Perioperative Nursing
Definition of Surgery
Surgery is any procedure
performed on the human body
that uses instruments to alter
tissue or organ integrity.
Purposes of Surgery
Diagnostic
 Curative
 Restorative
 Palliative surgery, which makes the
client more comfortable
 Cosmetic surgery, which
reconstructs the skin and
underlying structures

Perioperative Nursing
Types of Surgery
Degree of urgency – necessity to preserve the
client’s life, body part, or body function.
 Degree of risk – involved in surgical
procedure is affected by the client’s age,
general health, nutritional status, use of
medications, and mental status.
 Extent of surgery – Simple and radical

Perioperative Nursing
Types of Surgery (Urgency)
Emergency- performed immediately to
preserve function or the life of the client.
 Elective – is performed when surgical
intervention is the preferred treatment for a
condition that is not imminently life
threatening or to improve the client’s life.
 Urgent – Necessary for client’ health to
prevent additional problem from
developing; not necessarily an emergency.
 Required – has to be performed at some
point; can be pre-scheduled.

Perioperative Nursing
Type of Surgery (Degree of Risk)






Major – involves a high degree of risk.
Minor – normally involves little risk.
Age – very young and elder clients are greater surgical
risks than children and adult.
General health- surgery is least risky when the client’s
general health is good.
Nutritional Status – required for normal tissue repair.
Medications – regular use of certain medications can
increase surgical risk.
Mental status – disorder that affect cognitive function


Preoperative Nursing Care
Gerontological Considerations

Cardiovascular
Coronary flow decreases
Heart rate decreases
Response to stress decreases
Peripheral vascular decreases
Cardiac output decreases
Cardiac reserve decreases
Preoperative Nursing Care
Gerontological Considerations
Respiratory System
Static lung volumes decreases
Pulmonary static recoil decreases
Sensitivity of the airway receptors decreases
 Nervous system
Increased incidence of post.op. confusion.
Increased incidence of delirium
Increased sensitivity to anesthetic agents

Preoperative Nursing
Care
Gerontological Considerations
 Renal System
Renal blood flow declines 1.5% per
year. Renal clearance reduced
 Gastrointestinal
Decreased intestinal motility
Decreased liver blood flow
Delayed gastric emptying
Preoperative Nursing
Care
Gerontological Considerations
Musculoskeletal
Decreased mass, tone, strength
Decreased bone density
 Integumentary
Decreased elasticity
Decreased lean body mass
Decreased subcutaneous fat

Laboratory Assessment
Urinalysis
 Blood type and crossmatch
 Complete blood count or hemoglobin
level and hematocrit
 Clotting studies
 Electrolyte levels
 Serum creatinine level
 Pregnancy test
 Chest x-ray examination
 Electrocardiogram

Preoperative Nursing
Consent
Nature and intention of the surgery
 Name and qualifications of the person
performing the surgery.
 Risks, including tissue damage,
disfigurement, or even death
 Chances of success
 Possible alternative measures
 The right of the client to refuse consent or
later withdraw consent.

Deficient Knowledge
Interventions

Informed consent
The surgeon is responsible for obtaining
signed consent before sedation is given and
surgery is performed.
 The nurse’s role is to clarify facts presented
by the physician and dispel myths that the
client or family may have about surgery.

Implementing Dietary
Restrictions
Client is given nothing by mouth
(NPO) for 6 to 8 hours before
surgery.
 NPO status decreases the risk for
aspiration.
 Failure to adhere can result in
cancellation of surgery or increase
the risk for aspiration during or
after surgery.

Administering Regularly
Scheduled Medications

Consult the medical physician and
anesthesia provider for
instructions about drugs, such as
those taken for diabetes, cardiac
disease, glaucoma, regularly
scheduled anticonvulsants,
antihypertensives, anticoagulants,
antidepressants, or corticosteroids.
Intestinal Preparation
Bowel or intestinal preparations are
performed to prevent injury to the
colon and to reduce the number of
intestinal bacteria.
 Enema or laxative may be ordered
by the physician.

Skin Preparation
The skin is the body’s first line of
defense against infection; a break
in the barrier increases the risk for
infection.
 Shower using antiseptic solution.
 Shaving as a procedure before
surgery is viewed as controversial.

Preparing the Client
Possible placement of tubes,
drains, and vascular access
devices
 Teaching about postoperative
procedures and exercises:


Breathing exercises, incentive
spirometry, coughing and splinting
(Continued)
Preparing the Client (Continued)

Leg procedures and exercises,
antiembolism stockings and elastic
wraps, early ambulation, and rangeof-motion exercises
Anxiety Interventions
Preoperative teaching
 Encouraging communication
 Promoting rest
 Using distraction
 Teaching family and significant
others

Preoperative Nursing Care
Anxiety
The nurse must consider the pt’s
family and friends when planning
psychological support.
 Empowering their sense of control.
Activities that decreasing anxiety
are deep breathing, relaxation
exercises, music therapy, massage
and animal-assisted therapy.
 Use of medication to relieve
anxiety.

Preoperative Chart Review
Ensure all documentation,
preoperative procedures, and
orders are complete.
 Check the surgical consent form
and others for completeness.

total loss of sensation, occurring with or without
consciousness.




Blocks transmission of nerve impulses
Suppress reflexes
Promotes muscle relaxation
Controlled level of unconsciousness
Anesthesia
Induced state of partial or total loss
of sensation, occurring with or
without loss of consciousness
 Used to block nerve impulse
transmission, suppress reflexes,
promote muscle relaxation, and, in
some instances, achieve a
controlled level of
unconsciousness

General Anesthesia
Reversible loss of consciousness is
induced by inhibiting neuronal impulses in
several areas of the central nervous
system.
 State can be achieved by a single agent or
a combination of agents.
 Central nervous system is depressed,
resulting in analgesia, amnesia, and
unconsciousness, with loss of muscle
tone and reflexes.

Stages of General Anesthesia
Stage 1: analgesia
 Stage 2: excitement
 Stage 3: operative
 Stage 4: danger

Administration of General
Anesthesia
Inhalation: intake and excretion of
anesthetic gas or vapor to the lungs
through a mask
 Intravenous injection: barbiturates,
ketamine, and propofol through the
blood
 Adjuncts to general anesthetic agents:
hypnotics, opioid analgesics,
neuromuscular blocking agents

Balanced Anesthesia
Combination of intravenous drugs
and inhalation agents used to
obtain specific effects
 Combination used to provide
hypnosis, amnesia, analgesia,
muscle relaxation, and reduced
reflexes with minimal disturbance
of physiologic function

(Continued)
Balanced Anesthesia (Continued)

Example: thiopental for induction,
nitrous oxide for amnesia,
morphine for analgesia, and
pancuronium for muscle relaxation
Complications from General
Anesthesia
Malignant hyperthermia: possible
treatment with dantrolene
 Overdose
 Unrecognized hypoventilation
 Complications of specific
anesthetic agents
 Complications of intubation

Local or Regional Anesthesia
Sensory nerve impulse transmission from a
specific body area or region is briefly
disrupted.
 Motor function may be affected.
 Client remains conscious and able to
follow instructions.
 Gag and cough reflexes remain intact.
 Sedatives, opioid analgesics, or hypnotics
are often used as supplements to reduce
anxiety.

Local Anesthesia
Topical anesthesia
 Local infiltration
 Regional anesthesia

Field block
 Nerve block
 Spinal anesthesia
 Epidural anesthesia

Complications of Local or
Regional Anesthesia
Anaphylaxis
 Incorrect delivery technique
 Systemic absorption
 Overdosage

(Continued)
Complications of Local or
Regional Anesthesia (Continued)

Assess for central nervous system
stimulation, central nervous system
and cardiac depression, restlessness,
excitement, incoherent speech,
headache, blurred vision, metallic
taste, nausea and vomiting, tremors,
seizures, increased pulse, respirations,
and blood pressure.
Treatment of Complications
Establish an open airway.
 Give oxygen.
 Notify the surgeon.
 Fast-acting barbiturate is usual
treatment.
 If toxic reaction is untreated,
unconsciousness, hypotension,
apnea, cardiac arrest, and death
may result.

Conscious Sedation
IV delivery of sedative, hypnotic, and
opioid drugs reduces the level of
consciousness but allows the client to
maintain a patent airway and to respond
to verbal commands.
 Diazepam, midazolam, meperidine,
fentanyl, alfentanil, and morphine
sulphate are the most commonly used
drugs.

(Continued)
Conscious Sedation (Continued)

Nursing assessment of airway,
level of consciousness, oxygen
saturation, electrocardiographic
status, and vital signs are
monitored every 15 to 30 minutes.
Collaborative Management
Assessment

circulation, respiration, and nerve
conduction
Impaired Skin Integrity and
Impaired Tissue Integrity
Interventions include:

anesthesia provider
Interventions for
Postoperative
Clients
Francisco Felix
PACU Recovery Room
Purpose is to provide ongoing
evaluation and stabilization of clients to
anticipate, prevent, and treat
complications after surgery.
 PACU is usually located close to the
surgical suite.
 The PACU nurse is skilled in the care of
clients with multiple medical and
surgical problems that can occur
following a surgical procedure.

Collaborative Management
Assessment
 Physical assessment and clinical
manifestations

Assess respiration.
 Examine surgical area for bleeding
 Monitor vital signs.
 Assess for readiness to discharge
once
criteria have been met.

Respiratory System
Airway assessment
 Breath sounds
 Other respiratory assessments

Cardiovascular Assessment
Vital signs
 Cardiac monitoring
 Peripheral vascular assessment

Neurologic System
Cerebral functioning
 Motor and sensory assessment important
after epidural or spinal anesthesia

Motor function: simple commands; client
to move extremities
 Return of sympathetic nervous system
tone: gradually elevate head and monitor
for hypotension

Fluid, Electrolyte, and AcidBase Balance
Check fluid and electrolyte balance.
 Make hydration assessment.
 Intravenous fluid intake should be
recorded.
 Assess acid-base balance.

Renal/Urinary System
The effects of drugs, anesthetic agents,
or manipulation during surgery can
cause urine retention.
 Assess for bladder distention.
 Consider other sources of output such
as sweat, vomitus, or diarrhea stools.
 Report a urine output of < 30 mL/hr.

Gastrointestinal System
Nausea and vomiting are common
reactions after surgery.
 Peristalsis may be delayed because
of long anesthesia time, the
amount of bowel handling during
surgery, and opioid analgesic use.
 Clients who have abdominal
surgery often have decreased
peristalsis for at least 24 hours.

Nasogastric Tube Drainage

Tube may be inserted during surgery to
decompress and drain the stomach, to
promote gastrointestinal rest, to allow
the lower gastrointestinal tract to heal,
to provide an enteral feeding route, to
monitor any gastric bleeding, and to
prevent intestinal obstruction.
(Continued)
Nasogastric Tube
Drainage (Continued)
Assess drained material every 8
hours.
 Do not move or irrigate the tube
after gastric surgery without an
order from the surgeon.

Skin Assessment
Normal wound healing
 Ineffective wound healing: can be seen
most often between the 5th and 10th days
after surgery


Dehiscence: a partial or complete
separation of the outer wound layers,
sometimes described as a “splitting open
of the wound.”
(Continued)
Skin Assessment (Continued)


Evisceration: a total separation of
all wound layers and protrusion of
internal organs through the open
wound.
Dressings and drains, including
casts and plastic bandages, must
be assessed for bleeding or other
drainage on admission to the PACU
and hourly thereafter.
Postoperative Phase
Discomfort/Pain Assessment
Client almost always has pain or
discomfort after surgery.
 Pain assessment is started by the
postanesthesia care unit nurse.
 Pain usually reaches its peak the
second day after surgery, when the
client is more awake, more active,
and the anesthetic agents and
drugs given during surgery have
been excreted.

Impaired Gas Exchange
Interventions include:
 Airway maintenance
 Positioning the client in a side-lying
position or turning his or her head to the
side to prevent aspiration
 Encouraging breathing exercises
 Encouraging mobilization as soon as
possible to help remove secretions and
promote lung expansion
Impaired Skin Integrity
Interventions include:
 Nursing assessment of the surgical area
 Dressings: first dressing change usually
performed by surgeon
 Drains: provide an exit route for air, blood,
and bile as well as help prevent deep
infections and abscess formation during
healing
(Continued)
Impaired Skin Integrity
(Continued)
Drug therapy including antibiotics
and irrigations are used to treat
wound infection.
 Surgical management is required
for wound opening.

Acute Pain
Interventions include:
 Drug therapy
 Complementary and alternative
therapies such as:
Positioning
 Massage
 Relaxation and diversion
techniques

Potential for Hypoxemia
Interventions include:
 Maintenance of airway patency and
breathing pattern
 Prevention of hypothermia
 Maintenance of oxygen therapy as
prescribed
Health Teaching
Prevention of infection
 Dressing care
 Nutrition
 Pain medication management
 Progressive increase in activity
level
 Use of proper body mechanics

