Intravertebral anesthesia, also known as hemispheric anesthesia, is the injection of local anesthetic drugs into different interspaces within the spinal canal, reversibly blocking and attenuating the corresponding spinal nerve conduction function.
Intravertebral anesthesia has some contraindications, such as coagulation disorders, intravertebral tumors, cervical and lumbar intervertebral disc herniation, local anesthetics previous allergies and other conditions can not be carried out in the intravertebral anesthesia, which will easily lead to poor efficacy, and will cause harm to the body.
Patients with contraindications to intraspinal anesthesia can switch to other anesthesia methods such as general anesthesia or regional block anesthesia to meet the needs of surgery.
Generally speaking, the doctor will explain the precautions of intrathecal anesthesia before the surgery, and the patient must actively cooperate with the treatment, and explain in time if there is any discomfort.
