Study Notes
Morphine DTP
- Morphine is a narcotic analgesic that acts on the central nervous system by binding with opioid receptors.
Pharmacology of Morphine
- Morphine alters pain perception and emotional response to pain, causing respiratory depression, vasodilation, and slows AV node conduction.
- Metabolized by the liver, kidney, and lungs.
Indications for Use of Morphine
- Significant pain
- Sedation
- Autonomic dysreflexia (with systolic BP > 160 mmHg)
Contraindications for Use of Morphine
- Allergy to morphine and/or adverse drug reaction to morphine
- Kidney disease (renal failure)
Precautions for Use of Morphine
- Hypotension
- Respiratory tract burns
- Respiratory depression and/or failure
- Known narcotics addiction
- Concurrent MAOI therapy (antidepressants)
- Cardiac chest pain
Side Effects of Morphine
- Bradycardia
- Drowsiness
- Hypotension
- Nausea and/or vomiting
- Pinpoint pupils
- Respiratory depression
Presentation and Administration of Morphine
- Available in ampoules, 10mg/1ml morphine sulphate pentahydrate
- Routes of administration: subcutaneous injection (SUBCUT), intramuscular injection (IM), intravenous injection (IV), and intraosseous injection (IO)
Pharmacokinetics of Morphine
- Onset of action: 5-10 minutes (IM), 2-5 minutes (IV)
- Duration of action: 1-2 hours
- Half-life: 2 hours
Special Notes for Morphine
- Ambulance officers must only administer morphine for listed indications and dosing range.
- Total maximum dose must be calculated when combining morphine with other narcotic medications.
- Morphine is suitable for treating moderate to severe labour pain in full-term mothers in the pre-hospital setting, but paramedics must carefully assess risks and benefits for both mother and child.
