Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to evaluate the diagnostic accuracy of electrical cardiometry (EC) for the noninvasive determination of fluid responsiveness in sepsis and agreement of (EC) compared to transthoracic echocardiography (TTE).

Detailed Description

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

Usual investigations \[complete blood count (CBC), C reactive protein (CRP), serum procalcitonin, serum lactate, arterial blood gases (ABG), blood culture, electrocardiogram (ECG) and liver and renal function tests\] will be done.

Once the diagnosis of sepsis is definite and the patient develops hypotension, all patients will undergo simultaneous measurement by (EC) using the ICON\_ device and (TTE).

Electrical cardiometry (EC) measurements: by the ICON\_ hemodynamic monitor (ICON Cardiotronics, Inc., La Jolla, CA 92307; Osyka Medical GmbH, Berlin, and Germany, model C3, Serial no: 1725303). Four sensors of (EC) will be applied (1st: 5 cm above the base of the neck, 2nd: on the base of the neck, 3rd: lower thorax at the level of the xiphoid and 4th: 5 cm below the 3rd electrode at the level of the anterior axillary line). The ICON continuously displays heart rate, stroke volume, and cardiac output.

Transthoracic echocardiography (TTE) measurements: will be performed by using Philips (CX50 - Extreme edition) equipped with echo probe. SV of the left ventricle will be calculated using LVOT diameter (D) just below the aortic valve from parasternal long-axis view and velocity time integral (VTI) measured in left ventricle outflow tract (LVOT) from apical 5 chamber view (by pulsed wave Doppler), respectively. The machine's built-in software uses the formula ''(πD2/4) × VTI × HR'' to calculate CO.

Management of sepsis will be done according to surviving sepsis campaign guidelines in 2016 and its update 2018.

Fluid resuscitation will be 30 mL/kg of intravenous infusion of lactated ringer to be given within the first 3 h (≈5 mL/kg/30 min) guided by fluid responsiveness (fluid responder if SV increases by \> 10% after the fluid challenge). If the patient becomes fluid non-responder, vasopressor infusion (norepinephrine 0.05-0.3µg/kg/min) will start. The end of the study is when mean arterial blood pressure \> 65 mmHg (either by fluid or both fluid and vasopressor).
