Multicenter Study Comparative Study
Comparison of two methods for cardiac output measurement in critically ill patients.
The aim of recent haemodynamic monitoring has been to obtain continuous and reliable measures of cardiac output (CO) and indices of preload responsiveness. Many of these methods are based on the arterial pressure waveform analysis. The aim of our study was to assess the accuracy of CO measurements obtained by FloTrac/Vigileo, software version 1.07 and the new version 1.10 (Edwards Lifesciences LLC, Irvine, CA, USA), compared with CO measurements obtained by bolus thermodilution by pulmonary artery catheterization (PAC) in the intensive care setting. ⋯ Our data show a poor level of concordance between measures provided by the two methods. We found an underestimation of CO values measured with the 1.07 software version of FloTrac for supranormal values of CO. The new software (1.10) has been improved in order to correct this bias; however, its reliability is still poor. On the basis of our data, we can therefore conclude that both software versions of FloTrac/Vigileo did not still provide reliable estimation of CO in our intensive care unit setting.

This project was devised to estimate the incidence of major complications of airway management during anaesthesia in the UK and to study these events. ⋯ Although these data suggest the incidence of death and brain damage from airway management during general anaesthesia is low, statistical analysis of the distribution of reports suggests as few as 25% of relevant incidents may have been reported. It therefore provides an indication of the lower limit for incidence of such complications. The review of airway management indicates that in a majority of cases, there is 'room for improvement'.

ICU fire evacuation preparedness in London: a cross-sectional study.
Hospital fires present a sporadic but significant threat to patients and staff. This is especially so within an intensive care unit (ICU) setting, due to the complexity of moving acutely unwell patients reliant on invasive monitoring and organ support. Despite an average of 500 in-hospital fires reported to the UK department of health per annum, causing 65 injuries and 1-2 fatalities, the readiness of ICUs for urgent evacuation has not been assessed. ⋯ Forward planning for an urgent evacuation can be improved.

During ultrasound (US)-guided cannulation of the subclavian vein (SCV) via an infraclavicular route, the view of the needle behind the clavicle may be obscured. This study describes the US-guided supraclavicular cannulation of the brachiocephalic vein (BCV). ⋯ This US-guided method offers a new possibility for central venous line placement in small children. It provides good needle guidance without any disturbing US shadow caused by bony structures.

Randomized Controlled Trial
Continuous care and empathic anaesthesiologist attitude in the preoperative period: impact on patient anxiety and satisfaction.
Continuous care (one anaesthesiologist per patient) and anaesthesiologist empathy at the preoperative visit could affect patient anxiety and satisfaction. We tested both unproven issues in a population at increased risk of anxiety and dissatisfaction. ⋯ The 'one patient, one anaesthesiologist' model, in addition to ensuring sufficient time for open discussion and questions at the preoperative visit, improved patient satisfaction.
