Up to now, the hospital has performed caesarean section for parturient and basically implemented combined spinal-epidural anesthesia. This kind of anesthesia is also commonly known as semi-anesthesia. The anesthesiologist will insert an epidural catheter between the third and fourth thoracic vertebrae of the parturient and slowly inject and release the anesthetic through the catheter.
This semi-anesthesia has many advantages. During caesarean section, the parturient's abdomen is under anesthesia, so she can feel no pain, but her mind can always stay awake. If the mother has any physical discomfort, she can tell the surgeon at the first time to ensure the safety of the operation. More importantly, the anesthetic dosage of this anesthesia method will not be passed on to the fetus, thus eliminating the problem of fetal respiratory disorder.
Another advantage of this kind of spinal anesthesia is that the anesthesia tube can be kept after caesarean section, and the anesthetic can be released slowly with the postoperative analgesia pump, which can be maintained for 24 hours after operation, which can effectively alleviate the postoperative pain of parturient.
This kind of anesthesia also has some disadvantages, that is, it may cause adverse reactions of the ligament behind the parturient and cause temporary waist discomfort, but these discomfort symptoms will disappear after rest.
General anesthesia is easier to understand Anesthesiologists inject anesthetics into the maternal body by inhalation to inhibit the central nervous system, and the maternal mind will completely disappear. After the operation, the anesthesiologist will wake up the parturient.
Some pregnant women who have had abortion feel that it is ok to sleep with a needle of intravenous anesthesia when doing abortion. Why can't caesarean section anesthesia be so simple?
The biggest difference between caesarean section and induced abortion is to consider the fetus in the maternal stomach. The fetus does not breathe before birth, and the oxygen it needs is used by the baby after the mother inhales oxygen and passes through the placenta. Any improper anesthesia method or excessive anesthetic drugs may affect the exchange of oxygen and endanger the health of the fetus. Therefore, the choice of caesarean section anesthesia must consider the minimum impact on the fetus, and the use of spinal anesthesia is the result of comprehensive evaluation.
Now, only when the parturient is not suitable for semi-anesthesia, such as suffering from a certain disease, the hospital will take general anesthesia for caesarean section. The dosage of anesthesia in general anesthesia operation may affect the fetus, so it is necessary for doctors to monitor the newborn's breathing.
The third local anesthesia method, which belongs to unconventional practice, is rare. Local anesthesia, that is, local infiltration anesthesia, is the simplest and most direct anesthesia method. The effect of this anesthesia method is far less than that of general anesthesia and spinal anesthesia, and the pain caused to the parturient is also relatively strong. Only when there is fetal distress and the anesthesiologist is not on the scene, or when the fetal distress is serious and needs to be delivered as soon as possible, or when the parturient is complicated with difficult airway and spinal anesthesia contraindications, this anesthesia method will be used to complete caesarean section.
In the 1960s, Chinese medicine also tried to use acupuncture anesthesia to help parturient perform caesarean section, which was said to be successful and a medical documentary was filmed. But after all, there are problems with operability and reproducibility, and most pregnant women dare not try and cannot promote it. Now, they have disappeared.
