Study Notes
Analgesics Overview
- Analgesics are medications designed to alleviate pain.
- Types include narcotics, anaesthetics, and local agents.
Narcotics
- Primarily used for severe pain relief.
- Act on the central nervous system (CNS) to produce analgesic effects.
Anaesthetics
- Induce a loss of sensation or consciousness during medical procedures.
- Can be general or regional; effects vary based on usage.
Mode of Administration
- Routes include oral, intravenous, intramuscular, spinal, and topical.
- Mode affects onset time and effectiveness of the drug.
Indications
- Indicated for conditions such as surgery, severe pain, and chronic pain management.
Dosages
- Dosages vary widely based on the drug type and patient condition.
- Requires careful calculation to prevent underdosing or overdosing.
Action
- Analgesics function by blocking pain signals in the brain or through the nervous system.
Contraindications and Antidotes
- Narcotics contraindicated in patients with respiratory issues or history of substance abuse.
- Antidotes, such as naloxone, are available for narcotic overdose.
Interaction, Side Effects, and Allergies
- Drug interactions can potentiate effects or cause adverse reactions.
- Common side effects include nausea, drowsiness, and constipation.
- Allergic reactions can occur and require immediate attention.
Overdosage
- Overdosage of analgesics can lead to severe respiratory depression, coma, or death.
- Requires prompt medical intervention.
Elimination
- Drugs are primarily eliminated through liver metabolism and renal excretion.
Complications
- Potential complications include infection, nerve damage (from regional anaesthesia), and prolonged sedation.
General Agents: Muscle Relaxants and Reversal Agents
- Muscle relaxants facilitate surgical procedures by relaxing skeletal muscles.
- Reversal agents are used to counteract the effects of certain anaesthetics, returning muscle function.
Regional Agents - Anesthesia Types
- Spinal: An injection into the spinal canal to provide pain relief.
- Epidural: Delivered outside the spinal cord to manage pain during labor or surgery.
- Brachial: Nerve block for pain management in the upper limb.
Local Agents
- Xylocaine and Lidocaine: Local anaesthetics used for minor procedures. Lidocaine may be used with adrenaline to prolong effects.
- Effective for targeted pain relief without systemic effects.
Other Forms
- Intravenous infusions help maintain consistent drug delivery.
- Antiseptic solutions reduce infection risk during treatments.
Drug Nomenclature and Classification
- Important for identifying drug families and their uses within essential healthcare services.
- Essential drug policy ensures availability of fundamental medications.
Drug Action and Interactions
- Understanding how drugs interact within the body is crucial for effective treatment plans.
- Factors influencing drug action include absorption, distribution, metabolism, and elimination.
Drug Calculations; Weights and Measures
- Accurate calculations are vital for safe administration.
- Medical professionals must be adept in converting units and calculations.
Unit II: Drug Administration
- Methods include oral, parenteral, and topical, each with distinct benefits.
- Responsibilities of perioperative nurses encompass proper handling from ordering to documentation.
Drug Abuse Issue in Nigeria
- Drug abuse poses significant healthcare challenges, necessitating improved regulation and education efforts.
