  The heart rate of the newborn baby is slow and not breathing. Basically, there is only one reason, the airway is blocked. The blockage could be mucus, it could be meconium, it could be something else.

  Because the baby\'s heart rate dropped to the dangerous limit, the doctor had to perform neonatal CPR to keep the baby\'s heart beating. Next, choose an opportunity to solve the airway problem.

  The establishment of artificial airway with positive pressure ventilation, the use of laryngeal mask, etc., is best done on the basis of airway patency, otherwise, each ventilation may push the obstruction into the airway. Therefore, they are very careful when using the breathing bag. At first, Song Xuelin didn\'t even need to breathe in the air bag, he used his mouth to blow air. In fact, he was trying to inhale to see if he could **** out the contents of the baby\'s airway.

   Clearing the blockage in the mouth and nose, the obstetrician did it when he caught the baby for the first time. When Song Xuelin took over, he quickly checked, and there was indeed no blockage in the baby\'s mouth and nose. It shows that the situation is very helpless. The blockage is expected to be blocked in the deep part of the child\'s trachea and it is difficult to come out, causing the child\'s dangerous situation today.

   To put it bluntly, if you want to use a laryngeal mask for intubation, it is better to use tracheal intubation. If the tracheal intubation is successful, at least make sure that the tube is in the trachea. You can put a suction tube into the tracheal tube to connect the negative pressure suction device, and carefully suction to see if the blockage in the trachea can be sucked out.

  This is not a hospital site where there is no negative pressure suction device. Endotracheal intubation dedicated to the neonatology department will not be available for NUS ambulances and emergency departments. Neonatal intubation is technically difficult. The emergency doctor on duty in the tertiary hospital is not a professional pediatric hospital doctor, and has no technical ability to perform tracheal intubation on such a small child, so he can only send it back to the hospital to find a neonatologist.

   to ask what to do. It\'s right to try to get your baby\'s heartbeat back. CPR compressions are performed on the thorax, which in a way is equivalent to thrusting the trachea.

   It’s just that these rescue measures are not strong enough so far, and the doctor may need to gamble. The rigor of medicine allows doctors to choose mild measures first, and take further risks if the patient and child fail. Any invasive medical operation is a double-edged sword. There are good and bad. When it is good, it can save a life.

   In the face of gambling, the doctor must first calculate the previous measures to try to give the human body enough time to react. Song Xuelin raised his head and asked the time: "How many minutes have we been doing?"

   After receiving his question, Lin Hao and Li Qi\'an tried their best to recall and estimate, "Maybe seven or eight minutes—"

   "It\'s been four minutes since I\'ve been involved. Before, Dr. Song, you took the baby out for five minutes. The total estimated time is about nine minutes and ten seconds." Xie Wanying said.

   Lin Hao and Li Qi\'an sighed in their hearts when they heard every precise time point she spit out: It turns out that time flies so fast. Like who said, Xie Xie is no different from the old doctor, which makes them only look at it.

  Song Xuelin\'s slightly squinted brown eyes flashed a stream of light. He was the most comfortable partner with Dr. Xie. Dr. Xie could always live up to expectations at critical moments.

   "Doctor Song, let\'s change hands, I\'ll try it." Xie Wanying suggested.
