"I’m trying to save a baby here, get out of my face." (6x08, Invest in Love)

One part of the storyline in Episode 8 of Season 6 centers around a baby born two months premature.  Karev is assigned to the case and because of the awful point his life is in at the moment his mind is almost set on the fact that this child is going to die.  He holds her one last time whispering to her that she is not alone.  When Bailey comes and finds him holding the baby she recalls something that we learned about when going over the senses and nerves.  The touch system is crucial to a developing child.  When in the womb, babies are able to hear their mother's heart beat and voice.  And when babies are born premature they are left to develop in an intensive care unit in a hospital wing.  Karev removes his shirt so he can hold the baby close to him and she can feel the skin on skin contact and the heat of his body.  This helps babies develop better and, in this episode, is also what gets the baby's heart kick-started and allows her to survive.

"Are you really so messed up that you can't let one person be nice to you, ever?"
"I can't go.  I can't go home, I can't get Izzie to call me back.  She's gone - could be dead for all I know!  She left me with a $200,000 medical bill, and I- I can't do anything about it, about any of it.  But I can sit here and I can hold this baby.  That I can do."

"We have to learn our own lessons." (1x06, If Tomorrow Never Comes)

There are four major problem solving approaches: Algorithmic, Heuristic, Insight, and Intuition.  The algorithmic approach involves methodical, logical step taking and is the longest process but results in the least amount of mistakes.  Heuristic problem solvers tend to make quick judgements and go off of past experiences.  They are not the best exam takers and tend to make mistakes much more often.  Insight is usually guided by a sudden novel solution that just comes to you.  This also includes learning from the mistakes of both oneself and others.  Intuitive problem solvers figure everything out with sudden feelings or thoughts.  They don't need practice, they just know exactly what to do.

Christina Yang is a cardiothoracic surgical fellow at Seattle Grace hospital.  Yang graduate from Berkeley and Stanford University and, just like all the others at Seattle Grace, has worked exceptionally hard to get to where she is. Yang is an algorithmic problem solver.  She thinks things through before acting, practices before big surgeries and other activities, and plans out steps to get to where she needs to be.  She knows that no matter how long it takes to finish her job, it will be worth it because she knows that she will be doing her absolute best.

Alex Karev is a resident pediatric surgeon who commonly uses heuristic approaches.  He is known for his egocentric attitude and tends to let his bad attitude get the best of him.  He makes many judgements and knee-jerk reactions without thinking things through all the way.

Mark Sloan was an insightful surgeon and had been referred to as the "go-to-guy" for plastic surgery by Karev (while he was being mentored in plastics by Sloan).  He never really thought things through all the way, and the best ideas would just come to him.  Although he wasn't always successful in his attempts and actions, he still had a consistantly high number number of good outcomes.

Miranda Bailey is an attending specialized in general surgery.  She was referred to as The Nazi because of her intimidating personality, but was always the person who everyone went to for answers.  Bailey always knew just what to do in any given situation, even in the case of the two teenagers who super glued themselves together so they'd never have to part.

(If you're wondering, warm soapy water mixed with acetone - that super glue won't stand a chance.)
