11. A 20 year-old motorcyclist has fractured his femur one hour previously on
the way home from the pub. He is in a cervical collar and his head is
immobilised. He states he has no pain in his neck on palpation. Cervical spine

D. Give ranitidine 50 mg IV and anaesthetise the patient in one hour with full
cervical spine immobilisation and a rapid sequence induction
E. Transfer to theatre immediately, remove the collar and with in-line spinal
stabilization perform a rapid sequence induction
Answer: E
