Ultrasound has become an indispensable tool for anesthesiologists, particularly for performing peripheral nerve blocks. It offers real-time guidance, which allows for greater accuracy, reduced complications, and improved patient outcomes.
Dr. Rudiger Eichholz, a seasoned anesthesiologist, recently shared his insights and experience on the benefits of using ultrasound for anesthesia procedures during a webinar, which is now available to watch on-demand: Mastering Ultrasound-Guided Procedures: 3 Pillars for Safety and Success.
Read-on for some key takeaways and tune it to watch his demonstrations.
Understanding the Benefits of Ultrasound Guidance
Ultrasound guidance offers numerous advantages over traditional blind injections. These include:
- Faster onset of sensory and motor block.
- Reduced performance time.
- Fewer needle passes.
- Decreased risk of local anesthetic systemic toxicity (LAST).
- Reduced intensity of diaphragmatic paresis.
By using ultrasound, anesthesiologists can enhance the precision and safety of their procedures, leading to better patient outcomes.
Three Pillars for Safe and Successful Ultrasound-Guided Procedures
Dr. Eichholz emphasizes three key pillars for mastering ultrasound-guided procedures:
- Probe Handling: This involves manipulating the ultrasound probe to optimize needle visibility. Techniques include tilting, rotating, and swinging the probe in micro-movements to ensure the needle tip is always within the scanning plane.
- Needle Control: The needle itself can be used to enhance visibility. This includes directing the bevel upwards for better sound reflection and inserting the needle at a shallow angle for improved visualization. Rotating the needle can also help identify the tip and penetrate fascial layers.
- Sonographic Anatomy: A thorough understanding of sonographic anatomy is crucial. Standardized scanning procedures can help identify the correct location for needle placement.
Additional Considerations for Successful Ultrasound-Guided Procedures
Beyond the three pillars, several other factors contribute to the success and safety of ultrasound-guided procedures:
- Training and Practice: Attending training courses and practicing on phantoms can significantly improve anesthesiologists’ skills in using ultrasound.
- Needle Navigation: Techniques like angle navigation and the walk-down method with angle adjustment can help guide the needle to the target structure accurately.
- Syringe Control: The anesthesiologist should control the syringe to ensure precise injection and avoid accidental over injection.
- Guidewire Control: Guidewires can be used to enhance needle visibility and control during vascular access procedures.
- Catheter Control: Ultrasound can also be used to confirm the proper placement of catheters.
Handheld Ultrasound: A Valuable Tool for Anesthesiologists
Dr. Eichholz uses the Clarius PAL dual-array scanner, which provides clear visualization of relevant anatomy and facilitates precise needle placement.
