Central Venous Access Course

Lesson 1 • Catheter Types and Selection Criteria

Surveys single-lumen, multi-lumen, introducer, and specialty catheters with selection rationale. Connects device characteristics to clinical goals established in prior sections.

Lesson 2 • Regulatory and Ethical Framework

Outlines informed consent, competency credentialing standards, and institutional oversight requirements. Establishes the professional accountability context for all procedural chapters.

Lesson 3 • Anatomy of Central Venous Structures

Covers the course, relationships, and landmarks of the internal jugular, subclavian, and femoral veins. Provides the anatomical map essential for safe needle trajectory decisions.

Lesson 4 • Indications and Contraindications

Defines clinical scenarios requiring central venous access and conditions that modify or preclude placement. Grounds procedural decisions in evidence-based patient selection criteria.

Lesson 1 • Central Line Bundle Compliance

Presents the evidence-based insertion bundle elements and the role of a checklist observer. Connects individual technique to system-level CLABSI prevention outcomes.

Lesson 2 • Catheter Maintenance and Dressing Care

Describes dressing change intervals, securement devices, and hub disinfection protocols post-insertion. Extends infection prevention beyond placement to the full catheter dwell period.

Lesson 3 • Principles of Surgical Asepsis

Defines the sterile field, contamination pathways, and behavioural rules governing aseptic technique. Forms the behavioural foundation for every procedural step that follows.

Lesson 4 • Skin Antisepsis and Site Preparation

Covers antiseptic agent selection, application technique, and required contact time for central line sites. Ensures learners achieve effective microbial reduction before needle insertion.

Lesson 1 • Short-Axis and Long-Axis Needle Visualization

Teaches in-plane and out-of-plane needle approaches with real-time tip tracking strategies. Prepares learners for the specific imaging views used in each access site chapter.

Lesson 2 • Transducer Handling and Sterile Probe Technique

Covers sterile probe cover application, gel use, and ergonomic transducer positioning during procedures. Integrates aseptic principles from Chapter 2 into ultrasound-guided workflows.

Lesson 3 • Ultrasound-Guided Venepuncture Practice

Applies imaging skills to simulated venepuncture on phantoms before live patient procedures. Consolidates all ultrasound fundamentals into a supervised hands-on performance checkpoint.

Lesson 4 • Vascular Sonoanatomy Identification

Trains recognition of veins versus arteries using compressibility, pulsatility, and Doppler signals. Builds on anatomical knowledge from Chapter 1 with real-time imaging correlation.

Lesson 1 • Guidewire Properties and Handling

Describes J-tip, straight-tip, and stiff wire designs, and their appropriate clinical applications. Ensures learners select and handle wires safely to prevent vessel injury.

Lesson 2 • Seldinger Technique Step-by-Step

Breaks down needle insertion, wire passage, dilation, and catheter threading into discrete, sequenced steps. Establishes the procedural template applied at every access site in later chapters.

Lesson 3 • Dilation and Tract Creation

Covers dilator sizing, insertion force, and depth limits to create an adequate tract without vessel injury. Prepares learners for the tactile feedback expected during dilation at each site.

Lesson 4 • Wire-Related Complications and Prevention

Identifies arrhythmia, wire embolism, and vessel perforation risks tied to wire mismanagement. Equips learners with prevention strategies and immediate corrective responses.

Lesson 1 • Ultrasound Survey of the Internal Jugular Vein

Applies Chapter 3 scanning skills to map IJ vein size, patency, and relationship to the carotid artery. Pre-procedural survey findings directly guide needle entry point selection.

Lesson 2 • Catheter Depth and Tip Positioning

Provides depth estimation formulas for right and left IJ approaches and expected catheter tip location. Accurate depth placement reduces malposition rates before radiographic confirmation.

Lesson 3 • IJ-Specific Complications and Management

Addresses carotid artery puncture, hematoma, pneumothorax, and air embolism risks unique to the IJ site. Learners apply immediate management steps and escalation criteria.

Lesson 4 • Needle Insertion and Venipuncture Technique

Guides real-time ultrasound-directed needle advancement into the IJ lumen using short-axis and long-axis views. Integrates Seldinger technique from Chapter 4 into the IJ-specific workflow.

Lesson 1 • Site Comparison and Clinical Decision-Making

Synthesizes infection risk, complication profiles, and patient factors to guide site selection across all three access sites. Prepares learners for individualized procedural planning in Chapter 7.

Lesson 2 • Subclavian Venipuncture Technique

Details needle angle, clavicle contact, and wire passage for infraclavicular subclavian access. Applies Seldinger technique from Chapter 4 with subclavian-specific tactile and imaging cues.

Lesson 3 • Femoral Vein Anatomy and Access Technique

Covers femoral triangle anatomy, NAVEL mnemonic, and ultrasound-guided femoral venipuncture steps. Femoral access serves as an alternative when upper-body sites are contraindicated.

Lesson 4 • Subclavian Complications and Prevention

Focuses on pneumothorax, hemothorax, and subclavian artery injury as the dominant subclavian risks. Learners apply prevention strategies and recognize early complication signs.

Lesson 1 • Arterial Puncture and Cannulation Management

Provides a stepwise response to inadvertent arterial puncture, including needle versus dilator versus catheter scenarios. Arterial cannulation is the most immediately dangerous mechanical complication.

Lesson 2 • Air Embolism and Thrombotic Complications

Addresses air embolism prevention, Durant maneuver, and catheter-related thrombosis diagnosis and treatment. Completes the complication management framework before advanced practice chapters.

Lesson 3 • Chest Radiograph Interpretation for CVC Placement

Teaches identification of catheter tip position, pneumothorax, and hemothorax on post-procedure chest X-ray. Radiographic confirmation is the standard endpoint of every central line insertion.

Lesson 4 • Catheter Malposition Recognition and Correction

Identifies common malpositions including contralateral subclavian, internal mammary, and right atrium placements. Learners apply wire-guided repositioning and escalation criteria.

Lesson 1 • Central Venous Access in Paediatric Patients

Adapts site selection, catheter sizing, and ultrasound technique to neonatal, infant, and paediatric anatomy. Paediatric physiology and smaller vessel calibre require modified procedural approaches.

Lesson 2 • Access in Critically Ill and Hemodynamically Unstable Patients

Adapts procedural workflow for patients on vasopressors, mechanical ventilation, or with elevated ICP. Urgency and physiological instability require modified technique and team coordination.

Lesson 3 • Access in Obese and Anatomically Challenging Patients

Covers ultrasound optimisation, longer needle selection, and positioning modifications for obese patients. Anatomical distortion increases procedural difficulty and complication risk.

Lesson 4 • Tunneled and Implanted Device Considerations

Introduces tunneled catheter and implanted port placement principles as extensions of standard CVC technique. Learners recognise when long-term access devices are indicated over short-term catheters.
