, which was used for all intubations.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0130">Main interest variables</span><p id="par0045" class="elsevierStylePara elsevierViewall">Several variables were included in the registry, such as the operator experience, the number of intubation attempts, intubation judgment, predictors of a difficult airway, Cormack score, assist devices, complications, blood pressure, heart rate, and pulse oximetry before and after intubation.</p><p id="par0050" class="elsevierStylePara elsevierViewall">We define an intubation attempt as the insertion of a laryngoscope into a patient's mouth, even if the endotracheal tube does not pass.

Measures of central trends and dispersion were calculated for the quantitative variables.

The percentage of FPS (85.3%; IC95%: 78.20–90.48) achieved in this second phase was similar to the previously informed in a systematic review and meta-analysis.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a></p><p id="par0135" class="elsevierStylePara elsevierViewall">The improvement in FPS in this study is even more relevant when we consider three potential drawbacks. First, a high number of intubations were performed by residents who were relatively inexperienced in airway management (junior residents) in the post-intervention period compared with the baseline period. Second, in the post-intervention period, there was a higher proportion of patients who were intubated due to severe COVID -19 pneumonia, which may pose a greater challenge to airway management from a pathophysiologic perspective (if oxygen saturation is above 90% but drops rapidly, the intubator could stop the procedure and attempt to restore oxygenation, which could affect the outcome of the variable FPS.<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">13</span></a> Finally, all intubations were performed with direct laryngoscopy, a device that has lower FPS rates compared with the use of a videolaryngoscope in ED.<a class="elsevierStyleCrossRefs" href="#bib0070"><span class="elsevierStyleSup">14–17</span></a> Although videolaryngoscopy has been shown not only to improve glottic visualization but also to reduce the number of failed attempts, it is still not available in all emergency departments. Therefore, a simple intervention similar to the one presented in our study may be considered helpful in EDs in low-to-moderate resource countries where this expensive technology is not readily available.</p></span><span id="sec0070" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0165">Study interpretation</span><p id="par0140" class="elsevierStylePara elsevierViewall">Study data may be interpreted as supporting that the intervention performed was the key to improve the FPS percentage and thus reducing the risks associated with the procedure, other than hypoxemia. These results correlate with other similar publications. Corl et al. found a 16.2% improvement in a successful posterior intubation compared with the use of the modified Montpelier protocol. At the same time, they found a 12.6% decrease in complications.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">18</span></a> In a study conducted in three intensive care units, Jaber et al. also succeeded in reducing the severe complications associated with tracheal intubation by up to 13% after following an intervention protocol (intubation care bundle management).<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">19</span></a></p><p id="par0145" class="elsevierStylePara elsevierViewall">In a recent study conducted by Nauka et al.,<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">20</span></a> a higher rate of successful endotracheal intubations was found during the pandemic. The authors attribute this improvement to the significant increase in the use of neuromuscular blocking agents and video laryngoscopy during the pandemic. Similarly, Leeies et al.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">21</span></a> found higher rates of successful endotracheal intubations when comparing pre- and post-pandemic stages. The authors concluded that the modifications made to the intubation processes in response to the COVID-19 pandemic do not appear to be associated with worse outcomes compared to pre-COVID-19 practices.</p><p id="par0150" class="elsevierStylePara elsevierViewall">In addition to training, the introduction of cognitive tools and checklists on the walls of the resuscitation room was a significant factor in the results of this study. Although pre-intubation checklists have been shown to reduce complications such as hypoxemia, they have not been shown to reduce mortality yet. However, they can be helpful tools to optimize teamwork and effective communication. It also ensures that elements are immediately available when needed.<a class="elsevierStyleCrossRefs" href="#bib0110"><span class="elsevierStyleSup">22,23</span></a></p><p id="par0155" class="elsevierStylePara elsevierViewall">In the post-intervention period, changes were made to the procedure and medications used to demonstrate adherence to the intervention components. The choice of medications when performing intubations must be adapted to the pathophysiologic state of the patient.<a class="elsevierStyleCrossRef" href="#bib0120"><span class="elsevierStyleSup">24</span></a> Propofol, which tends to cause hypotension as its main side effect,<a class="elsevierStyleCrossRefs" href="#bib0125"><span class="elsevierStyleSup">25,26</span></a> was used less frequently and replaced by etomidate, which is more hemodynamically stable. Ketamine, usually recommended as a pre-intubation sedative to shock patients,<a class="elsevierStyleCrossRefs" href="#bib0120"><span class="elsevierStyleSup">24,27</span></a> was similarly administered on the first and second phases. The increased use of rocuronium in the post-intervention phase can be attributed to the fact that new drugs were added to the hospital's medical inventory during this period, as well as to the training in the use of this drug provided during the intervention phase. The low proportion of Cormack 3 in the post-intervention phase could also be interpreted as a result of the training, in which the correct laryngoscopic maneuver, adequate positioning of the patient, and manipulation of the external larynx during the procedure were particularly emphasized. The bougie, which has been associated with higher rates of FPS in emergencies,<a class="elsevierStyleCrossRef" href="#bib0140"><span class="elsevierStyleSup">28</span></a> became part of the recommendations made during the intervention phase, and it was more frequently used in the post-intervention phase. A recent multicenter study made by Drivers et al.<a class="elsevierStyleCrossRef" href="#bib0145"><span class="elsevierStyleSup">29</span></a> showed that the use of a bougie did not significantly increase the frequency of successful intubation on the first attempt compared with the use of a stylet endotracheal tube. Despite these results, we believe that in well-trained hands, the bougie is a critical tool for the first attempt at intubation.</p><p id="par0160" class="elsevierStylePara elsevierViewall">Contrary to expectations, obesity was not one of the factors associated with the number of intubation attempts. In other publications, this factor was mentioned as the main difficulty with a higher failure rate.<a class="elsevierStyleCrossRefs" href="#bib0150"><span class="elsevierStyleSup">30,31</span></a> This could be due to high compliance with ramp positioning or useful intubation aids such as the bougie,<a class="elsevierStyleCrossRef" href="#bib0160"><span class="elsevierStyleSup">32</span></a> the stylet,<a class="elsevierStyleCrossRef" href="#bib0165"><span class="elsevierStyleSup">33</span></a> or external laryngeal manipulation.<a class="elsevierStyleCrossRef" href="#bib0170"><span class="elsevierStyleSup">34</span></a> At least one of these strategies was used in 83 obese patients (89.24%).

This is also supported by the fact that pre-intubation oxygen saturation levels were different between the pre-intervention and post-intervention groups, with a median of 98% (IQR: 89.0−99.0) and 95% (IQR: 88.7−99.0), respectively.</p><p id="par0180" class="elsevierStylePara elsevierViewall">A recently published study by Cattin et al.,<a class="elsevierStyleCrossRef" href="#bib0190"><span class="elsevierStyleSup">38</span></a> conducted during the same period as our study, found a higher incidence of hypoxemia (43.5%) and hemodynamic instability (65%) compared with our study. We believe that the higher levels of hypoxemia may be due to the fact that all patients included in this study had a confirmed diagnosis COVID -19, whereas the higher proportion of hemodynamic instability may be due to the fact that the authors reported the use of midazolam as the induction agent of choice in most intubations and in 43.63% of cases in combination with propofol, both well known hypotensive drugs. A recent large multicenter study by Vincenzo et al. reported an incidence of hemodynamic instability of 42.6%, which was also higher than ours but with a lower incidence of hypoxemia (9.3%).</p><p id="par0185" class="elsevierStylePara elsevierViewall">It is important to highlight that in the post-intervention period, a higher number of intubations were performed in a shorter time frame. This increase may be attributed to the fact that more patients with severe pneumonia due to COVID -19 were admitted during this period. As a result, the daily intubation rate increased by 87.5% compared with the preintervention period, with the average number increasing from 0.8 intubations per day (123 intubations in 153 days) to 1.5 intubations per day (143 in 92 days) after the intervention.</p><p id="par0190" class="elsevierStylePara elsevierViewall">Interestingly, the lower incidence of cardiac arrest after intubation in the post-intervention phase (0.6%) was comparable to the study by Park & col.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a></p></span><span id="sec0075" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0170">Limitations</span><p id="par0195" class="elsevierStylePara elsevierViewall">Our study has several limitations. First, since it is a quasi-experimental one from a single institution, we can not draw definitive conclusions to prove causality. Second, it is possible that the observed effects were enhanced by the acquisition of more experience, as operators performed a greater number of intubations during the study, independent of the intervention itself. Third, the number of attempts was recorded but not the time spent on them. Fourth, the low percentage of FPS on the first phase of the study may have been influenced by changes in intubation care and operator fear of infection during the procedure.</p></span></span><span id="sec0080" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0175">Conclusion</span><p id="par0200" class="elsevierStylePara elsevierViewall">In our study, a low-cost and simple educational intervention was significantly associated with an improvement in FPS and achieved the same rate of FPS as in high-income countries.
