Postoperative cognitive function (POCD) has been subject to extensive research. In the literature, large differences are apparent in methodology such as the test batteries, the interval between sessions, the endpoints to be analysed, statistical methods, and how neuropsychological deficits are defined. Traditionally, intelligence tests or tests developed(More)
CONTEXT Use of 80% oxygen during surgery has been suggested to reduce the risk of surgical wound infections, but this effect has not been consistently identified. The effect of 80% oxygen on pulmonary complications has not been well defined. OBJECTIVE To assess whether use of 80% oxygen reduces the frequency of surgical site infection without increasing(More)
BACKGROUND Protein S100B has proven to be a useful biomarker for cerebral damage. The predictive ability of S100B may, however, be affected by extracerebral injuries. The aim of this study was to investigate serum levels of S100B in patients with either isolated head injury (IHI), multi trauma with head injury (MTHI), or no head injury (NHI). The primary(More)
OBJECTIVE Age is considered to be the strongest predictive factor of postoperative cognitive dysfunction (POCD) after cardiac surgery. Coronary artery bypass grafting (CABG) without the use of cardiopulmonary bypass is considered to be less harmful to the patient, especially in terms of neurological complications. METHODS The study was a sub-study of the(More)
Postoperative cognitive dysfunction (POCD) is a subtle impairment of memory, concentration, and speed of information processing. It is a frequent complication following surgery and can have a debilitating effect on patients' recovery and future prognosis. Neuropsychological testing is needed to reveal postoperative cognitive decline, and questionnaires are(More)
INTRODUCTION Rapid recognition of stroke is important because it allows early brain imaging and management such as thrombolytic therapy. We evaluated the identification of the diagnosis acute cerebrovascular incident in a physician-based prehospital emergency medical system. METHODS From the Copenhagen Mobile Emergency Care Unit (MECU) register we(More)
BACKGROUND Tissue injury increases blood levels of extracellular histones and nucleic acids, and these may influence hemostasis, promote inflammation and damage the endothelium. Trauma-induced coagulopathy (TIC) may result from an endogenous response to the injury that involves the neurohumoral, inflammatory and hemostatic systems. AIMS To study the(More)
BACKGROUND Because most cardiac arrests occur at home, widespread training is needed to increase the incidence of cardiopulmonary resuscitation (CPR) by lay persons. The aim of this study was to evaluate the effect of mass distribution of CPR instructional materials among schoolchildren. METHODS AND RESULTS We distributed 35,002 resuscitation manikins to(More)
BACKGROUND A high perioperative inspiratory oxygen fraction may reduce the risk of surgical site infections, as bacterial eradication by neutrophils depends on wound oxygen tension. Two trials have shown that a high perioperative inspiratory oxygen fraction (FiO(2) = 0.80) significantly reduced risk of surgical site infections after elective colorectal(More)
OBJECTIVE Previous trials comparing coronary artery bypass grafting (CABG) with or without extracorporeal circulation have mainly enrolled selected patients at younger age and low risk. Patient-reported health-related quality of life has not been significantly different. We compared health-related quality of life in elderly moderate to high-risk patients(More)
