Repair of injuries

Diagnosis and treatment of certain diseases

3

INTRODUCTION TO MINOR OFFICE SURGERY

Minor Office surgery: Surgical procedure that is restricted to:

The management of minor conditions

Does not require the use of general anesthesia

4

INTRODUCTION TO MINOR OFFICE SURGERY

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

INTRODUCTION TO MINOR OFFICE SURGERY

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

INTRODUCTION TO MINOR OFFICE SURGERY

Minor office surgery performed in a medical office

Insertion of sutures

Sebaceous cyst removal

Incision and drainage of infections

Mole removal

Needle biopsy

7

INTRODUCTION TO MINOR OFFICE SURGERY

Physician explains nature of surgical procedure and risks to patient

Offers to answer questions

8

INTRODUCTION TO MINOR OFFICE SURGERY

MA responsible for

Explaining patient preparation

Obtaining patient's signature on consent to treatment form

9

INTRODUCTION TO MINOR OFFICE SURGERY

Consent to Treatment Form

10

INTRODUCTION TO MINOR OFFICE SURGERY

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

INTRODUCTION TO MINOR OFFICE SURGERY

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

INTRODUCTION TO MINOR OFFICE SURGERY

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

INTRODUCTION TO MINOR OFFICE SURGERY

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

Guidelines to Maintain 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

Guidelines to Maintain 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

Guidelines to Maintain 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

54

CARE OF SURGICAL INSTRUMENTS

Surgical instruments will last for many years if handled and maintained

properly

Care given to an instrument depends on the parts making up the

instrument

Examples: box lock, ratchet, serrations

55

Carefully follow directions to prevent contamination of sterile contents

61

COMMERCIALLY PREPARED STERILE PACKAGES

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

COMMERCIALLY PREPARED STERILE PACKAGES

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

COMMERCIALLY PREPARED STERILE PACKAGES

Opening a Peel-Apart Package

64

COMMERCIALLY PREPARED STERILE PACKAGES

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

COMMERCIALLY PREPARED STERILE PACKAGES

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

COMMERCIALLY PREPARED STERILE PACKAGES

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

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

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

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

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

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

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

STERILE DRESSING CHANGE

Function of a sterile dressing

Protect the wound from contamination and trauma

Absorb drainage

Restrict motion

96

STERILE DRESSING CHANGE

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

Size and location of wound

Amount of drainage

97

STERILE DRESSING CHANGE

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

STERILE DRESSING CHANGE

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

SUTURE SIZE AND PACKAGING

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

113

SUTURE SIZE AND PACKAGING

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

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

METHODS USED TO SET UP A STERILE TRAY

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

METHODS USED TO SET UP A STERILE TRAY

155

METHODS USED TO SET UP A STERILE TRAY

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

METHODS USED TO SET UP A STERILE TRAY

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
