After suitable exploration purchase minocycline 50 mg visa, in which the underlying structures are repaired discount minocycline 50 mg otc, these wounds may be closed by primary suture if the wound is explored within 6 hours of its occurrence order online minocycline. Within this period all damaged tendons, nerves and major blood vessels should be repaired. The wounds usually have jagged edges with certain lacerated and devitalized structures inside the wound. Thorough debridement of these wounds is required if received within 6 hours of injury. Repair of tendons and nerves is not recommended at the time of initial surgery due to risk of infection and should wait for 4 to 6 weeks for complete healing of the wound and these repairs are done as a secondary procedure after healing. Penetrating wounds are almost similar to incised wounds, except that its depth is more. The wound should be explored layer by layer, followed by primary suturing if it has come within 6 hours of injury. When the oedema and tension have subsided and the tissues within the wounds are viable, delayed primary suture should be performed. Although all wounds heal by the same basic processes, yet their application is different in closed wounds and open wounds. Platelets become adherent and with clotting factors form a haemostatic plug to stop bleeding from the small vessels. Histamine is considered to be the primary mediator of inflammatory vascular responses. Histamine produces local vasodilatation and increases permeability of small vessels. However the action of histamine is short lasting and local sources are depleted rapidly. Kallikrein, an enzyme found in plasma and in granulocytes, releases bradykinin and kallidin. These prostaglandins seem to be the final mediators of acute inflammation and may play a chemotactic role for white cells and fibroblasts. Aspirin and indomethacin are potent inhibitors of prostaglandin biosynthesis and the antiinflammatory action of these drugs actually result from their effects on prostaglandin metabolism. In the early stages of inflammation, actively motile white cells migrate into the wound and start engulfing and removing cellular debris and injured tissue fragments. Leukotaxine, a peptide formed in damaged tissues by the enzymatic destruction of albumin, is thought to be the chemotactic agent — attracting leucocytes into the wound. As the transient phase of white cell migration ends, the granulocytes with shorter life die and release acid hydrolases into the local environment. As the granulocytes are dying, the proportion of monocytes increases significantly and these monocytes continue their scavenging activity for weeks. It has been found out experimentally that wound healing may proceed normally in the absence of granulocytes and lymphocytes, but monocyte must be present to create normal fibroblasts production. Only recently however, the mechanisms responsible for K)ound contraction have been investigated extensively. This wound contraction does not begin immediately and that about 3 to 4 days elapse before movement of the edges become measurable. After this period, there is a period of rapid contraction, which is completed by the 14th day. The magnitude of contraction varies with the species of animal and with the shape, size and site of the wound. So wound contraction is limited in these places, whereas in cervical region or face of old people wound contraction may be more and effective due to lax skin around. When loss of skin occurs over an area such as the malleolar surface of the lower leg and ankle, wound contraction simply cannot occur because there is not enough extra skin around the defect. The first step in studying the mechanism of wound contraction is to try to define precisely where the fundamental process is located. It should be determined whether a centripetal movement occurs because an energy or power source located outside the defect is pushing the skin edges inwards or whether a centrally located power source is pulling the skin edges to the centre of the defect. Removal of fluid by drying has been suggested as a cause of diminution in the size of wound. But this has not been substantiated, as water content of central wound tissue at the beginning of wound contraction has not changed significantly as at the end of contraction. Contraction of collagen has also been incriminated as the cause of wound contraction. Although collagen increases markedly between the 5th and 8th day of healing, yet the total collagen in the wound falls significantly after this period, so it does not correlate with the period of wound contraction. Moreover the rate of wound contraction is not affected by suppressing collagen synthesis. In scorbutic animals, although granulation tissue is formed, collagen production is inhibited and yet wound contraction proceeds normally. But curiously excision of central granulation tissue did not affect the rate of wound contraction. It was further noticed that although wound contraction was not inhibited by excising the central mass of granulation tissue, it could be stopped decisively by excising a very limited zone of tissue just beneath the advancing dermal edge. This area is the strategic location of cells which appear to constitute the machinery for wound contraction. These cells show characteristics of fibroblasts and smooth muscle cells including a rough endoplasmic reticulum and microfilament bundles similar to smooth muscles. In fact colchicine is presently used in the control of fibrous contractures in human beings. Marginal basal cells lose their firm attachment to the underlying dermis, enlarge and begin to migrate into the wound. The fixed basal cells in a zone near the wound edge undergo rapid mitotic divisions (proliferate) and the daughter cells migrate. After bridging the wound defect, the migrating epithelial cells lose their flattened appearance and become more columnar in shape.
