Objective: To compare the mean hemoglobin levels and frequency of polycythemia in full term neonates after early delayed cord clamping. Study Design: Randomized Controlled Trial. Setting: KRL General Hospital Islamabad (Labor Room/ Neonatology). Periods: December 2017 to June 2018. Material & Methods: 190 were selected divided into 2 equal groups randomly: Early clamping group delivery late...

AIM To study effects of a perfluorocarbon emulsion on plasma and whole human blood viscosity in the presence of albumin or modified fluid gelatin. MATERIAL AND METHODS We investigated the effects of several PFC concentrations on plasma and whole blood viscosity in the presence of human albumin solution (HAS) or modified fluid gelatine (MFG; Gelofusine) to obtain three PFC emulsion concentrati...

A practical approach to reduce the interferences of biochemicals and hematocrit ratio (Hct%) in the determination of whole blood glucose using multiple screen-printed carbon electrode (SPCE) test strips is described. SPCE test strips with and without glucose oxidase [i.e., GOD(+)-SPCEs and GOD(-)-SPCEs] were used and the chronoamperometric currents of test glucose solutions with various spiked ...

We have compared the effects of an increase in perfusate viscosity induced by dextran and by hematocrit (Hct) on segmental vascular resistance in the pulmonary circulation and the effect of flow on microvascular resistance in lungs perfused with dextran and red blood cells. We isolated and perfused lungs of 39 neonatal rabbits weighing 670 +/- 250 g. To determine the effect of dextran, group 1 ...

The effect of small hematocrit (Hct) increases on cardiac index (cardiac output / body weight) and oxygen release to the microcirculation was investigated in the awake hamster window chamber model, by means of exchange transfusions of homologous packed red blood cells. Increasing Hct between 8-13% from baseline increased cardiac index by 5 31% from baseline (P < 0.05) and significantly lowered ...

The effect of small hematocrit (Hct) increases on cardiac index (cardiac output/body wt) and oxygen release to the microcirculation was investigated in the awake hamster window chamber model by means of exchange transfusions of homologous packed red blood cells. Increasing Hct between 8 and 13% from baseline increased cardiac index by 5-31% from baseline (P < 0.05) and significantly lowered sys...

BACKGROUND Blood transfusion is used to treat acute anemia with the goal of increasing blood oxygen-carrying capacity as determined by hematocrit (Hct) and oxygen delivery (DO2). However, increasing Hct also increases blood viscosity, which may thus lower DO2 if the arterial circulation is a rigid hydraulic system as the resistance to blood flow will increase. The net effect of transfusion on D...

Previous studies have shown that differing qualities of blood specimen seem to influence whole blood electrical aggregometry (WBEA), making it difficult to standardize the method. The aim of this study was to investigate the impact of hematocrit (HCT) and platelet count (PLC) on in vitro platelet aggregation in citrated whole blood (CWB) in order to compensate for their possible effects on impe...

Background: Drug abuse and drug dependence are very common in the community, which causes complications patients. It is necessary to identify these complications. Objectives: The aim of this study was compare blood parameters oral inhaled opium addicts with healthy individuals Zahedan. Methods: This performed on 60 people (20 group addicts, 20 group). After recording demographic information, we...

BACKGROUND The aim of this study was to evaluate the course of hemoglobin (HGB) concentration and hematocrit (HCT) in donor blood during and after preparatory plasmaphereses (PP) without NaCl and with an infusion of 500 ml 0.9% NaCl during PP. METHODS After informed consent 32 plasma donors were studied in a crossover design. They underwent PP once without NaCl infusion and once, on a differe...
