Accuracy of a novel approach to measuring arterial thermodilution cardiac output during intra-aortic counterpulsation.
To assess the agreement between a novel approach of arterial and the pulmonary artery bolus thermodilution for measuring cardiac output in critically ill patients during aortic counterpulsation. ⋯ Agreement between BCO(iabp) and BCO(pulm) was satisfactory for CO values between 2.0 and 10 l/min only without aortic counterpulsation. BCO(iabp) CO measurements during aortic counterpulsation after coronary artery bypass grafting cannot be recommended at the present time.

Use of radio frequency identification (RFID) tags in bedside monitoring of endotracheal tube position.
Improper positioning of the endotracheal tube during intubation poses a serious health risk to patients. In one prospective study of 219 critically ill patients, 14% required endotracheal tube repositioning after intubation [Brunel et al. ⋯ RFID technology has already been approved for use in humans as a safe and effective tool in a variety of applications. The use of handheld RFID detectors and RFID tag-labeled endotracheal tubes could allow for easy and accurate bedside monitoring of endotracheal tube position, once initial proper placement is confirmed.

Direct measurement of intra-abdominal pressure with a solid microtranducer.
To describe a direct intra-abdominal pressure (IAP) measurement technique using a solid microsensor comparing its values with the ones simultaneously obtained by means of Kron's technique. Comparative study between two different methods to measure intra-abdominal pressure in a multidisciplinary intensive care unit of a university hospital. ⋯ Direct IAP measurement with a Codman microsensor allows continuous monitoring without urinary tract manipulation, is simple to use and to calibrate, minimally invasive and appropriate for patients at risk to develop abdominal compartmental syndrome. Due to its cost it should be reserved for selected critical patients where standard techniques are contraindicated or can be inaccurate.

Corrected incidences of co-morbidities - a statistical approach for risk-assessment in anesthesia using an AIMS.
In anesthesia and intensive care logistic regression analysis are often used to generate predictive models for risk assessment. Strictly seen only independent variables should be represented in such prognostic models. Using anesthesia-information-management-systems a lot of (depending) information is stored in a database during the preoperative ward round. The objective of this study was to evaluate a statistical algorithm to process the different dependent variables without losing the information of each variable on patient's conditions. ⋯ Due to reduced calibration, the clinical use of the prediction model is limited.

Controlled Clinical TrialHypotension induced by lateral decubitus or supine spinal anaesthesia in elderly with low ejection fraction undergone hip surgery.
The aim of the study was to assess the effect of low ejection fraction (EF) on hypotension during lateral or supine position of spinal anaesthesia in patients older than 75 years old. ⋯ Elderly patients with low EF were more likely to predispose to higher sensorial block level and hypotension was more common during spinal anaesthesia with supine position compared to lateral decubitus position.
