Also known as: Brain bleeding
Jerry Hoffman sustained a traumatic subarachnoid hemorrhage from the sinkhole collapse, requiring neuro monitoring but not surgical intervention.
Also known as: Broken arm
Jerry Hoffman's arm was fractured in the sinkhole collapse and was splinted by Jackson.
Also known as: Trampled
Nicky sustained severe crush injuries from the sinkhole collapse requiring bilateral fasciotomies to relieve compartment syndrome. He also developed renal artery thrombosis requiring an interposition graft.
Also known as: Broken spine
Nicky had three spinal fractures requiring surgical stabilization by Derek Shepherd. There was significant epidural bleeding that needed to be controlled during the procedure.
Also known as: Blood clot in kidney artery
Alex discovered renal artery thrombosis threatening Nicky's kidney and performed an interposition graft to save it.
Also known as: Leg amputation
Susannah's leg was trapped under her car in the sinkhole and required field amputation by her husband. This is a central dramatic moment driving the episode's plot.
Also known as: Broken pelvis
Susannah sustained a severe pelvic fracture in the sinkhole collapse that contributed to her hemorrhagic shock and was part of the complex gunther case.
Also known as: Heart sac tear
Cristina correctly diagnosed a pericardial tear causing cardiac tamponade, requiring thoracotomy during the gunther procedure. The patient went into v-fib and required multiple interventions.
Also known as: Shock from blood loss
Susannah was in hemorrhagic shock from multiple sources of bleeding including her pelvis, abdomen, and heart injuries. This was the central challenge of the gunther case.
Also known as: Ruptured spleen
A patient was scheduled for splenectomy but nearly went to the OR as the wrong patient due to the chaotic board management on Kepner's first day as chief resident.
Also known as: Collapsed lung
A patient from the sinkhole developed tension pneumothorax that Meredith treated with needle decompression despite being fired, leading to conflict with Bailey.
Also known as: Fractured windpipe
A sinkhole victim arrived with tracheal injury that prevented normal intubation, requiring alternative airway management.
Also known as: Brain bleed
Danny sustained a rim subdural hematoma from the sinkhole collapse that Derek assessed would likely reabsorb without surgical intervention.
Also known as: Abnormal EKG
Alex's underlying arrhythmia was revealed when Cristina accidentally gave him intracardiac epinephrine, causing him to code. This creates tension between the residents.
Also known as: Diabetes
Henry undergoes experimental islet cell device insertion for his diabetes, with Teddy worried about why Webber rushed the surgery. This subplot explores Teddy's anxiety about Henry's condition.
