Primary outcomePrimary: Image Quality Assessment Method#1: Difference in Likert Scale Before and After Suctioning — 79; 62; 0 image sets
Summary
Image quality of intraoperative transesophageal echocardiography (TEE) tends to get worse during long hours of operations. An orogastric tube (OGT) is often inserted in the beginning of the case, and left there for intermittent suction as needed, or removed before TEE exam to prevent echoic artifacts. However, if left there, the effect of suction might be limited due to unreliable tip position of the OG tube. If removed, stomach will be distended again. We devised the OG tube attached TEE for practical suction and assessed its effect on image quality intraoperatively.
