Xylocaine (lidocaine HCl) Injections are sterile, nonpyrogenic, aqueous solutions that contain a local anesthetic agent with or without epinephrine and are administered parenterally by injection.Click to see full answer. Similarly, it is asked, what dental anesthesia does not have epinephrine?Alternatives to epinephrine-containing anesthesia include Prilocaine and Carbocaine, or even nitrous oxide (“laughing gas”). Plain old Lidocaine is also a decent choice.Additionally, what do dentists use instead of lidocaine? Local anesthetic agents in dentistry In dentistry, the most commonly used local anesthetic is lidocaine (also called xylocaine or lignocaine), a modern replacement for procaine (also known as novocaine). Its half-life in the body is about 1.5–2 hours. Similarly one may ask, what is the difference between lidocaine and lidocaine with epinephrine? There is NO BENEFIT to adding Lidocaine to Bupivacaine for speed of onset of anesthesia. The use of local anesthetic agents WITHOUT Epinephrine produces a significantly SHORTER duration of action. Lidocaine with Epinephrine should provide adequate anesthesia for AT LEAST 3 HOURS.Why is epinephrine added to lidocaine for local anesthesia? Dosage and administration The addition of epinephrine 5 micrograms/ml (1:200 000) as a vasoconstrictor to local anaesthetic solutions slows systemic absorption and prolongs the anaesthetic effect. In dental surgery, in which small volumes are injected, concentrations of 12.5 micrograms/ml (1:80 000) are commonly used.
