The Impact of Nighttime on First Pass Success During the Emergent Endotracheal Intubation of Critically Ill Patients

Analysis of Statistics Utilized in Primary Articles in the Journal of Intensive Care Medicine: A Prelude to Practical Pedagogy in Biostatistics

BackgroundBiostatistics is an increasing focus in current medical school curricula. This study evaluated the statistical methods utilized in a high-impact factor medical Journal to develop a guide to those statistics that can be applied to facilitate the interpretation of data for practicing physicians, fellows, residents, and medical students.MethodsIn Part 1 of our tandem manuscripts, the 100 most recent primary articles from February 2021 to December 2021 were analyzed from the Journal of Intensive Care Medicine. The evaluation consisted of study temporality, study design, types of descriptor variables, and types of statistical tests.ResultsRetrospective studies were most common (75/100, 75%), followed by prospective studies (23/100, 23%). The most popular designs were cohort (82/100, 82%), followed by case series (9/100, 9%), randomized control trials (4/100, 4%), and case-control (3/100, 3%). The most commonly utilized descriptor variables were frequency and proportion (100/100, 100%), followed by median (74/100, 74%) and mean (71/100, 71%). The chi-square test was the most frequently used statistical test (59/100, 59%), while logistic regression (48/100, 48%), Mann-Whitney-U (46/100, 46%), and two-sample independent t-test (40/100, 40%) also were popular.ConclusionThis review revealed that retrospective and cohort studies were utilized most frequently. The chi-square test was used in the majority of studies, while logistic regression was also popular. This information can help determine areas in which supplemental training will be most beneficial to improve the understanding of statistical methods in medical journals by practicing physicians, fellows, residents, and medical students. As an outgrowth of this study, we have developed a practical guide to relevant statistical methods, serving as Part 2 of these tandem manuscripts.

[Indications and success rate of endotracheal emergency intubation in clinical acute and emergency medicine]

BACKGROUND

Securing the airway in the emergency department (ED) is a high-stakes procedure; however, the primary success and complication rate are largely unknown in Germany. The aim of this study was a retrospective analysis of prospectively collected resuscitation room data for endotracheal intubation (ETI) regarding indications, performance and complications.

METHOD

Between 1 January 2020 and 30 June 2023 all ETIs conducted in the ED (Kliniken Maria Hilf, Moenchengladbach, Germany) were analyzed following approval by the ethics committee (EK 23-369). Primary intubations performed by the anesthesiology department were excluded. The core medical team of the ED underwent a six-week training program including a two-week anesthesia rotation prior to performing ETI in the ED. There were standard operating procedures (SOP) for both rapid sequence induction (RSI) and airway exchange with a placed laryngeal tube (LT) utilizing video laryngoscopy (C-Mac, Storz), rocuronium for relaxation and primary intubation with an elastic bougie. The primary success rate, overall success rate and intubation-related complications were analyzed. Additionally, the factor of consultant ED staff and residents was evaluated with respect to the primary success rate.

RESULTS

During the study period 499 patients were intubated by the core ED team and 28 patients underwent airway exchange from LT to ETI. Primary success could be achieved in 489/499 (98.0%) ETI and in 25/28 (89.3%) LT exchange patients. Surgically achieved securing of the airway was carried out in 5/527 (0.9%) patients in a cannot intubate situation and 11/527 (2.2%) patients suffered cardiac arrest minutes after the ETI. The overall first pass success rate of endotracheal tube placement was 514/527 (97.4%). The comparison of the primary success of consultants (168/175; 96.0%) vs. residents 320/325 (98.5%) yielded no significant differences (p = 0.08).

CONCLUSION

In clinical acute and emergency medicine, a standardized approach utilizing video laryngoscopy and a bougie following a structured training concept, can achieve an above-average high primary success rate with simultaneous low severe complications in the high-risk collective of critically ill emergency patients in an intrahospital setting.

Fatigue among anaesthesiologists in Europe: Findings from a joint EBA/NASC survey

BACKGROUND

Anaesthesiologists deliver an increasing amount of patient care and often work long hours in operating theatres and intensive care units, with frequent on-calls and insufficient rest in between. In the long term, this will negatively influence mental and physical health and well being. As fatigue becomes more prevalent, this has predictable implications for patient safety and clinical effectiveness. 1.

OBJECTIVE

This study aimed to evaluate the prevalence, severity, causes and implications of work-related fatigue amongst specialist anaesthesiologists.

DESIGN

An online survey of specialist anaesthesiologists.

PARTICIPANTS

The survey was sent to anaesthesiologists in 42 European countries by electronic mail.

MAIN OUTCOME MEASURES

Responses from a 36-item online survey assessed work-related fatigue and its impact on anaesthesiologists in European countries.

RESULTS

Work-related fatigue was experienced in 91.6% of the 1508 respondents from 32 European countries. Fatigue was caused by their working patterns, clinical and nonclinical workloads, staffing issues and excessive work hours. Over 70% reported that work-related fatigue negatively impacted on their physical and mental health, emotional well being and safe commuting. Most respondents did not feel supported by their organisation to maintain good health and well being.

CONCLUSION

Work-related fatigue is a significant and widespread problem amongst anaesthesiologists. More education and increased awareness of fatigue and its adverse effects on patient safety, staff well being and physical and mental health are needed. Departments should ensure that their rotas and job plans comply with the European Working Time Directive (EWTD) and introduce a fatigue risk management system to mitigate the effects of fatigue.

Challenges and outcomes in airway management outside the operating room

PURPOSE OF REVIEW

Airway management outside the operating room poses unique challenges that every clinician should recognize. These include anatomic, physiologic, and logistic challenges, each of which can contribute to complications and lead to poor outcomes. Recognizing these challenges and highlighting known outcome data may better prepare the team, making this otherwise daunting procedure safer and potentially improving patient outcomes.

RECENT FINDINGS

Newer intubating techniques and devices have made navigating anatomic airway challenges easier. However, physiological challenges during emergency airway management remain a cause of poor patient outcomes. Hemodynamic collapse has been identified as the most common peri-intubation adverse event and a leading cause of morbidity and mortality associated with the procedure.

SUMMARY

Emergency airway management outside the operating room remains a high-risk procedure, associated with poor outcomes. Pre-intubation hemodynamic optimization may mitigate some of the risks, and future research should focus on identification of best strategies for hemodynamic optimization prior to and during this procedure.

Implementation and Outcomes of a Difficult Airway Code Team Composed of Anesthesiologists in a Korean Tertiary Hospital: A Retrospective Analysis of a Prospective Registry

BACKGROUND

In 2017, we established an airway call (AC) team composed of anesthesiologists to improve emergency airway management outside the operating room. In this retrospective analysis of prospectively collected data from the airway registry, we describe the characteristics of patients attended to and practices by the AC team during the first 4 years of implementation.

METHODS

All AC team activations in which an airway intervention was performed by the AC team between June 2017 and May 2021 were analyzed.

RESULTS

In all, 359 events were analyzed. Activation was more common outside of working hours (62.1%) and from the intensive care unit (85.0%); 36.2% of AC activations were due to known or anticipated difficult airway, most commonly because of acquired airway anomalies (n = 49), followed by airway edema or bleeding (n = 32) and very young age (≤ 1 years; n = 30). In 71.3% of the cases, successful intubation was performed by the AC team at the first attempt. However, three or more attempts were performed in 33 cases. The most common device used for successful intubation was the videolaryngoscope (59.7%). Tracheal intubation by the AC team failed in nine patients, who then required surgical airway insertion by otolaryngologists. However, there were no airway-related deaths.

CONCLUSIONS

When coupled with appropriate assistance from an otolaryngologist AC system, an AC team composed of anesthesiologists could be an efficient way to provide safe airway management outside the operating room.
