This randomized controlled trial evaluated the accuracy of point-of-care ultrasound (POCUS) in identifying standard bougie (SB) versus wire-core bougie (WCB) placements in cadaver models. Among 112 matched pairs analyzed, the WCB showed a higher identification accuracy of 98% compared to 89% for the SB, with a statistically significant difference (P=.006), though not clinically meaningful.
Key findings
- Identification accuracy was 98% for WCB versus 89% for SB (P=.006).
- WCB demonstrated superior sensitivity of 96% compared to 92% for SB.
- WCB had a specificity of 100%, while SB's specificity was 86%.
- Median time to identification was similar: 3.3 seconds for SB and 3.4 seconds for WCB.
Why it matters
Understanding the effectiveness of different bougie types in airway management can enhance training and improve outcomes in emergency situations. Accurate identification of bougie placement is crucial for successful intubation.
