The patient state index (PSI) is a clinically validated measure of the effect of anaesthesia and sedation. The PSI is calculated via a proprietary algorithm by a high-resolution 4-channel electroencephalograph (EEG) monitor after advanced artifact rejection. ⋯ The EEG monitor, initially called the PSA4000, is also the SEDLine monitor, the newest generation of the device. The SEDLine system provides the clinician the option of storing and downloading patient data for future use as well as monitoring bilateral brain function and symmetry with a density spectral array (DSA) display.

To summarize the evidence comparing noninvasive positive pressure ventilation (NPPV) and invasive positive pressure ventilation (IPPV) weaning on mortality, ventilator associated pneumonia and the total duration of mechanical ventilation among invasively ventilated adults with respiratory failure. ⋯ In the absence of a large randomized controlled trial, this meta-analysis demonstrated a consistent positive effect of noninvasive weaning on mortality. Notwithstanding, the use of NPPV to facilitate weaning, in mechanically ventilated patients, with predominantly chronic obstructive pulmonary disease, is associated with promising, but insufficient, evidence of net clinical benefit at present.

This review focuses on recent advances in the treatment of traumatic brain injury (TBI) during 2004 and 2005. Injured brain is a very heterogeneous structure, significantly evolving over time. Implementation of multimodal neuromonitoring will certainly provide more insights into pathophysiology of TBI. ⋯ Hypertonic saline may become a preferred osmotherapeutic agent in severely head-injured patients, especially those with refractory intracranial hypertension. Benefit and indications for performing a decompressive craniectomy remain to be determined. Overall, individualized treatment respecting actual status of a patient's intra- and extracranial homeostasis should be the key principle of our current therapeutic approach toward severely head-injured patients.

Intensive care unit physician staffing: financial modeling of the Leapfrog standard.
To evaluate from a hospital's perspective the costs and savings, over a 1-yr period, of implementing The Leapfrog Group's Intensive Care Unit Physician Staffing (IPS) standard compared with the existing standard of nonintensivist staffing in adult intensive care units. ⋯ Financial modeling of implementation of the IPS standard using conservative assumptions demonstrated cost savings to hospitals. Only under worst-case scenario assumptions did intensivist staffing result in additional cost to hospitals. These economic findings must be interpreted in the context of significant reductions in patient morbidity and mortality rates also associated with intensivist staffing. Given the magnitude of its clinical and financial impact, hospital leaders should be asking "how to" rather than "whether to" implement The Leapfrog Group's ICU Physician Staffing standard.
