Use of plasma volume substitutes and plasma in developing countries.

Plasma and plasma substitutes are used in the treatment of various conditions such as haemorrhage and shock. This article examines the role of crystalloids, artificial colloids, human plasma, human albumin, and plasma protein fraction, in the treatment of such patients, with particular reference to peripheral health facilities in developing countries.It is concluded that 0.9% saline, together with 5-6% dextrose, is of particular importance in this situation since it is easy to produce locally, is stable at high temperatures, and has a low cost/benefit ratio. The second priority is to ensure the availability of a limited quantity of one or more colloid plasma substitutes. In the field of plasma, fresh frozen or fresh liquid plasma is most useful for the treatment of various haemostatic derangements and follow-up treatment of severe burns, since it contains the widest spectrum of therapeutically useful components and can be produced locally with an acceptable degree of difficulty.The treatment of severe diarrhoea with special alkaline electrolyte solutions and oral rehydration solutions is also outlined.
