Levobupivacaine, a local anesthetic agent, is indicated for the production of local or regional anesthesia or analgesia for surgery, for oral surgery procedures, for diagnostic and therapeutic procedures, and for obstetrical procedures.
Why is levobupivacaine (( S )- bupivacaine preferred clinically to Racaemic bupivacaine?
Levobupivacaine is a single-enantiomer preparation consisting of the S enantiomer of bupivacaine. Compared with racemic bupivacaine, levobupivacaine has considerably reduced CNS and cardiovascular toxicity, allowing a larger dose to be given.
Can Bupivacaine be given epidural?
Bupivacaine Hydrochloride Infusion Solution 0.125% w/v may be used: 1) for continuous infusion lumbar epidural analgesia to relieve pain during labour. 2) for continuous infusion epidural analgesia to control postoperative pain. 3) Surgical anaesthesia in adults and children above 12 years of age.
What is Marcaine used for?
Marcaine is a prescription medicine used as local anesthesia, Caudal Block, Epidural Block and nerve blocks (peripheral and sympathetic), Spinal Anesthesia and Retrotubular Anesthesia. Marcaine may be used alone or with other medications.
What is the half life of ropivacaine?
From the epidural space, ropivacaine shows complete and biphasic absorption. The half-lives of the 2 phases, (mean ± SD) are 14 ± 7 minutes and 4.2 ± 0.9 h, respectively.
What is local anaesthetic toxicity?
Local anesthetic systemic toxicity (LAST) is a life-threatening adverse event that may occur after the administration of local anesthetic drugs through a variety of routes. Increasing use of local anesthetic techniques in various healthcare settings makes contemporary understanding of LAST highly relevant.
Does Articaine contain sulfa?
Articaine is not contraindicated in patients with sulfa allergies; there is no cross-allergenicity between articaine’s sulphur-bearing thiophene ring and sulfonamides.
How long does epidural bupivacaine last?
In nerve blocks, it is injected around a nerve that supplies the area, or into the spinal canal’s epidural space. It is available mixed with a small amount of epinephrine to increase the duration of its action. It typically begins working within 15 minutes and lasts for 2 to 8 hours.
Where do you inject epidural anesthesia?
Epidural anesthesia involves the insertion of a hollow needle and a small, flexible catheter into the space between the spinal column and outer membrane of the spinal cord (epidural space) in the middle or lower back.

Kenalog, a steroid, may be injected along with the Marcaine to decrease inflammation. What is Marcaine®? Marcaine is an anesthetic. It is injected into the vaginal wall just inside the opening of the vagina.
How long does an injection of Marcaine last?
The onset of action following dental injections is usually 2 to 10 minutes and anesthesia may last two or three times longer than lidocaine and mepivacaine for dental use, in many patients up to 7 hours. The duration of anesthetic effect is prolonged by the addition of epinephrine 1:200,000.
How long does levobupivacaine last after anesthesia?
The onset of action is < or = 15 minutes with various anaesthetic techniques. In studies of surgical anaesthesia in adults, levobupivacaine provided sensory block for up to 9 hours after epidural administration of < or = 202.5 mg, 6.5 hours after intrathecal 15 mg, and 17 hours after brachial plexus block with 2 mg/kg.
How much levobupivacaine do you need for an epidural infusion?
Nurses who have completed the epidural competency may administer a bolus of 0.125% levobupivacaine +/- additive as prescribed. Two authorised persons must check and sign for the bolus on the Regional anaesthetic infusion prescription.
Which is better levobupivacaine or bupivacaine for nerve block?
The majority of in vitro, in vivo and human pharmacodynamic studies of nerve block indicate that levobupivacaine has similar potency to bupivacaine. However, levobupivacaine had a lower risk of cardiovascular and CNS toxicity than bupivacaine in animal studies.
