Brief Summary

Fluid management in an obstetric patient is a challenging task for theclinicians as both hypovolemia and volume overload increase morbidity andmortality. Pregnant women with predelivery hypovolemia are at risk ofcardiovascular collapse and the sympathetic blockade may severely decreasevenous return.Transabdominal USG measurements of inferior vena cava (IVC) arenoninvasive and thus are associated with minimal complications.Sonographic measurements of the inferior vena cava which predict hypovolemiaand fluid responsiveness could, as a result, help in prediction and thusprevention of post spinal hypotension which is of immense clinicalsignificance. We are expecting that with the help of IVCcollapsibility index we are able to predict hypotension after spinalanesthesia.We may reduce the occurrence of post spinal hypotension and otherhemodynamic fluctuations. We can guide our fluid administration based upon IVC collapsibilityindex and thus prevent hyper-hydration too.
