Indications
- routine preoperative laboratory testing not indicated for healthy patients undergoing low-risk surgery[7][8]
- standard preoperative tests in non-emergency operations (may be outdated or conditional on type of surgery)
- patients with < 1% risk for perioperative major cardiovascular event do not need additional testing[7]
Contraindications
- laboratory testing &/or imaging may be indicated in high-risk patients only[4]
- only indicated if results will affect management[7]
- only if an abnormal result is expected on the basis of known or suspected comorbidities & when the result would affect management[7]
- urine culture for bacteriuria not indicated[6]
- bleeding time not useful
Laboratory
- hemoglobin/hematocrit
- all women
- men > 60 years
- anticipated blood loss
- renal disease[7]
- further studies as indicated to identify cause of anemia[7][9]
- electrolytes, serum creatinine, basic metabolic panel
- patients > 60 years of age
- renal disease
- serum creatinine > 2.0 mg/dL a risk factor per Revised Cardiac Risk Index
- > 1.45 mg/dL associated with excess postoperative complications & death[11]
- low serum creatinine is associated with sarcopenia & frailty[11]
- associated with excess postoperative complications & death[11]
- serum creatinine > 2.0 mg/dL a risk factor per Revised Cardiac Risk Index
- diabetes mellitus, also obtain Hgb A1c
- medications that predispose to electrolyte imbalance
- steroids
- bowel preparations
- other risk of hyponatremia[5]
- PT/PTT & platelet count
- liver disease
- history of bleeding
- malignancy
- anticoagulation
- medical condtions that predispose to coagulopathy or bleeding
- not routinely indicated[7]
- liver function test
- cirrhosis
- history of abnormal liver function tests
- evidence of liver disease
- urinalysis
- suspected urinary tract infection
- planned urologic procedure
- planned implantation of prosthesis
- not necessary prior to joint arthroplasty[7]
- pregnancy test for all women in whom pregnancy is possible[7]
- consider arterial blood gas in patients at risk for postoperative respiratory failure
- preoperative serum NT-ProBNP predicts postoperative cardiovascular events[10]*
- stable patients whose laboratory tests were normal within 4 months do not need repeat laboratory testing prior to surgery[7]
* American College of Cardiology/American Heart Association guidelines recommend adding functional status (expressed in METs) plus a validated clinical risk score to guide risk stratification[13]
- serum NT-proBNP alternative to functional status[13]
Diagnostic procedures
- electrocardiogram within 1-3 months of surgery
- patients > 50 years of age
- functional status better predictor of cardiac complications than ECG in patients > 70 years of age[2]
- preoperative electrocardiogram indicated for asymptomatic patients with known cardiovascular disease & good performance status (> 4 METS)[7]
- not indicated in patients undergoing low-risk procedures[7]
- cardiovascular disease
- pulmonary disease
- diabetes mellitus
- patients > 50 years of age
- pulmonary function testing
- echocardiogram in patients with aortic stenosis (known or suspected)
- myocardial perfusion study would appear indicated if poor functional capacity (< 4 METS)
Radiology
- chest X-ray
- patients > 60 years of age
- pulmonary disease
- not routine in patients with chronic lung disease[7]
- acute pulmonary symptoms
- cardiovascular disease
