The study cohort exhibits several unique features, including a delay in arrival to medical care, paucity of prior care and information, and the specific mechanisms of injury. Our study suggests that Advanced Life Support providers do not differ significantly in Role 1 treatment choices and procedure success.

Since the late 1600's medicine and science have entertained the idea of extracorporeal circulation. With this technology to allow for cardiac and pulmonary support came the development of anticoagulation. Although this advanced the technology and capabilities of extracorporeal life support, it was not without complications and risks. The most common complications in extracorporeal life support (ECLS) present day are related to hemorrhage and thrombus due to the need for systemic anticoagulation and the challenges associated with it. This review focuses on present day techniques for anticoagulation for ECLS and what future surface modifications may do to obviate the use of systemic anticoagulation entirely.

Background:No study has examined the performance of emergency department (ED) nurses in establishing intraosseous access (IO) access. This study aimed to evaluate ED nurses' success rate in establishing pediatric IO access using semiautomatic devices. Methods:A randomized crossover simulation study was conducted. The success rates of ED nurses were compared with those of paramedics with similar years of experience. The study instruments were the new springloaded injector (NIO) and the battery power drill (EZ-IO). Uncooked piglets' bones were used as the study model. All attempts were filmed by a video camera. Successful placement was defined as the visualization of flow from the marrow cavity. Participants recorded their ranking of the "ease of use" of each device.Results: No differences in 1-attempt success rate was found between nurses and paramedics (27/34 [79.4%] vs 25/30 [83.3%], P = 0.68). Nurses and paramedics had similar success rates with the 2 semiautomatic IO devices (12/17 vs 12/15 with the spring-loaded injector, P = 0.69, and 15/17 vs 13/15 with the battery power drill, P = 0.9). The number of failed attempts and the causes for failure were equally distributed between nurses and paramedics. Median ease-of-use Likert-scale scores of the springloaded injector and the battery power drill were 4 (interquartile range [IQR] = 3-4) and 5 (IQR = 5-5) (P < 0.04) for the nurses and 5 (IQR = 4-5) and 5 (IQR = 4-5) (P = 0.44) for the paramedics, respectively.Conclusions: Emergency department nurses and paramedics had a similarly high insertion success rates on a pediatric bone model. This pilot study suggests that ED nurses can successfully perform this procedure.
