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

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
HA(MSN) 5

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
HA(MSN) 6

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 .
HA(MSN) 7

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
HA(MSN) 8

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
HA(MSN) 9

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
HA(MSN) 10

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
HA(MSN) 11

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
HA(MSN) 12

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
HA(MSN) 13

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
HA(MSN) 14

15. Vascular skin lesions
• a lesion that originated from a blood vessel
– Petechia/Purpura
– Ecchymosis
– venous star
HA(MSN) 15

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
HA(MSN) 16

17. Assessing the skin
• Assessment includes a thorough
- history taking,
-inspection and
-palpation of the skin.

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).
HA(MSN) 25

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
HA(MSN) 26

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. 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
HA(MSN) 33

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)

A. 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.
HA(MSN) 38

39. HA(MSN) 39

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
HA(MSN) 40

41. Hypersensitivity reactions
HA(MSN) 41

swelling, papules, blisters, oozing and crusts.
• In the sub-acute stage the skin is still red but
becomes drier and scalier and may show
pigment change.
• In the chronic stage
-lichenification,
-excoriation,
-scaling and cracks are seen
HA(MSN) 42

43. Types of eczema
Atopic eczema
- is a chronic relapsing skin disorder that usually
begins in infancy and is characterized principally
by dry skin and pruritis, consequent rubbing and
scratching lead to lichenification
• This patient has a genetic predisposition for
hypersensitivity reactions such as asthma, allergic
rhinitis, and chronic urticaria.
– The eczema comes and goes
– The eczema triggered by dryness of the skin,
infections, heat, sweating, contact with allergens or
irritants and emotional stress.
HA(MSN) 43

– Behind ears, above and in between
eyebrows
– In nasolabial folds, Sternum
– In between the shoulder blades, in axillae
– Groin , Perianal area
HA(MSN) 47

48. Seborrhoic eczema…

HA(MSN) 61

62. Psoriasis
• Is a chronic recurrent, hereditary, non infectious
disease of the skin caused by abnormally fast
turn over of the epidermis

normal and as a result the epidermis is not able
to develop normally, therefore it doesn’t allow
formation of the normal protective layer of the
skin.

145. BURN
HA(MSN) 145

146. HA(MSN) 146

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.
HA(MSN) 147

148. Assessment of burn injury depends on:
1. cause and temperature of the burning
agent.
2. location
3. duration of contact with the agent
HA(MSN) 148

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.
HA(MSN) 149

150. HA(MSN) 150

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
HA(MSN) 151

152. HA(MSN) 152

153. Deep partial thickness
HA(MSN) 153

154. HA(MSN) 154

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
HA(MSN) 155

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
HA(MSN) 156

157. HA(MSN) 157

158. HA(MSN) 158

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
HA(MSN) 159

160. extravasations
HA(MSN) 160

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.
HA(MSN) 161

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
HA(MSN) 162

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
HA(MSN) 163

164. Adult Infant (child)
• Head 9% 18%
• Abdomen and Thorax
- Front 18% 18%
- Back 18% 18%
• Genitalia 1% -
• Hands
- Right 9% 9%
- Left 9% 9%
• Leg
-Right 18% 14%
-Left 18% 14%
Total 100% 100%
HA(MSN) 164

165. HA(MSN) 165

166. HA(MSN) 166

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----------------------- 7%
• Neck----------------------- 2%
• Anterior trunk---------- 13%
• Posterior trunk--------- 13%
• Right buttock------------ 2 ½ %
• Left buttock-------------- 2 ½ %
HA(MSN) 167

168. • Genitalia------------------ 1%
• Right upper arm--------- 4%
• Left upper arm----------- 4%
• Right lower arm---------- 3%
• Left lower arm------------ 3%
• Right hand----------------- 2 ½ %
• Left hand------------------- 2 ½%
• Right thigh---------------- 9 ½%
• Left thigh------------------ 9 ½%
• Right leg------------------- 7%
• Left leg--------------------- 7%
• Right foot----------------- 3 ½%
• Left foot------------------- 3 ½%
100%
HA(MSN)
168

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
HA(MSN) 169

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
HA(MSN) 170

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
HA(MSN) 171

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
HA(MSN) 172

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
HA(MSN) 173

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
HA(MSN) 174

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.
HA(MSN) 175

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)
HA(MSN) 176

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
HA(MSN) 177

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
HA(MSN) 178

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
HA(MSN) 179

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
HA(MSN) 180

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
HA(MSN) 181

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
HA(MSN) 182

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
HA(MSN) 183

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
HA(MSN) 184

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
HA(MSN) 185

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
HA(MSN) 186

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.
HA(MSN) 187

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
HA(MSN) 188

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
HA(MSN) 189

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
HA(MSN) 190

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
HA(MSN) 191

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
HA(MSN) 192

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
HA(MSN) 193

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
HA(MSN) 194

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
HA(MSN) 195

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
HA(MSN) 196

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
HA(MSN) 197

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
HA(MSN) 198

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
HA(MSN) 199

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
HA(MSN) 200

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
HA(MSN) 201

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
HA(MSN) 202

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
HA(MSN) 203

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
HA(MSN) 204

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
HA(MSN) 205

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
HA(MSN) 206

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
HA(MSN) 207

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
HA(MSN) 208

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)
