Protecting the numb arm or leg

  • Make sure the cast or splint is not too tight. You should be able to slide one finger under it.
  • Make sure the sling or brace is on correctly.
  • Do not lean on, or put any type of unnecessary pressure on the arm or leg.
  • Do not let your child sleep in a position that puts pressure on the arm or leg.

Pain medicine

  • Give pain medicine at the first sign of discomfort.
  • As the nerve block wears off, pain may increase.
  • If at 6 hours (________________ am / pm) you have not taken any pain medicine, take the low dose prescribed by your doctor.
  • If your child has gone to bed within 8 hours of the nerve block placement, be sure to wake up your child 8 hours (________________ am / pm) after the nerve block was placed and give pain medicine if needed.

When should I call for help?
