The worst thing I saw in residency was a case of a 32 year old father of three who came presented with spontaneous pneumothorax. Chest tube was placed and he was admitted, usually no big deal. Next morning the incision was slightly inflamed and he had some pain and mild fever. Later in the day he had follow up with pulmonary and he had black spots on the skin, pus, tachycardia, confusion. He was immediately taken to surgery and necrotizing fasciitis had already spread to his upper arm and a large portion of his chest. Arm and pectoral gone and he was placed into a hyperbaric chamber. 8 hours later no improvement, wheeled back to surgery, chest wall resection, lat removed, infection nearing hip. Back into hyperbaric. 8 hours later no improvement, hip and both legs gone, lobectomy and large section of neck had to be resected. 8 hours later and he was dead. Guy went from healthy, athletic actually, to a head connected to half a torso then dead in a day.
