摘要
目的寻求无创性评估肺血管发育的新指标。方法超声心动图采集肺静脉血流频谱,测量Si+Di,SF,Tc等参数;与术后情况进行相关分析。结果Tc与ICU监护时间,呼吸机维持时间,正性肌力药物剂量相关性最高,Si+Di与术后情况相关性较好,SF与术后情况轻微相关。结论Tc是无创性评估肺血管发育及肺血流情况的良好指标,能为外科手术方案的选择提供有效依据。
Objective To investigate a new noninvasive method in estimating development of pulmonary vessels. Methods Parameters of Si＋Di, SF and Tc in pulmonary venous flow pattern were collected by echocardiography. The correlation between parameters of pulmonary venous flow and postoperative outcome was analyzed. Results The time of stay in ICU, duration of mechanical ventilation, dose of inotropic drugs were the best correlated with Tc. Si＋Di was relatively well and SF was mildly correlated with postoperative outcome. Conclusion Tc is a valuable indicator for noninvasive evaluating the development status of pulmonary vessels, which is very helpful in surgical planning.
