ABSTRACT

Objective:

To explore the early clinical features and the prognostic factors of children with septic shock in PICU.

Methods:

A retrospective analysis was conducted at PICU of the Children′s Hospital, Capital Institute of Pediatrics from January 2016 to November 2018, totally 56 children diagnosed as septic shock were enrolled in the study.According to the prognosis of 28 days, the patients were divided into death group and survival group; according to the lowest pediatric critical score (PCIS) within 24 hours after admission to PICU, the children were divided into non-critical group (>80 points), critical group (70-80 points) and extremely critical group (<70 points). The clinical characteristics of early stage in each group were analyzed and compared.

Results:

Of the 56 children with septic shock, 32 were males and 24 were females, and the mean age was 12.0(1.0, 180.0) months.The overall mortality rate was 37.5%(21/56). The mortality of non-critical group, critical group and extremely critical group were 12.5%(2/16), 16.7%(1/6) and 52.9%(18/34), respectively.There were no statistically significant differences between survival group and death group in gender and age, PICU stay time, heart rate, mean arterial pressure at 1 hour and 24 hours, ventilator using and the duration of mechanical ventilation(all P>0.05). The vasoactive-inotropic score(VIS) at 6 hours and 24 hours of death group were significantly higher than those in survival group[19.0(5.0-29.5) vs.5.0(0.0-10.0), 22.5(3.5-43.8) vs.5.3(0.0-13.5)]. The scores of PCIS in death group were less than that in survival group(57.3±10.7 vs.72.8±12.0)( t=4.85, P<0.001). The lactate level in survival group before resuscitation was statistically lower than that in death group[1.8(1.3-2.8) mmol/L vs.4.5(2.4-8.4)mmol/L]( Z<-3.70, P<0.05). At 1 hour, 6 hours and 24 hours after treatment, fluid resuscitation volume in death group were markedly higher than that in survival group[1 hour (41.8±5.8)ml/kg vs.(38.5±5.3)ml/kg, t=-2.22, P<0.05; 6 hours (69.5±4.4)ml/kg vs.(59.9±3.5)ml/kg, t=-8.96, P<0.05; 24 hours (122.3±19.6)ml/kg vs.(111.7±16.2)ml/kg, t=-2.20, P<0.05]. Multiple sample comparisons found significant differences between the non-critical group[(60.0±3.5) ml/kg] and the extremely critical group[(65.3±6.0) ml/kg, P<0.05], and pairwise comparison of fliud intake within 1 h and 24 h showed no statistically differences( P>0.05). In the univariate analysis, variables significantly associated with death in septic shock were lactic acid before resuscitation and the 24 h lactate clearance rate, VIS 6 h, VIS 24 h, procalcitonin, ejection fraction, PCIS, 6 h-fluid resuscitation volume and multiple organ dysfunction (MODS). The Logistic regression showed that 6 h-fluid resuscitation volume, PCIS, lactic acid and MODS were independent risk factors.ROC curve analysis showed the AUCs of 6 h-fluid resuscitation volume, PCIS, early lactic acid and MODS for predicting death of septic shock children were 0.947, 0.835, 0.797 and 0.761, respectively.

Conclusion:

The mortality of septic shock is high, and decreased PCIS, elected serum lactic acid level and early fluid resuscitation, and MODS are risk factors associated with the death of septic shock.
