A New Study For Assessment Of Role Of Change In Diameter Of A Large Vein In Abdomen And Peak Velocity Of Blood In A Major Artery In Neck With Respiration,Interpreted With Ultrasound, In Prediction Of Post Spinal Anaesthesia Hypotension In Spontaneously Breathing Patients

Completed

• Conditions: Malignant neoplasm of long bones of lower limb, (2) ICD-10 Condition: N00-N99||Diseases of the genitourinary system,

• Registration Number: CTRI/2018/03/012485
• Lead Sponsor: All India Institute of Medical Sciences New Delhi

Brief Summary

Hypotension is a common side effect of spinal anesthesia. There is no gold standard test to predict poat spinal hypotension.Isg guided assessment of  IVC Collapsibility Index (IVCCI) and doppler guided measurement of variations of Carotid artery peak systolic  velocity (CAPV) are two widely used predictors of fluid responsivenss. Fluid responsivenss and hypotension are closely related. We therefore want to do a pilot study to assess if there is any correlation of of IVCCI and CAPV with post spinal hypotension. As there’s no available to best of our knowledge, we will do a pilot study.
