Administration

The following dosage recommendations should be regarded as a guide for use in the average adult:

Spinal anesthesia for surgery: 2-4 ml (10-20 mg Bupivacaine hydrochloride) The patient's physical status and concomitant medication should be considered when deciding the dose, and the lowest dose required for adequate anesthesia should be used. Duration varies with dose, while segmental spread may be difficult to predict, especially with the isobaric (plain) solution. The dose should be reduced in the elderly and in patients in the late stages of pregnancy.

Pediatrics: Bupivacaine may be used in children. One of the differences between small children and adults is a relatively high CSF volume in infants and neonates, requiring a relatively larger dose/kg to produce the same level of block as compared to adults.

<5 kg: 0.40-0.50 mg/kg
5 to 15 kg: 0.30-0.40 mg/kg
15 to 40 kg: 0.25-0.30 mg/kg

Effects

The adverse reaction profile for Bupivacaine is similar to those for other long acting local anesthetics administered intrathecally. Adverse reactions caused by the drug per se are difficult to distinguish from the physiological effects of the nerve block (e.g. decrease in blood pressure, bradycardia, temporary urinary retention), events caused directly (e.g. nerve trauma) or indirectly (e.g. epidural abscess) by the needle puncture or events associated to cerebrospinal leakage.

Indications

Pharmacology

Bupivacaine is a long acting local anesthetic of the amide type. Bupivacaine spinal 5 mg/ml is a sterile non-glucose containing solution. Bupivacaine spinal has a rapid onset of action. The duration of analgesia is 3-5 hours in the lower thoracic and lumbar segments, which makes Bupivacaine spinal especially suitable for long lasting procedures in the lower limbs. The muscular relaxation of the lower limbs is profound, and lasts 3-4 hours, being somewhat shorter than the duration of the sensory blockade. The circulatory effects of Bupivacaine spinal are similar or less than those seen with other spinal agents. Bupivacaine spinal is well tolerated by all tissues with which it comes in contact.

Precautions

Local anesthetics react with certain metals and cause the release of their respective ions which, if injected, may cause severe local irritation. The ampoules are designed for single use only; any unused portions of solutions should be discarded. The solution should be used immediately after opening the ampoule. Solutions showing discoloration should not be used.
