Ultrasonographic Assessment of Neck Vessels as Predictors of Spinal Anesthesia Induced Hypotension in Elderly

Post-spinal Hypotension Clinical Trial

Official title: Pre-anesthetic Ultrasonographic Assessment of Neck Vessels as Predictors of Spinal Anesthesia Induced Hypotension in Elderly: a Prospective Observational Study.

Status Completed

Clinical Trial Summary

Spinal anesthesia induces sympathetic blockade and venodilation, thus reducing venous return and the cardiac output. Therefore, assessment of intravascular volume deficit before anesthesia might predict a critical decrease in blood pressure after anesthesia.

Recently, ultrasonographic evaluation of the internal jugular vein (IJV) has been used to reflect intravascular volume status and fluid and as a predictor of hypotension after induction of general anesthesia.

Carotid intima-media thickness (CIMT) has been used to predict atherosclerosis-related events, such as stroke, myocardial infarction, peripheral artery disease, and hypotension after induction of anesthesia with a cut-off value of 0.65 mm of CIMT as a threshold level.

Clinical Trial Description

This study aims to evaluate the ability of preoperative Ultrasonographic assessment of the internal jugular vein (IJV) and Carotid intima-media thickness (CIMT) to predict spinal anesthesia induced hypotension (SAIH).

Participants will be elderly patients (above 60 years), ASA I-II-III, scheduled for elective surgeries under spinal anesthesia. ;
