简要总结
The hypothesis of the study will be that the subclavian vein/subclavian artery diameter (SCVD/SCAD) index will be a good predictor of spinal-induced hypotension in geriatric patients.
详细描述
Ultrasonography (USG)-guided measurement of inferior vena cava (IVC) diameters and IVC collapsibility index (IVCCI) are reliable indicators of intravascular volume status and of clinical response to volume resuscitation.
The cava/aorta index had previously shown good ability in assessing volume status and predicting post-spinal hypotension.
The subclavian vein (SCV) is advantageous for measurement as it's supported by the clavicle, preventing deformation or compression. It is also not affected by pregnancy, obesity, or abdominal pain, and its anatomical position remains fixed.
The hypothesis of the study will be that the subclavian vein/subclavian artery diameter (SCVD/SCAD) index will be a good predictor of spinal-induced hypotension in geriatric patients.
