Thank you for asking!
The term reactionary hemorrhage is usually reserved for post operative wounds where first 48 hours bleeding is called that.When you have closed an operation wound it may start bleeding: (1) During the first 48 hours (reactionary haemorrhage) because a clot in a vessel has been displaced, or a ligature has slipped. Or, (2) 8 to 14 days later (secondary haemorrhage) when the wound has become infected and eroded a vessel, usually quite a small one, sometimes a larger one. One of the purposes of monitoring a patient immediately after an operation is to watch for reactionary haemorrhage, so make sure your staff observe him carefully, and take his pulse and blood pressure regularly.

Now hypertension normalization abruptly disturbs starling mechanisms of the hemodynamics inside the vessels modifying their compliances and stretch laplace laws, leading to stasis of blood which leads to clots and reactionary hemorrhages with exhaustion coagulopathies.
I hope you understood every word i said.
