Application of copeptin and APACHE in assessment of acute paraquat poisoning / 实用医学杂志

ABSTRACT

Objective To study the value of copeptin and APACHE Ⅱ used for assessing acute paraquat poisoning (APP). Methods One hundred and twenty six APP patients were divided into survival group (n = 58) and death group (n = 68), with clinical death as the endpoint of observation. 3 mL blood was obtained from each subject at 2 h , 24 h and 7 d after admission for detecting the levels of copeptin , and APACHE Ⅱ scores were recorded at the same time. Results There was significant difference in dosages of paraquat taken in the death group and the survival group , but the differences were significant in the rescue time , the first time for hemoperfusion and the times for hemoperfusion. 2 h after admission , the death group and survival group had significant difference in elevated copeptin but no significant difference in scores by APACHE Ⅱ. 24 h after admission copeptin decreased to normal level in the survival group but maintained at a higher level in the death group, while the scores by APACHE Ⅱ had insignificant difference between two groups. 7 d after admission, copeptin kept at a higher level and the scores by APACHE Ⅱwere significantly increased in the death group , with significant differences compared to the survival group. The oral doses of pesticides the patients took were positively correlated with copeptin level and scores by APACHE Ⅱ. Conclusion Repeated detection of copeptin and APACHE Ⅱ score are of clinical importance for the assessment of prognosis of APP patients and reasonable distribution of medical resources.
