Textbook Question
Mr. Chu has been scheduled for surgery to have his arthritic hip replaced. His surgeon tells him he must switch from aspirin to acetaminophen for pain control before his surgery. Why?
Verified step by step guidance1
Understand the role of aspirin: Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that works by inhibiting enzymes involved in inflammation and pain. However, it also has an anticoagulant effect, meaning it reduces the blood's ability to clot by inhibiting platelet aggregation.
Recognize the risks of anticoagulants during surgery: During surgery, it is crucial to minimize bleeding. Since aspirin prolongs bleeding time by preventing platelets from forming clots effectively, it increases the risk of excessive bleeding during and after the procedure.
Understand the role of acetaminophen: Acetaminophen is an analgesic and antipyretic medication that relieves pain and reduces fever without affecting platelet function or blood clotting. This makes it a safer alternative for pain management in patients preparing for surgery.
Explain the surgeon's recommendation: The surgeon advises switching to acetaminophen to avoid the anticoagulant effects of aspirin, thereby reducing the risk of surgical complications related to excessive bleeding.
Conclude with the importance of following pre-surgical instructions: Emphasize that adhering to the surgeon's recommendations, such as switching medications, is critical for ensuring a safe and successful surgical outcome.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Antiplatelet Effects of Aspirin
Aspirin is an antiplatelet medication that inhibits the aggregation of platelets, which can increase the risk of bleeding. This is particularly concerning in surgical settings, where excessive bleeding can complicate procedures and recovery. Therefore, patients are often advised to discontinue aspirin prior to surgery to minimize this risk.

Acetaminophen as a Pain Reliever
Acetaminophen is a non-opioid analgesic that is commonly used for pain relief. Unlike aspirin, it does not have significant antiplatelet effects, making it a safer alternative for pain management in patients preparing for surgery. It helps control pain without increasing the risk of bleeding, which is crucial in the perioperative period.

Perioperative Care
Perioperative care refers to the management of patients before, during, and after surgery. It encompasses various considerations, including medication management, to ensure patient safety and optimal outcomes. Understanding the importance of medication adjustments, such as switching from aspirin to acetaminophen, is vital for minimizing complications during the surgical process.
