<p>The IV dose of Ringer&#39;s lactate solution is usually calculated by estimated fluid loss and presumed fluid deficit. For fluid resuscitation the usual rate of administration is 20 to 30 ml/kg body weight/hour. RL is not suitable for maintenance therapy (i.e., maintenance fluids) because the sodium content (130 mEq/L) is considered too low, particularly for children, and the potassium content (4 mEq/L) is too low, in view of electrolyte daily requirement. Moreover, since the lactate is converted into bicarbonate, longterm use will cause patients to become&nbsp;alkalotic. Ringer&#39;s lactate and other crystalloids are also used as vehicles for the IV delivery of drugs.<br />

In a large-volume resuscitation over several hours, LRS maintains a more stable blood pH than normal saline.</p>
