When the Doctor Uses A Hack-Chapter 806: Mother’s Self-Blame (5—The Tiger That Walks Like a Cat for the Alliance Hierarch, 3 More)

At that moment, the ambulance was already speeding along.

But for some reason, Ma Yuehui still felt it was too slow!

He wished Ferrari would start manufacturing ambulances!

No, that's not right!

He thought there should be a new event on the F1 race track, a competition for ambulance speed.

Seeing the sweat on Ma Yuehui's head, which resembled the sweat from yang deficiency, Xu Aiqing took a deep breath and felt he should give some advice to this old big brother team leader, "Old Ma, let me give you a suggestion."

Ma Yuehui was startled, turned around, and looked at Xu Aiqing, "What suggestion?"

Xu Aiqing said earnestly, "You're not young anymore, pay attention to taking care of yourself. Being this weak... I'm not trying to criticize you... but which man at forty is this weak? I really should talk to your wife about this some day!"

Upon hearing this, Ma Yuehui was stunned, and it took a moment for him to comprehend.

But someone else reacted, the patient lying in the ambulance couldn't help but laugh out loud, "Hahaha... ouch, ouch! Doctor, look, I'm bleeding, I'm bleeding!"

The patient, who had been busy laughing, suddenly wondered if his wound had reopened?

Ma Yuehui then realized too and gave the patient a glance, really wanting to say 'serves you right!'

…

…

Chen Cang looked at Qin Fang and her husband, explaining the entire situation, "This is the situation now; the decision is still up to you!"

Qin Fang's husband looked at Chen Cang, took a deep breath, "Doctor, I trust you!"

Qin Fang nodded too, "Go ahead with the procedure; I also do not wish for the child's future..."

Watching their trusting eyes, Chen Cang nodded and turned to leave, but as he did, Qin Fang behind him had already started to weep quietly.

Perhaps this could be her and her child's last reunion...

And Chen Cang also felt the heavy trust and hope.

This battle, a must-win!

…

In the operating room, anesthesiologist Zhou He had already started preparing.

To properly conduct such a surgery on a mere 5-year-old child, he had to consider everything!

Meanwhile, Zhang Yuan and Yang Hui had already started sweating!

Chen Cang saw their caps were wet and curiously asked, "Are you very nervous?"

Zhang Yuan was caught off guard, almost didn't know whether to laugh or cry, it was exhausting!

More uncomfortable than being nervous!

For the first time, they looked forward to the operation starting quickly!

The anesthesia gradually took effect, and Chen Cang watched as the child's red eyes closed, taking a deep breath.

He took the scalpel from the nurse's hand.

In the nurse's encouraging and affectionate gaze, Chen Cang held it tightly.

Such surgery, Chen Cang had done countless times in the special training space, proficiently.

This surgery had time constraints; if it took too long, it could cause necrosis of the cardiac muscle cells, and various complications could ensue!

A standard thoracic incision began!

Then decisively cut open the pericardium!

Practically no different from a normal surgery!

The objective of the surgery could be simply stated as, two one-way doors of the chambers were damaged, originally an integral system working smoothly under the hinge's motion.

But now, these doors were damaged and partially disconnected from the hinge.

At this moment, it was necessary to sew the door back together with sutures.

Of course, one could also replace these doors entirely!

But then, it'd no longer be mitral valve repair surgery; it would be mitral valve replacement surgery.

Since the 1960s when artificial valves were introduced clinically, valve repair was almost replaced by valve replacement.

However, experience showed that artificial valves were not ideal and posed certain inherent risks, and in recent years, the trend has been shifting back toward valve repairs.

The goal of mitral valve repair surgery is to restore the physiological function of the mitral valve, specifically correcting the insufficiency caused by valvular pathology.

In this case, choosing valve repair surgery not only costs less but also promises significantly better long-term results!

Do not underestimate this valve; it is costly, although tiny… and appropriate for this family who had moved to Beijing for work, something Chen Cang had to consider.

Actually, sometimes, doctors have to consider a lot more than just treating the disease!

Watching the steadily beating heart, it was Yu Yonggang who suggested opting for hypothermic surgery to reduce the difficulty.

A nurse looked at Chen Cang, timing the procedure, "Dr. Chen? Shall we start?"

Chen Cang inhaled deeply, "Begin!"

The clock began the countdown of 15 minutes for the procedure!

Even if the surgery couldn't be completed on time, they had to give up.

Time began to flow furiously like sand through an hourglass.

Chen Cang's eyes fixed on the heart, choosing the incision point.

Zhang Yuan, who was holding the retractor beside him, also felt uneasy. This was the first time in his life he had witnessed a beating-heart surgery. He was nervous.

Yu Yonggang felt the same way. He had been studying the series of beating-heart surgeries for years, but he was just a novice.

He hadn't expected Chen Cang to perform it!

For Yu Yonggang, this was somewhat exciting.

Zhou He's eyes were fixed on the patient's vital signs, ready for any contingency.

Not a single person in the surgery dared to slack off!

After opening the heart, Chen Cang decisively searched for the mitral valve!

There was absolutely no time for hesitation.

With the help of the system, Chen Cang quickly located it. He had prepared using a four-dimensional echocardiogram but suddenly realized he had underestimated the extent of the damage to the mitral valve!

The chordae tendineae of the mitral valve had ruptured!

Especially the rupture of the main chordae of the anterior leaflet, what to do?

Chen Cang said directly, "The chordae tendineae of the mitral valve are ruptured!"

Yu Yonggang was immediately shocked inside. A rupture of the chordae was not good news.

"Should we switch to a cardiopulmonary bypass machine?" Old Yu frowned as he looked at Chen Cang.

Once a chordae rupture occurred, in addition to repairing the damaged leaflets, an artificial chordae needed to be established!

This process, even under open chest, would take about ten minutes at least, right?

Old Yu was genuinely worried!

Yet Chen Cang calmly shook his head and said, "It's not needed."

This left Yu Yonggang momentarily stunned!

At this moment, if Tao Zi and the others were present, they would definitely say, "Yikes! Look, look, Chen Cang is about to show off!"

...

Chen Cang, unhurried, turned to the nurse and said, "4-0 expanded polytetrafluoroethylene suture!"

The nurse quickly nodded!

After hearing this, Yu Yonggang stared at Chen Cang, this guy… planning to perform artificial chordae replacements under a beating-heart condition!

Replacing the ruptured chordae to correct the mitral valve insufficiency.

What audacity!

Then, Chen Cang, holding the suture needle, was very steady! Very calm, and also very skillful!

With the 4-0 expanded polytetrafluoroethylene suture, he rapidly and precisely attached the patch to the middle muscle of the papillary muscle!

He then sutured to the edge of the leaflet where the chordae had ruptured and then adjusted the length of the suture before knotting it.

This series of procedures sounded simple, but it was much more difficult than one might imagine!

Yu Yonggang kept turning to check the time!

And the nurse kept reminding about the time: "12 minutes left... now…"

With the rhythm of the beating heart, Chen Cang's suturing became faster!

The key to the operation was adjusting the length of the artificial chordae so that it was neither too long, causing leaflet prolapse, nor too short, restricting the leaflet movement!

Thus, the difficulty of the surgery was far greater than imagined, and moreover… the most critical aspect was that the heart was still beating!

The difficulty of suturing was terrifying to even think about!

Yu Yonggang watched Chen Cang's hand speed like a butterfly fluttering through flowers, like a magician playing with cards!

And the young nurses watching Chen Cang's dexterous hands, swiftly moving fingers, and steady, strong arms somehow felt a bit flushed!

"10 minutes left!"

"9 minutes left!"

At this moment, Chen Cang took a deep breath: "Change the thread!"

Yu Yonggang was taken aback, watching Chen Cang, "Is it done?"

Chen Cang nodded, with a slight smile: "Yes!"

Suddenly, everyone was shocked.

Even Zhou He incredulously watched Chen Cang; that was just... not even six minutes, maybe seven?

...
