Zhang Feng and his brothers crossed the small asphalt road and entered the town health center. The town health center is also a few rows of low tiled houses. As soon as Zhang Feng and the others walked into the night shift doctor's office, Chang Huiguo, who was bored, immediately called Nurse Guo, who was on night duty, to play cards.

The four of them entered the doctor's duty room and faced each other in pairs and began to play. Chang Huiguo and Nurse Guo teamed up. against Zhang Feng and Chang Huiyong. Chang Huiguo is in her twenties, and Nurse Guo is a young woman in her twenties. Zhang Feng and Chang Huiyong are both sixteen or seventeen years old. So the age difference between the four is not much, so they had a lot of fun.

The four of them were having a good time when they suddenly heard someone knocking on the door outside, and someone called for Dr. Chang.

Nurse Guo said, "Listen to the voice is Xiaolu." At this time, the Standing Council had already opened the door.

Zhang Feng saw that it was Xiao Lu standing outside the door, another nurse who could work the night shift in the town health center. There were also old men of sixty or seventy years old standing next to him.

I only heard Xiao Lu say: "Doctor Chang, my father can't pee again, you can quickly think of a way for him." ”

"Yes, Doctor Chang, I'm suffocating." The old man said, holding his little belly in both hands. The old man's little belly bulged like a woman who was three or four months pregnant. Zhang Feng understood at a glance that this old man was a patient with acute urinary retention caused by prostatic hyperplasia. It is also a common emergency patient in urology. It is also very simple to deal with, and that is to catheter catheterization.

But the key is that the difficulty of inserting the urethral catheter from the hyperplasia prostate is not generally high, which requires a high level of skill on the part of the doctor.

Sure enough, Zhang Dafeng heard Chang Huiguo say: "Xiaolu, it's not that I don't want to deal with it, I really can't insert it into the urinary catheter, bladder puncture is that your grandfather has diabetes and is prone to infection." The second is that your grandfather's blood pressure is still high. I really don't dare to pierce him! ”

"What then? My parents went to my aunt's house in the city today and will be back tomorrow. Xiao Lu hurriedly said, "Not to mention whether I can find the car at night, even if I find it, it will be 2 hours before I send my grandfather to a relatively nearby city, and my grandfather will not be able to hold out at that time, right?" ”

"Yes, I'm about to suffocate to death, Doctor Chang, please save me." The old man was busy talking. "I really can't cure it." Chang Huiguo was helpless.

"I'll give it a try. My brother-in-law is the director of surgery of the Second Municipal Hospital, and I often play with him during my vacations, and I have also inserted urinary catheters for many patients. Zhang Feng really couldn't stand it on the side, Zhang Feng didn't know how many such patients he had dealt with in his previous life. So the technology is steely.

"You, can you?" It was Nurse Guo who was suspicious. "I believe him, let Zhang Feng try."

"yes, let this new doctor give it a try." The old man also said on the side. He was really suffocated, and that's how he rushed to the doctor. Zhang Feng knew that Xiao Lu believed in him, mainly because of the trust he had cultivated by playing cards with Zhang Feng in the past year.

Xiao Lu only graduated from the health school last year. It can be seen that Chang Huiguo likes Xiaolu, but unfortunately the falling flowers are affectionate, and the flowing water is unintentional. Xiao Lu is a little hiding. So playing cards together, she always played against Erchang with Zhang Feng and his gang. And Zhang Feng has loved to play cards since he was a child, and he often plays cards with ordinary big ones in the village, so his playing skills are very high.

Seeing that the patient agreed to let Zhang Feng try, Chang Huiguo opened the door of the surgical treatment room. A crowd of people poured into the treatment room. Xiao Lu helped her grandfather to lie on the treatment bed, and Zhang Feng closed the door of the treatment room after letting Chang Huiyong go out. Because it is often brave that one person is an irrelevant person.

Zhang Feng walked to the treatment cabinet, he took a set of disposable masks and hats and put them on. Zhang Feng took the guard tweezers from the instrument tank with his left hand, and he took a pair of pliers from the instrument tank with his right hand. At this time, Chang Huiguo had already asked the old man to get his pants and underwear ready.

Zhang Feng used the tweezers in his left hand to clip a iodophor cotton ball from the iodophor cylinder, and then used the pliers in his right hand to take it, and he disinfected the old man's urinary catheterization area from the inside out, and so on three times.

Chang Huiguo and Nurse Guo glanced at each other, and they were so skilled in aseptic operation and disinfection operation.

After the poison was eliminated, Zhang Feng put the tweezers and pliers in his hand into the pool for washing.

Dr. Zhang picked out a pair of No. 7 sterile rubber gloves from the treatment cabinet, tore open the package, pinched the two gloves with his left thumb and forefinger, and folded the wrists back to lift the two gloves.

Zhang Dafeng inserted the glove in his right hand with his right hand, and then used his right hand to put it on first, avoiding the outside of the right hand glove from touching the wrist of the left hand glove and folding the inside of the wrist when wearing, and finally using the left hand to help the right hand put it on, which also avoided contamination of the outside of the left hand glove.

Chang Huiguo, Nurse Guo and Xiao Lu were dumbfounded, it was really a textbook-like operation.

Xiao Lu has more confidence in Zhang Feng.

"Urine tube 14." Zhang Feng turned his head and walked to the treatment bed after giving a command. Xiao Lu walked up to Zhang Feng with a No. 14 urinary catheter and opened the outer package.

Zhang Feng took out the urine tube from the packaging bag and connected it to the urine bag handed by Nurse Guo, and then took a piece of iodine cotton ball that Chang Huiguo had clamped with pliers, and wiped it on the urine tube. One is to disinfect again, and the other is to play a role in lubrication when plugged in.

The preparations before catheterization have been completed, Zhang Feng held the old man's penis with his left hand, and the urethral catheter in his right hand was inserted through the external urethral opening on the glans. The old man just said "ah" and stopped talking, and the taste of the foreign body inserting into the urethra can be imagined. But the old man also knew that he was inserting a urinary catheter, so he had to endure it.

The catheter went smoothly at first, but it couldn't be inserted after about 10 cm of it. Zhang Feng knew that it was the urethral tube that encountered the hyperplasia of the prostate.

Zhang Feng tried to insert the urinary catheter in different directions a few times to determine the position of the prostate.

Zhang Feng gently lifted the old man's penis at an angle of about 40 degrees obliquely above his lower abdomen with his left hand, and inserted the urethral catheter with a little force with his right hand, and immediately felt a sense of frustration.

Zhang Feng knew that this was a urethral tube inserted into the bladder. He took the 20 ml syringe with saline from Xiao Lu and injected it into the balloon of the urethral catheter to complete the sterile catheterization.

Sure enough, the old man groaned in comfort, and saw that the yellow urine filled the 1000 ml urine bag in less than ten seconds.

Xiao Lu cheered beside him: "I knew that Zhang Feng, you would definitely do it." ”.

Zhang Feng laughed and said, "Okay, let's put so much urine first, and it is easy to be unstable when I urinate more than 1000 ml at a time." As he spoke, Zhang Feng closed the urinary tube.

Zhang Feng then said to Xiao Lu: "Put it every five minutes, after this time the urine is finished, the urethral catheter will be taken care of normally, and the urinary catheter will be kept overnight, and you will pull it out for him tomorrow morning." Xiao Lu answered, and Zhang Feng cleaned up and went back to the doctor's office.

About twenty minutes later, everyone returned to the office, and the old man kept thanking Zhang Feng, who said a few polite words.

Xiao Lu said: "Zhang Feng, my father wants to ask you if this disease can be cured radically, and how to cure it?"

"Actually, my parents went to the city today to inquire about this matter." Xiao Lu finally said.

Dr. Zhang replied, "Everyone knows that this disease is called prostatic hyperplasia, but in fact, men over 50 years old will suffer from this disease, but the severity is different. ”

"If you want to cure this disease, you have to have surgery. There are two surgical methods: the first is the traditional method, which is to cut the patient's abdominal wall and bladder after anesthesia and remove the hypertrophic prostate. ”

"The disadvantage of this method is that it is not only painful for the patient during the operation. Even after the operation, the patient is in pain. This is because the patient's prostate gland will form a depression after it is removed. After this depression, it is necessary to use a urethral balloon injected with saline to compress and stop the bleeding, and the patient will always have the urge to urinate but cannot urinate at all. It's definitely not a good taste. ”

"What about the second bell surgery?" Xiao Lu asked on the side.

Dr. Zhang replied, "The second surgical method is prostate resection, which is to insert a metal tube as thick as a urethra through the external urethral opening like a urethral catheter, and when entering the hyperplasia prostate, the prostate is removed with an electric knife at the front end of the metal tube to stop bleeding. There is also no need to compress the hemostasis with a saline-infused urethral balloon after surgery. ”

"Then you can just do the surgery this way." Nurse Guo said on the side.

Zhang Feng smiled and said: "The first bell surgery method can be done in Jiucheng County People's Hospital and municipal hospitals, and even I have done many tables." Everyone had just seen Zhang Feng's technique of inserting a urinary catheter, so no one thought that Zhang Feng was bragging.

Zhang Feng continued: "The second surgical method is not available in the city or city, and if you want to do it, it is estimated that you will have to do it in the provincial capital or the capital.

Xiao Lu let out an 'ah'.

After a while, Xiao Lu and her grandfather left. The four of them were disturbed by this incident and lost their interest in playing. So Zhang Feng and Chang Huiyong quit and went back to school to sleep.
