Study on clinical assessment of volume status and correlation to the respiratory variation in inferior vena cava diameter by echocardiography, a non-invasive method of measuring volume status
Journal Title: International Archives of Integrated Medicine - Year 2018, Vol 5, Issue 5
Abstract
Introduction: Giving more fluid causes edema and less gives rise to hypoperfusion causing improper delivery of oxygen and substrate leads to cellular dysfunction and multiorgan dysfunction involving the brain, liver, kidneys, heart, lungs and causing death. Diffusion, filtration, osmosis and adequate reabsorption help in continuous exchange of water and solutes among compartment. Daily water intake from the food and water get equalized with losses in the kidneys as urine, from the gastrointestinal system as feces and evaporation of water through lung and skin. Various hormones like Angiotensin II, Aldosterone ADH, Atrial natriuretic peptide maintain sodium and water balance and hence volume status. To maintain normovolemia there is every need for meticulous evaluation for patient Volume status in each patient for adequate volume replacement. Aim of the study: Correlating the Clinical Assessment of Volume Status to the volume assessment By Echocardiography using Respiratory Variation in Inferior Vena Cava Diameter. Materials and methods: Study population consisted of 200 patient of medicine department both inpatient and outpatient of Chengalpattu Medical college. The patient was examined clinically, history suggestive of volume depletion and history suggestive of volume overload were noted, signs and symptoms of both hypovolemia and hypervolemia were noted. Echocardiography was used as a noninvasive method of measuring volume status. Results: Correlation of assessment of volume status by the clinical method and IVC method as low, normal and high was represented. Correlation – 0.797, P value < 0.001 which tell that there was a statistically significant correlation between your two variables. That means, increases or decreases in IVC do significantly relate to increase or decrease. Conclusion: The use of echocardiography as a non-invasive mode of volume assessment is helpful to empower the clinical assessment methods and hence improves diagnostic accuracy.
