Unit 1484: Anaesthesia Techniques and Management

1. Introduction to Anaesthesia Techniques

• Overview of anaesthesia in medical procedures
• Goals of anaesthesia: analgesia, amnesia, muscle relaxation, unconsciousness
• Types of anaesthesia: general, regional, local, sedation
• Role and responsibilities of the anaesthetist

2. General Anaesthesia

2.1 Mechanism of Action

• CNS depression and unconsciousness
• Effects on respiratory and cardiovascular systems

2.2 Administration Methods

• Inhalational agents
• Intravenous agents
• Balanced anaesthesia

2.3 Monitoring During General Anaesthesia

• Vital signs: ECG, blood pressure, oxygen saturation
• Depth of anaesthesia monitoring (e.g., BIS)
• Airway management techniques

2.4 Potential Side Effects and Complications

• Postoperative nausea and vomiting
• Respiratory depression
• Cardiovascular instability

3. Regional Anaesthesia
