Perioperative Care Flashcards
Special considerations for gerontologic
- less physiological reserve (CO, sleep apnea, COPD, lung capacity)
- decrease subQ fat
- decreased mental status
- respiratory and cardiac leading cause of mortality
Special considerations for bariatric
- wound dehiscence, infection
- immobility
- increased cardiac demand
- increased O2 demand
- hypoventilation
- increased risk of pulmonary complication
Special considerations for disabled
- transfer and position
- mental status
- communication
Special consideration for ambulatory surgery
- someone has to drive them home
- > 24hrs
- condensed
Special considerations for emergency surgery
- not a lot of prep time
- not a lot of consent
Informed consent
- provider: obtains (out of scope for nurse to explain procedure/risk)
- pt: give (has to be autonomous, age, right to refuse, confident answ)
- nurse: witness (pt understand, clarify, call MD if pt change mind)
- any invasive procedure needs a consent form
Preoperative assessment
- baseline data
- meds/allergies (shellfish, px, OTC, supplements, herbal)
- nutritional,fluid status: always hydrate before surgery
- dentition: intubation/airway, increased infection with poor teeth
- resp and CV status
- hepatic, renal function: insufficiency increased mortality
- endocrine function
- immune function
- psychosocial: anxiety**
Diagnostics
- electrolyte**
- CBC**
- Cr and BUN
- blood type
- clotting
- urinalysis
- ABG
- pregnancy
Meds that can affect perioperative period
- corticosteroids (dexamethasone): help with stress, delay wound heal, mask infection, increase glucose, never DC abruptly**
- diuretics (HCTZ and furosemide): have enough electrolytes, holding before surgery
- tranquilizers (diazepam): decrease anxiety
- insulin: glycemic control = better healing
- antibiotics
- anticoagulant/salicylates/NSAIDS: stop 2wk before surgery
- anti seizure (carbamazepine)
- thyroid (levothyroxine): hypothyroidism, give before surgery
- opioids
- OTC/alcohol
Preoperative nursing interventions
- pt edu: deep breathe, cough, mobility, pain mgt
- consent
- NPO
- skin prep
- warm blanket: thermo reg
- VS
- minimize anxiety
- DVT prevention
Preoperative complications
- opioids: respiratory distress, decrease CNS, safety risk
- sedatives (BENZOs): safety, decreased CNS
- IV infusions: avoid fluid overload (crackles, edema)
- GI meds: antiemetic**, antacids, H2 receptor blockers
Circulation nurse responsibilities
- responsible for team
- setting up OR
- counting
- specimen collection
- documents
- privacy
General anesthesia
- general anesthesia: less of protective reflexes, not arousable
- assessment: type of procedure, age*, length of time, comorbidites
- inhalation agents: halothane, isoflurane, nitrous oxide (add O2)
- IV anesthetic agents: propofol (egg/soybean allergy, short half life)
Regional anesthesia
- injected in certain area around the nerve
- effect depends on type of nerve
- spinal: provides autonomic, sensory, motor, no movement
- complications: headache (size of needle, fluid leak, dehydrated)
- epidural: blocks pathways but motor function intact (check for epinephrine)
Anticholenergics
- atropine (increases heart rate)
- bradycardia, heart block
Neuromuscular blocking agent
- AIRWAY!! They will not be able to breathe!!
- succinylcholine/vecuronium
- block impulse to nerve muscles relaxes
Intraoperative complications
- anesthesia awareness: they stay asleep
- N&V: risk for aspiration (roll onto side or turn head)
- respiratory: intubation, ventilation, hypoventilation, air occlusion)
- malignant hyperthermia
Malignant hyperthermia
- can happen immediately
- dantrolene
- trigger: inhalation anesthetic agents and succinylcholine**
- early signs: tachycardia, increased CO2, decreased O2, musicale rigidity
- treat by lowering room temp, ice, ventilation, cold gas
Intraoperative nursing interventions
- reduce anxiety
- safety
- monitoring, managing potential complications*
- pt advocate
Initial PACU assessment
- priority ABCs FIRST**
- keep them awake and breathing
- are they breathing and is it effective
- supplemental O2: meets O2 demand from blood loss or increase metabolism
- O2 sat EARLY WARNING**
- assess tissue perfusion, peripheral pulses, cap refill
Maintaining patent airway
- provide supplement O2
- assess breathing
- positioning: HOB elevated 15-30 unless
- TCDB
- unable to cough?- may require suctioning
- vomiting: reposition left lateral
When do you remove an oral airway
Until evidence of gag reflex returns
Maintaining cardiovascular stability
- potential for hypotension, shock: common cause I replaced fluid/blood loss
- potential for hemorrhage
- potential for HTN (brain, heart, kidneys): from sympathetic stimulation from pain, anxiety, bladder distention, respiratory comp
-leading cause of dysrhythmias: hypokalemia**, hypoxemia, alteration in pH, circulatory instability, preexisting heat disease, hypothermia, pain surgical stress, medications
Indicators of hypovolemic shock/hemorrhage
- changes in LOC
- pallor
- cool, moist skin
- tachypnea
- cyanosis
- rapid, weak, threads pulse
- hypotension
- narrowed pulse pressure
- concentrated urine
Relieving pain and anxiety
- assess reassess
- control environment: low lights, noise level**
- nonpharmacologic approaches to pain
- anxiety: BENZOs**
- splinting
- positioning
Response to anesthesia
- sedation: hepatic and renal insufficiency can cause oversedation, safety
- N/V: needs to be treated immediately
Genitourinary- I&O
- monitor I&O Intraoperative and PACU (urine 30/mL)
- postop lab
- skin turgor
- admin IV fluids as indicated
- blood products
- bladder distention
- adequate UO
Managing potential complication nursing interventions
- airway obstruction: resp assessment—low O2 sat, irregular resp, cyanosis; pull tongue forward and open airway; resuscitation equipment
- hypoxia: elevate HOB, TCBD, frequent repositioning, monitor O2 sat
- hypovolemic shock: decreased BP?UO, increase HR/RR, narrowing pulse pressure, slow cap refill; O2, supine with legs up, IV fluids, vasopressors
- paralytic ileus: bowel sounds, ambulating, advance diet, metoclopramide (increase GI emptying), NG tube
- wound dehiscence: cover with moist sterile saline, reassure pt, get help, low Fowler with knees flexed, monitor for shock, call HCP
