Role of DVET in severe neonatal sepsis in an era of high antibiotic resistance: a retrospective observational study.

AIM: Sepsis is a significant cause of mortality and morbidity in the NICU despite the potent armamentarium of antibiotics. Recently, there has been a considerable increase in antimicrobial resistance even to high-end 3rd line antibiotics. Thus, there is a need to look into adjunctive therapies. This study aims to study the role of double volume exchange transfusion (DVET) in reducing mortality due to severe sepsis.

METHODS

All neonates with severe sepsis admitted in NICU from January 2017 to September 2019 were included in the study. Seven neonates who met inclusion criteria and received DVET were compared to 21 gestation and severity matched controls, who received standard therapy (ST) alone. The primary outcome studied was mortality before discharge in both the groups. Other results analyzed were the incidence of persistent thrombocytopenia and refractory shock.

RESULTS

There was a significant reduction in mortality in the intervention group (57% vs. 71% (p = .004). There was also a significant reduction both in the incidence of refractory shock (71% vs. 75%; p = .01) and persistent thrombocytopenia (86% vs. 65%; p = .03) in the DVET group. No significant adverse effects occurred following DVET.

CONCLUSIONS

In neonates with severe sepsis, DVET may be a useful adjunct therapy. It may reduce mortality and decreased the incidence of refractory shock and thrombocytopenia. DVET is a safe procedure in severely sick and septic neonates.
