About

With using suction tube attached TEE probe cover, we will assess its pinpoint suction capacity on image quality and surgical decision making.

Full description

Background: Transesophageal echocardiography (TEE) has become a standard intraoperative diagnosis technique for clinical management of patients during cardiac and non-cardiac surgery. Accurate intraoperative diagnosis by TEE improves as image quality improves. Although we recently reported enhanced image quality using a TEE probe with an attached orogastric tube, its clinical significance is still unknown. Also, we are concerned about potential clinical complications including damage to the upper gastrointestinal tract due to its rough surface. Therefore, we devised a new TEE probe cover equipped with a suction catheter and ultrasound gel containing pad that functions as a cushion for preventing surrounding tissue trauma. Our long-term goal is to improve TEE image quality, which will help surgical decision-making with precise assessment. The study population will be elective cardiac cases and liver transplant cases at Henry Ford Hospital. The objective of this grant is to assess the image quality change with our newly designed TEE probe, and its clinical utility on patient care in different types of procedures.

Aim 1. To assess TEE image quality before and after pin-point suctioning with our newly designed TEE probe. We hypothesize that decreasing stomach air between the TEE probe transducer and tissue wall by pin-point suction with our newly designed TEE probe will reduce ultrasound reflection and lead to better image quality.

Aim 2. To evaluate the clinical utility of our newly designed TEE probe cover. We hypothesize our newly designed TEE probe cover will facilitate decision-making for both anesthesiologists and surgeons and it will not increase the occurrence of TEE probe related trauma.
