Official title
Arterial Stiffness as a Predictor of Acute Kidney Injury in Patients With Sepsis
Overview
To investigate whether arterial stiffness, as defined by measuring Pulse Wave Velocity, could be identified as an independent risk factor for development of acute kidney injury in sepsis. To compare between the Pulse Wave Velocity and shear wave ultrasound elastography (SWE) as a different methods of evaluation of arterial stiffness in prediction of acute kidney injury in sepsis.
Detailed description
Demographic and historical data: the patient age, sex, history of hypertension, diabetes ,peripheral vascular disease , IHD, source of sepsis and indication of mechanical ventilation if indicated.
Clinical examination data: pulse, blood pressure, respiratory rate, temperature and thorough chest, cardiac and neurological examination data will be obtained.
Volume state of the patient: CVP measurement, input and output fluid chart. Investigation : CBC( Neutrophil count, Neutrophil/lymphocyte ratio), Blood urea and serum creatinine ,serum electrolytes, serum lactate,serum albumin,CRP ,coagualtion profile and lipid profile. sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHE II) score, and complete sepsis workup to identify the possible sources of sepsis.
12 lead ECG and Echocardiographic data that include: Left and right atrial dimensions. The left ventricular ejection fraction will be assessed by the Simpson method, left ventricular diastolic function will be assessed by measuring velocities of the mitral E and A waves and of the e' wave of the external mitral annulus and by calculating the E/e' ratio. Right ventricle dimension and dysfunction will be evaluated by TAPSE and pulmonary artery acceleration time. Pulmonary artery pressure will be measured from Tricuspid flow if possible.
Pulse Wave Velocity (PWV), a measurement of arterial stiffness, will be assessed at the systemic region (carotid-femoral PWV), which is the gold standard method. In the first 24 hours of admission.
The two-dimensional SWE technique will be used in our study , an imaging method will be obtained by simultaneously applying multiple ARFI waves into the tissue and measuring the resulting shear waves .It will be assessed in the first 24 hours of admission.
RRI will be measured at the time of admission. All measurements will be performed by the same examiner and repeated by an independent blinded operator. Using pulse-wave Doppler, an interlobar or arcuate artery will be selected. RRI will be calculated as the equation "(PSV-EDV)/PSV". The means of three distinct RRI calculations will be recorded.
