PURPOSE
There has been reluctance to use intraoperative transesophageal echocardiography (TEE) in small infants. We assessed the utility and safety of a new miniaturized multiplane micro-TEE probe in small infants undergoing cardiac operations.
DESCRIPTION
Hemodynamic and ventilation variables were prospectively recorded before and after micro-TEE insertion and removal in infants weighing 5 kg or less undergoing cardiac operations.
EVALUATION
The study included 42 patients with a mean weight of 3.6 +/- 0.9 kg (range, 1.7 to 5 kg). All probe insertions were successful. There were no complications or clinically significant changes in hemodynamic or ventilation variables. Information provided by TEE resulted in surgical revision in 6 of the 42 patients.
CONCLUSIONS
The micro-TEE provides high quality, useful diagnostic images without hemodynamic or ventilation compromise in small infants undergoing cardiac operations. This advance is important with the growing trend towards complete repair of complex structural heart disease in small infants.
目的
对于小型婴儿，人们一直不愿意使用术中经食管超声心动图（TEE）。我们评估了一种新型微型多平面微 TEE 探头在接受心脏手术的小型婴儿中的使用效果和安全性。
描述
在体重为 5 公斤或以下的婴儿进行心脏手术时，前瞻性地记录了微 TEE 插入和取出前后的血流动力学和通气变量。
评估
该研究包括 42 名平均体重为 3.6±0.9 公斤（范围 1.7 至 5 公斤）的患者。所有探头插入均成功。无并发症或血流动力学或通气变量出现临床显著变化。TEE 提供的信息导致 42 名患者中的 6 名进行了手术修正。
结论
微型 TEE 可在接受心脏手术的小型婴儿中提供高质量、有用的诊断图像，而不会对血流动力学或通气造成影响。随着在小型婴儿中进行复杂结构性心脏病完全修复的趋势不断增长，这一进展非常重要。
