Ellen & her Dad discuss surgery for Alec

The story I'm frantically trying to finish on time, "The Man with the Knives" (about Alec on Kyros) needs, of course, a scene where he shows up and blows everyone in Sofia's village away with an unexpected feat of emergency surgery. My father's specialty is research & rheumatoid arthritis - but surely he knows enough to help me out? Particularly since he has a big collection of antique medical books. So: Phone call:

EK: . . . So anyway I've found a field manual from the Civil War online, but I'm not sure I understand what it's saying. [ADDED] Can I do something with crushed ribs and letting out a hematoma?
Dad: OK. Well, what century does this occur in?
EK: Sometime between 1500-1800
Dad: That's a little before the Civil War. [Discussion interrupted. Dad will call back later.]

EK emails Dad:

p. 107 "When the lungs are wounded . . . . "
??
earlier in chapter - trephining?

Dad to EK:
Yes!

Trephining is good.
From Wikopedia:
"Evidence also suggests that trephanation was primitive emergency surgery after head wounds[2] to remove shattered bits of bone from a fractured skull and clean out the blood that often pools under the skull after a blow to the head. "

Have him trephine to evacuate a subdural hematoma.
DAD

And so it goes. We just had a lovely talk about scalp wounds. Any surgeons out there?

Or even someone who can quote Patrick O'Brian chapter & verse? I betcha anything Stephen Maturin does cool surgery I could steal. Scalpels only, if possible, please. A drill would simply ruin the scene.
