Which statement did Cushing make about the relationship between speed of operation and survival?

Quicker operation is associated with higher survival Longer operations increase survival The speed of operation has no effect on survival Shorter operations cause more bleeding

Correct Answer:

Quicker operation is associated with higher survival

Explanation:

Speed of operation matters for survival. Harvey Cushing observed that quicker brain operations tend to yield better outcomes because shorter exposure limits blood loss, reduces brain edema and physiological stress, and lowers the risk of complications like herniation. So a quicker operation is associated with higher survival. Longer, drawn-out surgeries increase blood loss and tissue injury, which worsen outcomes, and the speed of the operation does have an effect—faster procedures generally reduce bleeding rather than cause it.
