Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of a new screw-tipped intraosseous needle versus a standard bone marrow aspiration needle for infusion.
The purpose of this study is to compare the speed and ease of establishing intraosseous infusion using a standard bone marrow needle (SBMN; $8) and a new screw-tipped intraosseous needle (Sur-Fast; $42). The study is an experimental design. A total of 42 medical students, without prior IO experience, were recruited as study subjects. ⋯ VAS difficulty scores were lower (easier) for the SBMN for both inexperienced and experienced trials. Success rates were significantly higher for the Sur-Fast needle during the experienced attempt (95% versus 79%, P < .05), but there was no significant difference in success rates during the inexperienced attempt. The Sur-Fast screw-tipped intraosseous needle does not show superiority over the SBMN in this intraosseous model, therefore its higher cost is difficult to justify based on this study.

Randomized Controlled Trial Comparative Study Clinical Trial
Intraosseous is faster and easier than umbilical venous catheterization in newborn emergency vascular access models.
The purpose of this study is to compare the speed and ease of establishing newborn emergency vascular access using intraosseous (IO) versus umbilical venous catheterization (UVC). The study is an experimental design. A total of 42 medical students, without prior IO and UVC experience, were recruited as study subjects. ⋯ Although UVC may be preferred by neonatologists, this model suggests that IO results in easier and more rapid vascular access in those who do not frequently perform newborn resuscitation. As such, the benefit of teaching UVC in pediatric resuscitation courses should be reconsidered. The recommended method of emergency newborn vascular access should be reconsidered pending further studies on this subject.
