You are an anaesthesiologist at the district hospital and have an appointment with patient Mr. Prochazka from the Department of Long-Term Care and Aftercare (80 years old, DM, COPD) for a preanaesthetic assessment before undergoing femoral amputation of the right lower limb for ischemia. He has already done an outpatient preoperative evaluation including the physical examination and some routine laboratory tests (coagulation tests, the complete blood count, fasting blood glucose, electrolytes and kidney function tests).
What further examinations are required?
The lung ventilation scintigraphy is used to study the regional distribution of lung ventilation for diagnosing COPD. So it is unnecessary exposure to radiation.
Chest X-ray is indicated for all patients 60 years and older, ECG for patients over 40 years of age. Spirometry test results are required due to COPD in anamnesis, urea and creatinine tests - these are referred to as renal function studies. Glycated haemoglobin and urinalysis tests are stated for prediction of diabetes compensation.
These aren’t any specific tests to determine the level of diabetes compensation.
