Comparative StudyValidation of severity scoring systems SAPS II and APACHE II in a single-center population.
To validate two severity scoring systems, the Simplified Acute Physiology Score (SAPS II) and Acute Physiology and Chronic Health Evaluation (APACHE II), in a single-center ICU population. ⋯ This study validates both SAPS II and APACHE II scores in an ICU population comprised mainly of surgical patients. The type of ICU admission and the location in the hospital before ICU admission influence the predictive ability of the models.

Comparative StudyAccuracy of totally implanted ports, tunnelled, single- and multiple-lumen central venous catheters for measurement of central venous pressure.
To verify the accuracy of totally implanted ports, tunnelled central venous catheters (CVC), widely used in cancer patients, and multi-lumen catheters, used in intensive care units (ICUs), in measuring central venous pressure (CVP), using right atrial pressure (RAP) measured in a Swan-Ganz catheter as the reference standard. ⋯ CVP can be accurately measured in totally implanted ports, tunnelled or non-tunnelled single-lumen and multiple-lumen catheters. When the difference exceeds the limit of agreement, the discrepancy between the two measurements has limited significance in most cases.

Clinical Trial Controlled Clinical TrialDifferent dosages of dobutamine in septic shock patients: determining oxygen consumption with a metabolic monitor integrated in a ventilator.
Oxygen consumption (VO2) obtained from respiratory gases by indirect calorimetry (VO2,IC) with a metabolic monitor integrated in a ventilator were to be compared to VO2 obtained by the Fick principle (VO2,Fick) in septic patients following an increase in oxygen delivery (DO2) induced by positive inotropic support. ⋯ With a metabolic monitor integrated in a ventilator it was possible to carry out continuous monitoring of calorimetric data under clinical conditions. In contrast to previous studies using indirect calorimetry, this study showed a moderate correlation between VO2 and DO2 in septic patients using either method. The clinical relevance of this finding requires further investigation. Different factors (e. g. injectant temperature, pulmonary VO2) produced substantial differences between VO2,IC and VO2,Fick as previously shown.

ICU nurse-to-patient ratio is associated with complications and resource use after esophagectomy.
To determine if having a night-time nurse-to-patient ratio (NNPR) of one nurse caring for one or two patients (> 1:2) versus one nurse caring for three or more patients (< 1:2) in the intensive care unit (ICU) is associated with clinical and economic outcomes following esophageal resection. ⋯ A nurse caring for more than two ICU patients at night increases the risk of several postoperative pulmonary and infectious complications and was associated with increased resource use in patients undergoing esophageal resection.

Predictive factors of death in primary lung cancer patients on admission to the intensive care unit.
To assess the lung cancer patient's prognosis in the intensive care unit with early predictive factors of death. ⋯ We confirmed the high mortality rate of lung cancer patients admitted to the MICU. Two predictive factors of death in MICU were identified: performance status < 70 and acute pulmonary disease.
