Mechanism of Action
Stabilizes neuronal membranes by inhibiting the ionic fluxes required for the initiation and conduction of impulses, thereby effecting local anesthetic action.Epinephrine
Stimulates both alpha- and beta-receptors within sympathetic nervous system; relaxes smooth muscle of bronchi and iris and is an antagonist of histamine.
Indications and Usage
Production of local or regional anesthesia by infiltration techniques such as percutaneous injection, by peripheral nerve block techniques such as brachial plexus and intercostals, and by central neural techniques such as lumbar and caudal epidural blocks.
History of hypersensitivity to local anesthetics of the amide type.
Dosage and Administration
Dose determined by number of dermatomes to be anesthetized (2 to 3 mL/dermatome). The dose of local anesthetic administered varies with the procedure, vascularity of the tissues, depth of anesthesia, degree of required muscle relaxation, duration of anesthesia desired, and the physical condition of the patient. Reduce dosages for children, the elderly, debilitated patients, and patients with cardiac or liver disease. Consult individual prescribing information for dosage recommendations.
- For local infiltration only. Not for intravascular administration.
- Multiple concentrations are available. Ensure that the proper concentration is being used.
- Do not administer if particulate matter, cloudiness, or discoloration noted.
- To avoid intravascular administration, aspirate injection site before anesthetic solution is injected.
- Do not use anesthetic solutions containing preservatives for epidural or spinal anesthesia.
- Discard any unused solution when using single dose vial or ampule.
Store at 59° to 86°F.
Drug InteractionsErgot derivatives (ergotamine), vasopressors
May cause severe persistent hypertension or cerebrovascular accidents.MAOIs (eg, isocarboxazid), tricyclic antidepressants (eg, amitriptyline)
Severe prolonged hypertension may occur.Phenothiazines (eg, thioridazine), butyrophenones (droperidol)
May reduce or reverse the pressor effect of epinephrine.
Laboratory Test Interactions
Lidocaine IM injection may increase creatine phosphokinase levels, which may compromise the diagnosis of acute MI.
Bradycardia; hypotension (3%); cardiovascular collapse; cardiac arrest.
Excitation; depression; lightheadedness; nervousness; apprehension; euphoria; confusion; dizziness; drowsiness; sensations of heat, cold, or numbness; twitching; tremors, convulsions, unconsciousness; positional headache (3%); shivering (2%).
Tinnitus; blurred or double vision; permanent injury to extraocular muscles.
Vomiting; loss of bowel control.
Loss of bladder control; loss of sexual function.
Respiratory depression or arrest.
Allergy (eg, cutaneous lesions, urticaria, edema, anaphylactoid reactions); backache.
Category B .
Reduce dose; commensurate with age, body weight, and physical condition.
Special Risk Patients
Use with caution in areas of the body supplied by end arteries or having compromised blood supply, patients with neurological disease, spinal deformities, septicemia and severe hypertension, impaired CV function, or hepatic disease.
Peripheral or hypertensive vascular disease
May exhibit exaggerated vasoconstrictor response and ischemic injury or necrosis may result.
- Explain name, dose, action, and potential adverse reactions of drug.
- Advise patient that medication will be prepared and administered by a health care provider in a medical setting.
- Caution patient that temporary loss of sensation and motor activity may be experienced.
- Instruct patient to inform health care provider if any of the following are experienced during or after the anesthetic injection: restlessness; anxiety; ringing in the ears; dizziness; blurred vision; drowsiness or change in mental status; rapid heart rate, rapid breathing or feeling of shortness of breath; hot or cold sensations.
