Which vital sign is crucial to monitor closely after thrombolytic therapy?

Monitoring blood pressure closely after thrombolytic therapy is crucial because it helps assess the risk of complications, particularly hemorrhage or bleeding, which can significantly occur following such treatment. Thrombolytic therapy works by dissolving blood clots, and while it can restore blood flow, it can also disrupt blood vessel integrity, leading to increased risk of intracranial hemorrhage or other bleeding complications if blood pressure is not appropriately controlled.

High blood pressure following thrombolysis can exacerbate this risk, as elevated pressures may stress weakened blood vessels and increase the likelihood of rupture. Therefore, maintaining optimal blood pressure within a target range is essential to minimize complications and ensure the safety of the patient during the recovery phase post-thrombolysis.
