ABSTRACT
Objective To analyze the prognosis of pediatric burns and its influencing factors. Methods Clinical data of 1 737 children with burns from January 2013 to December 2017 in the First Affiliated Hospital of Anhui Medical University was analyzed by retrospective method. The demographic, clinical features, and related factors affecting prognosis . Results Log-binominal regression model showed that the care rate was higher in children aged 1- and 3- compared with children aged 7-12 (all P<0.05); Boiling water burns had a higher care rate than electric shock and flame burns (including chemical burn) (all P<0.05); Moderate and severe burns had a higher care rate than heavy severe burns (all P<0.05); The unhealed rate of pediatric burns in summer was higher than burned in winter (RR=0.861,95% CI:0.690-1.074); Children without complications had a higher care rate (P<0.05); Children lived in rural areas have a higher unhealed rate than lived in urban areas (RR=0.713，95% CI:0.618-0.824). Conclusions The care rate of pediatric burns was 51.1%. Major influencing factors included children aged 7-12, burned by electric and flame (including chemical burns), burned severe extraordinarily, burned in summer, and with complications, lived in rural.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influence of the changes in the levels of calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY) on cardiac function of severe burn patients during shock stage.</p><p><b>METHODS</b>Sixty severe burn patients with total burn surface area larger than 30% were enrolled as experiment group (E group) , and they received fluid resuscitation and debridement during shock stage. Sixty healthy volunteers were enrolled as control group (C group). The changes in the plasma level of CGRP, NPY and cTnT in E and C groups were observed at 1, 3, 6, 12, 24, 48 post-burn hours (PBH). The correlation among the CGRP, NPY and cTnT in the C group were analyzed.</p><p><b>RESULTS</b>At 3 PBH, the plasma level of CGRP in E group (28 +/- 6) ng/L was lower than that in C group (55 +/- 7) ng/L , and it reached the lowest level at 12 PBH (15 +/- 4)ng/L . It was still lower than that in C group at 48 PBH (P < 0.05). The levels of NPY and cTnT in E group were significantly increased at 1PBH [(136 +/- 20) ng/L, (0.41 +/- 0.08) microg/L] compared with that in C group[ (86 +/- 13) ng/L, (0.16 +/- 0.06) microg/L], peaking at 12PBH [(189 +/- 31) ng/L, (1.78 +/- 0. 47) microg/L], and remaining higher than those in C group at 48PBH. There exhibited obvious negative correlation between the changes in the level of CGRP and cTnT ( r = -0.76, P < 0.01), while obvious positive correlation was found between the changes in level of NPY and cTnT ( r = 0.79, P < 0.01).</p><p><b>CONCLUSION</b>The decrease in CGRP level and the increase in NPY level might play important roles in myocardial injury during shock stage of severe burn patients.</p>
