Traumatic Gun shot wounds from 7.62mm and effect on lower limbs Essay
Traumatic Gun shot wounds from 7.62mm and effect on lower limbs - Essay Example It is then imperative that modalities in medicine be upgraded to combat manââ¬â¢s health opponents. Researches and studies in science have been very useful and relevant in conquering the battle against illnesses which commends the utilization of a wide range of treatment modalities from simple techniques to intricate equipments. Accidents or illnesses involving blood loss may lead to hemorrhagic shock which is life threatening. Although our body has its own mechanics in counteracting instability, a profound and in many cases, chronic illnesses may lead to exhaustion of the bodyââ¬â¢s system thus failing its purpose in maintaining equilibrium. Wound repair is the attempt of the tissues that are damaged to return to their normal activity and architectural and mechanical integrity after the damage. More often than not perfect restoration of fluid loss, prevention of infection, reinstating previously normal flow of blood and the lymphatic system is not achieved due to the necessi ty and rush to go back to and perform its function especially if the injury is severe and diffuse. Regeneration on the other hand refers to flawless restoration of the previous tissue structure without formation of a scar. While regeneration is the aim of wound healing, it only happens during embryonic growth and development and in lower forms of organisms. A fundamental concept in wound healing in humans is that all injured tissues pass with in the similar sequence of processes which are assigned into definite phases. Yet, these activities in each stage may coincide within the same time in a single wound. Every wound assumes the fundamental phase of wound repair. Acute wounds undergo the organized and well-timed process of repairing in order to attain long lasting structural and functional restoration of the tissue. Meanwhile, chronic wounds do not undergo to re-establishment of its functional integrity rather restoration is delayed in the inflammatory phase due to several causes a nd do not advance to the last phase (Townsend, et al., 2007). Hemostasis is defined as blood loss from a damaged blood vessel. In the setting of a severely injured or ruptured vessel the process of hemostasis can be accomplished by various methods: constriction of the vessels affected, organization of platelets to form a plug, creation of a blood clot with the virtue of blood coagulation, and eventually, production of fibrous tissue within the to permanently seal the gap in the blood vessel (Guyton & Hall, 2006). Each of the mechanics of hemostasis act in sequence but are also interconnected so as to promote multiple reinforcement to the area of impairment. Instantly after a trauma to a vessel, the injury to the wall of the blood vessel results to contraction of the wall which is in turn caused by reflexes, local spasms, and local platelet factors especially the thromboxane A2 which is a potent vasoconstrictor. In effect, the blood flow from this vessel is decreased. The contraction can last from a few several minutes to few hours in which the next step of forming a platelet plug can be initiated. If the injury to the vessel is very minute, the cut is usually blocked by a platelet plug instead of a blood clot. These little cuts in the blood vessels happen daily. The next hemostatic mechanism is the formation of the blood clot which starts to form within the first 15 to 20 seconds after the trauma, if the injury to th
