| 目的 以二维斑点追踪成像(2D-STI)观察脓毒症患儿左心室收缩功能变化。方法 回顾性选择29例脓毒症患儿,根据相关诊断标准分为严重脓毒症组(n=10)与非严重脓毒症组(n=19),另以21名健康儿童为对照组;比较3组间及两两组间常规超声心动图参数及2D-STI参数。结果 3组间左心房内径(LAD)、左心室舒张末期内径(LVEDD)及右心房内径(RAD)差异均有统计学意义(P均＜0.05),而右心室舒张末期内径(RVEDD)及左心室射血分数(LVEF)差异均无统计学意义(P均＞0.05)。3组间左心室整体纵向应变(LVGLS)及基底段前壁(BA)、基底段前侧壁(BAL)、基底段后侧壁(BIL)、中间段前壁(MA)、中间段前侧壁(MAL)、中间段后侧壁(MIL)、心尖段前壁(APA)、心尖段侧壁(APL)、心尖段下壁(API)、心尖帽(APEX)节段纵向应变(LS)差异均有统计学意义(P均＜0.05);其中,两两组间比较LVGLS差异均有统计学意义(P均＜0.05),严重脓毒症组与对照组BAL、BIL、MA、MAL、MIL、APA、APL、API及APEX节段LS,非严重脓毒症组与对照组BAL及MAL节段LS,严重脓毒症组与非严重脓毒症组BA、MA、APL、API及APEX节段LS差异均有统计学意义(P均＜0.05)。结论 脓毒症患儿LVEF尚在正常范围时左心室2D-STI参数已发生变化,且部分参数与病情严重程度有关。 |

| Objective To observe the changes of left ventricular systolic function in children with sepsis by two-dimensional speckle tracking imaging (2D-STI). Methods A total of 29 children with sepsis were retrospectively enrolled and divided into severe sepsis group (n=10) and non-severe sepsis group (n=19) according to relevant diagnostic criteria, while 21 healthy children were taken as controls (control group). Conventional echocardiographic parameters and 2D-STI parameters were compared among 3 groups and between each 2 groups. Results Significant differences of left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD) and right atrial diameter (RAD) were found among 3 groups (all P＜0.05), while no significant difference of right ventricular end-diastolic diameter (RVEDD) nor left ventricular ejection fraction (LVEF) was noticed (both P＞0.05). Meanwhile, significant differences of left ventricular global longitudinal strain (LVGLS) and basal anterior (BA), basal anterolateral (BAL), basal inferolateral (BIL), mid-anterior (MA), mid-anterolateral (MAL), mid-inferolateral (MIL), apical anterior (APA), apical lateral (APL), apical inferior (API) and apex cap (APEX) segment longitudinal strain (LS) were found among 3 groups (all P＜0.05), also of LVGLS between each 2 groups, of LS in BAL, BIL, MA, MAL, MIL, APA, APL, API and APEX segments between severe sepsis group and control group, of LS in BAL and MAL segments between non-severe sepsis group and control group, and of LS in BA, MA, APL, API and APEX segments between severe sepsis group and non-severe sepsis group (all P＜0.05). Conclusion Left ventricular 2D-STI parameters in children with sepsis changed when LVEF was still in normal range, and some parameters were related to the severity of disease. |
