ObjectiveTo study the value of revised trauma scores (RTS), major trauma outcome study (MTOS)-RTS scores and point of care test (POCT) in the early forecast of survival time in severe multiple trauma patients. MethodsMultiple trauma patients treated in the Emergency Department of our hospital between September and December 2015 were included in our study. We collected such data as the basic information on admission, physical signs (breath, blood pressure, state of consciousness) and POCT indexes, including pH value, hemoglobin, base excess, hematocrit value, lactic acid, sodium, anion gap, and blood glucose. We calculated each patient's RTS and MTOS-RTS scores. According to the 30-day prognosis, the patients were divided into survival group and death group. Risk factors for survival time were screened by Cox regression risk model. ResultsSeventy-five multiple trauma patients were included in our study. Among them, there were 51 males and 24 females. Fourteen of them died. The multivariate analysis in the Cox regression risk model showed that the risk factors for the death of multiple trauma patients included MOTS-RTS score [RR=0.726, 95%CI (0.608, 0.867), P < 0.001) and POCT lactic acid level [RR=1.139, 95%CI (1.010, 1.324), P=0.037]. ConclusionMOTS-RTS combined with lactic acid level may be used in the early forecast of survival time in severe multiple trauma patients.
This article discusses the new needs and development direction of medical testing technology under the hierarchical diagnosis and treatment system in China, outlines the principles and advantages of new medical testing technology based on smartphones, and briefly describes the development status and research results of smartphone testing technology in specific medical testing directions such as immune analysis, nucleic acid analysis, biochemical analysis and cell morphology analysis. In addition, the article also discusses the current problems of smartphone medical testing technology, such as poor compatibility with different models of smartphones, few detection indicators, low automation, lack of clinical verification. Finally, a prospect is made for the possible future development direction of smartphone medical examination technology, aiming to provide a certain reference for the promotion and more reasonable application of smartphone medical examination technology.
