  Chang Jiawei, who was watching her from the side, gleamed in his eyes, and his eyes were pointed directly at her sharply: This guy, the judgment has a sharp effect? Can anyone who has just entered clinical practice do this?

  Nie Jiamin put his hands in the pockets of his white coat, his head tilted as if his attention was only on Xie Wanying's hands.

   Zhu Huicang stood up, as if he wanted to take a closer look.

  Dai Nanhui, Geng Lingfei and Fan Yunyun were not quite sure what happened.

   Determine the depth of the abscess. If it is relatively shallow, anesthesia is not needed. The doctor gently picks the abscess skin twice with the tip of the needle or the tip of the knife, and the pus can be drained. There is no need for the patient to receive another needle. However, the situation of the child in front of him is more serious, and the family members are given a delayed illness. The infection has come to the fascia, and it will not work without anesthesia.

   It's time for anesthesia, and there is no anesthesiologist accompanying me. However, such minor surgical procedures have never been accompanied by an anesthesiologist. There are few anesthesiologists in the country, and this kind of local anesthesia is very simple. Local anesthesia can be said to be a technical threshold to test the independent operation of the surgeon.

   There are several types of local anesthesia, including topical anesthesia, local infiltration anesthesia, regional block anesthesia, and nerve plexus block anesthesia.

  For example, before a normal gastroscopy, a patient is instructed to swallow a mouthful of anesthetic, and the throat feels numb. This is a surface anesthesia, which mainly acts on the mucous membranes. For minor outpatient surgery, such as common hemorrhoid surgery, the doctor injects a ring of anesthesia around the patient's **** nerve to block the perianal nerve in the area. The plexus block is divided into several parts, such as the upper limb plexus block for orthopedic hand and forearm surgery. This is not performed in an outpatient clinic, but is performed by an anesthesiologist in the operating room, and if it is a child patient, it must be combined with general anesthesia. .

   Compared with adults, children are very uncooperative and move around easily. Only general anesthesia can make children sleep without affecting the doctor's operation. Therefore, as long as it is a relatively large operation, the younger the child, the less local anesthesia is required, and the general anesthesia is generally more.

   Fortunately, the patient is ten years old, and there is no general anesthesia condition at the scene, so you can try it.

After the comprehensive judgment, Xie Wanying made a decisive decision and reached out to the nurse: "Syringe, lidocaine, normal saline."

  Thank you for being so majestic. Fan Yunyun wanted to imitate the idol's actions in her heart.

  Dai Nanhui and Geng Lingfei felt that Xie Wanying was full of courage. It was unbelievable that she was not afraid at all in front of so many people.

   Yao Jie handed her the ampoules that were knocked open with anesthetic and normal saline, and let her inhale the medicine by herself.

  Pull the plunger of the syringe, and firmly insert the needle into the ampoule to inhale the medicine. Others were shocked to see that her hand was as steady as a mountain without the slightest shaking.

   Prepared the local anesthetic by herself, and Xie Wanying pointed the needle around the infected skin of the patient and inserted it.

  The onlookers breathed a little tight.

  Experts know that local infiltration anesthesia is not just anesthesia, but also a probe for later surgery. With this needle down, the depth of the patient's bone can be probed, and the range within the depth of the abscess can be probed. Therefore, local infiltration anesthesia requires a needle to general anesthetize the nerves within the surgical range. Therefore, if the scope of the operation is large, more than one injection is required, and additional anesthesia should be applied in other places around the wound to make general anesthesia in place.
