Clavicular approach to intraosseous infusion in adults

We attempted a clavicular approach to intraosseous infusion (clavicular IO) as a new procedure in adults, and compared the flow rates of subclavian venous infusion, and clavicular, iliac and tibial IO. Furthermore, we observed enhanced roentgenograms of each IO by contrast media. As a result, clavicular IO indicated 11.9 +/- 0.68 mL/kg/hr (mean +/- SD, n = 29), iliac IO 32.2 +/- 4.48 (n = 21), tibial IO 18.9 +/- 1.28 (n = 15), and subclavian venous infusion 15.2 +/- 1.48 (n = 15). There were no statistically significant differences between subclavian venous infusion and clavicular IO. In roentgenograms, the contrast media entered the inferior vena cava from iliac IO, and via the femoral vein by tibial IO. The superior vena cava was enhanced through the subclavian vein in clavicular IO. No complications such as fractures or transclavicular penetrations by the IO needle occurred. In conclusion, clavicular IO may be an alternative infusion technique to provide the fluids into the subclavian vein in adults.
