Summary

Fluid are used to increase cardiac output (CO) and blood pressure in patients admitted to the intensive care unit (ICU) .Fluid is an important line of therapy that needed in shocked patient, hypovolemic and following surgery to correct the volume state and avoid acute kidney injury. However, excess fluid administration may be harmful leading itself to increase rates of acute kidney injury (AKI), prolonged days of mechanical ventilation and death . Excess fluid administration may increase right and left atrial pressure leading to congestion and edema.

Interventions

OTHER

doppler US of portal vein, hepatic veins, intrarenal veins

Hepatic Vein Doppler : To obtain the HV PW, a phased array transducer is used with cardiac pre-sets. ECG leads are placed to assist in the interpretation of HVD in sinus rhythm as well as atrial fibrillation. The middle hepatic vein is identified from mid-subcostal or lateral views during the end-expiratory phase of the patients respiratory cycle. Portal vein Doppler: From a lateral costal or subcostal window, the portal vein is identified in the coronal plane using a phased-array transducer. The PV were considered abnormal if the pulsatilty index was greater than 30%. The portal pulsatility index was defined as: (VMax - VMin/VMax) \* 100%. Here, VMax is the maximal velocity and VMin is the minimal velocity during the cardiac cycle. Intra-renal venous Doppler: From lateral costal window, the kidney is located in the coronal plane and a color flow box placed over the distal renal calyceal junction to cortex.
