Episode 1

Triple Organ Transplant Following Catastrophic Brain Injury

Sarah Martinez & Liam Collins. The season opener centers on the aftermath of a tornado that blew a bus off a cliff, resulting in a mass casualty event. This tragedy led to a surge in organ availability, specifically involving a donor patient, Liam Collins. Liam was declared brain-dead following rigorous testing, including clinical exams and brain scans. The Recipient: Sarah Martinez was in critical condition with deteriorating cardiac and liver functions. Treatment: A rare triple organ transplant (heart, liver, and likely kidneys) was performed by Dr. Grey and Dr. Marsh. Despite complications involving the consent process due to an intern's error regarding the donor's identity, the long surgery was successful. Sarah was weaned off ECMO and woke up post-operatively.

Other Medical Conditions Discussed

1. Brain Swelling: Managed with ventilators to reduce cranial pressure in trauma patients.

2. Hematomas on the Heart: A condition rendering a potential donor organ unusable due to clots.

3. Panic Attack: Experienced by a new resident returning to the hospital where her mother died.

4. Immunosuppression: Discussed in the context of post-transplant care to prevent rejection.

Episode 2

Meningococcus Leading to Septic Shock and Amputation

Chase. A 19-year-old college student presented with symptoms resembling food poisoning (vomiting, chills) after eating leftover rice. However, the illness rapidly progressed to septic shock, characterized by a purple, star-shaped non-blanching rash (petechiae) and signs of Disseminated Intravascular Coagulation (DIC). Diagnosis: Dr. Griffith diagnosed meningococcal disease, noting the patient was unvaccinated and living in a dorm. Treatment: Due to severe vascular compromise and gangrene caused by the septic shock, the patient required a below-knee amputation. The surgery was complicated by uncontrollable coagulopathy but ultimately saved his life.

Other Medical Conditions Discussed

1. Skin Necrosis: Tissue death caused by sutures tied too tightly.

2. End-Stage Renal Disease (ESRD): Discussed along with its top causes: hypertension, diabetes, and glomerulonephritis.

3. Steven Johnson Syndrome (SJS): Considered as a differential diagnosis for the rash.

4. Bacillus cereus: The initial suspected cause (food poisoning) before the severity of the rash was noted.

Episode 3

Ovarian Torsion Secondary to Ovarian Cyst

Diamond. A teenager collapsed during a sex-ed class with tachycardia and warmth. While initially dismissed as painful periods, imaging revealed a giant cyst on the left side and a "whirlpool sign" on the right, indicative of ovarian torsion. Treatment: Dr. Montgomery and Dr. Wilson performed immediate surgery to untwist the ovary and drain the cyst, successfully salvaging the organs and preserving fertility.

Other Medical Conditions Discussed

1. Hysteria: Referenced as a defunct historical diagnosis for women's symptoms.

2. Sepsis (Post-Abortion): Discussed as a risk of unsafe abortions in a restrictive legal landscape.

Jarah Al-Hasan. A 16-year-old under the influence of LSD jumped off a roof and missed the pool. He presented with hypotension and a flail chest (multiple broken, displaced ribs). Progression: His condition deteriorated due to massive blood loss from a chest tube. Emergency surgery revealed a lacerated pulmonary artery. Dr. Pierce manually compressed the vessel to control the bleeding before repairing it.

Other Medical Conditions Discussed

1. LSD Intoxication: The precipitating factor for the trauma.

2. Hemothorax: Blood in the chest cavity requiring drainage.

Progression: During transport, the pregnancy ruptured, causing hemorrhagic shock. Dr. Montgomery attempted to insert a Foley catheter balloon to tamponade the bleeding, but the patient coded and died from exsanguination.

Glioblastoma Recurrence

Catherine Fox. Scans revealed Catherine’s tumor had grown by two millimeters. She refused conventional treatment (IDH inhibitors, immunotherapy) due to past side effects, opting for alternative energy medicine while keeping the recurrence secret.
