The effect of the physical factors of treatment on lipid peroxidation in surgical infections in patients with diabetes mellitus

Lipid peroxidation was studied in 179 patients with purulent surgical diseases and diabetes mellitus. Magnetotherapy, laser radiation, low-frequency ultrasound, ultraviolet irradiation of blood, and sorbent application were used as therapeutic factors. It was found that laser and ultraviolet irradiation of blood, and application of sorbents to the purulent wounds promoted stabilization of lipid peroxidation, had a more marked effect on the course of the wound process, and reduced the term of treatment.     

Analysis of a linear peristaltic infusion device for the transfusion of red cells to pediatric patients

A linear peristaltic infusion device was evaluated for red cell (RBC) transfusion in the pediatric and neonatal setting. CPDA-1 RBC units (n = 24) divided into six groups of 4 units each underwent simulated transfusion. Blood was infused by using manufacturer-provided administration sets with either a 21-gauge needle or a 24-gauge catheter. Filters were used in two groups to evaluate the effect of negative pressure on filter function. Two groups of RBCs less than 1 week old were washed, irradiated, and infused at 5 mL per hour, by using a standard administration set, or at 10 mL per hour, by using a syringe set. Four-week-old RBCs (washed and irradiated, irradiated and filtered, filtered only, or unmanipulated) were infused at 100 mL per hour. Paired samples from 0 and 2 hours before and after infusion were analyzed for hemoglobin, hematocrit, RBC count, plasma hemoglobin, lactate dehydrogenase, potassium, alanine aminotransferase, and aspartate aminotransferase. Hausser and Nageotte hemocytometers were used to perform white cell (WBC) counts when a filter was used. By analysis of variance and percentage of change, data from 0 and 2 hours before and after infusion were compared. No clinically or statistically significant differences were seen for hemoglobin, hematocrit, or RBC count. The difference in preinfusion and postinfusion plasma hemoglobin levels in washed RBCs at 2 hours was statistically but not clinically significant (14.5 +/− 6.8 vs. 19.3 +/− 7.1 mg/dL). No clinically significant differences were noted for the remaining analytes.(ABSTRACT TRUNCATED AT 250 WORDS)
