Shi Wan immediately went forward to check on her. When Song Zhiqing saw the doctor, she clutched her neck and struggled to speak, "Doctor... my neck feels tight, and I can't breathe properly. What's wrong with me?"

"Have you ever had any drug allergies before?" Shi Wan asked, turning off the IV tubing clamp, taking the oxygen tube from Zhang Xiaowan, and giving Song Zhiqing oxygen.

Song Zhiqing shook her head: "No, this is my third day of IV infusion. The IV fluids I had for the first two days were the same as today's, but after this IV fluid was changed today, I started to feel uncomfortable, couldn't breathe, and broke out in a cold sweat."

Shi Wan frowned. Song Zhiqing had no history of drug allergies, and it was the third day of receiving the same IV fluids. So what was causing her breathing difficulties?

"Is your body itchy?"

The IV drip set was checked that evening, but no abnormalities were found. While considering the possible causes of the infusion reaction, the doctor issued the following orders:

"Xiao Wan, change the IV set. Infuse 250 ml of 0.9% saline solution at 40 drops per minute intravenously. Keep the original IV set and fluid."

"Received, 250 ml of 0.9% saline solution, 40 drops per minute, intravenously." Zhang Xiaowan repeated, confirmed with Shi Wan that it was correct, and then, after double-checking with Li Jingru, began the replacement.

Song Zhiqing's condition was getting worse and worse. She was having more and more difficulty breathing. She was clutching her neck with one hand, her face was pale, and her lips were bluish-purple.

"Song Zhiqing! Song Zhiqing!"

Shi Wan called out twice, but there was no response.

"Jingjie, adjust the oxygen flow rate to 4 liters per minute, connect the monitor, and report the blood pressure value!"

"Received." Li Jingru adjusted the oxygen flow, put on the monitor, and began measuring blood pressure.

When Shi Wan called Song Zhiqing again, there was no response. At this time, Song Zhiqing was indifferent, her lips were cyanotic, her pupils were round and equal in size, about two millimeters in diameter, and her pupillary light reflex and orbital pressure reflex were present. Auscultation revealed tachycardia, rapid breathing, moist rales at the bases of both lungs, a thin and rapid pulse, cold and clammy skin on her extremities, and many patchy rashes on her body. Shi Wan considered it to be anaphylactic shock.

Meanwhile, Li Jingru reported the blood pressure readings she had just taken: "The patient's systolic blood pressure is 79 mmHg and diastolic blood pressure is 51 mmHg, pulse is 113 beats per minute, respiration is 28 breaths per minute, and pulse oxygen saturation is 81 percent."

Shi Wan frowned and gave the doctor's order: "Xiao Wan, 1 mg of 0.1% epinephrine hydrochloride subcutaneously."

"1 mg of 0.1% epinephrine hydrochloride subcutaneously," Zhang Xiaowan repeated, and after verifying with Li Jingru, she began the subcutaneous injection.

"Jingjie, insert the urinary catheter, report vital signs every two minutes, keep the patient warm, position them in a semi-recumbent position, and monitor urine output," Shi Wan said.

"receive."

Li Jingru quickly inserted a urinary catheter, and only less than 20 milliliters of pale yellow urine flowed out of the urine bag. She brought a quilt from the next bed and added it to Song Zhiqing's bed, then raised the head of the bed by about 30 degrees and the bed height by about 20 degrees.

Song Zhiqing was still pale and her limbs were cold and clammy. Shi Wan adjusted and sped up the saline solution flow, and gave the doctor's order: "Xiao Wan, open another intravenous line, administer 60 drops of lactated Ringer's solution intravenously per minute, and 10 mg of dexamethasone sodium phosphate intravenously."

Zhang Xiaowan repeated the instructions, reopened an intravenous line, checked with Li Jingru, and then started the IV fluids and medication.

Two minutes passed quickly, and Li Jingru reported again: "Systolic blood pressure 85 mmHg, diastolic blood pressure 57 mmHg, pulse 110 beats per minute, respiration 26 breaths per minute, and pulse oxygen 81%."

After examining Song Zhiqing again that evening, Shi Wan said, "Xiao Wan, administer 25 mg of promethazine hydrochloride intramuscularly."

Zhang Xiaowan repeated the instructions, and after verifying them with Li Jingru, Shi Wan helped Song Zhiqing assume a side-lying position to facilitate Zhang Xiaowan's injection.

Two minutes later, Li Jingru reported the latest vital signs again: "Systolic blood pressure 85 mmHg, diastolic blood pressure 57 mmHg, pulse 110 beats per minute, urine output still 20 ml."

Shi Wan quickly administered the following: "Xiao Wan, administer 38 ml of 0.9% saline solution and 100 mg of dopamine via microinfusion pump at a rate of 3 ml per minute."

"Received." Zhang Xiaowan repeated, checked with Li Jingru, prepared the liquid, connected the micro pump, and pumped in the medicine.

Shi Wan closely observed Song Zhiqing's condition. Five minutes later, Song Zhiqing's cyanosis of the lips finally improved, and the skin temperature of her hands and feet warmed up. Shi Wan called out to her again, "Song Zhiqing? Song Zhiqing? Are you feeling any better now?"

Song Zhiqing blinked, her reaction a little slow, and said slowly, "I feel a little better, but I still feel tightness in my chest and palpitations."

Li Jingru reported again: "Systolic blood pressure 99 mmHg, diastolic blood pressure 61 mmHg, pulse 90 beats per minute, respiratory rate 24 breaths per minute, pulse oxygen 93%, urine volume in urine bag 200 ml."

Zhang Xiaowan and Li Jingru looked at each other and both breathed a sigh of relief.

Not only Zhang Xiaowan and Li Jingru breathed a sigh of relief, but Shi Wan also breathed a sigh of relief, as the shock had been basically corrected.

After another ten minutes of waiting, Song Zhiqing gradually calmed down and her breathing became easier.

Shi Wan tucked Song Zhiqing in and gently comforted her, "Your condition has stabilized now. If you feel unwell, please press the call button by your bedside..."

Before Shi Wan could finish speaking, Song Zhiqing interrupted her, frowning as she asked, "What happened to me just now? Doctor, you have to tell me the specifics!"

Shi Wan patiently explained, "What happened to you just now was an allergic reaction to the medication during the IV infusion."

Upon hearing this, Song Zhiqing's face fell instantly, and a look of panic flashed in her eyes, filled with suspicion: "How could it be a drug allergy? I've been receiving the same IV drip for two days already, and I even had a skin test before the IV drip the day before yesterday. How come I didn't have an allergic reaction yesterday and the day before, but I had an allergic reaction today?"

Did you get the injection solution wrong?

Song Zhiqing didn't dare say those words. She was still in the hospital and hadn't fully recovered. What if she was retaliated against if she said it?

She has no family members with her. What if they do something that leads to her death? There are no security cameras here, and even if there were, they wouldn't be available for outsiders to see. No one can see her, and no one can testify for her!

A couple of days ago, she saw a video on the internet where a young man sprained his ankle and went to the hospital. Suddenly, he was brain dead. The doctor even asked his family to sign an organ donation form. Then, 30 minutes later, a powerful old man who was about to die had a successful lung transplant. It's really terrifying to think about!

Thinking of this, Song Zhiqing looked at the row of doctors and nurses surrounding her bed, her eyes filled with fear!

Next time she gets sick, she must bring a family member with her to the hospital. Otherwise, like in the situation just now, she was like a fish on a chopping block, her life and death entirely in the hands of the doctor, and she didn't even know how she died.
