  1. 1. INTEGUMENTARY DISORDERS By Habtamu A.(RN, BSc, MSc in Adult Health Nursing, PhD student) HA(MSN) 1
  2. 2. HA(MSN) 2 Anatomy of the skin • The skin consists of 3 layers: –Epidermis- non vascular outermost layer, continuously dividing cells –Dermis- takes the largest portion of the skin and provides strength and structure. It consists of glands (sebaceous, sweat), hair follicle, blood vessels, and nerve endings –Subcutaneous tissue (hypodermis)- the inner most layer . contains major vascular networks, fat, nerves, and lymphatics
  3. 3. HA(MSN) 3
  4. 4. HA(MSN) 4
  5. 5. HA(MSN) 5 Function of the skin • Protection- protection of underlying structures from invasion by bacteria, noxious chemicals and foreign matter. • Sensory perception- transmits pain, touch, pressure, temperature, itching, etc • Fluid balance (excretion)- absorption of fluids and evaporation of excess. • Temperature regulation- produced heat released through skin by radiation, conduction, and convection • Vitamin synthesis- skin exposed to ultra violet light can convert substances necessary for synthesizing vitamin D3 (cholecalciferol). • Aesthetic- provides beautiness and appearance
  6. 6. HA(MSN) 6 Factors influencing skin integrity • Immoblity is the major factor leading to pressure sore development . • The pt who is confined to bed & unable to change position is at greatest risk . • Trauma most likely occur – over the prominent areas – weight bearing areas
  7. 7. HA(MSN) 7 • Prolonged pressure impairs blood flow to tissue & resulfs in ischemia & inferction • The extent of pressure necessary to cause tisue damage depnds on the tolerance of the pt's skin & supporting stuctures .
  8. 8. HA(MSN) 8 • Tolerance to pressurs trauma is influenced by the following factors: – Duration of pressure – Magnitude of pressure – Body position – Friction – Impaired moblity – Malnutrition – Dehy dration
  9. 9. HA(MSN) 9 COMMON DERMATOLOGIC TERMS • Lichenification: distinictive thickening of skin • Crust: dried exudate of body fliuds • Erusion: epithelial deficiet • Ulcer: epithelial deficiet (disruption of deep skin integrity) • Atrophy: an acquired loss of substance • Scar:change in the skin secondery to trumas or inflammation
  10. 10. HA(MSN) 10 Description of skin lesion (primary lession) I. circumscribed , flat , nonpalpable changes in skin color • Macule = small upto 1 cm, eg. petechia • Patch = larger than 1 cm , eg vitilligo
  11. 11. HA(MSN) 11 Description of skin lesion... II. Palpable elevated solid masses – Papule: up to 0.5cm eg. elevated nevus – Plaque: elevated surface > 0.5 cm – Nodule: deeper & firmer than papule => 0.5 -1-2cm eg tumor – Wheal: irregular, superficial area of localized skin edema
  12. 12. HA(MSN) 12 Description of skin lesion... III. Superficial elevation of skin formed by free fluid in a cavity in the skin layer. • Vesicle: up to 0.5 cm => filled c serous fluid,eg herps simplex • Bulla: > 0.5 cm, Filled of serous fluid, eg 2nd degree burn ( blister) • Pustule: filled pus, eg impetiao, acne
  13. 13. HA(MSN) 13 Secondery lesion IV. Loss of skin surface • Erusion => loss of superficial epidermis • Ulcer => deep loss of skin surface => May bleed & scar, eg. sphilic chancre • Fissure => linear creak in the skin eg.A thlet's foot
  14. 14. HA(MSN) 14 Secondery lesion.... On skin surface: • curst = dried residue of serum ,pus or blood, eg Impetigo • Scale = a thin flake of exfoliative epiderms eg.dandruff, Dry skin, Psoriasis
  15. 15. HA(MSN) 15 Vascular skin lesions • a lesion that originated from a blood vessel – Petechia/Purpura – Ecchymosis – venous star
  16. 16. HA(MSN) 16 Skin lesion configuration • Linear- in line • Annular and arciform –circular or arcing • Zosteriform- linear along a nerve route. • Grouped -clustered lesion • Discrete -separate and distinict • Confluent- lesions that run together or join • Generalized- widespread eruption • Localized- lesions on distinct area
  17. 17. HA(MSN) 17 Assessing the skin • Assessment includes a thorough - history taking, -inspection and -palpation of the skin.

  25. 25. HA(MSN) 25 Assessing the general appearance of the skin • The general appearance of the skin is assessed by observing (Inspection) color, skin lesions, and vascularity. • On palpation skin turgor and mobility, possible edema, temperature, moisture, dryness, oiliness, tenderness, and skin texture (rough and smooth).
  26. 26. HA(MSN) 26 Color change: can be hyperpigmentation, hypopigmentation or depigmentation 1. Redness- fever, alcohol intake, local inflammation due to increased blood flow to the skin. 2. Bluish color (cyanosis) - decreased oxygen supply due to chronic heart and lung disease, exposure to cold, and anxiety
  27. 27. HA(MSN) 27 Cont’ed… 3. Yellowish color (jaundice) - increased serum bilirubin concentration due to liver disease or red blood cell haemolysis - Uremia- renal failure 4. Brown-tan- Addison’s disease: cortisol deficiency stimulates increased melanin production - Birth mark, chloasma of pregnancy (face patches), and sun exposure 5. Pale: Albunism- total absence of pigment melanin • Vitiligo- destruction of the melanocytes in circumscribed areas of the skin

  33. 33. HA(MSN) 33 Diagnostics test • Skin biopsy: removal of a piece of skin by shave, punch, or excision technique for a microscopic study of the skin to determine the histology of cells to rule out malignancy and to establish an exact diagnosis. • Patch testing: performed to identify substances to which the patient has developed an allergy. • Potassium hydroxide test (KOH): helps to identify fungal skin infection
  34. 34. HA(MSN) 34 Diagnostics test… • Gram stain and culture with sensitivity test: helps to identify the organism responsible for an underlying infection with the effective drug identification • Slit Skin Smear (SSS): to identify the causative agent of leprosy (mycobacterium leprea)

Eczema/Dermatitis - It is a chronic pruritic inflammatory disorder affecting the epidermis, and dermis commencing in infancy, often persisting throughout child hood but eventually remitting and some times recurring in adult life. • They are a non-infectious inflammation of the skin and it can be acute, sub-acute or chronic.
  39. 39. HA(MSN) 39
  40. 40. HA(MSN) 40 Con’ted…. • Causes – The exact cause is unknown – Imbalance of the immune system with an increase in the immunoglobulin “E” activity and deficient of cell mediated delayed hypersensitivity. • Can be exacerbated by infection, bites, pollen, wool, silk, fur, ointments, detergents, perfume, certain foods, temperature extremes, humidity, sweating and stress

  146. 146. HA(MSN) 146
  147. 147. HA(MSN) 147 Pathophysiology of burn • Tissue destruction results from: - coagulation - protein denaturation, or -ionization of cellular contents. • Disruption of the skin can lead to: - increased fluid loss, -infection, hypothermia, scarring, -compromised immunity, and -changes in function, appearance, and body image. • The depth of the injury depends on: - the temperature of the burning agent and -the duration of contact with the agent.
  148. 148. HA(MSN) 148 Assessment of burn injury depends on: 1. cause and temperature of the burning agent. 2. location 3. duration of contact with the agent
  149. 149. HA(MSN) 149 Classification of burn • Burn injuries are described according to: - the depth of the injury, -extent of body surface area injured, -location and age.. A. By depth 1. First degree burn (superficial burn) • epidermis is involved • Redness and pain on the area • Healing takes place rapidly within a week.
  150. 150. HA(MSN) 150
  151. 151. HA(MSN) 151 CONT… 2. Second degree burn (partial thickness burn) • epidermis and part of the dermis • Blister formation, pain, moist, mottled appearance of skin, and swelling. • Hair follicles and sebaceous glands may be partly destroyed. • Superimposed infection can interfere with healing • Small burns (1-2% BSA) of this type can be treated through self care
  152. 152. HA(MSN) 152
  153. 153. Deep partial thickness HA(MSN) 153
  154. 154. HA(MSN) 154
  155. 155. HA(MSN) 155 Cont’d.. • infection by gram +ve bacteria (staphylococcus, streptococcus) occurs during the first day. • After the third day, gram –ve bacteria (mainly pseudomonas) predominate and can convert a second degree burn to third degree. • Topical therapy with silver sulfadiazines, silver nitrate or antibiotics is essential
  156. 156. HA(MSN) 156 3. Third degree burn (full thickness burn) • The skin, with all of its epithelial structures, hair follicle, sebaceous gland and subcutaneous tissue destroyed. • Dry, pale white, leathery, or charred, broken skin with fat exposed is seen. • Symptoms of shock and haematuria can be present. • Scarring and loss of function is inevitable. • Needs skin graft for healing
  157. 157. HA(MSN) 157
  158. 158. HA(MSN) 158
  159. 159. HA(MSN) 159 Fourth degree burn (as char burn) • May damage bones, tendons, muscles, blood vessels and peripheral nerves. • Necrosis of muscles and bones can happen. *The following factors are considered in determining the depth of burn: – How the injury occurred – Causative agent – Temperature of the burning agent – Duration of contact with the agent – Thickness of the skin
  160. 160. extravasations HA(MSN) 160
  161. 161. HA(MSN) 161 RXs 1. Superficial burn treatment • Skin is intact so there is a low chance of infection. • Topical “exudates” as physical protection can be used. • Dressings or films that are self adhesive, water proof and semi-permeable. • Skin protectants • Cold compresses, external anesthetics, topical corticosteroids and oral pain relievers.
  162. 162. HA(MSN) 162 2. Superficial partial thickness burn • Unbroken skin Do not disturb blisters!!! They are protective of the skin below the blister. • If broken/debrided: May become infected so cleanse 1-2x’s/day to remove dead skin. Do not pull on skin! • Cleanse with bland soaps or surfactants and water 1-2xs/day • First aid antiseptics or antibiotics sufficient • Dressing and skin protectant should be used
  163. 163. HA(MSN) 163 B. By extent • TBSA -Rule of nine, - Lund and Browder method, and - Palm method. 1. Estimate of body surface area using rule of nine • It assigns percentages in multiples of nine to major body surfaces • It is the most common, simple, and quick method
  164. 164. HA(MSN) 164 Adult 9% Infant (child) 18% • Head • Abdomen and Thorax - Front - Back • Genitalia • Hands - Right - Left • Leg -Right -Left Total 18% 18% 1% 18% 18% - 9% 9% 9% 9% 18% 18% 100% 14% 14% 100%

  166. 166. HA(MSN) 166
  167. 167. HA(MSN) 167 2. Estimate of body surface area using the Lund and Browder method • Is the more precise method of estimating the extent of burn, because it recognizes the various anatomic parts, especially the head and legs • Head----------------------- • Neck----------------------- • Anterior trunk---------- • Posterior trunk--------- • Right buttock------------ • Left buttock-------------- 7% 2% 13% 13% 2 ½ % 2 ½ %
  168. 168. • Genitalia------------------ 1% 4% 4% 3% 3% 2 ½ % 2 ½% 9 ½% 9 ½% 7% 7% 3 ½% 3 ½% 100% • Right upper arm--------- • Left upper arm----------- • Right lower arm---------- • Left lower arm------------ • Right hand----------------- • Left hand------------------- • Right thigh---------------- • Left thigh------------------ • Right leg------------------- • Left leg--------------------- • Right foot----------------- • Left foot------------------- HA(MSN) 168
  169. 169. HA(MSN) 169 3. Palm method • Used in patients with scattered burns • The size of the patient’s palm is approximately 1% of TBSA • In general an adult who suffered burns of 25% and an infant (child) of 15% wherever the location requires Hospitalization
  170. 170. HA(MSN) 170 C. By location • Burns of the -face, -neck and -circumferential burns of the chest may inhibit respiration • Burns of the hands, feet, joints, and eyes are of concern because they make self care impossible and jeopardize later function • Hands and feet are difficult to manage medically because of superficial vascular and nerve supply systems
  171. 171. HA(MSN) 171 Cont… • The ears and nose, composed mainly of cartilage, are susceptible to infection because of poor blood supply to the cartilage • Burns of the buttock or genitalia are susceptible to infection • circumferential burns of the extremities can cause circulatory compromise distal to the burn with subsequent neurologic impairment of the affected extremity
  172. 172. HA(MSN) 172 D. By age • an infant is less able to cope with burn injuries because of: - an immature immune system and - generally poor host defense mechanisms, • The older adult heals more slowly and has more difficulty with rehabilitation than a child or younger adult • Infection of the burn wound and pneumonia are common complications in the older patient
  173. 173. HA(MSN) 173 Fluid type and fluid replacement formulas for burn patients Fluids can be: • Colloids are whole blood, plasma, plasma expanders, and dextran, etc • Crystalloid (Electrolytes) are sodium chloride, ringers lactate, etc Fluid replacement formulas are: • Consensus formula • Evans formula • Brooke Army formula • Parkland/Baxter formula
  174. 174. HA(MSN) 174 1. Consensus formula (In the first 24 hours)- the most commonly used method 2-4ml X kg X % TBSA burned for 24 hours • E.g.: Ato Chane, 38 years old factory worker, 60kg body weight, sustained a burn injury with a 30% body surface burn came to surgical emergency OPD where you are working. • How are you going to calculate the fluid to be replaced for Ato Chane? – Using the Consensus formula – 2ml X 60kg X 30%=3600ml/24 hours
  175. 175. HA(MSN) 175 Plan of fluid administration • Half of the calculated fluid in the above case 1800ml should be given over the first 8 hours and the remaining half that is 1800ml over the next 16 hours. For example • Our casualty has a burn to his legs approximating 18% of body surface: 18 • He weighs approximately 100 Kilograms: 100 • Therefore 100 x 4 = 400, 400 x 18 = 7200 • 7200 CCs of fluid are needed.
  176. 176. HA(MSN) 176 cont’d • Standard IV drip sets for Prehospital cases are usually called Macrodrip sets...they deliver 1ml Q 10 drop, 1ML= 1CC • In order to deliver 3600 CCs of fluid in eight hours we would set the drip rate at 75 drops per minute, or 7.5 CCs per minute. • 7.5 CCs x 480 minutes (8 hours) = 3600 CCs or 3.6 Litres (1000 CCs per Litre)
  177. 177. HA(MSN) 177 2. Evans formula • Colloids- 1ml X Kg X % TBSA burned •Electrolyte(normal saline)- 1ml X Kg X % TBSA burned Plan of fluid administration • Day 1: Half to be given in first 8 hours; remaining half over the next 16 hours • Day 2: Half of previous day’s colloids and electrolytes
  178. 178. HA(MSN) 178 3. Brooke Army formula • Colloids 0.5 ml X Kg X % TBSA burned • Electrolyte(Ringer’s lactate)- 1.5 ml X Kg X % TBSA burned Plan of fluid administration • Day 1: Half to be given in first 8 hours; remaining half over the next 16 hours • Day 2: Half of colloids; half of electrolytes
  179. 179. HA(MSN) 179 4. Porkland/Baxter formula • Ringer’s lactate- 4 ml X Kg X % TBSA burned Plan of fluid administration • Day 1: Half to be given in first 8 hours; remaining half over the next 16 hours • Day 2: Varies. Colloid is added
  180. 180. HA(MSN) 180 Systemic effects of burn • Metabolic - client is in a hypermetabolic stage • Endocrine – increased catecholamines, ADH, aldosterone, and cortisol increase metabolism – O2 and calorie needs are increased – the body is under stress response catabolism increases calorie requirements may be double or triple the usual amount needed
  181. 181. HA(MSN) 181 Respiratory Major cause of morbidity/ mortality – inhalation injury r/t contact to steam, toxic fumes, or smoke – may be r/t treatmentlarge amount of fluid volume infused may cause edema – increase in alveolar capillary permeability – constriction of chest r/t circumferential burn – injury can occur from edema from irritants which cause edema and blockage of trachea
  182. 182. HA(MSN) 182 Respiratory… – decreased movement of the normal cilia in the trachea may allow foreign bacteria and particles to enter into the lungs – lining of the trachea may slough off and become lodged in the bronchus – damage to the alveoli and the capillary membrane may lead to infection and respiratory failure
  183. 183. HA(MSN) 183 Cardiac • cardiac output is the most effected by the loss of fluid • early the rate increases to compensate for the loss of volume • cardiac output remains decreased in spite of the increase rate – may be decreased for 36 hrs – when fluid is replaced goes back to normal function
  184. 184. HA(MSN) 184 GASTROINTESTIONAL - Effects occur due to the shift of blood volume to vital organs - Epinephrine and NE inhibit gastric motility and decrease blood flow to the GI tract - Decreased periostalis occurs - H+ ion production increases - Develop ulcers (Curling’s ulcer within 24 hours) - Use H2 blockers
  185. 185. HA(MSN) 185 Immune response • Widespread impairment of the immune system • Skin is barrier to invading organisms • Changes in the WBC’s occur, • Susceptibility to infection increases
  186. 186. HA(MSN) 186 Renal response • Blood flow to the kidneys is decreased and renal ischemia occurs • Unless flow is improved renal failure occurs • With full thickness electrical burns myoglobin and hemoglobin are released in the blood and can occlude the renal tubles With adequate diuretics and fluid the problem can be corrected
  187. 187. HA(MSN) 187 • Renal function may be altered as a result of decreased blood volume. – Destruction of RBC at the injury site results in free haemoglobin in the urine. – If muscle damage occurs, myoglobin is released from the muscle cells and excreted by the kidney. – If there is in adequate blood flow through the kidneys, the hemoglobin and myoglobin occlude the renal tubules resulting in acute tubular necrosis and renal failure.
  188. 188. HA(MSN) 188 Etiologies of burn • Many causes cause affects the outcome Dry heat-open flame house fire and explosionsŸ Moist heat=scald older adults most common=spills and splatters Contact burns hot metal/tar/grease (industrial, home and restaurants) usually deep because liquid is extremely hot Chemical injury -occurs in home and industry (drain cleaner, acids used in industry or chemicals in industry ) **Severity depends on the length of contact and amount of tissue exposed
  189. 189. HA(MSN) 189 Management of the patient with a burn injury • Burn care must be planned according to the burn depth, local response, the extent of the injury, and the presence of a systematic response. • Burn care then proceeds through 3 phases
  190. 190. HA(MSN) 190 Emergent/ resuscitative phase • Duration is from onset of injury to completion of fluid resuscitation. • The priorities are  ABC of first aid – Prevention of shock – Prevention of respiratory distress – Detection and treatment of concomitant injuries – Wound assessment and initial care
  191. 191. HA(MSN) 191 Emergent/ resuscitative phase… • The goal of fluid replacement therapy should be out put totals of 30 to 50ml/ hour, in addition systolic blood pressure exceeding 100 mmHg and pulse rate less than 110/minute. • Oral resuscitation can be successful in adults with less than 20% TBSA and children with less than 10% to 15 % TBSA
  192. 192. HA(MSN) 192 2. Acute/ intermediate phase • Duration is from the beginning of diuresis to near completion of wound closure. • The priorities are- wound care and closure –Prevention and treatment of complications, including infection. –Nutritional support
  193. 193. HA(MSN) 193 3. Rehabilitation phase »Duration is from major wound closure to return to individual’s optimal level of physical and psychosocial adjustment. »The priorities are- Prevention of scars and contractures. • Physical, occupational and vocational rehabilitation • Functional and cosmetic reconstruction . • Psycho-social counseling
  194. 194. HA(MSN) 194 Nursing management by using the nursing process 1. Assessment • Vital signs- especially respiration rate and pulse • Respiratory functions • Monitor fluid intake and out put • Urine out put hourly • Maximum requirements of fluid replacement • Body weight • History of allergy
  195. 195. HA(MSN) 195 • Tetanus immunization • Past medical and surgical problems • Current illness and use of medication • Patient with facial burns- eye examination • Depth of the wound • Time of injury • Burn occurrence in closed space • Related trauma • Level of consciousness • Excessive fluid volume loss
  196. 196. HA(MSN) 196 2. Nursing diagnosis 3. Outcome identification 4. Planning 5. Implementation 6. Evaluation Complication of Burn/Most severe ones are: • Air way obstruction • Hypovolemic shock • Secondary infection • Contracture
  197. 197. HA(MSN) 197 Wound I. Based on cleanness • Clean wound- has a discharge that may be fresh blood/ serum. • Septic wound- has discharge like pus, exudates, and dead tissues. II. Based on opening • 1. Closed wound- involves injury to the underlying tissues with out a break to the skin or mucus membrane • 2. Open wound- is a break in the skin or mucus membrane
  198. 198. HA(MSN) 198 Cont’d III. Based on tissue damage 1. Abrasion/Graze/wound – The outer layer/superficial layer of the protective skin is scrapped off 2. Incised wound/cut/ – When body tissue is cut by a sharp edged material 3. Lacerated wound • It is an irregular tearing of soft tissue 4. Puncture/stab/wound 5. Avulsion wound 6. Contusion wound/bruise/ wound • A closed wound that results in tissue damage and ruptured blood vessels • If internal organs are contused serious effect may result
  199. 199. HA(MSN) 199 Types of wound healing 1. Primary intention • The wound is clean and no tissue loss • The wound closes rapidly because there are no gaps in the tissue • Edges can be approximated with suture/staples (clip)/ wound closure strips • Risk of infection is low • Fine scar will remain • E.g.: surgical incision 2. Secondary intention • Loss of tissue • Irregular edge, large wound with blood clot • Edge can not be approximated • Greater risk of infection • Longer healing time • Granulation tissue fills in wound • Visible scar formation • E.g.: wounds from trauma, ulceration and infection
  200. 200. HA(MSN) 200 Cont’d… 3. Tertiary intention • Large area of tissue loss • Contaminated wound • Delayed closure even with suture that breaks down and re-sutured latter • Results in deeper and wider scar • E.g.: primary wound which was infected
  201. 201. HA(MSN) 201 Phases of wound healing Inflammatory phase • Occurs immediately after an injury and lasts 4-6 days • Small blood vessels become more permeable • Presence of edema • Pain and tenderness occurs • Phagocytosis occurs • The client shows elevated temperature, leukocytosis and generalized malaise
  202. 202. HA(MSN) 202 2. Proliferative or granulation phase – Begins between 1 and 4 days after the injury and ends 14-21 days later – Rapid growth of epithelial cells – Rebuilding of vascular capillary network and collagen tissue – Collagen fibers fill in the gap and form the scar – Wound scar tissue is very fragile and susceptible to re-injury – The color is red because of increased blood flow
  203. 203. HA(MSN) 203 cont’d… 3. Maturation or wound remodeling phase • Wound contraction begins between 14-21 days, after the injury and lasts up to 2 years • Scar shrinks and become flat • Less red as the capillary regress
  204. 204. HA(MSN) 204 Factors that delay wound healing Age • Nutrition- adequate nutrition that includes essential amino acids, vitamin A, C, and zinc is essential for normal wound repairs • Infection- • Hormonal influences- the therapeutic administration of adrenal corticosteroids can make: • Impairs phagocytosis • Inhibit fibroblast proliferation and function • Depresses the formation of granulation tissue • Inhibit wound contraction • Mask presence of infection by impairing normal inflammatory response • Blood supply- • Poor blood flow may occur as result of swelling, arterial and venous pathology
  205. 205. HA(MSN) 205 • Wound separation • Presence of foreign bodies- • Smoking- vasoconstriction caused by smoking, decreases blood supply to the wound, the carbon in smoke binds with hemoglobin and further diminishes oxygenation • Obesity- the bulk and weight of adipose tissue causes poor vascularity • Fluid and electrolyte balance- • Immuno-suppression- • Radiation therapy- the blood supply in irradiated tissue is decreased
  206. 206. HA(MSN) 206 • Handling of tissue- rough handling causes injury and delayed healing • Edema- reduces blood supply by exerting pressure on blood vessels • Medications -Anti-inflammatory- decrease epithelization and wound contraction -Corticosteroids- may mask presence of infection by impairing normal inflammatory response -Anticoagulants- may cause hemorrhage • Patient over activity- prevents approximation of wound edges
  207. 207. HA(MSN) 207 Cont’d • Wound stressors- like vomiting, coughing heavily, and straining produces tension on wounds and destroys granulation tissue that prevents apposition of wound edges • Poor general health- alters cellular function • Duration of surgical procedure- the longer the time the higher the delay of wound healing • Drainage accumulation- accumulation of drainages favors bacterial growth • Bleeding (hemorrhage)- bleeding sites becomes a growth media for microorganisms
  208. 208. HA(MSN) 208 Complications of wound healing • Hypertrophic scar and keloids- due to excess production of collagen tissue • Contracture- shortening of muscle or scar tissue • Delviscence • Separation and disruption of previously joined wound edge • It can be due to infection, inflammation, weak granulation tissue. • Evisceration- excess growth of tissue protrudes above the surface of the healing wound. • Adhesions- binding two surfaces or structures that normally are separate
  209. 209. HA(MSN) 209 Cont’d… • Major organ dysfunction- • Herination- the surface layer remains intact but the deep layers separate permitting the underlying muscles/organs bulge • Fistula- draining tunnel may form between two organs • Sinus tract- an abscess may form in deeper tissues and form a tunnel to the out side of the body • Hematoma- collections of blood or serum in wound (seroma) • Infection- • Hemorrhage-
