Also known as: GSW to chest
Stefan suffers a gunshot wound to the left lower chest that initially appears to injure his lung, causing a hemothorax. The case later reveals the bullet struck the apex of his heart, leading to life-threatening cardiac tamponade requiring emergency pericardiocentesis and surgery.
Also known as: Blood in chest cavity
CT reveals a small hemothorax from Stefan's gunshot wound, with minimal but steady chest tube output. Initially thought to be the primary injury, but later revealed to be secondary to cardiac injury.
Also known as: Blood around the heart
Stefan develops cardiac tamponade when the gunshot wound to the apex of his heart causes blood to accumulate in the pericardial sac. He goes into PEA arrest requiring emergency blind pericardiocentesis in the PICU before transport to the OR.
Also known as: GSW
Hector, a rival gang member, arrives with a gunshot wound to the shoulder in what appears to be a retaliation shooting. His presence in the hospital creates the central conflict driving the episode's security concerns.
Also known as: Brain cancer
Ivy is a 16-year-old with stage 2 (incurable) glioma that recurred three months ago. She refuses treatment, but imaging reveals the tumor is actually shrinking. The episode reveals her boyfriend has been secretly administering chemotherapy (Temodar) in her tea without her knowledge.
Also known as: Seizure
Ivy presents with a seizure, which is later understood to be a complication of both her brain tumor and the secret chemotherapy she has been receiving.
Also known as: Esophageal tear
Ivy develops a Mallory-Weiss tear in her esophagus from repeated vomiting (a side effect of the secret chemotherapy). This causes significant bleeding requiring emergency endoscopy to cauterize the vessels.
Claire presents with severe hemorrhaging from her transplanted uterus. Ultrasound reveals severe thickening of the endometrial stripe causing uncontrollable bleeding. When medical management fails, she requires emergency hysterectomy and receives a live donor uterus from her sister.
Also known as: Uterine scarring
Claire's medical history includes Asherman syndrome (acquired uterine scarring) which necessitated her original uterus transplant. This is mentioned as background for her current transplant complications.
Also known as: Blood clotting disorder
Claire develops coagulopathy from her prolonged uterine bleeding, making her a poor surgical candidate. During transplant surgery, this leads to significant bleeding and cardiac arrest requiring resuscitation.
Also known as: Chemo side effects
Ivy unknowingly receives oral chemotherapy (Temodar) concealed in herbal tea by her boyfriend. The medication causes severe nausea and vomiting leading to the esophageal tear, while also shrinking her brain tumor. This secret poisoning constitutes assault and creates the episode's main ethical dilemma.
