Itâs easy to rupture the small blood vessels in your nose, especially when itâs dry out. A deviated septum, or a shifted wall in your nose, is a common cause of both symptoms. Along with headaches and nosebleeds, a deviated septum can cause blockage in one or both nostrils, facial pain, and noisy breathing during sleep.
Tumescent anesthesia is when the surgeon injects fluid containing lidocaine (which is like the medication you get injected at the dentist) and epinephrine (which is like adrenaline) which helps constrict the blood vessels.
A UCLA Health answered. In tumescent liposuction, which is the most common kind of lipoplasty, a fluid composed of anesthetic, epinephrine, and salt water is injected into the part of your body where the operation will occur. The anesthetic (lidocaine) numbs the area while the epinephrine decreases blood loss by making blood vessels constrict.
