Quantitation of volatile anesthetic-induced depression of myocardial contractility using a single beat index derived from maximal ventricular power

The Sparing Effect of Low-Dose Esmolol on Sevoflurane during Laparoscopic Gynaecological Surgery

“…An increase in the concentration of volatile anaesthetic raises the risk of complications including intraoperative cardiovascular depression 1 , slow recovery 2 and postoperative respiratory depression. 3 In order to prevent these sideeffects, anaesthetists monitor the depth of the hypnotic component of anaesthesia via the bispectral index (BIS), administer adjuvants such as short-acting opioids, local anaesthetics, or α 2 -agonists (balanced anaesthesia), and minimize the inhaled concentration of volatile anaesthetics.…”

Hemodynamic Monitoring Utilizing Transesophageal Echocardiography

“…73 PWR shows great stability concerning the changes of afterload but is also highly sensitive to preloading alterations. Therefore, several authors have proposed the correction of PWR with the square of the LVEDV, 71,74 the LV end-diastolic diameter, 75 or the LVEDA. 8,71 A close relationship between LVEDV, as a marker of preload, and maximum PWR/LVEDA ratio, 2 as a measure of myocardial contractility, is shown in Figure 8.…”

Evaluation of regional work from ECG-gated SPECT images through solution of equations of continuity for fluids–mechanical cardiac work calculated using thin wall model

“…Evaluation of regional contraction work (RCW) in vivo will add valuable information for proper choice of interventional, surgical, drug and gene therapies (Zeiher et al 1987, Silvestry et al 1996, Hannan et al 2005, Lunde et al 2006, Myerburg 2008. There are several methods to assess RCW (Murphy et al 1993, Pagel et al 1993, Kanzaki et al 2004, Maniar et al 2004, Skulstad et al 2006. However, measurements have not been generally put into practice because of its complicated procedure.…”
