Notes
- in general, proceed to urgent or emergency surgery without additional testing or medications
- in general, obtain a personal & family medical history before elective surgery
- frailty assessment in the elderly predicts postoperative complications[39]
preoperative medication management
- see perioperative management
- also see preoperative medication management guidelines from the Mayo Clinic[34]
preoperative laboratory testing
Cardiovascular risk for non cardiac surgery (also see cardiac stress testing)
- preoperative electrocardiogram
- not indicated for asymptomatic patients ungoing low-risk surgery[11]
- indicated for asymptomatic patients with known arrhythmia or cardiovascular disease & good performance status (> 4 METS)[11]
- within 3 months adequate[37]
- cardiac stress testing NOT needed for
- low-risk surgery[11]
- endoscopic surgery
- cataract removal
- superficial surgery under local anesthetic
- breast surgery
- ambulatory surgery
- except if
- unstable angina or myocardial infarction within 30 days

- severe valvular heart disease[11]
- age < 55 years, no cardiac murmur, no preexisting illness
- recent (6 month-1 year) normal coronary imaging & no new symptoms
- stable angina
- emergent surgical intervention indicated
- wait at least 9 months after ischemic stroke or TIA prior to elective non-cardiac surgery[18]
- low-risk surgery[11]
- preoperative cardiac stress testing reserved for patients with intermediate-risk or high-risk surgery when testing would influence management
- these are patients with low exercise tolerance & multiple major risk factors
- minimum functional capacity that obviates the need for preoperative cardiac stress testing is 4 METS (walking up a flight of stairs or a hill)
- CT angiography is an alternative to stress testing but may overestimate risk[45]
- adequate exercise tolerance is defined as >= 4 METS without symptoms[11]
- these are patients with low exercise tolerance & multiple major risk factors
- carotid ultrasound for asymptomatic carotid stenosis is not indicated
- asymptomatic carotid bruit is not predictive or perioperative stroke[11]
- carotid artery stenosis not associated with postoperative myocardial injury[20]
- combining carotid endarterectomy with cardiac surgery in patients with > 70% but asymptomatic carotid stenosis is associated with more perioperative strokes than cardiac surgery alone[21]
- major risk factors:
- congestive heart failure
- unstable angina
- myocardial infarction within 6 months
- critical aortic stenosis
- dysrhythmias, ventricular or supraventricular
- stroke within 2 weeks
- pulmonary hypertension[11]
- other risk factor requring preoperative testing
- signs/symptoms as risk factos:
- shortness of breath at rest or exertion
- chest pain or anginal equivalent
- prolonged palpitations, presyncope or syncope:
- pulmonary crackles
- increased jugular venous pressure
- gallop rhythm, irregular rhythm
- systolic murmur of aortic stenosis
- risk associated with surgical site (descending risk)
- vascular thoracic
- orthopedic
- abdominal
- otolaryngolic
- urologic, ophthalmic
- Laboratory:
- see preoperative laboratory testing
- preoperative serum NT pro-BNP predicts postoperative cardiovascular events[31][45]
- see preoperative laboratory testing
- Management:
- surgery without further testing for low-risk patients
- may include patients for orthopedic surgery
- if no risk factors[11]
- small area of reversible ischemia on nuclear stress testing[37]
- exertional angina after 30 minutes of walking briskly resolving with rest[37]
- may include patients for orthopedic surgery
- all usual cardiac & antihypertensive medications should be taken on the morning of surgery with a sip of water; continue statins in patients taking them[9]
- treat congestive heart failure until well compensated prior to surgery
- exception: proceed with emergency surgery without delay
- administration of loop diuretic while preparing for emergency surgery
- exception: proceed with emergency surgery without delay
- cardiac stress testing should be done only if the results of testing will affect management[11]
- estimated functional capacity as metabolic equivalents (METS) does not predict risk for MI or death at 30 days[29]
- non-invasive testing for intermediate risk patients
- echocardiogram for suspected aortic stenosis
- pharmacologic stress test prior to vascular surgery
- pharmacologic stress test prior to orthopedic surgery with risk of major adverse cardiac event > 1% (exercise stress test not an option)[11]
- exercise stress test before non-vascular surgery
- poor choice for a patient with knee osteoarthritis[11]
- preoperative electrocardiogram for asymptomatic patients with known cardiovascular disease & good performance status (> 4 METS)[11]
- MI within the last 6 months
- postpone surgery if possible
- cardiac catheterization with angioplasty may reduce cardiac risk to an acceptable level
- stroke: postpone elective surgery for at least 9 months after ischemic stroke[11][18]
- unstable angina
- postpone surgery if possible
- optimize medical management
- cardiac catheterization, PCI < 90 days prior to surgery may increase cardiac risk[11]
- moderate to severe aortic stenosis
- echocardiogram within 1 year or change in status[11]
- critical aortic stenosis
- consider valve replacement or valvuloplasty prior to elective procedure
- dysrhythmias
- consider cardioversion for atrial fibrillation
- target ventricular response for patients with chronic atrial fibrillation to undergo elective surgery is < 110/min[37]
- see direct oral anticoagulant vs warfarin or perioperative anticoagulation if patient anticoagulated
- sustained or complex dysrhythmias
- rule out electrolyte & blood gas abnormalities
- rule out MI, CHF exacerbation, PE
- rule out cardiac disease in patients with:
- perioperative beta-blocker reduces cardiac morbidity in patients with cardiovascular disease (see perioperative management)
- perioperative clonidine reduces mortality
- routine coronary angiography &/or coronary artery revascularization in patients with stable coronary artery disease NOT helpful before elective vascular surgery[5][6][9][11]
- delay elective surgery after PCI[9]
- 1-4 weeks for recipients of PCI without stents
- 4-6 weeks for recipients of PCI with bare metal stents
- >= 3-6 months recipients of PCI with drug-eluting stents[36]
- hold clopidogrel 5-7 days prior to surgery, continue low dose aspirin[36]
- hold prasugrel 7 days & ticagrelor 3-5 days prior to surgery
- witholding low-dose aspirin & clopidogrel may be reasonable if bleeding risk is extreme or consequences catastrophic, as with neurosurgery
- delay or cancel elective surgery for patients with pulmonary hypertension[11]
- refer patient for evaluation of pulmonary hypertension
- surgery without further testing for low-risk patients
Bleeding disorders

- inherited coagulation disorders
- acquired coagulation disorders
- quantitative platelet disorders - thrombocytopenia
- qualitative platelet disorders
- aspirin & other non-steroidal anti-inflammatory drugs
- clopidogrel (Plavix)
- renal insufficiency, uremia
- clinical manifestations:
- bleeding into soft tissues or retroperitoneum with hematoma suggests coagulation disorder
- mucosal bleeding, petechiae or purpura suggests platelet disorder
- arterial or venous thrombosis in a bleeding patient suggests DIC
- Laboratory:
- Management:
- obtain a personal & family medical history & bleeding history before elective surgery[37]
- desmopressin (DDAVP) 0.3 ug/kg over 15-30 minutes
- hemophilia A, hemophilia B, vWD, uremia
- effects lasts 6 hours
- cryoprecipitate 0.1-0.5 bags/kg preceding surgery, then 0.1-0.3 bags/kg every 12-24 hours
- factor VIII concentrate
- 30 units/kg followed by 10-20 units/kg every 12 hours

- follow platelet counts
Pulmonary disease
- complications:
- asthma
- bronchospasm
- inspissated secretions
- moderate asthma not risk factor for noncardiothoracic surgery[8]
- COPD
- obesity: NOT a risk factor for pulmonary complications[8]
- postoperative pneumonia
- asthma
- clinical manifestations:
- dyspnea, wheezing
- productive cough - best clinical predictor of post-operative complications
- barrel chest, hyperresonance, intercostal retractions, cyanosis, clubbing, active wheezing, rhonchi
- smoking
- Laboratory:
- pulmonary function tests
- indications
- lung resection
- controversial indications: age > 60. history of asthma or COPD, history of smoking, anesthesia requirement > 2 hours, upper abdominal or thoracic surgery
- not routinely indicated in patients with chronic lung disease[11] (see indications for preoperative laboratory testing)
- minimum pulmonary reserve necessary for general anesthesia
- no absolute value of FEV1 or FEV1/FVC precludes surgery[40]
- values do not help predict perioperative pulmonary complications
- indications
- arterial blood gas - as indicated
- pulmonary function tests
- Radiology
- chest X-ray
- as indicated
- not routine in patients with chronic lung disease[8][11]
- chest X-ray
- Management:
- smoking cessation 1-2 months prior to surgery reduces risk of postoperative complications[30]
- lung expansion maneuvers, incentive spirometry[30]
- preoperative inspiratory muscle training reduces risk of postoperative pneumonia & length of stay[30]
- training consists of 5-7 sessions/week for 2-3 weeks before surgery
- perioperative prophylactic respiratory physiotherapy reudces postoperative pulmonary complications (see perioperative management)[11]
- post-operative incentive spirometry of no benefit in preventing postoperative pulmonary complications[44]
- preoperative inspiratory muscle training reduces risk of postoperative pneumonia & length of stay[30]
- training in postoperative breathing exercises before upper abdominal surgery reduces postoperative pulmonary complications[28]
- COPD: aggressive postural drainage, chest physiotherapy & incentive spirometry
- continue beta-2 agonist bronchodilators pre- & post operatively
- stress doses of parenteral glucocorticoids for patients who had received parenteral steroids with the last year
- may not be required for patients receiving low-dose & short course glucocorticoids[11]
- reduce levels of theophylline in perioperative period
- toxicity of theophylline is enhanced by general anesthesia
- short course of broad-spectrum antibiotics in patients with productive cough to decrease volume of pulmonary secretions
- asthma:
- liberal pre-operative hydration for asthmatic patients
- patients taking inhaled steroids may need parenteral steroid coverage to avoid exacerbation of pulmonary disease in the perioperative period
- screening for obstructive sleep apnea (STOP-BANG)[11]
- use of nasogastric tubes is not recommended for prevention of postoperative pulmonary complications[44]
- delay or cancel elective surgery for patients with pulmonary hypertension[11]
- refer patient for evaluation of pulmonary hypertension
liver disease
- liver function testing if examination suggests liver disease
- delay elective surgery until evaluation of liver disease complete[11]
- in general, elective surgery is safe if MELD score < 8-10 & is not recommended if MELD score is > 14[11]
- a MELD score > 20 precludes elective surgery[42]
endocrine
- discontinue oral contraceptives 4 weeks prior to surgery[3]
- 2-4 fold increase risk of post-operative thrombosis
- delay surgery for severe hypothyroidism
- mild hypothyroidism is not a risk factor for postoperative complication[11]
- perioperative adrenal insufficiency
- patient-related risk factors
- primary adrenal insufficiency
- daily adrenal suppressive dose of glucocorticoid for >= 3 weeks in previous year (prednisone 10 mg QD)
- management
- if high risk surgery
- hydrocortisone 50-100 mg IV before surgery, then 25-50 mg IV every 8 hours for 24-48 hours
- if low risk surgery:
- usual dose of glucocorticoid on day of surgery
- if high risk surgery
- patient-related risk factors
- patients with untreated, asymptomatic mild hypothyroidism do not need preoperative testing or treatment[11]
renal disease
- electrolytes & serum creatinine
- BUN/creatinine ratio > 20 indicates azotemia, but does not increase risk for postoperative delirium[33]
- end-stage renal disease
- patients on renal replacement therapy should have dialysis the day prior to surgery[11]
Other considerations
=
- American Society of Anesthesiologists (ASA) score predicts postoperative complications
- frailty score better than ASA score in the elderly
- discontinue antiplatelet agents (aspirin & clopidogrel) unless low-risk surgery 7-10 days prior to elective surgery[7][11]
- discontinue Gingko biloba 6 days prior to elective surgery
- special considerations for warfarin (see warfarin & surgery)
- cervical spine radiography with flexion & extension views for patients with chronic or aggressive rheumatoid arthritis[11][13]
- delay of surgery for traumatic hip fracture is associated with increased mortality[11]
- screen for alcohol abuse (AUDIT-C)
- alchohol abuse before surgery increases risk of postoperative complications
- abstinence prior to surgery diminishes risk[12]
- depression (Geriatric Depression Scale score > 4) increase risk for postoperative delirium[33]
- screen for obstructive sleep apnea[11] STOP-BANG
- risk for arterial thrombosis or venous thrombosis is increased by sepsis (RR=3.3), septic shock (RR-5.7) & systemic inflammatory response syndrome (RR=2.5)[19]
- preoperative high-intensity interval training may improve cardiorespiratory fitness & reduce postoperative complications[38]
- pregnant patients should undergo same preoperative evaluation as non-pregnant patients[11]
- evaluate for Staphylococcus aurues nasal carriage & decolonize with mupirocin for 5 days with or without chlorhexidine body wash if positive[11]
