Summary
Computer-assisted instrument guidance (CAIG) improved simulated transversus abdominis plane (TAP) block performance in novice nurse anesthetists. The CAIG system led to fewer attempts and faster completion times compared to traditional ultrasonography.
Area of Science:
- Anesthesiology
- Medical Simulation
- Ultrasound Guidance
Background:
- Novice nurse anesthetists require effective training tools for regional anesthesia.
- Transversus abdominis plane (TAP) blocks are commonly performed ultrasound-guided procedures.
- Computer-assisted instrument guidance (CAIG) offers potential for enhanced procedural training.
Purpose of the Study:
- To evaluate if CAIG with optical tracking improves simulated TAP block performance by novice student registered nurse anesthetists (SRNAs).
- To compare CAIG-assisted ultrasonography (US) versus standalone US for simulated block efficacy and efficiency.
Main Methods:
- A crossover study design involving 26 SRNAs performing simulated TAP blocks in a porcine model.
- Participants were randomized to US-only or CAIG groups.
- Performance assessed via task-specific checklist, global rating scale, procedure time, and number of attempts.
Main Results:
- Higher global rating scale scores and overall performance in the CAIG group (P = .010).
- Significantly fewer simulated block performance times (P = .037) and insertion attempts (P = .002) with CAIG.
- No significant difference in checklist survey results between groups.
Conclusions:
- CAIG demonstrates favorable results for novice SRNAs in simulated TAP block procedures.
- CAIG enhances simulated block performance, reducing procedure time and attempts.
- A strong participant preference for the CAIG system was reported (88% enhanced experience).
