Block GuRU Lite 6.0.0

GuRU is a comprehensive offline teaching application designed to provide in-depth education on single shot and continuous peripheral nerve blocks. The content, including videos and instructional materials, is accessible without the need for an internet connection.

The app features a distinctive approach that integrates live sonoanatomy via ultrasound, 3D animated anatomy visuals, and real-time video demonstrations of regional anaesthetic nerve block techniques, all synchronized with clear auditory narration.

• Full-length offline demonstrations covering various regional anaesthetic techniques.
• Detailed guidance on the insertion of a Pajunk E-Cath (CPNB).
• A comprehensive video tutorial on setting up, inserting, and fixing the Pajunk E-Cath system.
• 3D animated anatomical models linked with real-time ultrasound scans.
• Synchronized ultrasound and camera nerve mapping scans that illustrate the entire procedure from start to finish.
• Insightful narration throughout the demonstration enhances comprehension.
• A repository of practical tips and advice invaluable for those starting their journey with ultrasound-guided blocks.
• User-friendly tabs categorizing content into Anatomy, Procedure, and Tips.
• Visually striking full-screen diagrams and annotated ultrasound screenshots.
• A valuable resource for both novice and experienced anaesthesia practitioners.
• An educational tool suitable for ODPs, ODAs, anaesthetic nurses, PAs, AAs, CRNAs, and other professionals in regional anaesthesia.
• Medical students will find this app beneficial for deepening their understanding of regional anaesthesia techniques.

The app's tab system provides users with easy access to anatomy overviews, detailed procedural guides with pictorial support, and valuable tips regarding specific blocks. The Anatomy tab includes expandable schematic diagrams pertinent to each block. The Procedures tab offers a comprehensive visual and textual guide to performing each block, including annotated ultrasound images to visualize nerves effectively. The Tips tab features practical advice tied to the selected block, as well as insights into ultrasound utilization and local anaesthetic pharmacology.

This application is essential for both junior and senior anaesthetic staff as well as practitioners involved in regional anaesthesia. The various blocks covered include:

• Interscalene & Mapping
• Supraclavicular & Mapping
• Infraclavicular
• Axillary x 2 & Mapping
• Radial Nerve & Mapping
• Median Nerve & Mapping
• Ulnar Nerve & Mapping
• TAP
• Femoral Nerve & CPNB
• Saphenous Nerve
• Popliteal Sciatic
• PECS1
• PECS2
• Combined PECS1 and 2
• Serratus anterior

The inclusion of dedicated nerve mapping videos enhances the learning experience by facilitating orientation with anatomical structures through demonstrator videos linked to live ultrasound scanning. These mapping videos will be available online to reduce app size; internet access will be necessary to view this content. Users are encouraged to provide feedback regarding desired future updates.

The GuRU app serves as an informative guide rather than a replacement for traditional textbooks. It is not a substitute for a solid understanding of anatomy or local anaesthetic pharmacology; rather, it acts as an aid for occasional practitioners, a refresher for seasoned professionals, and a teaching tool for trainers in the field.

This resource is particularly beneficial in busy hospital settings where continuous teaching commitments exist. The incorporation of nerve stimulation alongside ultrasound is advocated to enhance patient safety and provide reassurance to operators during procedures.
