To evaluate the role of echocardiography in reducing shock reversal time in pediatric septic shock.
A prospective study conducted in the pediatric intensive care unit of a tertiary care teaching hospital from September 2013 to May 2016. Ninety septic shock patients were randomized in a 1:1 ratio for comparing the serial echocardiography-guided therapy in the study group with the standard therapy in the control group regarding clinical course, timely treatment, and outcomes.
Shock reversal was significantly higher in the study group (89% vs. 67%), with significantly reduced shock reversal time (3.3 vs. 4.5 days). Pediatric intensive care unit stay in the study group was significantly shorter (8±3 vs. 14±10 days). Mortality due to unresolved shock was significantly lower in the study group. Fluid overload was significantly lower in the study group (11% vs. 44%). In the study group, inotropes were used more frequently (89% vs. 67%) and initiated earlier (12[0.5-24] vs. 24[6-72]h) with lower maximum vasopressor inotrope score (120[30-325] vs. 170[80-395]), revealing predominant use of milrinone (62% vs. 22%).
Serial echocardiography provided crucial data for early recognition of septic myocardial dysfunction and hypovolemia that was not apparent on clinical assessment, allowing a timely management and resulting in shock reversal time reduction among children with septic shock.
评估超声心动图在缩短儿科感染性休克患者休克逆转时间中的作用。
这是一项前瞻性研究,于 2013 年 9 月至 2016 年 5 月在一家三级教学医院的儿科重症监护病房进行。90 例感染性休克患者按 1:1 的比例随机分为研究组和对照组,比较两组在临床过程、及时治疗和结局方面的连续超声心动图引导治疗与标准治疗。
研究组休克逆转率显著高于对照组(89% vs. 67%),休克逆转时间显著缩短(3.3 天 vs. 4.5 天)。研究组儿科重症监护病房住院时间明显缩短(8±3 天 vs. 14±10 天)。因休克未得到解决而导致的死亡率在研究组显著降低。液体超负荷在研究组显著降低(11% vs. 44%)。在研究组,正性肌力药物的使用更为频繁(89% vs. 67%),且更早开始使用(12[0.5-24]小时 vs. 24[6-72]小时),最大血管加压素正性肌力评分较低(120[30-325]比 170[80-395]),米力农的使用率较高(62% vs. 22%)。
连续超声心动图为早期识别临床评估不明显的感染性心肌功能障碍和低血容量提供了关键数据,使儿童感染性休克患者能够及时进行管理,从而缩短休克逆转时间。
