1. Avaliação da responsividade cardiovascular por meio da variação de pulso com diferentes fluídos em modelo experimental de hemodiluição normovolêmica aguda / Assessment of cardiovascular responsiveness through variation in pulse with different fluids in an experimental model of acute normovolemic hemodilution
Background: Pulse pressure variation (PPV), have been shown to be useful tools to indicate fluid responsiveness in clinical and experimental studies. However, this parameter has not been adequately explored in situations of acute variation of blood viscosity, as happens in acute normovolemic hemodilution (ANH). The purpose of this research was to compare the

2. Alterações plasmáticas do cobre e do zinco em crianças submetidas a cirurgia cardíaca com circulação extracorpórea
The cardiac surgery, comprising extracorporeal circulation, is known to trigger oxidative stress due to the formation of reactive oxygen species and free radicals during the periods of ischemia and reperfusion. They are hazardous to the heart cell components and regarded as responsible for the myocardial stunned. These processes are intricately associated wi

3. A randomised prospective study on treatment of central retinal vein occlusion by isovolaemic haemodilution and photocoagulation.
Thirty eight patients with ischaemic and non-ischaemic central retinal vein occlusion were evaluated for the effect of isovolaemic haemodilution. They were allocated at random to a haemodilution group (19 patients, panretinal photocoagulation and isovolaemic haemodilution) and a control group (19 patients, panretinal photocoagulation). Haematocrit was lowere

4. Effects of polycythaemia and haemodilution on circulation in neonates.
Haemodilution in nine neonates resulted in significant mean (SEM) decrease of packed cell volume (0.67 (0.01) to 0.55 (0.01)) and increases in cardiac output (250 (16) to 308 (25) ml/min/kg) and blood flow velocities of the internal carotid artery and the coeliac artery (+20%). However, red cell flows in the aorta, carotid and coeliac arteries did not change

5. The effect of isovolaemic haemodilution and intravenous glycerol on the sequelae of middle cerebral artery occlusion in the rat.
The therapeutic potential of isovolaemic haemodilution and osmotherapy on the sequelae of middle cerebral artery occlusion has been studied in an animal model. The territory of the middle cerebral artery that failed to fill with a carbon black intravascular marker after intracranial occlusion for 30 minutes in the anaesthetised rat was reduced by 50% by isov

6. Haemodilution as a cause of anaemia in coalworkers
Chan, B. W. B. (1969).Brit. J. industr. Med.,26, 237-239. Haemodilution as a cause of anaemia in coalworkers. Blood volume measurements were made in eight cases of anaemia in coal-workers, including four men with Caplan's syndrome (rheumatoid pneumoconiosis), and in eight non-anaemic patients with chronic lung disease without significant arterial hypoxia. Th

7. A randomised prospective study of treatment of non-ischaemic central retinal vein occlusion by isovolaemic haemodilution.
In a randomised study 25 patients over 50 years of age with non-ischaemic central retinal vein occlusion (CRVO) were assigned to either a treatment (14 patients, isovolaemic haemodilution) or a control group (11 patients, no treatment). After three months eight eyes in patients with haemodilution improved, whereas none of the untreated eyes had better visual

8. Haemorheological changes in patients with retinal vein occlusion after isovolaemic haemodilution.
In 83 patients with central retinal vein occlusion and branch vein occlusion we measured the haematocrit (HCT), plasma viscosity (PV), red cell aggregation (RCA), red cell filterability (RCF) and apparent whole blood viscosity (WBV). A control group (n = 41) was matched for sex, age, and cardiovascular risk factors. Measurements were performed before and aft
