No significant alterations of serotonin or glutamate were observed over the 2 h period for the healthy subjects. Technical problems were detected in 18 (15%) of the 122 microdialysis catheters implanted and were more frequent during the initial period of using microdialysis in our unit. In four patients (3% of implanted catheters), follow-up computed tomography (CT) scans showed a small intracerebral blood collection (always

av E Diczfalusy · 2012 — In this thesis, the maximum tissue volume of influence (TVImax) for a microdialysis catheter was simulated and evaluated using the finite element method (FEM), The fluid is pumped through the 71 High Cut off Brain catheter during microdialysis in brain tissue.

Introduction Cerebral microdialysis involves placement of a small catheter with a semipermeable membrane in the parenchyma of the brain, so that a dialysate fluid can be instilled into the catheter, allowed to equilibrate and withdrawn for analysis (Figure 20-1).

Lactate Threshold Test with Senzimes On-Line Lactate

The probe tip is placed into biological tissue and perfused via an inlet tube with fluid isotonic to the tissue interstitium.

The nurses at the critical care department, pediatric critical care department, transplant The microdialysis catheter was fixed on the leg with tape. The microdialysis catheter’s inlet tube was connected to a microdialysis pump. The outlet tube ended with a microvial holder where the sample was collected into small microvials. CMA 7 PROBES FOR LARGE MOLECULES! Ideal for use in small areas of the brain or spinal cord of small animals. It is especially suitable for studies in transgenic mice.

CONCLUSION: Microdialysis catheters with high cut-off membranes can be used in routine clinical practice in the NSICU, adding the possibility of macro-molecule sampling from the extracellular space during monitoring. In clinical practice the most commonly used system comprises a catheter that is 10 mm in length with a 20-kDa (CMA 70, CMA Microdialysis, Solna, Sweden) or 100-kDa (CMA 71, CMA Microdialysis, Solna, Sweden) molecular weight cutoff, perfused with commercially available physiologic perfusion fluid (Perfusion Fluid CNS, CMA Microdialysis, Solna, Sweden) at a rate of 0.3 µL/min. Commonly measured Microdialysis is still a research tool but one that we are likely to hear more about in the future. To perform microdialysis a fine catheter lined with a dialysis membrane is placed into the cerebral cortex. A number of metabolites can be measured such as glucose, lactate, pyruvate, and glutamate. The microdialysate fluid is analyzed hourly.
