INTRODUCTION AND OBJECTIVES The effect of obesity on cardiac function is still under discussion. The objective of this study was to assess cardiopulmonary capacity in morbidly obese patients. Patients and method. A symptom-limited cardiopulmonary exercise stress test was carried out in 31 morbidly obese patients (BMI 50 9 kg/m2) and 30 normal controls (BMI 24 2 kg/m2. Cardiovascular function wa...

BACKGROUND Pulmonary dysfunction is one of the most common manifestations of inflammatory response after cardiopulmonary bypass (CPB). OBJECTIVE This prospective randomized study was conducted to evaluate the effect of a modified ultrafiltration (MUF) technique on pulmonary function after CPB in children. METHODS Forty patients weighing from 5 to 10 kg with congenital heart disease who requ...

PURPOSE Idiopathic scoliosis is a structural lateral curvature of the spine of unknown etiology. The relationship between degree of spine curvature and cardiopulmonary function has not yet been investigated. The purpose of this study was to determine the association between scoliosis and cardiopulmonary characteristics. METHODS Ninety children who underwent preoperative pulmonary or cardiac e...

OBJECTIVE Cardiopulmonary bypass (CPB) is associated with thyroid hormone changes consistent with euthyroid sick syndrome. Similar changes have been observed after general surgical operations. Thyroid hormone changes and their association with global oxygen consumption were studied in low-risk patients undergoing coronary artery bypass grafting (CABG) with and without CPB. METHODS Fifty-two p...

RATIONALE The role of the patent ductus arteriosus in the development of chronic lung disease in surfactant-treated premature newborns remains unclear. OBJECTIVE To examine the effects of ductus ligation on cardiopulmonary function and lung histopathology in premature primates. METHODS Baboons were delivered at 125 d, (term = 185 d) treated with surfactant, and ventilated for 14 d. Serial e...

conclusions our study showed superiority of off-pump cabg regarding lvef, rvef and valves regurgitations. future studies with prospective structure, accurate randomization, longer follow up duration, and larger sample size are needed. results one hundred eighteen patients with the mean age of 59.47 ± 9.68 years were included (81 male and 37 female). on-pump cabg was done on 84 patients and off-...

conclusions the survival rate after in-hospital cpr was very low. the duration of cpr and the time of initiating cpr effects patients’ outcomes. these findings highlight the crucial role of an organized, skilled, well-established and timely cpr team. background despite several studies, there is no agreement on factors that affect survival after in-hospital cardiopulmonary resuscitation (cpr). o...

OBJECTIVES To determine the association between gastric intramucosal pH, a minimally invasive marker reflecting the adequacy of oxygen delivery to the gastrointestinal tract, and splanchnic endotoxin, antibody to endotoxin, and tumor necrosis factor (TNF)-alpha concentrations in patients undergoing cardiopulmonary bypass. DESIGN Single-arm, prospective study. SETTING University hospital. ...
