The purpose of a preoperative evaluation is not only to “clear” patients for elective
surgery, but rather
to evaluate and, if necessary, implement measures to prepare higher risk patients
for surgery. Pre-
operative outpatient medical evaluation can decrease the length of hospital stay as
well as minimize
postponed or cancelled surgeries.
To effectively provide this consultative service, we at Sattur Heart Care understand
the risk associated
with the particular type of surgery planned and relate this risk to the
patient's underlying acute and
chronic medical problems. The complete consultation includes detailed history ,
examination ,
investigations for evaluation and treatment, including prophylactic therapies to
minimize the
perioperative risk.
The below table shows some of the recommended tests which are followed:
CONDITION | INDICATED TESTING AND OTHER MEASURES* |
---|---|
Healthy patient ≤ 40 years | Hemoglobin, urine screening for pregnancy in women of childbearing potential |
Healthy patient > 40 years | Add ECG and blood glucose (age ≥ 45 years) |
Cardiovascular disease | ECG, chest radiographs, hemoglobin, electrolytes, BUN, creatinine, glucose (age ≥ 45 years or history of diabetes) |
Recent MI (≤6 weeks), unstable angina, decompensated CHF, significant arrhythmias, severe valvular disease | Cardiology consultation |
Previous MI (> 6 weeks ago), mild stable angina, compensated CHF, diabetes mellitus | Stress test if high-risk procedure or patient has low functional capacity; consider assessment of left ventricular function (i.e., echocardiography) |
Rhythm other than normal sinus rhythm, abnormal ECG, history of stroke, advanced age, low functional capacity | Stress test if high-risk procedure and patient has low functional capacity |
Pulmonary disease | Chest radiographs, hemoglobin, glucose (age ≥ 45 years), ECG (age > 40 years); provide patient with instructions for incentive spirometry or deep- breathing exercises |
Asthma | Pulmonary function testing or peak flow rate to assess disease status |
COPD | Consider pulmonary function testing and arterial blood gas analysis for assessment of disease severity |
CoughEvaluate for etiology | Evaluate for etiology |
Dyspnea | Evaluate for etiology |
Smoking | Counsel patient to stop smoking 4 to 8 weeks before surgery |
Obesity | Provide patient with instructions for incentive spirometry or deep-breathing exercisesAbdominal or thoracic surgery |
Abdominal or thoracic surgery | Provide patient with instructions for incentive spirometry or deep-breathing exercises |
Malnutrition | Laboratory tests based on primary disease, plus albumin and lymphocyte count; if malnutrition is severe, consider postponing surgery and providing preoperative supplementation |
