Does human anesthesia require spontaneous breathing?
When the patient's spontaneous breathing is well recovered, consciousness is completely awake, good ability to speak, vital signs are stable, that is, anesthesia wake up from the room standard, they can return to the ward.
General anesthesia is not required for tracheal intubation, mechanical ventilation. Some time is short, nociceptive stimulation is small, simple surgical operation and examination operation, such as abortion, gastrointestinal examination, etc., do not need tracheal intubation general anesthesia, and can be carried out to retain spontaneous breathing, but the disappearance of general anesthesia The
Then enter the anesthesia maintenance state, the anesthesiologist through the anesthesia machine to the patient inhalation of anesthesia gas, or through intravenous infusion of narcotic drugs, so that patients continue to be in anesthesia. At this point you can start the operation. The length of the entire anesthesia maintenance time depends on the length of the operation time. Surgery for a long time, anesthesia to maintain a long time; short operation time, anesthesia maintenance time is short. When the surgery ends smoothly, the anesthesiologist will stop the use of narcotic drugs, the patient enters the anesthetic recovery period. With the patient's body anesthetic drug metabolism, the concentration of narcotic drugs gradually reduced. When the concentration of narcotic drugs to a certain extent, the patient can restore spontaneous breathing, awareness will be sober, this time the anesthesiologist will pull out the tracheal tube, continue to give the patient mask oxygen, and remove the oral secretions.
General anesthesia refers to the process of inhalation, intravenous, intramuscular or rectal infusion into the body, the central nervous system is inhibited, resulting in the disappearance of the patient consciousness and the whole body without pain sensation process. This type of anesthesia is often saying "sleepy", characterized by the disappearance of patient consciousness, muscle relaxation, experience no pain. The most commonly used method of general anesthesia is tracheal intubation general anesthesia, is characterized by intravenous anesthetic or inhalation anesthetic to produce general anesthesia, intraoperative need for tracheal intubation, mechanical assisted breathing.
Tracheal intubation general anesthesia process. This procedure includes anesthesia induction, anesthesia maintenance and anesthesia awakening. The so-called anesthesia induction, is to make people from sleep to sleep state. Patients into the operating room, the first open by the nurses intravenous access (that is, acupuncture infusion), anesthesia doctors connected ECG, blood pressure, blood oxygen saturation monitoring, mask oxygen. Then the anesthesiologist can begin anesthesia induction. Anesthesiologists will give patients intravenous anesthesia or inhalation of anesthetic gas, the patient after 3 to 5 minutes after treatment will disappear, from the sober into the sleep state. In the general state of anesthesia, because there is no consciousness, the whole body muscle relaxation, the patient lost the power of breathing, spontaneous breathing will usually disappear, so the patient into the general anesthesia state, the anesthesiologist will be tracheal intubation, Tube device with the aid of an endotracheal tube through the patient's mouth or nasal cavity into the patient's trachea, the other end of the tracheal tube connected to the anesthesia machine, through the anesthesia machine through the tracheal tube to the patient delivery of oxygen to help patients breathe.
