The primary outcome was the reduction of pain of 1 point at visual analogue scale for pain (VAS) after the 1 st hour of treatment (T1). Secondary endpoints included the reduction of pain of at least 2 points on the VAS scale at the 4 th hour (T4), the need of rescue therapy and the number of adverse events.
The purpose of this study is to monitor severe pain for femur fracture after treatment with paracetamol IV or OR.
