Question Hey Marcus. A little while back I read a news report about a 19 year old girl who got fatally stabbed by her uncle. The weapon used was some kind of knife. I read that she died from a single stab wound to her gut with a depth of 22cm. I was wondering about these kinds of injuries. How important is the depth of the wound in terms of the likelihood that it would be fatal? Would someone be generally more likely to survive a 20cm stab than a 10cm one for example? Also how important is the location of the injury? So if it was an abdominal stab what would be the best or worst areas in terms of surviving?
Answer Hello Rob,
It's not so much the depth but the placement of the blade. There's a book called "The House of GOD" about a medical resident's experiences. A quote from the book goes "There is no organ in the body that cannot be reached with a one and a half inch needle and a good strong arm". The large vessels of the neck, armpit and groin are within an inch of the surface (maybe even less at points). A 2 inch needle placed through the skin at the xiphoid process and directed up toward the left shoulder is commonly used to drain the sack around the heart of excess fluid. A standard steak knife is sufficiently long enough to reach the large aorta and venicava that lye's along the anterior spine if the victims belly is not unusually large. Just a nick if one of the large vessels is enough to allow bleeding to go uncontrolled leading to death.
