Why RL is preferred over NS in a Trauma situation?

Answer 1

For intravascular volume replenishment are typically isotonic (eg, 0.9% saline or Ringer's lactate [RL]). H2O freely travels outside the vasculature, so as little as 10% of isotonic fluid remains in the intravascular space ,RL stays in the intravascular space than NS. that is why RL preferred than NS.

Answer 2

RL (Ringer's lactate) is preferred over NS (normal saline) in a trauma situation because RL is more physiologically balanced, contains electrolytes that closely resemble those found in the body, and has a slightly more alkaline pH compared to NS. This makes RL a better choice for resuscitation in trauma as it helps to maintain acid-base balance and cellular function more effectively.
