OBJECTIVE To investigate the relation between the severity of pulmonary hypertension and the outcome of medical treatment. METHODS 98 patients with primary pulmonary hypertension--nine (6%) with systemic disease and pulmonary hypertension and 39 (27%) with thromboembolic pulmonary hypertension--received medical treatment and were followed between 1982 and 1995. They were given long term intra...

Hydralazine was administered to eight patients (mean age, 69 +/- 2 years) who had stable, advanced chronic obstructive pulmonary disease (COPD), pulmonary arterial hypertension (mean pulmonary arterial pressure, 31 +/- 3 mm Hg), and cor pulmonale. All of the patients were studied at rest and during exercise. After intravenous administration of hydralazine at rest, there were statistically signi...

Background and Aim: The clinical applicability of substitution of central venous oxygen saturation for mixed venous oxygen saturations in monitoring global tissue hypoxia is still a matter of controversy. Hence aim of the study is comparison of paired samples of mixed venous and central venous oxygen saturation and comparison in relation to cardiac index in varying hemodynamic conditio s. Mater...

Cardiopulmonary bypass (CPB) in neonates and infants routinely employs lower blood flow rates (BFR), temperatures, and hematocrits (Hct) than those typically observed in adult CPB. The purpose of this study was to evaluate the accuracy of three devices available for continuous in-line measurement of venous oxygen saturation (SvO2) and Hct during pediatric CPB. Venous blood samples were obtained...

The objective of this study was to evaluate the effect of hypothermic cardiopulmonary bypass (CPB) on cerebral oxygen saturation (rSO2), internal jugular bulb venous oxygen saturation (SjvO2), mixed venous oxygen saturation (SvO2), and bispectral index (BIS) used to monitor cerebral oxygen balance in pediatric patients.Sixty American Society of Anesthesiologists Class II-III patients aged 1 to ...

CONTEXT Coronary artery bypass graft (CABG) surgery is a common procedure for patients with coronary artery disease. The physiologic effects of postoperative osteopathic manipulative treatment (OMT) following CABG have not been documented previously. OBJECTIVE To determine the effects of OMT on cardiac hemodynamics post-CABG surgery. DESIGN Pilot prospective clinical study (N=29). SETTING...

Background Central (ScVO2) and mixed venous oxygen saturation (SvO2) and blood lactate are useful measurement tools for evaluating the degree of hypoperfusion in patients with different disease processes. The aim was to study incidence of both low as well as high ScvO2 and assessed their relationship to markers of tissue hypoxia, course and outcome in patients undergoing elective cardiac surgery.

UNLABELLED beta-Adrenergic receptors are involved in altering cerebral metabolism and blood flow. This study was performed to determine whether propranolol would alter the microregional O2 balance in the brain. Rats were anesthetized with 1.4% isoflurane. Isotonic sodium chloride solution (control group), propranolol 2 mg/kg (low propranolol group) or propranolol 20 mg/kg (high propranolol grou...
