Spinal Anesthesia Hypotension
Conditions
Brief summary
we aimed to evaluate the change in femoral artery pulsatility index as a predictor to post-spinal anesthesia hypotension
Detailed description
After spinal anesthesia, hypotension is a common effect that occurs in between 15 and 30% of patients therefore it is essential to prevent such effect. number of variables were utilized for estimating post spinal hypotension, such as assessing heart rate variability, perfusion index, inferior vena cava collapsibility index; however, the majority of these indices needs advanced equipment. investigator of current research decided to study the role of ultrasound derived index namely pulsatility index to predict post spinal anesthesia hypotension.
