Erste Erfahrungen mit einem neuen Therapiekonzept für die Schrittmacherbehandlung von Säuglingen und Kleinkindern
1998
Fragestellung: Fur Sauglinge und Fruhgeborene ist eine geringe Grose des Schrittmacheraggregats besonders wichtig. Unsere bisherigen Erfahrungen mit dem kleinsten, z.Z. verfugbaren Pulsgenerator bei Kindern wurden analysiert und hier vorgestellt. Methode: Bei 2 Fruhgeborenen mit symptomatischem kompletten AV-Block und einem 8jahrigen Patienten mit kongenitalem AV-Block bei komplexen Vitium und Palliation mittels totaler kavopulmonaler Anastomose wurde der kleinste z.Z. verfugbare Pulsgenerator erstmals mit bipolaren, epikardialen steroideluierenden Elektroden implantiert. Dieser Schrittmacher arbeitet durch den Autocapture-Algorithmus besonders energiesparend, so das trotz geringerer Batter…
Reduced inotropic support after aprotinin therapy during pediatric cardiac operations
1999
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.We conducted a randomized, double-blind, placebo-controlled trial in 34 infants (mean age, 2.5 years) who had cardiac operations. Half of the patients received high-dose aprotinin therapy. There were no significant differences between the aprotinin and placebo groups with respect to age, weight, sex, aortic cross-clamp time, and CPB time. The following data were recorded at arrival in the intensive care unit 6, 12, 24, and 48 hours after termination of CPB: heart rate, bloo…
Evaluation of the pulse wave arrival time as a marker for blood pressure changes in critically ill infants and children
1995
Objective. Pulse arrival time (PAT), which is the interval between the R wave of the electrocardiogram (ECG) and the arrival of the pulse wave peripherally, has been reported to be suitable for use as an indirect measure of blood pressure change. The purpose of this study was to evaluate, in critically ill infants and children, the degree to which 1/PAT covaries with systolic, diastolic, and mean blood pressure, as well as heart rate.Methods. A laboratory device was used to calculate PAT in real time from the ECG and the plethysmographic curve of pulse oximetry used for routine monitoring. Calculated PAT and corresponding blood pressures and heart rate were stored on hard disk. A total of 1…
Changes in lymphocyte subsets after cardiac surgery in children.
2001
Children undergoing cardiopulmonary bypass (CPB) operations have an increased risk of developing severe infections. Impairment of the immune system may contribute to the development of sequelae such as capillary leaks, pulmonary dysfunction and auto-immune reactions. The objective of this study was to investigate the impact of cardiac surgery with CPB on the immune system of infants and young children. We conducted a prospective study to investigate the changes in circulating lymphocyte subpopulations in a sample of 21 consecutive infants and young children undergoing cardiac surgery for congenital heart disease. The following statistically significant (P<0.05) results were obtained: leucoc…
Evaluation of gastric intramucosal pH during and after pediatric cardiac surgery.
1997
Objectives: In adult patients, intramucosal pH (pHi) has been advocated to detect postoperative complications. The purpose of our study was to evaluate this technique in pediatric patients during and after cardiac surgery. Methods: Thirty-five infants (age: 5 days to 15 years, median 1.8 years; and weight: 3.2‐32 kg, median 9.8 kg) were studied. pHi was measured before cardiopulmonary bypass (CPB), after 30 min of CPB, prior to weaning off CPB, at intensive care unit arrival, and 6, 12, 24, 48 and 72 h after surgery. Results: There were no complications related to the tonometer. A pathologically low pHiB 7.32 was found during surgery in less than 17%, at intensive care unit arrival in 83% a…
