This information is intended only for healthcare professionals.
Mepivacaine Normon 20 mg/ml should only be used by doctors with experience in regional anesthesia and resuscitation techniques or under their supervision. Resuscitation equipment should be available when local anesthetics are administered. The lowest possible dose that produces the desired effect should be administered. The dose should be adjusted individually according to the specific characteristics of each case.
Dosage
The smallest dose required to produce the desired anesthesia should always be used. The dosage must be adjusted individually according to the patient's age and weight, as well as the specific characteristics of each case.
Caudal and epidural anesthesia, peripheral nerve blocks
The dose should not exceed 400 mg.
The maximum daily dose is 1g.
Mepivacaine Normon 20 mg/ml injectable solution can be administered continuously.
For different types of uses, the following doses are recommended:
Sciatic nerve block | 15 - 20 ml |
Brachial plexus block | 3 - 5 ml |
Ophthalmic surgery | |
| 3 ml |
| 5 - 7.5 ml |
Epidural anesthesia for surgery | 5 - 15 ml |
Caudal anesthesia | 10 - 20 ml |
For more details on the doses to be applied for anesthetizing specific nerves or for specific anesthetic techniques, consult standard textbooks.
Elderly patients
Lower doses may be necessary for elderly patients or those in poor general health.
Pediatric population
The doses for adolescents from 15 years of age are the same as those indicated for adults.
It is not indicated for children under 15 years of age.
Hepatic impairment
In patients with hepatic impairment, dose reduction is not necessary for surgical anesthesia.
When prolonged blocks are used, for example, through repeated administration, repeated doses of mepivacaine should be reduced by 50% in patients with liver disease of grade C (Child-Pugh classification), and the total dose in 24 hours should not exceed 750 mg of mepivacaine.
Renal impairment
Dose reduction is not necessary for surgical anesthesia in patients with renal dysfunction up to 24 hours.
Administration
- Perineural, epidural route for nerve conduction block.
- Ophthalmic surgery: administration routes for peri- and retrobulbar blocks.
Local anesthesia should not be injected into infected areas.
Before injection, ensure that the needle is not placed intravascularly.The injection should be performed slowly and fractionally.
Basic rules to follow:
- Choose the smallest possible dose.
- Use a needle of the appropriate size.
- Inject slowly with several aspirations in two planes (rotate the needle 180°). Great care should be taken to avoid accidental intravascular injection. Careful aspiration is essential.
- Monitor blood pressure.
- Take into account premedication. Premedication should include the prophylactic administration of atropine and, depending on the convenient amounts of local anesthetic to be injected, a short-acting barbiturate.
- If necessary, suspend the administration of anticoagulants before the administration of the local anesthetic.
- Observe the general and specific contraindications for the various methods of local or regional anesthesia.
For continuous epidural administration, more diluted mepivacaine solutions should be used.
For epidural anesthesia, a test dose should be administered, which consists of 3-4 ml of a local anesthetic with added adrenaline (1:200,000) before the full dose, as an intravascular injection of adrenaline is quickly recognized due to the increase in heart rate. The heart rate should be measured repeatedly until 5 minutes after the administration of the test dose.
Verbal contact with the patient should be maintained, and the heart rate should be measured repeatedly until 5 minutes after the administration of the test dose. Aspiration should be repeated before administering the main dose. The main dose should be injected slowly, and especially when increasing the dose, constant contact with the patient should be maintained. Administration should be interrupted immediately at the first symptoms of toxicity.
Before administering a local anesthetic, ensure that the necessary equipment for resuscitation, such as an oxygen source, material to keep the airway clear, and emergency medication for the treatment of toxic reactions, is available immediately.
