Chapter 2239: 2161 Explosion Sound in the Operating Room

Su Yun was stunned for a moment; her first thought was that the oxygen pipe had exploded.

But the sound didn't match; it was somewhat muffled. If the oxygen pipe had burst, the sound couldn't be this small. In a flash of thought, 0.2 seconds later she saw Zheng Ren stride toward a treatment room at the back.

Su Yun quickly followed Zheng Ren, with no time to ask what was happening; a glance told her everything.

If something major happened in the operating room, whether doctors and nurses would get hurt is one thing; after anesthesia the patient lies on the operating table, yet has no chance to run.

It was said that a certain hospital caught fire, a patient died on the operating table, and the incident caused a huge public outcry at the time.

Fire, power loss — even if doctors and nurses stayed put, those many instruments simply couldn't operate……

For such things, it's best to pray never to encounter them.

The door of the treatment room where the sound came from was open, and Zheng Ren strode in.

Inside the treatment room, several people looked bewildered; the patient was in the lithotomy position. Looking at the posture and the patient's system panel, Zheng Ren knew this was a transurethral resection of the prostate.

Zheng Ren saw the patient also looking around in panic; that "bang" sound had frightened him. The patient's face showed bewilderment and fear, his hands waving continuously, as if trying hard to sit up.

But he had strength in his upper body, none in his lower, making his posture look strange.

"Lie still, it's fine." Zheng Ren was the first to regain his composure; he strode to the patient's side and restored his position.

Had Zheng Ren not reacted in time, the patient might have fallen off the operating table in a few seconds.

The thought of such a fall from the table… just thinking about it gives me a headache.

Looking at the patient's system panel, Zheng Ren pondered for a few seconds. Only when the circulating nurse reacted, stopped lightly tapping the surgical instruments, and came over to help secure the patient.

"Don't worry, it's fine." Zheng Ren tried to make his tone gentle, then gentler still.

Seeing the circulating nurse arrive, Zheng Ren finally released the patient, saying, "It's normal; if you jump at every little scare and fall, what then?"

"Doctor, is everything okay?" the patient asked anxiously.

"It's fine, don't worry." Zheng Ren comforted the patient; although it was a lie, he spoke it as if it were true.

Speaking nonsense with eyes closed, Zheng Ren's skill was nearly master‑level.

The patient has coronary heart disease; if we told him the truth, what if he got tense or excited and suffered a heart attack?

"What's going on?" Zheng Ren approached Yu Zong, who wore a bewildered expression, and lowered his voice to ask.

Yu Zong stood in the assistant's position; to the surgeon Zheng Renhe looked like a pixelated face.

Seeing the stable numbers on the ECG monitor, everyone's tension eased; they cracked a couple of jokes, which not only relieved the operating room's tension but also helped the patient calm down.

Director Liu? He's the new director who took over after Director Miao retired. Zheng Ren gave a forced smile as a greeting, then his eyes turned to Yu Zong.

"The surgery was almost done when suddenly there was a bang." Yu Zong hadn't lost his composure; he replied softly.

"It's fine," Director Liu said calmly,

Zheng Ren glanced around and immediately realized the surgery had reached the Ellik irrigation step, excising the resected tissue and achieving complete hemostasis.

Only about one or two minutes remained until the end.

But just then, something went wrong. Director Liu remained remarkably calm; he had collected himself and resumed the hemostasis.

"Boss Zheng, how did you come up here?" Yu Zong, a bit flustered, tried to make small talk to steady his heart, which had raced to 130.

"I just did a case with thoracic surgery — a pneumothorax caused by endometriosis." Zheng Ren looked at the patient, a possibility occurring to him, and gave an offhand reply.

「We handled a case of pneumothorax caused by endometriosis with the thoracic department. 」 Zheng Ren looked at the patient, a possibility occurred to him, and he casually gave a perfunctory reply.

Director Liu and Yu Zong both stared for a moment.

Thoracic department? A pneumothorax from endometriosis? That's too rare, right?

How does endometriosis get into the thoracic cavity? Yu Zong's mind raced with gossip, but he quickly suppressed it.

The patient before us has a problem; figuring out what that muffled sound was is enough to worry about — who has the energy to meddle in others' affairs?

Zheng Ren had a hypothesis; guessing the cause of that muffled sound wasn't hard — whether it was Su Yun, Director Liu, or Yu Zong, they should all realize — consider an explosion of mixed flammable‑explosive gas in the bladder causing bladder rupture.

Bladder gas explosion is a rare complication of transurethral prostate resection; domestic reports have appeared in recent years, while overseas reports are more numerous, and some doctors have conducted large‑scale surveys, finding an incidence of roughly 1 in 1500.

Experiments show that intracellular water electrolysis produces hydrogen accounting for about 30‑50%, oxygen only about 3%; it is generally believed that hydrogen mainly comes from the electrolysis of intracellular water.

When the volume of hydrogen in the air occupies 4%‑74.2% of the mixture, ignition will cause an explosion.

And that "bang" we just heard could be, during TURP, vaporized prostatic tissue generating various explosive gases; during electro‑cutting and electro‑coagulation, intracellular water electrolysis produces hydrogen that explodes inside the bladder.

The ignition source is the hot metal loop of the resectoscope sparking upon contact with tissue.

During surgery, oxygen reaching flammable or explosive concentrations may be due to air entering the bladder with the Ellik irrigation.

The consequences of bladder gas explosion vary; mild cases show no obvious damage, severe cases can involve multiple bladder ruptures.

Zheng Ren watched Director Liu's confident expression and tone while he was still finishing hemostasis; he too felt a bit dazed.

Could it be that Director Liu has encountered something like this before? Or does he also have a system, having checked the patient's bladder early on and confirmed there was no serious problem?

Carrying these doubts, Zheng Ren re‑entered the system space, selected to purchase surgical training time, and entered the system operating room.

The experimental subject in the lithotomy position lay on the operating table, far more docile than the real patient.

Zheng Ren glanced with the resectoscope; the bladder wall was collapsed, bleeding. Looking closely, the breach was only a few millimeters — should be fine.

No wonder Director Liu remained so calm.

But the explosion could cause one or more bladder injuries; Zheng Ren set down the resectoscope and began to puncture the patient.

Extraperitoneal aspiration yielded clear fluid. Considering that an explosion of mixed flammable‑explosive gas in the bladder could cause bladder rupture,

The urine volume was small, about 40 ml drawn out.

Zheng Ren frowned; if it were him, he'd surely step down and explain the situation to the patient's family, converting to an open surgery mid‑procedure.

Only by opening up to look would be safest. Under metal‑frame guidance, a Fr22 three‑way balloon catheter was left in place, draining a pale‑red fluid.

There should be a problem; Zheng Ren confirmed his view.

Fortunately it was the system space; Zheng Ren hesitated not, began to lay out the orders, and converted to an abdominal operation.

Fortunately it was the System Space; Zheng Ren, without hesitation, began laying out the sheet and proceeded to open abdominal Shou Bing
