1Validating a point of care lactate meter in adult patients with sepsis presenting to the emergency department of a tertiary care hospital of a low-to middle-income country显示文摘BACKGROUND: Timely identifi cation of high blood lactate levels in septic patients may allow faster detection of those patients requiring immediate resuscitation. Point-of-care(POC) testing is being increasingly utilized in the emergency department(ED). We examined the accuracy and timesaving effect of a handheld POC lactate device for the measurement of fingertip and whole blood lactate as compared with reference laboratory blood testing in septic ED patients.METHODS: A convenience sample of adult ED patients receiving serum lactate testing were enrolled prospectively in the ED of a multidisciplinary tertiary care hospital serving the population of one of the major cities of Pakistan. Participants underwent fi ngertip POC lactate measurement with a portable device and simultaneous whole blood sampling for analysis by both the POC lactate device and standard laboratory method. Lactate measurements were compared by intraclass correlation(ICC) and Bland and Altman plots.RESULTS: Forty-three septic patients were included in the study. The fingertip POC & whole blood POC lactate measurements each correlated tightly with the reference method(ICC=0.93 & ICC=0.92, respectively). Similarly at 6 hours, the fingertip POC & whole blood POC lactate measurements demonstrated satisfactory correlation with the reference method(ICC=0.95 & ICC=0.97, respectively).CONCLUSION: Fingertip POC lactate measurement is an accurate method to determine lactate levels in septic ED patients.KEY WORDS: Sepsis; Point of care; Lactate; Emergency department;Muhammad Akbar Baig Hira Shahzad Erfan Hussain Asad Mian 2017World Journal of Emergency Medicine2017,8,3:7
2全科医疗在缓解急诊科拥挤现象中的作用的研究进展显示文摘随着社会对急诊医疗资源需求的不断增大,急诊科拥挤现象日益加剧。由此会产生医疗质量下降、患者满意度下降、突发公共卫生事件应急能力下降等不良后果。把符合条件的急诊就诊患者向全科医生'分流'将是缓解急诊科拥挤的重要策略之一。本文对全科医疗在缓解急诊科拥挤现象中所起作用进行综述,以期由国情出发为缓解我国急诊科拥挤现象提供新的思路。吴萌 王黛黛 马青变 2017中国全科医学2017,20,B12:1
