"What have we got?"

"19 year old male, two gunshot wounds to the chest and abdomen, and a laceration where a third bullet grazed him on his hip. He's hypotensive; BP is seventy over palp. One exit wound, the other bullet is in his abdomen."

"Ok, let's go! Clear trauma one!" Doctor Natasha Romanoff, chief resident of County Shield Hospital, New York, grabbed the gurney from the paramedics, and began wheeling it into the trauma room, followed closely by a few nurses and Steve Rodgers, the medical student.

"On my count, one, two, three!" The patient was lifted carefully onto the bed, and immediately a flurry of activity began.

"Steve, what do we do first?"

"Uh, CBC, ABG, CHEM7, and a coag panel," Steve said, as he swabbed the patients arm before sticking in an IV line.

"Right on. Pepper, get me two units of O-neg, and I think we're gonna need a chest film," Natasha called to a nurse in pink scrubs. "Shit, looks like we've got a collapsed lung. Call the OR, get Coulson down here stat!"

"Do we intubate?" Steve was pushing down on the entry wound on the patient's stomach.

"You up for the challenge?"

"Yep!" He waited for Pepper to take over putting pressure on the wound before moving up to the patient's head. He carefully opened the man's mouth and began sliding the tubes down his trachea, when there was a loud beeping from one of the monitors.

"He's in v-fib! Start CPR!" Natasha grabbed the paddles from the crash cart and held them out for Pepper to apply the gel.

"Charging to 200! Clear!"


Tony Stark walked into an exam room, closely followed by Clint Barton, nurse manager. On the bed was a boy, about five or six, with an extremely distressed mother holding tight onto his arms.

"Hey, kiddo, what's your name?" Tony squatted down to the boy's eye level.

"Finn," the kid whispered, holding tight to an action figure, possibly a superhero, Tony thought.

"Well, Finn, I'm Tony, and this man behind me in the pink scrubs is Clint."

"They're peach! For the last time!"

"So, what seems to be the problem?" Tony pulled a thermometer out from his coat pocket and gently slid it in Finn's mouth.

"He has a fever, and he was complaining about his ear hurting earlier," Finn's mother answered. "I think he might have a headache too, he keeps rubbing his forehead."

"Wow, 102 degrees. That's quite a fever. Do you want to open your mouth so I can look at the back of your throat?" Tony put the thermometer down on the instruments tray and clicked his penlight on.

"Could it be meningitis? Some kid at his school had it I think, could it have gotten to him?"

"I don't think it's meningitis, Mrs…?"

"Williams. And it's Ms, not Mrs."

"My apologies. Finn, how's your head?" Tony was standing now, and looking at the chart Clint had given him. "Finn?" The kid wasn't responding; it was like he hadn't heard Tony at all.

"Woah, Tony, you better get a look at this, there's a lot of discharge coming from his ear," Clint called, pulling the octoscope away, and grabbing a tissue.

"Ah. Ms Williams, your son has a perforated eardrum from an ear infection, that's what's causing the pus and the hearing loss. The headache is most likely caused by the fever dehydrating him. Normally we'd wait for the infection to pass, but because of the fluid coming from his ear, we're going to prescribe him a five day course of a liquid suspension antibiotic that he can take at home. Clint, would you help Finn and Ms Williams, and write them the prescription," Tony asked, before taking the chart out of the room to fill in the necessary paperwork at the reception desk.


"We've got a rhythm! There's a faint pulse too," Pepper called from her position at the man's arm.

"Excellent. Steve, can you suture the wound on his thigh, quick as you can before Coulson and the cavalry get here?" Natasha put the paddles down on the crash cart, before holding up the chest x-ray to the lights at the back of the room.

"Ok then, what have we got?" The doors to the trauma room burst open as Phil Coulson, head of surgery, walked in, closely followed by Melinda May, another surgeon and a couple of nurses.

"19 year old male, two gunshot wounds and a graze, which Steve is stitching up-"

"Hi," Steve waved cheerfully.

"The left lung was punctured by the bullet and subsequently collapsed, two broken ribs with some possible loose bone fragments, internal bleeding in the abdomen, as well as a stray bullet floating around in there somewhere," Natasha reeled off a list of the man's injuries, and by the end of it she was out of breath.

"Good work, Romanoff, we'll take him up now." Phil and May grabbed opposite ends of the gurney and wheeled him out of the room.

"Well done Steve, you have the makings of a real ER doctor," Natasha smiled, a rare thing, as she snapped her gloves off and untied her gown. Steve turned bright red at the compliment, and muttered his thanks.


A/N: This is a story co-written by me and my lovely friend Lizzie. We both have two obsessions: the MCU and the tv show ER (go watch it), so our natural instinct was to cross the two. None of the characters from ER will be in this, but we took the characters from the MCU and put them in the roles we thought they fitted in. There's gonna be a hell of a lot of medical jargon in this, it's wearing me out. Also, I may use British terms, but as I watch ER a lot, I don't think it'll happen too often.
