1. What Lidocaine solution for injection is and what it is used for
Lidocaine Hydrochloride is a local anesthetic and belongs to a class of drugs called amide type local anesthetics. It produces loss of feeling or sensation confined to one part of the body. Lidocaine Hydrochloride Injection may be used to produce local numbness (anesthesia) by injection of the solution into or around the area of operation. It may also be used to produce local anesthesia by injection of the solution close to the nerves whose conduction is to be cut off, or into the epidural space near the spinal cord, or by administering the solution into a vein in a limb that has been isolated from the circulation by means of a tourniquet (bandage that stops the flow of blood from vessel by applying pressure).
2. What you need to know before you use Lidocaine solution for injection

• if you are allergic to other similar amide type anaesthetics.
• if you suffer from state of decreased blood volume (hypovolaemia).
• if you suffer from abnormality of impulse propagation in the heart causing decreased blood pressure, slow heart rate (complete heart block)
