When you have anesthesia for childbirth, it is normal to feel a cold sensation as the medication enters the spine. If you use a pain pump and inject the medication intermittently, you may continue to feel a cold sensation in the spine. If the anesthesia has already been given and you still experience a cold sensation in your spine, it may be abnormal. When anesthesia is given for the birth of a child, epidural anesthesia is given from the lumbar spine. It is the use of a puncture needle to inject local anesthetic drugs next to the spinal cord to anesthetize the corresponding spinal nerve roots, causing loss of sensation in the area innervated by the nerve roots to achieve the anesthetic effect. When the drug is used, the liquid will be injected into the spinal column, so the mother will have a feeling of coldness in the spine. However, this sensation is due to the temperature of the medication and is usually not experienced after anesthesia. If you still have a cold feeling in the spine after anesthesia, you can consider that it may be due to the lack of warmth or abnormal nerve sensation, you can temporarily observe and take good warming measures, if the symptoms do not get better, or even aggravate, or other uncomfortable symptoms, you need to consult a doctor for treatment in a timely manner.
