[Morphologic and functional changes in thrombocytes after deep freezing with DMSO].
During the past decade much work has been carried out towards establishing the optimum method for cryopreservation of platelets. Among the various cryoprotectants dimethyl sulfoxide (DMSO) has been shown to be the most effective. This report describes ultrastructural and functional changes of platelets during the deep-freezing process with DMSO. ⋯ Although cryopreserved platelets are characterized by hemostatic effects in vivo, it seems conceivable that these effects could be improved by further development of platelet-freezing techniques.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of two solutions with different glucose concentrations for infusion therapy during laparotomies in infants.
Comparison of two commercially available solutions for intraoperative infusion therapy during laparotomies in infants using a standardized anesthetic technique (combination of general anesthesia with a caudal block). ⋯ Solutions containing 5.5% glucose infused with 8 ml/kg/h caused in both age groups of infants intolerable hyperglycemias. In young infants, also a solution containing 2.5% glucose infused at a rate of 8 ml/kg/h leads to hyperglycemia, while in older children this amount of glucose is tolerated. It is recommended that for abdominal surgery in young infants glucose and fluid substitution is separated, in order to infuse glucose at an even lower rate. Still, blood glucose levels have to be monitored closely.

Case Reports[Use of plasmapheresis in a 62-year-old patient with severe infection].
The elimination of cytotoxic substances from blood as part of sepsis treatment has been controversely discussed so far. The following case report demonstrates the advantages and disadvantages of this therapy strategy. ⋯ The temporary improvement during plasmapheresis suggests that the patient might have profited from plasmapheresis-related optimized oxygen delivery, controlled diuresis and decrease of oxygen consumption. In addition we hypothesized that elimination of high-molecular cytokines and toxines contributed to the improvement under plasmapheresis. Using plasmapheresis one has to consider the high costs, risk of infection, and the unexplained mode of action to the mediatory process. Therefore we cannot recommend this treatment in general. Further controlled studies should investigate the therapeutic benefits of plasmapheresis in patients with severe sepsis.
