deliberate hypotension

deliberate hypotension

a technique in general anesthesia in which a short-acting hypotensive agent is administered to reduce blood pressure and thus bleeding during surgery. The procedure facilitates surgery by making vessels and tissues more visible and reducing blood loss. Also called hypotensive anesthesia, hypotensive technique.
