The anesthesiologist couldn't believe it, holding the blood gas analysis sheet in his hand.

The values that catch your eye are very dazzling!

[PH value: 7.38]

[Carbon dioxide partial pressure: 38mmHg]

[Partial pressure of oxygen: 38mmHg]

He looked at the light blue value on the monitor again, which symbolized the oxygen saturation of the blood!

[Oxygenation: 100!]

Suddenly!

The anesthesiologist chuckled in his heart!

If the patient's blood oxygen monitoring is fine, the partial pressure of oxygen in the blood gas analysis is significantly lower than normal!

There's only one possibility!

The blood is indeed venous!

After all, after the human body alternates between the two major circulations of the body and lungs, the oxygen content of the blood in the veins is far lower than that of arterial blood!

"But why is the blood drawn from her body so red?"

"It must be a mistake in the laboratory department!"

The anesthesiologist was reluctant and clung to what little hope he had.

However!

Liu Dongfang's next words completely dashed his hopes!

"Don't forget, what we did today is a radical cure for the tetralogy!"

"And one of them is to repair the defect of the ventricular septum!"

With Liu Dongfang's reminder, the anesthesiologist suddenly realized!

"Damn, I forgot about it!"

He had just ignored the patient's presence of a ventricular septal defect!

After all, because of the anatomy of the human body, the heart is divided into four parts, each of which is related to each other and has a clear division of labor!

However, once there is a defect, which affects the original direction of blood flow, it will form a reverse flow!

Linlin on the operating table, because of long-term reflux, formed pulmonary hypertension, which then changed the original color of venous blood!

This caused the anesthesiologist to conclude that the "arterial blood" was actually a vein!

At this time!

The anesthesiologist's expression is wonderful!

And the test sheet in his hand weighed like a thousand pounds, making him tremble.

"Now do you have anything else to say?"

Liu Dongfang hung his head and didn't raise his eyelids.

The seemingly calm words reveal a sense of indifference.

The anesthesiologist only felt trembling all over his body, and couldn't help but tremble.

"No more. ”

The anesthesiologist was like a defeated rooster, gradually lowering his head.

Then!

A loud bang rang out!

"Since it's gone, why don't you hurry up and come over to assist in the operation!"

Liu Dongfang raised his head, and the sharpness in his eyes flashed in his eyes, which was thrilling.

"Oh, oh!"

As soon as these words came out, the anesthesiologist dared to delay, and immediately acted according to Liu Dongfang's instructions as if he had been beaten with chicken blood.

"It's pretty much the same, otherwise ......"

Liu Dongfang snorted coldly, and the warning was self-evident.

At this time, the anesthesiologist, how can there be a trace of arrogance, to Liu Dongfang, it can really be said that he must obey his words!

"A little more narcotic!"

With the use of ECMO, Liu Dongfang gradually became bolder.

After all, with it by his side, Liu Dongfang is more handy when he starts surgery!

"The dose of propofol has reached 5ml/hour, the patient is under deep sedation, and the RASS score is -5 points!"

The anesthesiologist looked at the anesthetic in the pump tube and injected it into Linlin's body little by little.

After checking the pupil light reflex and body irritation, he gave truthful feedback to Liu Dongfang.

"Good!"

Liu Dongfang nodded, his eyes were like torches, radiating light.

"Ready for thoracotomy!"

"Yes!"

"The skin surface is cleaned and disinfected, and the median sternal incision is prepared!"

"Understood!"

The instrument nurse takes out the dressing and needle for later use.

And the most striking thing is the sternal saw that is quietly set aside.

The sharp jagged teeth looked cold and piercing under the reflection of the shadowless lamp.

This is an indispensable part of thoracotomy surgery!

With the supplies ready, Liu Dongfang nodded, and then turned his head to look at Duan Kailiang.

The latter's face was calm, but his eyes showed a hint of nervousness and unease.

After all, it's his daughter who is on the operating table!

"Director Liu, let's do it. ”

"I'm sure Linlin will survive this!"

After a long time, the uneasiness in Duan Kai's bright eyes was replaced by firmness.

He looked at Liu Dongfang, his expression full of trust.

"Yes!"

"Don't worry, with me, Linlin will be fine!"

Liu Dongfang said in a low voice.

Then!

The skin is gradually dried out as iodophor is disinfected under the towel.

Liu Dongfang took out the scalpel.

The crystal clear blade was tightly held in his hand.

Liu Dongfang's eyes narrowed slightly, and his black pupils showed incomparable firmness.

"Aspirator ready!"

After the words fell, Liu Dongfang slashed the skin on his chest with a knife.

What catches your eye is the bright red tissue under the skin.

Liu Dongfang held his breath and peeled off the thyroid muscle attached to the sternum and the surrounding connective tissue little by little.

Suddenly!

The sternal stalk is as translucent as it is white.

"Sternal saw!"

Liu Dongfang gave an order, and then there was a heavy chainsaw in his hand.

This chainsaw is different from a regular household chainsaw.

It's more sophisticated and smaller!

When you hold it in your hand, you can't even feel the vibration of the rotation.

Liu Dongfang adjusted the speed of change according to the direction under the xiphoid process of the sternum, and then stepped on the pedal.

Zizizizi!

A metallic grinding sound permeated the operating room.

"Pay attention to the patient's vital signs and changes in consciousness!"

Liu Dongfang glanced at the values on the monitor, and then prepared to cut the sternum!

Sting!

The serrations made contact with the sternum, and a burst of white mist floated in an instant!

Liu Dongfang lifted the saw body, and the foot guards were close to the back of the sternum!

As the pedal was pressed, the chainsaw slowly and orderly advanced towards the patient's head under Liu Dongfang's precise control!

This is a bottom-up sternal incision!

With an incision in view!

The crowd even saw through the cracks that the heart was beating behind the pleura!

They held their breath and didn't dare to make a sound!

After all, a sternal incision is a big deal!

Everyone was afraid that the slight wheezing sound would affect Liu Dongfang's operation!

At this time!

Liu Dongfang's upper body is like a sculpture, motionless!

The tense arm muscles, with the advancement of the chainsaw, do not dare to relax at all!

"Prepare heparin and establish cardiopulmonary bypass!"

As soon as the words fell, as the chainsaw stopped, a hole of nearly ten centimeters appeared in front of everyone.

Puff puff puff!

With exposure of the thymus, anterior mediastinum, and pericardium.

The heart under the transparent membrane is contracting and relaxing in an orderly manner!

"Good!"

The hearts of the people have risen to their throats.

Following Liu Dongfang's instructions, Duan Kailiang hurriedly activated the extracorporeal bypass mode of ECMO.

Seeing this, Liu Dongfang cautiously opened the pericardial cavity!

Immediately, a beating heart emerged!

"This?!"

An exclamation rang out!

Surprise in everyone's eyes!

Their eyes widened and they stared at the living heart without blinking!

"How so?!"

Duan Kailiang's emotions were a little out of control!

"Don't panic!"

A cold drink rang out.

Liu Dongfang frowned, looking at the heart in front of him, with a trace of worry between his eyebrows.

I saw Linlin's heart, occupying the entire chest!

It was even so hypertrophied that it pressed on the left lung tissue, and there were symptoms of adhesions!

This is a classic ventricular hypertrophy caused by tetralogy of Fallot!
