Deja vu all over again. This thread comes around a lot.
I've been on two backcountry trips in which someone got a severe laceration. Both times, there were two surgeons present on the trip (and enough medical supplies to stock a MASH unit!). NEITHER time did the surgeon(s) want to suture. Asked recently, both agree that they'd never suture in the field. NEVER. They may use a suture to ligate a bleeder, but would never, never, never suture a wound closed.

So... I suggest a poll of forumite who are actually MDs, or EMS/EMTs.

1) Would you use a suture to ligate or tie-off a bleeder... in the field.. if you had no hemostat?

2) Would you suture a wound closed in the field. (Assuming all the "sterility" you can muster in the field)
