INTRODUCTION: Drowning results in more than 360,000 deaths annually, making it the 3rd leading cause of unintentional injury death worldwide. Prior studies have examined airway interventions affecting patient outcomes in cardiac arrest, but less is known about drowning patients in arrest. This study evaluated the outcomes of drowning patients in the Cardiac Arrest Registry to Enhance Survival (CARES) who received advanced airway management. METHODS: A retrospective analysis of the CARES database identified cases of drowning etiology between 2013 and 2018...

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) studies have focused on the benefits and harms of placing an intra-arrest advanced airway, but few studies have evaluated the benefits and harms after successful placement. We hypothesize that increased time in the tumultuous prehospital environment after intra-arrest advanced airway placement results in reduced patient survival. METHODS: This was a secondary analysis of adult, non-traumatic, OHCA patients with an advanced airway placed in the PRIMED trial...

BACKGROUND: Current guidelines for cardiopulmonary resuscitation (CPR) recommend that standard dose of epinephrine be administered every 3 to 5 minutes during cardiac arrest. However, there is controversy about the association between timing of epinephrine administration and outcomes after out-of-hospital cardiac arrest (OHCA). This study aimed to determine whether the timing of intravenous epinephrine administration is associated with outcomes after OHCA. METHODS: We analyzed Japanese government-led nationwide population-based registry data for OHCA...

BACKGROUND AND PURPOSE: We aimed to determine whether the care process and outcomes in patients with acute stroke who received recanalization therapy changed during the outbreak of coronavirus disease 2019 (COVID-19) in South Korea. METHODS: We used data from a prospective multicenter reperfusion therapy registry to compare the care process-including the time from symptom onset to treatment, number of treated patients, and discharge disposition-and treatment outcomes between before and during the COVID-19 outbreak in South Korea...

INTRODUCTION: The positive impact of advances in military medicine and the influence these have had on civilian medical practice have been well documented throughout history: this review will be looking specifically between 2009 and 2020. AIMS: Review of innovations that have been implemented or have influenced civilian practice within the areas of trauma, disease outbreak management and civilian systems between 2009 and 2020. This review will also aim to explore the impact that working with or within the military can have on individuals within civilian healthcare systems and the future challenges we face to maintain skills...

BACKGROUND: High-density lipoproteins (HDLs), particles characterized by their reverse cholesterol transport function, display pleiotropic properties, including anti-inflammatory and antioxidant functions. Moreover, all lipoproteins (HDLs but also low-density lipoproteins (LDLs)) neutralize lipopolysaccharides, leading to increased bacterial clearance. These two lipoproteins decrease during sepsis, and an association between low lipoprotein levels and poor outcome was reported. The goals of this study were to characterize the lipid profile of septic patients hospitalized in our intensive care unit (ICU) and to determine the relationship with the outcome...

Shortness of breath is a common complaint among patients in emergency medicine. While most common causes are usually promptly identified, less frequent aetiologies might be challenging to diagnose, especially in the pre-hospital setting. We report a case of prehospital dyspnoea initially ascribed to pulmonary oedema which turned out to be the result of profound metformin-associated metabolic acidosis. This diagnosis was already made during the prehospital phase by virtue of arterial blood gas measurement. Pre-hospital measurement of arterial blood gases is therefore feasible and can improve diagnostic accuracy in the field, thus avoiding unnecessary delay and potential harm to the patient before initiating the appropriate therapeutic actions...

OBJECTIVE: Emergency medical service (EMS) transportation after acute stroke is associated with shorter symptom-to-arrival times and more rapid medical attention when compared to patient transportation by private vehicle. METHODS: We analyzed data from the Paul Coverdell National Acute Stroke Program from 2014 to 2019 among stroke (ischemic and hemorrhagic) and transient ischemic attack (TIA) patients to examine patterns in EMS utilization. RESULTS: Of 500,829 stroke and TIA patients (mean age 70...

BACKGROUND: Protocols for expediting critical trauma patients directly from the helipad to the operating room tend to vary by center, rely heavily on physician gestalt, and lack supporting evidence. We evaluated a population of severely injured trauma patients with the aim of determining objective factors associated with the need for immediate surgical intervention. METHODS: All highest-activation trauma patients transported by air ambulance between 1/1/16 and 12/31/17 were enrolled retrospectively...

BACKGROUND: Prehospital care is potentially hazardous with the possibility for patients to experience an adverse event. However, as compared to secondary care, little is known about how patient safety is managed in prehospital care settings. Therefore, the aims of this systematic review were to: identify and classify the methods of measuring and monitoring patient safety that have been used in prehospital care using the five dimensions of the Measuring and Monitoring Safety framework; and use this classification to identify where there are safety "blind spots" and make recommendations for how these deficits could be addressed...

Limb trauma is a frequent pathology in pre-hospital care. The first responder caregiver plays a crucial role in terms of the application of the initial care in order to save the limb and life of the patient and to limit the functional consequences. He has to follow strict rules of safety and efficiency. The quality of his initial assessment will guide him towards the most appropriate care and the appropriate chronology.

OBJECTIVE: The present study describes the utility of a forehead continuous deep temperature monitoring system by the staff members of a doctor helicopter (DH). METHODS: A questionnaire survey was performed for all flight doctors who had used this system during transportation by the DH to assess its merits and demerits. RESULTS: The major benefits of this system were its easy usability, disposable nature, low labor cost, continuous demonstration of the deep temperature in a prehospital setting, and low invasiveness...

Medical transport teams often handle cases of complex, critically ill patients and are in need of rapid, bedside assessments to guide clinical decision making. The use of point-of-care ultrasound (POCUS) as a diagnostic indicator has gained increased acceptance in emergency medicine. Ultrasound devices have become increasingly portable, and numerous studies have demonstrated that use in the prehospital setting is feasible, accurate, and can have a dramatic impact on the care of patients. In this case report, we highlight the use of handheld ultrasound in the identification of right heart dilation in an unstable patient with respiratory failure in a rural emergency department, concerning for massive pulmonary embolism...

OBJECTIVE: Patients with life- or limb-threatening severe injuries pose a challenge to prehospital services. Time-critical decision making and treatment are challenging because of occasional incomplete information, limited resources, adverse environments, and a range of basic and advanced technical skills available. To prepare for these infrequent critical situations, medical personnel from the helicopter emergency medical service at Oslo University Hospital developed a 1-day advanced trauma training course focusing on individual skills and teamwork during resuscitative procedures...

OBJECTIVE: Videolaryngoscopy (VL) in the prehospital setting remains controversial, with conflicting data on its utility. We compared C-MAC VL (Karl Storz, Tuttlingen, Germany) versus direct laryngoscopy (DL) in the prehospital setting, recording the grade of the glottic view, first pass success (FPS), overall success, and equipment functionality. METHODS: We conducted a prospective observational study with a convenience sample of 49 adult patients who were intubated by flight crew nurses and paramedics using the C-MAC videolaryngoscope from April to November 2013...

OBJECTIVE: Hypothermia secondary to environmental exposure is a serious condition. Active external warming measures to treat it may prove challenging in the prehospital setting. We conducted an experimental study to measure the ability of commercially available heating elements to warm intravenous (IV) fluids during infusion. METHODS: 250-milliliter bags of dextrose 10% solution were suspended inside a refrigerator. IV tubing was coiled, and the tubing output was placed inside a thermally insulated cup...

OBJECTIVE: Ketamine for rapid sequence intubation (RSI) is typically dosed at 1 to 2 mg/kg intravenously. The need to ensure dissociation during RSI led some to administer ketamine at doses greater than 2 mg/kg. This study assessed associations between ketamine dose and adverse events. METHODS: This multisite, retrospective study included adult subjects undergoing RSI with intravenous ketamine. Subjects were categorized into 2 groups: a standard ketamine dose (≤ 2 mg/kg intravenously) or a high dose (> 2 mg/kg intravenously)...

OBJECTIVE: Helicopter emergency medical services play an important role in the prehospital care of critically ill and injured patients, providing enhanced interventions and direct transfer to specialist centers. Essex & Herts Air Ambulance (EHAAT) delivers prehospital critical care to patients in Essex, Hertfordshire, and the surrounding areas. Historically, EHAAT's resources have not operated during the night. This study aimed to ascertain demand for prehospital critical care in Essex and Hertfordshire during night hours...
