Permissive hypotension
Permissive Hypotension
Permissive hypotension (pronunciation: per-miss-ive hy-po-ten-shun) is a medical strategy used in the management of certain trauma patients to allow for a lower than normal blood pressure.
Etymology
The term "permissive hypotension" is derived from the English words "permissive," meaning allowing or characterized by great or excessive freedom of behavior, and "hypotension," which is a condition of abnormally low blood pressure.
Definition
Permissive hypotension is a concept in trauma resuscitation where a lower than normal blood pressure is allowed to persist with the aim of reducing the risk of hemorrhage or bleeding. This is based on the understanding that aggressive fluid resuscitation, which is used to normalize blood pressure, can dislodge blood clots and increase bleeding.
