Colonoscopy under General anesthesia (in a dream) without pain: preparation, conduct

 

Colonoscopy is a highly informative study of the large intestine, which has practically no «competitors» – even radiological imaging techniques are not able to replace this endoscopic procedure. However, colonoscopy is associated with unpleasant and even painful sensations in the patient. So usually protect the examinee from them with the help of painkillers and sedatives. This applies to anesthesia, sedation or a colonoscopy with anesthesia.

Anesthesia for colonoscopy is used most often. To spend the colonoscope through the rectum, doctors use local anaesthetics. And to prevent pain during the passage of the bends of the colon – the usual intravenous anaesthetics and spasmolytic drugs, which in the absence of gross pathology of the large intestine is sufficient for adequate anesthesia. In some cases, sedation during colonoscopy is still required, but indications for such training is prescribed by your doctor. Another method of analgesia during colonoscopy is the anesthesia. When and to whom shown the epidural anesthesia and sedation we describe next.

The main contraindications to this examination is for shock, heart attack/stroke, respiratory failure, peritonitis.

When indicated anesthesia?

Colonoscopy under anesthesia is not performed in each case. Anesthesia is used according to indications and not according to the desire of the patient.

  • Children up to 12 years. Compulsory pre anesthesia. This is due to the fact that the pain the study may cause injury to the immature child’s psyche, resulting in phobias in adult life. Pain medications are selected individually.
  • Multiple adhesions that develop as a complication after extensive abdominal operations, and hinder the free passage of the colonoscope causing intense pain – the anesthesia during a colonoscopy eliminates pain, allowing the doctor to carefully examine the intestines throughout.
  • The vast destructive processes in the colon requiring colonoscopy, it is better to accompany General anesthesia this colonoscopy is more effective.

Colonoscopy under anesthesia can make people with a low pain threshold. This point is determined by the attending doctor individually, because in these patients a similar study can cause a state of shock.

Your doctor may use several methods to conduct a study painless. Besides the fact that doing a colonoscopy with General anesthesia, the doctor may use and sedation. In both cases, possible colonoscopy without pain and unpleasant memories.

Sedation

If assigned to the examination, sedation is considered as a reliable method is good analgesia of the patient. Using intravenous injection of special funds, the anesthesiologist puts the patient to superficial sleep. Usually used the same drugs, and for sedation during surgery in a hospital. As a result, when colonoscopy bowel the person is not in pain and completely relaxed physically. This greatly simplifies the course of the study, making it as informative as possible.

Along with the lack of pain and emotion, the patient remains conscious and able to respond adequately to questions and requests of the doctor.

This minimizes the risk of injury to humans, and enables the physician to ask them to change the situation – this need occasionally arises. Right sedation does not cause respiratory depression, and memories of study may be absent altogether – this effect is observed in 80% of the people who were immersed in a medicated sleep.

Among the disadvantages of this method should be noted:

  • allergic reactions to medications, but the risk is minimal if the preparation for the colonoscopy was carried out by a competent specialist;
  • side effects medicines in the form of nausea, vomiting, headaches;
  • intestinal perforation is a rare complication associated with suppressed sensitivity to pain of the patient and little experience of the doctor conducting the study.

Currently, the risk of negative consequences is reduced to zero as a colonoscopy in a dream is carried out on modern equipment, in the presence of an anesthesiologist.

Anesthesia

Anesthesia completely disables the mind of a person who is no longer able to interact with the doctor, and after the procedure in 100% of cases, there is complete amnesia. What anesthesia to give the subject, is it possible to use it at all, and what extent it needs to be, depends on the condition of the patient, and solved by the doctor individually. To him there are obvious contraindications, among which should be noted:

  • decompensated pathology of the cardiovascular system is to do a colonoscopy can, but more often it is conducted under a different type of anesthesia;
  • severe disease of the respiratory system;
  • acute neurological diseases.

In childhood to the list of contraindications is added causeless temperature rise, malnutrition, rickets, generalized pustular skin lesions of acute infection. In this case, you can either sedation or delay the procedure.

Colonoscopy bowel under anesthesia is used rather seldom, because without a very serious medical indications to use doctors fear – there is always a danger of serious complications. They may be associated with the use of potent medicines, and with increasing risk of perforation of the colon. It is understood that such a study, under General anesthesia, requires very careful preparation.

If the fault of the patient, conducting the colonoscopy will be impossible what happens with poor diet, the doctor may refuse to study. It should be considered, especially those who are shown to sedation or anesthesia – re-introduction of strong drugs can take a long break, which is not always desirable.

Preparing for colonoscopy

Order went through without a hitch, and was as informative as possible, you should prepare carefully. The doctor or nurse will give very clear recommendations that are binding. Conducting a colonoscopy under General anesthesia requires a thorough bowel preparation, which starts 2-3 days before the study. A special role is played by the diet – what foods and how many of them can be used to tell the specialist. The task of the patient strictly follow the recommendations because of the purity of the gut depends on the performance of the study. The degree of analgesia during colonoscopy does not depend on dieting, but if the stool is too large, the doctor may simply not notice a dangerous pathology, so the preparation should be treated extremely carefully.

Do we need anesthesia?

If there is no clear medical evidence, the examination is best done without anesthesia. So the risk of various complications from the procedure will be minimal. All the unpleasant or painful sensations during the studies are of short duration and did not differ in intensity. In addition, after pumping air, and at the end of the procedure, they are themselves.

When expressed as fear of the procedure or pathological fear of pain is better to choose a sedation – it requires the use of smaller concentrations of medicines, is better tolerated by the body. Continued during the study contact with the patient allows you to more carefully inspect the intestines by changing the position of the patient’s body. The absence of anesthesia does not allow the doctor accidentally damage the intestines, a perforation will require urgent surgical intervention.
