Cardio Resp Problems and surgery Flashcards
Reduced ventilation outcome measure
Asucultation
Reduced air entry outcome measure
palpation, x-ray, spirometry, ABGs
Dyspnea outcome measure
Inspection, Dyspnea measure, patient report
Impaired secretion clearance outcome measure
Auscultation, sputum and cough asessment, tactile fremitus, chest X ray, subjective report
Decreased endurance outcome measure
Subjetive patient report of fatigue
Exercise test - 6MWT
Borg RPE scale
Airflow limitation outcome measure
Spirometry - reduced FEV1/FVC ration
Inspection (barrel chest, prolonged expiration, pursed lip breathing)
WHeeze on auscultation
X ray (horzontal rubs, flattened diaphragm,)
Narrow mediastinum
Reduced chest expansion outcome measure
Chest expansion
Lobectomy
resection of one or more lobes of the lung
a. For carcinoma
b. Bronchus leading to lobe are cut and stapled
Remaining lung expands to fill space
Pneumectomy
total removal of one lung
a. For extensive carcinoma
b. Mainstem bronchus stapled off
c. Diaphragm rises and mediastinal structures shift to empty side
Segmental resection
a. Removal of a segment of a lobe
Done for localized lesion (cyst, benign tumor)
Wedge resection
Removal of small area of lung
For large bullae cyst, biopsies, fungal disease
Lung biopsy
surgical removal of lung tissue for diagnosis
Lung volume reduction
removal of badly affected portion of emphysematous lung to reduce hyperinflation and improve lung mechanics
Coronary artery bypass surgery
saphenous vein or internal mammary artery is used to bypass narrowed coronary artery and restore blood flow to heart
Valve repair/replacement
mechanical or biological valve repairs or replaces dysfunctional valve
Pacemaker/Implantable cardioverter defibrilator insertion
a. PM: electrical impulse sent to contract heart
ICD: sends shock to reset an abnormal heart to normal
Anterolateral thoracotomy
sub mammary incision from midline to 4th or 5th intercostal space at midaxillary line
- Muscles cut: pec major, serratus, intercostal
-problems :Limits shoulder movement
Posterolateral thoracotomy
from area between scap and vertebrae to anterior axillary line at 5th intercostal space
Muscle cut: trap, lat, serratus, rhomboid
Problems: Scapular instability, scoliosis to operated side
Thoracoabdomina
8th or 9th intercostal space at posterior axillary line to midline of abdomen
Muscle cut: lat, serratus, ext oblique, rectus abd
Problems: Difficulty coughing, deep breathing and thoracic expansion + Leads to forward flexion posture (splinting)
Median sternotomy
vertical incision of sternum
- Used to access mediastinum
- No muscle cut
Problems: Kyphosis and splinting due to pain, reduced chest expansion
Effects of anaesthesia on respiratory system
- Decreased FRC –> atelectasis and shunting
- Decreased respiratory drive (decreased central chemoreceptor sensitivity –> decreased ventilation)
- Respiratory muscle weakness
- Decreased cough (increased risk of aspiration)
- Decreased lung compliance
- Hypoxemia
Effects of anaesthesia on cardiovascular system
- Hypo or hypertension
- Hypovolemia
- Dysrhythmias
Risk of myocardial ischemia and infarct
Deep Venous Thrombosis (Signs, prevention treatment)
Thromboembolism - when blood clot breaks off and travels to obstruct a blood vessel
- Pulmonary Thromboembolism is blocking lungs
Signs and symptoms: Unilateral leg pain or swelling, Localized warmth, Erythema (red)
, Pain on passive DF (positive homans test)
Prevent via: Early mobilization, Lower extremity exercises, Bed exercises, Graduated compression stockings
Treatment: Blood thinning
Monitor
Atelectasis definition and causes
partial or complete collapse of lung or lung section *Occurs within 24-48hrs after surgery)
Causes: hypoventilation, Decreased FRC, Airway restriction by retained secretions from
1) Reduced ciliary function
2) Reduced cough reflex
3) Pain
Can lead to V/Q mismatch –> hypoxemia
Risk for post operative complications patient related
- Pre existing pulmonary or cardiac or neuromuscular disease
- Over 60
- Decreased PA
- Active smoker
- Skeletal deformities (kyphosis)
Malnutrition
Surgery related post of risks
- Type/location
○ Aortic>thoracic>upper abdominal > lower abdominal > non abdominal or thoracic- Duration of anaesthesia (>3 hrs increases risk)
General anaesthesia has more risk than epidural
- Duration of anaesthesia (>3 hrs increases risk)
Perioperative goals
- Decrease post op complications
- Decrease hospital stay length
- Increase self efficacy
Decrease anxiety
Pre operative goals
- Develop rapport
- Assess patient (cough, cognitive status, risk)
- Create post op goals
- Educate
- Describe and demo post op interventions
a. Breaths
b. secretion clearance (coughing and hughing)
c. Circulatory exercises (ankle pumps)
d. Positions and transfers
Early mobilization
Post operative goals
- Optimize pain management
- Promote lung expansion and prevent atelectasis
- Facilitate secretion clearance
- Prevent circulatory complications (reduced DVT)
- Restore exercise tolerance
- Maximize chest mobility
- Maintain and restore ROM and strength
Preserve skin integrity
