--------------------------------------------------------------------------------------------------------------------

This information is intended solely for healthcare professionals.

Mepivacaína Normon 20 mg/ml should only be used by experienced anesthesiologists or under their supervision. Equipment for resuscitation should be available when administering local anesthetics. The lowest effective dose should be administered. The dose should be adjusted individually according to the specific case.

Dosage

Always use the smallest dose required to produce the desired anesthesia. Dosage should be adjusted individually according to the patient's age and weight as well as the specific case.

Regional anesthesia and peripheral nerve blocks

The dose should not exceed 400 mg.

The maximum daily dose is 1g.

Mepivacaína Normon 20 mg/ml injectable solution can be administered continuously.

For different types of use, the following doses are recommended:

For more details on the doses to be applied for anesthetizing specific nerves or for specific anesthetic techniques, consult standard textbooks.

Geriatric patients

Lower doses may be necessary for elderly patients or those in poor general health.

Pediatric population

The doses for adolescents from 15 years old are the same as those for adults.

Not indicated for patients under 15 years old.

Hepatic insufficiency

No dose reduction is necessary for surgical anesthesia in patients with hepatic insufficiency.

When using prolonged blocks, for example, through repeated administration, the repeated doses of mepivacaína should be reduced by 50% in patients with Child-Pugh grade C liver disease and the total dose in 24 hours should not exceed 750 mg of mepivacaína.

Renal insufficiency

No dose reduction is necessary for surgical anesthesia until 24 hours in patients with renal dysfunction.

Administration

• Perineural, epidural for nerve conduction blockade.
• 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 intravascularly located.The injection should be performed slowly and in fractions.

Basic guidelines to follow:

1. Choose the smallest possible dose.
2. Use a needle of the appropriate size.
3. Inject slowly with multiple aspirations in two planes (rotate the needle 180°). Be very careful to avoid accidental intravascular injection. It is essential to perform careful aspiration.
4. Monitor blood pressure.
5. Consider 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.
6. If necessary, suspend the administration of anticoagulants before administering the local anesthetic.
7. Observe general and specific contraindications for various local or regional anesthesia methods.

For continuous epidural administration, mepivacaína solutions should be more diluted.

For epidural anesthesia, a test dose should be administered, consisting of 3 - 4 ml of a local anesthetic with added adrenaline (1: 200,000) before the full dose, as intravascular injection of adrenaline is quickly recognized due to the increase in heart rate. Heart rate should be measured repeatedly until 5 minutes after administration of the test dose.

Verbal contact with the patient should be maintained and heart rate should be measured repeatedly until 5 minutes after 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 signs of toxicity.

Before administering a local anesthetic, ensure that the necessary equipment for resuscitation, e.g. oxygen source, material for maintaining a free airway, and emergency medication for treating toxic reactions, is available immediately.
