Effects of different concentrations of desflurane on the index of cardiac electrophysiological balance in gynecologic surgery patients.

The objectives were to observe the effects of different concentrations of desflurane on QT, QTc, Tp-e, Tp-e/QT, and the index of cardiac electrophysiological balance (iCEB). Sixty patients were randomly divided into group D, group D, and group D by using a random number table, 20 in each group. After entering the operating room, patients received 10 mL/kg hydroxyethyl starch, 0.

Sevoflurane Alleviates Reperfusion Arrhythmia by Ameliorating TDR and MAPD in Isolated Rat Hearts after Ischemia-Reperfusion.

Objective: To investigate the effect of sevoflurane on the monophasic action potentials (MAPs) in isolated rat hearts after ischemia-reperfusion.

Methods: Twenty-four healthy SD male rats, weighing 280-320 g, were randomly divided into three groups after successful preparation of a Langendorff isolated heart perfusion model with a stabilization period perfusion of 15 min with Krebs-Henseleit (K-H) fluid ( = 8): the control group (group A, continuously perfused with K-H fluid for 105 min), the ischemia-reperfusion group (group B, continuously perfused with K-H fluid for 15 min, and then exposed to 60 min of global ischemia induced by Thomas solution followed by 30 min of reperfusion), and the sevoflurane group (group C, K-H fluid contained 1.0 MAC sevoflurane, and other procedures were same as in group B).

A Comparison of the Effect of Sevoflurane and Propofol on Ventricular Repolarisation after Preoperative Cefuroxime Infusion.

The aim of this study is to investigate the changes in QT, QTc, and Tp-e intervals and Tp-e/QT ratio on surface electrocardiogram (ECG) signals during anaesthesia induction using propofol or sevoflurane after preoperative cefuroxime infusion. Some 120 cases of gynaecological patients are randomly divided into propofol (P) and sevoflurane (S) groups (n=60). After cefuroxime (1.
