Anaesthesia
-
The aim of this study was to investigate cardiac function and haemodynamic indices using transthoracic echocardiography in women with severe pre-eclampsia who had already received treatment interventions. Fifteen women with treated severe pre-eclampsia were studied using transthoracic echocardiography. Mean (SD) cardiac output in women with treated disease was 5690 (1708) ml.min(-1). ⋯ Left ventricular mass was increased at 182.0 (44.4) g. There was large variability in haemodynamics in women with treated severe pre-eclampsia. Transthoracic echocardiography is acceptable and applicable and enables quantification of cardiac function in women with severe pre-eclampsia.

Randomized Controlled Trial
Induction of general anaesthesia by effect-site target-controlled infusion of propofol: influence of pharmacokinetic model and ke0 value.
We studied the use of a new ke0 value (0.6 min(-1)) for the Marsh pharmacokinetic model for propofol. Speed of induction and side-effects produced were compared with three other target-controlled infusion systems. ⋯ The Schnider model in effect-site control produced induction times that were longer (298 (282-398 [58-513])s) than those observed with the Marsh model in blood control (p < 0.05), or either effect-site control mode (p < 0.001). There were no differences in the magnitude of blood pressure changes or frequency of apnoea between groups.
