Emergency Department Airway Management Responsibilities in the United States

Educational Effects of Simulation and Non-Simulation Training in Airway Management according to Levels of the Kirkpatrick Model: A Systematic Review and Network Meta-Analysis

There is insufficient validation of the effectiveness of simulation-based training (Sim) or non-simulation-based training (non-Sim) for teaching airway management to healthcare professionals within the literature. We thus conducted a network meta-analysis comparing the effectiveness of Sim, non-Sim, and no educational intervention (NI) for airway management. The primary endpoints were knowledge scores (KnS) and behavioral performance scores (BpS) corresponding to assessments at levels 2 and 3 of the Kirkpatrick model, respectively. Effect sizes were expressed as standardized mean differences (Std. MD) and 95% credible intervals (CrIs). Regarding KnS, the educational effects of Sim and non-Sim were significantly improved compared to those of NI (Std. MD [95% CI]: 1.110 [0.903–1.316] and 0.819 [0.209–1.429], respectively); there was no significant difference between Sim and non-Sim. The educational effect of Sim in BpS was significantly improved compared to that of non-Sim and NI (0.850 [0.015–1.691] and 0.660 [0.241–1.076]); there were no differences between non-Sim and NI. Surface under the cumulative rank curve values demonstrated that Sim ranked highest in efficacy for KnS and BpS. This study provides valuable information regarding the educational efficacy of Sim and non-Sim in airway management. Larger randomized controlled trials are needed to confirm these findings.

Tracheal Intubation in Emergency Departments in China: A National Cross-Sectional Survey

Background

Tracheal intubation is a necessary but risky procedure performed in emergency departments (EDs) around the world. Relatively high morbidity has been encountered in Chinese EDs, which has raised concerns about peri-intubation ED management. This study aimed to investigate intubation procedures and identify any areas for improvement in Chinese EDs.

Methods

This was a questionnaire-based survey lasting 1 month (March 2021) in 41 tertiary-care hospital EDs in mainland China. The primary outcome was complications associated with intubation. Secondary outcomes were the first-pass success rate and blood pressure variations during intubation. Univariate and binary logistic regression analyses were used to find possible risk factors for first-pass intubation failure.

Results

In total, 1,020 replies were analyzed out of 1,080 surveys submitted (94.4% response rate). Most patients were elderly men with severe medical conditions like cardiac arrest (24.8%). In total, 97.2% of patients were given preoxygenation, and 48.1% received some form of pretreatment. Induction drugs (e.g., etomidate and ketamine) were less often used: 39.9% of intubations used sedatives, 5.5% used analgesics, and only 5.3% used muscle relaxants. The overall first-pass intubation success rate was 85.7% and was accompanied by a 19.8% adverse event rate. A marked decrease in blood pressure after intubation was also identified.

Conclusion

This survey found an 85.7% tracheal intubation first-pass success rate (which is relatively high compared to other countries) and a 19.8% adverse event rate (which is also relatively high). Given the very low rate of using induction medications (5.3% used muscle relaxants), future education should focus on induction drugs and traditional intubation techniques.

[In-hospital emergency care in the Federal Republic of Germany. A site survey of hospitals in the German Resuscitation Registry]

BACKGROUND

In contrast to prehospital care there is a lack of specifications for the organization and equipment of medical emergency teams for in-hospital emergency care.

OBJECTIVE

Evaluation of the organization, team composition, training, equipment and tasks of medical emergency teams in the Federal Republic of Germany.

MATERIAL AND METHODS

Evaluation of a web-based survey of all hospitals participating in the German Resuscitation Register between February and March2020. The participants were asked about team composition; emergency equipment; type, content and scope of special training or further training as well as other additional tasks in the everyday clinical routine when participating in the medical emergency team. Hospitals with ≤ or >600 beds were compared.

RESULTS

A total of 21 (>600 beds: 10, 48%; ≤600 beds: 11, 52%) hospitals participated in the survey. Team composition requirements were present at 76% (n = 16; ≤600 beds: 8, 72% vs. >600 beds: 8, 80%), training requirements for medical emergency teams at 38% (n = 16; ≤600 beds: 4, 36% vs. >600 beds: 4, 40%) of hospitals, with a focus on cardiac life support (n = 6, 28%; ≤600 beds: 3, 27% vs. >600 beds: 3, 30%) and airway management (n = 4, 19%; ≤600 beds: 3, 27% vs. >600 beds: 1, 10%). A 12-lead electrocardiogram (n = 7, 33%; ≤600 beds: 1, 9% vs. >600 beds: 6, 60%; p = 0.02), video laryngoscope (n = 7, 33%; ≤600 beds: 2, 18% vs. >600 beds: 5, 50%), ventilator without (n = 7, 33%; ≤600 beds: 2, 18% vs. >600 beds: 5, 50%) or with the possibility of non-invasive ventilation was part of the standard equipment in n = 4, 19% (≤600 beds: 1, 9% vs. >600 beds: 3, 30%). A total of 85% (n = 18; ≤600 beds: 10, 100% vs. >600 beds 8, 72%), had additional tasks in the daily clinical routine. While clinics with >600 beds staffed medical emergency teams 100% of the time from the intensive care units, in clinics ≤600 beds medical emergency teams were deployed significantly more often in the emergency department (n = 5, 45%) and in the normal wards (n = 5, 45%, p = 0.03).

CONCLUSION

Training and equipment of medical emergency teams in the Federal Republic of Germany is heterogeneous. They should at least meet the standards commonly used in prehospital emergency medicine and include the availability of a portable 12-lead electrocardiogram, a ventilator with the possibility of noninvasive ventilation and a video laryngoscope. Regardless of the size of the hospital, continuous availability of all members of the medical emergency teams should be ensured.

Emergency Airway Management Outside the Operating Room: Current Evidence and Management Strategies

Emergency airway management outside the operating room (OR) is often associated with an increased risk of airway related, as well as cardiopulmonary, complications which can impact morbidity and mortality. These emergent airways may take place in the intensive care unit (ICU), where patients are critically ill with minimal physiological reserve, or other areas of the hospital where advanced equipment and personnel are often unavailable. As such, emergency airway management outside the OR requires expertise at manipulation of not only the anatomically difficult airway but also the physiologically and situationally difficult airway. Adequate preparation and appropriate use of airway management techniques are important to prevent complications. Judicious utilization of pre- and apneic oxygenation is important as is the choice of medications to facilitate intubation in this at-risk population. Recent study in critically ill patients has shown that postintubation hemodynamic and respiratory compromise is common, independently associated with poor outcomes and can be impacted by the choice of drugs and techniques used. In addition to adequately preparing for a physiologically difficult airway, enhancing the ability to predict an anatomically difficult airway is essential in reducing complication rates. The use of artificial intelligence in the identification of difficult airways has shown promising results and could be of significant advantage in uncooperative patients as well as those with a questionable airway examination. Incorporating this technology and understanding the physiological, anatomical, and logistical challenges may help providers better prepare for managing such precarious airways and lead to successful outcomes. This review discusses the various challenges associated with airway management outside the OR, provides guidance on appropriate preparation, airway management skills, medication use, and highlights the role of a coordinated multidisciplinary approach to out-of-OR airway management.
