Even if the leg was amputated on the spot, Yang Ping didn't want to do it hastily.

Clear the debris next to it and place a waterproof sheet under the thigh.

Xiao Wu's steps are clear and his hand speed is very fast, as Yang Ping's assistant, he wants to be qualified.

The sterile pack is opened, sterilized, and then lined with a sterile sheet and a towel.

"Syringe, 10% lidocaine, saline, diluted one to one!" Xiao Wu has already handed it over.

There is no anesthesiologist, only local anesthesia.

How high level of local anesthesia skills do you need to do for amputation under local anesthesia? Dr. Lu from the emergency department sweated.

Local anesthesia is generally used for minor surgeries, small debridement sutures, small mass excision, etc. The dosage is too small to achieve the purpose; Too large and prone to narcotic poisoning. There was once a hospital where a ganglion cyst on the back of the hand was cut, and the local anesthetic was overdosed, and the patient was poisoned by anesthetics on the spot and died in the outpatient operating room.

Therefore, a slightly larger operation, even if it is a larger debridement and suture, will not use local anesthesia, the risk is high, and the effect is not good.

Now Yang Ping wants to use local anesthesia to amputate his leg? Everyone was amazed.

Local anesthesia is not simple, but it is also a technical job. Ordinary, a few injections around the surgical area are also local anesthesia; Precisely, selective innervation nerve block is also a local anesthetic.

The latter is called a nerve block, which is actually a more advanced form of local anesthesia. If we use the former analogy to use artillery to indiscriminately attack the enemy's position, then the latter is to use precision-guided missiles to eliminate the enemy's strongholds at specific points.

To master nerve block anesthesia, it is necessary to be very familiar with anatomy, with the innervation of various areas, and with the movement of nerves.

Yang Ping will now have a block of the right femoral nerve and sciatic nerve.

Anesthesiologists often use color ultrasound to locate this kind of block, and Yang Ping now completes it with his bare hands.

Dr. Lu waited and waited and opened his eyes - amputation under local anesthesia.

According to the walking of the femoral nerve and the sciafemoral nerve, Yang Ping first blocked the femoral nerve - in the upper thigh, starting from the skin, anesthetized layer by layer, carefully pierced, when it reached the nerve sheath, the electric shock immediately opened.

"Do you feel like you're electrocuted?"

"Yes!" The patient gritted his teeth and said.

The drug is then injected into the sheath of the nerve.

In the same way, the sciafemoral nerve is blocked, and the skin sensation of the entire lower extremity comes mainly from the branches of these two nerves.

Just as the propagation of electrical currents by wires is cut off, nerve impulses are successfully cut off by anesthetics.

The effect was very good, and after a while, the patient's right lower limb was no longer felt, and Yang Ping began to operate.

The knife cuts out a beautiful tongue-shaped flap, the skin, subcutaneous, deep fascia, muscles, blood vessels are ligated, the nerve is cut at a high level, exposing the femur, and in the middle and lower thirds, the wire saw saws off the femur, and slightly rounded the broken end of the femur.

The tongue-shaped flap is then cut out of the contralateral muscle, deep fascia, subcutaneous, and skin.

The bleeding points were ligated one by one, and the operation area was clean.

The amputation is done in less than five minutes and possibly less. Wrap the broken end with a sterile sheet, and continue to process the rest on the car.

Several first responders started, the patient was immediately carried onto the ambulance on a stretcher, nasal cannula oxygen, continuous ECG monitoring, and the nurse quickly connected various pipes and lines, and then sorted it out.

The stretcher was placed in the middle, with Yang Ping Xiaowu sitting on one side and Dr. Lu and the nurse sitting on the other side.

The car started and rushed towards Sanbo Hospital. In order to save time, the driver chooses the fastest and smoothest road in navigation.

Lidocaine is local anesthetic and can last from one to three hours. The anesthesia is still working, and the patient does not feel pain. Dr. Lu thought that if he mastered Yang Ping's superb nerve block, in the future, during the first aid process, there would be no need to inject morphine for the pain caused by trauma, and the patient would be directly and highly selectively sent to the hospital without pain.

In the car, within a limited space. Yang Ping and Xiao Wu carefully rinsed the severed end of the amputation. Disinfect the sheet again, and suture the muscles, fascia, and skin. Amputation is over. It's also a matter of minutes.

"Doctor, will I survive?" The patient's voice was already very weak, his face and lips were pale, and his eyes were closed, and he struggled to open them a little.

The liquid has been opened to the fastest, and the three channels are infused at the same time, colloidal fluid and crystalloid fluid, which are injected into the body.

Yang Ping held his hand tightly, cold.

"Yes! Absolutely! ”

The patient gasped for breath and tried to speak, but could not speak several times.

"Don't talk anymore, it'll be fine, hold on!" Yang Ping took his hand and put a little more force to show encouragement.

The patient still squeezed out a few words: "Help--I --, the child--read--junior high school--pitiful--"

A few words that are intermittent, and I can't squeeze out words anymore.

This kind of ambulance is very advanced, but it is still an ambulance, and it can only provide the most basic life support such as rehydration.

For a short time, fluid can maintain volume, but blood transfusions are eventually needed to replenish red blood cells and maintain oxygen transport. Blood transfusions can only be done in hospitals.

The heart rate has risen to 120 beats per minute, the blood pressure has dropped to 80/40mmHg, and the blood oxygen is barely maintained at 90% by oxygen inhalation.

I don't know if the swelling spleen capsule is broken, if it does, it will definitely die. It can only be a matter of luck, and sometimes, I have to admit that there is such a thing as luck.

Dr. Lu can no longer do ultrasound, and there is also a risk of squeezing the ultrasound probe. Even if you see a rupture, you can't do anything for the time being.

"Hurry up!"

Yang Ping said to the driver in front of him that he was holding the patient's hand, his fingers had been clasped in the radial artery, and the pulse was weak, and he felt that it would dissipate at any time.

"It's already the fastest!" The driver shouted, but the accelerator pedal under his feet was still deeper.

The nurse changed another bag of liquid, and Dr. Lui was anxious and sweaty.

The ambulance horn sounded rapidly, the driver shuttled through the traffic, and some cars in front actively avoided and gave way, but more cars ignored it. The driver is a retired car soldier with good skills, he calmly plays the steering wheel and constantly overtakes.

The biggest uncertainty in urban traffic is traffic jams.

Everyone prayed in their hearts, don't get stuck in traffic, don't, don't!

The patient was already delirious, shouting loudly, and only his eyelids moved.

The ambulance got on the viaduct, and suddenly, the car in front braked, slowed down, and slowly stopped.

The ambulance followed the car in front of it, slowed down and stopped, because the distance between the cars was well maintained, the ambulance stopped smoothly, and none of the patients caused too many bumps.

"What's going on?" Xiao Wu asked.

The driver shook his head: "I'll go down and have a look." ”

A long dragon immediately formed behind it, and when you look ahead, it is also a long dragon.

The driver pulled the handbrake, pushed the car door, got out of the car before and after checking, and then walked more than ten meters forward to inquire about the situation.

He came back and said, "I heard that a truck broke down in front of me and was stuck in traffic!" ”

No way! Everyone scolded.

At this time, there is no way to get stuck in traffic, there are all cars in the front and back, left and right, and there are stoppers in the convoy, which are jammed to death, and they can't advance or retreat.

Yang Ping's heart was like ashes, and the pulse in his hand only had a faint breath left, like a little candle in the wind, which would be extinguished at any time.

The fire of life, sometimes tenacious, sometimes extremely fragile, will be extinguished at any moment.

Dr. Lu opened the back door of the ambulance, put his hands on the pergola, and looked forward, but there was no end to the long queue, and when he looked back, it was still a long winding dragon.

He walked back and forth behind the car, his right fist slamming into his left palm, anxious.

Minutes and seconds passed.

The patient's consciousness was completely blurred, and he stopped moving his eyelids.

The heart rate is getting faster and faster, and the pulse is fleeting.

After looking at it a few times, the car did not move, and Dr. Lu raised his head and shouted heartbreakingly: "Help, the people in the car are waiting for help!" ”

Helicopters, even if they are called helicopters now, are too late, and not everyone has the opportunity to use helicopters. There are two helicopters in the hospital, one is under maintenance, and the other has been called in by a high-end insurance company to pick up patients.

The shrill horns and flashing lights of the ambulance, as well as the screams of doctors, alarmed the nearby owners who got out of the car to breathe. A big brother wearing sunglasses moved over in the narrow gap between cars and asked, "What's the situation?" ”

"The people in the car are waiting for help, and they are dying!" Dr. Lui was helpless and wiped his sweat with his sleeve.

Yang Ping and Xiao Wu were in the car, Xiao Wu stared at the ECG monitoring, and Yang Ping kept holding the patient's hand.

The eldest brother touched his head, took off his sunglasses, glanced inside, and then looked at Che Long.

Tear open the throat of the Northeast dialect:

"Hurry, hurry! Come and help, help, 100,000 urgent! ”
