Also known as: Third-degree burn
Dana suffers second and third-degree burns to her head and left forearm (20% total body surface area) from a fire. Shaun initially misdiagnoses the severity, performing inadequate debridement that leads to graft failure. A second surgery with deeper debridement and temporoparietal fascia flap is required, which Shaun successfully completes.
Also known as: Broken back
Grant, a firefighter injured when pinned by a beam, has an unstable lumbar fracture requiring fusion surgery. Dr. Park attempts a high-risk short-segment posterior fusion to preserve Grant's career but encounters uncontrollable bleeding and must switch to a longer fusion that ends Grant's firefighting career.
Also known as: Perforated intestine
Grant's abdominal trauma from the beam includes a duodenal rupture with internal bleeding, which Dr. Park successfully repairs during emergency surgery before addressing the spinal fracture.
Also known as: Cold exposure
During Dana's initial burn surgery, she develops hypothermia leading to v-tach. Shaun identifies this and implements aggressive fluid resuscitation with a rewarming catheter, stabilizing her cardiac rhythm.
