After binding with the system, I became a proctology expert.

Lu Renxin saw a small, pulsating blood vessel.

He deftly threaded the absorbable suture with his fingers and clamped the needle holder.

Insert the needle into the healthy mucosa about 0.5 to 1.0 cm above the bleeding point.

"Oh."

The patient's body trembled slightly.

Lu Renxin's voice was serious, his tone low and harsh, completely different from his usual amiable manner, carrying an air of authority:

"Don't move around. If the needle goes astray, I'll have to give you another one."

The patient froze instantly, too afraid to move.

Lu Renxin continued to insert the needle, penetrating deeper into the submucosa to ligate the underlying blood vessels.

Then the needle came out again, and he tied a surgical knot tightly.

Upon removing the hemostat and observing, the bleeding stopped quickly after the blood vessel was completely closed.

He instructed the patient, "Okay, don't get up. Lie down and observe for a while longer."

After finishing with his own patient, Zhang Wenhua quietly stood behind Lu Renxin to observe his procedure.

Lu Renxin performed the entire procedure smoothly and calmly, clearly understanding the precautions for each step, showing no signs that this was his first time stopping a hemorrhage.

After he finished sewing, Zhang Wenhua couldn't help but praise him, "Very good, your skills are almost as good as mine."

The two patients had been settled in, one on each side of the bed, while Lu Renxin sat in the middle.

He stood guard here, watching the two great figures, fearing that something else might go wrong.

But what I feared most came to pass; Li Lanli's voice preceded her arrival:

"Old Zhang, are you still there? Another patient with bleeding has arrived."

What?! Another patient has arrived!

The door to the dressing room was slammed open again.

Busy to the point of feeling lost and beginning to question the meaning of life, Li Lanli brought in her third patient.

Lu Renxin couldn't help but rub his forehead, his face full of unspeakable frustration:

From now on, if I ever eat or drink recklessly while on night duty again, I'm a pig!

……

Fortunately, the third patient did not need stitches. Lu Renxin only needed to apply slight pressure and sprinkle some hemostatic powder to finish the job.

After the chaos of war, the two finally returned to their office and collapsed into their chairs.

The delivery guy had already called, but they didn't have time, so they could only ask him to leave the dinner on his desk.

Now, dinner has completely cooled down.

Lu Renxin and Zhang Wenhua looked at each other, their eyes filled with a thousand kinds of helplessness.

Let's eat. Eating is the most important thing in the world. I just hope there won't be a fourth one.

Of the three patients, Lu Renxin only performed the initial auxiliary work, and the system gave him 1 point of treatment value accordingly.

The latter two were where he was the main force; the one who received stitches received 6 healing points, while the one who only received pressure received 3.

If nothing else happens, today's income would be 11.6 points.

Of course—that's impossible.

He also treated three patients with fever, five with pain, and two who couldn't urinate after anesthesia...

These patients were prescribed medications but did not undergo any treatment procedures, therefore they did not generate any additional income.

At 11 p.m., Lu Renxin, who was sleeping soundly in the duty room, was woken up again.

Of the two people who had difficulty urinating, one has successfully urinated, while the other still cannot.

If a patient undergoes surgery at 4 PM and does not urinate within 6 to 8 hours after anesthesia, the possibility of urinary retention should be considered.

Lu Renxin got out of bed, put on his white coat, and hurried to bed 32.

In addition to roughly determining the possibility of urinary retention based on the time elapsed, he also needs to undergo a physical examination.

He had the patient lie flat on the bed, relax his body, and bend his knees.

Starting above the pubic symphysis, percuss downwards, using changes in sound to determine the boundaries and fullness of the bladder.

This is a voiced sound, and that is a voiced sound...

The bladder of patient in bed 32 is now very full, like a water-filled balloon. We can't wait any longer; we must immediately insert an indwelling catheter.

Otherwise, the bladder will continue to expand until it exceeds the elasticity and tolerance of the muscle fibers, eventually rupturing.

In addition, prolonged retention of urine in the bladder can lead to bacterial growth and cause cystitis.

The infection can also ascend to the kidneys, leading to conditions such as pyelonephritis.

Although doctors don't see gender, most patients still mind others seeing their private parts.

In their department, female patients are catheterized by nurses, while male patients are catheterized by doctors.

Bed 32 requires Lu Renxin to operate it.

The nurses' station was still brightly lit. The battle-hardened Li Lanli had anticipated this and prepared a catheterization kit and 20ml of saline solution in advance.

She couldn't help but complain, "I'm so unlucky to be working with you two tonight."

Lu Renxin smiled wryly: "This can't be blamed on us, Sister Lan. It's just an unavoidable situation."

He returned to the ward with his belongings, turned on the main light, and the patient in bed 31, who had just woken up from the light, rubbed his sleepy eyes and asked:

"Dongzi, you're still a child at heart."

Beds 31 and 32 are best buddies who specifically requested this double room to come for surgery together.

They call it mutual help, but true best friends are those who have seen each other at their most vulnerable.

They truly are friends; they even experienced urinary problems together after surgery.

Lu Renxin had prescribed medicine for both of them before.

Unfortunately, it works for one person but not for the other.

The sight of bed number 32, with its trousers pulled up, struggling to climb into bed, looked particularly poignant.

He had just finished his last attempt before Lu Renxin arrived—which failed.

I'm terrified and nervous right now. Please, this is catheterization.

Having surgery already affected the anus, and now they're going to attack the man's very core. It's like adding pain upon pain, suffering upon suffering.

His tone was filled with grief and helplessness:

"Yes, still no. Now I have to use a catheter!"

Bed 31, with a "the more the merrier" mentality, gloated:

"Ouch, thank goodness I peed, otherwise I would have ended up like you."

Bed 32 was subjected to a heart-wrenching attack from his best friend: "Get lost, you were clearly so scared you peed your pants."

"So what? You're the one who's going to suffer now anyway."

"you……"

Ignoring their banter, Lu Renxin put on gloves and performed initial disinfection.

He has rotated through many departments and is a seasoned veteran, having inserted countless tubes.

After disinfection, remove gloves and open the sterile catheterization kit for further disinfection and lubrication.

Hold the catheter with sterile forceps and gently insert it into the urethral opening.

Bed 32 strained to keep her eyes glued to Lu Renxin's movements, not daring to move an inch, for fear that the slightest mistake would jeopardize her happiness for the rest of her life.

Once urine started flowing from the catheter, indicating that the tip had entered the bladder, the patient in bed 32 finally relaxed and put their head back on the bed.

Lu Renxin continued to insert about 8 centimeters to ensure that the balloon was completely inside the bladder, and then injected the prepared saline solution.

[Congratulations, host, you have successfully inserted an indwelling catheter*1. Treatment value +0.5]

After packing up his things and throwing away the trash, Lu Renxin returned to the duty room, feeling sleepy.

But tonight is destined to be an extraordinary night.

The telephone kept ringing in the duty room, and he kept doing sit-ups in the background noise.
