Objective

Rapid sequence intubation (RSI) is a critical skill commonly performed by air medical teams in the United States. To improve safety and reduce potential patient harm, checklists have been implemented by various institutions in intensive care units, emergency departments, and even prehospital air medical programs. However, the literature suggests that checklist use before RSI has not shown improvement in clinically important outcomes in the hospital. It is unclear if RSI checklist use by air medical crews in prehospital environments confers any clinically important benefit.

Methods

This institutional review board–approved project is a before-and-after observational study conducted within a large helicopter ambulance company. The RSI checklist was used by flight crewmembers (flight paramedic/nurse) for over 3 years. Data were evaluated for 8 quarters before and 8 quarters after checklist implementation, spanning December 2014 to March 2019. Data were collected, including the self-reported use of the checklist during intubation attempts, the reason for intubation, and correlation with difficult airway predictors (HEAVEN [Hypoxemia, Extremes of size, Anatomic disruption, Vomit, Exsanguination, Neck mobility/Neurologic injury] criteria), and compared with airway management before the implementation of the checklist. The primary outcome was improved first-pass success (FPS) when compared among those who received RSI before the checklist versus those who received RSI with the checklist. The secondary outcome was a definitive airway sans hypoxia improvement noted on the first pass among adult patients as measured before and after RSI checklist implementation. Post-RSI outcome scenarios were recorded to analyze and validate the effectiveness of the checklist.

Results

Ten thousand four hundred five intubations were attempted during the study. FPS was achieved in 90.9% of patients before RSI checklist implementation, and 93.3% achieved FPS postimplementation of the RSI checklist (P ≤ .001). In the preimplementation epoch, 36.2% of patients had no HEAVEN predictors versus 31.5% after RSI checklist implementation. These data showed that before RSI checklist implementation, airways were defined as less difficult than after implementation.

Conclusion

The implementation of a standardized RSI checklist provided a better identification of deterring factors, affording efficient and accurate actions promoting FPS. Our data suggest that when a difficult airway is identified, using the RSI checklist improves FPS, thereby reducing adverse events.

Objective

Accurate triage of children referred for tertiary pediatric critical care services is crucial to ensure optimal disposition and resource conservation. We aimed to explore the characteristics and level of care needs of children referred to tertiary pediatric critical care inpatient and transport services and the characteristics of referring physicians and hospitals to which these children present.

Methods

We conducted a 1-year retrospective cohort study of children (< 16 years) with documented referral to pediatric critical care and specialized transport services at a tertiary pediatric hospital from regional (24/7 pediatrician on-call coverage) and community (no pediatric specialty services) hospitals in Canada's Maritime provinces.

Results

We identified 205 documented referrals resulting in 183 (89%) transfers; 97 (53%) were admitted to the pediatric intensive care unit (PICU). Of 150 children transferred from centers with 24/7 pediatric specialist coverage, 45 (30%) were admitted to the tertiary hospital pediatric medical unit with no subsequent admission to the PICU. Of 20 children transferred from community hospitals and admitted to the tertiary hospital general pediatric medical unit, 9 (45%) bypassed proximate regional hospitals with specialist pediatric care capacity. The specialized pediatric critical care transport team performed 151 (83%) of 183 interfacility transfers; 83 (55%) were admitted to the PICU.

Conclusion

One third of the children accepted for interfacility transfer after pediatric critical care referral were triaged to a similar level of care as could be provided at the sending or nearest regional hospital. Improved utilization of pediatric expertise in regional hospitals may reduce unnecessary pediatric transports and conserve valuable health care resources.

Local anesthetic systemic toxicity (LAST) is a potentially life-threatening complication that may occur after local anesthetic injection. After reaching the systemic circulation, cardiovascular and central nervous system derangements may appear, with potentially fatal complications if left untreated. The pillars for LAST treatment are advanced life support measures, airway and seizure management, and a 20% lipid emulsion intravenous administration. When occurring in the prehospital setting, LAST is difficult to recognize, mostly because of its features overlapping with other acute conditions. Prompt treatment is also challenging because lipid emulsion may not be routinely carried on emergency vehicles. This article reports a case of LAST occurring in a dental ambulatory located in a remote location within the Italian Alps in which effective communication among different components of the same regional health care system (dispatch center, prehospital teams, and hospital network) led to fast lipid emulsion retrieval en route and on-site toxicity resolution. This case can inspire future operational changes, such as antidote networks available to prehospital emergency medicine crews, avoiding unnecessary deployment of antidotes on ambulances or helicopters, which is difficult to preserve without increasing management costs. However, to be established, such a network would need protocols to facilitate antidote retrieval, training focused on toxidromes recognition, and improved communication skills among different professionals involved in prehospital emergency medicine.

Objective

Advanced airway management, including the use of rapid sequence intubation (RSI), is fundamental in resuscitation. However, the reported experience with pediatric airway management is limited because of the relatively low number of emergency RSI procedures in children. The aim of this study was to document the experience with pediatric RSI in a large air medical database and explore opportunities for improvement.

Methods

All pediatric patients (age < 18 years) undergoing RSI by air medical crews between 2015 and 2019 were included in this analysis. Subjects were divided a priori into 3 age subgroups (0-2 years, 3-8 years, and 9-17 years). The primary variables of interest included overall intubation success, first-attempt intubation success, and first-attempt intubation success without desaturation. The rates of positive-pressure ventilation (PPV) use for preoxygenation and oxygen desaturation were also explored.

Results

A total of 1,091 pediatric RSI patients were included. The overall intubation success rate was 98% (0-2 years = 96%, 3-8 years = 97%, and 9-17 years = 98%), with 91% intubated on the first attempt (0-2 years = 86%, 3-8 years = 90%, and 9-17 years = 92%) and 87% intubated on the first attempt without oxygen desaturation (0-2 years = 80%, 3-8 years = 88%, and 9-17 years = 90%). A sharp decline in intubation success was observed with preoxygenation SpO₂ values < 97% across all patients. Younger patients (0-2 years) had lower initial SpO₂ values and decreased first-attempt success rates with and without desaturation. These patients were less likely to receive PPV during preoxygenation attempts and had lower use of video laryngoscopy or a bougie on the initial intubation attempt.

Conclusion

In this study, we documented high success rates for air medical pediatric RSI. Higher target SpO₂ values may be justified during preoxygenation. Intubation success, PPV use for preoxygenation, video laryngoscopy, and the use of a bougie were lower for younger patients.

Drawing from a comprehensive Japan-based literature review and the author's personal experience, this article presents findings that highlight potential improvements in clinical outcomes, such as reduced mortality rates, by optimizing the current resuscitation procedure for cardiopulmonary arrest. Many countries have adopted similar procedures for cardiopulmonary arrest. This article presents a prioritized resuscitation method based on scientific evidence, aiming to improve survival rates. The study, which was conducted in Japan, revealed inconsistencies in the current resuscitation procedure for cardiopulmonary arrest. The study did not involve direct participants but relied on literature review for data collection. A literature review was conducted to analyze the survival rates of various resuscitation methods. The interventions reviewed in the literature included cardiopulmonary resuscitation, automated external defibrillator, and automatic mechanical chest compressions. The survival rate of cardiopulmonary arrest in Japan was found to be low. The results of the literature review suggest that cardiopulmonary resuscitation or automatic mechanical chest compressions should be applied before using an automated external defibrillator. The study emphasizes the need to prioritize resuscitation methods with higher survival rates. This article presents a prioritized resuscitation method based on scientific evidence, aiming to improve survival rates. It is hoped that this new approach will lead to a significant improvement in the survival rates of cardiopulmonary arrest patients.

We present the case of a 10-year-old previously healthy male who suffered an out-of-hospital cardiac arrest because of abdominal trauma and survived with excellent neurologic outcomes and near complete return to baseline functional status at hospital discharge. The rapid response and efficient mobilization of resources led to an excellent patient outcome despite the severity of injuries, including intra-abdominal injuries with expected mortality, out-of-hospital traumatic arrest, coagulopathy, and an extended pediatric intensive care unit stay. This case underscores the significance of timely advanced trauma life support interventions, especially early blood product administration, efficient transport, and airway management, while sharing a remarkable case of out-of-hospital pediatric traumatic arrest with near full recovery.
