Start as an Emergency Physician

Zhou Yuan had already found the needle insertion point, and pierced Lin Hai's skin at a twenty-five degree angle, and it was not until the needle was two-thirds of the way that Zhou Yuan felt the needle enter the blood vessel.

The average person's needle only needs to enter one-third to one-half, and the thickness of the subcutaneous fat layer of Linhai can be seen...

In fact, if the blood vessels in the back of the hand are not clear, you can inject or infuse the fingers, wrists or arms of the player.

Among them, the blood vessels of the fingers are the best to identify, most people are easy to find the blood vessels of the thumb and index finger or middle finger, and a few patients are easy to find the blood vessels of the ring finger and little finger, depending on the situation.

Zhou Yuan did not choose to perform finger sticks because finger sticks are not easy to tighten the skin and fix the needle handle, and the patient is more painful.

It is estimated that Lin Hai should wake up in a while, if he finds that he has a needle on his finger, the visual shock effect is definitely more terrifying than the needle on the back of his hand.

As for the other option, arm injection and infusion, some blood vessels in the arm of patients are more convex and exposed, and some are the opposite, while Lin Hai's own fat is mainly concentrated in the arm, which makes it more difficult to find blood vessels from the arm.

Anyway, intravenous injection is still a technical job, you need to rely on your own feelings, the angle of needle insertion depends on the depth of the blood vessel to change moderately, the smaller the needle angle is, the faster the needle is inserted, and the less pain the patient will have. The so-called painless needle insertion is a small angle of rapid needle insertion.

After the needle enters the blood vessel, Zhou Yuan enters the needle in the direction of the blood vessel, and then inserts the needle parallel in its direction after seeing the blood return.

Zhou Yuan didn't like to tie it to the medial joint of the wrist, the lateral joint he chose last.

The blood vessels in the medial joint are thick but slippery. In addition, even if the blood vessel is successfully pierced from the medial joint, there is a high probability that the needle will be injected afterwards, and the needle can slide out of the blood vessel with a slight movement, which is especially unsuitable for the elderly and children.

Some novices like to choose the medial joint needle insertion, the blood vessel will improve their success rate of needle insertion, but the patient needs to pay extra attention not to move, in general, it is convenient for the doctor and painful for the patient.

Zhou Yuan has a master-level intravenous injection, and there is nothing he can't solve in terms of intravenous injection, so Lin Hai's injection is not difficult for him, after finding the blood vessel from the back of his hand, he pushes the needle into the blood vessel from the distal end to the proximal end to protect the blood vessel, and finally completes an injection.

Zhou Yuan did not leave, but waited until he was fully hydrated, gave another intravenous insulin loading dose, and then began to administer a small dose of insulin intravenously.

In the case of adequate rehydration, the rate of blood glucose drop is 5 mmol/h, and after the initial rapid rehydration, the rate of rehydration and insulin addition need to be reduced.

If the osmotic pressure drops suddenly, it will affect the tension of blood vessels, lead to impaired perfusion function of important organs such as the brain, cause cerebral edema, etc., and may even aggravate the dysfunction of microcirculation. ‘

"Now you can stop the insulin drip. Once the blood glucose drops below 3 mmol/L, home insulin is pumped intravenously again at a maintenance dose of 0.. 05~0.1u/(kgh). Zhou Yuan reminded.

Zhang Ling nodded: "Understood." "

Lin Hai's parents were already waiting anxiously, and when they saw that Zhou Yuan was finally free, they hurriedly ran over.

"Doctor, what the hell is my child! This child is usually healthy, not sick!"

Lin Hai's mother is a middle-aged woman with kind eyebrows, which is very much in line with the image of a loving mother.

Zhou Yuan was silent for a moment and looked at Lin Hai.

Before falling unconscious, I drank two large bottles of Coke, if it was packed according to 1.25 liters, that is, 2.5 liters, the average Coke contained about 10 grams of sugar per 100 ml, and 2.5 liters was half a catty of sugar.

Is it possible for a normal person to ingest half a pound of sugar in a short period of time?

Moreover, people with more than 100 kilograms have blood sugar as high as 130, and the examination results show that Lin Hai has serious liver damage, abnormal blood sugar, and dyslipidemia.

"The blood sugar is too high. "

When Zhou Yuan was silent, a crisp voice came from outside.

Sun Meng, who was in charge of the night shift, walked into the ward and greeted Zhou Yuan with a smile, she was a little surprised that Zhou Yuan hadn't left yet, it had been more than an hour since the day shift got off work, and she also came to check the ward before she happened to meet Zhou Yuan.

Zhou Yuan nodded: "When I meet a patient with blood sugar 130, I can't go." "

Sun Meng's smile froze suddenly.

"One hundred and thirty?!"

She listened to Zhou Yuan's handling just now and knew that it was because her blood sugar was too high, but one hundred and thirty was too terrifying!

Ordinary people have blood sugar of thirty or forty, and it is good to be able to walk into the hospital, but there are really people with blood sugar of one hundred and three?!

Sun Meng once met a patient who rechecked his blood sugar after the infusion, and found that there was 80, and everyone in the emergency department was scared to death, and later found that the nurse was pumping the blood vessels that had just finished delivering glucose.

In other words, the blood that has been specially transfused with glucose is only 80, and Lin Hai has reached 130, which is not the category of normal people at all...

Sometimes, the human body is extremely miraculous, and the cancer that had been worsening suddenly disappears, and the medical level judges that it will not live for three months and finally skip 20 years.

And now, up to one hundred and thirty blood sugar.

What is this concept?

Our kidneys have millions of nephrons, each nephron has a glomeruli, responsible for filtering glucose, protein and other substances in the original urine, when the blood sugar is too high, it will increase the glomerular filtration pressure, and even forcibly destroy the glomerular filtration function, resulting in the destruction of nephrons, and eventually damage the entire kidney.

A blood sugar of 130 must have damaged the kidneys.

In addition, high blood sugar levels can also have a serious effect on the nerves, especially in the lower limbs, such as wounds that are difficult to heal and feel numb.

In addition, high blood sugar can cause distortion of the retina, which can affect the image on top of the image, and even lead to blindness. Moreover, it increases the burden on blood vessels, increases the chance of thrombosis formation, and so on...

Being able to survive, although it is not a medical miracle, Lin Hai can definitely be regarded as a blessing.

Sun Meng, who originally wanted to say that it was handed over to her, held back her words again.

Although she has the ability to deal with high blood sugar, she really can't accept the super high blood sugar of one hundred and thirty, no wonder Zhou Yuan wants to stay specially, except for Zhou Yuan, who is a master of art, I am afraid that only an old fritter in the medical world like He Jianyi dares to treat...

It is possible to damage the cardiovascular and cerebrovascular vessels, cause blood vessel blockage, and put their lives in danger.
