Why is the theory test done for urea and electrolyte and full blood count prior to surgery?
Preoperative testing can be done for a mixture of reasons. The bottom column is, we want to make sure the lenient is in the best possible condition beforehand he is subjected to the stress of surgery. Abnormalities in BUN, electrolytes or blood count/platelets may indicate further workup earlier surgery. Where I work, preoperative testing is guided by the individual patient’s age, condition, concurrent medical problems, and medication. If someone is on diuretics, we would want to check electrolytes to make sure he is not potassium depleted. If he is have major surgery, we requirement to know a blood count so that we know what the allowable blood loss is before we would consider transfusion. Some surgeons capture a load of test on every patient so the anesthesiologist doesn’t stop or delay the surgery base on lack of information.
