Question

4. While your buddy was trying to get away from the vampire, he fell and was crushed by the weight of the vampire on his leg. Your buddy is initially low on blood volume, but the next day his blood volume is back to normal, but his leg muscle injury causes the leg to swell. The muscle is surrounded by fascia—a type of connective tissue that creates a compartment around the muscle. This situation is called “Compartment Syndrome” since the muscle is essentially locked into a compartment by the fascia. Assume that everything else physiologically is good with your buddy (they gave him whole blood at the ER, so he is back to normal blood values). Which Starling force is impacted by the compartment syndrome? Why? Show your math as to the effects of compartment syndrome in the muscle capillaries. Given your analysis, what needs to be done in the ER to deal with the crush injury? It is Halloween! Your best buddy was chased down by a vampire, and was caught. The vampire fed' on your buddy, but your buddy did not taste very good to the vampire, so the vampire only ate 1.5 L of blood before letting your buddy go. Assume that the vampire saliva did not have any components in it that would interfere with the normal physiological response to hemorrhage Use the table below (describing events related to hemorrhage normal 1 hour after hemorrhage 18 hours post hemorrhage otal blood volume (mL) throcyte volume (mL 5000 2300 2700 4000 1840 2160 4900 1840 3060 Plasma volume (mL) These questions are asking about mechanisms operating to regulate life processes (i.e. the HOW or the WHY events occur). These questions MUST be answered by stating a MECHANISM or PATHWAY. Just saying that something occurs, or that "it goes up" is not a mechanism or pathway. Mechanisms and pathways are the molecular and/or cellular steps involved in the final outcome

Explanation / Answer

Compartment syndrome- Incresed pressure in the compartments leads to pressure on vessels and capillaries thus reducing blood flow the muscles

The starling force affected by the compartment syndrome is decreased local perfusion which is happen in the venous side of the blood vessels.

Starling force is responsible for outward and inward fluid movement at the arteriol and venous side of vessels. So in compartment syndrome more and more pressure is produced thus affecting the hemostasis of this cycle...

So in the compartment syndrome the first step need to do in er is fasciotomy which is cutting of fascia surround the muscle in order to prevent the acute blood loss to the muscles. it is also knows as limb saving surgery.
