Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cardiac output (CO) and Stroke Volume (SV) can be used as markers for global cardiovascular functions and can assess fluid responsiveness to ensure adequate tissue perfusion which is one of the essential concerns of anesthestists and intensivists The gold standard is the thermodilution procedure by pulmonary artery catheter (PAC), yet, cannot be considered as a routine owing to potential difficulty and virtual complications The development of safe, simple, minimally invasive or non-invasive techniques which estimate CO, SV and systemic vascular resistance (SVR) without invasive intravascular catheterization or dye injection is important for clinical decision-making and research in anesthesia and critical care medicine Echocardiography in comparison with other Doppler modalities is a potent diagnostic mean that has the superiority above the traditional PAC for both diagnostic precision and rapidity However, the use of echocardiography needs good training and relatively expensive. Another ultrasound based device is Esophageal Doppler(ED) which looks more suitable for prolonged hemodynamic monitoring. This technique is minimally invasive which calculates the blood flow velocity in descending aorta and can determine SV and CO with sound trustworthiness. Such technique needs less training than standard echocardiography or PAC Thoracic Electric Bioimpedance (TEB) is a noninvasive monitoring which correlates differences in thoracic electrical conductivity to thoracic aortic blood volume and flow. It is a simple method for detection of SV, CO, contractility, SVR, and thoracic fluid content (TFC) for continuous monitoring. The results of previous studies comparing impedance cardiography with thermo dilution and other methods like transoesophageal echocardiography (TEE) have been largely inconclusive which may referred to higher thorax fluid content and consequently higher conductivity after surgical procedure To overcome these problems, upgraded computer equipment and advanced algorithms are used in the newer model; electrical cardiometry (EC), that interprets the maximum changes in TEB and can calculate CO accurately in adults and neonates Although other study compared between two devices in patients undergoing major abdominal and pelvic surgeries , but the sample size was small rather than our study , also it included laparoscopic surgeries which affect hemodynamics (blood pressure , heart rate and other cardiac parameters ) in such points . In addition investigators used the old version of thoracic bio-impedance (NICOM) which is different from our device as we will us (ICON) , Like another study comparing between two devices used also the old version of thoracic bio-impedance and didn't specify the type of surgery at which the study was done . There are also other studies comparing the two devices one of them in paediatrics undergoing kasai operation and the second in patients during liver transplantation , these two studies contain two types of patients not included in the present study .
