B. Emergent hand surgery consultation- the high pressures associated with industrial equipment generate force to penetrate skin and fascial planes- paint and paint thinner produce a large, early inflammatory response and lead to the largest % of amputations- other materials that can be injected are grease, oil, hydraulic fluid, plastic wax, H2O, and semifluid cement- grease causes a smaller inflammatory response but causes formation of granulomas, fistulas, scarring, and loss of function- patients who present early might have minimal physical findings- Tx - aggressive pain management with IV opiods, IV abx, tetanus- early surgical debridement is required to prevent amputation and disability

Gross dirt and organic debris are on both the proximal amputation site and the amputated part. The patient is R handed with no PMHx. What is the next step to improve the chance for successful replantation?A. Gently wash both the amputated digit and the proximal site with hydrogen peroxide, then replace digit in the iceB.

C. Remove amputated part from cooler, wrap it in NS soaked gauze, then refrigerate it in a plastic bag- more proximal the amputation, the less ischemia time the digit can tolerate- Xrays of amputated tissue and stump- prophylactic abx- cooling amputated part to 4 C lengthens ischemic time from 6-8 hrs to 12-24hrs- local antiseptics should not be used because they can be toxic to viable tissues- ice should not come into direct contact with tissue because this can cause local tissue damage

difficult to assess due to the difficulty of isolating muscles in each compartment

- Tight swollen hand in “minus” position

- Pressure >15-20 is relative indication for fasciotomy
