Li Qinghua couldn't understand what Ren Haitao said.

He knew about Cedarsineh Medical Center, a huge private hospital that few people knew about in the country, but which had an unusual status in the United States.

Isn't it good for the interventional cardiologists at Cedars-Sinai Medical Center to stay in the United States and earn a lot of dollars? Why do you want to come to Huaxia to be a clinical doctor? And let Ren Haitao say that he didn't dig it up with a lot of money, but rushed to it himself...... It's simply unimaginable.

The two chatted, and the little doctor in the lead coat finished filming and packed up the film and went to the radiology department to wash the film.

Ten minutes later, the little doctor rushed back with a chest X-ray from the bedside.

Ren Haitao stood in front of the reader and watched it for a long time, then took a photo and sent out the image data.

"Old Ren, how do you feel?" asked Li Qinghua again.

However, it was determined that it was negative pressure pulmonary edema, and the diagnosis was relatively clear. Because it is rare, I must ask Mr. Wu to help me take a look. ”

Ren Haitao said while watching the film, "Qinghua, the small tidal volume and high-frequency breathing you gave after a short laryngospasm may be the cause of negative pressure pulmonary edema. ”

Li Qinghua frowned, but did not refute Ren Haitao.

"Laryngeal edema is a manifestation of upper airway obstruction. Positive end-expiratory pressure should be changed, and the patient's symptoms will be relieved quickly. Ren Haitao didn't notice the change in Li Qinghua's expression, and continued, "The small tidal volume and high frequency ventilator-assisted mode you gave, the patient increased his breathing effort, produced intrathoracic negative pressure, and further aggravated pulmonary edema. ”

"......" Li Qinghua sighed deeply.

Ren Haitao doesn't seem to know about relatives near and far, but he starts from business and doesn't consider his feelings.

Alas, but it can't be said that he is wrong.

This man...... It's really stupid to do. From the previous Haitao's position in the second hospital of the Medical University was more embarrassing, Director Xu couldn't do without him, and he had to be wary of him, but Ren Haitao didn't seem to be aware of it, and worked and studied stupidly every day.

Li Qinghua reminded him of these things many times, but when Ren Haitao listened to it with his left ear, his right ear popped out, and he didn't take these important interpersonal interactions to heart at all.

"Wait a minute, Mr. Wu won't reply for 5 minutes, I'll call. Ren Haitao looked at the film on the reader, his eyes did not blink. The light of the reader is reflected on the face, so focused.

In less than 5 minutes, Ren Haitao's mobile phone rang.

He glanced at his phone, a look of excitement on his face.

"Qinghua, I'll answer the phone. Ren Haitao answered the phone as he walked out, "Teacher Wu, hello, I'm sorry for your trouble." ”

"Patient's ......" He walked farther and farther, his voice was intermittent, and Li Qinghua did not follow, but looked at the patient's ECG monitoring in a daze.

Although the heart rate is sinus, it beats about 140 times per minute, which makes Li Qinghua feel a little irritable.

To be honest, Ren Haitao's "outspokenness" made him very uncomfortable. But the two have been in an old relationship for many years, and he knows Ren Haitao's personality.

This is also one of the reasons why Ren Haitao's goods were delayed in the second year of medical college. There's no one behind it, and that broken mouth always tells the truth, and wants you to tell the truth...... Now, of course, is needed.

Is there any mistake in his own handling? Li Qinghua has been pondering this matter for a long time.

At that time, when the ventilator data was changed, there should be no problem, but why did the patient develop negative pressure pulmonary edema.

"Qinghua, the PEEP of the ventilator is given to 7...... No, give 8. Soon, Ren Haitao came back and said confidently.

"So tall?" Li Qinghua was stunned for a moment.

If the positive pressure at the end of the expiratory breath is given to 8, can the patient still catch his breath, Lao Ren is sure that he is not joking? If he didn't know Ren Haitao's personality, Li Qinghua would have cursed a long time ago.

"Well, an increase in positive end-expiratory pressure can reduce the excessive alveolar surface tension due to insufficient alveolar surfactant, and improve the imbalance of ventilation and blood flow. Ren Haitao said, "Dimi, give 10mg." Furosemide, give 20 mg. Observe the changes in the condition and estimate that you will be well within 1-2 hours. ”

Li Qinghua didn't have any ideas, what Ren Haitao said and how to do it.

He had heard of negative pressure pulmonary edema, but there was no research at all. Even if you tell him the diagnosis, you still have to find information about what treatment plan you want to propose. However, the data is too different from the actual situation, and there is no clinical experience to rely on, and if a treatment error, the patient may have to have a tracheotomy, and even sudden death may occur.

According to Ren Haitao's confident words, and let the legendary Teacher Wu help take a look, it doesn't matter if you try it first.

10 mg of hormone and 20 mg of furosemide did not cause death in a 19-year-old woman. What worries Li Qinghua the most is that Ren Haitao said that the positive pressure at the end of expiratory breath is raised to 8 cm of water column, can the patient stand such a high pressure?

After some psychological struggle, Li Qinghua had no choice but to do what Ren Haitao said.

Adjust the ventilator parameters, administer medication, and shake the head of the bed by 30°.

Worried, he sat on the side of the patient's bed and observed the changes in his condition. After about 30 minutes, the oxygen saturation displayed on the monitor begins to gradually increase.

It worked! Li Qinghua was overjoyed. He carefully observed for another 20 minutes, and the patient's oxygen saturation was indeed rising, rather than rising transiently, and then falling off a cliff.

Li Qinghua listened to the breath sounds of the patient's lungs with a stethoscope, and the rales were significantly reduced and the breath sounds increased.

Li Qinghua knew the use of furosemide to increase urination and improve cardiopulmonary function, but he didn't dare to use it casually at that time.

Without knowing why, any change could lead to a worse outcome, and Li Qinghua was still very cautious.

However, the improvement of PEEP on ventilators does not seem to have side effects, but brings a series of positive changes.

After giving the medicine twice intermittently, Ren Haitao's eyes lit up, staring at the patient and the values on the machine. As the patient's blood oxygen saturation continued to rise slowly, Li Qinghua's heart gradually let go.

It was almost 12 midnight.

After a day of hard work, Li Qinghua was tired and wanted to find a place to sleep. But Ren Haitao was still staring at the patient's vital signs energetically, without blinking his eyes, and he was embarrassed to go.

Until half past one in the second half of the night, the ventilator was stopped for oxygen and 3 L/min/L was used for nasal cannula 25% ethanol humidification inhalation.

The ventilator was stopped, and Li Qinghua knew that it was okay. Being able to go offline so quickly was something he didn't expect. Before looking for Lao Ren, Li Qinghua was even ready for tracheotomy.

Fortunately, Lao Ren can understand negative pressure pulmonary edema,

Fortunately, I didn't hesitate to ask Lao Ren directly to help,

Fortunately......

Li Qinghua thought in his heart.
