Cerebral injury is seen in one of three patients with multiple traumas; thus efficient shock treatment is a most important measure against the development of secondary brain damage. Small-volume resuscitation in severe hemorrhagic shock by hypertonic/hyperoncotic saline/dextran has been shown to instantaneously normalize cardiac output and to raise systemic(More)
Small-volume resuscitation with 7.2% NaCl/10% dextran 60 (HHS) restores cardiovascular stability faster than all other therapeutic modalities currently known. This study was undertaken to elucidate the effects of HHS on the brain, specifically on the formation of posttraumatic brain edema. HHS was administered to anesthetized albino rabbits with or without(More)
BACKGROUND Basal insulin is frequently administered once daily. This subgroup analysis of a multicenter, randomized, parallel study compared insulin glargine (Lantus Aventis Pharmaceuticals, Bridgewater, NJ) with neutral protamine Hagedorn (NPH) insulin in patients with type 2 diabetes, evaluating only patients treated previously with once-daily NPH(More)
Severe head injury is frequently associated with extracranial injuries causing hemorrhagic hypotension. Volume replacement with isotonic fluids not only is therapeutically of limited efficacy but may aggravate posttraumatic brain edema. On the other side, hypertonic/hyperoncotic saline/dextran solution (HHS) shown to restore cardiovascular function in(More)
The efficacy of the diuretic agent torasemide, which antagonizes the Na+/K+/Cl- cotransport and Cl- channels, was investigated to determine its inhibition of brain edema from a focal cerebral lesion. For this purpose, cold injury of the brain was induced in 50 Sprague-Dawley rats while monitoring arterial blood pressure. The brain was removed for(More)
These studies were conducted to determine the effect of anesthetic drugs on tissue perfusion and O2 supply in the brain with focal cerebral edema. Using an open cranium preparation, we studied the effects of isoflurane (I; 1 minimum alveolar anesthetic concentration), of fentanyl (F; 0.5-1 microgram.kg-1 x min-1), or of thiopental (T; 32.5 mg.kg-1 x h-1) on(More)
Using the dorsal skin fold chamber model in the hamster, we analyzed local tissue partial oxygen pressure (PO2) in the striated skin muscle under nonischemic and postischemic conditions with a Clark-type multiwire oxygen surface electrode. Hypervolemic infusion (500 mg x kg(-1) I.V.) or isovolemic exchange transfusion (3.3 gm x kg(-1) I.V.; hematocrit 30%)(More)
Hypertonic/hyperoncotic solutions (e.g. HHS: 7.2% NaCl/10% dextran-60) are highly effective to normalize cardiovascular function in hemorrhagic shock due to rapid mobilization of fluid from the extravascular compartment. Since experiences are limited with regard to potential side effects of this treatment on the central nervous system, the present studies(More)
Brain oedema is an important factor which compromises maintenance of the cerebral blood flow. Conversely, primary blood flow disturbances are leading to brain oedema. The mechanisms underlying blood flow impairment by brain oedema are associated with an increased regional tissue pressure in proportion to the degree of water accumulation in the parenchyma.(More)
