The tracheal tube exchanger is a hollow catheter, 56 to 81 cm (22.0 to 31.9 in) in length, that can be used for removal and replacement of tracheal tubes without the need for laryngoscopy. [22] The Cook Airway Exchange Catheter (CAEC) is another example of this type of catheter; this device has a central lumen (hollow channel) through which ...
It channels oxygen and inhalational anaesthetic to the lungs. It can be used during anaesthesia, or while a patient is unconscious. Laryngeal mask airways are designed to be an easy way to secure the airway and ventilate a patient – they are easier to place than tracheal intubation due to the lack of muscle relaxants and laryngoscopy.
General anesthesia is usually considered safe; however, there are reported cases of patients with distortion of taste and/or smell due to local anesthetics, stroke, nerve damage, or as a side effect of general anesthesia. [46] [47] At the end of surgery, administration of anaesthetic agents is discontinued.
This procedure is used where general anesthesia must be induced before the patient has had time to fast long enough to empty the stomach; where the patient has a condition that makes aspiration more likely during induction of anesthesia, regardless of how long they have fasted (such as gastroesophageal reflux disease or advanced pregnancy); or where the patient has become unable to protect ...
The most widely used route is orotracheal, in which an endotracheal tube is passed through the mouth and vocal apparatus into the trachea. In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Alternatives to standard endotracheal tubes include laryngeal tube and combitube.

An inhalational anesthetic is a chemical compound possessing general anesthetic properties that is delivered via inhalation. They are administered through a face mask, laryngeal mask airway or tracheal tube connected to an anesthetic vaporiser and an anesthetic delivery system .
Additionally, a breathing tube is provided for the patient, which is inserted into the nose instead of the regular breathing tube for the mouth in order to have enough space in the mouth for the surgery to be conducted in a safe and precise manner. The operation commences immediately after the patient has fallen asleep from the anesthesia.
Tracheotomy tubes and endotracheal tubes are often attached to ventilators to assist in breathing. In the chronic (long-term) setting, indications for tracheotomy include the need for long-term mechanical ventilation and tracheal toilet (e.g., comatose patients, extensive surgery involving the head and neck).
