| Abstract |
During resuscitation, when it is difficult or impossible to establish peripheral venous access, intraosseous route (IO) is considered as an alternative to a central venous line. However, it is sometimes difficult for obtain IO access with conventional manual bone puncture needle. Recently, powered mechanical bone marrow needle was developed. We compared the performance of the manual and mechanical bone marrow puncture needle for adult, child and infant simulation. 22 anesthesiologists, who has never used bone marrow puncture needle, performed manual (Dickman™, Cook Medical) or mechanical (EZ-IO™, Teleflex) bone marrow puncture to simulated adult, child and infant tibia. Puncture success rate, insertion time, and subjective difficulty utilizing visual analogue scale was assessed. In adult settings, with the manual bone marrow needle, only 3 of 22 participants could succeed in the IO route keep, while all participants did in the mechanical bone marrow puncture needle (P < 0.001). In child and infant settings, all trials were successful in both manual and mechanical bone marrow puncture needles (P = 1.00). In adult simulations, IO insertion took significantly longer with manual bone marrow puncture (54.8 ± 15.8 s) than without compressions (3.7 ± 2.1 s; P < 0.001). In child and infant simulations, the IO insertion time was significantly smaller in mechanical trials than in manual ones (child simulation; manual 9.3 ± 4.6 s, mechanical 2.2 ± 0.8 s, P < 0.001, infant simulation; manual 2.0 ± 1.1 s, mechanical 1.5 ± 0.8 s, P = 0.003). Although the VAS score was not significantly higher with manual trials than in mechanical trials among the three simulations (adult simulation, P < 0.001, child simulation, P < 0.001, infant simulation P = 0.006). We conclude that in simulations managed by anesthesiologists who had no clinical experiences with bone marrow puncture, the mechanical bone puncture needle performed better than the manual one for emergency IO route access. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 May 2015.
All research outputs
#20,273,512
of 22,805,349 outputs
Outputs from SpringerPlus
#1,461
of 1,851 outputs
Outputs of similar age
#222,705
of 264,367 outputs
Outputs of similar age from SpringerPlus
#47
of 61 outputs
Altmetric has tracked 22,805,349 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,851 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 264,367 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 61 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
