Appendix 5. Volumes of RL and ORS for rehydration

Contenido

    These tables are designed to:

    • Simplify the prescription of standard rehydration protocols on admission, according to the degree of dehydration and age or weight if weight is known;
    • Facilitate implementation and monitoring of the protocol, by describing standard treatment procedures for severe dehydration or hypovolaemic shock (IV route, Plan C) and some dehydration (oral route, Plan B). 

     

    5.1 Severe dehydration in children 5 years and over and adults (RL, Plan C)
    5.2 Severe dehydration in children under 5 years (RL, Plan C)
    5.3 Severe dehydration in children under 5 years with severe malnutrition (RL, Plan C)
    5.4 Some dehydration in children and adults (ORS, Plan B)

     

    This appendix gives an overview of what the patient should receive, how, and over what length of time it should be delivered for correctly administered, effective rehydration.
    These tables should not be seen as an extremely rigid framework, they are to be used as a guide, following as closely as possible the protocol as administered in ideal conditions. 

     

    The quantities of RL and ORS are rounded off (to the nearest lower or higher whole number) to facilitate practical administration, as the quantity of liquids lost is always an estimation (approximately 10% for severe dehydration and 7.5% for some dehydration). 

     

    RL is administered through:

    • A standard infusion set (1 ml = 20 drops) in children 5 years and over and adults;
    • A "precision" paediatric infusion set (1 ml = 60 drops; 150 ml chamber; dead volume: approximately 15 ml) in children under 5 years. 

     

    The flow rates are given in ml/minute or ml/hour as they are too high to be given in drops/minute.
    During rapid fluid replacement time (“bolus”), the infusion set clamp should be opened without trying to count the number of drops. The bolus is administered in the presence of a nurse or doctor that closely monitors the patient and the volume being delivered. The infusion rate is then lowered to administer the rest of the RL, monitoring the volume delivered and to be delivered over 3 hours (4 hours maximum), except for specific cases requiring slower rehydration (such as severe malnutrition).
    Once rehydration has been completed, the catheter is not removed. Further treatment depends on the patient’s clinical evolution and capacity to drink ORS.
