Zhang Zhenyu, pressing for half an hour to save the elderly patient

Expert biography: Zhang Zhenyu, male, 42 years old, chief physician of the liver ICU of Tsinghua Changgeng Hospital in Beijing, associate professor and master tutor of the Clinical Medical College of Tsinghua University, member of the Critical Medicine and Organ Support Professional Committee of the Chinese Health Science and Technology Promotion Association, member of the Critical Care Professional Group of the Parenteral Enteral Nutrition Branch of the Chinese Medical Association; In 2020, he was awarded the title of "Advanced Individual in Beijing's Fight against the New Crown Pneumonia Epidemic" and the title of "Advanced Individual in the Fight against the New Crown Pneumonia Epidemic of the China Democratic League".

In February 2020, medical workers from all over the country rushed to Wuhan, and the epidemic in Beijing began to worsen. On the afternoon of the 15th, Zhang Zhenyu received an urgent task assigned to Beijing Tsinghua Changgeng Hospital under the Beijing Municipal Hospital Management Center, and immediately rushed to Beijing You'an Hospital, one of the designated hospitals for novel coronavirus pneumonia in Beijing, to provide support, and the next day defecated to enter the new crown intensive care ward.

In the isolation ward, Zhang Zhenyu is "reversing the time difference" almost every day - the doctors work 6 hours a day, 8 o'clock to 14 o'clock, 14 o'clock to 20 o'clock, 20 o'clock to 2 o'clock in the morning the next day, 2 o'clock to 8 o'clock, and the cycle repeats. "The biological clock is basically disordered every day." Zhang Zhenyu said: "We are most afraid of falling ill, and if we can't help but drag everyone down." "Every day before going to work, Zhang Zhenyu will generally leave more than an hour in advance, fasting food and water, leaving enough time for wearing protective clothing."

A shift from 8 a.m. to 2 p.m., the operations were stable, the data showed good, but just when the work was about to leave, the 91-year-old patient with coronary heart disease who had a coronary heart disease suddenly called the alarm, and the blood pressure dropped rapidly, followed by ventricular fibrillation, and the situation was critical. The nurse shouted in the ward: "Doctor, come quickly!" The patient's heart rate and blood pressure dropped dramatically!" The voice was all too familiar to Zhang Zhenyu, who had worked in the ICU for many years, and he threw away his work and strode toward the patient. Heart rate 25! Blood pressure 35/20 mm Hg! Immediately following the ECG shows that the heart rhythm is in a straight line! Without time to think, Zhang Zhenyu immediately rushed up to the outside of the heart to press, and issued various rescue instructions, the medical staff tacitly cooperated, and various first aid measures were quickly put in place. At such an advanced age, coupled with the physical condition damaged by the new crown pneumonia, it is necessary to use VA-ECMO for life support immediately, but the arterial pulse is completely absent, how to locate the vein for puncture? All eyes were focused on Zhang Zhenyu, who was struggling to press outside the heart, and the next standard press was the road to life step by step. Through effective cardiac compression, the comrades supported by Anzhen Hospital can sense the pulsation of the femoral artery, so that the puncture catheter can be successfully punctured... Finally, after half an hour of CPR, the patient regained an autonomous sinus rhythm and the vital signs stabilized. At this time, Zhang Zhenyu in the protective suit was already soaked, and he was supposed to work at two o'clock in the afternoon, because of physical exhaustion, coupled with the fact that the water meter had not entered for more than ten consecutive hours, there were serious symptoms of hypoglycemia, and his trembling hands could not hold the chopsticks well.

"The new coronavirus is a completely new virus, and people are not yet fully aware and understood of it. All doctors can do is do their best to support seriously ill patients and create miracles of life. Zhang Zhenyu said: "As doctors specializing in critical care medicine, we face patients who are on the verge of death every day, and they and their families put all their hopes on us." We will definitely persevere until the last moment and never give up on any patient. The patient is entrusted with his life, and I will do my best!" ▲(Nanziyu)
