Detailed Description:

Limb trauma is a painful condition that requires urgent analgesic treatment . Intravenous Opioids and NSAIDs are used extensively to control pain; both of them are with side effects. Paracetamol is a safe and effective analgesic that is used by oral or rectal routs for pain control, and in therapeutic doses has less side effects than Morphine and NSAIDs, and approved as a safe and effective analgesic in emergency department.

recently Iv Paracetamol has become available in European countries and also in Iran.

efficacy and safety of IV Paracetamol has been studied in post operation conditions and asserted but in emergency setting it has been studied only in renal colic situation.

Therefore, the investigators want to study the efficacy of IV Paracetamol in limb trauma and compare it with Iv Morphine sulfate.
