Intra-operative gut mucosal hypoperfusion is associated with increased post-operative complications and cost.
To determine CO and gastric mucosal perfusion in patients during elective major surgery; to seek a relationship with subsequent outcome. ⋯ A low gastric pHi measured during the intraoperative period in a group of patients undergoing major (mainly cardiovascular) surgery is associated with increased post-operative complications and cost.

Comparative StudySignificance of pathologic oxygen supply dependency in critically ill patients: comparison between measured and calculated methods.
oxygen supply dependency at normal or high oxygen delivery rate has been increasingly proposed as a hallmark and a risk factor in critical illnesses. We hypothesized that as far as an adequate oxygen delivery is provided, oxygen consumption, when determined by indirect calorimetry, is not dependent on oxygen delivery in critically ill patients whereas calculated oxygen consumption is associated with artefactual correlation of oxygen consumption and delivery. ⋯ analysis of oxygen uptake, when measured by indirect calorimetry, failed to substantiate oxygen supply dependency in the vast majority of the critically ill patients irrespective of diagnosis and outcome. Mathematical coupling of shared variables accounted for the correlation between oxygen delivery and calculated oxygen consumption.

Case ReportsContinuous monitoring of blood gases during hypercapnia in a patient with severe acute lung failure.
We report about our first experiences with a new device for continuous intra-arterial monitoring of blood gases in a patient with severe acute respiratory failure. This device facilitated continuous monitoring of PaO2, PaCO2 and pH while weaning the patient from extracorporeal membrane oxygenation (ECMO). ⋯ Within six hours, PaCO2 increased to 95 mmHg. Continuous monitoring of pH and PaCO2 helped to monitor CO2 retention and assisted the decision making process for reinstitution of ECMO.

Risk factors for infection by Pseudomonas aeruginosa in patients with ventilator-associated pneumonia.
to investigate the epidemiology of infection by Pseudomonas aeruginosa in patients with ventilator-associated pneumonia (VAP). ⋯ patients with VAP and these factors have a greater risk of infection by Ps. aeruginosa and empirical therapy for these episodes should include anti-pseudomonal activity until etiologic diagnosis is established.

Case ReportsPropofol in the management of refractory status epilepticus: a case report.
Status epilepticus is one of the most frequent neurological emergencies in the intensive care unit. Standard treatment includes intravenous barbiturates, benzodiazepines and phenytoin. However, drug coma is sometimes necessary to control refractory status epilepticus. We report such a case, successfully treated by intravenous propofol coma to EEG burst suppression.
