There have been reports of cardiac arrest with difficult resuscitation or death during use of bupivacaine for epidural anesthesia in obstetrical patients. In most cases, this has followed use of the 0.75% (7.5 mg/mL) concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management. Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% (7.5 mg/mL) concentration of bupivacaine is not recommended for obstetrical anesthesia and should be reserved for surgical procedures where a high degree of muscle relaxation and prolonged effect are necessary.
Note: Dose varies with procedure, depth of anesthesia, vascularity of tissues, duration of anesthesia, and condition of patient; commercially available epinephrine concentrations may not be appropriate in pediatric patients. Preservative-free formulations are recommended for administration into the CNS space (eg, epidural, caudal, spinal). Consider incremental administration with negative aspiration prior to each injection; however, absence of blood in the syringe does not guarantee that intravascular injection has been avoided (Ref). Should only be administered under the supervision of a qualified physician experienced in the use of anesthetics. In obese pediatric patients, the preferred weight used for dose calculation is undefined and specific pediatric data are sparse (Ref); some have suggested the use of lean body mass/weight not ideal body weight (IBW) (Ref). Refer to Bupivacaine monograph for specific bupivacaine with or without epinephrine dosing details.
There are no dosage adjustments provided in manufacturer's labeling; use with caution.

(For additional information see "Bupivacaine and epinephrine: Drug information")
Dose varies with procedure, depth of anesthesia, vascularity of tissues, duration of anesthesia, and condition of patient. Do not use solutions containing preservatives for caudal or epidural block. Doses may be repeated up to once every 3 hours (maximum: 400 mg/day of bupivacaine).
Caudal and lumbar epidural block test dose (preservative free): 2 to 3 mL of 0.5% (maximum: 15 mg/dose of bupivacaine or 15 mcg/dose of epinephrine)
Caudal block (preservative free): 15 to 30 mL of 0.25% or 0.5% (maximum: 75 mg/dose of 0.25% bupivacaine or 150 mg/dose of 0.5% bupivacaine)
Epidural block (other than caudal block, preservative free): 10 to 20 mL of 0.25% or 0.5% (maximum: 50 mg/dose of 0.25% bupivacaine or 100 mg/dose of 0.5% bupivacaine). Administer in 3 to 5 mL increments, allowing sufficient time to detect toxic manifestations of inadvertent IV or intrathecal administration.
Surgical procedures requiring a high degree of muscle relaxation and prolonged effects only: 10 to 20 mL of 0.75%; Note: Not to be used in obstetrical cases (maximum: 150 mg/dose of bupivacaine)
Local anesthesia: Infiltration: 0.25% infiltrated locally (maximum: 400 mg/day of bupivacaine)
Peripheral nerve block: 5 mL of 0.25% or 0.5% (maximum: 400 mg/day of bupivacaine)
Retrobulbar anesthesia: 2 to 4 mL of 0.75% (maximum: 30 mg/dose of bupivacaine)
Sympathetic nerve block: 20 to 50 mL of 0.25% (maximum: 125 mg/dose of bupivacaine)
Dental block: 1.8 mL (9 mg) of bupivacaine as a 0.5% solution with epinephrine 1:200,000 per injection site. A second dose may be administered if necessary to produce adequate anesthesia after allowing up to 10 minutes for onset. Up to a maximum of 90 mg of bupivacaine per dental appointment. The effective anesthetic dose varies with procedure, intensity of anesthesia needed, duration of anesthesia required, and physical condition of the patient; always use the lowest effective dose along with careful aspiration.
The following numbers of dental carpules (1.8 mL) provide the indicated amounts of bupivacaine 0.5% and vasoconstrictor (epinephrine 1:200,000). See table.

See individual agents.
Hypersensitivity to bupivacaine, epinephrine, amide-type local anesthetics, or any component of the formulation; obstetrical paracervical block anesthesia; IV regional anesthesia (Bier block).
Concerns related to adverse effects:
• Cardiovascular effects: Bupivacaine-containing products have been associated with rare occurrences of arrhythmias, cardiac arrest, and death.
• Intra-articular infusion-related chondrolysis: Continuous intra-articular infusion of local anesthetics after arthroscopic or other surgical procedures is not an approved use; chondrolysis (primarily shoulder joint) has occurred following infusion, with some requiring arthroplasty or shoulder replacement.
• Methemoglobinemia: Has been reported with local anesthetics; clinically significant methemoglobinemia requires immediate treatment along with discontinuation of the anesthetic and other oxidizing agents. Onset may be immediate or delayed (hours) after anesthetic exposure. Patients with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, exposure to oxidizing agents or their metabolites, or infants <6 months of age are more susceptible and should be closely monitored for signs and symptoms of methemoglobinemia (eg, cyanosis, headache, rapid pulse, shortness of breath, lightheadedness, fatigue).
• Respiratory arrest: Local anesthetics have been associated with rare occurrences of sudden respiratory arrest, especially when administered near the head or neck.
• Seizures: Convulsions due to systemic toxicity leading to cardiac arrest have also been reported, presumably following unintentional intravascular injection or administration near the head or neck.
Disease-related concerns:
• Cardiovascular disease: Use with caution in patients with cardiovascular disease (including heart block and hypotension) or compromised blood supply.
• Hepatic impairment: Use with caution in patients with hepatic impairment.
Special populations:
• Acutely ill patients: Use with caution in acutely ill patients; dose reduction may be required.
• Debilitated patients: Use with caution in debilitated patients; dose reduction may be required.
• Older adult: Use with caution in the elderly; dose reduction may be required.
• Pediatric: Not recommended for use in children <12 years of age.
Dosage form specific issues:
• Obstetrical anesthesia: [US Boxed Warning]: The bupivacaine 0.75% (7.5 mg/mL) concentration is not recommended for obstetrical anesthesia. There have been reports of cardiac arrest with difficult resuscitation or death during use of bupivacaine for epidural anesthesia in obstetrical patients. In most cases, this has followed use of the 0.75% (7.5 mg/mL) concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management. Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% (7.5 mg/mL) concentration should be reserved for surgical procedures where a high degree of muscle relaxation and prolonged effect are necessary.
• Preservative-containing solutions: Do not use solutions containing preservatives for caudal or epidural block.
• Sodium metabisulfite: Some commercially available formulations contain sodium metabisulfite, which may cause allergic-type reactions.
Other warnings/precautions:
• Administration: Use the lowest effective dose and fractional (incremental) doses when possible; repeat administration may result in accumulation of bupivacaine and metabolites. Intravascular and intrathecal injections should be avoided; aspiration should be performed prior to administration; the needle must be repositioned until no return of blood can be elicited by aspiration; however, absence of blood in the syringe does not guarantee that intravascular or intrathecal injection has been avoided.
• Test dose: A test dose is recommended prior to epidural administration (prior to initial dose) and all reinforcing doses with continuous catheter technique.
• Trained personnel: Dental practitioners and/or clinicians using local anesthetic agents should be well trained in diagnosis and management of emergencies that may arise from the use of these agents. Resuscitative equipment, oxygen, and other resuscitative drugs should be available for immediate use.

Spironolactone: May decrease vasoconstricting effects of Alpha-/Beta-Agonists. Risk C: Monitor
Sympathomimetics: May increase adverse/toxic effects of Sympathomimetics. Risk C: Monitor
Technetium Tc 99m Tilmanocept: Coadministration of Local Anesthetics and Technetium Tc 99m Tilmanocept may alter diagnostic results. Management: Avoid mixing and simultaneously co-injecting technetium Tc 99m tilmanocept with local anesthetics. This interaction does not appear to apply to other uses of these agents in combination. Risk C: Monitor
Tedizolid: May increase adverse/toxic effects of Sympathomimetics. Specifically, the risk for increased blood pressure and heart rate may be increased. Risk C: Monitor
Tricyclic Antidepressants: May increase vasopressor effects of Alpha-/Beta-Agonists. Management: Avoid, if possible, the use of alpha-/beta-agonists in patients receiving tricyclic antidepressants. If combined, monitor for evidence of increased pressor effects and consider reductions in initial dosages of the alpha-/beta-agonist. Risk D: Consider Therapy Modification
Valproic Acid and Derivatives: May increase adverse/toxic effects of BUPivacaine. Specifically, the risk of methemoglobinemia may be increased. Risk C: Monitor
Vasopressin: Alpha-/Beta-Agonists (Direct-Acting) may increase hypertensive effects of Vasopressin. The effect of other hemodynamic parameters may also be enhanced. Risk C: Monitor
[US Boxed Warning]: The bupivacaine 0.75% (7.5 mg/mL) concentration is not recommended for obstetrical anesthesia. There have been reports of cardiac arrest with difficult resuscitation or death during use of bupivacaine for epidural anesthesia in obstetrical patients. In most cases, this has followed use of the 0.75% (7.5 mg/mL) concentration. Resuscitation has been difficult or impossible despite apparently adequate preparation and appropriate management. Cardiac arrest has occurred after convulsions resulting from systemic toxicity, presumably following unintentional intravascular injection. The 0.75% (7.5 mg/mL) concentration should be reserved for surgical procedures where a high degree of muscle relaxation and prolonged effect are necessary.
Use in obstetrical paracervical block anesthesia is contraindicated (may cause fetal bradycardia and death).
Refer to individual monographs for additional information.
Local anesthetics bind selectively to the intracellular surface of sodium channels to block influx of sodium into the axon. As a result, depolarization necessary for action potential propagation and subsequent nerve function is prevented. The block at the sodium channel is reversible. When drug diffuses away from the axon, sodium channel function is restored and nerve propagation returns.
Epinephrine prolongs the duration of the anesthetic actions of bupivacaine by causing vasoconstriction (alpha-adrenergic receptor agonist) of the vasculature surrounding the nerve axons. This prevents the diffusion of bupivacaine away from the nerves resulting in a longer retention in the axon
Refer to Bupivacaine; epinephrine reduces the rate of absorption and peak plasma concentration of bupivacaine
