Neurogenic shock can be due to a severe damage to the central nervous system such as the brain and the higher levels of the spinal cord especially the cervical and thoracic regions. The mechanism is that once the there is trauma, the sympathetic functions of the body will be disrupted which might lead to the relaxation of the blood vessels, thereby decreasing the blood flow to the entire system. If not promptly managed, neurogenic shock can be life-threatening as continuous insufficiency in blood supply will cause cell death and organ failure.
Approximately 11% of patients with spinal cord injuries meet the criteria for Major Depressive Disorder (MDD). Therefore, in patients with spinal cord injuries who show symptoms of depression, such as suicidal ideation, it is important to screen for major depression and consult for psychological care.
Bombardier et al found % of participants with spinal cord injuries met criteria for MDD. They found MDD was associated with poorer subjective health, lower satisfaction with life, and more difficulty in daily role functioning.
Kishi et al found that both acute and delayed-onset suicidal ideation was strongly associated with the existence of major depression and impaired social functioning in patients with spinal cord injury. They argue that the detection and appropriate treatment of depressive disorders and social isolation may be the most important factor in preventing suicide both during the acute and chronic period following spinal cord injuries.
Lightning injuries occur infrequently, but cause an average of 35 deaths per year in the . Although there are about 8 million lightning strikes per day on earth, few people are struck and/or killed. Lightning is an environmental form of electric shock that may or may not show external burns, but lightning can injure or kill due to cardiac or respiratory arrest. Neurologic injury is common in individuals struck by lightning. Other injuries are due to severe muscle contractions triggered by the electricity. Indirect injuries caused by lightning strikes can occur with trauma from explosive forces (for example, tree sap and fluid being superheated and trees blown apart due to steam pressure generated when lightning heats up tree sap) or from the electrical charge from lightning dissipated through water and/or the earth.
