We studied the significance of near-infrared spectroscopy (NIRS), for measuring tissue oxygenation (S(t)O(2)) and perfusion adequacy, and thus for haemodynamic monitoring of patients after cardiac surgery. We compared NIRS-derived S(t)O(2) of the thenar muscle to haemodynamic variables, oxygenation indices, temperature, lactate levels and urinary output, in 23 patients in the ...

OBJECTIVES: To determine the acute hemodynamic effect of moderate doses of nebivolol (vasodilating beta1-selective blocker) vs. metoprolol tartrate (non-vasodilating beta1-selective blocker) in systolic heart failure (SHF). MATERIAL AND METHODS: 20 stable patients with SHF (left ventricular (LV) ejection fraction < or = 35%) underwent right heart catheterization. Once a reproducible ...

BACKGROUND AND OBJECTIVE: Evaluation of hemodynamics in patients with acute myocardial infarction is crucial. In clinical practice, the comparison of a new measurement technique with an established one is often needed to see whether they agree sufficiently for the new to replace the old. Such investigations are often analyzed inappropriately, ...

OBJECTIVE: To first report the successful use of the new inodilator levosimendan in a premature infant with congestive heart failure (CHF) following cardiac surgery. Although the calcium sensitizer levosimendan improves hemodynamics in adults with CHF, no data are available on the use of levosimendan in premature infants with CHF. DESIGN: ...

Early detection of asymptomatic left ventricular systolic dysfunction (LVSD) is beneficial in managing heart failure. Recent studies have cast doubt on the usefulness of cardiac output as an indicator of LVSD. In impedance cardiography (ICG), the dZ/dt waveform has a systolic wave called the E wave. This study looked at ...

The arteriovenous fistula used for vascular access for hemodialysis may contribute to development of congestive heart failure. Theses patients can present with frequent episodes of congestive hear failure. Traditional management of high-inflow, a high-cardiac-output fistula generally involves either closure or banding. Although high-output state can be controlled, the lifeline of ...

In this paper we present a study of measuring the cardiac output at patients with implanted pacemakers. The cardiac output is measured with respect to the atrio-ventricular delay. We have scored the maximum relative cardiac output for each patient. For the measurement we have used a home made digital bioimpedance ...

Transhiatal resection for carcinoma of the distal esophagus is associated with relative high morbidity and mortality. We present a rare case of cardiac tamponade after transhiatal esophagectomy for which emergency sternotomy was performed. Probably the retraction of the heart during exploration of the mediastinum caused a laceration of an epicardial ...

INTRODUCTION AND AIM: Cardiac index remains an important measured variable used to optimise fluid and haemodynamic support in the postoperative cardiac setting. Recent developments in non-invasive continuous wave Doppler devices enable rapid assessment of cardiac index with decreased morbidity. This study aimed to determine the clinical utility of one such ...

As outlined in Table 1, the nonthermodilution techniques available to measure cardiac output are noninvasive and clinically applicable to a variable degree. The truly noninvasive monitors are bioimpedance and CO2 re-breathing. The latter, however, requires the patient to be intubated, and the former continues to be evaluated with regard to ...

The most frequent pericardial emergency is cardiac tamponade, but complications of an acute coronary syndrome and aortic dissection may also involve the pericardium. Acute pericarditis can also represent a medical emergency due to chest pain of upsetting intensity. Decompensations in chronic advanced constriction and in the clinical course of purulent ...

Visceral leishmaniasis (VL) is endemic in many countries worldwide, including India. Globally, sodium stibogluconate (Sb) remains the cornerstone of therapy, except in some parts of India owing to increasing drug resistance. Although electrocardiographic changes associated with Sb therapy have been described, global cardiac function using tools such as colour Doppler ...

OBJECTIVE: Percutaneous catheter drainage (PCD) is not always effective in a case of hemopericardium. Acute occlusion of catheter and cardiac perforation can happen more often. To perform subxiphoid pericardiotomy within a minute for emergency cases, we have done this procedure in a blind method after finger dissection by subxiphoid approach. ...

Pulmonary hypertension (PH) is a progressive, fatal pulmonary circulatory disease that accompanies many conditions (including left to right side shunt) with compensatory elevated cardiac output. PH also complicates chronic hemodialysis (HD) therapy immediately after the creation of an arteriovenous (AV) access, even before starting HD therapy. It tends to regress ...

A 27-year-old Hispanic man with a history of hypertension and end-stage renal disease for 4 years became unresponsive, apneic, and pulseless during hemodialysis. During his 4 year period on dialysis, vascular access had become increasingly difficult and ultimately a transhepatic catheter had been placed 9 months prior to this event. ...

BACKGROUND: Microwave energy is commonly used on the beating heart to create lesions for the surgical treatment of atrial fibrillation. However, lesion transmurality is likely to depend on several factors including tissue thickness and blood flow. This study was designed to determine the effect of cavitary blood flow on transmurality ...

New trends in cardiovascular monitoring use the arterial pulse as a less invasive means of assessing cardiac output. When adopting a new technology into practice, three questions need to be answered: (1) is the method technologically sound?, (2) is it based on physiologic principles?, and (3) are the applications clinically ...

This was a retrospective observational study in a pediatric intensive care unit, in which 19 patients received levosimendan. There were no adverse events attributable to levosimendan and no instances where the clinical condition worsened after administration. Arterial lactate levels decreased significantly following levosimendan administration during cardiopulmonary bypass for anticipated low ...

Cardiac tamponade is a life-threatening process that must be diagnosed and treated in a timely fashion. As blood fills the pericardial sac, right ventricular filling is impeded and cardiac output is diminished, ultimately leading to cardiovascular collapse. Fortunately, emergency ultrasonography has improved the way we manage these patients today. In ...

Sander Michael - - 2006
INTRODUCTION: Cardiac output (CO) monitoring is indicated only in selected patients. In cardiac surgical patients, perioperative haemodynamic management is often guided by CO measurement by pulmonary artery catheterisation (COPAC). Alternative strategies of CO determination have become increasingly accepted in clinical practice because the benefit of guiding therapy by data derived ...

Cardiac tamponade is an infrequent but potentially lethal complication related to use of central venous catheters (CVC). We present the case of a 16-year-old female with Diamond-Blackfan anemia (DBA) who developed pericardial tamponade secondary to superior venous caval obstruction caused by CVC thrombosis. The patient presented 3 months after line ...
