Xue Dongqing also looked nervous, and quickly took out a stethoscope from his pocket and put it on the old man's chest.

"Heart rate of 120 to 130 beats per minute, murmurs in the mitral valve, wheezing in the lungs, and crackles......" Xue Dongqing said to himself.

"Doctor, you must save my dad." A middle-aged woman grabbed Xue Dongqing's sleeve and begged bitterly, she should be the old man's daughter.

"Hmm." Xue Dongqing responded, but he didn't have much confidence in his heart, usually in the hospital, when he encountered this situation, he could immediately give oxygen first, and then conduct a series of examinations such as blood sample analysis, X examination, and cardiac color ultrasound, so that after a full set, the cause could be figured out.

But now he doesn't have any instruments, and he is just an ordinary dermatology resident, and he has long forgotten about that little thing in internal medicine, at this time Xue Dongqing regretted it a little, he really shouldn't have done it.

At this moment, a voice suddenly came from his ear, "Doctor Xue, I think this patient is very likely to have sudden acute left heart failure!" ”

Xue Dongqing looked up and saw that it was none other than the student of Donghai Medical College, who couldn't help but look pale and said impatiently: "Why do you say that?" Although the patient had symptoms of acute left-sided heart failure, acute pneumonia or sudden asthma could not be ruled out......"

At this time, the middle-aged woman interjected: "Doctor, my dad has a history of asthma before, but he hasn't had an attack for seven or eight years, and he has high blood pressure and diabetes, what kind of emergency do you think he will have this time?" ”

"How do I know? I'm not a charlatan, just by looking with my eyes and listening with my ears, I can make a mess of diagnosis, don't bother me. After listening to the middle-aged woman's words, Xue Dongqing's mood became even more irritable, this large number of chronic medical histories, all of them are not good to serve, if you are not careful, if you kill someone, then your reputation will be over.

"Don't worry, I'll listen to the heart and lungs." Out of instinct, Xue Dongqing became more cautious.

"Doctor Xue, please believe me, this patient is likely to have a sudden acute left heart failure, and please treat the symptoms immediately." The nagging of the medical student rang out again.

Xue Dongqing was a little angry, raised his eyes, and said unceremoniously: "You medical student who has not yet graduated, what are you commanding blindly?" Did you know that clinical medicine is all about prescribing the right medicine? You didn't do anything, just say that this patient has a sudden acute left heart failure, what basis do you have? Is your eye X-ray not successful? Get out of the way and don't get in the way of my medical appointment. ”

Hearing Xue Dongqing's words, Lu Tianyu was stunned, he never thought that his kindness would be regarded as a donkey's liver and lungs.

He opened his mouth to say something, but as soon as his mouth opened, he stopped there, and said, "Doctor Xue, congratulations, you guessed it, my eyes really have X-ray function." If you really say that, you must be scolded as a psychopath, although you are telling the truth.

Lu Tianyu was very depressed, he just started the X-ray function of the "pea camera", and found that the old man's heart shadow was significantly enlarged, the pulmonary vascular texture increased, the edges were blurred, the hilar density increased, the structure was unclear, and the cuff sign appeared, all of which were very typical X-ray manifestations of left heart failure, but unfortunately he couldn't say it.

At this time, the passenger next to him pointed to Lu Tianyu, and there was also a lot of discussion.

"He's a medical student who hasn't graduated yet, and he doesn't understand anything, so he jumps out and talks nonsense, and he really doesn't know what to think."

"At a glance, I know that this kid's academic performance is not very good, I hope he must not graduate, otherwise, he will come out and kill people!"

……

Listening to everyone's accusations, watching the old man's breathing become more and more rapid, Lu Tianyu was anxious, at this moment, he felt helpless for the first time, as a college student who had not yet walked out of the school, his strength was too thin and weak.

There was a sudden commotion from the crowd of onlookers, and then a middle-aged man wearing glasses squeezed in, carrying a small medicine box behind him, "Conductor, my name is Lu Dong, I am a cardiologist, I work in Donghai People's Hospital, I heard that a patient on the train suddenly fainted, I came to take a look." ”

"Lu Dong?!" Hearing this name, Lu Tianyu suddenly felt a glimmer of hope.

Lu Dong, director of the Department of Cardiology of Donghai People's Hospital, enjoys a high reputation at home and abroad. When he was in his junior year of internal medicine, he also gave two lectures in person, and his witty manners and detailed case studies left a deep impression on Lu Tianyu, and he didn't expect to meet him here again today.

There were also a few people around who knew about Lu Dong's reputation, and they all said: "Director Lu is here, that's great, the patient is saved." ”

Xue Dongqing also seemed to know Lu Dong's name, so he quickly got up and said respectfully: "Director Lu, hello, I'm ......"

Lu Dong raised his hand to interrupt his self-introduction, "Let's talk about it later, it's important to save people now." As he spoke, he crouched down, pulled out his stethoscope, and listened carefully.

After a while, he stood up, stretched out his glasses, and said in a deep voice: "Conductor, this patient has a sudden acute left heart failure, his condition is very serious, and he must be sent to the hospital immediately. ”

The conductor nodded and said, "Director Lu, don't worry, I have already notified the next station, they have already contacted the local hospital, and the ambulance is waiting at the station, and it is estimated that we will be able to reach the next station in twenty minutes." ”

"That's good!" As he spoke, Lu Dong opened the medicine box he was carrying, and took out a disposable syringe from it, as well as a bag of glucose water and a small bottle of injections.

"Classmate, have you ever learned intravenous injection? Do you know what this injection is? Turning his head to Lu Tianyu, Lu Dong suddenly raised his voice and asked.

"Intravenous? Learned. This injection should be 0.4mg of cedilan. Lu Tianyu hurriedly replied.

"Good! You give this patient an intravenous injection of cediran right away, pay attention to the speed. Lu Dong commanded cleanly.

"Huh? Oh, right away! Lu Tianyu was a little flattered, and he didn't know how the famous Director Lu could trust him so much, but now was not the time to think about this.

Lu Tianyu skillfully unpacked the package, diluted cedilan with glucose water, took a deep breath, calmed his mood, found the old man's veins, and slowly pierced it, the originally noisy carriage suddenly quieted down, and everyone's eyes fell on him.

"Don't rush, push slowly, don't be in a hurry." Lu Tianyu kept admonishing himself in his heart, while his eyes were fixed on the old man's breathing. At the same time, Lu Dong on the side also stretched out his finger and put it on the old man's wrist, silently observing the patient's pulse.

At this moment, they are engaged in a race of life and death with death!
