OBJECTIVE To obtain normal M mode (one dimensional) echocardiographic values in a substantial sample of normal infants and children. DESIGN Data were obtained over three years from a single centre in central Europe. PATIENTS 2036 healthy infants and children aged one day to 18 years. METHODS In line with recommendations for standardising measurements(More)
During the past decade new techniques such as computed tomography (CT) and ultrasonography have been reported to have changed the diagnostic investigation and treatment of renal abscess in adults. To evaluate whether similar changes have taken place in the pediatric age group, a retrospective study of all patients seen between 1979 and 1989 was performed.(More)
OBJECTIVE To evaluate the hemodynamic effects of tolazoline and prostacyclin in infants with pulmonary vasospasm after cardiac surgery. DESIGN Prospective cohort study. SETTING Pediatric ICU. PATIENTS The cohort consisted of 42 infants and children with congenital heart disease and pulmonary hypertension who underwent corrective surgery and were(More)
BACKGROUND Several reports indicate that aprotinin treatment before and during cardiopulmonary bypass (CPB) might have a protective effect on the myocardium. We evaluated the hemodynamic effects of perioperative aprotinin treatment. METHODS We conducted a randomized, double-blind, placebo-controlled trial in 34 infants (mean age, 2.5 years) who had(More)
OBJECTIVE To compare cardiac output measurements in critically ill infants by the dual beam Doppler and thermodilution techniques. DESIGN Prospective direct comparison of the two techniques. For statistical evaluation one randomly assigned paired measurement of every patient was used. SETTING Paediatric intensive care unit in a university hospital. (More)
Pulmonary air leaks are one of the most common problems in patients with the adult respiratory distress syndrome, ARDS. We report what we believe to be the first case in which unilateral high-frequency ventilation combined with contralateral conventional positive pressure ventilation has been used successfully to manage severe air leak in an infant with(More)
During the last years, noninvasive determination of the aortic valve area by Doppler echocardiography using the continuity equation became popular. However, a systematic valve area underestimation of about 15% compared to invasive measurements using the Gorlin formula has been reported. The cause therefore is unknown. The purpose of this study was to(More)
Abstract Background. It has been suggested that tungsten coils (TCs) may corrode 30 months after transcatheter embolisation (TCE). The aim of this study was to follow up children after TCE of aorto-pulmonary collaterals (APCs) with TCs. Materials and methods. Successful TCE of 99 APCs was performed in children using 152 TCs. Chest radiographs were obtained(More)
In patients with VSD right ventricular pressure can be determined noninvasivly by subtracting the VSD-gradient from the systolic blood pressure. Using a stand-alone continuous-wave Doppler the VSD-gradient may be underestimated due to a large angle theta caused by the various VSD locations and the often atypical VSD-jet directions. Therefore Color-Doppler(More)
Children undergoing cardiac surgery are at additional risk for postoperative low cardiac output syndrome (LCOS). Anticipation of the syndrome from preoperative hemodynamic condition, surgical procedure, and adverse intraoperative events is a key to successful postoperative management. Inotropic support is primarily based on catecholamines. However,(More)
