The length of lumbar nerve block maintenance time is related to the patient’s sensitivity to the drug, and the maintenance time of lumbar nerve block for most patients is 14 to 21 days.
Lumbar nerve block is usually chosen to be injected at the nerve root near the intervertebral foramen to relieve nerve root edema and achieve analgesia through the action of local anesthetics, nutritive nerve drugs or glucocorticoids and other drugs.
Most patients can maintain 14 to 21 days without pain and swelling in the lower back and legs after one lumbar nerve block, and the maintenance time may be extended or shortened according to the patient’s sensitivity to drugs.
Patients suffering from lumbar spine disease should go to the hospital in time and choose the appropriate treatment method under the doctor’s advice.
