How does hypernatremia develop in burn patients during the acute phase, and what are its manifestations?

Hypernatremia in burn patients during the acute phase can develop due to excessive fluid replacement with hypertonic solutions or tube-feeding therapy. Its manifestations include thirst, dry and coated tongue, lethargy, confusion, and possibly seizures.

In the acute phase of burn management, hypernatremia may arise after successful fluid resuscitation if large amounts of hypertonic solutions are used. Additionally, inappropriate fluid administration or tube-feeding therapy can contribute to this condition. The clinical signs of hypernatremia include increased thirst, a dry and coated tongue, lethargy, confusion, and in severe cases, seizures, indicating a need for careful monitoring of serum electrolyte levels during treatment.
