Randomized Controlled Trial Multicenter Study Comparative StudyCisatracurium versus vecuronium: a comparative, double blind, randomized, multicenter study in adult patients under propofol/fentanyl/N2O anesthesia.
The aim of this study was to compare the time course characteristics of cisatracurium (C) and vecuronium (V) induced neuromuscular block (NMB) following multiple doses, allowing spontaneous complete recovery (SCRT) and evaluating the influence of age. ⋯ C and V allow predictable NMB duration and spontaneous recovery even if administered in multiple repeated doses; but in elderly patients duration of block and recovery time is longer following V.

ReviewMolecular biology on the ICU. From understanding to treating sepsis.
Mounting evidence suggests that beside well established factors, such as virulence of pathogens or site of infection, individual differences in disease manifestation are a result of the genetic predisposition of the patient on an Intensive Care Unit (ICU). Specific genetic factors might not only predict the risk to acquire severe infections but also to develop organ dysfunction or ultimately to die. ⋯ Similarly, knowledge of genetic factors might in the near future help to identify ''patients at risk'', i.e. those with a high likelihood to develop organ dysfunction or to guide therapeutic interventions in particular regarding resource-consuming and/or expensive therapies (''theragnostics''). While therapeutic options in molecular intensive care medicine, such as stem cells in the treatment of organ failure or therapeutic gene transfer are possible along the road and might become an option in the future, recombinant DNA technology has already a well defined role in the production of recombinant human proteins from insulin to activated protein C.

Complications of liver disease are commonly seen in the intensive care unit (ICU). When evaluating patients with liver disease in the ICU, it is important to determine whether it is acute or chronic liver disease. ⋯ Chronic liver disease is best discussed in terms of the various complications that may ensue such as ascites, hepatorenal syndrome, spontaneous bacterial peritonitis, variceal hemorrhage and hepatic encephalopathy. Each of these conditions will be discussed with specific attention to critical care management.

Comparative StudyBispectral Index compared to Ramsay score for sedation monitoring in intensive care units.
Continuous monitoring is of paramount importance in order to obtain a correct level of sedation in ICU patients. Clinical scoring systems, although simple and inexpensive, are often inadequate in evaluating the patient level of consciousness. Among instrumental tools for sedation monitoring, Bispectral Index (BIS) is now widely used due to its reliability and applicability. Nevertheless some doubts still exist regarding its usefulness in ICU. ⋯ BIS monitoring is useful in ICU patients and allows a finest differentiation of sedation level in deeply sedated ICU patients.

ReviewRisks, benefits, alternatives and indications of allogenic blood transfusions.
Allogeneic red blood cell (RBC) transfusions are associated with multiple disadvantages, such as limited availability, high costs, multiple risks and side effects. In addition, large outcome studies comparing liberal (hemoglobin transfusion trigger range 9-10 g/dL) and restrictive (hemoglobin transfusion trigger range 7-9 g/dL) transfusion regimens still need to be performed for surgical patients. Different transfusion alternatives are known for the pre-, intra- and postoperative period. ⋯ RBC transfusions are recommended under the following circumstances: for hemoglobin levels <6 g/dL and for physiologic signs of inadequate oxygenation such as hemodynamic instability, oxygen extraction rate >50% and myocardial ischemia, detectable by new ST-segment depressions >0.1 mV, new ST-segment elevations >0.2 mV or new wall motion abnormalities by transesophageal echocardiography. The aim of this article is to review the efficacy, risk and side effects of RBC transfusions, to discuss transfusion alternatives and to summarize current indications for RBC transfusions. This information will help the physician to judiciously use RBC transfusions when they are indeed indicated.
