Review Meta Analysis[Supplemental oxygen for the prevention of postoperative nausea and vomiting: a meta-analysis of randomized clinical trials].
Despite the development of antiemetic drugs, the incidence of postoperative nausea and vomiting remains between 20% and 30%. This meta-analysis examines the hypothesis that perioperative administration of supplemental oxygen reduces the incidence of these complications. ⋯ Supplemental oxygen reduces the incidence of postoperative vomiting. Administration of supplemental oxygen could be an effective method of reducing postoperative vomiting but does not replace current indications for pharmacologic prophylaxis.

Review[Minimally invasive cardiopulmonary monitoring with the PiCCO Plus system].
Insertion of a central venous catheter and an arterial catheter would be indicated in hemodynamically unstable or severely hypoxic patients in critical care units. In this setting, cardiorespiratory monitoring by transpulmonary thermodilution (TPTD) can be considered minimally invasive given that only a single arterial thermodilution catheter and a single central venous catheter are required to be connected to a specific monitor (the PiCCO Plus, Pulsion Medical Systems, Munich, Germany). ⋯ The technique can be managed by any health care professional. In hypoxic patients, TDTP identifies cases of pulmonary edema that might benefit from a negative fluid balance, evaluates pulmonary vascular permeability, facilitates our understanding of pathophysiologic mechanisms of hypoxemia, and predicts the likelihood of deleterious hemodynamic effects of positive end-expiratory pressures.

Review[Monitoring of oxygen pressure in brain tissue in severely injured patients under neurocritical care].
Head injury continues to be the main cause of mortality and morbidity among young people in Europe. The use of technology in managing severe head injury has increased considerably and certain applications may be confusing to physicians who have little experience in neurology but who are charged with providing neurocritical care. ⋯ Continuous monitoring of the partial oxygen pressure of brain tissue (PtO2) has become more common in neurocritical care units, making bedside evaluation of the effects of injuries and therapeutic measures possible. This review discusses technical, safety, and reliability aspects of PtO2 monitoring and its potential advantages in comparison with other techniques for evaluating brain tissue oxygenation.

Review[Applications for bronchial blockers in thoracic surgery].
One-lung ventilation is commonly used to facilitate visualization of the field during thoracic surgery. New devices for performing this technique that have become available over the past 2 decades include the Univent bronchial blocker incorporated in a single-lumen tube, the Arndt endobronchial blocker, and the Cohen endobronchial blocker. ⋯ The literature search was performed on MEDLINE through PubMed using the keywords bronchial blockers and thoracic surgery. The search span started with 1982-the year the first modern bronchial blocker was described - and ended with February 2006.

Sepsis and consequent multiorgan dysfunction syndrome are responsible for over 60% of deaths in patients receiving critical care in spite of improvements in patient management. We describe the pathophysiology, epidemiology, clinical picture, and biochemical markers that contribute to the diagnosis and assessment of infection severity and progression of infection to sepsis and from severe sepsis to septic shock. Our focus is on the guidelines of the Surviving Sepsis Campaign, complemented with additional information published since those guidelines appeared. The Ovid MEDLINE database was used for a search from 1997 through 2006.
