Extensive and uncomfortable dental treatments are only workable for many patients afraid of the dentist. Help for those people come in dentistry sedation dentistry! What is the difference between local and general anesthesia? What is the procedure of sedation dentistry and what risk coming with it, find more out here?
Difference between local anesthesia and general anesthesia
There is different anesthesia to avoid pain during dental treatment: Local anesthesia, and general anesthesia.
The dentist performs local anesthesia much more frequently than general anesthesia. This is a local anesthetic with a suitable anesthetic to eliminate the pain at a localized treatment site. The patient remains conscious and is not impaired in his perception – depending on the anesthesia; they prevent the transmission of pain to the brain. So, the pain does not even arrive and also is not noticed.
Popular anesthetic procedures for dental procedures
Anesthetics given intravenously (injection into a blood vessel / vein) comprise sleeping pills (hypnotics), highly effective pain relievers (analgesics) and muscle relaxants (muscle relaxants).
Laughing gas as an anesthetic
Another possibility is inhalation narcotics, which supplies through the breath. These are gases with a narcotic effect, such as laughing gas or vaporizing liquids, which have a hypnotic and muscle-relaxing effect.
Laughing gas (N2O) has been used in dentistry since the 19th century and is therefore one of the oldest anesthetics. It has been used millions of times every day in world dental practices and has the advantage that the patient does not lose consciousness and thus remains responsive during the treatment. In addition, we can carry out the treatment with nitrous oxide without the presence of an anesthetist.
Twilight sleep – analgesic sedation as an anesthetic
An excellent alternative to anesthesia is “analgosedation” at the dentist, in which it does not put people into deep sleep, but only into twilight sleep. The word analgosedation is composed of analgesic (pain reliever), and sedation (sedative).
What happens to my body under general anesthesia?
In contrast to local anesthesia, with general anesthesia it temporarily put the person to be treated into a state of deep sleep with medical anesthetics – the consciousness, the pain sensation, and certain bodily functions in the entire body are temporarily “paralyzed”.
Deep anesthesia has the following advantages:
· the dissolution of consciousness in the form of sleep
· the elimination of the sensation of pain, the blockage of the memory
· the dampening of vegetative nerve functions
· the muscle relaxation
Because of the memory block, there is no memory of the course and events of the surgical intervention, which is the desired effect. The attenuation of the vegetative functions affects, for example, blood pressure, pulse, bowel activity, and changes in body temperature. In the artificial sleep state, the consciousness, muscle strength, the respiratory drive and many protective reflexes of the body are suspended.
The process of general anesthesia
General anesthesia at the doctor divides into three phases: the falling asleep phase, the maintenance phase, and the waking up phase.
The informative talk with the anesthetist
Before all of this happens, there is an informative discussion with an anesthetist. He/She is at the patient’s side even during the ongoing anesthesia and always monitors treatment and the values of the sleeper. The informative discussion with the anesthetist deals with the general risk of anesthesia and the risks that the planned treatment may involve.
The sleep phase
Before the operation begins, the doctor will give you a sedative. After the calming effect has set in, they start the actual anesthesia. Everyone presents takes care of the patient, while the patient can fall asleep quietly. The treatment is already being prepared in the background and all instruments checked and the treatment team, comprising nurses, assistants, and doctors, briefly discuss the process and the specific features again.
The maintenance phase
Depending on the type and extent of the procedure, doctor apply an oxygen supply after falling asleep. The sleeper will notice none of this – and he will not remember either. The only thing you may notice after ventilation is a scratchy or dry throat. During the treatment, the anesthetist makes sure that the person does not wake up and remains in a deep sleep by constantly giving anesthetics.
The waking up phase
After the treatment is complete, the supply of anesthetic reduce further, and the wake-up phase is initiated. Just like after a deep sleep, you need time after a general anesthetic to find yourself and the world again – but the specialist staff will accompany you. After the patients have come to, they often remain in the practice or clinic for observation for a certain period. This ensures that the patient is fine, that he has tolerated the anesthesia well and that there are no post-operative impairments because of the anesthesia. You can now go home with a companion.
General anesthesia: risks and side effects
A general anesthetic at the dentist is a very safe procedure. There are certain risks and side effects when the body has been put into a deep sleep.
Risks: previous illnesses, allergies, or pregnancy?
The dentist and anesthetist examine the patient’s state of health and medical history before starting the treatment. If, for example, there are any serious previous illnesses, previous operations, chronic diseases (such as those relating to the lungs, heart, liver, thyroid, brain or blood), current concomitant diseases, pregnancy, intolerance and allergies to anesthetics or other crucial issues, general anesthesia may not be the option because of risks considered.
Risk: Age and lifestyle such as alcohol, smoking, drugs, and some medications
The extent to which general anesthesia at the dentist’s is too risky to assess individually by doctors, as is the suitability of the anesthesia and the anesthetic and pain relievers. If there are certain risks for general anesthesia that represent an exclusion criterion, local anesthesia can still solve the problem of pain sensation.
Who is deep sleep treatment suitable for?
There is nothing in the way of general anesthesia for patients in good health. In principle, any healthy person can undergo medical treatment under the influence of anesthesia, from children from 2 years to older people.
The decisive requirement is always the state of health
A deep sleep anesthesia represents a significant effort and a high burden on the body. It should be considered that there are always risks, side effects or health consequences associated with it. The financial aspects can also represent a hurdle because the procedure involves corresponding costs that are not always borne by the health insurance company, but for which the patient must pay himself.
