The greater the burn area, the more serious the exudate, the more obvious the thirst. Because the burn patient exudate is not only water, but also contains electrolytes, plasma and other components. In principle, oral rehydration solution should be drunk in small amounts and increased or decreased as appropriate, never arbitrarily meet the patient’s thirst requirements. For patients with severe burns, in addition to oral rehydration (pulsation), the main route of rehydration is through intravenous replenishment of blood volume to relieve thirst.
