BACKGROUND Hemodynamic optimization improves postoperative outcomes in high-risk surgery patients. The monitoring of cardiac output (CO) and dynamic parameters of fluid responsiveness can guide hemodynamic optimization. We conducted a survey to assess the current hemodynamic monitoring and management practices of Korean anesthesiologists during high-risk surgery. METHODS E-mails containing a ...

a b s t r a c t a 36-year-old male patient with posttraumatic cervical cord damage and resultant quadriparesis, demonstrated hypotension and periods of bradycardia. for most of his two-month stay in the intensive care unit (icu), he was dependent on dopamine support to maintain hemodynamic stability. keeping in mind evidence from the literature, that electrostimulation of acupoints neiguan (pc ...

Although rotational parameters by speckle tracking echocardiography (STE) have been previously compared to sonomicrometry and cardiac magnetic resonance imaging, few have examined the relationship between left ventricular (LV) rotational mechanics and intraventricular measures of load-independent contractility, LV stiffness, or ventriculoarterial coupling. The aim of this study was to compare t...

In this study we evaluated, in 10 sevoflurane-anesthetized pigs undergoing abdominal surgery, different techniques for measuring autonomic nervous system (ANS) activity: ANSiscope index, spectral analysis of heart-rate variability, hemodynamic variables, and plasma catecholamines and cortisol levels. Animals underwent a 120-min anesthesia during which unilateral ovariectomy was performed. Cardi...

BACKGROUND Hemodynamic control was compared in patients with mild cognitive impairment (MCI) or mild Alzheimer's dementia (AD) as well as in healthy elderly subjects. METHODS Noninvasive, continuous hemodynamic recordings were obtained from 14 patients and 48 controls during supine rest (tilt of 30 and 70°). Cardiac output, end-diastolic volume, total peripheral resistance, heart rate variabi...

OBJECTIVE Acute lung injury still accounts for postoperative mortality after cardiopulmonary bypass (CPB). The safety and the efficacy of pulsatile pulmonary perfusion (PPP) during CPB were analyzed. Preliminary results of the first PPP trial in human beings are reported. METHODS Thirty low-risk coronary artery bypass grafting (CABG) patients were prospectively randomized to receive PPP with ...

RATIONALE Circulatory failure, especially with low systemic vascular resistance (SVR), as observed in septic shock, thyrotoxicosis, and anemia, is a particular pattern that should suggest thiamine (vitamin B1) deficiency. The clinical picture of wet beriberi secondary to thiamine deficiency only demonstrates non-specific clinical manifestations. For a diagnosis of wet beriberi, medical history ...

OBJECTIVES This study sought to evaluate whether supra-aortic angiography during preparatory balloon aortic valvuloplasty (BAV) improves valve sizing. BACKGROUND Current recommendations for valve size selection are based on annular measurements by transesophageal echocardiography and computed tomography, but paravalvular aortic regurgitation (PAR) is a frequent problem. METHODS Data of 270 ...

Purpose: to study the effect of an identical training process on functional state high-level sprint swimmers both genders.
 Material and methods. The heart rate variability indices, central hemodynamic parameters PWC170/kg measurements were compared between 86 male 42 female with sports qualifications from first-class athlete Master Sports International Class, separately, – 38 males 9 fema...

BACKGROUND AND PURPOSE Perfusion imaging with dynamic susceptibility contrast MR imaging (DSC-MRI) has been used to evaluate hemodynamic status in patients with symptomatic occlusive cerebrovascular disease. The aim of the present study was to determine the hemodynamic changes occurring in asymptomatic patients with unilateral internal carotid artery (ICA) occlusion by use of DSC-MRI with trans...
