Why do SCDs need to be on the patient prior to anesthesia induction?

  1. Hi everyone!
    During my nursing internship I was taught that SCDs should be on prior to anesthesia putting the patient to sleep. I cannot remember the rational behind this, but it had something to do with excitability and maybe higher chance of a DVT during that time? I tried to find evidence based articles around this topic, but haven't had much luck. Instead I have found research that suggests the opposite, SCD placement can happen at any time during surgery...

    It seems that if you put them on before induction, the patient will be able to cooperate with placement and tell you if they're rubbing anywhere, causing pain or otherwise uncomfortable. But I'm just an ICU nurse, so perhaps someone from the peri-operative team will chime in.

    General anesthesia has been shown to decrease lower-limb venous return profoundly, and Kiudelis et al16 stated that 50% of anesthetized patients develop some degree of venous stasis intraoperatively because of anesthetic vasodilatation effects similar to those produced by 10 to 14 days of bed rest, which affect the clotting cascade.
    Placing the SCDs and starting them after the patient is anesthetized may mean having to play catch up instead of being a true prophylactic measure.
