[Disturbances of pulmonary gas exchange after sclerotherapy for esophageal varices].

Sclerotherapy of esophageal varices is a procedure which caries high risk of DIC and ARDS syndrome induced by intravenous administration of obliterative agent. The aim of the study was to investigate hematological and arterial and venous gasometric parameters before and after injection of 5% ethanolamine oleate (EO) to the esophageal varices. These investigations were carried out in 9 patients with liver cirrhosis (Child B and C) and in 7 dogs witch were infused with EO to the inferior vena cava. Both patients and animals had the values of pAO2, pVO2, satAO2, satVO2 and platelets count decreased but pACO2 and pVCO2 increased after injection of EO. PhA and phV values increased only in investigated patients but not in dogs in which decreased values of Hb, HT and RBC after EO injection were found. This observation was not confirmed in the treated patients. Conducted investigations show that EO injections to the venous system causes significant changes in the pulmonary function in humans as well as in the dogs.

Metallic contamination of bone during drilling procedures.

The influence of drills and burs of different shapes and materials on the amount of metallic transfer was studied. In these experiments, holes were drilled in bone with radioactive tools and the amount of metal transferred to the bone was measured by means of gamma-ray spectrometry. The proportion of the drill material transferred to the bone varied widely, depending on the type of the drill, its previous usage, and on the specific element considered. Most of the drills transfer a few microgram of iron to the bone, together with smaller quantities of cobalt, tungsten, and chromium. The total quantity of material transferred to the bone from new drills exceeded that of old drills. Almost invariably, the second drilling transferred less material than did the first, even with used drills.

Investigation of variable factors in drilling bone.

Experiments were conducted to investigate the pressures that are exerted on drills during the preparation of bone. Twenty operators used six different types of drills at high and low speeds to prepare standardized holes and slots in animal bone. The peak vertical forces exerted varied between 5.98 and 24.32 newtons (x = 12.45 newtons). The mean vertical forces varied between 4.22 and 18.93 newtons (x = 9.16 newtons). Spear point and twist drills were associated with significantly lower operating pressures and shorter operating times than round and fissure burs. These differences, however, were much less than the interoperator variations.
