Just now, when Xiao Lu was checking for penicillin in the house, the Mo family was also anxiously waiting, Mo Lao Er was even more restless, looking at the hut from time to time, until Yuan Fang pushed open the door and came out, Xiao Lu brought good news, and Mo Lao Er's hanging heart was a little lower.

In addition to the three brothers of the Mo family, Xin Moyuan, Nangong Wenjin, Mo Wenyue, and Mo Wenfang were also there, Yuan Fang nodded to everyone, and was about to enter the ward, Mo Wenyue ran to Yuan Fang's side and pulled Yuan Fang's sleeve and begged: "Uncle Yuan, you must save your mother." ”

Mo Wenfang pulled Yuan Fang's other sleeve and said with tears in her eyes: "Uncle Yuan, please save your mother." ”

Yuan Fang squatted down, hugged the two little girls and nodded, and said, "Wen Yue, Wen Fang, don't worry, Uncle Yuan is here, I won't let your mother have anything to do, good girl, you wait outside, I'll go and save your mother." Wen Yue and Wen Fang nodded obediently, walked to their father's side, and watched the doctors walk into the ward.

In the ward, Xin Huilan has improved, although the wound is still very painful, but she can't take care of it, she is very worried to look at Jiang Chengjia who is getting weaker and weaker on the bed next to her, Xin Huilan and Jiang Chengjia have joined the Mo family, Xin Huilan is everyone's best girl, Jiang Chengjia has a gentle personality and is kind, the relationship between the two is very good, just like sisters, now Jiang Chengjia's life is in danger, Xin Huilan blames herself, she always feels that she has been a good sister.

Yuan Fang walked into the ward, first looked at Xin Huilan's wound, and came to Jiang Chengjia's bedside with a few words of comfort. Jiang Chengjia had a high fever that did not go away, and now he has fallen into a coma, and his face is extremely ugly, and it seems that he has lost half his life. When the gauze was removed, the wound had suppurated, and the thick water had deteriorated much worse than in the morning.

Looking at Jiang Chengjia's physical state, he no longer hesitated, but the disinfectant water handed by Xiao Qi cleaned the wound, applied the hot and detoxifying ointment and re-bandaged it, and next, it was time to start injecting penicillin, and everyone present watched Yuan Fang's every move curiously, for fear of missing something.

Grabbing Jiang Chengjia's thin right hand, tying a tourniquet and patting the blood vessels on the back of his hand, Yuan Fang explained: "This can make the blood vessels clearer and easier to inject." Then, Yuan Fang took a cotton wool dipped in disinfectant alcohol and wiped Jiang Chengjia's arm, and at this time, Xiao Lu and Qin Cao had already put penicillin into the glass hanging bottle prepared by Yuan Fang before, and connected the sterilized hose and silver needle.

Yuan Fang changed the disinfectant cotton to wipe the needle and said: "We must pay attention to disinfection and avoid bacteria from entering the patient's body as much as possible." Then, Yuan Fang pinched the needle and pierced the blood vessels on the back of Jiang Chengjia's hand at an acute angle.

After fixing the needle and pointing to the blood return at the junction of the needle and the hose, Yuan Fang said: "This is normal, and it will flow back to the body when the tourniquet is untied and the injection begins, so don't care." As he spoke, he untied the tourniquet and loosened the caliper on the hose, and sure enough, as penicillin was slowly injected, the bright red color disappeared.

Yuan Fang fiddled with the hose for a while, controlled the flow at a steady and slow rhythm, and hung the hanging bottle on the shelf next to it and said: "The hanging bottle must be higher than the highest height of the patient, otherwise there will be a phenomenon that the blood return drug cannot be injected, as for what the principle of this is, I will not explain." ”

Xiao Lu looked at the silver needle with the hose attached to the back of Jiang Chengjia's hand, and then looked at the hanging bottle hanging high, and asked tentatively: "Brother Yuan, is this okay?" ”

Yuan Fang nodded and said, "Well, the injection has already begun, and this process will take a while." ”

Xiaomei, who rushed to hear the news, asked puzzledly: "Brother, why do you want to be full of drops?" Wouldn't it be faster to inject them all at once? ”

Yuan Fang smiled and said, "That's a good question. ”

Looking around at everyone, Yuan Fang explained: "Penicillin or other drugs that need to be injected in the future are mainly composed of water, when this water is injected into the blood vessels, the amount of fluid in the blood circulation will increase, and when this water slowly enters the blood, the human body will automatically adjust and discharge the excess water through the kidneys." However, if the infusion speed is accelerated, a large amount of water will flow into the blood, and the rapid and large inflow will make the body have no time to adjust, and then increase the burden on the human heart. If the patient has a bad heart, it is extremely easy to lead to heart failure, and for normal people, there will also be bad reactions, such as dizziness, vomiting, etc. Of course, this is only one of them, too fast can easily cause phlebitis, will also affect the efficacy and so on, everyone knows that these are enough. ”

Xiaomei nodded abruptly and said, "Oh, so that's the case." ”

Yuan Fang called Xiao Lu and instructed: "Xiao Lu, you work harder, you look at the dots during the injection, and if Jiang Er's sister-in-law has an allergic reaction, stop the infusion immediately." ”

Xiao Lu asked puzzledly: "What is allergies?" ”

Yuan Fang explained: "It is the rejection of the drug, and the symptoms are roughly redness and swelling around the skin, changes in the skin chu, self-conscious symptoms, etc., and soon the measures are to lie flat and replace the liquid with blank water, including the liquid in the infusion tube." Compress the acupoints such as the middle of the person, Neiguan, and ten seams, as well as artificial respiration, and external compressions. ”

Xiao Lu still knows what Yuan Fang said about artificial respiration and visceral compressions, Yuan Fang has taught everyone before, so he didn't explain much, as for those new old doctors, naturally there is Dr. Ye, an old and prestigious elder who solves their doubts.

After observing for a while, Jiang Chengjia had no adverse reactions, Yuan Fang breathed a sigh of relief, and suddenly remembered something and said to Doctor Ye: "By the way, I have to go out for a while after a while, this penicillin will please ask you to be old, and also, the efficacy of this penicillin is not very strong, and it may not be enough for serious patients, and I also have a purification method to make penicillin with higher purity and stronger efficacy." ”

Doctor Ye's eyes lit up, and he complained: "Don't grind, hurry up." ”

Yuan Fang smiled: "It's not convenient here, let's go to the workshop just now." Naturally, Dr. Ye would not object, and walked out of the ward with Yuan Fang and walked to the penicillin workshop.

Walking to the door, Yuan Fang looked back in surprise, and saw that Qin Cao, Chen Guang, Lu Ling and others were all standing in the distance and did not mean to follow, Yuan Fang asked puzzledly: "What are you doing there?" Not planning to stop by? ”

Lu Ling was stunned, she heard Yuan Fang say that it was not convenient to say in the ward, she thought that Yuan Fang wanted to avoid everyone, after all, this method is people's, and it is normal for people not to want to spread the word, and everyone else thinks so, so Lu Ling and the others are very conscious of staying outside.

In fact, Lu Ling and the others really misunderstood Yuan Fang, Yuan Fang's inconvenience was not because there were other people there, but because it was not easy to demonstrate, he didn't think about hiding his secrets, otherwise he wouldn't have disclosed the production method of penicillin.
