A
  • blow nose (to clear clots)
  • sit upright with head forward
  • cold compress over nose and on back of neck
  • after 5 minutes, may need septic or astringent
  • after bleeding has stopped, player may return to play –> don’t let them blow their nose for 2 hours (may remove clots and cause rebleeding)
74
Q

what is the mindset as a clinician caring for sport-related ocular injuries?
