ABSTRACT

Objective:

To assess the left ventricular function and hemodynamic status in infantile pneumonia by ultrasonic cardiac output monitor (USCOM).

Methods:

The clinical data of 74 children with infantile pneumonia hospitalized in the Department of Pediatrics of Affiliated Hospital of North Sichuan Medical College from October 2018 to January 2020 were collected in this study, and those cases were divided into the mild pneumonia group (45 cases) and the severe pneumonia group (29 cases). USCOM was employed to measure such data of patients in both groups as heart rate (HR), flow time corrected (FTc), stroke volume variability (SVV), stroke volume index (SVI), cardiac index (CI), inotropy index(INO), and systemic vascular resistance index (SVRI). The specific values of CI and SVRI in all ages were employed to determine the hemodynamic type.According to values of CI, they were grouped into normal, high and low output; according to values of SVRI, they were grouped into normal, high and low resistance.The left ventricular function and hemodynamic status of infants with pneumonia in both groups were compared.

Results:

(1) In the mild pneumonia group, 42.22% of infants (19/45 cases) presented with abnormal hemodynamic status, of which 94.74% were high-output and low-resistance type.In the severe pneumonia group, 79.31%(23/29 cases) of infants presented with abnormal hemodynamic status, of which 86.96%(20/23 cases) were non-high-output and non-low-resistance type.The proportion of different hemodynamic types from high to low in order is as follows low-output and high-resistance (39.13%), high-output and normal-resistance (26.09%), low-output and low-resistance (13.04%), and normal-output and low-resistance (8.70%). (2)Before treatment, HR, SVI, CI, INO and SVRI in the severe pneumonia group and the mild pneumonia group were (153.2±19.3) times/min, (32.0±5.8) mL/m 2, (4.3±1.0) L/(min·m 2), (1.1±0.4) W/m 2, (1 139.0±280.6) d·s·cm -5·m 2 and(140.2±13.2) times/min, (39.2±4.1) mL/m 2, (5.1±0.8) L/(min·m 2), (1.4±0.2) W/m 2, and (904.7±175.8) d·s·cm -5·m 2, respectively.SVI, CI and INO in the severe pneumonia group were lower than those in the mild pneumonia group, which indicated that the difference was statically significant (all P<0.05). HR and SVRI in the severe pneumonia group were higher than those in the mild pneumonia group, which indicated that the difference was statically significant (all P<0.05). There was no significant difference in cardiac preload between both groups before treatment ( P>0.05). HR in the severe pneumonia group after treatment[(137.6±9.3) times/min] were significantly lower than before treatment, while SVI and CI[(36.2±3.4) mL/m 2, (4.7±0.3)L/(min·m 2)] were higher than before treatment, which indicated that the differences were statistically significant (all P<0.05).

Conclusions:

The USCOM provided a rapid approach for the dynamic measurement of left ventricular function and hemodynamic status.As per the findings with USCOM, more infants with mild pneumonia presented with hemodynamic abnormalities, and most of them were high-output and low-resistance types.The majority of infants with severe pneumonia presented with different types of hemodynamic abnormalities, and most of them were non-high-output and non-low-resistance types, which can return to normal after treatment.
