Fifth-degree burn injuries also may require amputation due to damage to muscles. If amputation is not needed, skin grafting will be required.

In sixth-degree burns, the surrounding skin will appear white or black, and everything up to the bone is burnt. This means all layers of skin, muscle ligaments, tendons, and the bone are damaged. Due to the destruction of the nerves, the victim may not feel pain but will go into shock.

Why RL is used in burns?
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.
