"Disposable syringe, draw heparin NS, 2.5ml." Qin Feng shouted.

Zhao Qi hastily took a 20ml disposable syringe, extracted 2.5ml of heparin NS, and handed it to Qin Feng. Qin Feng took the syringe, and directly advanced the needle in the condyle for bone puncture, and sucked the bone marrow into the needle tube.

Qin Feng stopped after aspiration of 20ml of bone marrow with a 7.5ml needle.

It's not that Qin Feng doesn't want to pump more, but it's related to bone marrow transplantation. In bone marrow transplantation, the amount of marrow drawn for each needle penetration should not exceed 10ml, and the ratio between bone marrow blood and NS is 3:1, that is, It is said that 2.5ml of heparin NS can only extract 7.5ml of bone marrow fluid.

Director Li took the syringe handed over by Qin Feng, and used a 16-gauge needle and a 9-gauge needle respectively to filter the extracted bone marrow. At the same time, Zhao Qi handed over the prepared sterilized bag and stored the filtered bone marrow in the sterilized bag.

It's just that when Zhao Qi was taking this step, Qin Feng directly stopped him.

"It can't be put in like this directly, and additional processing is required." Qin Feng said.

"Additional processing is required?" Both Zhao Qi and Director Li were stunned.

When did bone marrow extraction require an extra process in addition to bagging during bone marrow transplantation?How to deal with it?

Two questions lingered in the minds of the two, and it was a severe test for their majors.

"An additional treatment can effectively reduce the graft-versus-host reaction and reduce the chance of postoperative complications to a certain extent," Qin Feng explained.

Zhao Qi and Director Li were still a little confused.

Qin Feng looked at the expressions of the two, shook his head, and moved the bone marrow in the needle tube to the blood cell separator for additional processing of the bone marrow cells.

Soon, the bone marrow and blood cells were separated directly after being centrifuged by the blood separator. Qin Feng took out the bone marrow and sent the blood cells back to Director Jin's body.

"Brother Qin, isn't this step redundant?" Zhao Qi asked.

Qin Feng took out a new needle, "Not redundant, the patient's medical records show that Director Jin's blood type is A, but the blood type of Director Jin's daughter is AB, although it is said that type A blood can be delivered to type AB blood, but heparin The fusion of NS with bone marrow and thick blood will make the blood cells have antibodies, which will be repulsive to Director Jin's daughter to a certain extent."

"Antibodies and rejection, as well as the immune system, I think you all know it, so I won't explain it much."

Director Li's eyes gradually widened. He actually didn't consider what Qin Feng said. He only considered how to separate bone marrow and transplant it.

But in fact, once the concentration of antibody blood in the patient's body is greater than 250/[-] of the normal blood, then in the case of the patient's immune system has been destroyed, there is no way to resist the attack of the antibody, and the red blood cells can only be destroyed , leading to more serious conditions.

"You follow the method I just did to filter the bone marrow blood, and establish two venous channels at the same time, one is used for infusion, and the ratio of the surgical field is three times that of the extraction volume, and the other is used to transport autologous blood to maintain the blood volume and blood pressure of the donor. "Qin Feng reminded.

Zhao Qi and Director Li nodded, and the two quickly formed a division of labor.

Director Li is in charge of intraoperative blood pressure maintenance, and Zhao Qi is in charge of venous access and filtration.

Watching the movements of the two, Qin Feng continued to concentrate on extracting the bone marrow.

It takes about 7.5ml to extract, but only [-]ml each time, which is why [-] disposable needles are stored. This process is extremely cumbersome and repetitive.

Unlike the usual operations, Qin Feng's operation was performed very slowly.

For transplant surgery, although the patient's condition is urgent, it is not critical, as long as the transplant can be successful.

At the same time, Qin Feng's slow extraction speed also means that it can reduce the discomfort of the donor. There is also a rule for extracting bone marrow in the hospital, that is, it takes at least 10 minutes to extract every [-] ml of bone marrow blood. If the extraction is too fast at one time, it is easy. Make the donor unable to get off the operating table.

After almost two hours, Qin Feng's extraction work was completed, and he let out a sigh of relief.

Glancing at Zhao Qi, Zhao Qi also filtered the last bone marrow blood, twisted his waist, and let out a long breath.

Extracting bone marrow is no easier than performing a surgical operation.

The whole extraction process is to keep bowing your head, extracting, extracting, and repeating.

"Damn it, Xiao Qin really knows how to pump bone marrow?" The dean showed a surprised expression, and then a look of joy hung on his face.

The more things Qin Feng will have, the easier it will be for Taoshi No. [-] Hospital to be rated as the top three.

The title of top three is the goal that all municipal hospitals strive for.

"Hmph, who knows if it was done randomly, and the donor won't be able to get up when the time comes, I'll see what he will do." Yin Zuowu snorted coldly.

A trace of worry also flashed in the dean's eyes. This is also a common problem for doctors who pump bone marrow for the first time.

The next moment, Director Jin was carried down and sent to the ward to recover.

Qin Feng took Zhao Qi and Director Li directly to the operating room and went to the transplant cabin.

"Hmph, let me just take a look, a boy with no hair at all, maybe what is extracted is not bone marrow blood at all." Yin Zuowu's face was full of displeasure. In his opinion, Qin Feng was just a sensationalist.

In the end, what Qin Feng left behind still needs to be dealt with by himself.

The dean glanced at Yin Zuowu, and said softly: "Director Yin, Doctor Qin Feng is not the brat you mentioned, he is now the deputy chief physician of our Second Hospital."

"Just him? Deputy chief physician? Your hospital is really worthless!" Yin Zuowu shook his head, not giving any face to the director of the Second Hospital.

The director of the medical department was about to say something when he was stopped by the dean.

"Director Yin, how about we make a bet? If Dr. Qin Feng in our hospital performs the operation perfectly, we will give you a place for advanced training in your department." The dean said with no joy or anger on his face.

Yin Zuowu looked at the dean of the Second Academy, "Okay, I promise you, but if he doesn't finish it, I will go up and finish it, and the cost of the throwing knife will be doubled."

"it is good."

After completing the verbal agreement, the two went to the transplant cabin to continue to observe the operation.

At this time, Qin Feng and others have also arrived at the transplant cabin.

Qin Feng glanced at Director Jin's daughter in the cabin. The patient's face was obviously swollen, and his hands and feet were also swollen to a certain extent. His face was extremely pale, even much paler than those of the shock patients.

This is also the common point of chemotherapy patients. Long-term continuous chemotherapy will cause adverse reactions in patients, such as nausea, vomiting, etc., but in order to survive, these must be experienced.

After being tortured by adverse reactions, the patient's state is like this.

"Has the hematopoietic stem cell suspension arrived?" the doctor in charge asked.

"Well, it's here." Qin Feng asked Zhong Aiqing to pass the suspension to the doctor in charge.

The transfusion of bone marrow is different from other surgeries. It does not require surgery. It just needs to be stared at by a person like an infusion, and the stem cell suspension is injected into the patient's body by intravenous infusion.
