Pharmacological Principles and Drug Interactions in the ICU
摘要
An 84-year-old male was admitted to the intensive care unit with a history of syncopal attack at home, after a day-long fast for religious reasons. In the emergency department, his heart rate was 35/min, and BP was 80/60 mmHg. His lab results were normal except for a serum creatinine level of 3.2 mg/dl (baseline: 1.4 mg/dl, 3 months ago) and a potassium level of 6.2 meq/L. ECG showed a complete heart block. On medical reconciliation, he was found to be taking atenolol 50 mg once daily and telmisartan 40 mg once daily for his hypertension. His son also showed a tablet of aceclofenac (100 mg) that he had purchased over the counter from a chemist shop for his back pain.
