Patient Gender: Female All symptoms: Spinal pain after caesarean section, covering an area of ??the spine. It feels like a stabbing. It takes a long time to recover, and I can't even sit on a chair. The pain lasted for half a year and then suddenly improved. Time and cause of onset: Caused by anesthesia during caesarean section in 2005. At that time, I was afraid of pain during the surgery. The doctor suggested wearing an anesthesia stick. The surgery was successful and the recovery was very good. Only the back spine where the anesthesia stick was replaced was very inconvenient. I developed pain four days later. Finally, I called the anesthesiologist to remove it. At that time, the anesthesia stick was removed. There was only a thin plastic tube with a piece of gauze on it, and there was no needle. I was wondering how the plastic tube was inserted into my back. Could it be that the needle was so small that it entered my body, causing pain? Now I Sometimes there is a tingling sensation somewhere on my body, and I'm scared. Treatment situation: I asked the hospital where I had the surgery and they said it was normal, but I felt they didn’t tell me the truth. I want help: Can any professional doctor please tell me and give me some advice? Doctor 1: This is a common reaction after anesthesia. It has nothing to do with analgesia (the anesthesia stick you mentioned). It is usually punctured with a specific needle. After inserting it, put the catheter through the needle, and then pull the needle out, so what you see is the tube, not the needle. Go to the pain department to have a look. Doctor 2: Hello, the anesthesia rod you mentioned is placed during spinal anesthesia. The tube is used for additional anesthesia during the operation and postoperative pain relief. It has no effect on you. This is really normal. You don't need to worry too much. Doctor 3: Mainly includes general anesthesia, local anesthesia and compound anesthesia. According to the way the anesthetic enters the human body, it is divided into inhalation anesthesia, intravenous anesthesia and basic anesthesia. Basic anesthesia is the intramuscular injection of certain general anesthetics (commonly used sodium thiopental, ketamine) to put the patient into a sleep state, and then perform anesthesia surgery. Local anesthesia uses local anesthetics such as procaine, lidocaine, etc. to temporarily lose feeling in a certain part of the body. Commonly used methods include neuraxial anesthesia (block), nerve block, regional block, local infiltration anesthesia, and topical anesthesia. Spinal anesthesia is the injection of local anesthetic into the spinal canal through spinal puncture. Injection into the subarachnoid space is called subarachnoid block or spinal anesthesia, and injection into the epidural space is called epidural anesthesia. cavity block. Nerve block is to inject local anesthetic into a certain nerve trunk (plexus) in the body to cause pain conduction block in the area controlled by it. Commonly used nerve blocks include cervical plexus block and brachial plexus block. Regional block is to inject local anesthetic around the surgical site to block the nerve endings in the surgical area to achieve the purpose of anesthesia. Local infiltration anesthesia is to inject local anesthetic directly into the surgical site and evenly distribute it into all layers of tissue throughout the surgical area to block the conduction of pain. It is a commonly used anesthesia method for minor clinical operations. Topical anesthesia involves spraying or applying highly permeable local anesthetics to mucous membranes, conjunctiva and other surfaces to produce anesthesia. Compound anesthesia is the simultaneous or sequential application of two or more anesthetics, auxiliary drugs (such as analgesics, tranquilizers, etc.) or anesthetic methods in anesthesia, so that they complement each other to enhance the anesthetic effect and protect the patient. safety, and to meet the special requirements of certain surgeries. The anesthetic method should be selected based on the condition and surgical needs, as well as the indications and contraindications of the anesthetic method.
