Regional anesthesia (Regional Anesthesia) is one of the anesthetic techniques commonly applied to ensure patient anesthesia during surgery. By using local anesthetic, the anesthesiologist will block sensation and movement in a large area of the patient's body (eg arm, leg...) so that the doctor can surgery while the patient is awake and conversing. Regional anesthesia includes techniques such as spinal anesthesia (also known as subarachnoid block), epidural analgesia, and nerve block.
1. How is spinal anesthesia performed?
Usually, anesthesiologists will examine and evaluate the condition of the spine and determine the position of the vertebrae before giving anesthesia. After disinfecting the anesthetic site, the doctor will numb the area to make the patient painless and use a very small specialized needle to penetrate the tissues and tissues to reach the cerebrospinal fluid and inject a dose of medicine. numb the space in this cerebrospinal fluid. When performing this technique, the patient can be in a lying or sitting position.
Spinal Anesthesia is often applied to orthopedic surgery involving the lower extremities such as bone fusion, knee replacement, hip replacement. Cesarean section or surgery related to urogenital tract very often apply this technique.

2. Why do doctors perform epidural anesthesia?
Epidural Anesthesia is a technique performed similarly to spinal anesthesia. However, the destination of these two methods is different. With the epidural technique, doctors often use a larger needle to access the epidural space (not into the CSF space) and doctors often save a piece of wire (catheter) through it. can continuously infuse local anesthetic for the purpose of pain relief during surgery and after surgery.
Epidural technique is often applied to lower extremity surgeries and especially in pain relief for pregnant women during vaginal birth. For some special surgeries, doctors sometimes combine both methods of spinal anesthesia with epidural anesthesia to increase the effectiveness of pain relief during and after surgery as well as minimize side effects. of these two methods.

3. When will the doctors numb the nerve trunk?
Nerve block is a technique that uses anesthetic drugs to block a specific nerve that supplies a certain area, for example, to numb the femoral nerve or to numb the nerve plexus. arm . With this technique, it is suitable for surgery in the extremities, especially the upper limbs, such as surgery to combine bones in the arm or treat soft wounds.
Usually, with this technique, doctors will use an ultrasound machine and/or a nerve stimulator to accurately determine the location of the nerve that controls the area to be operated on to ensure an effective anesthesia.
Vinmec International General Hospital is one of the hospitals that strictly applies safe surgical anesthesia practice standards according to international guidelines. With a team of experienced anesthesiologists and nurses, along with modern equipment such as nerve detectors, ultrasound machines, Karl Storz difficult airway control system, anesthesia monitoring system GE's comprehensive AoA (Adequate of Anesthesia) including monitoring of anesthesia, pain and muscle relaxation will deliver high quality and safety, helping patients to have adequate anesthesia, not awake, no residual relaxant muscle after surgery. Vinmec Health System is also proud to be the first hospital in Vietnam to sign with the World Anesthesiology Association (WFSA) towards the goal of becoming the safest hospital for surgical anesthesia in Southeast Asia.
