Abstract
Background Hand, foot, and mouth disease (HFMD) is an acute infectious disease caused by human enterovirus 71 (EV71), coxsackievirus, or echovirus, which are particularly common in preschool children. Severe HFMD is prone to cause pulmonary edema, and successively progresses to respiratory and circulatory failure; thus hemodynamic monitoring and fluid management are important in the treatment process. Methods We reviewed young patients with severe HFMD, caused by EV71, and who had been successfully treated in our department. A total of 20 patients met the inclusion criteria. Eight cases were monitored by the pulse indicator continuous cardiac output (PiCCO) technique, and fluid management was administered according to its parameters. With regard to the treatment with PiCCO monitoring, patients were divided into two groups: the PiCCO group (8 patients) and the control group (12 patients). The groups were then compared comprehensively to evaluate whether PiCCO monitoring could improve the clinical outcomes. Results After analysis, the findings were that although PiCCO failed to shorten the length of ICU stay, reduce the days of vasoactive drug usage, or reduce the number of cases which needed mechanical ventilation, it did reduce the incidence of fluid overload (p=0.085) and shortened the days of mechanical ventilation (p=0.028). After effective treatment, PiCCO monitoring showed that the cardiac index (CI) increased gradually(p<0.0001), whereas the pulse (P, p<0.0001), the extra vascular lung water index (EVLWI, p<0.0001), the global end diastolic volume index (GEDVI, p=0.0043), and the systemic vascular resistance index (SVRI, p<0.0001) all decreased gradually. Conclusion Our study discovered that PiCCO hemodynamic monitoring in young children with severe HFMD has potential clinical benefits, such as reducing fluid overload and duration of mechanical ventilation. However, whether it can ameliorate the severity of the disease, reduce mortality, or prevent multiple organ dysfunction remain to be further investigated.
