Chapter 306 Head down and feet up, lying on the left side

Du Annan's judgment was indeed correct. It was indeed this hemodialysis machine that caused He Rong's sudden change in condition tonight.

During the process of repeatedly adjusting the catheter, the nurse in the hemodialysis room continued to lose patience. In addition, during the last adjustment, she was always thinking about communicating with Du Annan about medication, so she did not tighten the interface of the catheter, which allowed the air to take advantage of it.

.

Fine air constantly entered He Rong's blood circulation through the gaps. Because the amount of air entering was so small, the machine did not even recognize the alarm.

The nurse in the hemodialysis room quickly stopped the blood pump, re-tightened the catheter interface, and directly reinfused the blood into the patient's body, pausing the dialysis treatment.

Du Annan and the night shift nurse prepared to put the patient in a left-lying position with his head down and his feet up.

Dr. An said at this time: "Air embolism occurs when fine air enters the right atrium through the veins, causing air atresia between the pulmonary artery orifice and the right ventricle, causing cyanosis and hypoxia."

"If the gap at the interface is not found and air continues to enter He Rong's body, once the pulmonary artery entrance is completely blocked, He Rong's death will happen in an instant..."

Thinking of such serious consequences, Dr. An suddenly felt frightened and did not dare to think about it any more.

"Fortunately, An Nan is familiar with the patient He Rong enough to determine that the problem lies in the dialysis, otherwise it would be too dangerous!"

However, although the problem was discovered, it was far from timely. In more than half an hour, a large amount of air entered He Rong's blood circulation, accumulated at the pulmonary artery opening, and continuously merged into a large air mass.

There is no blockage, but it is not far away from being blocked.

The thorny problem now is that the extracorporeal circulation has been suspended and the blood circulation in He Rong's body has become closed again. How to remove the air mass blocked in He Rong's heart?

He Rong's symptoms are already very obvious. If the air mass is not broken up in time, the symptoms of hypoxia and cyanosis cannot be relieved, and the danger to his life will still exist.

"Teacher nurse, please hold He Rong up so he doesn't fall off the bed. I'll raise the bed!"

While Dr. An was thinking, Du Annan had already cooperated with the nurse to put He Rong into position.

He Rong is a young man in his twenties. Although five years of dialysis treatment has made him much thinner than his peers, for two women, putting him in a specific position is still a problem.

A very laborious thing.

Du Annan trotted to the bed, sweating profusely, and quickly shook the handle to raise the bed.

He Rong's lying position at this time was very strange.

The head is low and the feet are high, lying on the left side.

A patient with dyspnea is almost standing upside down on the bed. In terms of comfort alone, this position must be extremely poor.

But when Dr. An saw this scene, not only did he not stop it, but he nodded in approval.

"Using body position and hemodynamics, trying to squeeze and break the air mass blocking the pulmonary artery in a closed environment..."

Dr. An was unable to directly participate in the rescue due to her special physical condition. Seeing Du Annan carry out the rescue so calmly and calmly, she breathed a sigh of relief and had time to take out her mobile phone to contact her colleagues in the emergency department.

Du Annan stared closely at He Rong on the hospital bed. The oxygen flow had been turned on to the maximum at this time. The sound of air flow was constantly coming from the humidification bottle. The monitor also started to alarm. Nothing seemed to be getting better.

.

"I have to believe in myself..."

Du Annan clenched his fists nervously, but kept calm inside. You can be nervous during the rescue process, but you must not panic. Clear thinking is the key to a successful rescue!

The conditions in the ward are limited, and all the physicians present have little rescue experience. Increasing the oxygen flow, changing the lying position, and using the anatomy and hemodynamics of the pulmonary artery to break up the air mass may be the best rescue plan.

.

Du Annan believes that as long as the large air masses can be squeezed and broken, and restored into fine air to enter the next round of blood circulation, then He Rong's body can slowly absorb these fine air, and the crisis will naturally be resolved.

After doing everything he could, Du Annan could only give hope to He Rong himself. As long as his 20-year-old heart is strong enough to squeeze and crush the air, everything will be fine!

After talking to the emergency department on the phone, Dr. An said with a serious face: "The doctors from the emergency department will be here soon. If it doesn't work, ventricular puncture will be necessary!"

Hearing that this method of rescue was to be used, everyone present had solemn expressions.

Ventricular puncture is a method of directly inserting a puncture needle into the heart through the surface of the body, and using external force to help the patient remove the air blocked in the pulmonary artery.

This is a first aid measure of last resort, and is rarely used even in emergency departments.

I hope He Rong will not come to this point...

Time passed by, and fortunately, He Rong's symptoms gradually improved.

The rapid breathing rate began to slowly recover, the oxygen level increased, and the frightened expression gradually calmed down.

Although the medical staff present could not see clearly what was going on inside his heart, it was inferred from the symptoms that the air should have been squeezed and broken into pieces and entered the ventricle along the blood flow. The blockage of the pulmonary artery had significantly improved!

"Well done An Nan!" Dr. An couldn't help but said to Du An Nan.

At this moment, Du Annan breathed a long sigh of relief, and quickly bent down to level the end of the bed, allowing He Rong to return to his normal position.

Air embolism is an emergency. When the cause is unknown, the patient's condition will take a turn for the worse. However, once the cause is eliminated and the channel at the pulmonary artery is released, the patient's condition will immediately improve.

Danger is in one moment, but peace is possible in the next moment.

He Rong's breathing became slower and slower, and his breathing gradually calmed down. After about ten minutes, he looked around blankly, as if he didn't understand why there was such a large group of people in white coats standing on his bed in the early morning.

forward.

"What's wrong? The man next door is rescuing me?" He Rong casually pulled off the oxygen mask on his face and said dazedly as if he was drunk.

The curtain between the hospital beds shook violently, and a dissatisfied groan came from the bed next door.

Du Annan explained helplessly: "You were the one who was rescued just now. You had an air embolism and suddenly lost consciousness. You are really uncomfortable. Why didn't you tell me earlier? You actually fainted right away!"

He Rong blinked, as if he couldn't believe it. He pointed to his nose and said, "Did I just faint?"

Du Annan nodded: "Yes, you just said you wanted to write a novel, and then you kept writing on your phone. Suddenly you fainted, and you didn't agree to what I said..."

Before Du Annan finished speaking, He Rong immediately let out a scream, which startled everyone present, thinking that something had happened to him again.

But then, He Rong nervously picked up his cell phone, checked it, and then collapsed on the hospital bed in despair, with a look of despair on his face.

"Damn it, I've coded two thousand words and haven't sent them out yet, so I won't have perfect attendance this month..."

Du Annan looked at He Rong blankly, obviously not understanding what the other party meant.
