Whats meant by line of demarcation “in traumatic asphyxia”, and whats its mechanism?
A4:The line of demarcation is the line that separates the compressed area from the area above the compression. Veins are more superficial thus they shut down more readily with pressure. The area above the compression is deprived of its regular venous return, and thus there is stasis and congestion above the level of the compression Q5:In the exam, there was a true/false question asking if Cadaveric spasm is considered a sure sign of drowning. A5:Cadaveric spasm (holding aquatic weeds, mud, sand, and gravel) IN AN IMMERSED cadaver is a sure sign of drowning.
