We report a forty-six-year-old man with a past history of brain abscess managed by surgical drainage and recurrent ischemic strokes. After treatment of brain abscess, he had been on medication for symptomatic epilepsy, but had ceased medication by his judgment. He was taken to a hospital in an ambulance for an epileptic seizure. In the hospital he suffered from drug-induced renal dysfunction caused by the intravenous anti-epileptic drug, and right hemiparesis due to ischemic stroke occurred on the third hospitalization day...

INTRODUCTION: Despite the prevalence of fixed wing medical flights for specialized care and repatriation, few acuity rating scales exist aimed at the prediction of adverse in-flight medical events. An acuity scoring system can provide information to flight crews, allowing for staffing enhancements, protocol modifications, and flight planning, with the aim of improving patient care, outcomes, and preventing losses to providers because of costly diversions. METHODS: Our medical crew developed an acuity scale, which was applied retrospectively to 296 patients transported between January 2016 and March 2017...

OBJECTIVES: We investigated how often intravenous fluids have been delivered during physician-led prehospital treatment of patients with hypotensive trauma in the UK and which fluids were given. These data were used to estimate the potential national requirement for prehospital blood products (PHBP) if evidence from ongoing trials were to report clinical superiority. SETTING: The Regional Exploration of Standard Care during Evacuation Resuscitation (RESCUER) retrospective observational study was a collaboration between 11 UK air ambulance services...

An 80-year-old woman was brought to our hospital in an ambulance because of signs of peritoneal irritation. Computed tomography revealed volvulus, sigmoid colon dilation, and free air and pneumatosis within the colonic and bowel wall. An emergency laparotomy was performed after the diagnosis of colonic perforation associated with volvulus or pneumatosis. Numerous gas-filled cysts, up to 10mm in diameter, were located in the resected bowel wall. The cells at the inner lining of the cysts tested positive for D2-40 immunoreactivity, seemingly originating from the lymphatic vessels...

The aim of the present study was to evaluate the performance of regional oxygen saturation (rSO2) monitoring with near infrared spectroscopy (NIRS) during pediatric inter-hospital transports and to optimize processing of the electronically stored data. Cerebral (rSO2-C) and abdominal (rSO2-A) NIRS sensors were used during transport in air ambulance and connecting ground ambulance. Data were electronically stored by the monitor during transport, extracted and analyzed off-line after the transport. After removal of all zero and floor effect values, the Savitzky-Golay algorithm of data smoothing was applied on the NIRS-signal...

BACKGROUND: In developed countries, ambulances normally carry oxygen cylinders but not compressed air. Treatment of acute exacerbations of COPD (AECOPD) with oxygen-driven nebulisers can result in hypercapnia and acidosis. Attempts to avoid this have involved interrupted administration of oxygen.1 However, small battery-powered air nebulisers are now available. AIMS: This study aims to compare the prehospital oxygen saturations and treatment of patients suffering from AECOPD before and after the introduction of air nebulisers...

We investigated the association between daily emergency ambulance calls (EAC) for elevated blood pressure that occurred during the time intervals of 8:00-13:59, 14:00-21:59, and 22:00-7:59, and exposure to CO, PM10 , and ozone. We used Poisson regression to explore the association between the risk of EAC and short-term variation of pollutants, adjusting for seasonality and weather variables. Before noon, the risk was associated with an interquartile range (IQR) (7.9 μg/m3 ) increase in PM10 at lag 2-4 days below the median (RR = 1...

AIM: Guidelines recommend detecting return of spontaneous circulation (ROSC) by a rising concentration of carbon dioxide in the exhalation air. As CO2 is influenced by numerous factors, no absolute cut-off values of CO2 to detect ROSC are agreed on so far. As trends in CO2 might be less affected by influencing factors, we investigated an approach which is based on detecting CO2 -trends in real-time. METHODS: We conducted a retrospective case-control study on 169 CO2 time series from out of hospital cardiac arrests resuscitated by Muenster City Ambulance-Service, Germany...

OBJECTIVE: The potential increased risk of an emergency response using a rapid response vehicle (RRV) should only be accepted when it allows a clinically significant time saving for management of patients who are critically injured or sick. Air ambulance services often use an RRV to maintain operational resilience. We compared the RRV response time on emergency versus standard driving to inform emergency services of time efficacy of emergency response in an urban environment. METHODS: Prospective observational controlled study of response data of emergency and standard driving...

INTRODUCTION: The current management of severely injured patients includes damage control resuscitation strategies that minimise the use of crystalloids and emphasise earlier transfusion of red blood cells (RBC) to prevent coagulopathy. In 2012, London's air ambulance (LAA) became the first UK civilian pre-hospital service to routinely carry RBC to the trauma scene. OBJECTIVE: To investigate the effect of pre-hospital RBC transfusion (phRTx) on overall blood product consumption...

BACKGROUND: Even in a landlocked country like Switzerland recreational diving is becoming more and more popular. Smaller lakes in the Alps are located at an altitude of 2500 m above sea level. The incidence of diving accidents among all helicopter emergency service missions and the consecutive medical knowledge about decompression injuries is low. Thus, a collaboration between the Swiss Air-Ambulance (Rega) and the divers alert network (DAN) was initiated to improve patient treatment and identification of decompression injury and necessity of hyperbaric oxygen therapy (HBO)...

Sternal and rib fractures are well-known complications of cardiopulmonary resuscitation (CPR). We experienced a rare case of traumatic gastric perforation associated with CPR that required emergency laparotomy. In this case, we examined whether surgery is essential for gastric perforation associated with CPR. A 67-year-old man experienced cardiopulmonary arrest in the workplace, and bystander CPR was performed by his colleagues. He was then transported by ambulance to our hospital. A large amount of free air was found in the peritoneal cavity on computed tomography at presentation, and perforation of the gastrointestinal tract was suspected...
