BACKGROUND For patients with ST-elevation myocardial infarction (STEMI), guidelines recommend prehospital triage and direct referral to a percutaneous coronary intervention (PCI)-capable centre in order to minimize ischemic time. However, few have studied failed prehospital diagnosis. We assessed the incidence, predictors, and clinical impact of(More)
INTRODUCTION Inter-hospital transport of critically ill patients is increasing. When performed by specialized retrieval teams there are less adverse events compared to transport by ambulance. These transports are performed with technical equipment also used in an Intensive Care Unit (ICU). As a consequence technical problems may arise and have to be dealt(More)
BACKGROUND & AIMS Both undernutrition - low fat free mass (FFM) - and obesity - high fat mass (FM) - have been associated with adverse outcome in cardiac surgical patients. However, whether there is an additional effect on outcome of these risk factors present at the same time, that is sarcopenic obesity (SO), is unknown. Furthermore, the association(More)
OBJECTIVE To describe the triage of patients operated for non-ruptured and ruptured abdominal aortic aneurysms (AAAs) before the endovascular era. DESIGN Retrospective single-centre cohort study. METHODS All patients treated for an acute AAA between 1998 and 2001 and admitted to our hospital were evaluated in the emergency department for urgent AAA(More)
BACKGROUND There is controversy about performing either a planned relaparotomy (PR) or relaparotomy on demand (ROD) in patients with secondary peritonitis. Subjective factors influencing surgeons in decision making for either surgical treatment strategy have never been studied. METHODS All 858 surgeons of the Association of Surgeons of The Netherlands(More)
AIMS Inherited cardiac diseases play an important role in sudden death (SD) in the young. Autopsy and cardiogenetic evaluation of relatives of young SD victims identifies relatives at risk. We studied the usual care after SD in the young aimed at identifying inherited cardiac disease, and assessed the efficacy of two interventions to improve this usual(More)
BACKGROUND/AIMS To provide a qualitative ranking of clinical variables by surgeons that influence their decision for reoperation and to evaluate whether these variables are related to positive findings at relaparotomy. METHODS Importance in decision making for relaparotomy was evaluated for 21 factors using a 10-point visual analogue scale (VAS).(More)
BACKGROUND Early initiation of continuous positive airway pressure (CPAP) applied by face mask benefits patients with acute cardiogenic pulmonary oedema (ACPE). The simple disposable Boussignac CPAP (BCPAP) has been used in ambulances by physicians. In the Netherlands, ambulances are manned by nurses and not physicians. It was hypothesised that ambulance(More)
BACKGROUND Treatment rates with intravenous tissue plasminogen activator vary by region, which can be partially explained by organizational models of stroke care. A recent study demonstrated that prehospital factors determine a higher thrombolysis rate in a centralized vs. decentralized model in the north of the Netherlands. AIM To investigate prehospital(More)
AIM Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. METHODS The frequency and outcome of a large cohort of hydrogen sulphide(More)
