78 year old female w/femur fracture. diagnosed w/diabetes+emphysema. has other heart/lung condition. how to best treat fracture or reduce pain?

Go see your doctor: Need to discuss ortho options eg surgery vs no surgery. Depends upon where it occurred & how clean/bad is break. Also need to discuss best anesthesia options b/c could be difficult to wean off ventilator post-op. Lots of pain medications available. Traction can help temporarily reduce pain, too. Need to worry about delirium & dvt, too. Ask for consult w/geriatrician to help coordinate care.

Consider surgery: All the conditions you mentioned are chronic and manageable. A femur fracture is a very debilitating injury with a high mortality rate particularly in the elderly population. The surgical risk can be lowered by using regional anesthesia instead of general anesthesia.
