BY: Diana Blum RN MSN Metro Community College OR Experience BY: Diana Blum RN MSN Metro Community College In 2009, which are the latest statistics I could find… figures show that: Total number of inpatient procedures performed: 48.0 million Cardiac catheterizations: 1.1 million Coronary artery bypass graft: 415,000

Preoperative Begins with the scheduling of procedure Ends at time of transfer to surgical suite Places emphasis on safety and client education The client’s readiness is critical to the outcome Includes education and intervention to reduce anxiety and complications, and to promote cooperation Communication and collaboration with the surgical team is essential to reach desired outcome http://www.youtube.com/watch?v=of-y32jBZl4 Baseline testing may me done here or prior to surgery day. Consent needs obtained before anesthesia is delivered.

Procedures Categorized by: Reason for procedure Urgency of the procedure Degree of risk Anatomic location GUIDELINES ON P.587

Types of Surgery Cosmetic Palliative Reconstructive Elective Urgent Emergent Curative Exploratory Diagnostic Cosmetic is performed to enhance appearance. Palliative is done for symptom alleviation. Reconstructive is to rebuild tissue.---can anyone give an example of this that was in news over the past couple of years? New face, girl walks in propellar. Elective is one that is scheduled for a non acute problem Urgent is one that needs complete in a given time frame usually within 48 hours Emergent is one that entails life or death Curative obviously affects a cure for ailment Exploratory is done to look around and determine next path to take Diagnostic is done to confirm a dx. If you are unsure of surgical suffixes look at pg 588.

Surgical Areas Preoperative holding area Quiet, calm transition Equipment includes: 02, EKG machine, BP cuff, code cart RN verifies that all relevant tests and documentation are completed prior to surgery Abnormals reported to MD Confirm NPO status NPO needs confirmed on arrival to facility. It could postpone a surgery. MAKE sure they void right before surgery!!!

ASSESSMENT Preoperative health evaluation 30 days before surgery, must be documented, clears pt for surgery Pre op history and physical exam Done by anesthesia provider ASA classification, done with any type of sedation (pg 589) Preop assess may be done 1 week before… tour or area , ekgs, lab, blood typing, etc Baseline vitals are HUGE Nutrition is also big because of the healing process post op.

Risk Factors Elderly Obesity Diabetes Heart conditions Renal failure Dm increases heart risk and infection risk RF increases heart risk and f/e Elderly/copd/smokers have increased risk of atelectasis and pneumonia.

Assessment History Physical Psychosocial Laboratory Radiographic Age, drug/ETOH use, meds, alternative meds, medical hx, surgery hx, anesthesia experiences, blood donations, allergies, family hx, type of surgery planned, education recv’d about perioperative period, support system Physical important to obtain baseline assessment, complete vitals, report abnormal findings to doctor Psychosocial Looks at anxiety level, coping ability, and support system Anxiety and fear may influence the amount and type of anesthesia and affect ability to learn, cope, and cooperate Laboratory Provides a baseline for the client Helps predict potential complications Radiographic Provides baseline and looks at size & shape of heart and lungs Diagnostics EKG- used as baseline. Looks for old MI, or other complications that could postpone surgery Again LOOK FOR ABNORMALS they can hold up a surgery…BP issues, Dysrhymias, +UA Why would ETOH use be important to know? It thins the blood Why are drugs important? They affect metabolism and what can be given Why herbal meds? They can affect a number of things for example fish oil thins the blood.

Example of preop form

Question Which diuretic can cause problems in surgery? A. lasix B. hydrochlorothiazide C. valium D. benadryl

Lasix and hydrochlorothiazide may cause excessive respiratory depression resulting from an associated electrolyte imbalance What electrolytes? Potassium and sodium

Nursing Diagnosis Disturbed sleep pattern r/t anxiety Ineffective coping r/t impending surgery Anticipatory grieving r/t effects of surgery Disturbed body image r/t anticipated changes Powerlessness r/t health care environment, loss of independence Here are some nursing diagnoses for the preop period this is not an exclusive list. Others can apply as well.

Education Doctor should explain purpose and expected results of surgery Consent needs to be obtained prior to surgery. (if pt signs with an ‘X’ 2 witnesses must sign. Client should ask questions if they don’t understand a term or procedure NPO requirements needs to be explained Preoperative preparations need to be explained (colon prep, or skin prep) Client should understand post op exercises and techniques prior to surgery—I.S., etc. Education is KEY. The more informed the less anxious they usually feel. Always keep cultural considerations in check see pg 598 for a discussion on those.

Informed Consent must be done prior to surgery Procedure, risks and benefits need to be explained to the patient by the SURGEON The patient must be competent to understand information Consent for blood Consent for anesthesia is separate Pg 608. Consent is usually good for 24-48 hours depending on the facility. If they sign with a X then 2 witnesses must sign. Poa or guardian may also sign if pt unable. If you get phone consent 2 people need to witness. If life or death consent may be waived.

Legal Responsibilities DNR DNI Must be clearly documented Know your facility protocol.. Some facilities have it that they can be DNR on floor but not in OR. Write NO on site not being operated on and yes on the correct site.

Surgical Prep Bowel prep Skin prep-shower, hair removal (clippers) (see pg 610) Preoperative meds Antibiotic Bowel: done for abd surgery to decrease intestinal bacteria laxatives 1-2 days before low residue diet several days before, antibx, enemas nite before Skin prep: CHG baths nite before and morning of to rinse off bacteria Preop meds: antibx for infection prevention Antianxiety to help relax NPO to decrease aspiration

Tubes, drains, vascular access Pt must be educated prior to surgery Reduces fear Tubes Foley- monitors renal function NG-used for abd surgery to decompress the stomach Drains Removes fluid for surgical site. CT, JP, Hemovac, Orthopat Vascular access For anesthesia For drugs and fluids

Respiratory education Incentive spirometry Encourages clients to take deep breaths every 1-2 hours after surgery Usually 10x’s per hour or with each commercial break from a TV show Deep breathing Sit upright, feet firm on ground, gentle breath through mouth, exhale gently Expansion breathing Comfortable upright position, knees slightly bent, place hands on each side just above waist Splinting use pillow or towel and place over surgical site, take 3 deep breaths and clear then cough to loosen secretions See chart 18-4 for more thorough instruction

DVT risk Obese >40 yrs old Have cancer Immobile or decreased mobility Leg fracture or trauma History of DVT, PE, Varicose veins, or edema Use oral contraceptives Smoke Decreased cardiac output Get them antiembolism stockings The clients with these have increased risk of SVT why? Venous stasis is the answer. That is why ted hose are worn and in or they are usually thigh highs.

Aka “sexy socks”

Anxiety reduction Distraction Promote rest Guided imagery What is guided imagery? Have the pt close their eyes and imagine something that would appeal to them. Like the beach, a concert, etc. Also help to foster open ended questions.

Gerontological Considerations Go over instructions slower Have family present Co-existing disease increases risk Positioning The coexisting conditions make the surgery riskier Why is positioning important? Easier to get to surg site, puts at injury risk Culturally what can we do? get interpretor, work around worship time if able, face bed toward mecca if able, respect beliefs.

Intra op Urinary retention is a problem post op in some surgeries so we need to plan accordingly in the preop arena.

Nursing diagnosis Risk for infection Impaired skin integrity Altered body temperature Anxiety Injury related to positioning and other hazards

Members Surgeon heads surgical team Makes decisions related to surgical procedure May need assistant Surgical assistant (other doctor, surgical tech, resident, intern) May hold retractors, suction wound, cut tissue, suture, and dress wounds depending on scope of practice and under supervision of physician Anesthesia Anesthesiologist or Certified Registered Nurse Anesthestist Maintains airway Monitoring circulation/respiratory status Replace blood/fluid loss

OR nurses Holding area nurse Primary role is Circulating Nurse Duties performed outside of sterile field Scrub Nurse Passes instruments, sponges in the sterile field Perform surgical scrub Very specialized role, most education is during orientation, not in nursing school.

Surgical Areas Operating Room Restricted area Trend towards less invasive procedures (less scarring, quicker recovery, decreased length of hospitalization

Basic Guidelines for Surgical Asepsis All materials in contact with the wound and within the sterile field must be sterile. Gowns are sterile in the front from chest to the level of the sterile field, and sleeves from 2 inches above the elbow to the cuff. Only the top of a draped table is considered sterile. Items are dispensed by strategically to maintain sterility. Movements of the surgical team are from sterile to sterile and from unsterile to sterile only.

Movement around the sterile field must not cause contamination of the field. At least a 1-foot distance from the sterile field must be maintained. Whenever a sterile barrier is breached, the area is considered contaminated. Every sterile field is constantly maintained and monitored. Items of doubtful sterility are considered unsterile. Sterile fields are prepared as close as possible to time of use. http://www.youtube.com/watch?v=EvpcGmExsd4&feat ure=related

Question true or false. To maintain surgical asepsis, the nurse knows that the sides and top of a draped table is considered sterile.

Answer False. Rationale: Sterile drapes are used to create a sterile field. Only the top surface of a draped table is considered sterile. During draping of a table or patient, the sterile drape is held well above the surface to be covered and is positioned from front to back.

Infection Anyone with open wound, cold, or any infection should not participate in surgery Jewelry should be minimal Hands of surgical staff are usually cultured every 3-6 months to determine possible nosocomial (hospital acquired) infections Like what---staph or strep

Time out procedure Nurse asks pt to confirm procedure and is verified with consent form Patient verifies the right site and surgeon 2 patient identifiers Site mark “Time out” Name, procedure, site, document See pg. 612

Anesthesia http://www.youtube.com/watch?v=WOrjcLJ2IE 0&NR=1

Anesthesia Def: induced state of partial or total loss of sensation, occurring with or without loss of consciousness. Purpose: block nerve impulse transmission, suppress reflexes, promote muscle relaxation, and sometimes achieve controlled level of unconsciousness Choice depends on: type and duration of procedure, area of body, safety issues, emergency, pain management after surgery, last meal or liquids or drugs TABLE ON PAGES 626-629

General Definition: reversible loss of consciousness induced by inhibiting neuronal impulses in several areas of the central nervous system Depress CNS Results in analgesia (pain relief), amnesia (memory loss), and unconsciousness with loss of muscle tone and reflexes Used in head, neck, upper torso and abd surgeries

Stages of general 1:sedation administered Induction and LOC, decreased sensation Warmth, dizziness, noises exaggerated 2: excitement/delirium LOC and relaxation, regular breathing Pupils dilate, HR increases, may need to restrain pt Do not touch pt 3: operative anesthesia Muscle relaxation, depressed vitals Unconscious, maintained for hours 4:danger = Medullary Depression Depressed vs, respiratory failure Too much anesthesia, cyanosis Emergence: recovery from anesthesia

Types of general Inhalation: most controllable Fast acting Passes through vaporizer Depresses CNS Ex: Nitrous Oxide

IV: rapid and pleasant Induce and maintain anesthesia Anesthetics Opiods Etomidate Fentanyl Valium Morphine Versed Diprivan Reversal agent for opoids=Narcan (0.2mg) Reversal agent for Benzos = Romazicon(0.2mg)

Muscle relaxants Affect skeletal muscle Administered before intubation Assess with nerve stimulator Succinylcholine, Tracrium, Vecronium Reversal agent= Neostigmine (0.5-2mg

Balanced: minimal disturbance to function, used with elderly and high risk Regional (Spinal, Epidural, Peripheral nerve block)~ gag and cough stay intact block transmission of sensory impulses Does not depress respirations Local injection of med With balanced smaller doses are used. Complications of regional: HA Hypotension Meningitis Hematoma at site Nerve damage

Types of Regional Anesthesia Spinal Local anesthetic injected into subarachoid space, directly into CSF “Blocks” at level of spinal cord (sensory and motor) Epidural Local anesthetic into epidural space Peripheral nerve block Anesthesia of a certain area No systemic effect

Intraoperative Complications Nausea and vomiting Anaphylaxis Hypoxia and respiratory complications Hypothermia Dysrhymias Malignant hyperthermia Disseminated intravascular coagulation (DIC) Anaphylaxis allergy to substance Hypoxia= decreased sats compromised lung sounds Hypotherm. Is decreased temp Malignant hyper…muscle disorder genetically transferred. Temp >104, tachy low bp

Malignant Hyperthermia Life threatening Predisposition is genetic causes increased calcium and potassium levels in skeletal muscles Immediate reaction or several hours later s/s: tachycardia, dysrhythmias, muscle rigidity (jaw, face), hypotension, tachypnea, mottling, cyanosis, myoglobournia (muscle proteins in urine), *increase in CO2 and decrease sat Care: stop agent, intubate, give dantrium to reverse, check ABG, cooling techniques, monitor core temp, EKGs, insert foley, hydrate, ICU for at least 24 hours Chart 26-3

Manifestations Hypoxia Hyperthermia****THIS IS A LATE SIGN**** Dysrhythmias Hypotension Early signs: contracture of jaw Sinus tach Increase in expiratory CO2 *Pg. 630 *

Complications continued Overdose: can occur if metabolism and drug elimination are slower (ht, wt, and allergies are vital to know before administration) Unrecognized hypoventilation: failure to exchange gases can lead to cardiac arrest, permanent brain damage, and death. Vital to use end tidal carbon dioxide monitor to confirm the exchange

Intubation complication Broken or chipped teeth Swollen lip Vocal cord trauma

Question Malignant hyperthermia usually manifests within what time frame after induction of anesthesia? 5 minutes 10–20 minutes 30 minutes 45 minutes

Answer 10–20 minutes Rationale: Malignant hyperthermia usually manifests about 10 to 20 minutes after induction of anesthesia. It can also occur during the first 24 hours after surgery.

Local Numbing agent is used Mentally alert Complications: potential cardiac depression, toxic reaction, edema, blurred vision, inflammation, etc. see Provides a numbing sensation to the site of interest like with pacemakers and stitches.

Types of local Topical Infiltration: directly into wound or lesion Blocks: Field: injections around work site (lidocaine, novocaine) Nerve: injection into or around nerve in involved area- used for chronic pain relief Spinal: injection of agent into CSF in the subarachnoid space-absorbed rapidly Epidural: placed in epidural space-may affect breathing Example of topical is tetracaine Infiltration example is novocaine Nerve is done for shoulder surg Epidural for ob stuff

Moderate (Conscious) Sedation Minimally depressed LOC Pt able to maintain airway Pt responds to physical and verbal stimuli Twilight or translike Quickly recovers

Moderate (Conscious) Sedation As a nurse, what do you need to have available at the bedside? What medications might be given? What monitoring/assessments? What types of procedures? #1 airway tele #2 versed fentanyl #3 airway vs #4 colonoscopy egd tee

Potential Adverse Effects of Surgery and Anesthesia Allergic reactions or drug toxicity Cardiac dysrhythmias Over sedation or Under sedation Trauma: laryngeal, oral, nerve, and skin, including burns Hypotension Thrombosis See Chart 19-1 http://www.youtube.com/watch?v=7MZ qB4EWlZg Anesthesia awareness: they feel everything but cant move

Gerontologic Considerations Elderly patients are at increased risk for complications because of: Pre-existing conditions. Aging heart and pulmonary systems. Decreased homeostatic mechanisms. Changes in responses to drugs because of changes such as decreased renal function, etc.

Nursing diagnosis Risk for injury r/t positioning Impaired skin integrity r/t surgical incision Risk for infection

Important to remember Always know client’s wishes about life sustaining measures because they apply in the OR as well However some facilities/doctors require that the surgical client that is DNR on unit is full code in OR. Always know the allergies and reactions Always know current lab values because they could postpone surgery Know the client’ s baseline vitals to monitor for complications Patient identification Correct informed consent Verification of records of health history and exam Safety measures such as grounding of equipment, restraints, and not leaving a sedated patient Verification and accessibility of blood

Positioning Accommodates access Surgical view Maintain skin integrity (pressure ulcers) Injury to nerves may happen Prevent injury Complications: Compromised respiratory status, pressure ulcers, injury to nerves

Surgical positions Supine Trendelenburg Prone Lateral Jackknife lithotomy

Bariatrics Deals with causes, prevention, and treatment of obesity First line: diet, exercise, behavior therapy, & antiobesity drugs BUT HAS ONLY SHORT TERM SUCCESS IN MANY CASES

Antiobesity drugs: Orlistat (approved Feb ’07) - reduces absorption of fat by inhibiting pancreatic lipase Metformin Byetta (delays gastric emptying)

Bariatric Surgery Roux en Y: most commonly performed - least likely to result in nutritional deficiencies - small bowel is divided & arranged into a “y” and attached to the small stomach pouch - pt feels fullness rapidly after eating

Post op Starts at the completion of surgery and transfer to PACU or ICU Stabilize VS, maintain airway Prepare pt for discharge To work here in-depth knowledge of the following areas needed: pharm, pain management, and procedures, good assessment skills, decision maker in critical situations

Assessment Cardio Telemetry, ekgs, vitals, pulses, homans, Neuro LOC, motor response, orientation, arousal Fluid and electrolyte I/O, hydration, IVF, acid base Renal Output, urine retention is common if no foley Gi N/V, peristalsis, monitor for ileus, NG tube output if indicated Skin Monitor wound, drainage, drains, dressings, Vitals are vital Usually q15” x4, q30” x4, q1hr x4, q2hr x4, then q4hr Respiratory status Airway management, lung sounds, muscle use, snoring, stridor (high pitched crowing) Monitor PAIN Laryngospasms could occur causing aireway to be closed—open it sxn it 02 intubate etc

Early infection can be indicated on increase in band cells of the WBC differential (left shift) Get culture Notify MD Monitor ABGs and CMP What does the shift mean? there is an increase in immature blood cells. This happens to attemp to ward off a active infection. Think of it like a bird the mama is kicking the babies out of the nest before it is time.

Aldrete Post Anesthesia Recovery Score (PARS) Numerical scoring system to eval PACU patients Based on activity, Respirations, Circulation, Consciousness, O2 Sats Ranges from 0 to 10, 10 is the best Score when arrives in PACU, every 30 min until 8 or higher is achieved Score also done at discharge

Nursing diagnosis

Impaired Gas Exchange Open airway Breathing pattern improved over baseline Adequate O2 saturation Provide supplemental oxygen Artificial airway if patient is minimally responsive Cough deep breath, IS

Risk for Imbalanced Fluid Volume Adequate hemostasis Normal fluid and electrolyte balance Monitor hourly for postop bleeding Mark drainage on dressing, monitor for enlargement Monitor for possible drainage beneath patient Monitor for internal bleeding Monitor for signs of dehydration, fluid overload

Risk for Decreased Cardiac Output Rhythm, cardiac output BP, heart rate consistent with baseline Monitor for sinus tachycardia/bradycardia, identify and treat cause Monitor for hypotension; IV fluids, patient positioning Monitor for hypertension, identify and treat cause

Risk for Imbalanced Body Temperature: Hypothermia Normal core temperature Monitor for core temperature <36°C (96.8°F), shivering, patient report of feeling cold Risk factors: patient history, length of surgery, cold solutions Blankets, clothing, ambient temp Treat with active warming, meds

Pain Physiological and psychological effects Delayed ambulation, diminished functioning Monitor for pain management and respiratory depression PCA, PCEA: monitor for pain relief, untoward effects Monitor sensory level of the epidural

Anxiety Can increase morbidity and mortality, length of stay Affects VS, depresses immune system, delays healing Implicated in heart problems, postop pain Individualized care plan based on patient preferences Frequent reassurance about condition and progress Maintain a calm, quiet, restful environment

Drains see chart 27-6 Hemovac JP Penrose With the chest tube the oasis is the dry type the ocean is the wet type and it is important to monitor drainage for color amount airleak etc. Hemovac JP Penrose

Types of wound healing Phases of healing 1 inflammatory 2 proliferative 3 maturation Types of healing first: scar formation is minimal cover with dry sterile dressing second: granulation occurs in abscessed wound-scar forms third: used for deep wounds. Scar is deep and wide pack with gauze.

Post-Op Complications Evisceration Dehiscence SSI Atelectasis Pneumonia ileus Urinary retention DVT

Dehiscence Partial or complete separation of wound layers Wound is open Prevention? Tx is surgery or dressing

Evisceration Complete separation of wound layers Protrusion of internal organs Usually occurs 5-10 days post-op Prevention? Surgery. Know the postion to place them…and what to do with the dressing Both are emergencies. Call for help get pt to bed. Place supine with knees bent. Cover wound/organ with steril towels soaked in normal saline. Keep moist.. DO NOT push the organs in. VS q5 minutes. MOST important CALL the doctor.

Dehiscence Evisceration Complications on chart 27-4

Surgical Site Infections (SSI) Aseptic technique Most infections are caused by exogenous organisms Surgical wound classification (pg. 636) Risks: Obesity, smokers, malnourishment

Atelectasis and Pneumonia Collapse of alveoli Mucus accumulates Leads to fever and hypoxia Incidence of post op pneumonia 15% High fowlers IS, CDB Ambulate

Gastrointestinal N/V Flatus Bowel sounds Ileus-hypoactive bowel, delay in peristalsis

Urinary Retention Foley cath Must void within 6-8hrs Anesthesia causes relaxation, retention May have swelling from certain procedures
