Exploring the predictive value of carotid Doppler ultrasound and clinical features for spinal anesthesia-induced hypotension: a prospective observational study
Authors' conclusion
Combining carotid Doppler ultrasound measurements and clinical variables can predict the occurrence of SAIH.
Study context
- Population
- Adults scheduled for elective surgery under spinal anaesthesia
- Participants
- 40 adults
- Outcome
- Spinal anesthesia-induced hypotension (SAIH)
- Follow-up
- 10 minutes after induction of spinal anaesthesia
