Tag: Controlled hypotension

The practice of intentionally lowering a patient's blood pressure during surgery, known as induced hypotension, has been used clinically since the mid-20th century to minimize blood loss and provide a clearer surgical field. The specific indications for induced hypotension depend on the type of surgery, potential bleeding risk, and the patient's overall health.

Controlled hypotension can significantly reduce intraoperative blood loss and the need for blood transfusions during major spinal surgeries. This medically induced state of lower-than-normal blood pressure is a carefully managed procedure performed by an anesthesia team to improve surgical conditions and enhance patient outcomes.

For over half a century, controlled hypotension has been utilized in surgical settings to intentionally reduce a patient's blood pressure to achieve specific therapeutic purposes. This technique helps to limit blood loss, decrease the need for transfusions, and provide a clearer, less obstructed surgical field for surgeons.

Originally approved by the FDA in 1974, sodium nitroprusside is a potent and fast-acting vasodilator used intravenously in critical care settings. So, what is nitroprusside used for, and why does its use require such intensive monitoring? This article explores its primary clinical applications, mechanism of action, and associated risks.
