Rationale: The FLACC (Face, Legs, Activity, Cry, Consolability) scale is commonly used to assess pain in infants and young children who are unable to verbally communicate their pain. This scale is particularly useful in assessing post-operative pain in infants as it evaluates different behaviors and physiological responses to pain. The Oucher scale is more commonly used with children who are older and can provide self-report of pain intensity. Wong-Baker FACES scale is primarily used with children who are older and can indicate their pain level by pointing to facial expressions. The 0-10 pain scale is typically used with older children and adults who can rate their pain on a numerical scale.
