Objective To investigate the joint value of early peak temperature and 48 h-△sequential organ failure assessment (SOFA) score in predicting the prognosis for patients with sepsis in emergency department.Methods Two hundred and thirty-one patients with sepsis admitted from January 2013 to January 2015 in Emergency Intensive Care Unit of the First Affiliated Hospital of China Medical University were enrolled.Clinical features,early peak temperature,SOFA scores,the length of stay in EICU and the mortality in 28 days were studied.The patients were divided into two groups according to the 48 h-△SOFA.Each group were divided into three subgroups according to the early peak temperature.For example,hypothermia subgroup had temperature below 36 ℃,normothermia subgroup had temperature between 36 ℃ and 38 ℃,and hyperthermia subgroup had temperature above 38 ℃.The relationship between peak temperature plus 48 h-△SOFA and the length of stay in EICU as well as mortality were analyzed.Results Of 231 patients,in 48 h-△SOFA＞0 group (n =142) 27 (19.0％) patients died,and in 48 h-△SOFA≤0 group (n =89) 33 (37.1％) patients died (P ＜ 0.05).Hypothermia subgroup had a higher odds ratio value in predicting nonsurvival in 48 h-△SOFA≤0 group (OR =4.51,95％CI:1.33-2.17,P =0.01).Hyperthermia subgroup had a longer stay in EICU than hypothermia subgroup and normothermia subgroup (P ＜ 0.05).Conclusion The combination of the early peak temperature and 48h-△SOFA score is an effective indicator to evaluate the prognosis and to stratify patients with sepsis in emergency department.More attention should be paid to the patients with an early peak temperature ＜ 36 ℃ and 48 h-△SOFA ≤0 because of higher mortality.The condition of patients should be reassessed and try to make a more rational treatment for the patients with an early peak temperature ＞38 ℃ and 48 h-△SOFA ＞0 because of its longer stay in EICU.

Objective To investigate the clinical value of combining early urine paraquat early clearance rate (UPCR) with severity index of paraquat poisoning (SIPP) in predicting the prognosis for paraquat poisoning patients.Methods In this retrospective research,a total of 425 cases diagnosed with acute paraquat poisoning from March 2014 to March 2016 in Emergency Intensive Care Unit,First Affiliated Hospital of China Medical University were enrolled.The general data of patients,the results of rapid qualitative test of paraquat in blood and urine,the concentration of paraquat in blood / urine,the poisoning time,the concentration of blood lactic acid and the APACHE Ⅱ score were collected.The early UPCR and SIPP were measured at different time intervals,and the ratio of 6-SIPP and 12 h-UPCR were calculated.These patients were divided into death groups and survival groups according to the 28-day mortality.The relationship between these factors and the mortality were analyzed.Results Of all the 425 patients,268 cases (63.1％) died,157 cases (36.9％) survived;the blood concentration of paraquat,the lactate concentration,SIPP values and the APACHE Ⅱ scores were significant difference between the two groups (P ＜ 0.05).The mortality of 2-6 hour paraquat rapid qualitative test result positive patients was higher (96.4％) than that of the negative patients (3.6％) (P ＜ 0.05);the mortality of 12-24 hour paraquat rapid qualitative test result negative patients was lower (11.5％) than that of the positive patients (88.5％) (P＜0.05).The 2-6 hour SIPP value was 19.8 ±6.7 in death group,which was higher than that in survival group (4.9±3.1) (P＜0.05);the 2-6 hour UPCR value was (41.7±9.3) indeath group,which was lower than that in survival group (86.3 ± 15.8) (P ＜ 0.05).There was no significant difference in the 2-6 hour UPCR value and 12-24 hour UPCR value between two groups (P ＞0.05).The 6 h-SIPP/12 h-UPCR value was (41.94 ±5.9) in death group,which was higher than that in survival group (5.27 ± 3.6) (P ＜ 0.05).Conclusion The combined use of early UPCR and SIPP values is an effective indicator of the prognosis of patients with acute paraquat poisoning and is helpful for the early stratification.We should pay more attention to the patients whose rapid qualitative blood test is positive because of their high mortality risk;for the patients whose 12 h urinequalitative test was negative,the hemoperfusion therapy might be stopped because the toxin was completely excluded,and the medical resources can be saved reasonably.The UPCR might indicate the excretion of toxins,and SIPP might indicate the severity of poising.
