Measurement of Inferior Vena Cava Size to Predict Hypotension and Guide Intra-operative Fluid Management

Recruiting

• Conditions: Medical and Surgical,

• Registration Number: CTRI/2023/01/049240
• Lead Sponsor: Sri Devaraj Urs Academy of Higher Education

Brief Summary

Different traditional approaches are followed to reduce hypotension following spinal anaesthesia. However, those convers minimal advantage in some patients.



Latest guideline of the American Society of Echocardiography recommends the

use of IVCCI in assessing volume status. In contrast to current traditional approaches, ultrasonographic assessment of the inferior vena cava collapsibility index (IVCCI) is simple, non-invasive, time-efficient, and easily available as well.



In this context, we aim to evaluate

the correspondence of preoperative IVCCI and the incidence of intraoperative hypotension

following spinal anaesthesia.
