AbstractTo determine whether a beat-by-beat cardiovascular index (CARDEAN: cardiovascular depth of analgesia, Alpha-2 Ltd, Lyon, France) reduces the incidence of tachycardia in ASA I –III patients undergoing orthopaedic surgery. A total of 76 patients were prospectively randomized into (1) a control group or (2) the CARDEAN group, in which the nurse anaesthetist was blinded to CARDEAN application. In addition to conventional signs, an external observer instructed the nurse ana esthetist to administer sufentanil 0.1 µg kg−1 when the CARDEAN crossed a threshold ( ≥ 60). The primary outcome...

A 5-year-old-boy (weight, 17.4 kg; height, 120 cm; body surface area, 1.02m2) with pulmonary atresia, intact ventricular septum, bipartite hypoplastic right ventricle and tricuspid valve hypoplasia presented to the author's institution for pre-Fontan evaluation. The child had under gone a bi-directional Glenn procedure at one-year of age. The electrocardiogram showed a sinus rhythm, left axis deviation, and ‘ST’ depression in V1-V3 leads. The origin of the left main coronary artery was dilated in a parasternal short axis view of the aorta by transthoracic echocardiography as well as in mid-esophageal aortic sho...

The objective of our study was to assess a contribution of myocardial repolarization changes to J-wave generation in the body surface ECG and VF in a porcine acute myocardial infarction model.Methods: In 22 anesthetized pigs, myocardial ischemia was induced by occlusion of the left anterior descending coronary artery (LAD, n = 14) and right coronary artery (RCA, n = 8). Body surface ECGs were recorded simultaneously with intramyocardial unipolar electrograms led from flexible electrodes positioned across the left ventricular (LV) wall, interventricular septum (IVS), and right ventricular (RV) wall at apical, middle and bas...

COMPLEX ARRHYTHMIAS are frequent in patients with congenital heart disease, especially after pediatric cardiac surgery.1 In this critical situation, the diagnosis demands a comprehensive transthoracic electrocardiogram (ECG), as well as a multidisciplinary team integrated by pediatric surgeons, cardiologists, electrophysiologists and intensivists. In some patients, the presence of myocardial scars, or the inadequate positioning of the ECG electrodes due to drainage tubes or dressings, impairs the correct interpretation.

Purpose of review Major adverse cardiovascular and cerebrovascular events (MACCE) significantly affect the surgical outcomes. Electrocardiogram (ECG) has been a standard intraoperative monitor for 30 years. Electroencephalogram (EEG) can provide valuable information about the anesthetized state and guide anesthesia management during surgery. Whether EEG should be a standard intraoperative monitor is discussed in this review. Recent findings Deep anesthesia has been associated with postoperative delirium, especially in elderly patients. Intraoperative EEG monitoring has been demonstrated to reduce total anesthesia drug...

In this study, we examined the hemodynamic, vascular and atrial responses to M. l. lemniscatus venom. Anesthetized rats were used for hemodynamic and electrocardiogram (ECG) recordings; in vitro experiments were carried out in rat isolated thoracic aorta and atria preparations. In vivo, venom (0.1 and 0.3 mg/kg) caused immediate and persistent hypotension that was maximal within the first minute with both doses being lethal after ~40 and ~20 min, respectively. ECG, heart and respiratory rates were not altered during the transient hypotension phase induced by venom but all altered prior to death. There was no evid...

The objective of this research was to measure heart rate (beat per minutes) in pigs with technology that soon will be affordable. Affordable heart rate monitoring is done today at large scale on humans using the Photo Plethysmography (PPG) technology. We used PPG sensors on a pig′s body to test whether it allows the retrieval of a reliable heart rate signal. A continuous wavelet transform (CWT)-based algorithm is developed to decouple the cardiac pulse waves from the pig. Three different wavelets, namely second, fourth and sixth order Derivative of Gaussian (DOG), are tested. We show the results of the developed ...

This study was designed to investigate which cardiac electrophysiological conditions exaggerate QT-prolonging and arrhythmogenic effects of sevoflurane. We used the O'Hara-Rudy dynamic model to reconstruct human ventricular action potential and a pseudo-electrocardiogram, and simulated LQT1 and LQT2 phenotypes by decreasing conductances of IKs and IKr, respectively. Sevoflurane, but not propofol, prolonged ventricular action potential duration and QT interval in wild-type, LQT1 and LQT2 models. The QT-prolonging effect of sevoflurane was more profound in LQT2 than in wild-type and LQT1 models. The potent inhibitory effect ...
