Sixteen times repeatedly, the black bear did not dare to dodge, did not dare to move, and did not even dare to do the instinctive grinning action. Seeing that it was honest, the sand and gravel turned around indifferently.

Because he was seriously injured and couldn't make a neck back movement, he looked stiff and a little weird and funny.

"Teacher Wu, it's okay. ”

It's really rough, much rougher than himself, Wu Mian thought to himself.

However, Wu Mian's affection for the sand and gravel increased greatly.

The B-ultrasound machine itself has a mobile power supply, Wu Mian turned on the machine, waited for more than ten seconds to start the machine, found the gallbladder area under the xiphoid process of the right upper abdomen, and pressed it gently.

"Roar~"

"Smack~"

As the black bear roared, the gravel's palm slapped once more on its snout.

It is neither light nor severe, and brings enough painful stimulation without causing substantial harm.

Like an aggrieved kitten, the black bear clicked its little eyes, wanting to express its humility and obedience. But just as its body was about to move, it slapped its short kiss again.

The black bear is not without intelligence, and it quickly discovers that as long as it maintains a position and does not roar, it will not be beaten.

Seeing it lying on the ground honestly, Wu Mian shaved off the short bristles in the gallbladder area of his right upper abdomen, applied couplant, and pressed the B-ultrasound probe.

Although it hurt, the black bear remained motionless. In the constant beating, it has already figured out the pattern.

A strong echoic mass may be seen in the gallbladder, followed by a clear acoustic shadow. Because the black bear was lying honestly, no signs of a strong echo mass moving with the body position were observed.

"Diagnose gallstones, prepare for surgery. Wu Mian said, "Lateral decubitus position, high epidural anesthesia." ”

Gravel didn't ask whether it was left or right, it was obvious that he had some understanding of emergency first aid, and directly twisted the black bear's body to the left.

"Mr. Wu, the vertebral body of the black bear ......"

"It's about the same as humans, a little different, but not much. Wu Mian said, "I'll do the puncture, you just give the medicine." I told you about the concentration and dosage of the drug before. ”

Ren Haitao nodded and began to dispense medicine.

Wu Mian's hand rested on the black bear's back spine and gently groped. This is the vital part, the black bear feels scared, but it also has to face the existence that makes it even more afraid, so even if the vital part is held in the hands of others, it still lies honestly and does not dare to move.

The infrascapular angles on both sides were connected to the thoracic 7 spinous processes, and Wu Mian touched a vertebral body downwards and began to disinfect and puncture.

Ren Haitao completely forgot about the threat of the black bear, and he watched Wu Mian's every move with full attention.

The bottle of Flying Immortal-style albuterol in the past brought Ren Haitao's memory so deeply, in his memory, every action of Mr. Wu was not superfluous.

The spinous processes of the middle and lower segments of the thoracic vertebrae are shingle-shaped, with narrow gaps, making puncture difficult. Wu Mian did not try the direct entry method, but directly used the side entry method to puncture.

After 6 minutes of local anesthetic injection into the epidural space, dysesthesia may occur in the innervated areas of the skin in the upper and lower segments of the puncture site, 2 and 3 segments respectively. Wu Mian gently pricked the black bear's skin with a thin needle, and he was a little distressed at this time.

The sand and gravel are too coercive to the black bear, causing the black bear to feel pain and dare not move, and he has no way to communicate with this product.

It's too much, that's the truth. However, in the face of the existence at the top of the food chain, Wu Mian has no reason to blame the sand.

After 20 minutes, the block can be expanded to the expected extent and the anesthesia is complete.

Wu Mian washed his hands with clean water and wore sterile gloves.

Although the level of sterility here is not up to par, it is the only way. You can't take a black bear to the hospital, because if you do, the impact will be huge.

Wu Mian still believes that these kings of the forest and the wild have strong resistance and immunity, and it is no problem to give antibiotics for a period of time after surgery.

Routine disinfectant towels. Take an oblique incision under the right costal margin, about 7 cm long. Layer-by-layer incision of the skin, subcutaneous tissue, anterior rectus abdominis sheath, blunt separation of the rectus abdominis muscle, incision of the posterior rectus abdominis sheath, and parietal peritoneum.

Even if Wu Mian performed surgery alone, he was still quick and simple, Ren Haitao was dumbfounded, and asked, "Teacher Wu, the anatomy of a black bear is the same as that of a human body?"

"It's different, some of the differences are still obvious. ”

"That ......"

"Do you know what it means to be at ease?" Wu Mian said, having already done a good job of peritoneal protection, opening the peritoneum and entering the abdominal cavity.

The black bear is honest, perhaps out of fear of the sand, or because it is particularly well anesthetized and has no pain at all, or it may know that these humans are treating itself, so it is quite honest.

"Human anatomy can also be abnormal, and not all of them look the same as the anatomy atlas. Wu Mian said, "Don't worry about the specific details, just grasp the big principles." As much blunt separation as possible, less bleeding and less injury is sufficient. ”

While chatting with Ren Haitao, Wu Mian probed the abdominal cavity of the black bear.

Abdominal exploration showed that there was no obvious ascites and exudate in the abdominal cavity of the black bear. The gallbladder is widely adhered to the surrounding tissues, pus is seen on the surface, and the gallbladder is tense.

It is estimated that the black bear has a fever, and the inflammation is so severe, it must be inevitable that there will be an inflammatory reaction. However, Wu Mian has not studied the basal body temperature of black bears, and it is not important whether they have fever or not, and they can be given antibiotics for a period of time after surgery.

Wu Mian then made a purse suture at the bottom of the black bear's gallbladder and cut open the gallbladder wall to relieve pressure. Along the bottom and both sides of the gallbladder, 1 cm away from the liver bed, the serous membranes on both sides of the gallbladder are incised, and the gallbladder is gradually separated from the gallbladder bed from the bottom of the gallbladder to the gallbladder neck.

The movements were delicate and gentle, Ren Haitao looked at the surgery twice, and then at the black bear, feeling that this natural beast did not seem to be as terrible as the legend, and gradually relieved his heart.

Besides, he has been numbed, Ren Haitao doesn't believe that this product can fight against large doses of anesthetic drugs to chase himself.

Mr. Wu's surgery was really good, which Ren Haitao already knew. But what was different in front of me was that it was not a human who underwent the operation, but a black bear.

Even if he operated on Xiong, Mr. Wu still did not hesitate or hesitate. The hand speed is not very fast, and it is not dazzling, but it is so steady and step by step, and in less than 6 minutes, the gallbladder has been free from the gallbladder bed.

"Mr. Wu, have you operated on a black bear before?" Ren Haitao asked with some confusion.

The surgeries are all familiar, and seeing Mr. Wu's movements is light and skillful, it definitely doesn't look like the first time to operate on a bear.

"No, I had an operation on Panda Liangliang before. However, there is still a difference in the anatomy between giant pandas and black bears. ”

"Then you ......"

"Didn't you say it, it's easy. Anatomical anomalies that are not beyond my skill. ”
