Anesthesia "Sevoranom": instructions for use, consequences, reviews

"Sevoran" (active ingredient - sevoflurane) is an anesthetic agent that is effectively used in medicine for performing inhalation anesthesia. The introduction of the drug in this way allows you to disconnect the patient's consciousness in a very short time, but everything is quickly restored after the procedure is over.

Anesthesia "Sevoran" with the introduction is accompanied by a slight excitation and slightly noticeable irritation of the mucous respiratory tract. Thus, it is not possible to provoke a strong secretion in the tracheobronchial tree and stimulate the nervous system. The drug provokes a dose-dependent suppression of respiratory function and a decrease in blood pressure.

How is anesthesia going? "Sevor" does not affect intracranial pressure, does not reduce the reaction to carbon dioxide, does not affect the kidneys and liver, does not provoke an increase in deficiency in these organs, even if the patient is anesthetized for a long time. But how correctly to calculate the dosage, so that anesthesia is effective and at the same time safe?

Dosage

Anesthesia "Sevoranom" for each patient is selected individually.

So, during surgery, anesthesia is given by means of an evaporator. Typically, anesthesiologists use special instruments, calibrated precisely for this drug.

Dosage is selected in each case individually. Titration is carried out until the desired effect occurs, while the clinic of the patient, the history of his illness, concomitant diseases and age are necessarily taken into account. After the end of filing "Sevoran" patient is administered a drug from the barbiturate group or another kind of anesthetic, which is designed for intravenous administration to get a deep anesthesia. Usually, oxygen and nitric oxide or "Sevoran" together with oxygen are used for these purposes.

Anesthesia "Sevoran" in a small volume before the operation allows to provide a stage of deep sleep for a couple of minutes, and this applies to both adult patients and children. This anesthesia is characterized by a rapid withdrawal from the anesthesia state without the use of any additional means: patients rarely complain of prolonged depression after this, very quickly restore the functions of thinking, people do not feel any discomfort at the site of the operation and injection.

In addition, narcosis "Sevoran" provides the necessary level of anesthesia. Concentration is selected in the range from 0.55 to 3%, the drug is administered together with nitric oxide.

How is Sevaran anesthetized?

Inhalational anesthesia with this drug, like any other, should be administered to a well-prepared patient - in this way serious consequences can be avoided. The main condition is an empty stomach. Adults are advised not to take food 6-8 hours before surgery, and children - for 4-5 hours. This rule is compulsory for execution, only in this case it is possible to secure the patient, because vomiting may occur, which will lead to such complication as the ingress of vomit into the respiratory system.

Before the patient is taken for an operation, for about a couple of days he is recommended to adhere to dietary nutrition. Only after preliminary preparation can you begin to intervene with "Sevor". The patient is put on a face mask, through which a low-flow gas supply will occur. The patient falls asleep almost immediately, after 1-2 minutes. After the dream has come, the catheter is connected to the peripheral vein, if necessary, it can be intubated. In any operation, even if it is the shortest and easiest, the anesthesiologist follows the patient's condition and adjusts the anesthetic dose so that the depth of anesthesia is necessary. When immersed in anesthesia, the patient passes through several stages:

1. Stunned. It lasts no more than 4 minutes and comes immediately after the person started to give anesthesia. It is characteristic that the patient does not feel pain, but at the same time the consciousness remains. At this stage, doctors perform short surgeries - open abscesses or phlegmon.
2. Excitations. During it, the patient jumps pressure, consciousness and pain are absent, but at the same time, no surgical interventions can be performed during this period.
3. Surgical anesthesia, which is divided into several types of depth:

• surface;
• easy;
• deep;
• Agonal stage - complete paralysis of vital organs.

4. Awakening. At this point, the restoration of all body functions begins.

Features of Sevoran

Anesthesia "Sevoranom" should be used only by professional specialists who have the skills of introducing the patient into this state. At this time, equipment must always be at hand, which will allow applying all the necessary measures to restore passage in the respiratory tract or carry out resuscitation, if unforeseen happen during the operation.

The level of anesthesia when using this particular drug changes very quickly, which forces the anesthetist to use only specially calibrated evaporators. During the deepening of anesthesia, the patient may experience an increase in hypotension and respiratory depression.

If you use a supportive anesthesia, then when the concentration of the drug increases, the pressure will decrease significantly, it directly depends on the dose of "Sevoran". Too sharp and strong decrease in blood pressure can be due to a deep degree of anesthesia.

Consciousness after anesthesia to the patient returns in a few minutes, but even so, the mental faculties will only recover after a couple of hours. Many surgeons and dentists consider one of the best drugs for anesthesia "Sevoran". Instructions for use of this tool states that the action occurs almost instantaneously, and the patient leaves the state of anesthesia quickly, in most cases without consequences, although sometimes they do happen.

Advantages of using Sevoran

It should be noted that this drug, intended to introduce a person into a state of anesthesia, has a number of undeniable advantages:

• Rapid immersion in anesthesia (almost immediately after the first inspiration), as well as a quick exit - no more than 20 minutes after the drug is stopped.
• Almost does not affect the respiratory system, heart and blood vessels.
• High degree of controllability.
• The lowest degree of irritation of the respiratory system.
• Not toxic to the patient's body.
• Thanks to an excellent anesthetic effect, anesthesia is effectively used in dentistry And when performing cavitary operations.
• A rare manifestation of undesirable consequences.
• Possibility of using in the form of mononarcosis.
• It makes it possible to use low-flow anesthesia, which causes a minimal consumption of the drug, a complete absence of environmental contamination with drug vapors.

All the advantages described above suggest that the preparation is very effective and has almost no consequences, therefore it is often used when anesthetized teeth are treated in adults and children, as well as in other surgical procedures.

Side effects and contraindications

But it is worth remembering that any drug has contraindications and side effects, and all this is due to the characteristics of the organism of each patient. You can not predict how the drug is perceived by the body. Even the most harmless drugs can cause serious consequences for some people, this also applies to anesthesia.

• Dizziness, drowsiness, convulsions, sudden mood changes - these symptoms can occur within a couple of days after anesthesia.
• Respiratory disorders, cough.
• Arterial pressure jumps, tachycardia, or bradycardia.
• Nausea, vomiting.
• Allergic reactions.
• Chills and fever.

In addition to side effects, in rare cases "Sevoran" (instructions for use about this also informs) has contraindications, and every patient must know about them before anesthesia is required. Among the contraindications:

• Special sensitivity to the drug.
• Genetic predisposition to the occurrence of malignant hyperthermia.
• Breastfeeding period.

Also, all means for inhalation anesthesia are recommended for use with extreme caution in patients with renal insufficiency, intracranial hypertension, coronary heart disease and neuromuscular pathologies. Children are allowed to use "Sevoran", but only in a reduced dose and under the supervision of a doctor, even after quitting anesthesia.

Overdose

In case of an overdose, the patient may have symptoms such as:

• The activity of the central nervous system is changing.
• Hypotension.
• Collapse of blood vessels.
• Convulsions.
• Stop breathing.

If such symptoms appear, then it is necessary to stop the drug immediately, install a clean breathing tube and start artificial ventilation with oxygen, monitor the work of the heart, if you need to introduce drugs to maintain it.

Interaction with other drugs

Inhalation anesthesia is perfectly combined with drugs, which are often used by surgeons during surgery. This applies to drugs that affect the nervous system, muscle relaxants, antibacterial drugs, hormones, blood products. There were no undesirable interactions.

Special instructions for use

"Sevor" can not be used independently at home. This drug should be administered, the dosage should be selected and the patient's condition monitored only by anaesthesiologists, preferably those who have experience in general anesthesia.

To provide funds for inhalation anesthesia, especially for the drug "Sevoran", you need to use calibrated evaporators. It is also necessary to inform the patient that after anesthesia, he can not sit down for a while driving and work with any moving mechanisms, because concentration of attention can be disturbed.

Features of the application of "Sevoran" in the treatment of teeth in children

If the teeth are treated under anesthesia, Sevoran is allowed to be used by both adults and children. In addition, this type of anesthesia is also often used in other operations for children:

• Urgent surgical intervention for acute inflammation in the oral cavity (abscess, periostitis).
• Planned operation (extraction of teeth, cysts).
• Pulpitis, multiple caries and periodontitis.

But not always dentists in the treatment of teeth in children use inhalation "Sevoran". Anesthesia for the children treated by us is indicated in such cases:

• If there are contraindications to the use of local anesthetics.
• If the child is not contact (pronounced negativity towards dentists).
• There are organic pathologies of the nervous system, during which the child can not really assess the surrounding reality.
• If it is necessary to urgently perform a one-stage sanation of the oral cavity with a large volume of manipulation.

But it is worth remembering that any child perceives any drug very sensitively. Parents should inform the doctor about the presence of the following conditions in the baby, which are contraindications to narcosis by means of "Sevoran". Consequences can otherwise be the most serious. So, do not recommend it:

• With inflammation of the upper tract.
• In acute inflammatory processes of the urinary tract, liver, lungs.
• If there is exudative diathesis.
• Recent infections.
• High intracranial pressure.
• Decompensated pathologies.
• If there is no possibility to use local anesthesia.

Of course, the child must necessarily be prepared for the introduction of anesthesia "Sevoran". Dental treatment under general anesthesia is carried out not only during tooth extraction, but also in other cases, and each procedure must be properly prepared:

• To pass or take place inspection - to hand over a blood, urine, biochemistry.
• ECG.
• Conclusion pediatrician (in the certificate should be indicated that the patient has no contraindications to the use of this type of anesthesia).
• Anesthesia is injected only on an empty stomach.

Currently, there are a lot of varieties of drugs for anesthesia, but recently the popularity of "Sevor" American company. It is considered the most harmless for the body, it is well tolerated by both adults and children. He has a very pleasant aroma, which the children inhale and do not feel any discomfort.

The effect occurs immediately, immediately after a couple of breaths, and the patients wake up 15 minutes after the end of the drug. This effect is due to the fact that more than 90% of the drug is excreted through the lungs in unchanged form. The patient inhaled the drug, and after 10-15 minutes it can not be found in the blood. It is excreted very quickly from the body, with no organs from its effects do not suffer, the allergy does not cause.
