The relationship between collapsibility index of inferior vena cava and hypotension after spinal anesthesia

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