Rash, which is a symptom that can be easily overlooked by the average person. Not everyone will or have the ability to scrutinize every part of their body skin. Moreover, there are so many forms of rash that the rash can manifest, and there are many types of clinical descriptive terms such as: plaque, wheal, pustule, blister, nodule, ulcer, cyst, erosion, and so on. Patients themselves vary. With the same descriptive noun, some patients may feel extremely itchy on their foreheads, some may be excruciatingly painful, some may feel slight discomfort, and some may not feel at all.

Depending on the type of rash and how the patient feels, the rash may be one of the suggestive manifestations of a variety of diseases. And a large proportion of these diseases are infectious.

This is also the reason why Zhong Yu asked Xiao Guo to call Sun Lien over immediately - now Qian Aiwu is using a large number of antibiotics every day, if these rashes are infectious, then it will be a big trouble.

Under the action of two powerful broad-spectrum antibiotics that are restricted, if there are any bacteria that can infect Qian Aiwu, it must be some kind of bacteria that have developed a multi-drug resistance reaction. And Qian Aiwu's own physical condition is not very good, and her necrotizing fasciitis recovery speed is relatively slow. What if there was another multidrug-resistant bacterium now...... Sun Lien had no doubt that she might die on this.

"Dr. Sun. Half a minute later, Sun Lien appeared in Qian Aiwu's hospital room. The head nurse, Zhong Yu, nodded at him, pointed to the back of Qian Aiwu, who was lying on the bed, and said, "Come and see." ”

Sun Lien said hello to Qian Aiwu, "Aunt Qian, I heard from the nurse that you have a rash on your waist, is there anything uncomfortable?"

Qian Aiwu's reaction was a little slow, she slowly turned her head and looked at Sun Lien's face. After a few seconds, he shook his head, "It's okay." ”

What is the description? Sun Lien was stunned, and then glanced at the status bar above Qian Aiwu's head - the previous state handwriting was already very faint, and it looked like it should disappear in a few days. However, there is an extra line at the end of the status bar, "Headache (00.34.24)"

"Does it hurt?" Sun Lien carefully lifted the quilt and looked at the skin on Qian Aiwu's back - there were many reddened areas scattered on this area, and there was a raised white lump in the center of the red skin. This is typical of wheals and is generally common in hives.

"It's a bit of a headache. Qian Aiwu said in a low voice, "And ...... It's itchy. ”

Sun Lien took a closer look at the wheal area and found no scratched skin lesions, "How itchy is it?"

Qian Aiwu shook his head, and his speech seemed very difficult, "Hurry up...... Can't help it. ”

"Get her two tablets of loratadine and open a bottle of calamine lotion. Sun Lien thought for a while and said to Zhong Yu, "Let's stop the itch first." ”

"You're doing a great job. Sun Lien turned his head and encouraged Qian Aiwu, "This will definitely be very itchy, just hold back and not scratch it." Bear with it a little longer, and it won't itch anymore soon. ”

"Wheals?" Sun Lien called Jiang Lun, a dermatologist he had met before, in the office, and after listening to Sun Lien's description breathlessly on the other end of the phone, he asked, "Have you done an acetylcholine test?"

"Not yet. Sun Lien frowned and asked, "Doctor Jiang, are you not very convenient now?"

"Lao Tzu is being slipped ...... by a dog" Dr. Jiang Lun's voice sounded painful, "Ge Lao Tzu, a dog runs faster than a dog!"

Sun Lien unconsciously thought of the husky who could run very well, and the appearance of Dr. Jiang who was dragged by the husky and ran behind. He suddenly laughed, "Well, then Dr. Jiang, you should be busy first, and when you finish walking the dog, I will contact you again." ”

After hanging up the phone, it took Sun Lien a long time to digest the image in his mind - Dr. Jiang was not tall, thin, and did not have much strength. was dragged around the street by a big dog all the time, and the impact of the picture is really strong.

However, there is some value in this incomplete consultation request. The question Dr. Chiang mentioned on the phone was crucial – the acetylcholine test.

Qian Aiwu's wheal should not be related to the initial posterior necrotizing fasciitis. For this judgment, Sun Lien is very confident. However, because wheals are generally closely associated with allergies, it is unlikely that the infection will cause the wheals. Sun Lien suddenly had no confidence.

Bedding and equipment for hospital beds may not be very comfortable, but they are generally made of "safe" items.

Yes, the emphasis is on "security". The bedding in the hospital basically follows the basic requirements of "pure cotton fabric" and "cloud silk shaped cotton". The four hospitals have taken this standard a step further and uniformly required that all bedding in the inpatient department must be Class A products that infants and young children can directly contact, rather than Class B products that are in direct contact with the skin.

The price of Class A products is more expensive than Class B, and in order to reduce the cost of procurement, the bedding of the Fourth Courtyard has much weaker requirements for comfort. However, this quality requirement basically ensures that patients will not have an allergic reaction to the bedding. Qian Aiwu should not be allergic to cotton fabrics. If it was for this reason, she would have had an allergic reaction a long time ago.

"What does the acetylcholine test mean...... This allergy may be related to acetylcholine?" Sun Lien did not grasp the content of dermatology very well, but the basic concepts were still there. When acetylcholine and wheals are put together, the answer is only acetylcholine urticaria.

It is not difficult to confirm the diagnosis, after a skin test of 1:5000 acetylcholine injection, if the patient has severe erythema, it is considered a positive reaction. However, what made Sun Lien feel a little difficult was the meaning of this disease.

Stress or depression can induce acetylcholine urticaria, which can also be caused by exposure to allergens. But according to Sun Lien's judgment, the possibility of allergies causing hives is very small.

Qian Aiwu's meals during this period were all provided in the hospital canteen. The dishes are exactly the same every day, and food allergies can be ruled out. The medication also lasted for more than a week, and there was no change except for the subsequent addition of vancomycin.

Vancomycin...... Sun Lien frowned, and he took out the instructions for vancomycin from the information on the side. Then the brow furrowed even deeper.

"Hey, Sun Lien?" Sun Lien made a phone call and went out, and Director Han Wenping answered the phone very happily, "It's not time yet, right? ”

"Director Han, let me ask you about something. Sun Lien said solemnly, "Is it possible that the allergic reaction caused by vancomycin will occur chronically?"
