Hartmann's (or Lactated Ringer's) solution is the preferred first-line fluid recommended by the British Burns Association. Its composition and osmolality closely resemble normal bodily physiological fluids and it also contains lactate which may buffer metabolic acidosis in the early post- burn phase.

What is the purpose of administering intravenous fluid for the treatment of a burn?

Through clinical experience, we know that adequate volumes of IV fluids are required to prevent burns shock in those with extensive burn injuries. The aim of resuscitation is to restore and maintain adequate oxygen delivery to all tissues of the body following the loss of sodium, water and proteins.

Which IV fluid is best for burns?

Begin fluid resuscitation with Normal Saline or Hartmann's Solution for burns >20%TBSA in adults, and for burns >10%TBSA in children <16 years old. Where appropriate, warm IV fluid administration should be considered to help minimise heat loss.
