Articaine with adrenaline

Modern anesthesia in dentistry guarantees complete pain relief during the entire treatment. Visiting a dentist at all Dental Guru clinics is absolutely comfortable. Before treatment, the desired area will be completely numbed. If you feel discomfort during the manipulations, immediately inform your doctor, and he will add anesthesia if necessary. All instruments in our clinics are sterilized in accordance with modern standards; doctors work in disposable masks and use disposable syringes.

It should be taken into account that drugs for anesthesia in dentistry differ in the content of adrenaline. And if you suffer from hypertension, high blood pressure, or various allergic reactions to any medications, please do not hesitate to inform your doctor about this in order to avoid unpleasant situations.

Types of anesthesia in dentistry

Anesthesia is divided into local and general. These types of anesthesia in dentistry are divided, in turn, into subtypes. Local anesthesia in dentistry can be application (superficial) and injection. Application anesthesia

in dentistry it is performed before an injection. This is the application of a gel, ointment or spray. The effect of such anesthesia occurs instantly, after which the injection itself is not felt.

Application anesthesia lasts up to 20 minutes and allows the hygienist, therapist or surgeon to perform simple manipulations, for example, removing tartar or suturing a gap. For superficial anesthesia in dentistry, drugs such as dicaine, lidocaine and anesthesin are used. Indications for local anesthesia in dentistry are treatment of caries, tooth extraction, oral surgery and other dental procedures.

Injection anesthesia in dentistry

There are 4 types:

• infiltration;
• conductor;
• intraligamentary (intraligamentous);
• intraosseous

Infiltration anesthesia in dentistry

used most often in the treatment of caries and tooth extraction. The doctor injects painkillers using a syringe with a thin short needle. The injected anesthetic blocks the transmission of impulses from the nerve endings of the anesthetized area.

Types of infiltration anesthesia in dentistry differ according to the area of ​​influence: lower or upper jaw, intraligamentary, intrapapillary, subperiosteal. With intragalimentary anesthesia, an anesthetic is injected into the ligaments of the tooth. The drug is delivered under high pressure into the bone of the alveolar ridge. During intrapapillary, the drug is injected into the papilla between the teeth, and during subperiosteal, the needle enters between the base of the root and the gum.

Conduction anesthesia in dentistry

is performed by injecting an anesthetic at a distance from the desired area, thereby blocking the transmission of nerve impulses to parts of the nerve fiber. Numbs a large area with one injection of a small amount of the drug.

Types of conduction anesthesia in dentistry:

For the upper jaw, there are the following types: infraorbital (anesthesia of canines, incisors and premolars), tuberal (for molars), palatal, incisive (incisors and canines). For the lower: mandibular (the half of the jaw in which the injection is made is anesthetized), Bershe-Dubov technology (long-lasting, used for maxillofacial operations), torusal (for premolars and molars), mental (for incisors, canines and premolars).

For intragalimentary (intraligamentous) anesthesia, a special syringe is used. A small amount of painkiller is given slowly, under pressure, the number of injections corresponds to the number of tooth canals that need to be treated. Such injections are almost painless, sensitivity is eliminated instantly. Intragalimentary anesthesia acts locally, and there is no numbness of the tongue, lips and mucous membranes, and there are no problems with diction. This method is suitable for patients with cardiovascular and endocrine diseases, as well as children.

Intraosseous anesthesia is performed when treating complex teeth. The anesthetic is injected into the bone, completely removing the sensitivity of the tooth. A special syringe is used, with a rotating bur. In addition to the complex tooth, the anesthesia covers the area of ​​two adjacent teeth, gums and roots, and “freezing” does not occur. Mainly used for complex extractions, including wisdom teeth, caries complications, restorations and periodontal surgeries.

All types of local anesthesia in dentistry are similar in the drugs used, but differ in the method of their administration (or application). Methods of local anesthesia in dentistry are selected for each patient individually, based on the time and area of ​​exposure, as well as the specifics of the procedure being performed. The answer to the question of which anesthesia is best in your case can only be given by a qualified specialist.

Anesthetics without adrenaline

This group of anesthetics includes Scandonest and Mepivastezin (Mepivacaine).

They have a moderate vasodilator effect, so they are used without a vasoconstrictor. After administration of the drug, anesthesia occurs quickly (3–5 minutes), the effect lasts 3–40 minutes for pulp anesthesia, and up to 3 hours for soft tissue anesthesia. It is used for all types of manipulations, as well as during maxillofacial operations. Indicated for children weighing at least 15 kg.

Scandonest has the following side effects:

• headaches, dizziness;
• change in heart rate;
• allergic reactions;
• hypotension;
• disturbances in the gastrointestinal tract.

For patients with a complicated medical history, the elderly, pregnant and lactating women, the drug is prescribed with caution, as it penetrates into the blood.

It poses less danger during infiltration anesthesia (the drug is injected directly into the site of the intended manipulation).

Ultracaine (Articaine) is used for local and general anesthesia and is considered a leader.

It is reliable and is used for pain relief in children, the elderly and pregnant women.

There are 3 versions of the drug available:

• Ultracaine D, which does not contain preservatives and epinephrine;
• Ultracaine DS, with epinephrine;
• Ultracaine DS forte, with increased vasoconstrictor content.

Ubistezin is similar to Ultracain in composition and properties. Suitable for patients of all ages, except children under 4 years of age. The effect of the drug appears 1-3 minutes after injection and lasts 45-240 minutes - this depends on the type of anesthesia. The patient's health status dictates the choice of drug form.

Both drugs labeled “D” (without adrenaline) are used for the following diseases:

• bronchial asthma;
• tendency to allergies;
• thyroid diseases;
• diabetes;
• hypertension;
• cardiac decompensation.

For high blood pressure, moderate heart disease, and pregnant and nursing mothers, Ubistezin and Ultracain labeled “DS” can be used, since a low concentration of the vasoconstrictor will not cause as much harm as the penetration of the anesthetic into the blood.

General anesthesia in dentistry

Sedation is used for general anesthesia in dentistry. What it is? Sedation is a drug-induced sleep during which all reflexes are preserved, the patient can turn his head and open his mouth wider. If necessary, it can be quickly removed from this state. During sedation, a large number of teeth can be treated without discomfort. An anesthesiologist is constantly in the office; pulse, blood pressure, ECG, and blood oxygen saturation are monitored. After the operation, the patient feels only slight drowsiness and relaxation, there is no pain. This method is optimal in the presence of severe fear, hypertension, allergies to any type of anesthesia, and is suitable for children.

Contraindications to anesthesia

Contraindications to local anesthesia in dentistry: allergies to any drug, cardiovascular and endocrine diseases, bronchial asthma, liver failure, taking beta-blockers, tricyclic antidepressants, mental illness, recent coronary bypass surgery, trauma to the maxillofacial area .

Temporary contraindications to dental operations under anesthesia:

• drinking alcohol on the day of surgery or the day before;
• colds;
• period of menstruation in women due to deterioration of blood clotting.

Anesthesia for bronchial asthma

in dentistry requires special knowledge and training from the doctor. This is one of the cases when safe anesthesia in dentistry is necessary.

If a patient with bronchial asthma needs dental treatment, before starting the procedures, the dentist will refer him to an allergist to clarify the status and contraindications. It is necessary to clarify what medications the client is using. In this case, before treatment, premedication is mandatory, either as prescribed by the allergist, or, in the absence of these, with Xezazal 5 mg, Zyrtec 10 mg or Kestin 10 mg 5 days before surgery, on the day of admission and 5 days after, 1 tablet 1 once a day. Immediately before dental procedures, you need to inhale a fast-acting drug from the salbutamol or fenoterol group (Ventolin, Berotec).

If an attack of suffocation develops, at the beginning of which chest pain, coughing or sneezing appears, then the inhalation shortens, the exit lengthens, wheezing is heard, the patient becomes anxious and cannot speak. The patient leans forward, rests his elbows on his knees, turns pale, sweats, and his lips turn blue. Exhalation is difficult. During an attack, the doctor should open the windows to allow fresh air in, if there is contact with the allergen, exclude it, give warm water to drink, and help inhale the medicine from the inhaler.

For bronchial asthma, an anesthetic without preservatives, for example, Ultracaine D, is best suited. Acetylsalicylic acid and other substances that provoke bronchospasm, such as morphine and indomethacin, are contraindicated.

Storage conditions

Septanest should be stored in a dry, dark place, at a temperature of no more than 25 °C. The solution should not be frozen, nor should it be left in direct sunlight or near heating sources.

Local anesthesia is a reliable and proven method that allows dental procedures of any complexity to be performed completely without pain and with maximum comfort for the patient. "Septanest" is one of the representatives of this category of drugs, the effectiveness and safety of which has been repeatedly proven clinically and in practice.

Features of anesthesia for pregnant and nursing mothers in dentistry

Pregnant women definitely need to have their teeth treated, because caries or other inflammatory processes in this area are a threat to the health of the baby. Treatment with special anesthesia, tooth extraction, removal of plaque and stone, and rinsing according to doctor’s indications are allowed. Implantation, x-rays, the use of dental gels and ointments without medical advice, and the unauthorized use of antibiotics and painkillers without a doctor’s prescription are prohibited. Prosthetics and orthodontic treatment during pregnancy are questionable. Various complications and inflammations may occur, which are especially dangerous during this period.

The second trimester is the most favorable for dental treatment - there is no toxicosis, the formation of the main organs and systems of the fetus is behind. If you suffer from toothache, there is no need to postpone treatment at any time during pregnancy; the doctor will select a special anesthesia. Pregnant women often have gingivitis (inflammation and bleeding of the gums, severe sensitivity), which must be treated. Without treatment, the risk of premature birth increases up to 6 times. In the last trimester, dental treatment is especially dangerous; any stress can trigger labor before term.

Anesthesia in dentistry during pregnancy is characterized by the use of anesthetics without adrenaline (it can cause uterine hypertonicity). Articaine drugs are used, for example, primacaine and ultracaine. These substances do not penetrate the placenta, but at the same time they provide excellent pain relief, soothe inflammation of the oral cavity, and are hypoallergenic. Similar anesthesia in dentistry is also used during breastfeeding.

Release form and composition

The solution is available in 1.7 ml injection cartridges - they look similar to standard syringes, only the needles in them are many times thinner. This feature allows the injection to be performed with minimal discomfort for the patient. The drug is presented in two concentrations of the active substance: 1:100,000 and 1:200,000. The price, which varies from 1,500 to 2,000 rubles, also depends on this indicator.

The drug contains articaine and epinephrine

As mentioned above, Septanest contains articaine and epinephrine, as well as auxiliary components such as sodium hydrochloride, sodium bicarbonate and water. For comparison: articaine is 2 times more effective than lidocaine, and novocaine is 6 times more effective1.

Thanks to this composition, Septanest not only blocks pain receptors and neuromuscular transmission, but also affects blood supply. Epinephrine reduces the rate of penetration of articaine into the vascular bed, thereby providing a longer lasting analgesic effect. In this case, the drug is quickly excreted by the kidneys.

Modern drugs for anesthesia

The choice of anesthetic depends on the patient's individual treatment plan and the method of anesthesia. For local topical anesthesia, gels, ointments and sprays based on lidocaine, dicaine, bumecaine, and benzocaine are currently used. For example, diplen - LH, topex gel, disilane, diseptin, xylonor.

For injection anesthesia, drugs such as procaine, lidocaine, mepivacaine, ultracaine, ubistezin, trimecaine, articaine, chirocaine, bipuvacaine are used. Inhalational sedation uses a mixture of nitrous oxide and oxygen. If you are afraid of visiting the dentist, you can take tranquilizers orally in the form of tablets, for example, diazepam, oxazepam, hydroxyzine, hexobarbital, as prescribed by the doctor.

Instructions for use

According to the instructions, the solution is intended for injection into the area of ​​pain relief, half or a whole cartridge, depending on the patient’s weight and the complexity of the upcoming procedure. The drug is not suitable for intravenous administration. Before opening the sealed package, wipe it with 96% alcohol. The cartridge must be disposed of after use.

For simple tooth extraction in the absence of an inflammatory process, 1.7 ml is injected under the mucous membrane. For additional pain relief, another 1-1.7 ml can be injected. To prepare carious cavities and grind crowns for single dentures, a vestibular injection of 0.5-1.7 ml is performed for each tooth (with the exception of lower molars). The maximum permissible dosage is 7 mg per 1 kg of weight.

Electronic anesthesia in dentistry

This is a technique of anesthesia in dentistry in which the rate of administration of the anesthetic is under electronic hardware control. The anesthetic is delivered dropwise, without injury or stress, the needle moves smoothly. The advantages of using an anesthesia device in dentistry are the absence of pain, fast response (two minutes for pain relief), complete patient comfort (no discomfort before, after, or during the process), and accuracy of the injection.

Dental Guru clinics use an innovative method of computer anesthesia using the MEG-INJECT device, which allows you to accurately calculate the dose of the drug and the speed of its delivery. A thin needle ensures painless injection; application anesthesia is not required before the injection.

Drugs with similar effects

Septanest analogues are usually interchangeable because they have a similar composition. However, each has its own application characteristics, so the choice of the appropriate product remains up to the specialist. Among the popular anesthetics similar in action to Septanest, experts identify the following drugs:

• "Artifrin"
• "Artikain"
• "Artifrin"
• "Bupinecaine"
• "Ubistezin" etc.

"Ubistezin" is a high-quality modern anesthetic.
So, “Bupinecaine” is cheaper. It contains the same active ingredients, but in a different combination. This drug is also widely used for epidural and spinal anesthesia, that is, its scope is much wider. But “Artifrin” has a less pronounced anesthetic effect, therefore it is not used when working with inflamed soft tissues and in surgical practice.

Anesthesia without adrenaline in dentistry

Why is adrenaline needed in painkillers? It enhances the effect of the anesthetic by constricting blood vessels and capillaries, so that the anesthetic is concentrated at the injection site. In addition, adrenaline reduces bleeding, so drugs with adrenaline are optimal for operations with large blood losses. The most commonly used drugs with adrenaline are ultracaine, ubistezin and alfacaine.

Adrenaline anesthetic will not harm a healthy person. But if you have cardiovascular diseases (heart attack in the next six months), endocrine disorders (diabetes mellitus) or pregnancy, then adrenaline should not be used. Therefore, anesthetics such as lidocaine, pyromecaine, bupivacaine, trimecaine, prilocaine, and articaine are used. Non-adrenaline anesthetics begin to act more slowly than adrenaline ones, and their effect ends faster. At the same time, the safest anesthesia in dentistry is adrenaline-free.

What is Adrenaline

Adrenalin is a hormone of the adrenal medulla.

It is usually obtained from the adrenal gland of cattle, and also synthetically from pyrocatechol. In addition to free adrenaline, various compounds can exist in the body.

The effect of adrenaline on the body causes reactions similar to the phenomena observed during stimulation of the sympathetic nervous system, accompanied by the release of sympathins - chemical mediators (conductors) of sympathetic nerve impulses.

Adrenaline is highly active in minute concentrations.

In medical practice, a solution of hydrochloric salt of adrenaline (Adrenalinum hydrochloricum solutum) is used in a concentration of 1: 1000.

The main pharmacological effect of adrenaline is the stimulation of the sympathetic nervous system (constriction of blood vessels in almost all areas of the body, with the exception of the vessels of the lungs, increased blood pressure, relaxation of the tone of the bronchial muscles, etc.). The use of adrenaline together with anesthetic substances in surgical practice is based on its local vasoconstrictor effect.

Adrenaline itself does not have any analgesic power, but only causes, as mentioned earlier, a narrowing of small vessels and capillaries.

It should be noted that the high concentration of adrenaline used by some practitioners for conduction and infiltration anesthesia in dental practice - 1 drop (1: 1000) per 1-2 ml of novocaine solution sometimes causes unpleasant phenomena even without the solution entering the vein: heartbeat, increased pulse rate, dizziness, fainting and sometimes even collapse. Slow injection of a fresh adrenaline solution heated to body temperature significantly reduces the toxic effect of the drug.

A weaker concentration of adrenaline during conduction and infiltration anesthesia in the dentofacial area (1 drop per 5-15 ml of solution) is less likely to cause unpleasant phenomena associated with the toxicity of the substance.

There are, however, people who are very sensitive to adrenaline and even when injecting the slightest dose of it, they react with general toxic phenomena (increased pulse, palpitations, pale face and even collapse).

Many times they tried either not to use adrenaline at all, or to replace it with less toxic substances, such as eserine, ephedrine, etc. But the elimination of adrenaline led to a decrease in the analgesic effect and to an increase in the toxicity of the anesthetic.

It should only be emphasized that for pain relief, adrenaline must be added to the anesthetic substance in the weakest concentrations. For conduction anesthesia, one drop per 5-10 ml of anesthetic solution is sufficient, and for infiltration anesthesia, one drop per 10-15 ml of solution is sufficient. When it is necessary to use a large amount of anesthetic solution, take one drop of adrenaline (1: 1000) for an even larger amount of anesthetic solution (one drop per 20-25 ml).
