The human body is a precision instrument assembled by nature. No surgery on any part of it should be taken lightly.

Blood vessels and nerves in the superficial fascia can be divided into anterior lateral and posterior groups according to their location.

The anterior group included trochord artery vein and trochord nerves 2 cm from the midline, and supraorbital artery vein and supraorbital nerves 2.5 cm from the midline. The superior trochord artery and supraorbital artery are branches of the ophthalmic artery. If it is connected back, the ophthalmic artery must be escorted, and the location is the frontal part.

The lateral group includes two groups on the anterior and posterior ear. The anterior ear group has superficial temporal artery vein and aortic temporal nerve, and the posterior ear group has posterior ear nerve and posterior ear cervical plexus nerve of the posterior ear nerve and occipital nerve.

The above contents were what Geng, who was studying hard, saw when he opened the neurosurgery notes recorded in his pocket and reviewed them on-site. For this reason, he looked at Pan, who was assigned to Ichisuke, with concern.

You know, Song Mao had already been eyeing the few of them, especially those who were ready to attack and abuse at any time.

The nerves and blood vessels on the scalp are so rich that it is not easy to remember them one by one.

Let’s look at the nerve vessels in the posterior group. The posterior group has occipital artery, vein and occipital auricular nerve. The occipital artery is the posterior branch of the second cervical nerve. It passes through the deep muscles of the neck and then goes to the plane of the upper neck line, and passes through the trapezoidal aponeurosis to the cranial aponeurosis two centimeters from the midline. The accompanying occipital artery vein is occipital artery vein.

If the arteriovenous veins on the top of the cranial apex are spread widely, it ensures that the scalp will not be necrotic easily when the large pieces are broken. The nerves on the top of the cranial apex also overlap and densely, so it is not enough to often use one medicine when doing a relatively large-scale local anesthesia on the scalp, so it is necessary to apply multiple needles extensively.

"You can check it out first." Song Xuelin said to his assistant.

As expected, Geng looked at Pan with a anxious look on his face.

Student Pan, who received the instructions, focused on finding the anatomical position.

A large group of teachers around me watched, not only neurosurgery, but also invisibly a lot of pressure.

I don’t know if it was because of the fact that Student Xie was deliberately helping him relieve stress and talking to the monitor about the patient’s electrocardiogram.

"I think it's more like a second-degree type II atrioventricular block," Xie Wanying analyzed, "The PR interval is long, and there are signs of QRS wave dropping in the middle."

Second-degree atrioventricular block is that some conduction is interrupted during the transmission of the atrium to the ventricle. Because some causes are interrupted, the atrium cannot conduct itself to the ventricle. The QRS wave representing ventricular electrical activity is delayed or dropped, while the p wave is relatively normal on the electrocardiogram curve.

Due to this situation, although the patient is on the verge of shock, his heart rate is not fast and slow, which has attracted the attention of doctors in the local hospital. It is correct to notify the cardiologists in the National Association of China to participate in emergency treatment.

Clinically, second-degree atrioventricular blocks are divided into type I and type II. The former is more common, and both are patients with myocardial infarction. Considering that this female patient is not young, she is in her forties and is inevitably tired after working for a long time. It is not ruled out that it is a sudden faint caused by heart factors, which leads to an unexpected tragedy. After the neurosurgery is completed, it is necessary to carefully perform cardiac examinations on the patient.

"Hmm--" Fu Xinheng had no big dissent after listening to her diagnostic analysis, and then asked her about her next diagnosis and treatment plan, "What do you think you need to deal with now?"
