The usual preoperative laboratory workup of any thoracic patient should include a coagulation profile consisting of a platelet count, international normalized ratio (INR), and activated partial thromboplastin time (aPTT). A complete blood count (CBC) and electrolyte count should also be performed, to screen for any hematologic derangements such as anemia or electrolyte abnormalities (eg, hypokalemia) that could impact anesthesia.
