spinal anesthesia inducted hypotension
Conditions
Interventions
US group:The maximum (IVCDmax) and minimum (IVCDmin) diameters of the IVC were measured respectively over the same respiratory cycle. The IVCCI was derived from the formula:IVCCI =(IVCDmax -IVCDmin)/I
C group:standard volume management
