1, 2 We review here, the lesser studied and fast evolving use of TEE in patients undergoing non-cardiac surgery, concentrating on obtaining five basic views which can be rapidly reviewed to provide valuable information requisite for non cardiac surgery. TEE is a perioperative diagnostic tool of proven efficacy which can influence surgical and anaesthetic management in patients undergoing cardiac surgery. In intubated patients under general anaesthesia, TEE probe is introduced inside the oesophageal orifice under direct laryngoscopy and is less traumatic than when performed in awake patients. 2009 82(978):509–513.Trans esophageal echocardiography (TEE) is a semi invasive, real time, cardiac imaging modality which has come of age.

There are variations in IVC practice between departments and with international recommended guidelines.Ĭomputerised tomography Intravenous contrast Radiation therapists’ practice Radiation therapy treatment planning scan Target volume delineation. IVC is used extensively in Irish RT departments. IVC training varied in duration and number of supervised procedures required to fulfill competencies. Variations from recommended guidelines were found in disease sites where IVC was routinely used and in the assessment of renal functioning prior to contrast administration. RTTs cannulated patients in 67% ( n = 6/9) of the departments and administration contrast in all departments. All responding departments reported using IVC. ![]() The survey contained open, closed and Likert scale questions that investigated IVC practices in each department.ħ5% ( n = 9/12) of Irish departments responded. This was distributed to all RT departments in Ireland. Radiation Therapists (RTT) IVC training will also be investigated.Īn anonymised online survey was designed based on previously-reported literature. The study aims to examine the patterns of practice in relation to the use of IVC in RT planning scans in Ireland and to determine the level of compliance with international guidelines. ![]() ![]() ![]() Despite this known benefit, there are no guidelines for when and how to use IVC in RT planning scans in Ireland. Intravenous contrast (IVC) use during CT planning can enhance soft tissue contrast optimising Target Volume (TV) and Organ at Risk visualisation and delineation. While Computerised Tomography (CT) remains the gold standard in radiation therapy (RT) planning, inferior soft tissue definition remains a challenge.
