Updated: 4 days ago
Season 9 of ER is defined by a shift from the personal tragedy of Season 8 to large-scale, high-stakes medical crises. The season opens with a chaotic hospital evacuation due to a Monkeypox outbreak and transitions into complex ethical dilemmas in the Congo. Domestically, the team manages catastrophic trauma cases, including the amputation of Dr. Romano's arm and mass casualty events like a cyanide suicide pact. The medicine is gritty and resource-intensive, often highlighting the disparity between first-world care and field medicine in conflict zones.
Below is a comprehensive, episode-by-episode review of the medical cases, diagnoses, and treatments presented in Season 9.
