Abstract :Objectives: Hypotension is a common complication of spinal anesthesia. Imaging of inferior vena cava insert ignore into journalissuearticles values(IVC); and measurement of the IVC-collapsibility index insert ignore into journalissuearticles values(IVC-CI); by ultrasonography insert ignore into journalissuearticles values(USG); has been a widely used non-invasive, easy and reliable method for measurement of the fluid imbalance. In the present study, we aimed to investigate the predictive ability of the maximum IVC diameter insert ignore into journalissuearticles values(dIVCmax); and IVC-CI for hypotension after spinal anesthesia. Methods: The study was designed as prospective and observational. One hundred thirty-two patients aged 18-75 years with ASA I-II underwent inguinal hernia surgery with spinal anesthesia and recruited to the study. Maximum and minimum insert ignore into journalissuearticles values(dIVCmin); IVC diameters were measured. IVC-CI insert ignore into journalissuearticles values(%); was quantified according to the formula of [insert ignore into journalissuearticles values(dIVCmax - dIVCmin);/dIVKmax] × 100%. Results: The patients were grouped as hypotensive and non-hypotensive. In fifty-seven patients of 120 cases insert ignore into journalissuearticles values(47.5%);, hypotension has emerged following spinal anesthesia. No significant differences in dIVCmax and IVC-CI were recorded between the study groups insert ignore into journalissuearticles values( p > 0.05);. There were significant inverse correlation between age and IVC-CI. Significant positive correlation between the lowest values of the systolic arterial pressure, diastolic arterial pressure, mean arterial pressure and IVC-CI and significant positive correlation between dIVCmax and diastolic blood pressure, maximum and minimum values of the mean arterial pressure. Conclusions: We found that dIVCmax and IVC-CI values measured before spinal anesthesia were not sufficient parameters enough to predict hypotension after spinal anesthesia. Further studies investigating the IVC measurements under spinal anesthesia together with dynamic hemodynamic monitorization modalities are needed.
