BACKGROUND AND OBJECTIVES: The appropriate use of blood components is essential for ethical use of a precious, donated product. The aim of this study was to report in-hospital red blood cell (RBC) transfusion after pre-hospital transfusion by helicopter emergency medical service paramedics. A secondary aim was to assess the potential for venous blood lactate to predict ongoing transfusion. MATERIALS AND METHODS: All patients who received RBC in air ambulance were transported to a single adult major trauma centre, had venous blood lactate measured on arrival and did not die before ability to transfuse RBC were included...

Pleural cavity drainage is a crucial component of the surgical management of patients with various chest diseases. Digital drainage systems are increasingly used in contemporary thoracic surgical procedure, which is likely a result of their effectiveness in achieving early postoperative ambulation, cutting down on hospital stays and lowering costs. The vast majority of thoracic surgeons worldwide prefer digital drainage systems to traditional ones. The advantages of the former, however, are disputed by some researchers...

BACKGROUND: Pre-Hospital Emergency Anaesthesia (PHEA) has undergone significant developments since its inception. However, optimal drug dosing remains a challenge for both medical and trauma patients. Many prehospital teams have adopted a drug regimen of 3 mcg/kg fentanyl, 2 mg/kg ketamine and 1 mg/kg rocuronium ('3:2:1'). At Essex and Herts Air Ambulance Trust (EHAAT) a new standard dosing regimen was introduced in August 2021: 1 mcg/kg fentanyl, 2 mg/kg ketamine and 2 mg/kg rocuronium (up to a maximum dose of 150 mg) ('1:2:2')...

INTRODUCTION: Falls in the community can have major impacts on patient lives. There can be long lasting physical and psychological consequences of a fall and subsequent long lie. The annual burden to ambulance services responding to falls at home is high. Affordable devices to help people get up from the floor, or reduce the risk of a long lie, would be useful and widely applicable. CASE REPORT: We present the case of 2 families who successfully used an air mattress and a bath lift to get the fallen person up off the floor following a fall, when they had previously called an ambulance...

A 23-year-old female with a history of idiopathic epilepsy was found to have a right chest cavity shadow in a school health checkup 5 years before. CT revealed a thin-walled cavity lesion in the right middle lobe containing a ball-like mass, showing air crescent sign. After falling due to a seizure, she was transported by ambulance and admitted. CT revealed diffuse ground-glass opacities throughout the right lung field. Bronchoscopy revealed bloody bronchial alveolar lavage fluid. Due to the tumor hemorrhage, an elective simple right middle lobe resection was performed without complications...

Objective: In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction. Methods: In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022...

BACKGROUND: Kiteboarding (kitesurfing on water and snowkiting) is a fairly new sport and is defined as a high-risk sport. The injury rate has been reported to be between 6 and 9 per 1000 h. The aim of the study was to identify and describe kiteboarding-related injuries in Norway over a five-year period. METHODS: We used "snowball sampling" to identify kiteboarding accidents in a retrospective study. In addition, we conducted structural searches in the National Air Ambulance Service and Search and Rescue Helicopter patient record databases...

Fixed Wing Air Ambulance providers routinely transport patients agitated from traumatic brain injury sequelae across long distances in a unique environment. The current paradigm limits options available to air medical clinicians to those routinely found on ground based, short distance vehicles, plus whatever a sending facility might be willing to provide. We postulate that dexmedetomidine offers a safe, effective alternative to improve patient care and enhance the safe operation of aircraft.

OBJECTIVE: Treating traumatic hemorrhage is time sensitive. Prehospital care and transport modes (eg, helicopter and ground) may influence in-hospital events. We hypothesized that prehospital time (on-scene time [OST] and total prehospital time [TPT]) and transport mode are associated with same-day transfusion and mortality. Furthermore, we sought to identify regions of anatomic injury that modify the relationship between prehospital time and outcomes in strata corresponding to transport types...

OBJECTIVE: Airway management is a cornerstone of helicopter air ambulance patient management. The purpose of this study was to evaluate the overall quality of airway management of critical care crews in 3 common locations for intubation. METHODS: This was a prospective observational simulation study assessing the overall airway management of critical care providers managing simulated patients in an emergency department, helicopter, and ambulance. Composite scores were obtained and compared with respect to physical environment and provider certification level...

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) in children is rare and can potentially result in severe neurological impairment. Our study aimed to identify characteristics of and factors associated with favourable neurological outcome following the resuscitation of children by the Swiss helicopter emergency medical service. MATERIALS AND METHODS: This retrospective observational study screened the Swiss Air-Ambulance electronic database from 01-01-2011 to 31-12-2021...

BACKGROUND: Critical hypertension in major trauma patients is associated with increased mortality. Prehospital emergency anaesthesia (PHEA) is performed for 10% of the most seriously injured patients. Optimising oxygenation, ventilation, and cerebral perfusion, whilst avoiding extreme haemodynamic fluctuations are the cornerstones of reducing secondary brain injury. The aim of this study was to report the differential determinants of post-PHEA critical hypertension in a large regional dataset of trauma patients across three Helicopter Emergency Medical Service (HEMS) organisations...

BACKGROUND AND AIMS: With advancements in imaging and microelectrode recording techniques, general anesthesia (GA) has emerged as an alternative option for Parkinson's disease (PD) patients undergoing subthalamic nucleus deep brain stimulation (STN-DBS). In this study, we compared the advantages and disadvantages of using GA and local anesthesia for STN-DBS in enhanced recovery after surgery (ERAS). METHODS: Surgical outcomes of STN-DBS were evaluated using the unified PD rating scales (UPDRS)...

BACKGROUND: Outcomes of trauma "walk-in" patients (using private vehicles or on foot) are understudied. We compared outcomes of ground ambulance vs walk-ins, hypothesizing that delayed resuscitation and uncoordinated care may worsen walk-in outcomes. METHODS: A retrospective analysis 2020 American College of Surgeons Trauma Quality Programs (ACS-TQP) databases compared outcomes between ambulance vs "walk-ins." The primary outcome was in-hospital mortality, excluding external facility transfers and air transports...

Mortality from stroke remains high in Australia, especially for patients located outside the metropolitan cities. This is because they have limited access to specialized stroke facilities for optimal stroke treatment. Mobile stroke units have the capability to take CT scanners out to the patient however current CT commercial scanner designs are large and heavy. As such, this paper aims to design and develop a lightweight CT scanner for use in a mobile stroke unit (either road-based or air-based ambulance) to bring healthcare solution to patients in the rural and remote areas...

BACKGROUND: Norway has a long coastline, steep mountains, and wide fjords, which presents some challenges to the prehospital emergency healthcare system. In recent years, the prehospital emergency medical services (EMS) have undergone significant changes, structurally, in terms of professionalisation of the services and in the education level of the personnel. In this article, we aim to describe the current structure for handling prehospital medical emergencies. METHODS: For healthcare, Norway is divided into four Regional Health Authorities, consisting of 19 Health Trusts, where 18 have an EMS...

BACKGROUND: In Europe, ambulances are increasingly being equipped with blood products for prehospital use. Available evidence on the early administration of blood products comes from military medicine and the Anglo-American medical literature; the evidence cannot be easily transferred to European countries. OBJECTIVES: This study assesses the incidence of patients with massive haemorrhage after trauma and the potential need for prehospital blood transfusions. METHODS: Data reported by 37 German air rescue stations between 2015 and 2020 were retrospectively analysed to predict the need for massive transfusion...

OBJECTIVE: Limited data exists for optimal blood pressure (BP) management during transfer of patients with ruptured abdominal aortic aneurysm (rAAA). This study evaluates the effects of hypertension and severe hypotension during inter-hospital transfers in a cohort of rAAA in hemorrhagic shock. METHODS: We performed a retrospective, single institution review of rAAA patients transferred via air ambulance to a quaternary referral center for repair (2003-2019). Vitals were recorded every five minutes in transit...

The demand for thorough disinfection within ambulances is essential, given the in-vehicle medical procedures and the potential high risk of infections due to patients' open wounds. One solution that can address this hygiene challenge involves the application of reactive products generated from atmospheric (air) oxygen and water vapor, activated through the use of cold plasma. Cold plasma's charged particles perforate the cell membranes of microorganisms. This process does not work in human cells, as proteins in the form of enzymes within the body break down the cold plasma and protect the cells...

Binge drinking is one of the most common patterns (more than 90%) of alcohol consumption by young people. During adolescence, the brain undergoes maturational changes that influence behavioral control and affective behaviors, such as cerebellar brain volume and function in adulthood. We investigated long-term impacts of adolescent binge ethanol exposure on affective and exploratory behaviors and cerebellar gene expression in adult male and female mice. Further, the cerebellum is increasingly recognized as a brain region integrating a multitude of behaviors that span from the traditional primary sensory-motor to affective functions, such as anxiety and stress reactivity...
