Predictive Value of The Combined Detection of Platelets, D-Dimer, and Procalcitonin On Severe Heat Stroke

Abstract

BackgroundTo explore the clinical characteristics of patients with severe heat stroke, we explored the early sensitive indicators of heat stroke (HS) patients, with a view to early intervention for HS patients. MethodsFrom July 30, 2015 to October 5, 2020, 70 inpatients with severe heat stroke admitted to the Second Affiliated Hospital of Nantong University, Jiangsu Province were selected as the research objects. The general information and clinical test indicators of the patients were recorded, and all patients were assessed for acute physiology (APACH Ⅱ) upon admission. According to the severity of heatstroke, they were divided into three groups: control group (heat cramps and heat exhaustion), EHS, and CHS to compare the differences in indicators of each group. Further draw the receiver operating characteristic curve (ROC).Results1. According to the severity of heat stroke, 28 cases were divided into the control group, 24 cases in the EHS group, and 18 cases in the CHS group. The body temperature of the EHS group and the CHS group was significantly higher than that of the control group (both P<0.05), but there was no statistical difference in the body temperature of the EHS group and the CHS group; the DD, PCT, and APACH of the EHS group were significantly higher than those of the control group and the CHS group (both P＜0.05); PLT, CRP, Na, GLU of EHS group were lower than those of control group and CHS group (all P＜0.05), and the decrease of PLT was more significant; CHS group HbA1C was significantly higher than that of control group and EHS group (all P <0.05). 2. ROC curve analysis the areas under the curves of DD, PCT, and PLT are 0.670, 0.705, 0.791, respectively, the sensitivity is 40.48%, 100%, 73.81%, and the specificity is 96.43%, 32.14%, 78.57%, respectively. Using the combined analysis of the three series tests, the area under the curve was 0.838, the sensitivity was 71.43%, and the specificity was 85.71%. ConclusionsEHS patients have higher DD, PCT, APACH, but PLT, CRP, Na, and blood sugar are lower. At the same time, the significant decrease of PLT and the increase of PCT and DD may be early sensitive indicators of HS. The combined detection of the three can be used as a reference basis for early diagnosis of HS and critical illness.
