I Can See Health

At this moment, the patient's eyes suddenly opened and he fainted.

Everyone present felt tense in their hearts.

If the endotracheal tube is not inserted into the patient's trachea and connected to a ventilator within one minute, the patient's heart may soon stop beating due to lack of oxygen.

However, Lu Chen did not disappoint everyone. After a few quick strokes, the tracheal intubation was inserted from the mouth into the deep part of the patient's trachea.

When the two nurses saw this, they immediately came over and connected the ventilator.

Lu Chen also quickly adjusted the parameters of the ventilator.

Puff puff puff, the ventilator began to inflate the patient.

"Give pure oxygen first." Lu Chen said after wiping the sweat from his face.

Unconsciously, his back was soaked.

"Where are the patient's family members?"

Yin Xinhua asked the nurse on duty in a deep voice.

"I have contacted the family and am on my way here," said a nurse on duty.

"Report to the medical department immediately." Yin Xinhua said seriously, "At the same time, please ask the ICU and respiratory department for consultation."

"Okay, I'll make a call."

Fan Zhiping nodded and immediately walked towards the nurse's station.

On the line between life and death, without family members to accompany you, it is very easy for disputes to arise.

This type of patient is extremely special, and the medical department must be notified so that they can help deal with this problem.

…

Put on a ventilator.

The patient is still in a coma and breathing rapidly, but he is slightly better than before.

The blood oxygen saturation increased from the lowest 70% to 92%. No matter how much I adjust the parameters, my blood oxygen saturation cannot rise.

"If the blood oxygen saturation cannot go up, there must be something wrong!" Yin Xinhua said solemnly.

The blood oxygen saturation of normal people is 100%, and the blood oxygen saturation of patients with severe pneumonia will definitely drop.

But if you connect a ventilator and give pure oxygen, you can get better quickly. For example, this patient has maintained a blood oxygen saturation of 92%...

Lu Chen thought of a possibility, that is pulmonary embolism!

He reexamined the patient's electrocardiogram.

This time the electrocardiogram yielded unexpected results.

The electrocardiogram showed relatively typical symptoms of high pressure load on the right heart, with lead i deepening, q/q waves appearing in lead iii, and t waves also causing the condition.

Professional respiratory and cardiologist doctors will know that this may be pulmonary embolism as soon as they see this electrocardiogram.

When the pulmonary artery is blocked by an embolus, the pressure in the entire pulmonary artery will increase, which will in turn cause the right heart pressure to increase, which will be reflected on the electrocardiogram.

Yin Xinhua gave a bitter smile and said: "Junior brother, this should be a pulmonary embolism. We have won the first prize. But now we definitely dare not push it out for a pulmonary artery CTA to confirm the diagnosis. We can only wait. Let's first call the respiratory department and ICU doctors. We'll talk about it later. We'll be responsible for stabilizing the vital signs first."

The most important thing is that the patient’s family members haven’t come yet.

Any subsequent operations require the consent of the patient’s family.

Less than five minutes.

The respiratory doctor came.

The patient's medical history was re-analysed, but the patient was in a coma and it was difficult to ask about his condition now.

After seeing the patient, the consulting doctor of the respiratory department returned to the doctor's office and said to Yin Xinhua: "Judging from the patient's onset speed, performance and electrocardiogram, it is indeed consistent with the symptoms of pulmonary embolism. Shortness of breath, hypoxia, respiratory failure in the short term, and no pneumothorax was found. , If possible, you can tell at a glance by doing a pulmonary artery CTA. If it is not possible, you can also see some symptoms by doing a cardiac color Doppler ultrasound or an electrocardiogram, especially a cardiac color Doppler ultrasound. "

The respiratory consultant also agreed with Lu Chen and Yin Xinhua's views.

However, Lu Chen frowned and said, "Senior sister, I have a question."

Yin Xinhua glanced at Lu Chen and said, "Say."

"If the patient is considered to have pulmonary embolism, he does not have any high-risk factors for pulmonary embolism!"

According to the patient's previous medical history, he had no history of lower limb surgery injuries, no long-term bed rest, and no congenital factors, such as protein S/protein C deficiency or anticardiolipin syndrome.

Why did Duan Duan end up suffering from pulmonary embolism?

This question stunned Yin Xinhua and the respiratory doctor.

That seems to be the case!

If you only look at the symptoms, it does look a lot like pulmonary embolism.

But there are very few cases of pulmonary embolism directly without risk factors!

"There may be other unknown factors." The respiratory doctor frowned. "In any case, pulmonary embolism should be considered first."

The reasons are put aside for now, and the treatment is the main priority.

Lu Chen nodded. The first priority now is to solve the patient's cause.

The ICU doctor came soon.

After looking at the patient's condition, he basically agreed with the judgment of Yin Xinhua and the respiratory doctor.

However, it is impossible for the patient to undergo a CT scan in this situation, unless he is pushed on a ventilator. However, the patient’s vital signs are still fluctuating. If something goes wrong along the way, something big will happen!

"You may need thrombolysis!"

Everyone’s discussion results were consistent, but further examination with color Doppler ultrasound or CT scan was needed before thrombolytic drugs could be used.

If I make a mistake, I'm afraid I won't be able to eat and I'll have to walk around.

Although thrombolytic drugs can dissolve blood clots, they may cause cerebral hemorrhage within minutes, which would be troublesome.

"How about we go to the ICU first and take a closer look at the situation. Then we will use our own cardiac color ultrasound in the ICU to see if we can observe any signs of pulmonary embolism. If it is really a pulmonary embolism, we will consider thrombolysis. If there is If we find anything else, we’ll analyze it first.”

Doctor icu told Yin Xinhua.

What patients need most right now is a ventilator, but if the patient really has a large-scale pulmonary embolism, the ventilator will not be very effective. The reason is simple.

The working principle of the ventilator is to put oxygen into the patient's lungs and force it into the lungs.

But if the patient's pulmonary artery is blocked by an embolus and no blood flows, effective blood and oxygen exchange will not be possible!

Oxygen alone is not enough. Without blood flow, it cannot bring in oxygen and cannot remove carbon dioxide. The patient will still die due to hypoxia and carbon dioxide retention.

Yin Xinhua nodded and agreed with the ICU doctor's opinion, "If pulmonary embolism is diagnosed and the timing is right, and thrombolysis is used to dissolve the embolus and restore the patency of the pulmonary artery, there should still be a chance. After all, the patient is so young."

…

About half an hour later. UU reading www. uukanshu.net

The family members are finally here!

The medical department also came forward to communicate and provide explanations.

However, the patient's family refused to be transferred to the ICU.

The patient's family member is the patient's sister. The patient is not married yet and rents a house in Jinghua. The sister works here and her income is probably not high. The ICU is simply bad news for them.

But the existence of ICU has indeed turned many people's bad news into good luck. This is also what many people look forward to.

The patient was quickly placed in a separate room and equipped with various monitoring equipment.

My blood pressure is low, and I can barely maintain it at hg with the use of active drugs.
