INTRODUCTION The prognostic value of emergency echocardiography (EE) in the management of cardiac arrest patients has previously been studied in an in-hospital setting. These studies mainly included patients who underwent cardiopulmonary resuscitation (CPR) by emergency medicine technicians at the scene and who arrived at the emergency department (ED) still(More)
This trial was designed to study the correlation between peri-operative mortality in patients undergoing elective surgery and the physical status classification of the American Society of Anesthesiologists, the Goldman multifactorial cardiac risk index or the two indices combined. All patients scheduled for elective surgery over a 5-year period were(More)
OBJECTIVE The preoperative classifications: physical status of the American Society of Anesthesiologists (ASA-PS) and/or cardiac risk index (CRI) of Goldman are widely used to estimate the perioperative risk in patients undergoing noncardiac throacic surgery. We tried to determine the validity of both methods in predicting the perioperative mortality in 845(More)
The continuity of chest compression is the main challenge in prehospital cardiopulmonary resuscitation in the field as well as during transport. Invasive blood pressure monitoring with visible pulse waves by means of an arterial line set prehospitally allows for tight control of the effectiveness of chest compressions as well as of the impact of the(More)
BACKGROUND The decision "patient unfit for anaesthesia and operation" is likely to cause a delay of the scheduled operation. This retrospective evaluation was done: 1) to determine the correctness of preoperative tentative diagnoses of coexisting diseases making anaesthesia and operation excessively risky in relation to the physician's training status; 2)(More)
AIM As recent clinical data suggest a harmful effect of arterial hyperoxia on patients after resuscitation from cardiac arrest (CA), we aimed to investigate this association during cardiopulmonary resuscitation (CPR), the earliest and one of the most crucial phases of recirculation. METHODS We analysed 1015 patients who from 2003 to 2010 underwent(More)
OBJECTIVE To use scientific methods to evaluate 2 claims made by practitioners of alternative medicine. DESIGN A placebo-controlled, double-blind study of homeopathy in children with warts, and a cohort study of the influence of lunar phases on postoperative outcome in surgical patients. SETTING Outpatients of a dermatology department (homeopathy study)(More)
During cardiopulmonary resuscitation, pH and base excess (BE) decrease to a variable degree due to metabolic acidosis. The main cause has been shown to be lactate, which cannot be eliminated sufficiently because of low perfusion during cardiac massage. Both BE and lactate can be measured in the prehospital phase. The aim of the study was to determine if BE(More)
