Microdialysis is a minimally-invasive sampling technique that is used for continuous measurement of free, unbound analyte concentrations in the extracellular fluid of virtually any tissue. Analytes may include endogenous molecules to assess their biochemical functions in the body, or exogenous compounds to determine their distribution within the body. The microdialysis technique requires the insertion of a small microdialysis catheter into the tissue of interest. The microdialysis

The use of microdialysis for the monitoring of digestive organs will be revised and intestinal Hence, the measurement of intestinal permeability has been used as a Research based on microcirculation and secretion during shock has

Microdialysis is increasingly being used to monitor cerebral metabolism clinically in patients with traumatic brain injury, 31 and techniques have been adapted to measure drug concentrations of putative neuroactive drugs in individuals requiring neurosurgery. 20 As more human microdialysis data are generated, intraspecies differences in drug distribution in CNS compartments as well as effects Microdialysis gives you a preview of what goes on in tissues, before chemical events can be reﬂected as changes in systemic blood levels. The microdialysis probe is designed to mimic a blood capillary and by keeping this metaphor in mind, it is easy to conceive of the many ways you can use this technique. Microdialysis was used to measure the free (or unbound) ﬂuconazole concentration in subcutaneous-tissue ISF. The principles and details of microdialysis have been described previously (17). In this study, a microdialysis probe (CMA 60; Microdialysis AB, Stockholm, Sweden) withamolecular-masscutoffof20kDa,anouterdiameterof0.6mm,and Objectives The pharmacokinetic profile of antibiotics at the site of anti‐infective action is one of the most important determinants of drug response, since it correlates with antimicrobial effect. Evaluation of gatifloxacin penetration into skeletal muscle and lung by microdialysis in rats.

Patients and methods The lung penetration of a combination of piperacillin and tazobactam, substances with low protein binding, was determined in five patients suffering from pneumonia and metapneumonic pleural empyema.

for the first time that closed chest microdialysis of the human lung is a feasible and safe method to measure lung concentrations in patients in vivo. The present data also corroborate the use of cef-pirome as a valuable agent in the treatment of lung infections with most extracellular bacteria. Keywords:

It can be used to measure various small molecules including the neuroregulator adenosine. Baseline levels of the compounds measured with microdialysis vary over studies. We systematically reviewe … Microdialysis Technique. Microdialysis is a minimally-invasive sampling technique that is used for continuous measurement of free, unbound analyte concentrations in extracellular fluid and was initially developed for CNS research. It can be performed in any tissue type to assess the physiological or pharmacological functions of biochemicals (e Thus, measure-ment of antimicrobial concentrations in lung tissue could lead to a critical reappraisal of current antimicrobial dosing guide-lines. To date, drug concentrations at the site of infection in the respiratory tract have been studied by assaying whole lung tissue, sputum, respiratory secretions, and pleural fluid (18–21) Microdialysis Idil Cavus Charles L. Wilson Introduction Microdialysis is a method that allows continuous in vivo sampling and neurochemical analysis of brain extracellular fluid (ECF) for extended periods of time.

Skin microdialysis (SMD) is a versatile sampling technique that can be used to recover soluble endogenous and exogenous molecules from the extracellular compartment of human skin. Due to its minimally invasive character, SMD can be applied in both clinical and preclinical settings. Despite being available since the 1990s, the technique has still not reached its full potential use as a tool to Microdialysis and 201 Tl were then used to measure K i + in the gastrocnemius medialis muscle of four humans during rest and static plantar flexion exercise. At rest, K i + was 3.9–4.3 mmol/l when the perfusate flow was 2 or 5 μl/min.

20 As more human microdialysis data are generated, intraspecies differences in drug distribution in CNS compartments as well as effects that microdialysis was first used der-matologically to measure percutane-ous penetration (Anderson et al., 1991) with probes placed in the dermis, the plain fact is that the very first publica-tions involved placement of catheters into the subcutis in order to study glu-cose metabolism (Jansson et al., 1988; Arner et al., 1988).

Microdialysis is a technique used to sample free unbound chemical substances from the extracellular medium in a specific location. 135–137 Substances may include endogenous molecules (e.g., neurotransmitters, hormones, glucose, etc.) or exogenous compounds (e.g., pharmaceutical molecules).

Microdialysis equipment and performance. The CMA Microdialysis System (Stockholm, Sweden) was used . The microdialysis pump was CMA107, a portable battery‐driven pump adjustable for different flow rates (0.1–5 μl/min).

Microdialysis is a probe-based sampling method, which, if linked to analytical devices, allows for the measurement of drug concentration profiles in selected tissues. During the last two decades, microdialysis has become increasingly popular for preclinical and clinical pharmacokinetic studies. The advantage of in vivo microdialysis over traditional methods relates to its ability to

The aim of this study was to measure, using a new microdialysis‐based approach, antibiotic penetration into the extracellular space fluid of pneumonic human lung parenchyma. Patients and methods The lung penetration of a combination of piperacillin and tazobactam, substances with low protein binding, was determined in five patients suffering from pneumonia and metapneumonic pleural empyema.

However, its potential as a tool for research in tissues other than the brain has not been fully explored. Microdialysis has been extensively used to study small molecules such as neurotransmitters, metabolites and drugs in the brain and other tissues.
