[Answered]: Scenario: You are the surgical technologist…

Scenario: You are the surgical technologist circulating during an on-pump coronary artery bypass grafting (CABG × 4) procedure. Thirty minutes after the patient is successfully weaned from cardiopulmonary bypass and protamine has been administered, the perfusionist suddenly notifies the team that the arterial line pressure has spiked to 450 mmHg and the line is shaking violently. The surgeon looks up and says, “We’ve got air in the arterial line!” The anesthesiologist simultaneously notes that the patient’s end-tidal CO2 has dropped to zero and the blood pressure is falling rapidly. Questions: 1. As the surgical technologist, what is your immediate first action when the team announces massive air embolism in the arterial line? 2. While the surgeon and perfusionist are managing the air lock, what specific emergency equipment or supplies should you have immediately available at the table or in the room, and why? 3. Once the patient is placed back on full cardiopulmonary bypass to manage the air embolism, what positioning change does the surgeon typically request, and what is the rationale behind this position? 4. From a surgical technology standpoint, how could this catastrophic event have been prevented during the de-airing process prior to coming off bypass? Name at least three specific techniques or checks the team (including the ST) should have performed. 5. Massive air embolism is a “never event” in cardiac surgery. If this occurred in your OR, what immediate documentation and reporting responsibilities would you have as the surgical technologist (both intraoperatively and postoperatively)?
