Официальное название

Efficacy of Subclavian Vein/Artery Diameter Index in Predicting the Incidence of the Spinal-Induced Hypotension in Geriatric Patients: A Prospective, Observational Study.

Обзор

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.

Подробное описание

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.

Вмешательства

  • Диагностический тест Assessment of the SCV & SCA
    The right SCV was measured using a linear array probe, placed in the sagittal plane at the deltopectoral triangle (beneath the proximal part of the middle of the clavicle and the area below the clavicle). In M-mode, measurements of SCV internal anteroposterior diameter, which is maximum during expiration (SCVmax) and minimum during inspiration (SCVmin), were taken in one respiratory cycle. Ultrasound scan of the patient's supraclavicular area showing the subclavian artery. The index was calcul
  • Диагностический тест Assessment of the IVC and aorta
    The IVC measurement will be obtained in the M-mode scan using a curvilinear (3.5 to 5 MHz) ultrasound transducer. The transducer was placed longitudinally in the subxiphoid region. The IVC maximum and minimum anterior-posterior diameters were obtained just distal to the IVC-hepatic vein junction. In M-mode, measurements of IVC internal anteroposterior diameter, which is maximum during expiration (IVCmax) and minimum during inspiration. IVCmin), were taken in one respiratory cycle.
