Paresthesia, a short-to-long-term numbness or altered sensation affecting a nerve, is a well-known complication of injectable local anesthetics and has been present even before articaine was available. [17] An article by Haas and Lennon published in 1993 [18] seems to be the original source for the controversy surrounding articaine. This paper ...
Superficial vein thrombosis (SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis , which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness .
A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor.
During treatment if the patients feel faint or experiences a drop in blood pressure, lay them flat and keep their legs elevated in an attempt to restore their blood pressure.

Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot.It results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.
Chitosan bonds with platelets and red blood cells to form a gel-like clot which seals a bleeding vessel. Unlike other hemostat technologies its action does not require the normal hemostatic pathway and therefore continues to function even when anticoagulants like heparin are present. [9]
The area postrema is a circumventricular organ and as such lies outside the blood–brain barrier; it can therefore be stimulated by blood-borne drugs that can stimulate vomiting or inhibit it. [5] There are various sources of input to the vomiting center:
