Randomized Controlled Trial Comparative Study
Comparison of transversus abdominis plane block vs spinal morphine for pain relief after Caesarean section.
Transversus abdominis plane (TAP) block is an alternative to spinal morphine for analgesia after Caesarean section but there are few data on its comparative efficacy. We compared the analgesic efficacy of the TAP block with and without spinal morphine after Caesarean section in a prospective, randomized, double-blinded placebo-controlled trial. ⋯ Spinal morphine-but not TAP block-improved analgesia after Caesarean section. The addition of TAP block with bupivacaine 2 mg kg(-1) to spinal morphine did not further improve analgesia.

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'.

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.

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.
