Haemodynamic changes during positive-pressure ventilation in children.

Background: Positive-pressure ventilation may alter cardiac function. Our objective was to determine with the use of impedance cardiography (ICG) whether altering airway pressure modifies the central haemodynamics in mechanically ventilated children with no pulmonary pathology. Central venous saturation (S(cv)O(2)) was measured as an indicator of tissue perfusion.

Use of impedance cardiography to monitor haemodynamic changes during laparoscopy in children.

Methods: Haemodynamic changes were measured noninvasively using impedance cardiography (ICG) in 30 ASA I children during laparoscopic varicocelectomy under general anaesthesia. After induction and intubation, mechanical ventilation was started, then pneumoperitoneum (PP) was created. During the course of anaesthesia, values of endtidal CO2 pressue (PECO2), peak inspiratory airway pressure (PIP), heart rate (HR), mean arterial blood pressure (MABP), stroke volume index (SVI), cardiac index (CI) and systemic vascular resistance index (SVRI) were recorded at 1 min intervals.

Preparation of selenium yeasts I. Preparation of selenium-enriched Saccharomyces cerevisiae.

Selenium (Se) is an essential micronutrient for human and animal organisms. Organic selenium complexes and selenium-containing amino acids are considered the most bioavailable. Under appropriate conditions yeasts are capable of accumulating large amounts of trace elements, such as selenium, and incorporating them into organic compounds.

[Use of clozapine during pregnancy].

The authors deal with the use of closapine during pregnancy. In their cases after the use of closapine during pregnancy, healthy children were born.

[Dopamine, noradrenaline and serotonin levels in amniotic fluid during the second trimester in normal and pathologic pregnancy].

Authors measured the dopamine (DA), noradrenaline (NA) and serotonin (5-HT) contents of amniotic fluid between 19 and 21 weeks with fluorimetric method. The amniotic fluid samples were obtained by transabdominal amniocenteses performed due to elevated maternal serum-alphafetoprotein levels and suspect ultrasound findings. They considered as normal values the average of 30 amniotic fluid samples obtained from pregnant women who gave birth to healthy babies at term.

The diagnostic value of maternal pregnancy-specific beta 1-glycoprotein in threatened abortion.

208 serum SP1 measurements have been made in 124 women admitted at the 8th to 20th gestational week for the treatment of threatened abortion. Pregnancy ended in abortion in 85,6 p.c.
