Next day.

Nine in the morning.

In the ward.

The next batch of neural stem cells hasn't been cultivated yet, and the surgery is scheduled for two days later. In the past few days, Professor Li Hongwei got the first batch of cultivated neural stem cells, and the follow-up work was handed over to his PhD students.

Zhao Heng has also returned to his normal work routine.

Today, Zhao Heng is on duty, responsible for handling emergencies and patients that the ICU can't manage.

"Dr. Zhao, it feels like things are back to normal."

Tian Zhen stood next to Zhao Heng, watching him type rapidly on the keyboard, and said with some emotion.

"Back to normal? Haven't we always been working normally?"

Zhao Heng was a bit puzzled and replied casually.

"I mean, these past few days, with you not being in the hospital, I wasn't used to it. Now that you're back, it feels normal again."

Tian Zhen said.

"Hmm... We might be staying in this ward for a long time, so be prepared."

Zhao Heng thought for a moment and said.

Anesthesia and perioperative care are his foundation and where he made his name; it's impossible for him to go elsewhere.

Moreover, although this ward only has ten beds now, this is just the beginning.

The treatment for Sun Xinxin set a good precedent.

The impact of treating Sun Xinxin is further spreading.

"Prepared for what?"

Tian Zhen asked.

"It will get busier in the future."

Zhao Heng said.

"Then by that time, won't you become the deputy director or even the director, Dr. Zhao?"

Tian Zhen asked expectantly.

"Even my teacher is still the deputy director, are you trying to get me into trouble?"

Hearing Tian Zhen's words, Zhao Heng smiled and said.

"It's only a matter of time."

Tian Zhen also said with a smile.

At this moment, the emergency department's resident doctor Wang Tao and a nurse came in pushing a stretcher, on which lay an elderly man who looked to be in his sixties, his face pale, breathing weak, eyes closed, and with visible red rashes on his face.

Following the stretcher was an elderly lady, also looking to be about sixty, her face full of anxiety.

Work arrived!

Seeing this scene, Zhao Heng saved his document and stood up.

"What's the patient's status?"

Zhao Heng, without exchanging pleasantries, asked directly.

"The patient is a 68-year-old elderly male with a medical history of hypertension and coronary heart disease for more than ten years. Before admission, due to a cough, he bought some syrup from the pharmacy, and about half an hour after drinking it, he experienced difficulty breathing, chest tightness, and red, itchy rashes began to appear on his limbs and face. The family called 120, and by the time the ambulance arrived, the patient was already unconscious."

"Emergency measures were taken on-site, but the effect was not very good."

The emergency resident doctor Wang Tao quickly explained the patient's condition.

"Hmm, what medications were administered on-site?"

Zhao Heng asked.

From Wang Tao's description, Zhao Heng initially suspected an allergic reaction, but the exact cause was still unclear.

"The on-site doctor recorded the blood pressure as 65/43mmHg, and considering it an anaphylactic shock, they immediately established an IV, administering epinephrine and dexamethasone while providing fluid resuscitation."

Wang Tao replied quickly.

"Alright, leave this to me now."

Hearing Wang Tao's report, Zhao Heng nodded.

In all respects, this patient showed classic symptoms of anaphylactic shock.

"Okay."

Wang Tao nodded to Zhao Heng, turned around, and left with the nurse; the emergency department was very busy, and Wang Tao had many responsibilities.

If it weren't for the emergency department being at full or even overcapacity, ordinary emergency patients wouldn't be sent to Zhao Heng.

In fact, not just at Eastern Hospital, emergency departments are operating at full or overcapacity nationwide in all top-tier hospitals.

It's a common scenario for emergency doctors to be working continuously for 24 to even 48 hours.

"What cough syrup did the patient take earlier?"

Zhao Heng asked the elderly lady standing to the side, who looked anxious and uneasy.

The first thing is to figure out exactly what the patient consumed to find the cause of the allergy and treat it accordingly.

"Doctor, I brought the bottle with me, have a look."

Upon hearing Zhao Heng's question, the lady quickly took a bottle from her pocket and handed it to Zhao Heng.

"Okay."

Zhao Heng took the bottle and examined it carefully.

**Loquat syrup?

Seeing the label, Zhao Heng was a bit surprised.

Loquat syrup is considered one of the safer cough medicines; there's rarely any report of allergic reactions, much less cases leading to anaphylactic shock and coma.

Therefore, it's very possible that this severe anaphylactic shock wasn't caused by the syrup.

Thinking of this, Zhao Heng asked the lady once again, "Has the patient ever been allergic to any medication, or had any reactions to something eaten or injected?"

"Not that I know of, doctor."

"He eats everything, even fish, shrimp, and crabs."

The elderly lady thought carefully and replied.

"Hmm, please think again, has there ever been such an incident after taking medicine or receiving an injection?"

Zhao Heng was not satisfied with her response and continued to probe.

"Hmm..."

"Oh, doctor, a couple of years ago when getting an IV at a clinic, I remember Old Ma said his skin felt itchy for a while, but we didn't do anything, and it got better by itself."

After thinking hard for a moment, the lady said again.

Upon hearing this, Zhao Heng became instantly alert and immediately asked, "Do you remember what the injection was?"

The lady frowned, thought hard, and squinted her eyes to say, "I'm not really sure... I think it was cephalosporins..."

Cephalosporins?!

Hearing these words, Zhao Heng felt like he'd been hit by lightning.

"Did he take cephalosporins today?"

Zhao Heng asked urgently.

"Old Ma has been coughing these days, I think he did."

The woman tried to recall, but seemed uncertain.

Beep beep beep!

At this moment, the life monitor sounded a piercing alarm, and when Zhao Heng turned around, the monitor was flashing red.

"Dr. Zhao, the patient's blood pressure is 50/30mmHg."

Tian Zhen said urgently.

Looking at the pale elderly man still lying on the stretcher, Zhao Heng immediately stepped forward and grabbed his right wrist.

No pulse on the right side!

Zhao Heng was instantly alarmed.

"One unit of epinephrine, dopamine infusion, prepare for intubation."

Zhao Heng instructed Tian Zhen.

"Alright."

Tian Zhen nodded and promptly went to prepare.

"Doctor, please save Old Ma!"

Seeing this, the elderly lady felt a darkness before her eyes, her heart twisted in fear, and she pleaded urgently with Zhao Heng.

"Please sit here and rest; leave the patient to me."

Zhao Heng, seeing the lady about to collapse, quickly helped her to a seat nearby, offered brief comfort, and dove back into the emergency procedures.
