2025 Multiprofessional Critical Care Review: Adult Online-Cardiovascular Surgery Complications

Video Transcription

Video Summary

The discussion covers critical post-cardiac surgery complications and management strategies. A 65-year-old post-CABG and aortic valve replacement patient developed hypotension due to a pericardial hematoma causing right atrial compression (focal tamponade), necessitating urgent surgical washout rather than pericardiocentesis. Emphasis was placed on using transesophageal echocardiography (TEE) for diagnosis when transthoracic echo is limited. Vasoplegia, common post-bypass, involves hypotension with preserved cardiac output; vasopressin is preferred over norepinephrine, and rescue therapies include methylene blue and hydroxocobalamin. Cardiac arrest management post-surgery deviates from usual protocols, prioritizing defibrillation over immediate chest compressions. Pacemaker troubleshooting highlighted capture and sensing failures, with optimal pacing modes like AAI preferred to maintain AV synchrony and improve cardiac output in bradycardic patients. For acute decompensated heart failure with extensive coronary disease and mitral regurgitation, intra-aortic balloon pump (IABP) was favored over impella, especially with LV thrombus, to stabilize the patient pre-surgery, as IABP improves coronary perfusion and lowers afterload.
