Objective: To perform a meta-analysis of observational studies addressing whether Dispatcher Assisted Cardiopulmonary Resuscitation (DACPR), compared with independent Bystander Cardiopulmonary Resuscitation (BCPR), increases the rates of BCPR, and whether they alter survival outcomes in out-of-hospital cardiac arrests (OHCA). Methods:Relevant published articles from PubMed and Cochrane databases were studied. The baseline information and outcome data (BCPR rates, survival to hospital discharge, 1-month survival) were extracted from the out-of-hospital cardiac arrest subgroup. Meta-analyses were performed by using STATA 11.0 software. Results Conclusion:This study found that DACPR resulted in greater survival rate as compared to independent BCPR and no BCPR in OHCAs. Considering that DACPR also resulted in significantly higher rates of BCPR, DACPR should be a standard protocol for EMS systems worldwide.
Purpose: Spondylolisthesis is a common cause of surgery in patients with lower back pain. Although inter body fusion and circumferential fusion are a relatively common surgical method for the treatment of spondylolisthesis, we retrospectively compared surgical reduction or fusion in situ with simple lumbar inter body fusion (PLIF/TLIF) and circumferential fusion (PLF+TLIF/PLIF) for adult isthmic spondylolisthesis in terms of surgical invasiveness, clinical and radio graphical outcomes, and complications. Methods: From January 2013 to June 2015, 84 adult patients with isthmic spondylolisthesis who underwent surgical treatment in our department were randomized to simple lumbar inter body fusion (PLIF/TLIF) group (group 1, n=45) and circumferential fusion (PLF+TLIF/PLIF) group (group 2, n=39), and followed up for average 28.6 months (range 24-54 months). All patients of both groups had low back pain as their predominant symptom, with varying degree of radicular pain and neurological symptoms. The data collected retrospectively for analysis were: duration of symptoms, levels of fusion, revision surgery, clinical and radiographic results after surgery, and complications. Result: All the 84 patients compared in two surgical approaches for IS were included in this retrospective studies. In our analysis, for the surgical management of isthmic spondylolisthesis, we indicated that both approaches lumbar inter body fusion (PLIF/TLIF) and circumferential fusion (PLF+TLIF/PLIF) have equal significant, greater fusion rates with successful clinical outcomes
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
