You will be undergoing a surgical intervention which is not painless therefore it is performed under general anaesthesia or analgosedation. This will be provided by the specialised doctor – anaesthesiologist who will take care of you in the immediate pre-operation period, during the surgical procedure and if necessary, he/she will take of you during the postoperative period. The anaesthesiologist will discuss with you the method of anaesthesia and will inform you about its advantages, disadvantages, possible risks and possible complications. Please, read carefully the following information and answer accurately and thoroughly the questions concerning the state of your health so that your doctor – anaesthesiologist can choose for you the safest method of anaesthesia.
General anaesthesia (narcosis, „put to sleep“) is the state consisting of unconsciousness and lack of pain similar to sleep. The means called anaesthetics or narcotics used to induce this state can be administered by the following ways:
- Anaesthetics can be injected in the vein = intravenous anaesthesia. The intravenous cannula is used for application of fast working anaesthetics which can be administered repeatedly or continuously in case of the surgery lasting for a longer period.
- Anaesthetics are administered by inhalation = inhalation anaesthesia. The mixture of oxygen and air or mixture of nitrous oxide and vapour-creating anaesthetics is brought to the lungs.
Both methods can be combined or they might complement each other. During anaesthesia, the anaesthesiologist ensures patency of airways: at the beginning of anaesthesia by the face mask which firmly leans on the face around nose and mouth, and during general anaesthesia airways management is performed by inserting a special tube through oral cavity to larynx – laryngeal mask or so-called intubation tube is inserted through oral cavity between vocal ligaments to windpipe. Both techniques maintain airways free for supply of oxygen and inhalation anaesthetics, decrease a risk of saliva and gastric content aspiration during the surgical intervention. After inserting the intubation tube it is always necessary to use substances – muscle relaxans which completely eliminate muscle tension and cause arrest of volitional breathing.
During anaesthesia you will be permanently monitored clinically and by devices. The obtained data are regularly evaluated and recorded in the report on the course of anaesthesia.
Analgosedation is the state induced by administering tranquilizing medications – sedatives and medications relieving pain – analgetics. This state is characterized by larger or lesser sedation of the consciousness and removes fear and pain perception. Administered sedatives can induce amnesia which is the state when an operated patient does not remember the course of the performed intervention. Sedatives and analgetics are administered intravenously.
