Be cautious of using Fentanyl and Morphine in combination. Smaller doses will be required
If respiratory depression occurs due to narcotic administration - manage as per Overdose
Pts with undiagnosed headache (i.e. new onset sudden severe headache) cannot be given Morphine by Ambulance Paramedics without consultation with a Medical Officer at the receiving hospital. MICA Paramedics may administer Morphine or Fentanyl in this setting without consultation.
ALS Paramedics must consult prior to exceeding the 20mg max dose of Morphine and administer according to Pt need or the onset of side effects
The effect of Morphine IM on pain relief is slow and variable. This route must be used as a last resort and strictly within indicated guidelines
Do not administer IM medication if Pt is likely to receive thrombolysis
Narcotic pain relief should not be administered during late second stage of labour. If narcotics have been administered, Naloxone should not be administered to the newborn.
