Tricuapid Annular Plane Sistolic Excursion Before General Anesthesia Can Predict Hypotension After Induction

Bursa City Hospital7 enrolled

Overview

the investigators purpose is to predict hypotensive condition that can develop after general anesthesia induction by measuring the Tricuspid Annular Plane Systolic Movement (TAPSE), which is an echocardiographic parameter.

Intraoperative hypotension development might increase myocardial damage, acute kidney damage, and septic complications, and have an effect on mortality increase. For this reason, prevention of an unwanted hypotensive event has an important role in reducing mortality and morbidity. The prediction of the risk of hypotension is generally based on the evaluation of the comorbid status and volume status of patients .It is already known that right ventricular systolic dysfunction has prognostic value in various pathological cases. It is quite difficult to evaluate the RV function with echocardiography because of the complex geometry of RV. Although RV function has been evaluated only visually for many years, guidelines have been published as a result of recent studies by the American Society of Echocardiography. In this respect, abnormal RV function should be suspected when one of the criteria of S '\<10 cm /s, TAPSE \<16 mm, RVFAC \<35%, or R-MPI (Tissue Doppler)\> 0.55. Normal and abnormal function is distinguished more reliably when combining more than one RV function measures. TAPSE is a parameter with which the apex-basal shortening can be easily measured, providing specific data on global RV function. It depends less on optimal image quality than other RV function measurements, and is an easy-to-measure criterion. Low TAPSE is not very common; however, it was measured in people with no heart disease due to diagnostic misclassification and excessive ends of the normal spectrum. the investigators think that despite the lack of cardiac disease, cardiac reserve functions of each patient may have limits in terms of development of hypotension in general anesthesia induction. The investigators considered that TAPSE, which decreased within normal limits in patients without cardiac disease, could predict hypotension development in general anesthesia induction, and planned study for this purpose.

tricuspid anular plane systolic excursion(TAPSE)

The investigators purpose is to predict hypotensive condition that can develop after general anesthesia induction by measuring the Tricuspid Annular Plane Systolic Movement (TAPSE), which is an echocardiographic parameter.

Time frame: TAPSE will be measured with Transthoracic Echocardiography about 30 minutes before the induction in the preoperative period.
