Bupivacaine (Marcaine) block nerve conduction and initiation by decreasing the permeability of neurons to sodium influx.
It is used in the following situations:
-
- It can be used as local or regional anesthesia;
- It is widely used in spinal anesthesia (0.75% in dextrose 8.25% injection);
- It can also be used in diagnostic and therapeutic procedures;
- It is used in obstetrical procedures (only 0.25% and 0.5% concentrations)
-
0.25%:
- Local infiltration, peripheral nerve block, sympathetic block, caudal or epidural block
-
0.5%:
- Peripheral nerve block, caudal and epidural block
-
0.75% (not for obstetrical anesthesia):
- Retrobulbar block, epidural block.
Bupivaciane Dose in Adults
- Its dose changes with the procedure, depth of anesthesia, vascularity of tissues, duration of anesthesia, and condition of the patient.
- Solutions having preservatives should not be used for caudal or epidural block.
Use in the treatment of Local anesthesia:
-
Infiltration:
- 0.25% is infiltrated locally
- The maximum dose is 175 mg.
- Aspiration is done prior to each injection; however, the absence of blood in the syringe does not guarantee that intravascular injection has been averted
-

-
Epidural block (other than caudal block; preservative-free):
- Give in 3 to 5 mL increments.
-
It gives sufficient time to detect any harmful manifestations of unintentional IV or intrathecal administration:
- 10 to 20 mL of 0.25% or 0.5% is used
-
Surgical procedures which need a high degree of muscle relaxation and prolonged effects only:
- 10 to 20 mL of 0.75% is used
-

Bupivaciane Dose in Children
- Bupivacaine dose changes with the procedure, depth of anesthesia, vascularity of tissues, duration of anesthesia, and condition of the patient.
- Formulations free of preservatives are used for administration into the CNS space (eg, epidural, caudal, spinal).
- Consider incremental administration with negative aspiration before giving the injection
- however, the absence of blood in the syringe does not guarantee that intravascular injection has been avoided.
- It should only be given under the supervision of a qualified physician experienced in the use of anesthetics.
- In pediatric patients, dosing should be based on lean body mass.

How to administer Bupivacaine?
- Preservative-containing solutions are not recommended for use in epidural and caudal blocks.
- The Infusion Pump On-Q is used to administer local anesthetics such as bupivacaine (eg lidocaine or ropivacaine) slowly to surgical wounds and/or to the peripheral nerves to provide postoperative pain relief.
- Injecting directly into the shoulder can cause articular cartilage destruction (chondrolysis).
- Never place On-Q pumps directly in any joint.
Mechanism of action of Bupivacaine (Marcaine):
- It reduces the neuronal membrane's permeability for sodium ions, which blocks both conduction and initiation of nerve impulses.
- It causes depolarization inhibition and conduction blockade.
The beginning of action: Anesthesia (route- and dose-dependent).
- Epidural: Takes up to 17 minutes to spread T6 dermatome
- Infiltration Fast
- Dental injections: 2-10 minutes
- Spinal: In 1 Minute
- Maximum dermatome level reached in 15 minutes most of the time
Duration (route and dose-dependent):
- Epidural: 2 to 7.7 hours
- Infiltration: 2 to 8 hours
- Dental injection: Up to 7 hours
- Spinal: 1.5 to 2.5 hours
Distribution: V : Infants:
- 3.9 ± 2 L/kg
- Children: 2.7 ± 0.2 L/kg
Protein binding:
- 84% to 95%
Metabolism:
- Mainly Hepatic; forms metabolite (pipecoloxylidine [PPX])
Half-life elimination (age-dependent):
- Neonates: 8.1 hours
- Adults: 2.7 hours
Time to peak, plasma:
- Caudal, epidural, or peripheral nerve block:
- 30 to 45 minutes
Excretion:
- Via Urine (~6% unchanged)
Clearance:
- Infants: 7.1 ± 3.2 mL/kg/minute
- Children: 10 ± 0.7 mL/kg/minute
Pharmacodynamics and Pharmacokinetics: Additional Considerations Geriatric:
- Elderly patients reached the maximal spread of analgesia and maximal motor blockade quickly than younger patients.
- Elderly patients also showed higher peak plasma concentrations following the administration of this product.
- The total plasma clearance was decreased in these patients.
