Chapter 915
The essence of snow blindness is the acute aseptic inflammatory reaction caused by ultraviolet rays burning the cornea.

Not to mention Ningyuan, a place like Ningyuan where it doesn't snow much in winter.Even in the northern region, many people do not have the habit of "wearing sunglasses when going out after heavy snowfall".

Generally speaking, snow blindness is more common in plateau areas-the snow here does not melt all year round, and the ultraviolet rays in the air are much stronger than those in plain areas.Walking on the snow for a long time, there is a risk of cornea burns by the ultraviolet rays reflected by the snow.

Although Ningyuan is only snowing now, the sky is covered with lead clouds.But Dr. Cao Yanhua has been a little restless since he sneezed twice - he decided to make preparations.

As if to prove that Dr. Cao Yanhua's worries were not wrong, suddenly people's voices became noisy a little distance away.When Dr. Cao looked through the gap in the crowd and saw the person lying on the ground, his pupils shrank suddenly.

problem occurs.

Taking off the pink down jacket on his body, Cao Yanhua rushed out holding the medical kit.The place where the crowd gathered was about seven or eighty meters away from him, and he himself fell three times in a row on the way to rush over.The nurse sister who was closest to him didn't even get to the place where he fell, and helped Dr. Cao up from the ground. He struggled to stand up by himself, and then continued to run forward.

Stumbling and running out of breath, Dr. Cao Yanhua squeezed through the crowd with all his strength, and then rushed to the side of the man who fell on the ground.

This is a master worker who is responsible for installing the board room.He also wore a somewhat worn-out bright yellow hard hat on his head.The helmet was firmly buckled on his head, and according to Dr. Cao Yanhua's first judgment, the worker in front of him didn't seem to have any other obvious injuries.

"Give way!" Cao Yanhua squatted beside the master worker and began to conduct a quick inspection.And the nurses finally arrived at the scene, and they took the initiative to ask the medical history in the early stage, "What's the matter with this person?"

"Before Lao Feng went to work this morning, he said that he had some leg pain." The staff member who was closest to the worker hurriedly explained the situation, "When Lao Feng was cutting boards, he suddenly sat on the ground with his buttocks. His face paled. Bai, he couldn't speak. I saw that something was wrong with him, and thought it was because the air in the room was not good, so I quickly dragged him out."

"Then he..." The nurse wanted to ask a few more questions, but Cao Yanhua suddenly began to take off the coat of the worker's master, and then began to perform chest compressions. While pressing, he shouted: "Heart arrest, go get it AED! Call 120!"

There is no fixed location for AEDs on the train station square.The nearest AED is located at the security check entrance at the gate of the check-in hall.

Without saying a word, the nurse turned around and ran towards the ticket office 300 meters away.But Cao Yanhua didn't have the time to pay attention to these at all - the patient under his palm was not in a good condition.

No one in cardiac arrest ever gets better, but he seemed to be doing exceptionally well.There was an ominous purple-black color on his lips, and his pupils looked dilated.

Performing full chest compressions is a very physically demanding job.Although the feet were still numb from the cold just now, after the two sets of compressions, Dr. Cao Yanhua's head began to have sweat dripping down.

Thirty compressions, two breaths, thirty more compressions... Chest compressions outside the hospital are like a hellish marathon with no end in sight.Not only is there no end, but there can be no slack in the slightest—as long as you slow down a little, this life will definitely be gone.

As the doctor in charge of the Chest Pain Center, Cao Yanhua has seen countless patients with ventricular fibrillation and sudden arrest.But in the fourth hospital, he at least has a solid mind and knows what measures should be used to treat and stabilize patients.But now it is in the square in front of the Ningyuan Railway Station, and the medicines stored in the medical point have not yet been counted—he is not even sure if there is dopamine in it.

Fortunately, when the sixth set of compressions was carried out, another doctor and a nurse came from the station.They took over the chest compressions and replaced Cao Yanhua, who was already on the verge of hypoxia.

Halfway through the ninth set of chest compressions, Dr. Cao Yanhua, who had recovered a little bit, completed the patient's tracheal intubation during the compressions, installed a balloon and started compressions.

At the same time as the intubation was completed, the nurse who rushed to the ticket gate to get the AED also rushed back.Everyone worked together to remove the clothes of this master worker surnamed Feng completely, and then stuck the electrode pads on.

"Begin the electric shock, please don't touch the patient." After Dr. Cao Yanhua covered the patient with his thick clothes, the AED completed the electrocardiogram analysis, and then began the electric shock cardioversion.After seeing the patient's body trembling slightly, Cao Yanhua was the first to kneel down again and continued to perform chest compressions.

The four medical staff performed chest compressions on the front and rear feet for almost 20 minutes. After the AED called out "heart rate returned to normal", the four people sat down on the ground.

Everyone is sweating profusely.

Dr. Cao Yanhua sat on the ground, observed after removing the balloon, and was slightly relieved after confirming that the patient was breathing spontaneously.

The medical team stationed at the hotel has rushed over with an ambulance.They arrived at the scene even faster than 120-the 120 ambulance that was assigned a task still doesn't know where it is struggling.

"Now there is sinus rhythm, and there is also spontaneous breathing." Dr. Cao Yanhua took the time to explain the situation to the doctors who came to pick him up, and then he said in a low voice, "But the consciousness has not recovered. After a while, the pupils are not quite right."

When pressing the balloon, Dr. Cao Yanhua saw that the pupils of the patient's eyes were not in the right condition—the pupils on both sides were unequal in size, and the pupils on the right side narrowed like pinpoints.

In other words, this is most likely not a cardiovascular accident, but a case of cardiac arrest caused by a cerebrovascular accident.A cerebral hemorrhage forces pressure on the pons or brainstem, causing cardiac arrest.

"Understood. Send me to the hospital immediately." The doctor who came to take over was also an old colleague who had worked in the emergency department for many years, and he immediately understood what Dr. Cao Yanhua meant.Looking at the thin clothes on Cao Yanhua's body and his sweaty face, he warned, "Keep warm, and be careful not to catch a cold." Then he pushed the cart and left the square in front of the station.

"Thank you, doctor." The worker who dragged Lao Feng out of the construction site just bowed to Cao Yanhua gratefully, and then wiped the tears from the corners of his eyes with his hand, "Old Feng's family has an 80-year-old The old mother is here, and there are two children who are going to school below... If something happens to him, I don't know how to tell them about it..."

Cao Yanhua tried his best to force a smile, "Now that the patient is sent to the hospital, we will definitely do our best..." But he knew very well that such a patient... might not survive at all.

Patients with brain hemorrhages that cause compression of the pons or brainstem have little chance of surviving.
