OBJECTIVE Most patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) initially present to a hospital that lacks a neurosurgical unit. These patients require interhospital transfer (IHT) to tertiary facilities capable of multidisciplinary neurosurgical intervention. Yet, little is known about the effects of IHT on the outcomes of patients suffering from aSAH. In this study, the authors examined the effects of IHT and transport method on the timing of treatment, rebleed rates, and overall outcomes of patients who have experienced aSAH...

INTRODUCTION: Injured children may be transported to trauma centers by helicopter air ambulance (HAA); however, a benefit in outcomes to this expensive resource has not been consistently shown in the literature and there is concern that HAA is over-utilized. A study that adequately controls for selection biases in transport mode is needed to determine which injured children benefit from HAA. The purpose of this study was to determine if HAA impacts mortality differently in minimally and severely injured children and if there are predictors of over-triage of HAA in children that can be identified...

BACKGROUND: The response speed of ambulance calls is very crucial to rescue patients suffering immediately life threatening conditions. The serious health outcomes might be caused by exposing to extreme heat only several hours before. However, limited evidence is available on this topic. This study aims to examine the hourly association between heat and ambulance calls, to improve the ambulance services and to better protect health. METHODS: Hourly data on ambulance calls for non-accidental causes, temperature and air pollutants (PM10, NO2, and O3) were collected from Brisbane, Australia, during 2001 and 2007...

BACKGROUND: Although the effects of noise on population morbidity and mortality have been observed both in the short and long term, the morbidity and mortality indicators used to date have not enabled information on such health effects to be accessed in real time. At an international level, there are relatively few studies, mostly recent, which have considered an alternative indicator, such as the demand for medical attention provided by emergency services, taking into account environmental factors other than noise...

BACKGROUND: Out-of-hospital cardiac arrest is a life threatening situation where the first person performing cardiopulmonary resuscitation (CPR) most often is a bystander without medical training. Some existing smartphone apps can call the emergency number and provide for example global positioning system (GPS) location like Hjelp 113-GPS App by the Norwegian air ambulance. We propose to extend functionality of such apps by using the built in camera in a smartphone to capture video of the CPR performed, primarily to estimate the duration and rate of the chest compression executed, if any...

Out-of-hospital cardiac arrest (OHCA) is becoming a considerable public health burden worldwide. The seasonal variation of OHCA has been observed, but the potential effects of ambient temperature on OHCA were rarely investigated. We, therefore, aimed to evaluate the association between ambient temperature and OHCA in Guangzhou, China. We collected daily emergency ambulance dispatches for OHCA from the Guangzhou Emergency Center from January 1, 2008 to December 31, 2012. We analyzed the associations using the time-series method...

We present a rare case of a 74 year old man admitted by ambulance to our department following a blunt minor abdominal trauma (veal attack). He complained of pain in the left abdominal flank and in the lower abdomen. The lower abdomen was tender, moderate distended but not rigid. He also had a left inguinal uncomplicated hernia. Because he was hemodynamic stable we performed a CT - scan who revealed several pockets of free air anteriorly in the midline. One hour and a half after admission the pacient underwent exploratory laparotomy, revealing a antimesostenic perforation of the ileum about 120 cm from the ileo-cecal valve...

This report describes the first use of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in the pre-hospital setting to control catastrophic haemorrhage. The patient, who had fallen 15 meters, suffered catastrophic internal haemorrhage associated with a pelvic fracture. He was treated by London's Air Ambulance's Physician-Paramedic team. This included insertion of a REBOA balloon catheter at the scene to control likely fatal exsanguination. The patient survived transfer to hospital, emergency angio-embolization and subsequent surgery...

The study examined the effects of hypoxia and horizontal bed rest, separately and in combination, on peak oxygen uptake (V̇o2 peak) during upright cycle ergometry. Ten male lowlanders underwent three 21-day confinement periods in a counterbalanced order: 1) normoxic bed rest [NBR; partial pressure of inspired O2 (PiO2 ) = 133.1 ± 0.3 mmHg]; 2) hypoxic bed rest (HBR; PiO2 = 90.0 ± 0.4 mmHg), and 3) hypoxic ambulation (HAMB; PiO2 = 90.0 ± 0.4 mmHg). Before and after each confinement, subjects performed two incremental-load trials to exhaustion, while inspiring either room air (AIR), or a hypoxic gas (HYPO; PiO2 = 90...
