The 0.75% solution of bupivacaine hydrochloride is no longer recommended for obstetric anesthesia, since use of this concentration for epidural anesthesia in obstetric patients has been associated with cardiac arrest with difficult resuscitation or death. Cardiac arrest has occurred after seizures resulting from systemic toxicity, apparently following inadvertent intravascular injection.
American Society of Health System Pharmacists; AHFS Drug Information 2009. Bethesda, MD. (2009), p. 3335
Local anesthetics should only be employed by clinicians who are well versed in diagnosis and management of dose-related toxicity and other acute emergencies which might arise from the block to be employed, and then only after insuring the immediate availability of oxygen, other resuscitative drugs, cardiopulmonary resuscitative equipment, and the personnel resources needed for proper management of toxic reactions and related emergencies. delay in proper management of dose-related toxicity, under ventilation from any cause, and/or altered sensitivity may lead to the development of acidosis, cardiac arrest and, possibly, death. /Local anesthetics/

Some commercially available formulations of bupivacaine hydrochloride contain sodium metabisulfite, a sulfite that may cause allergic-type reactions, including anaphylaxis and life-threatening or less severe asthmatic episodes, in certain susceptible individuals. The overall prevalence of sulfite sensitivity in the general population is unknown but probably low; such sensitivity appears to occur more frequently in asthmatic than in nonasthmatic individuals.

Bupivacaine 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. Bupivacaine is indicated to induce post-surgical analgesia in adults for up to 72 hours following arthroscopic subacromial decompression by administration into the subacromial space under direct arthroscopic visualization. Bupivacaine, together with the NSAID [meloxicam], is indicated for the production of postsurgical analgesia in adult patients for up to 72 hours following bunionectomy, open inguinal herniorrhaphy or total knee arthroplasty.
FDA Label
Exparel is indicated as a brachial plexus block or femoral nerve block for treatment of post-operative pain in adults, and as a field block for treatment of somatic post-operative pain from small- to medium-sized surgical wounds in adults.
Postsurgical analgesia
Bupivacaine is a widely used local anesthetic agent. Bupivacaine is often administered by spinal injection prior to total hip arthroplasty. It is also commonly injected into surgical wound sites to reduce pain for up to 20 hours after surgery. In comparison to other local anesthetics it has a long duration of action. It is also the most toxic to the heart when administered in large doses. This problem has led to the use of other long-acting local anaesthetics:ropivacaine and levobupivacaine. Levobupivacaine is a derivative, specifically an enantiomer, of bupivacaine. Systemic absorption of local anesthetics produces effects on the cardiovascular and central nervous systems. At blood concentrations achieved with therapeutic doses, changes in cardiac conduction, excitability, refractoriness, contractility, and peripheral vascular resistance are minimal. However, toxic blood concentrations depress cardiac conduction and excitability, which may lead to atrioventricular block, ventricular arrhythmias and to cardiac arrest, sometimes resulting in fatalities. In addition, myocardial contractility is depressed and peripheral vasodilation occurs, leading to decreased cardiac output and arterial blood pressure. Following systemic absorption, local anesthetics can produce central nervous system stimulation, depression or both.
Anesthetics, Local
Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate. (See all compounds classified as Anesthetics, Local.)

Absorption
Systemic absorption of local anesthetics is dose- and concentration-dependendent on the total drug administered. Other factors that affect the rate of systemic absorption include the route of administration, blood flow at the administration site, and the presence or absence of epinephrine in the anesthetic solution. Bupivacaine formulated for instillation with [meloxicam] produced varied systemic measures following a single dose of varying strength. In patients undergoing bunionectomy, 60 mg of bupivacaine produced a Cmax of 54 33 ng/mL, a median Tmax of 3 h, and an AUC of 1718 1211 ng\*h/mL. For a 300 mg dose used in herniorrhaphy, the corresponding values were 271 147 ng/mL, 18 h, and 15,524 8921 ng\*h/mL. Lastly, a 400 mg dose used in total knee arthroplasty produced values of 695 411 ng/mL, 21 h, and 38,173 29,400 ng\*h/mL.
Route of Elimination
Only 6% of bupivacaine is excreted unchanged in the urine.
After absorption into the blood, bupivacaine hydrochloride is more highly bound to plasma proteins than are any other local anesthetics; bupivacaine is reportedly 82-96% bound. Bupivacaine hydrochloride has the lowest degree of placental transmission of parenteral local anesthetics and may cause the least fetal depression.

Pregnant rats received an intravenous infusion of bupivacaine at a rate of 0.33 mg. kg-1. min-1 over a period of 15 min. The fetuses were delivered either at the end of infusion or at 2 or 4 hr after dosing. Maternal and fetal blood and tissue samples were obtained for the assays of bupivacaine and its metabolites using capillary gas chromatography-mass spectrometry. The elimination half-life of bupivacaine was 37.7 min. The major metabolite was 3'-hydroxybupivacaine. Bupivacaine and 3'-hydroxybupivacaine were present in all samples at the end of administration. The fetal to maternal concentration ratio of bupivacaine in plasma was 0.29, and in the placenta was 0.63. The amnion contained the highest bupivacaine concentration: threefold higher in the maternal and 11-fold higher than in the fetal plasma. At 4 hr after dosing, bupivacaine was no longer detectable in any maternal and fetal samples, whereas 3'-hydroxybupivacaine was still present in all tissues except the fetal plasma and heart. These data indicate that a considerable amount of bupivacaine is taken up by both sides of the placenta, as well as the amnion and myometrium. 3'-Hydroxybupivacaine was present in all tissues except the fetal plasma and heart samples, even after the parent compound became no longer detectable.

Pharmacokinetic studies on the plasma profile of Bupivacaine Hydrochloride after direct intravenous injection suggest a three-compartment open model. The first compartment is represented by the rapid intravascular distribution of the drug. The second compartment represents the equilibration of the drug throughout the highly perfused organs such as the brain, myocardium, lungs, kidneys, and liver. The third compartment represents an equilibration of the drug with poorly perfused tissues, such as muscle and fat. The elimination of drug from tissue distribution depends largely upon the ability of binding sites in the circulation to carry it to the liver where it is metabolized.

Local anesthetics such as bupivacaine block the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential. Bupivacaine prevents depolarization by bindng to the intracellular portion of sodium channels and blocking sodium ion influx into neurons. In general, the progression of anesthesia is related to the diameter, myelination and conduction velocity of affected nerve fibers. Clinically, the order of loss of nerve function is as follows: (1) pain, (2) temperature, (3) touch, (4) proprioception, and (5) skeletal muscle tone. The analgesic effects of Bupivicaine are thought to potentially be due to its binding to the prostaglandin E2 receptors, subtype EP1 (PGE2EP1), which inhibits the production of prostaglandins, thereby reducing fever, inflammation, and hyperalgesia.
