Chapter 166 Zhao Heng's New Idea - N-Yag Laser Resection!
"Just try your best."
Zhao Heng thought for a while and said.
Penetrating head injury + brainstem glioma, no doctor in the world can say that he is absolutely sure of the anesthesia for this kind of surgery.
"Maybe some operations in the operation still need your cooperation, junior, this time, I really have to work hard on you."
Liu Ziang said.
Zhao Heng has a very high level of attainment in brain surgery, which Zhao Heng showed in the previous operation.
But this time, in addition to safely removing the steel bars inserted into the head and repairing the damaged tissue, the operation of removing the brain stem glioblastoma is also required. In Liu Zi'ang's view, only Zhao Heng has this level of operation to cooperate with him. up.
The most important thing is that for this patient, if he does not take this opportunity to resect the brainstem tumor, even if the steel bar inserted into the head is successfully removed, the patient survived this operation, and along with the brain For the development of stem tumors, the patient's time will not exceed three months at most.
"fine."
Zhao Heng said indifferently.
If you want to be easy, you will not choose the profession of a doctor.
after an hour.
operating room.
For this operation, Zhao Heng was in charge of anesthesia, Tian Zhen was the equipment nurse, Sun Li was the roving nurse, and Liu Ziang led two residents to perform the operation together.
Beside the workbench, Tian Zhen was preparing for the operation, and Liu Ziang was watching the CT scan of the brain.
On the other hand, Zhao Heng and Sun Li are undergoing preoperative anesthesia.
"Doctor Zhao, what is the intravenous anesthetic used this time?"
Sun Li looked at Zhao Heng, who was in deep thought, and asked him.
Head trauma is not uncommon in brain surgery, but this is the first time that even Sun Li, who has participated in many brain surgeries, has seen such an injury directly pierced through the head by a steel bar.
Therefore, she knows better what level of anesthesia is required to be in charge of this operation.
"Propofol and remifentanil."
Zhao Heng thought for a while and said.
Propofol, a new type of anesthetic known as "cross-century", has the advantages of fast onset of action, rapid metabolism, and continuous use without accumulation. It is most suitable for target-controlled infusion (TCI) for this patient.
Remifentanil is the latest type of pure μ receptor agonist, which also has the advantages of fast clearance and low side effects after use.
The condition of this patient is extremely unstable. For the anesthesia of this patient, it is necessary to choose an anesthesia method that least interferes with the patient's physiological functions.
"Ok."
Sun Li nodded. The two anesthetics that Zhao Heng mentioned were basically new types.
Ordinary anesthesiologists are still stuck in the use of anesthetic drugs in the past. They are generally not sure about using new anesthetic drugs such as propofol and remifentanil, let alone using them on patients with such complicated conditions.
Next, Sun Li quickly prepared the intravenous anesthesia, and as the intravenous anesthesia was injected into the blood vessel, the patient entered a state of deep anesthesia.
However, Zhao Heng still held it tightly in his heart.
10 minute later.
Zhao Heng looked at the blood pressure and heart rate on the vital monitor, and said to Liu Ziang, "Senior, the operation can begin."
"okay."
Liu Ziang nodded.
With Zhao Heng around, he still felt at ease.
This feeling is very strange. As a master of brain surgery, when he is always around, others will feel at ease.
But now, the strong technical support provided by Zhao Hengneng gave him such a sense of peace of mind.
Liu Ziang regained his composure, and started the operation with two residents. Although he is a master in brain surgery, this operation is also very difficult for him.
The steel bar with burrs is now staying in the patient's skull. It is imperative to take the steel bar out of the patient's skull as soon as possible and minimize the damage to the patient's brain tissue.
In this process, every step of the operation must be done with care and caution.
This requires extreme concentration and extreme stability of the hands.
To put it bluntly, in this operation, the two residents brought by Liu Ziang can only do the laying-in work. The most critical part of the fine operation must be done by Liu Ziang himself.
Time passed minute by minute. Although it was difficult, in Liu Ziang's hands, after two hours, the steel bar inserted into the skull was completely removed.
Next, the most difficult part, is to remove the glioblastoma on the brainstem.
This operation can almost be said to be one of the most difficult operations in brain surgery.
On the one hand, the brainstem is the center that controls the heartbeat and breathing of the human body. Once the brainstem is damaged during the operation, the patient's breathing and heartbeat will stop immediately. Basically, if the operation goes wrong, the patient will most likely die immediately.
This can be said to be life and death in an instant.
On the other hand, the process of removing glioblastoma is extremely difficult.
Visually speaking, the glioblastoma that infiltrates and grows in the brain tissue is like cauliflower growing in tofu. It is the most difficult part to completely remove the cauliflower bit by bit without damaging the tofu at all. .
Next, Tian Zhen has to prepare the equipment for brainstem tumor resection, which will take some time.
On the other hand, Liu Ziang sat down next to Zhao Heng to rest, discussing the details of the next surgery.
"Student, what do you think about the next operation?"
Sitting next to Zhao Heng, Liu Ziang asked.
Generally speaking, only Zhao Heng can get his approval if someone asks about him, so he still values Zhao Heng's opinion very much.
"The patient's condition is very unstable, the operation must be done as soon as possible, and the routine peeling is too slow."
Zhao Heng thought for a while and said.
"What do you mean?"
Hearing Zhao Heng's words, Liu Zi'ang nodded immediately. This was also what he was worried about. The conventional brain tumor resection would take too long and could not be used on this patient at all.
The operation must be completed as soon as possible to avoid further accidents. Once the operation time is prolonged, in this patient's condition, the probability of complications, such as breathing and heartbeat arrest, is almost [-]%.
"We can apply the resection technique for soft tumors, using N-Yag laser to burn the tumor tissue and then aspirate it."
Zhao Heng slowly expressed his thoughts.
This idea is a method summed up by combining his brain surgery experience from Liu Ziang's fusion and some other surgical experience.
"N-Yag laser? This equipment does exist, but this method has never been used to remove brainstem tumors before."
Hearing Zhao Heng's words, Liu Zi'ang's eyes lit up instantly, he fell into thought, and murmured.
This YAG laser has the characteristics of high gain, low threshold, high quantum effect, and small thermal effect. It has the advantages of small trauma and good healing when used in medicine.
"Although YAG lasers are generally used in departments such as skin care, cosmetology, and ophthalmology, I think it is more suitable for resection of soft brainstem gliomas."
Zhao Heng said again.
"Well, it is indeed. Junior, you have given me another surprise."
Hearing Zhao Heng's words, Liu Ziang nodded repeatedly.
The laser ablation method proposed by Zhao Heng was something that even he had never thought of.
But thinking about it this way, laser resection not only causes less damage, but also greatly shortens the operation time.
It's just that no one had thought of applying lasers to such a critical location as the brainstem before.
