Abstract:
Objective:To analyse the ultrasound changes of heart systolic function after trauma in children and their relationship with the degree of trauma.Methods:All children with trauma admitted to the PICU at Shengjing Hospital of China Medical University from January 2022 to December 2022 were prospectively selected as the research subjects.According to the injury severe score (ISS) at admission,they were divided into mild-moderate trauma group(ISS≤25) and severe trauma group (ISS>25).Transthoracic echocardiography was performed within 72 hours of admission (acute phase) and upon transfer from the PICU or discharg (recovery phase).Clinical information,mainly including age,gender,and cause of trauma,was collected for all children.The ejection fraction (EF),motion amplitude (displacement),and difference rate of each segment of the left ventricle were compared between mild-moderate trauma group and severe trauma group in acute phase and recovery phase.Results:A total of 40 children were included,including 27 males and 13 females with a median age of 5 (2,8) years old.There were 20 children in the mild-moderate trauma group and 20 in the severe trauma group.The EF of each segment,displacement of the base of the ventricular septum,and displacement of each segment of the posterior wall in the mild-moderate trauma group in the acute phase were significantly lower than those in the recovery phase ( P<0.05).The EF of each segment,displacement of the ventricular septum of each segment,displacement of the middle and apex segment of the posterior wall in the severe trauma group in the acute phase were significantly lower than those in the recovery phase ( P<0.05).The EF values ??of the base,middle segment and short axis in the severe trauma group in the acute phase were significantly lower than those in the mild-moderate trauma group ( P<0.05).The EF of the apex and displacement of the base segment of the posterior wall were lower than those in the mild-moderate trauma group,but the differences were not statistically significant ( P > 0.05).There was no statistically significant difference in the EF values ??of each segment between the severe trauma group and the mild-moderate trauma group in the recovery phase ( P>0.05).Comparison of the difference rates between the acute phase and the recovery phase showed that the EF difference rates ( P<0.05) and displacement difference rates ( P>0.05) of each segment in the severe trauma group were larger than those in the mild-moderate trauma group.In the recovery phase,the EF values ??of the apex,middle segment,and base of the mild-moderate and severe trauma groups decreased in turn ( P>0.05),and the displacement of the apex,middle segment,and base of the ventricular septum decreased in turn ( P<0.05).The EF difference rate of the apex and the displacement difference rate of the apex of the posterior wall in the mild-moderate trauma group were higher than those of the corresponding middle and base segment,but the differences were not statistically significant ( P>0.05). Conclusion:The heart systolic function in children decreases after trauma,and the changes are segmental.The decrease in heart systolic function is more obvious in children with severe trauma.
