Block GuRU 6.0.1

GuRU is a comprehensive offline educational application dedicated to the teaching of single-shot and continuous peripheral nerve blocks. All instructional videos and information are accessible within the app without requiring an internet connection, although internet access is necessary for accessing external links and tertiary video content.

The platform offers an innovative integration of live sonoanatomy through ultrasound imaging, 3D animated anatomical representations, and real-time video demonstrations of regional anaesthetic nerve blocks. These elements are synchronized with clear audio narration, providing a cohesive learning experience.

Features include full-length offline demonstrations of various regional anaesthetic techniques, and a detailed guide to the Pajunk E-Cath system—including setup, insertion, and fixation procedures. The app also offers interactive 3D animated models linked directly with live ultrasound scans and video recordings, as well as synchronized ultrasound and camera nerve mapping scans.

Users can observe an entire nerve block procedure from initiation to completion, accompanied by expert narration. The app functions as a valuable resource for tips and best practices, many of which would have been beneficial to have at the outset of ultrasound training.

• Intuitive tabs for Anatomy, Procedures, Tips, and Equipment facilitate easy navigation.
• Full-screen diagrams enhance visual understanding.
• Annotated ultrasound images assist in identifying nerves and relevant structures.
• An excellent resource for both novice learners and experienced practitioners in anaesthesia.
• Suitable for a range of healthcare professionals including Operating Department Practitioners (ODPs), Operating Department Assistants (ODAs), anaesthetic nurses, Physician Associates (PAAs), Anaesthesia Assistants (AAs), Certified Registered Nurse Anesthetists (CRNAs), and all staff involved in regional anaesthesia.
• Medical students can benefit from a clearer understanding of regional nerve blocks.

The app’s tab-based system allows users to access specific content areas easily:

• The Anatomy tab provides detailed overviews with expandable schematic diagrams related to each block.
• The Procedures tab offers comprehensive pictorial and text instructions, including annotated ultrasound images that enhance nerve visualization.
• The Tips tab delivers practical advice encompassing ultrasound techniques and local anaesthetic considerations.

This application is an essential tool for both junior and senior anaesthetic practitioners, as well as healthcare providers operating within regional anaesthesia practices. It covers various nerve blocks such as:

• Interscalene & Mapping
• Supraclavicular & Mapping
• Infraclavicular
• Axillary x 2 & Mapping
• Radial Nerve & Mapping
• Median Nerve & Mapping
• Ulnar Nerve & Mapping
• TAP
• Femoral Nerve & CPNB
• Saphenous Nerve
• Ppopliteal Sciatic
• PECS1
• PECS2
• Combination of PECS1 and PECS2
• Serratus Anterior

The dedicated nerve mapping videos further facilitate anatomical orientation. By integrating demonstrator videos with live ultrasound annotations, users can better locate and trace nerves and surrounding structures. These videos are available online—an internet connection is required but this feature reduces the app’s size significantly.

Future updates will include additional nerve blocks; user feedback on desired new features or techniques is welcomed via contact on www.raguru.com.

This application acts as a practical guide rather than a replacement for comprehensive textbooks. It does not substitute for a solid foundational knowledge of anatomy and pharmacology but functions well as a reference tool for occasional use, refresher training, or instructional support. Given the demands of a busy hospital environment, our team prefers using nerve stimulation alongside ultrasound to enhance patient safety and operator confidence.
