Spinal shock, also known as spinal cord shock, is a physiological response that occurs immediately after an acute spinal cord injury. It is characterized by complete paralysis, absence of reflexes, and loss of sensation below the level of injury. This condition typically develops within minutes to hours after spinal cord injury and may last from several hours to weeks, depending on the severity of the injury and individual differences.
Its main characteristics include:
1. Temporary loss of reflex activity: During spinal shock, reflex activities below the level of injury, such as sweating, urination, and defecation, cannot occur because the corresponding reflex arcs are temporarily unable to function normally.
2. Decreased skeletal muscle tone: This results from the loss of tonic input from the innervating nerves, leading to reduced muscle tension.
3. Decreased blood pressure: This occurs due to reduced vascular tone, as blood vessels are unable to maintain normal contraction to support blood pressure.
Spinal shock can be triggered by various factors, including trauma, spinal cord inflammation, or spinal cord tumors. In terms of treatment, initial management primarily involves symptomatic drug therapy. Once the patient's condition stabilizes, surgical treatment may be considered based on specific circumstances to restore normal spinal cord function or address the underlying cause of the spinal shock.
