Use |
|
Local anesthetic (injectable) for peripheral nerve block, infiltration,
sympathetic block, caudal or epidural block, retrobulbar
block |

Contraindications |
|
Hypersensitivity to bupivacaine hydrochloride or any component,
para-aminobenzoic acid or parabens |
|
|
Warnings/Precautions |
|
Use with caution in patients with liver disease. Some commercially available
formulations contain sodium metabisulfite, which may cause allergic-type
reactions. Pending further data, should not be used in children <12 years of
age and the solution for spinal anesthesia should not be used in children <18
years of age. Do not use solutions containing preservatives for caudal or
epidural block; convulsions due to systemic toxicity leading to cardiac
arrest have been reported, presumably following unintentional intravascular
injection. 0.75% is not recommended for obstetrical
anesthesia. |
|
|
Adverse
Reactions |
|
1% to 10% (dose related):
Central nervous system: Seizures, restlessness, anxiety, dizziness
Gastrointestinal: Nausea, vomiting
Neuromuscular & skeletal: Weakness
Ocular: Blurred vision
Otic: Tinnitus
Respiratory: Apnea |
|
|
Overdosage/Toxicology |
|
Treatment is primarily symptomatic and supportive. Termination of anesthesia
by pneumatic tourniquet inflation should be attempted when the agent is
administered by infiltration or regional injection
Bradyarrhythmias (when the heart rate is <60) can be treated with I.V., or
S.C. atropine 15 mcg/kg
With the development of metabolic acidosis, I.V. sodium bicarbonate 0.5-2
mEq/kg and ventilatory assistance should be instituted
Methemoglobinemia should be treated with methylene blue 1-2 mg/kg in a 1%
sterile aqueous solution I.V. push over 4-6 minutes repeated up to a total dose
of 7 mg/kg. |

|
Drug
Interactions |
|
Increased effect: Hyaluronidase
Increased toxicity: Beta-blockers, ergot-type oxytocics, MAO inhibitors,
TCAs, phenothiazines, vasopressors |
|
|
Stability |
|
Solutions with epinephrine should be protected from
light |
|
|
Mechanism of
Action |
|
Blocks both the initiation and conduction of nerve impulses by decreasing the
neuronal membrane's permeability to sodium ions, which results in inhibition of
depolarization with resultant blockade of conduction |
|
|
Pharmacodynamics/Kinetics |
|
Onset of anesthesia (dependent on route administered): Within 4-10 minutes
generally
Duration of action: 1.5-8.5 hours
Metabolism: In the liver
Half-life (age dependent): Neonates: 8.1 hours; Adults: 1.5-5.5 hours
Elimination: Small amounts (~6%) excreted in urine |
|
|
Usual Dosage |
|
Dose varies with procedure, depth of anesthesia, vascularity of tissues,
duration of anesthesia and condition of patient. Metabisulfites (in
epinephrine-containing injection); do not use solutions containing preservatives
for caudal or epidural block.
Children: 1-3.7 mg/kg
Adults: 15-30 mL of 0.25% or 0.5%
Epidural block (other than caudal block):
Children: 1.25 mg/kg/dose
Adults: 10-20 mL of 0.25% or 0.5%
Peripheral nerve block: 5 mL dose of 0.25% or 0.5% (12.5-25 mg); maximum: 2.5
mg/kg (plain); 3 mg/kg (with epinephrine); up to a maximum of 400 mg/day
Sympathetic nerve block: 20-50 mL of 0.25% (no epinephrine) solution
|
|
|
Administration |
|
Solutions containing preservatives should not be used for epidural or caudal
blocks |

Patient
Information |
|
This medication is given to reduce sensation in the injected area. You will
experience decreased sensation to pain, heat, or cold in the area and/or
decreased muscle strength (depending on area of application) until the effects
wear off; use necessary caution to reduce incidence of possible injury until
full sensation returns. If used in mouth, do not eat or drink until full
sensation returns. Immediately report chest pain or palpitations; increased
restlessness, anxiety, or dizziness; skeletal or muscle weakness; difficulty
breathing; ringing in ears; or changes in vision. Pregnancy/breast-feeding
precautions: Inform prescriber if you are pregnant. Do not
breast-feed. |
