CONTEXT While the adoption of practice guidelines is standardizing many aspects of patient care, ethical dilemmas are occurring because of forgoing life-sustaining therapies in intensive care and are dealt with in diverse ways between different countries and cultures. OBJECTIVES To determine the frequency and types of actual end-of-life practices in(More)
Objective: Incidence, types, and factors associated with new onset tachyarrhythmias (TA) in surgical intensive care patients.¶Design: Pairwise-matched case-controlled study. Setting: Surgical intensive care unit (ICU) with nine intensive care beds. Patients: During a 1-year period, all TA patients (n = 89) were included in the study. Control patients (n =(More)
Snow avalanche case reports have documented the survival of skiers apparently without permanent hypoxic sequelae, after prolonged complete burial despite there being only a small air pocket on extrication. We investigated the underlying pathophysiological changes in a prospective, randomised 2 x 2 crossover study in 12 volunteers (28 tests) breathing into(More)
BACKGROUND Low-molecular-weight heparins (LMWHs) have become increasingly used to prevent thromboembolic complications in intensive care patients. Unlike in medical and surgical patients, no data on the anticoagulant effectiveness of standard LMWH dosages exist in intensive care patients. Therefore, we prospectively investigated antifactor Xa (aFXa) levels(More)
Colloids and crystalloids are usually administered as treatment for hypovolemia in severely injured patients. However, dilution of clotting factors and platelets together with impaired fibrinogen polymerization are associated with fluid therapy and may aggravate hemorrhage, thus worsening final outcome of these patients. We investigated, in an in vitro(More)
To evaluate physicians' reasoning, considerations and possible difficulties in end-of-life decision-making for patients in European intensive care units (ICUs). A prospective observational study. Thirty-seven ICUs in 17 European countries. A total of 3,086 patients for whom an end-of-life decision was taken between January 1999 and June 2000. The dataset(More)
OBJECTIVE Circulating serum levels of procalcitonin rise significantly during bacterial infection. Because calcitonin is known to be a monocyte chemoattractant, we investigated whether procalcitonin, a prohormone of calcitonin, also affects leukocyte migration. DESIGN Prospective, controlled in vitro study. SETTING University research laboratories. (More)
A possible contribution of exercise to the fluid retention associated with acute mountain sickness (AMS) was investigated in 17 mountaineers who underwent an exercise test for 30 min on a bicycle ergometer with a constant work load of 148 +/- 9 (SE) W at low altitude (LA) and with 103 +/- 6 W 4-7 h after arrival at 4,559 m or high altitude (HA). Mean heart(More)
The present study was performed to investigate the effects of exhaustive long lasting exercise at moderate altitude on the time course of serum immunomodulatory peptides, vascular endothelial growth factor (VEGF) and serum erythropoietin (EPO). Thirteen well trained runners participated at the Swiss Alpine Marathon of Davos (distance 67 km, altitude(More)
UNLABELLED To explore whether routinely administered colloids and crystalloids influence the hemostatic system, we studied 60 patients undergoing knee replacement surgery during randomized intravascular fluid administration using 6% hydroxyethyl starch 200/0.5 (HES) or 4% modified gelatin (GEL) in addition to a basal infusion of lactated Ringer's solution(More)
