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.
Acute carbon monoxide poisoning is a common and frequently occurring disease in winter and spring in China, with high disability and mortality. Delayed encephalopathy is a serious sequela after the pseudo-convalescence. Its mechanism is complex, including environmental and genetic factors, hypoxia and energy metabolism disorder, cytotoxicity and oxygen free radical damage, immune disorder and inflammatory activation, neurotransmitter disorder, brain parenchymal changes, vascular and hemorheological abnormalities, calcium overload, and cell apoptosis. At present, methods for predicting delayed encephalopathy in acute carbon monoxide poisoning include detailed inquiry of medical history, laboratory examination of relevant indicators, electrophysiological examination, brain imaging examination, and evaluation scale prediction. This review summarizes the research status of the pathogenesis and early prediction methods of delayed encephalopathy in acute carbon monoxide poisoning, with a view to providing reference for future research directions.
