1 FISIOLOGI PENYEMBUHAN LUKA

2 MOIST WOUND HEALING George D Winter (1962): proved that wounds that were kept moist, healed better than those that were exposed to the air. THE FATHER OF MOIST WOUND HEALING Home WORK : Why MOIST ?

3 J USTIFIKASI 1.Fibrinolisis : fibrin cepat hilang pada suasana lembab oleh netrofil dan sel endotel 2.Angiogenesisi : proses akan lebih terangsang pada suasana lembab 3.Infeksi : lebih rendah dibandingkan suasana kering ( 2.6 % vs 7.1 % ) 4.Percepatan pembentukan sel aktif : invasi netrofi yang diikuti oleh makrophag, monosit dan limfosit ke daerah luka akan berfungsi lebih dini. 5.Pembentukan growth factor : lebih cepat pada suasana lembab * EGF, FGF dan Interleukin1 dikeluarkan oleh makrophag untuk proses angiogenesis dan pembentukan str. Korneum * Platelet-derived Growth Factor (PDGF) dan Transforming Growth Factor-beta (TGF-beta) dibentuk oleh platelet untuk proses proliferasi fibroblast.

7 I NFLAMMATORY S TAGE Tanda : kemerahan, panas, nyeri dan bengkak Last approximately 4 to 5 days Permulaan terjadinya proses penyembuhan luka : aktifitas platelet untuk STOP perdarahan dan triggers the immune response 24 jam pertama saat terjadi perlukaan, neutrophils, monocytes and macrophages mengontrol pertumbuhan bakteri dan membuang jaringan mati ( mempersiapkan dasar luka ) Characteristic red color and warmth is caused by the capillary blood system increasing circulation & laying foundation for epithelial growth

8 P ROLIFERATION S TAGE Begins within 24 hours of the initial injury and may continue for up to 21 days It is characterized by three events: Epithelialization Granulation Collagen synthesis Formation of new capillaries that generate and feed new tissue Granulation tissue is the beefy red tissue that bleeds easily

9 P ROLIFERATION : E PITHELIAZATION Formation of an epithelial layer that seals and protects the wound from bacteria and fluid loss It is essential to have a moist environment to foster growth of this layer It is a very fragile layer that can be easily destroyed with aggressive wound irrigation or cleansing of the involved area

10 P ROLIFERATION : C OLLAGEN S YNTHESIS Creates a support matrix for the new tissue that provides it with its’ strength Oxygen, iron, vitamin C, zinc, magnesium & protein are vital for collagen synthesis This stage is the actual rebuilding and is influenced by the overall patient condition of the wound bed

11 M ATURATION FINAL stage of wound healing Begins around day 21 and may continue for up to 2 years Collagen synthesis continues with eventual closure of the wound and increase in tensile strength Tensile strength reaches only about 80% of pre-injury strength
