Sometimes your doing research into one thing and KAPOW there's something
else and ya juss gotsta share!
<<Only flash floods and river floods cause more weather-related deaths. But
according to Dr. Elisabeth Gourbière of the Electricité de France, Service
des Etudes Médicales, only 20 percent of lightning victims are immediately
Lightning injuries are not the same as electrical shocks. For one thing, the
contact voltage of a typical industrial electrical shock is 20 to 63
kilovolts, while a lightning strike delivers about 300 kilovolts.
Industrial shocks rarely last longer than half a second (500 milliseconds)
because a circuit breaker opens or the person is thrown far from the live
conductor. Lightning strikes have an even shorter duration, only lasting up
to a few milliseconds. Most of the current from a lightning strike passes
over the surface of the body in a process called "external flashover."
Both industrial shocks and lightning strikes result in deep burns at point
of contact - for industry the points of contact are usually on the upper
limbs, hands and wrists, while for lightning they are mostly on the head,
neck and shoulders. Industrial shock victims sometimes exhibit deep tissue
destruction along the entire current path, while lightning victims? burns
seem to center at the entry and exit points. Both industrial shock and
lightning victims may be injured from falling down or being thrown, and the
leading cause of immediate death for both is cardiac or cardiopulmonary
If you survive a shock, you still have to deal with the consequences of the
electrical burns. Industrial shock burns can lead to kidney failure,
infection, muscle and tissue damage, or amputation.
Most Typical Disorders Associated with Lightning Strikes
(from "Lightning Injuries to Humans in France" by Dr. Elisabeth Gourbière of
the Electricité de France, Service des Etudes Médicales)
Lightning deaths (~20%)
-Inhibition of brainstem respiratory centers
-Multi-system failure (delayed death)
-Arrhythmias - Arterial pressure changes
-Myocardial damages (infarction)
-Pulmonary edema - Respiratory distress syndrome
-Loss of consciousness/coma
-Numbness/Weakness in limbs/Partial or complete (but temporary) paralysis
-Spinal cord injury/Parkinsonism
-Sleep and memory disorders/Concentration
disturbances/Irritability/Depression/Various other disturbances such as
headaches, tiring easily, lightning storm phobia, etc.
-Post traumatic Stress Disorder
Burns and Cutaneous marking
-Small, deep entry/exit points (typical)
-Contact, metal chain heating (typical)
-Lichtenberg figures (arborescent, fern-like markings):pathognomonic(on
trunk, arms, shoulders)
-Exploded off, torn off, shredded, singed?
Blunt traumas (explosion)
-Contusion, internal hemorrhage (brain, lungs, liver, intestine?)
-(rarely) Fractures (skull, cervical spinal column, extremities?)
Auditory and ocular injuries
-Tympanic membrane ruptured (typical)
-Transient blindness/Photophobia-Conjunctivitis - Corneal damage
-Retinal abnormalities (macular hole) - optic neuritis
"Lightning injuries are varied and take many different forms. The most
dangerous (and possibly fatal) immediate complications are cardiovascular
and neurologic. It must be kept in mind that only immediate and effective
cardiorespiratory resuscitation (started by rescuers), followed as soon as
possible by emergency medical treatment, can save victims who are in
cardiopulmonary arrest, or avert the serious consequences of cerebral
hypoxia. Some victims remain in a coma despite intensive resuscitation and
die of secondary causes including hemorrhages and multiple lesions
(encephalic, cardiac, pulmonary, intra-abdominal)."
Just thought someone would care.
