The effects of half the tidal volume during cardiopulmonary resuscitation (CPR) on haemodynamics, acid-base balance, and oxygenation were studied in anaesthetized pigs. The animals were ventilated with a mean tidal volume of 12.5 +/- 0.5 ml/kg at a rate of 14/minute resulting in a mean arterial pCO2 of 40 +/- 3 mmHg. They were randomly assigned to two(More)
In a randomised study comprising 16 patients undergoing vascular surgery of the lower extremities blood replacement was performed after preinfusion of either 500 ml 10% hydroxyethylstarch (LMW-HES) or 10% dextran 40 (followed by dextran 60 intraoperatively). After infusion of 500 ml within 30 min preoperatively there was a significant rise in PCWP, PAP, RAP(More)
A method has been developed for blood-brain barrier disruption to provide reproducible access to the cerebrospinal fluid of the cerebello-medullary cistern. The technique was used successfully to investigate transfer of pancuronium to the cerebral CSF compartment in pigs. After osmotic disruption of the blood-brain barrier, pancuronium concentrations(More)
The surface properties of the amniotic fluid were determined in 96 normal pregnancies between weeks 23 and 41. The y-max, y-min, hysteresis areaa, and stability index were used as parameters for evaluation of the surface tension are diagrams. These results were plotted against the gestation week and a curve for the normal course of surface tension of the(More)
Muscle biopsy and in vitro contracture tests for diagnosis of susceptibility to malignant hyperthermia (MH) were performed in two patients who had developed fever and severe myolysis during exercise. MH susceptibility was confirmed in one patient, but in the other, exercise-induced heat stroke proved to be the correct diagnosis. Clinical presentation and(More)
We investigated the effect of large volume replacement with balanced electrolyte solutions on extravascular lung water (EVLW) in 16 adult surgical patients with sepsis syndrome. Patients entered the study within the 24 h period following surgical interventions for acute necrotizing pancreatitis, intra-abdominal abscesses, and/or peritonitis. Sequential(More)
Urinary catecholamine excretion and thyroid hormone blood level were studied in 16 patients following severe cerebral trauma. Increased excretion rates of epinephrine and norepinephrine were found. There was no significant difference in the catecholamine excretion when compared with generally traumatized patients. The relationships between catecholamine(More)
Using two-dimensional and M-mode echocardiography, mitral valve function was assessed during mechanical cardiopulmonary resuscitation (CPR). In 10 anesthetized pigs CPR began 1 min after induction of ventricular fibrillation; in all pigs three different compressive forces (200, 350, and 500 Newton [N]) were applied in randomized sequence for 3 min each,(More)
