BACKGROUND: Pressure-volume loops (PVL) provide vital information regarding ventricular performance and pathophysiology in cardiac disease. Unfortunately, acquisition of PVL by conductance technology is not feasible in neonates and small children due to the available human catheter size and resulting invasiveness. The aim of the study was to validate the accuracy of PVL in small hearts using volume data obtained by real-time three-dimensional echocardiography (3DE) and simultaneously acquired pressure data...

BACKGROUND: Carbon dioxide pneumoperitoneum for laparoscopic surgery increases arterial pressures, heart rate (HR), and systemic vascular resistance. In this randomized, single-blind, placebo-controlled clinical study, we investigated and compared the efficacy of esmolol and dexmedetomidine to provide perioperative hemodynamic stability in patients undergoing laparoscopic cholecystectomy. METHODS: Sixty patients, of either sex undergoing elective laparoscopic cholecystectomy, were randomly allocated into three groups containing twenty patients each...

Competitive flows syndrome result in severe regional hypoxemia when the deoxygenated flow from the native left ventricle (LV) competes with oxygenated flow from extracorporeal life support (ECLS) pump with potentially severe consequences for the cerebral and coronary circulations. Fast correction of hypoxemia could be obtained by decreasing native LV flow by infusion of a short-acting beta-blocker (esmolol). Our purpose was to retrospectively review the efficacy of esmolol in this situation and hypothesize on the potential mechanisms of action and the associated risks...

We report a male newborn who became symptomatic with supraventricular tachycardia on the first day of life. Neither adenosine nor electric cardioversion could terminate the tachycardia, therefore intravenous esmolol (β-receptor blocker) was initiated. Inspite of subsequent administration of various antiarrhythmic medications in increasingly higher doses, repeated supraventricular tachycardic episodes occurred. The electrocardiogram showed typical findings of a multifocal atrial tachycardia as the underlying cause...

Esmolol produces early regression of left ventricular hypertrophy and improves coronary artery remodeling, although the impact of short-term treatment with this beta-blocker on remodeling in large arteries has not yet been studied. We hypothesized that even a short (48h) course of esmolol might alter remodeling of the aorta in the spontaneously hypertensive rat (SHR). Fourteen-month-old male SHRs were treated intravenously with vehicle (SHR, n=8) or esmolol (SHR-E, n=8) (300μg/kg/min). Age-matched, vehicle-treated male Wistar-Kyoto rats (WKY, n=8) served as controls...

BACKGROUND AND AIMS: Most vital aspect of Endoscopic Sinus Surgery (ESS) is an optimal visibility in the surgical field. This invariably requires controlled hypotension to facilitate surgical dissection and to decrease operative time. We used esmolol and magnesium sulfate to achieve controlled hypotension and assessed the quality of the surgical field in ESS. MATERIAL AND METHODS: A total of 30 patients undergoing ESS, were enrolled in three parallel groups of 10 patients each in a prospective randomized double-blind study...

AIMS: This study aimed to evaluate the effects of esmolol treatment for patients with refractory ventricular fibrillation (RVF) in out-of-hospital cardiac arrest (OHCA). METHODS: This single-centre retrospective pre-post study evaluated patients who were treated between January 2012 and December 2015. Some patients had received esmolol (loading dose: 500μg/kg, infusion: 0-100μg/kg/min) for RVF (≥3 defibrillation attempts), after obtaining consent from the patient's guardian...

Blockage of β1-adrenergic receptors is one of the most effective treatments in cardiovascular medicine. Esmolol was introduced some three decades ago as a short-acting β1-selective antagonist. Landiolol is a more recent addition. Here we compared the two compounds for their selectivity for β1-adrenergic receptors over β2-adrenergic receptors, partial agonistic activity, signaling bias, and pharmacochaperoning action by using human embryonic kidney (HEK)293 cell lines, which heterologously express each human receptor subtype...

BACKGROUND: Previous studies have suggested that β1-receptor blockers benefit septic shock patients. This study aimed to determine whether β1-receptor blockers benefit tissue perfusion in sepsis and to identify parameters to reduce the risk of this drug in sepsis. METHODS: Consecutive septic shock patients were recruited from the Intensive Care Unit of Peking Union Medical College Hospital within 48 h of diagnosis. All patients were hemodynamically stable and satisfactorily sedated with a heart rate (HR) ≥100 beats/min...

The incidence of ST segment elevation myocardial infarction (STEMI) has decreased over the last two decades in developed countries, but mortality from STEMI despite widespread access to reperfusion therapy is still substantial as is the development of heart failure, particularly among an expanding older population. In developing countries, the incidence of STEMI is increasing and interventional reperfusion is often not available. We here review the pathophysiology of acute myocardial infarction and reperfusion, notably the temporal and spatial evolution of ischaemic and reperfusion injury, the different modes of cell death, and the resulting coronary microvascular dysfunction...

The present study reports a case of electrical storm occurring in a 43-year-old woman with dilated cardiomyopathy. The patient suffered from a cardiac electrical storm, with 98 episodes of ventricular tachycardia rapidly degenerating to ventricular fibrillation in hospital. The patient was converted with a total of 120 defibrillations. Recurrent ventricular tachycardia/fibrillation was initiated by premature ventricular beats. The patient did not respond to the use of amiodaronum. However, the administration of esmolol stabilized the patient's heart rhythm...

PURPOSE OF REVIEW: The article reviews the recent evidence on the anesthetic management of patients undergoing craniotomy for supratentorial tumor resection. RECENT FINDINGS: A rapid recovery of neurological function after craniotomy for supratentorial tumor allows for the prompt diagnosis of intracranial complications and possibly an early hospital discharge. Intraoperative esmolol infusion was shown to reduce the anesthetic requirements, and may facilitate a more rapid recovery of neurological function...

BACKGROUND AND AIM: Induced hypotension limits intra-operative blood loss to provide better visibility of the surgical field and diminishes the incidence of major complications during functional endoscopic sinus surgery (FESS). We aimed at comparing nitroglycerine, esmolol and dexmedetomidine for inducing controlled hypotension in patients undergoing FESS. MATERIAL AND METHODS: One hundred and fifty American Society of Anesthesiologists physical status I or II adult patients undergoing FESS under general anesthesia were randomly allocated to three groups of 50 patients each...

BACKGROUND: Recent studies suggest that beta-adrenergic blockers attenuate systemic inflammation and improve survival in sepsis. We investigated whether esmolol can reduce lung injury and modulate inflammatory response in a rat model of severe acute pancreatitis (SAP). METHODS: A taurocholate-induced SAP was used, with or without continuously intravenous pumping of esmolol (15 mg/kg/h). Heart rate and arterial pressure were monitored. Nine hrs after esmolol administration, blood was drawn for blood gas analyses and cytokine (interleukin(IL)-6, tumor necrosis factor (TNF)-α) detections, lungs and pancreata were isolated for measurements of myeloperoxidase (MPO) activity and histological damage...
