Novocain is an anesthetic that was widely used in the USSR for local anesthesia, both when removing teeth, opening purulent abscesses, and for performing any operations under local anesthesia.
Novocain: Key Features
Novocain - instructions for use of this drug contains the following key characteristics, which do not allow to apply this local anesthetic in large quantities, due to its shortcomings and the emergence of much more modern anesthesia drugs.
Disadvantages of novocaine -
- weak analgesic effect
- no analgesic effect in inflamed tissues,
- short duration of anesthesia
- high allergy and toxicity to the body
- Do not use Novocaine during pregnancy or feeding categorically!
Novocain: price and release form
Novocaine ampoules may contain either a 0.5% solution or a 2% solution. The cost of 1 package of novocaine (10 vials of 5 ml) will be approximately 30-50 rubles.
In the 90s, the anesthetic Lidocaine came to replace Novocain, which is now widely used in medicine and dentistry in particular. Lidocaine is 2 times stronger than Novocain for the depth of anesthesia and the duration of the effect, and it also works well in inflamed tissues. Much less allergic and toxicity of the drug.
Modern analogues of novocaine in dentistry -
Despite the continued widespread use of lidocaine in medical practice, in dentistry, it has long since been withdrawn from this anesthetic. The most effective at the moment are articaine-based anesthetics. Such anesthetics include: Ultracain, Ubuteszin, Septanest and others.
These drugs for local anesthesia are no longer available in ampoules, like novocaine or lidocaine, but in special cartridges (Fig. 2). Kapula anesthetic is ready for use, it does not need to open; it is inserted into a special carpool syringe (Fig. 1), and the needle is screwed further into the syringe with the carpool (Fig. 3).

The use of novocaine for electrophoresis, compresses and dilution of antibiotics -
Electrophoresis with novocaine is not very effective. It is best to use Lidocaine 2% for electrophoresis anesthetic (sold in 2 ml ampoules).
Compress with Dimexidum and Novocain -
Compresses with dimexide are very often prescribed by maxillofacial surgeons, especially for traumatic facial injuries (fractures of the facial bones, without open wounds). Compresses have a very good effect and, for example, can reduce swelling and inflammation of the soft tissues in case of a fracture of the jaw after several procedures.
Dimexide Novocain compress: proportions
A compress with Dimexidum and Novocain is used only externally. When applying the compress on the face you need to use 20-25% concentration of Dimexidum. To do this, dilute the dimexide in proportion: to 1 part of dimexide - three parts of warm boiled water. When applied to less sensitive areas of the body, more concentrated solutions can be used (30, 35, 40%).
To moisten gauze napkins with the solution diluted with water. Apply the contents of 1 ampoule of novocaine (5 ml of solution) directly onto wetted wipes. Attach the napkins to the desired area. A plastic wrap should be applied on top of the napkin, completely blocking the area of the applied gauze napkin with the solution. Apply a layer of fabric over polyethylene (the thicker the fabric, the stronger the thermal effect will be - keep this in mind!) And bandage it.
The time of one compress is 20-30 minutes. The course of treatment is 10-12 procedures (1 procedure per day). By experience, it can be said that to enhance the analgesic effect, it is better to use lidocaine rather than Novocain (2-4 ml of lidocaine for 1 compress). Lidocaine penetrates the skin better, is less allergic, and its analgesic effect is 2 times stronger.

How to breed ceftriaxone novocaine -
Ceftriaxone is not desirable to be diluted with Novocain, since The antibiotic itself is quite allergic, and Novocain increases the risk of developing anaphylactic shock many times (compared to lidocaine). Optimally dilute ceftriaxone with lidocaine solution (this is also recommended by WHO). This anesthetic is much less allergic, and has a stronger analgesic effect.
Dilute 500 mg of ceftriaxone is necessary in 2-2.5 ml of solvent. For dilution of 1000 mg of ceftriaxone - 3.5-4 ml of solvent. As the latter, either water for injection or a 0.5-1% solution of novocaine can be used, but the best is a 1% lidocaine solution. But to dissolve ceftriaxone in lidocaine, you still have to use water for injection, because lidocaine concentration in ampoules is 2%.
For example, to obtain 1% lidocaine solution for dilution of 500 mg ceftriaxone - you will need to draw 1.0 ml lidocaine into a syringe, then 1.0 ml of water for injection into the same syringe. Then enter the resulting solution into a vial with Ceftriaxone and shake.
Cefazolin: how to plant Novocain
We immediately say that cefazolin is undesirable to be diluted with novocaine, as well as ceftriaxone (for the same reasons). It is also best to use 1% lidocaine solution. To dissolve 1000 mg of cefazolin, 4 ml of 1% lidocaine solution is needed. To get a 1% lidocaine solution, you need to mix 2 ml of lidocaine and 2 ml of water for injection in a syringe by taking turns in both syringes in turn. The resulting solution is introduced into a vial of cefazolin. We hope that our article on the topic: Novocaine instructions for use - was useful to you!
