Wound healing involves three phases - inflammatory, proliferative, and remodeling. Factors like wound classification, morphology, and healing intention (primary vs secondary) determine the healing process. General factors like nutrition, immunity, and associated diseases as well as local factors like site, contamination, and tension affect wound healing. Complications include infection, breakdown, hernia, and abnormal scarring. The principles of wound management are to clean contaminated wounds and close primarily when possible to promote rapid healing with minimal scarring.
This document discusses wound classification, types of wound healing, and the wound healing process. It classifies wounds based on degree of contamination and causal agents/morphology. The types of wound healing include first, second, and third intention. The phases of wound healing are the lag/preparatory phase, repair/proliferative phase, and maturation phase. Key elements of wound healing include epithelialization, wound contraction, and connective tissue formation. Factors affecting wound healing and potential wound complications are also outlined.
This document discusses wound classification, healing, and care. It classifies wounds as closed vs open, tidy vs untidy, acute vs chronic, and by surgical risk. The phases of wound healing are hemostasis and inflammation, proliferative, and maturation/remodeling. Factors affecting healing include ischemia, infection, foreign bodies, and systemic issues like diabetes or smoking. Abnormal healing can cause hypertrophic or keloid scarring. Wound management involves assessment, preparation, closure if needed, dressing, and use of adjuncts like antibiotics or tetanus prophylaxis. Special wounds from bites require thorough irrigation, possible antibiotics, and rabies prophylaxis.
The document summarizes the structure and function of skin, the process of wound healing, and factors that can affect wound healing. It discusses the following key points:
- Skin is composed of several layers including the epidermis, dermis, and subcutaneous layer. Its structure varies depending on its location on the body.
- Wound healing involves regeneration of epithelial tissue and formation of connective scar tissue. It occurs through the phases of inflammation, proliferation, and remodeling.
- The three classifications of wound healing are primary intention, secondary intention, and delayed primary healing. Primary intention healing results in minimal scarring.
- The phases of wound healing involve coagulation, inflammation, proliferation, epithelialization
This document discusses wound management. It defines a wound and outlines the specific objectives of understanding wound classification, types, healing process, and management. It describes the typical stages of wound healing as inflammatory, proliferative, and remodeling phases. Wounds are classified by factors like depth, contamination level, and amount of tissue loss. Primary intention healing involves closing tissue surfaces while secondary and tertiary intention involve tissue loss. Proper wound management includes assessment, debridement, irrigation, antibiotics, dressing and factors that can complicate healing.
The primary goal of wound care is facilitating the natural healing processes rather than technical repair alone. Wound healing involves inflammatory, proliferative, and remodeling phases. Wound preparation includes anesthesia, hemostasis, debridement, cleaning, and closure or dressing. Factors like infection, nutrition, tissue ischemia, and tension can impair healing. Proper wound evaluation and management are essential for optimal healing outcomes.

This document discusses wound healing and the healing process after tooth extraction. It defines a wound and classifies wounds based on origin, contamination, and depth. The two main processes of healing are regeneration and repair. Repair involves granulation tissue formation and wound contraction. There are two types of wound healing: primary intention and secondary intention. Healing after tooth extraction involves blood clot formation, fibroblast proliferation, angiogenesis, and bone remodeling over 4 weeks. Complications can include dry socket and fibrous union.
The mediastinum is the region within the chest between the lungs containing the heart and other thoracic organs. It is divided into superior, anterior, middle and posterior compartments. Common tumors of the mediastinum include thymomas in the anterior-superior compartment, lymphomas throughout and neurogenic tumors in the posterior compartment. Thymomas are often asymptomatic but can cause chest pain, dyspnea and superior vena cava obstruction. Diagnosis is made through imaging like CT and biopsy. Treatment is surgical resection with chemotherapy or radiation for advanced stages. Retrosternal goiters are usually secondary extensions from the neck but can also be primary. They may cause compressive symptoms and require surgical removal.
Day surgery offers advantages for both patients and healthcare providers by reducing disruption and costs compared to overnight stays. Success requires efficient coordination across admission, the procedure itself, recovery, and safe discharge within 12 hours. Selection criteria evaluate medical fitness, social support, and whether the planned procedure is suitable for day surgery. Preoperative assessment optimizes patient health while clear discharge standards ensure recovery before leaving. Common day surgery procedures involve areas like abdominal, breast, orthopedic, and vascular operations. Emergency minor cases can also sometimes be managed with same-day admission and discharge.

It then details the external structures of the nose including the bones and cartilages. It discusses the internal structures including the walls, roof, and floor of the nasal cavities. It also summarizes the blood supply, nerve supply, lymphatic and mucosal drainage of the nose. Finally, it provides details on each of the four paranasal sinuses including their locations, relations to surrounding structures, and functions.
The nose and paranasal sinuses develop from the frontonasal process. The nose has external and internal structures. Externally, cartilage and bone provide structure, while internally the nasal cavities contain three turbinates and three meatuses on each side. The paranasal sinuses include the frontal, ethmoid, maxillary, and sphenoid sinuses. The sinuses are lined with ciliated respiratory epithelium and contain ostia that drain into the nasal cavities. The nose and sinuses receive blood supply from the external and internal carotid arteries and are innervated by branches of the trigeminal and facial nerves. Lymphatic drainage occurs to local cervical nodes.
The oral cavity and oropharynx are described in detail. The oral cavity extends from the lips to the oropharyngeal isthmus and includes structures like the cheeks, gums, hard palate, oral tongue, and floor of mouth. The oropharynx is behind the soft palate and serves as a passageway for food and air. It includes the base of tongue, palatine tonsils, soft palate, and pharyngeal wall. Both areas have detailed descriptions of anatomy, blood supply, nerve supply, lymphatic drainage and functions.
The inner ear consists of the bony labyrinth surrounded by fluid-filled membranous labyrinth containing the cochlea, vestibule and semicircular canals. The cochlea contains the organ of Corti which is the sensory organ for hearing and consists of hair cells. The vestibule and semicircular canals contain maculae and cristae which are sensory organs for balance. The inner ear develops from the otic placode and is complete by 16 weeks of gestation. The vestibulocochlear nerve transmits signals from the inner ear hair cells and sensory epithelia.
The lateral wall of the nose contains three bony projections called conchae or turbinates that increase the surface area for air conditioning. The lateral wall is formed by bones, cartilages, and soft tissues and separates the nose from the ethmoid sinuses above and the maxillary sinus below. The osteomeatal complex is an important drainage pathway consisting of the maxillary sinus ostium, ethmoid infundibulum, middle meatus, ethmoid bulla, and uncinate process. It drains the frontal and maxillary sinuses and anterior ethmoid cells. The lateral wall receives blood supply from the internal and external carotid arteries and drains venously and lymphatically. Sensation is provided by
Anatomy of Nasopharynx and Eustachian Tube.pptxHtet Ko
The nasopharynx connects the nasal cavity to the oropharynx. It contains openings for the eustachian tubes and is lined with lymphoid tissue including the adenoids. The eustachian tubes connect the middle ears to the nasopharynx and equalize pressure on both sides of the eardrum. They open during swallowing and yawning due to the action of surrounding muscles to ventilate the middle ear. Dysfunction of the eustachian tubes can lead to problems like ear infections or pressure differences across the eardrum.
The organ of Corti is located in the cochlea between the scala tympani and scala media. It is the sensory organ for hearing and contains hair cells that transduce sound vibrations into nerve impulses. The organ of Corti sits on the basilar membrane and contains three key cell types - inner and outer hair cells that detect sound, and supporting cells that provide structure. Inner hair cells transmit signals to the brain while outer hair cells modulate their function. Together, movement of the basilar membrane causes the hair cells to bend, opening ion channels and generating nerve impulses that are transmitted to the brain for interpretation as sound. The unique ion composition within the cochlea, maintained by
Shock is defined as inadequate tissue perfusion due to decreased oxygen delivery or utilization leading to cellular hypoxia. It is a life-threatening condition characterized by circulatory failure and hypotension. There are four main types of shock: distributive, hypovolemic, cardiogenic, and obstructive. Septic shock, a form of distributive shock, results from a dysregulated immune response to infection leading to vasodilation and hypotension. Management of septic shock involves fluid resuscitation, vasopressor support, antibiotic treatment, and control of the underlying infection. The pathophysiology is complex, involving an interplay between the immune system, inflammatory response, and cardiovascular system.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

2. Wound & Wound Healing
Definition:
Breach in continuality of epithelial lining
surface due to injury & trauma.
Classification of wound:
Depend on degree of contamination.
Depend on causal agents/morphology.
3. Depend on degree of contamination.
Clean wound
Wound without contamination.
(e.g. Clean surgical wound under aseptic condition;
Thyroid, Breast, Lipoma Surgery.)
Clean contaminated wound
Wound with minimal or potential contamination.
(e.g. Surgical wound made on potentially
contaminated area (upper GI surgery-stomach,
biliary)
Traumatic clean wound within six hours after
trauma.)
4. Contaminated wound
Wound with gross contamination.
(e.g. Surgical wound made on contaminated area
(colonic surgery)
Traumatic wound > six hours, with
contaminated soil)
Dirty/ Septic wound
Wound contaminated with pathogenic organisms
(e.g. Wound made on gross sepsis-peritonitis,
abscess)
5. Depend on Causal agents/
Morphology
Incised wound
Due to sharp weapon
Minimal tissue loss, edge opposed together & even
Rapid healing when wound is clean & closed
primarily, increased tensile strength, minimal scar
Lacerated wound
Due to blunt object
Variable amount of tissue loss, haematoma, edge is
uneven & rages
More time need to heal (because of increase tissue
loss & presence of haematoma) reduced tensile
strength, increased scar
6. Depend on Causal agents/
Morphology
Crush wound
Tissue crush between two hard objects
Large amount of tissue loss, haematoma,
unexpected amount of devitalised tissue at
first, and then loss of tissue depend on force
& extend of crush injury
Delay wound healing, reduced tensile
strength, increased scar
Penetrating wound
Due to sharp & pointed weapon
7. Types of Wound Healing
First intention
In clean surgical wound/incised wound, wound edge
opposed together by suture wound healing is
rapid from edges as well as base, increased tensile
strength & minimal scar formation
Second intention
In case of contaminated/dirty wound with variable
amount of tissue loss- healing arise from base
(contained all 3 elements of wound healing)- healing
is delayed & need long time- reduced tensile strength,
increased scar formation
8. Third intention
In case of contaminated wound with minimal tissue
loss, wound wait to clean as open wound ( due to
infection more susceptible in close wound)- closed
the wound with suture when the wound is clean (
delay primary closure) or secondary closure. Wound
healed as first intention and known as third intention.
9. Elements of Wound Healing
1. Epithelialization
Migration, proliferation of epithelial tissue from the
edges & epidermal layer of wound to cover the
wound
2. Wound contraction
In open wound, the size of wound become smaller
by contraction of myofibroblast to wound healing
3. Connective tissue formation
Main body of wound is united by synthesis & lysis of
collagen tissue from fibroblast & new capillary
formation ( granulation tissue)
10. Phase of Wound Healing
1. Lag (or) Preparatory phase
First few hours to days of wound- infiltration of
neutrophil & macrophages- demolition of
inflammatory exudate & devitalised tissue
2. Repair (or) Proliferated (or) Fibroblastic phase
First few days of wound- macrophages- attract the
fibroblast & synthesis of collagen tissue &
intercellular ground substance & new formation of
blood vessels ( granulation tissue) filled up the
wound wound healing.
11. 3. Maturation (or) Differentiation phase
Reduced activity of fibroblast & increasing tensile
strength of wound need months to years until
normal tensile strength regained (very rare).
50% to 70% of tensile strength regained by the end
of six months
12. Process of wound healing
Epidermal events
Dermal events
Collagen production
13. Epidermal events
Particularly in surgical wd, incised wd within few
hrs
Primary single layer of epithelial cell starts to migrate
from edge to form delicate covering over wd
Followed by epithelial cell proliferation from epidermal
cells
(Implantation dermoid – In small penetrating wd(
needle prick) down growth of epidermal cell –keratin
forming cyst within dermis known as implantation
dermoid
14. Dermal events
Within few hrs, mild acute inflammatory
infiltration of neutrophil into and aroundwd
followed by migration of macrophages (1-2)after
wound
Demolition and removal of inflammatory exudate and
tissue debris
Restoration of tensile strength of sub epithelial
connective tissue
• Chemoattraction of fibroblasts synthesis secretion of collagen
and ground substance
• Expansion of fibroblast population
• Secretion of extracellular connective tissue protein for
fibroblast
15. Ingrowth of new small bld v/s
Budding of new endothelial cell from intact bld
v/s of edges
Chemoattraction of these new bld vs into
connective tissue of wd
16. Collagen production
Over half of collagen made up with 3 amino
acids; lysine, hydroxyprolene, prolene
Fibroblast ; synthesis new collagen intercellular
ground substance production of 3 main amino
acids and cross linkage of each other >
connective t/s formation> tensile strength of wd
a/acid precursor---hydroxylation-- collagen
(protocollagen) O2, vite, Fe++
17. Tensile strength depends on production of
amount of collagen and their orientation. This
process is maintained by production and
destruction of collagen (collagen synthesis and
lysis)
Inbalance between this process>wd
complication
Decrease synthesis ,increase lysis > impaired wd
healing and dehiscence
Increased synthesis, decrease lysis > hypertrophic
scar keloid formation
18. Factors affecting wound healing
General factors
(1) Age - young age - increased blood supply- good
wound healing
- old age - reduced blood supply & associated
diseases- impair wound healing
(2) Nutritional status
(1) Overnutrition - (2) Undernutrition
19. (1) Overnutrition - obesity- increased fatty tissue-
(a) reduced supportive tissue to blood vessels-
fragile, easy to bleed
(b) retraction of blood vessel- difficult to control
healing
(c) increased tissue destruction, dead space
(2) Undernutrition
hypoproteinaemia- impair amino acid synthesis
hypovitamin C (surgery) – impair collagen
synthesis (hydroxylation)
hypovitamin A – epidermal growth reduced
zinc – impair wound healing- because of decrease
collagen synthesis
20. (3) Associated diseases
-jaundice
-uraemia
-anaemia-reduced Hb – decreased oxygen carrying
capacity
-diabetes mellitus – decreased immunity, reduced
blood supply, increased infection
-impaired cardiopulmonary status- reduced oxygen
supply to tissue
(4) Immunity
-reduced immunity- increase infection-
due to disease - burn, DM, HIV, trauma, Ca
due to drugs - steroid, chemotherapy,
immunosuppressive therapy
Increased collagen breakdown
21. Local factors
1. Site- face- increased blood supply- increased
wound healing
2. Presence of foreign body + contamination-
increased infection- reduced oxygen supply-
impaired wound healing
3. Underlying vascular diseases –artery-
reduced blood supply, venous stasis-
reduced oxygen supply
4. Presence of tension- reduced blood supply-
to wound- haematoma, dead space
oxygenation
infection
24. Hypertrophic Keloid
Time factor Regress after 6 months Continue after 6 months
Tendency No previous Previous tendency
Site Any site Over the bony
prominent
e.g. sternum
Extend beyond
the margin of
wound
Never Presence
Treatment No active treatment required Active treatment
required – injection
steroid, pressure
dressing, R/T
Complication - Malignant change –
Marjolin’s ulcer
25. Principle of wound management
Clean wound – closed by primary intention
Contaminated wound – change to clean wound
– closed
Depend on - amount of contamination
- type of wound
26. A. Specific treatment
Contaminated wound- change to clean wound by-
1. “wound toilet”- irrigation of wound with sterile water
including antiseptic solution - to reduce contamination
& remove foreign body
2. “wound debridement”- excision of dead & devitalised
tissue[pseudo tumour approach] under appropriate
GA/LA/Reagional
Skin – as little as possible (easy to close the wound)
Subcut :fat & tls – as much as possible
Mls – till bleed ( viable mls )
Tendon – color suture for delayed repair
Nv – primary repair / delayed repair mark with
suture
27. Bld v/s -Small v/s – haemostasis
-Major v/s – primary repair / graft
Bone - detached bone & pieces from periosteum
removed
- Reduction & traction by external fixator or POP
with windows for dressing
Care of internal organ damage - chest tube for 10
haemothorax
Wound not closed primarily ( left open until clean )
Daily dressing untill clean
28. B. Supportive / symptomatic treatment
- Analgesic & antiinflammatory drugs - for pain &
inflammation
- Antipyretic drugs – pt with febrile reaction
- Antibiotic – according to possible organ ( or ) C&S
result
- tetanus prophylaxis – tetanus toxoid – active for
regular immunized person
– both active & passive in pt
who has no regular immmunization
- Nutritional support
- Correct the factors which delayed the wd healing
e.g Correction of Anaemia, Diabetes mellitus
29. C. Treatment of clean wd / wd become clean from
contaminated wound
- Skin closure d/on type of wound
( 1 ) when skin can oppose together eg .in incise &
lacerated wound ( less tissue loss )
- Primary closure – for clean wound.
- delayed primary closure – for contaminated wound.
30. - secondary closure – clean wound become
contaminated
- after primary closure & remove the suture and then
wait for clean wound and then reapplication of
suture
( 2 ) when skin cannot oppose together (tissue loss very
much) crush wound
a. Close the wound by – skin graft ( to fasten the wd
healing ) ( or )
b. Left the wound open and healing from base of
wound ( wd complication increased )
