Therapy of septic shock in children is a key issue of intensive care.
OBJECTIVE
To assess an effectiveness of extracorporeal hemocorrection (EH) in therapy of septic shock in children.
MATERIAL AND METHODS
A multiple-center observational uncontrolled study included 62 children aged 5 (2-13) years. Depending on timing and technique of EH, all patients were divided into 3 groups: group I — EH only for signs of acute kidney injury (AKI); group II — EH before AKI or for renal damage grade 1. In both these groups, only continuous veno-venous hemodiafiltration (CVVHDF) was used. In group III, EH was started immediately after diagnosis of septic shock, CVVHDF was combined with polymyxin B hemoperfusion. Cardiac index (CI), endotoxin activity assay (EAA), neutrophil phagocytic activity, vasoactive Inotrope Score (VIS), duration of mechanical ventilation and incidence of acute kidney injury were evaluated to assess effectiveness of therapy.
RESULTS
Significant decrease of VIS compared to baseline value was noted in groups II (by 18.75%) and III (by 43.74%). In group III, we found significant increase of CI (from 3.1 to 4.0L/min/m2; p<0.05). In the same group, EAA reduction from 0.69 to 0.52 was detected a day after surgery (p<0.01). Moreover, we observed increase of phagocytic activity of neutrophils (from 0.56 to 0.6; p<0.05). Among survivors in all groups, restoration of kidney function was observed in 89.9% of cases. Incidence of terminal AKI followed by hemodialysis was 11.1%. In-hospital mortality was minimal in the third group.
CONCLUSION
Early EH (CVVHDF combined with polymyxin B hemoperfusion) reduces ICU stay and improves the outcomes in children with septic shock.
