What is the story about human nature that you want to tell most?

One year, I received a critically ill patient transferred from other places. The patient's life experience is very poor. He grew up without a father and was raised by his mother. Children grow up and live up to expectations. He opened a small factory himself and didn't want it to explode. The child was burned all over. Go to the local hospital for treatment after the injury. My condition has been extremely unstable because of severe inhalation injury. The patient suffers from multiple organ failure, especially respiratory failure, and relies entirely on the ventilator to maintain breathing. Patients with extensive burns usually need to remove necrotic skin early and repair the wound with micro-skin transplantation. However, because the patient's condition is extremely critical and it is difficult to tolerate the operation, the operation has not been carried out. With the passage of time, the patient's necrotic skin began to appear serious infection, which led to the deterioration of the patient's condition step by step. With a glimmer of hope, my family contacted us. I personally brought an ambulance, gave the patient a ventilator and sent it to Jishuitan Hospital. The patient's heart stopped beating less than 30 minutes after entering our intensive care unit. After emergency rescue and resuscitation, the patient's heart finally recovered. Today, I am still scared when I think about it. If this happens in transit, with limited equipment on the ambulance, the patient may be hopeless. I sat in a chair in the intensive care unit and reviewed my treatment plan over and over again. Finally, I'm sure I have no choice. I silently took out a death certificate and filled in all the information of the patient, leaving only the blank of the time of death. When I put down the death certificate. Suddenly I heard the nurse shout: Dr. Ning, the patient's blood oxygen began to rise. I looked up and saw the numbers on the monitor rising slowly, but I was sure, 87, 90, 92. The patient's blood pressure began to stabilize and urine volume began to increase. The turning point I have been waiting for has arrived. At the infinite distance from death, the sickle of death has touched the patient's throat, but it finally grazed it. We won the bet. When the patient finally regained consciousness, he pulled out the tracheal intubation, declared himself out of danger and transferred to the general ward. Mother and son got together and wept bitterly. I quietly walked to an empty corner and wiped the tears from my eyes. Many people ask me: Do you regret being a doctor? No regrets! The road ahead is bumpy, with complaints, but no regrets.
