Comparative Study
Comparative study of the thermal properties of mud and peat solutions applied in clinical practice.
Different peloids as e.g. mud and peat have been traditionally used for therapeutic purposes successfully, especially of there thermal actions. It was the aim of the experimental study to compare the thermal properties of two peloids, mud and peat, with a view to assessing their thermal effects when they are applied in clinical practice. ⋯ The comparative studies of the thermal properties of water and water solutions of peat and curative mud show that the thermal effect of the water bath is substantially smaller than that of the peat and mud applications. This difference is due to a greater extent to the high values of the dynamic viscosity, not allowing cooling by convection and protecting the surface of the skin upon applications of peloid solutions with a higher temperature.

Whole-body cooling can be used in the treatment of various brain pathologies, for example, after hypoxic events. Potential complications include haemodynamic instability, coagulation disorders and infection. Selective brain cooling (SBC) would therefore appear to make good sense. ⋯ Under SBC the cortical temperature dropped from 38.4 degrees C to 27.7 degrees C while the core temperature remained stable. In an animal model SBC was successfully accomplished via the pharynx. Further studies should now be done to evaluate the effectiveness of this approach in larger animals with potentially different anatomical features.
