Ultrasonographic Confirmation of Intraosseous Needle Placement in an Adult Unembalmed Cadaver Model

Use of Cadaver Models in Point-of-care Emergency Ultrasound Education for Diagnostic Applications

“…Delaunoy et al and Hong et al demonstrated that injecting normal saline into cadaver joints provided a model to detect joint effusion in knees (11,12). Additionally, studies have shown that cadaver models are useful in answering important clinical questions such as the sensitivity of US to localize small soft-tissue foreign bodies and the ability of US to confirm endotracheal tube placement and intraosseous needle placement (13,14,18). As in previous studies, our study demonstrated that qualitatively, freshly frozen cadavers can be effective models for joint effusion.…”

“…Additionally, cadaver models have been used to train residents in performance of the focused assessment with sonography in trauma (FAST) examination, by simulating free intraperitoneal fluid detected on US, and for demonstrating joint effusion (10)(11)(12). There are numerous applications of diagnostic and procedural bedside US that can be simulated with human cadaver models and thus used for medical education (6)(7)(8)(9)(10)(11)(12)(13)(14)(15).…”

The use of intraosseous infusions in the operating room

“…Ultrasound may be an alternative technique for confirmation, especially when a blood flashback cannot be ascertained. In a small pilot study (n = 8) using cadavers, Stone et al [15] reported that the sensitivity and specificity of ultrasound was 100%,whereas visual examination of the tubing drip chamber had a sensitivity and specificity of 88% and 25%, respectively.…”

Bedside ultrasound in the pediatric emergency department

“…Finally, ultrasound has also been used to confirm intraosseous needle placement in adult cadavers. Stone [41] showed that ultrasound correctly identified the location of all intraosseous placements whereas examination of the intravenous tubing drip chamber for flow had 88% sensitivity and 25% specificity for correct needle position.…”
