Herein we will discuss the potential uses of this substance in plastic surgery and then provide background information on chemical composition, FDA history, toxicity, relationship to tissue and flap perfusion, and other medical applications. DMSO is metabolized in humans by oxidation into dimethyl sulfone (MSM), or by reduction into dimethyl sulfide (DMS), both of which are excreted in urine and feces.

We do not know how the actions of these available MSM products compare with DMSO, but these products deserve further investigation if they do eliminate the garlic odor. Dimethyl Sulfoxide (DMSO), one of the strongest organic solvents, has been used commercially for several decades. Chemical Compatibility yes of course, there are somekind of solvents that dissolved oil METHOCEL is a trademark of the Dow Chemical Company. Variations in temperature, concentrations, durations of exposure and other factors may affect the performance of the product. 5. DMSO was administered to volunteers from a prison population in California who were involved in either a short-term (14 day) or long-term (90 day) study organized by Brobyn.40 A battery of tests were conducted before, during, and after the study start and stop points, including complete weekly physicals, ophthalmologic examinations, bone marrow studies, cerebrospinal fluid analysis, neurological exams (including electroencephalograms), pulmonary function studies, and electrocardiograph exams, as well as regular urine and blood analysis (including the full range of blood chemistries).

It seems reasonable to try DMSO when other more traditional methods of improving circulation, such as releasing tension, relieving kinks from pedicles, or decreasing pressure, have failed. In this model, 10 2.5-cm flaps were elevated and then resutured on the backs of rabbits.6 Four groups were compared: (1) those treated with saline; (2) those treated with 8% hydrogen peroxide (H2O2); (3) those treated with 50% DMSO; and (4) those treated with 50% DMSO + 8% H2O2. Intravenous DMSO was very effective in reversing acute ischemic renal failure in rats.57 DMSO increased myocardial perfusion in dogs58 and rats59 and has effectively improved liver perfusion after microvascular injury in rats, probably by reducing leukocyte adhesion to the sinusoidal wall.60, Because DMSO is an organic solvent with multiple applications in industry and medicine, it is readily available throughout the United States. WebZinc sulfate, 10%. They recommend application of topical DMSO every 4 to 6 hours, until blood flow improves, to areas that show signs of ischemia or less than adequate perfusion.

Masterflex Tubing Compatibility Database | VWR Good experimental and anecdotal evidence indicates that DMSO increases tissue perfusion and may effectively treat or prevent ischemia in flaps. DMSO got a reputation for toxicity in 1965 that has not been overcome, even though studies have determined that lens changes do not occur in humans or other primates treated with DMSO. Injections of DMSO into the spinal cord soon after injury have shown great promise for restoring function.

Suggested DMSO Formulations for Industrial Solvent Replacement Antioxidants, such as vitamin C, are important components of good skin care. A strong, vibrant research and development group is the lifeblood of all industries. The analgesic property of DMSO combined with its ability to rapidly deliver drugs into tissues may be applicable to topical lidocaine. It can be purchased in some health food stores and through hundreds (if not thousands) of Web sites at a concentration of 70% or 90% for less than $10.00 for an 8-ounce bottle. Investigators have been studying this application of DMSO in cerebral ischemia since the 1970s.5154 To examine DMSO in a clinical setting, 20 patients in Turkey with severe closed head injuries were given intravenous DMSO.55,56 In both studies (10 patients per study) DMSO rapidly reduced intracranial pressure, increased cerebral perfusion pressure and blood flow, and improved outcomes so that most patients had no residual deficits. %PDF-1.5 Since that discovery, more than 12,300 English-language articles about the medical implications of DMSO and its clinical mechanisms of action have been cataloged by the National Library of Medicine. This Onyx system is currently used in Europe for intracranial aneurysms that cannot be treated with surgery or have not responded to other occlusion attempts.39 In this context, the FDA may be willing to approve the use of DMSO in a potentially life-saving device that requires minimal patient exposure. Transcutaneous oxygen tension (PtcO2) in the flaps was measured 72 hours after surgery, and the percentage of surviving skin area was measured by planimetry 7 days after flap elevation.
