Are you using manual hexadimethrine bromide (polybrene) test in blood cross matching? Watch out! Abstract: BACKGROUND: Blood cross matching test mainly includes manual hexadimethrine bromide (polybrene) test (MPT) and the automatic analyzer method (by coombs card) at the Department of blood transfusion. Generally instrumental method is used for large quantities of samples. It can save manpower; MPT is used for emergency and few samples. it can save time. Our department recently encountered a case

The Sanskirt Proverb states‚ “for breath is life‚ and if you breathe well you will live long on earth” This could not be more true. Without oxygen‚ life itself would be nonexistent. Imagine what would happen if wounds did not get better‚ incisions did not heal‚ and burns did not improve. This is where hyperbaric oxygen therapy (HBOT) comes into play. Oxygen is necessary for the replenishment of tissues‚ healing of the body and assisting with general ailments. HBOT is used for a wide variety of treatments

1) Explain why alveolar gas has a different composition from air. Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary

HYPOXIA Introduction Hypoxia is simply a lack of oxygen at the tissue level of the body due to a decreased partial pressure of oxygen in the inspired air. Hypoxia is serious‚ because it may lead to death. Diseases of the blood‚ the heart and circulation‚ and the lungs may all produce some form of hypoxia. There are four types of hypoxia: (1) the hypoxic type‚ in which the oxygen pressure in the blood going to the tissues is too low to saturate the haemoglobin; (2) the anaemic type‚ in which

Jaundice in Newborns Jaundice is caused by an increase in blood levels of bilirubin‚ which is a waste product made when haemoglobin in red blood cells is broken down. Newborn babies have immature liver enzymes and are unable to chemically transform (metabolise) this bilirubin effectively for later excretion. Babies who are born underweight and those born to diabetic mothers are particularly likely to become jaundiced. Physiological Jaundice A natural build-up of unmetabolised bilirubin is

A varicose vein is a superficial vein with a faulty valve. The calf muscles squeezes the deep veins in the leg and pressure is reduced in the superficial veins. These superficial veins are fitted with special one-way valves to prevent the blood running backwards. The weight of blood in the vein is conciderable especially while standing still and the blood flow is against gravity. and blood is allowed to pool stretching the walls of the veins which damage the valves resulting in the lumen being unable
