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)
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)
The intra- and postoperative course of 30 anaesthetics in 24 MH-carriers verified by in vitro contracture tests is reported. None of the patients received dantrolene prophylactically and only agents known to be nontriggers were used for anaesthesia. Neither MH-related changes in perioperative heart rates, body temperatures, and CK levels nor any other(More)
To clarify the contracture response to 4-chloro-m-cresol (4-CmC) in malignant hyperthermia (MH) equivocal (MHE) muscle, we studied the effect of cumulative concentrations of 4-CmC. In vitro contracture test (IVCT) was performed in 35 probands according to the European MH test protocol. Surplus muscle bundles were exposed to 4-CmC (25-200 micromol/L),(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)
We have measured the n-octanol/water distribution coefficients at 37 degrees C of two steroidal myoneural blockers (pancuronium and vecuronium) and of their 3-hydroxy metabolites over a pH range from 1.5 to 11. Pancuronium was found not to be lipid soluble. The mean distribution coefficient of 3-hydroxy vecuronium at pH = 7.4 was 0 and that of vecuronium(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)
The amounts of halothane and isoflurane trapped after exposure for up to 3 h at 2 MAC in commonly used anaesthesia circuit tubing were quantitated by gas chromatography. The decontaminating effects of procedures such as flushing with oxygen, thermal disinfection and/or routine storage were assessed in a similar way. After halothane exposure, anaesthetic(More)
