OBJECTIVE To investigate haematological variations and iron related changes in the serum of participants in a 1600 kilometre ultramarathon run. PARTICIPANTS Seven male and two female participants in a 1600 km foot race. METHODS Blood samples were obtained from the participants before, after four and 11 days of running, and at the end of the event. Samples were analysed by standard methods f...

A univentricle with parallel pulmonary and systemic circulations is inherently inefficient because mixing of pulmonary and systemic venous return occurs. Thus a cavopulmonary anastomosis is used as a staged palliative procedure to reduce volume overload in patients with cyanotic congenital heart disease. On the basis of oxygen uptake and consumption, an equation was derived that related cardiac...

Sickle cell disease is characterized by microvascular occlusion and hemolytic anemia, factors that impair tissue oxygen delivery. We use visible reflectance hyperspectral imaging to quantitate skin tissue hemoglobin oxygen saturation (HbO2) and to determine whether changes in blood flow during nitric oxide (NO) stimulation or gas administration (therapies proposed for this disease) improve skin...

1. Serum prealbumin, transferrin and iron concentrations were measured in ninety-two north Cameroonian children under 5 years of age. The results were grouped according to the blood haemoglobin concentration range in order to show the interactions of anaemia with prealbumin and transferrin concentrations. 2. Transferrin concentration showed a significant negative correlation with serum Fe and p...

Ventilation and arterial oxygen saturation have been measured in 18 patients during anaesthesia with ether or halothane carried in air. All patients were ventilated artificially with a Jefferson ventilator at a frequency of 16 breaths per minute and variable tidal volume. Ventilation has been expressed as a percentage of Radford's standard, Nunn's standard and the patient's pre-operative restin...

Iron deficiency anemia(IDA) is one of the most common nutritional problems in the world.children under 5 years old are considerd as the high risk group consisting a high proportion of IDA patients.in this group,due to the specific conditions,the complication of anemia may lead to serious consequences.this study was designed to determine the prevalence of IDA in 1-5 years old children.A total of...

Introduction: Several pathological conditions can reduce blood supply to the organs, among which burns can be mentioned. By developing the volume depletion and reducing the cardiac contractility, burns can cause hypoperfusion. Further, in ICUs, since the finger pulse oximetryis commonly used instead of the measurement of the nasal alar oxygen saturation, the use of finger probe restricts pulse ...

background : mechanical ventilation is used for some infants in neonatal intensive care units (nicu) due to many physiological and clinical causes. since these patients have endotracheal tubes, cleaning and keeping the airways open through suctioning should be done to increase oxygenation. this study aimed to evaluate effect of open and closed suctioning methods on respiratory parameters of inf...
