Head injury is a traumatic , painful condition requiring analgesic.
Morphine in opoid analgesic.
1-It depresses respiratory drive.slowing of respiration leads to retention of co2
which will lead to increased intracranial tension.Head injury itself increases intracranial tension.
2-Raised intracranial tension leads to vomiting. Morphine also stimulates CTZ , LEADING TO nausea and vomiting.
3–Head injury assessment is done by pupillary constriction /dilataion.
Morphiune interferes wih this assessment/prognosis because it causes pupillary miosis- constriction of pupil.
