Study Notes
Analgesia
- Opioids are the primary choice for managing severe surgical pain, used both pre- and post-operatively
- Examples of opioids include morphine and fentanyl
- Post-operative side effects of opioids include:
- Constipation
- Urinary retention
- Respiratory depression
- Nausea and vomiting
Muscarinic Antagonists
- Prevent excessive cholinergic effects, such as:
- Salivation
- Bronchial secretions
- Protect the heart from arrhythmias caused by certain anesthetics, such as halothane
- Examples of muscarinic antagonists include:
- Atropine
- Hyoscine
Antiemetic Drugs
- Prevent post-operative vomiting
- Examples of antiemetic drugs include:
- Metoclopramide
- Prochlorperazine
Neuromuscular Blockers
- Prevent reflex-induced muscle contractions, particularly for:
- Abdominal surgery
- Thoracic surgery
- Facilitate tracheal intubation
- Mechanism of action: block synaptic transmission at the neuromuscular junction by targeting nACh receptors
