The aim of this study was to determine the agreement between pulmonary artery thermodilution (PA-TD) and a new pulse contour method (PCM), FloTrac/Vigileo version 1.0, and to asses the ability of FloTrac to track sudden changes in cardiac output. ⋯ In this study, agreement between PA-TD and the PCM was poor, but the PCM was able to track the direction of pace-induced changes in cardiac output.

The analysis of perioperative cardiac arrest and mortality remains a potentially valuable method to improve clinical outcome. This survey evaluated the incidence and causes of perioperative cardiac arrests and mortality in a paediatric surgical population over 5 years. ⋯ Major risk factors for cardiac arrests were age under 1 year, poor physical status and emergency surgery. Respiratory and cardiovascular-related events accounted for most of all anaesthesia-related cardiac arrests. High ASA-PS was the leading cause of perioperative mortality.

Cardiac complications are a major cause of perioperative morbidity and mortality. These are caused by either myocardial ischaemia or acute coronary thrombosis. ⋯ This assessment allows measures to be taken that aim to reduce such risks. The present review summarizes the current state of knowledge on the preoperative assessment of the cardiac patient scheduled for noncardiac surgery.

Comparative Study
Effects of temperature gradient reduction in three different carbon dioxide absorbents.
Temperature gradients in CO2 absorbents may locally increase the water content by condensation. We hypothesized that temperature gradient reduction (TGR) would prevent increased water content, thus preserving the reactivity of the CO2 absorbent and thereby increasing its time to exhaustion (longevity). The purpose of this study was to compare the effects of TGR on the longevity of CO2 absorbent with three different types of CO2 absorbents. ⋯ TGR is a useful method to prevent local increase in water content and improve the longevity of CO2 absorbent. The effectiveness of TGR on longevity and water content changes varied in the different types of CO2 absorbent.

Anaesthetists are at increased risk of successful prosecution for manslaughter (nonculpable homicide) compared with other clinicians. ⋯ In order to reduce their legal liability and improve patient safety, junior anaesthetists must practise according to professional guidelines and seek professional training in medicolegal matters.
