Study Notes
Analgesia in Surgery
- Opioids are the primary choice for managing severe surgical pain due to their effectiveness.
- Morphine and fentanyl are two commonly used opioids in pre- and post-operative care.
Post-Operative Side Effects of Opioids
- Constipation is a common side effect of opioid use in post-operative care.
- Urinary retention is another potential side effect of opioid use in post-operative care.
- Respiratory depression can occur as a result of opioid use in post-operative care.
- Nausea and vomiting are additional side effects of opioid use in post-operative care.
Muscarinic Antagonists in Anesthesia
- Muscarinic antagonists prevent excessive cholinergic effects, such as salivation and bronchial secretions, during anesthesia.
- Atropine and hyoscine are examples of muscarinic antagonists used in anesthesia.
- Muscarinic antagonists also protect the heart from arrhythmias caused by certain anesthetics, such as halothane.
Antiemetic Drugs in Post-Operative Care
- Antiemetic drugs, such as metoclopramide and prochlorperazine, are used to prevent post-operative vomiting.
