Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 2988 [2988] Stop by

  The human body is a precision instrument assembled by nature. It is true that any part of the operation should not be taken lightly.

   The blood vessels and nerves within the superficial fascia can be divided into anterolateral and posterior groups according to their location.

The   anterior group included the trochlear artery and vein and the trochlear nerve 2 cm from the midline, and the supraorbital artery and vein and the supraorbital nerve 2.5 cm from the midline. The supratrochlear artery and the supraorbital artery are the branches of the ophthalmic artery. If they are connected back, the ophthalmic artery will be connected to the forehead.

  The lateral group includes the two groups in front of the ear and behind the ear. The preauricular group had superficial temporal artery and vein and auricular temporal nerve, and the postauricular group had the posterior auricular artery and vein and the posterior branch of the greater auricular nerve and the lesser occipital nerve of the posterior auricular branch of the facial nerve.

   The above content is what Geng, a serious student, found when he took out the simple neurosurgery notes in his pocket and opened it to review it on the spot. For this reason, he looked worriedly at Pan, who was assigned as a helper.

   You must know that Song Mao had already been targeting them, especially those who were ready to abuse classmate Pan at any time.

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

  Look at the neurovascular in the posterior group. The posterior group has the occipital artery, vein and greater occipital nerve. The greater occipital nerve is the posterior branch of the second cervical nerve. It passes through the deep nuchal muscles to the plane of the greater superior nuchal line, and traverses the trapezius aponeurosis two centimeters from the midline to the cranial parietal region. Accompanying the occipital artery and vein.

  The arteries and veins of the cranial top have many anastomosis points, such as wide cast nets, to ensure that the scalp is not easily necrotic when a large piece is broken. The nerves on the top of the skull are also densely overlapped with each other, so it is often not enough to use one medicine for a relatively large-scale local anesthesia of the scalp, and multiple needles are widely used.

   "You look at each other first." Song Xuelin said to his assistant.

   Sure enough. Classmate Geng looked at Classmate Pan anxiously.

  Pan, who was instructed, focused on finding the anatomical position.

   A large group of teachers are watching, not only neurosurgery, but also a lot of pressure.

   I wonder if Xie was intentionally helping him decompress, and he was discussing the patient's ECG line with someone outside his heart and mind on the monitor.

   "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 waves falling in the middle."

Second-degree atrioventricular block means that part of the conduction from the atrium to the ventricle is interrupted due to some causes, resulting in the failure of the atrial conduction to reach the ventricle. The QRS wave representing the electrical activity of the ventricle is delayed or dropped, and the p wave is in the ECG. The curve is relatively normal.

  Because of this situation, although this patient was on the verge of shock, the heart rate was not fast but slow, which attracted the attention of the doctors in the local hospital, and specially notified the cardiologists of the National Association that it was correct to participate in the emergency consultation.

  Clinically, second-degree atrioventricular block is divided into type I and type II. The former is more common, and both of them can be seen in patients with myocardial infarction. Considering that the female patient is not young, she is in her 40s, and she is inevitably fatigued after working for a long time. After the neurosurgery is completed, the next step is to carefully examine the patient's heart.

   "Well—" Fu Xinheng had no major disagreement after listening to her diagnosis and analysis, and then asked her the next diagnosis and treatment plan, "What do you think needs to be done now?"

   "I think it is possible to take a preventive blood test to check the three items of serum potassium and myocardial infarction." Xie Wanying replied.
