初期波形VT・VFの心停止における体外循環式心肺蘇生(ECPR)は一定の効果が報告され,近年多くの施設で導入されつつある。初期波形PEAは原疾患が多岐にわたるためECPRの有効性は未確立であるが,肺血栓塞栓症に限れば予後良好である報告が散見される。 当院で救命に至った2例の肺血栓塞栓症ECPR症例は,呼吸困難の先行と肺雑音がないことを救急隊が認識できており,初期波形PEAで二次救命処置により自己心拍再開と心停止を繰り返す状態にあった。両症例とも救急隊からの第一報を的確に得ることで,病着前からECPRを準備し,病着後,心臓超音波検査で心タンポナーデを否定したうえで肺血栓塞栓症を念頭に置いてECPRを実施できたことで社会復帰に至った。目撃やbystander CPRがある心停止のうち,呼吸困難先行と肺雑音なしを確認した初期波形PEA症例はECPRを実施できる施設への搬送を考慮し,超音波検査で心タンポナーデが否定された場合は積極的にECPRを検討することが重要である。

Productivity, safety and its improvement is also an integral part of a good mining operation. In recent times, due to constraints on time and cost, it has become increasingly harder to conduct training and safety inductions at mine sites. For the purpose of overcoming these limitations, the use of virtual reality (VR) is proposed for mining education and training. VR has already been introduced in the education and training of miners overseas, and quantitative studies on the effects of using VR for miner's education and training have been made. However, Japan has only one such application of VR for mining education, namely, “Virtual Mining Practice System” which was produced by Akita University, and there are relatively few cases where VR has been introduced in the Japanese mining industry. Furthermore, there has been no quantitative study to date on the effects of education using VR for mining education. Therefore, the objective of this study is to investigate the effects of a class that utilizes a VR application developed for mining education (Mining VR), as well as evaluate its learning outcomes. In this study, a method called randomized controlled trial (RCT) is used for evaluating Mining VR's effectiveness. Study participants are divided two groups randomly where one class makes use of Mining VR and another class using other non-VR material. After the classes are completed, a test is conducted and the average results of each group are compared by T-test. The results of this experiment showed that there were no statistically significant differences in skill of “understanding” and “knowledge retention” comparing two groups. On the other hand, results suggested that Mining VR has improved students'“ motivation” for class when using Mining VR.
