Spondylolisthesis is a pathological displacement or dislocation of one vertebra over another, causing deformity and spinal instability, with a subsequent decrease in space for the neurological structures housed inside. The symptoms of this disease are: pain, disability, physical deformity and neurological disorders.
The surgery is indicated when conservative orthopedic treatment or rehabilitation are insufficient to relieve pain or prevent neurological injury, or when the patient has a significant physical deformity or functional limitation.
The surgeon accesses from the back, with the patient in the prone position. Neurological release is performed by removing the bony elements that compress the nerve structures. Subsequently, he makes a fusion between two vertebrae with metallic synthetic material (screws, hooks, rods), to reduce pain and provide spinal stabilization.
The anesthetic technique for this type of intervention is the general anesthesia. The anesthesiologist gives hypnotic drugs to suppress consciousness, and opioid analgesics to treat pain associated with surgery, among other drugs. During general anesthesia, normal breathing is inhibited, and it is necessary to place a tube into the airway, and then the patient is connected to artificial ventilation. During the procedure, vital functions, like cardiovascular and respiratory, are monitored by special machines that provide continuous information about them, which also are controlled by the anesthesiologist.
In these procedures, it is rare, but likely, the need for blood transfusion due to intraoperative bleeding.
In the postoperative period, the physician treats the pain with intravenous medication, and watches the presence of hemorrhage and neurological symptoms.
In ASANES we are specialist in the management of the anesthesia required for this type of surgery. We can also put you in touch with leading surgeons.
