Description

Clinically Relevant Anatomy

CentraLineMan features clinically relevant landmarks and anatomy; learners can practice performing full catheterization using ultrasound guided or blind/landmark insertion approaches at the subclavian, supraclavicular, and internal jugular access sites. CentraLineMan includes clinically relevant internal and external landmarks that are palpable and or visible under ultrasound. These include:

Upper torso and neck
Trachea
Clavicle
Sternal notch
Sternocleidomastoid muscle
Sternal and clavicular heads of the sternocleidomastoid muscle
Manubrium
Lateral border of the first rib
Superior vena cava
Upper lung
Vascular Anatomy including: External Jugular, Internal Jugular, Subclavian, Axillary, and Brachiocephalic Veins; Carotid and Subclavian artery

Skill Development

Practice full central venous catheterization using ultrasound guided or blind/landmark insertion approaches at the subclavian, supraclavicular, and internal jugular access sites.
Practice placing patient in appropriate position per access site standards
Gain experience in identifying and selecting appropriate access site based on patient anatomical variations
Practice use of ultrasound for:
- Developing psychomotor skills required for obtaining visualization during cannulation
- Detecting anatomical variations
- Distinguishing vessels
- Visualizing arterial pulse and venous compression
- Identifying anatomical location of target vessel
- Visualizing needle cannulation of target vessel in transverse view
- Visualize threading of guidewire in longitudinal axis view
- Visualizing catheter placement
- Reducing rate of mechanical complications due to anatomical variances such as: pneumothorax or arterial puncture.
- Improving first cannulation success and decreasing needle passes
Practice palpating external landmarks to identify vessel location
Practice identifying unsuccessful vessel access by fluid feedback representing arterial puncture
