Ketamine for RSI in Hemodynamically Unstable ED Patients
Recall that ketamine acts as a sympathomimetic resulting in increases in heart rate, blood pressure, and ultimately cardiac output.
Because of its rapid transport across the blood-brain barrier, its sympathomimetic effects, and lack of significant adverse effects, ketamine is recommended by many organizations as a first line agent for RSI in unstable patients.
Important contraindications to ketamine include an acute coronary syndrome, aortic dissection, and acute heart failure.
Take Home Point: Consider using ketamine the next time you need to intubate a hypotensive, critically ill ED patient.
