How do you dilute bupivacaine?
Discard diluted solutions in 30 days. →Bupivacaine: Dilute the 0.5% (5 mg/ml) Bupivacaine 1:2 to get final concentration of 0.25% (2.5 mg/ml) (for example: take 1 cc of Bupivacaine and add 1 cc of Sterile, pyrogen-free water to an amber, sterile, multi-use vial).
How do you buffer bupivacaine?
Buffered bupivacaine was prepared by adding 0.3 mL of 8.4% sodium bicarbonate to a 30-mL vial of 0.5% bupivacaine. In preliminary experiments, this volume of sodium bicarbonate increased the pH of bupivacaine from 5.4 to 7.15; further titration resulted in visible precipitation.
What percent is bupivacaine?
Bupivacaine 0.25%w/v and 0.5%w/v solution for injection are used for the production of local anaesthesia by percutaneous infiltration, peripheral nerve block(s) and central neural block (caudal or epidural), that is, for specialist use in situations where prolonged anaesthesia is required.

What does 0.5% bupivacaine mean?
Bupivacaine Hydrochloride is indicated for the production of local or regional anesthesia or analgesia for surgery, dental and oral surgery procedures, diagnostic and therapeutic procedures, and for obstetrical procedures. Only the 0.25% and 0.5% concentrations are indicated for obstetrical anesthesia.
How much epinephrine do I add to bupivacaine?

Is bupivacaine HCl autoclaved?
BUPIVACAINE HCl is available in a sterile isotonic solution with epinephrine (as bitartrate) 1:200,000. Solutions of BUPIVACAINE HCl containing epinephrine may not be autoclaved. BUPIVACAINE HCl is related chemically and pharmacologically to the aminoacyl local anesthetics. It is a homologue of mepivacaine and is chemically related to lidocaine.
How much isobaric and hyperbaric bupivacaine is used in spinal anesthesia?
The effects of spinal anesthesia with 0.5% isobaric and hyperbaric (8% glucose) bupivacaine were investigated in 45 patients who had lower limb or lower abdominal surgery. The patients were divided into 3 groups. Group 1 patients received 3 ml of 0.5% isobaric bupivacaine.
What is the local anaesthetic effect of bupivacaine?
Onset and duration of the local anaesthetic effect of bupivacaine depends on the dose and site of administration. Bupivacaine, like other local anaesthetics, causes a reversible blockade of impulse propagation along nerve fibres by preventing the inward movement of sodium ions through the cell membrane of the nerve fibres.
