However, intravenous injection of some narcotic drugs will cause some pain and other discomfort. General anesthesia is a safe and effective anesthesia method, which is very suitable for critically ill patients, especially those with unstable hemodynamics. Intraspinal patients actually have certain advantages for elderly patients with lung diseases, which should be selected according to the different operations of patients and the personal technical level of anesthesiologists.
Semi-anesthesia refers to spinal anesthesia, which is a method of injecting local anesthetic into epidural space or subarachnoid space to block the anterior and posterior roots of spinal nerve and produce anesthesia. Patients under general anesthesia are unconscious during the whole operation, while patients under semi-anesthesia are awake during the whole operation, but they are under anesthesia to a certain extent.
Which is safer, general anesthesia or semi-anesthesia? In fact, both general anesthesia and semi-anesthesia are very safe. Now worldwide, the anesthesia mortality rate can be reduced to11/300,000, which is similar in China. You may say that this is the mortality rate, but some doctors will say that this is the incidence of other complications. Tens of millions of cases of anesthesia are performed every year in the world, and the probability of overall complications is also very low.
The complications of semi-anesthesia and general anesthesia have their own characteristics. Take semi-anesthesia as an example, patients may have nerve damage, and some people may have a piece of skin on their feet that will be numb or particularly sensitive after semi-anesthesia. General anesthesia will also have a certain incidence of complications, compared with semi-anesthesia, there will be more unique complications.
Because many times during general anesthesia, tracheal intubation is to put the catheter into the airway with the help of laryngoscope, some patients' teeth are already loose, and there may be a risk of falling off during intubation. When communicating with patients, the risks will be clearly explained and most patients can understand.
Some patients may lose their teeth after abdominal surgery, and doctors will explain them well, especially the risk of loose teeth. At this time, they will make a special assessment and talk about other risks. You may wonder if you will never wake up after general anesthesia, basically not. At present, general anesthesia drugs are very safe and the incidence of complications is very low. These two drugs are very safe, and patients can make appropriate choices according to their own needs or according to their doctor's advice.
