A mixture of 1 part 2% lidocaine with 3 parts 0.5% bupivacaine provides 0.5% lidocaine and 0.375% bupivacaine. This has the advantages of immediate anesthesia with lidocaine during injection to minimize injection pain while providing a longer duration of action with a lowered concentration of bupivacaine.

Bupivacaine, marketed under the brand name Marcaine among others, is a medication used to decrease sensation in a specific small area. [5] In nerve blocks, it is injected around a nerve that supplies the area, or into the spinal canal's epidural space. [5] It is available mixed with a small amount of epinephrine to increase the duration of its ...
Lidocaine is an antiarrhythmic medication of the class Ib type. [7] This means it works by blocking sodium channels thus decreasing the rate of contractions of the heart. [10] [7] When injected near nerves, the nerves cannot conduct signals to or from the brain. [8] Lidocaine was discovered in 1946 and went on sale in 1948. [11]
Occasionally a 'pop' is felt as the needle tip passes through the muscle cone delineating the retrobulbar space. Following a negative aspiration for blood, 2–4 mLs of local anesthetic solution is injected and the needle is withdrawn. 2% Lidocaine (Xylocaine) and 0.5% to 0.75% bupivicaine (Marcaine) are two commonly used agents. Epinephrine ...
Compared to lidocaine cream, delay sprays with lidocaine tend to be faster-acting and easier to apply. This can make a spray a great option if you need a topical treatment that can be applied ...
Local anesthetic injections are given in specific areas of the mouth, rather than the whole body. Although several different medications are available, the most commonly used local anesthetic to prevent pain in the area around a tooth is lidocaine (also called xylocaine or lignocaine). Lidocaine's half-life in the body is about 1.5–2 hours. [2]
Since then, several synthetic local anesthetic drugs have been developed and put into clinical use, notably lidocaine in 1943, bupivacaine in 1957, and prilocaine in 1959. The invention of clinical use of local anaesthesia is credited to the Vienna School which included Sigmund Freud (1856-1939), Carl Koller (1857-1944) and Leopold Konigstein ...
It has a significantly shorter duration of action than lidocaine and is significantly less toxic. Chloroprocaine has a motor block lasting for 40 minutes, a rapid onset time of 3–5 minutes (9.6 min ± 7.3 min at 40 mg dose; 7.9 min ± 6.0 min at 50 mg dose) and a time to ambulation of 90 minutes without complications, especially lacking ...
