INTRODUCTION TO MINOR OFFICE SURGERY

Surgery: Branch of medicine that deals with operative and manual procedures

for:

Correction of deformities and defects

Repair of injuries

Diagnosis and treatment of certain diseases

3


Minor Office surgery: Surgical procedure that is restricted to:

The management of minor conditions

Does not require the use of general anesthesia

4


Characteristics of minor surgical procedures:

Performed in an ambulatory healthcare facility (e.g., physician’s office, clinic)

Performed in a short period of time

Less than 1 hour

5


Characteristics of minor surgical procedures:

Requires either:

Local anesthesia

Topical anesthesia

No anesthesia

Can be performed with a minimum amount of discomfort to the patient

Does not pose a major risk to

Life

Function of an organ

Body parts

6


Minor office surgery performed in a medical office

Insertion of sutures

Sebaceous cyst removal

Incision and drainage of infections

Mole removal

Needle biopsy

Cervical biopsy

Ingrown toenail removal

7


Physician explains nature of surgical procedure and risks to patient

Offers to answer questions

8


MA responsible for

Explaining patient preparation

Obtaining patient's signature on consent to treatment form

9


Consent to Treatment Form

10


MA responsible for

Additional responsibilities

Preparing treatment room

Preparing patient

Preparing MOS tray

Assisting the physician during the procedure

Administering postoperative care to the patient

Cleaning the treatment room

11


Patient positioned and draped according to procedure

Skin is prepared as specified by the physician

Shave skin around operative site

Cleanse skin

Apply antiseptic: reduces number of microorganisms

12


Prepare minor office surgery tray using sterile technique

Instruments and supplies on tray vary based on:

Type of surgery

Physician preference

During the surgery:

Assist the physician

Lend support to the patient

13


Remain with patient after surgery

Safety precaution

To explain postoperative instructions

Remove and properly care for used instruments/supplies

Clean the treatment room

14

SURGICAL ASEPSIS

Also known as sterile technique

Refers to practices that keep objects and areas sterile or free from all

living microorganisms and spores

Protects patient from pathogens that may enter and cause disease

15

SURGICAL ASEPSIS

Surgical asepsis employed when

Caring for broken skin (open wound)

Skin surface is penetrated (surgical incision for a mole removal)

Administration of an injection

Body cavity is entered that is normally sterile

Example: insertion of a urinary catheter

16

SURGICAL ASEPSIS

Sterility of instruments and supplies is achieved:

Through use of disposable sterile items

Sterilizing reusable articles

Sterile object that touches any nonsterile object is considered

contaminated

Must not use

If in doubt about sterility of article

Do not use it – replace it with a sterile article

17

SURGICAL ASEPSIS

Sanitizing hands renders them medically aseptic

Sanitize hands before and after a surgical procedure

Sterile gloves must be worn when picking up or transferring sterile articles

18

SURGICAL ASEPSIS

Guidelines to Maintain Surgical Asepsis

Prevent sterile packages from becoming wet

Wet pack draws microorganisms into pack resulting in contamination

1-inch border around sterile field is considered contaminated

19

SURGICAL ASEPSIS


Always face the sterile field

If you must leave: cover the sterile field with a sterile towel

Hold all sterile articles above waist level

If out of sight: might become contaminated

Place all sterile items in center of sterile field

20

SURGICAL ASEPSIS


Do not spill water or solution on sterile field

Draws microorganisms up onto field from area beneath field, causing

contamination

Do not talk, cough, or sneeze over a sterile field

Water vapor from nose, mouth, and lungs contaminates sterile field

21

SURGICAL ASEPSIS


Do not reach over a sterile field

Dust or lint from clothes may fall onto the field

Unsterile clothing may accidentally touch the sterile field

Do not pass soiled dressings over the field

Always acknowledge if you contaminate the sterile field

Steps can be taken to regain sterility

22

instrument

Examples: box lock, ratchet, serrations

55


MA works with instruments when:

Setting up a sterile tray

Performing procedures (e.g., suture removal)

Cleaning up after MOS

Sanitizing and sterilizing instruments

56


Guidelines

Handle instruments carefully

Dropping on floor or throwing into a basin: could damage them

57


Guidelines

Do not pile in a heap

Become entangled – could be damaged when separated

Keep sharp instruments separate from rest of instruments

Prevents damage or dulling the cutting edge

58


Guidelines

Keep instruments with ratchets in open position when not in use

Prolongs proper functioning of ratchet

Rinse blood and body secretions off as soon as possible

Prevents them from drying and hardening on instrument

59


Guidelines

Always use instrument for intended purpose

Substituting instruments could damage an instrument

Sanitize and sterilize instruments using proper technique

60

COMMERCIALLY PREPARED STERILE PACKAGES

Frequently used in medical office

May contain

One article (sterile dressing)

Complete sterile setup (suture removal)

Directions for opening package stated on outside of package

Carefully follow directions to prevent contamination of sterile contents

61


Guidelines

Do not pile in a heap

Become entangled – could be damaged when separated

Keep sharp instruments separate from rest of instruments

Prevents damage or dulling the cutting edge

62


To open a peel-apart package

Peel-pack: has edge with two flaps that can be pulled apart:

Grasp each nonsterile flap between bent index finger and extended thumb

Roll hands outward to pull apart

Inside of wrapper and contents are sterile

Must not be touched with bare hands

63


Opening a Peel-Apart Package

64


Contents of peel-apart package can be placed on sterile field by

Stepping back

Prevents wrapper and MA’s hands from crossing over the sterile field

Ejecting or "flipping" contents on center of the field

65


Contents of peel-apart package can be placed on sterile field by

Removing contents with a sterile gloved hand

Used when physician needs additional supplies during MOS

MA opens pack: physician removes contents with gloved hand

66


Inside of peel-apart package can be used as sterile field

Open peel-apart package completely

Lay flat on a clean dry surface

67

WOUNDS

Wound: Break in continuity of an external or internal surface caused by

physical means

Can be

Accidental

Intentional: physician makes an incision during MOS

68

WOUNDS

Closed wound: Injury to underlying tissues without break in skin surface

or mucous membrane (contusion)

69

WOUNDS

Closed wound: Injury to underlying tissues without break in skin surface

or mucous membrane (contusion)

Contusion: Tissues under skin are injured

Often caused by blunt object

Commonly occurs with fractures, sprains, strains, black eyes

Blood vessels: rupture; blood seeps into tissues – results in bluish

discoloration of skin; color turns greenish-yellow after several days

70

WOUNDS

Contusion

71

WOUNDS

Open wounds: Break in skin surface or mucous membrane that exposes

underlying tissue

Incision: Clean smooth cut caused by a sharp instrument (e.g., knife, razor,

glass)

Deep incision: accompanied by profuse bleeding; may damage muscles,

tendons, nerves

72

WOUNDS


underlying tissue

Laceration: Tissues are torn apart, leaving ragged and irregular edges

Can be caused by: dull knife, large objects driven into skin, heavy

machinery)

Deep lacerations: result in profuse bleeding; scar often develops

73

WOUNDS

Laceration

74

WOUNDS


underlying tissue

Puncture: Wound made by sharp pointed object piercing skin layers (e.g.,

nail, needle, splinter, knife, bullet, animal bite)

Very small opening; bleeding is usually minor

Tetanus bacteria: grow best in warm anaerobic environment such as a

puncture

May need a tetanus booster

75

WOUNDS

Puncture

76

WOUNDS


underlying tissue

Abrasion (scrape): Outer layers of skin are scraped or rubbed off (e.g., falling

on gravel and floors)

Blood oozes from ruptured capillaries

Results in skinned knees and elbows

77

WOUND HEALING

Skin: protective barrier for body; considered first line of defense

When skin is broken: easy for microorganisms to enter and cause infection

78

PHASE 1

Inflammatory Phase

Begins as soon as body is injured

79

PHASE 1

Lasts 3 to 4 days

Fibrin network forms

Results in blood clot: "plugs" up opening and stops flow of blood

Blood clot becomes scab

80

PHASE 1

Phase 1: Inflammatory Phase

81

PHASE 1

Inflammatory process occurs

Inflammation: Protective response of the body to trauma and entrance of

foreign matter (microorganisms)

Blood supply increases: brings WBCs and nutrients to the site to assist in

the healing process

82

PHASE 1 Inflammatory process occurs

Four local signs of inflammation

Redness

Swelling

Pain

Warmth

Purpose of inflammation: to destroy invading microorganisms and remove

damaged tissue debris so proper healing can occur

83

PHASE 2

Granulation Phase

Lasts 4 to 20 days

Fibroblasts migrate to wound: begin to synthesize collagen

Collagen: White protein that provides strength to wound

84

PHASE 2

Fibroblasts migrate to wound: begin to synthesize collagen

As amount of collagen increases:

Wound becomes stronger

Decreases chance that wound will open

Growth of new capillaries: provides damaged tissue with blood supply

Tissue becomes translucent red color: known as granulation tissue (fragile,

shiny, bleeds easily)

85

PHASE 2

Phase 2: Granulation Phase

86

PHASE 3

Maturation Phase

Can last for up to 2 years

Collagen continues to be synthesized

Granulation tissue hardens to white scar tissue

Scar tissue is not true skin: does not contain nerves or have blood supply

87

PHASE 3

Phase 3: Maturation Phase

88

WOUND HEALING

Always inspect wound when providing wound care

Observe for

Signs of inflammation

Amount of healing

Chart in patient's record

89

WOUND DRAINAGE

Exudate (drainage): Material (fluid and cells) that has escaped from blood

vessel during inflammatory process

Inspect wound for drainage and chart in patient's record

90

WOUND DRAINAGE

Types of Exudates:

Serous exudate: consists of serum

Clear and watery

Example: fluid in blister from a burn

91

WOUND DRAINAGE

Types of Exudates:

Sanguineous exudate: red and consists of RBCs

Results when capillaries are damaged and blood escapes

Seen with open wounds

Color – bright red: fresh bleeding; dark red: older bleeding

92

WOUND DRAINAGE

Types of Exudates:

Purulent exudate: contains pus

Pus: consists of leukocytes, dead tissue debris, dead and living bacteria

Usually thick and has unpleasant odor

White in color: may acquire tinges of pink, green, or yellow (depending on

infecting organism)

Suppuration: Process of pus formation

93

WOUND DRAINAGE

Types of Exudates:

Mixed exudates

Serosanguineous exudate: clear and blood-tinged drainage

Purosanguineous exudate: pus and blood – often found in new wound

that is infected

94

STERILE DRESSING CHANGE

Surgical asepsis must be maintained when applying a dry sterile dressing

(DSD) to an open wound

Must prevent infection in clean wounds and decrease infection in infected

wounds

95


Function of a sterile dressing

Protect the wound from contamination and trauma

Absorb drainage

Restrict motion

96


Dressing material used (size, type, amount) depends on:

Size and location of wound

Amount of drainage

97


Sterile gauze pads used in medical office

Come in a variety of sizes

2 x 2

3 x 3

4 x 4 (most frequently used)

Have tendency to stick to the wound

98


Nonadherent pads

Surface impregnated with agents that prevent dressing from sticking to wound

Example: Telfa pads (shiny side placed next to skin)

Often used for burns

99

SUTURES

10.Explain the method used to measure the

diameter of suturing material.

11.Describe the two types of sutures (absorbable

and nonabsorbable), and give examples of their

uses.

12.Categorize suturing needles according to type of

point and shape.

Lesson 25.2

100

SUTURES

Used to

Close a surgical incision

Repair accidental wound

101

SUTURES

Purpose of sutures

Approximate (bring together) edges of wound with surgical stitches

Holds in place until proper healing occurs – so that wound can withstand

ordinary stress; no longer needs support from sutures

102

SUTURES

Purpose of sutures

Protect wound from contamination

Minimize amount of scar formation

Local anesthetic: to numb area before insertion of sutures

103

TYPES OF SUTURES

Absorbable sutures

Made from surgical gut or synthetic materials that are gradually digested and

absorbed by the body

Ranges from 7 days to several months after insertion depending on type of

tissue being sutured and size and type of absorbable suture

104

TYPES OF SUTURES

Absorbable sutures

Surgical gut: made from sheep or cow intestine (Surgigut)

Gradually digested by tissue enzymes and absorbed by body – 7–21 days

after insertion

Plain surgical gut: rapid absorption time

Chrome surgical gut: slower absorption time

105

TYPES OF SUTURES

Absorbable sutures

Synthetic materials

Dexon

Vicryl – mainly used in hospital setting during surgery

106

TYPES OF SUTURES

Nonabsorbable sutures

Not absorbed by body

Sutures either remain in skin permanently or are removed

Used to suture skin

Frequently performed in medical office

Types: silk, nylon, polyester, polypropylene, polybutester, stainless steel,

surgical skin staples

107

TYPES OF SUTURES

Nonabsorbable Sutures

108

SUTURE SIZE AND PACKAGING

Measured by gauge: refers to diameter of the suture

Size ranges from numbers below 0 (pronounced "aught") to numbers

above 0

Size increases with numbers above 0 and decreases with numbers below 0

Example:

7-0: very fine sutures

5: heavy sutures

109


Nonabsorbable sutures with smaller gauge (5-0 to 6-0)

Leave less scaring

Used for delicate tissue (face, neck)

Nonabsorbable heavy sutures

Used for firmer tissue (chest, abdomen)

110


Suture box

Holds individual packages of sutures

Stamped with an expiration date

Check before removing a suture package

111


Suture package

Labeled with

Type of suture material (e.g., surgical silk)

Size of suture (e.g., 4-0)

Length of suture (e.g., 18 inches)

Date of manufacture

Expiration date of the suture

113


Type and size of suture used

Based on nature and location of tissue sutured

Physician's preference

114

SUTURE NEEDLES

Type of point

Cutting needle: sharp point

Used for firm tissue (e.g., skin)

Noncutting needle: round point

Used for tissues that offer little resistance (e.g., intestines, muscle)

115

SUTURE NEEDLES

Cutting Needles

116

SUTURE NEEDLES

Shape of needle:

Curved needle: can dip in and out of tissue

Needle holder must be used

Straight needle: used when tissue can be displaced to permit needle to be

pushed and pulled through tissue

Does not require needle holder

117

SUTURE NEEDLES

118

SUTURE NEEDLES

Design of needle

Eyed needle: has eye through which suture is inserted

Swaged needle: suture and needle are one continuous unit. Advantages:

Suture does not slip off needle

Tissue trauma is reduced (only one strand of suture is pulled through tissue)

119

SUTURE NEEDLES

120

INSERTION OF SUTURES

Provide patient with written instructions on wound care

Instruct patient when to return for removal of sutures

132

SUTURE REMOVAL

When wound healed: no longer needs support of sutures

Length of time sutures remain in place depends on

Location of the sutures

Amount of healing that must occur

133

SUTURE REMOVAL

Face and neck

Have a good blood supply: area heals more rapidly

Sutures usually removed in 3 to 5 days

Chest, arms, legs, hands, and feet

Sutures usually removed in 7 to 10 days

134

SURGICAL SKIN STAPLES

Fastest method for closing long skin incisions

Trauma to tissue is reduced

Tissue does not have to be handled very much during insertion

Consist of stainless steel

135


Inserted into skin with a special skin stapler

Reusable and disposable available

Holds cartridge with a prescribed number and size of staples

136


Physician inserts staples

Tissue is first approximated with tissue forceps

Stapler held over the site

Staple inserted into the skin

137


Are easily removed with a special staple remover

MA is usually responsible for removing staples

Written or verbal order must be given by physician

138

ADHESIVE SKIN CLOSURES

Approximate the edges of a laceration or incision

Consist of sterile, hypoallergenic tape

Available in a variety of widths and lengths

139


Brand names: Steri-Strip; Proxi-Strip

140


Used when not much tension exists on skin edges

Applied transversely across line of incision

To approximate edges of wound

141


Advantages

Sutures and local anesthetic are not needed

Can be easily applied and removed

Lower incidence of wound infection compared with sutures

Results in less scarring than sutures

142


143


Disadvantages:

Less precision in bringing wound edges together

Cannot be used where adhesive has difficulty adhering to skin

Areas that harbor moisture – palms of hands; soles of feet; axilla

Hairy areas – scalp; chest of male patient

144


MA is frequently responsible for applying and removing

5 to 10 days after application: closures may spontaneously lift off

If removal is required: MA should follow proper procedure

145

in the minor office surgery procedures.

Lesson 25.3

148

TRAY SETUP

MA must:

Know instruments/supplies for each setup

Know type of assistance required by physician

Be able to work quickly and efficiently

Be able to anticipate physician's needs

149

TRAY SETUP

Instruments/supplies are set on a sterile field

Many offices maintain index cards indicating

Instruments/supplies for each MOS

Skin preparation

Patient position

Physician's glove size

Type of suture material

Preoperative and postoperative instructions

150

TRAY SETUP

Tray can be set up before or after preparing patient's skin

Do not allow sterile setup to become contaminated:

If must turn away or leave the room:

Place sterile towel over tray

151

TRAY SETUP

Covering Sterile Tray

152

METHODS USED TO SET UP A STERILE TRAY

Prepackaged sterile setups

Commonly used

Setup wrapped in

Disposable sterilization paper

Muslin (prepared through autoclave sterilization)

Labeled according to use (e.g., suture pack)

153


Prepackaged sterile setups

Contains most of the instruments/supplies required for the MOS

Package opened on flat surface (e.g., Mayo tray)

Inside of wrapper used as sterile field

Add additional articles if needed (e.g., 4 x 4 gauze, sutures)

154


155


Place articles on a sterile field individually

Place sterile towel over a tray

To prevent contamination: handle towel by corners; do not fan towel through

air

Flip articles onto field from peel-apart packages

156


157

SIDE TABLE

Articles that are not sterile must not be placed on the sterile field

Set on an adjacent table or counter

158

SIDE TABLE

Examples:

Surgical scrub brush

Vial of local anesthetic

Physician's sterile gloves (outside of wrapper is not sterile)

159

SKIN PREPARATION

Skin contains an abundance of microorganisms

If microorganisms enter operative site: could cause wound infection

Operative site must be cleaned and prepared

Remove as many microorganisms as possible

Reduces risk of surgical wound contamination

160

SKIN PREPARATION

Shaving the site

Hair supports growth of microorganisms

Skin may need to be shaved around operative site

Disposable shave preparation trays are available

Pull skin taut to prevent nicks

When shaved, rinse and dry area thoroughly

161

SKIN PREPARATION

Cleansing the site

Cleanse with antiseptic solution

Example: Betadine Surgical scrub)

162

SKIN PREPARATION

Cleansing the site

Scrub site with surgical scrub brush

Use circular motion: moving from inside outward

Rinse using gauze pads saturated with water

Blot dry with sterile gauze

163

SKIN PREPARATION

Cleansing the Site

164

SKIN PREPARATION

Antiseptic application

Decreases the number of microorganisms

Betadine commonly used

165

SKIN PREPARATION

Fenestrated drape applied

Opening placed directly over operative site

Provides sterile area around operative site

Decreases contamination of the surgical wound

166

SKIN PREPARATION

Fenestrated Drape

167

LOCAL ANESTHETIC

Most frequently used:

Lidocaine hydrochloride (Xylocaine)

168

LOCAL ANESTHETIC

Local anesthetic injected around the operative site (infiltration)

Produces a loss of sensation

Prevents patient from feeling pain during surgery

When first injected:

Causes brief burning sensation

Begins working: 5 to 15 minutes

169

LOCAL ANESTHETIC

Duration of action: 1 to 3 hours

Local anesthetic containing epinephrine may be ordered

Epinephrine: Prolongs effect of anesthetic and decreases rate of systemic

absorption

By constricting blood vessel at the operative site

Physician informs MA of type, strength, and amount of anesthetic required

Example: 1 ml of Xylocaine 2.0% with epinephrine

170

PREPARING THE ANESTHETIC

Cleanse vial with alcohol wipe

Methods to draw anesthetic into syringe

Method 1: MA draws anesthetic up and hands it to physician, who has not yet

applied sterile gloves

Physician injects anesthetic and then applies sterile gloves

171


Methods to draw anesthetic into syringe

Method 2: Physician draws up with sterile gloved hands

Show label of vial to physician

Hold vial while physician withdraws medication – vial is medically aseptic

and cannot be touched by physician's sterile gloved hands

172


If MA draws up: needle and syringe placed on side table

If physician draws up: needle and syringe placed on sterile field

173

ASSISTING THE PHYSICIAN

Type of assisting required based on

Type of surgery

Physician's preference

174


MA may apply sterile gloves and assist directly

Hand instrument to physician:

In a firm, confident manner – so it does not slip out of physician's hand

In its functional position (position in which it is to be used)

175


Handing Instrument

176


Add instruments and supplies to sterile field as needed

Tissue specimen may be obtained and sent to the laboratory

Specimen must be placed in appropriate-sized container

177


Holding Specimen Container

178



Label specimen container

Using two unique identifiers – information that clearly identifies a specific

patient: patient’s name; patient’s date of birth

179



Label specimen container

Computerized bar code label

Handwriting information on label, which includes patient’s name, date of

birth, date and time of collection, medical assistant’s initials

Complete biopsy request form

180


Biopsy Request Form

181


Once minor office surgery is completed

Physician may instruct MA to place dry sterile dressing over site

Protects wound from contamination or injury

Absorbs drainage

MA responsible for assisting patient and cleaning the examination room

182

SEBACEOUS CYST REMOVAL

Sebaceous cyst: Thin, closed sac or capsule located just under surface of

the skin

Forms when outlet of gland becomes obstructed

Contains sebum (secretions from the sebaceous gland)

Causes swelling

183


Lining of cyst

SURGICAL INCISION AND DRAINAGE OF

LOCALIZED INFECTIONS

Abscess: Collection of pus in a cavity surrounded by inflamed tissue

195



Abscess: Collection of pus in a cavity surrounded by inflamed tissue

Caused by pathogen that invades tissues

Usually by way of break in the skin

Serves as defense mechanism to keep infection localized

By walling off microorganisms – prevents them from spreading through the

body

196



Furuncle (boil): Localized staphylococcal infection that originates deep

within a hair follicle

Produces pain and itching

Skin becomes red

Turns white and necrotic over the top

Surrounded by erythema and induration

Moles can occur anywhere on skin

Normal: Between 10 and 40 moles on body

Usually concentrated on back, chest, and arms

Usually benign

202

MOLE REMOVAL

Characteristics of moles

Range from brown to nearly black in color

Can also be pinkish flesh color to dark blue or even black

Dark-colored moles: consist of melanocytes – melanocytes: produce the

pigment melanin (responsible for dark color of moles)

203

MOLE REMOVAL

Characteristics of moles

Shape is usually round or oval

May be smooth or rough

Size: usually smaller than a pencil eraser

Melanoma

Very serious type of skin cancer

Can sometimes develop within a mole

Most apt to be found

Upper backs of men

Lower legs of women

211

MOLE REMOVAL

Melanoma

Excessive sun exposure increases risk of developing certain melanomas

Especially severe blistering sunburns early in life

If discovered early

May be possible to completely remove melanoma – reduce the spread of

skin cancer; if left untreated: can be fatal

212

MOLE REMOVAL

Melanoma

Characteristics of melanoma:

Asymmetrical: one-half of the mole is different from the other half

213

MOLE REMOVAL

Melanoma


Irregular border: the edges of the mole are notched, uneven, or blurred;

rather than round or distinct

214

MOLE REMOVAL

Melanoma


Color varies from one area of the mole to another – various shades of tan,

brown, and black (and sometimes white, red, or blue) are present

215

location)

Biopsy may be taken prior to removal

218

PROCEDURE: MOLE SHAVE EXCISION

Most commonly used to remove protruding moles

Can also be used to remove skin tags

Not used to remove dysplastic nevi

Might leave mole cells beneath the surface of the skin

Could cause mole to grow back again

219


Sutures not generally required

After numbing effect of anesthetic wears off

Area will be tender and sore

As healing occurs: scab forms

Falls off within 1 to 2 weeks (leaves a red mark)

As healing progresses

Flat white mark usually remains (same size as mole)

Over time: fades to a barely visible scar

220


Physician numbs area with a local anesthetic

Physician uses a scalpel to shave off protruding part of mole

Until area is flush with level of surrounding skin

Electrocautery instrument used to:

Destroy tissue below the surface of mole

Control bleeding

221


Topical antibiotic applied to area

INGROWN TOENAIL REMOVAL

Occurs when toenail grows deeply into nail groove and penetrates

surrounding skin

Results in pain and discomfort

237


Caused by:

External pressure from tight shoes

Trauma

Improper nail trimming

Infection

238


Protruding nail: acts as a foreign body

Usually results in secondary infection

colposcope

Colposcope: Lighted instrument with a magnifying lens

Used to examine the vagina and cervix

249

COLPOSCOPY

Purpose

Examine vagina and cervix for abnormal tissue growth

When performed

After abnormal Pap test results

To evaluate vaginal or cervical lesion observed during a pelvic examination

250

COLPOSCOPY

Normal and Abnormal Cervix

251

COLPOSCOPY

Primary goal

Prevent cervical cancer

By detecting precancerous lesions early – then you can treat them

Procedure performed 1 week after end of menstrual period

Rationale: blood cells make it difficult to view cervix

252

COLPOSCOPY

Patient Preparation:

Do not douche

Do not use tampons, vaginal medications, spermicides

Do not have intercourse for 24 hours before procedure

253

COLPOSCOPY

Lens positioned 12 inches from opening of vagina

Magnifies tissue, which facilitates:

Inspection of cervical cells

Obtaining a biopsy specimen

Magnification of 6x to 15x generally used

254

PROCEDURE: COLPOSCOPY

Physician inserts vaginal speculum

255


Applicator moistened with saline used to wipe cervix:

Removes mucus film

Provides for better visualization of cervix

Colposcope focused on cervix

Physician inspects cervix

256


Cervix swabbed with acetic acid

Dissolves cervical mucus and other secretions

Causes abnormal tissue to turn white

Results in easier visualization of abnormal areas of the cervix

257


Cervical epithelium may be stained with Lugol's iodine solution

Healthy epithelium: absorbs iodine

Causes epithelium to stain dark brown color

Abnormal epithelium: unable to absorb iodine

If abnormal area is observed

Cervical biopsy specimen is obtained using punch biopsy forceps

258



259



260

CERVICAL PUNCH BIOPSY

Performed in combination with colposcopy

To remove cervical tissue

For examination by a pathologist

261


Purpose

Detect the presence of cervical dysplasia

Cervical dysplasia: An abnormal growth of cells on the surface of the

cervix that are precancerous: precancerous: Abnormal cells that have the

potential to develop into cancer in the future – can range from mild, to

moderate, to severe

262


Purpose

Detect the presence of cancer of the cervix

Diagnose polyps on the cervix

Diagnose genital warts

May indicate infection with human papillomavirus (HPV) – risk factor for

developing cervical cancer

263


Biopsy helps the physician determine type of abnormal tissue present

Can determine best form of treatment for patient’s condition

Frequently performed following abnormal Pap test results

Majority of abnormal Pap tests are not caused by cervical cancer

Usually caused by a vaginal infection

264


Performed 1 week after end of menstrual period

Cervix is least vascular: prevents inaccurate test results

Patient preparation (begin 2 days before examination)

Do not douche

Do not use vaginal creams, medications, or spermicides

Do not have intercourse for 24 hours before procedure

265

PROCEDURE: CERVICAL PUNCH BIOPSY

Patient put in lithotomy position

266


Anesthetic not needed

Cervix has few pain receptors

Patient experiences either:

No discomfort

Certain amount of discomfort

Ranging from mild to moderate in intensity

Patient may experience

Mild cramping and pinching as specimen is removed

267


Physician inserts vaginal speculum

Cervix is wiped with saline

Then swabbed with acetic acid

Physician may stain cervix with Lugol's solution

Colposcope is focused on cervix and inspected

268


Cervical biopsy punch forceps

CERVICAL CRYOSURGERY

Uses freezing temperatures to treat certain gynecological conditions

Most often performed

Treatment for cervical dysplasia

To destroy abnormal cervical cells that show changes that may lead to

cancer

Performed only after a colposcopy

Confirms presence of cervical dysplasia

Also used to treat chronic cervicitis (inflammation of the cervix)

274


Cryosurgery unit: consists of long metal cryoprobe attached to cooling-

agent tank

Cooling agents

Liquid nitrogen (used most often)

Compressed nitrogen gas

Cryoprobe: inserted into vagina

Placed firmly in contact with the abnormal area

275


Cryosurgery Unit

276


Cooling agents flow through cryoprobe: freezes tissue to –20oC

Causes abnormal cells to die and slough off

Cervical covering eventually is replaced with new, healthy epithelial tissue

Regeneration of cervical tissue: occurs 4 to 6 weeks after procedure

277


Following cryosurgery

Patient required to have Pap test every 3 to 6 months

For a period of time determined by physician

278

PROCEDURE: CERVICAL CRYOSURGERY

Patient placed in lithotomy position

Vaginal speculum is inserted

Cervix swabbed with acid-saline solution

Removes mucus and other contaminants

279


Metal probe inserted into vagina

Place firmly in contact with affected area

Cryosurgery unit turned on

Cooling agent flows through cryoprobe

Causes metal probe to freeze and destroy superficial abnormal cervical tissue

Probe is in contact with cervical area for approximately 3 minutes

Patient may experience pain resembling menstrual cramping

280


Cryoprobe removed for 3 to 5 minutes

Permits cervical temperature to return to normal temperature

Procedure is repeated for another 3 minutes

When completed

Assist patient as needed

Observe for signs of discomfort and vertigo

Patient is given sanitary pad to absorb discharge

281


CRYOSURGERY

Normal activities can be resumed the day following cryosurgery

On first postoperative day

Clear, watery vaginal discharge occurs

Lasts for 2 to 4 weeks

Caused by shedding of dead cervical tissue

Gradually diminishes as healing progresses

282


CRYOSURGERY

Use sanitary pads (rather than tampons)

To absorb the watery discharge

Do not douche, use tampons, or have intercourse

For 2 to 3 weeks following the procedure

Allows for proper healing of cervix

283


CRYOSURGERY

Contact office if any of the following occurs:

Bleeding that is heavier than normal menstrual bleeding

Foul-smelling vaginal discharge

Fever

Lower abdominal pain

Provide patient with written postoperative instructions

Schedule a return visit 6 weeks after procedure

284

SKIN LESIONS

Cryosurgery can be used to remove skin lesions (e.g., warts, skin tags)

Small amount of cooling agent is used

Liquid nitrogen: in small, pressurized canister with attached probe

285

SKIN LESIONS

Liquid nitrogen applied until lesion turns white (indicates freezing of

tissue has occurred)

Patient feels slight burning or stinging

Blister develops and dries to a scab in 7 to 10 days and eventually sloughs

off

Patient should keep area clean and dry until scab sloughs off

Two or more treatments may be required to remove lesion completely

286

BANDAGING

Bandage: Strip of woven material used to wrap or cover a part of the body

Function

Apply pressure to control bleeding

Protect wound from contamination

Hold a dressing in place

Protect, support, or immobilize an injured part of the body

287

GUIDELINES FOR APPLICATION

Apply bandage so that it feels comfortable to patient

Fasten securely with metal clips or adhesive tape

Observe medical asepsis

Area should be clean and dry

288


Do not apply bandage directly over open wound

Apply sterile dressing first to prevent contamination of the wound

Bandage should extend 2 inches beyond edge of dressing

289


To prevent irritation: do not allow skin of two body parts to touch

Insert piece of gauze between body parts (e.g., between fingers)

Pad joints and prominent parts of bones

Prevents bandage from rubbing the skin and causing irritation

290


Bandage body part in its normal position with joints slightly flexed

Avoids muscle strain

Apply bandage from distal to proximal part of the body

Aids in venous return to heart

291


Ask patient if bandage feels comfortable

Should fit snugly so it will not fall off

Not too tightly: impedes circulation

If possible: leave fingers and toes exposed

Circulation can be checked

292


Circulation can be checked

Signs indicating bandage is too tight:

Coldness

Pallor

Numbness

Cyanosis of nail beds

Swelling

Pain

Tingling sensations

293


Ask patient if bandage feels comfortable

If signs occur: loosen bandage immediately

If bandage roll is dropped:

Obtain a new bandage

Begin again

294

TYPES OF BANDAGES
