Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Hypotensive patients
Patients who developed hypotension after the induction of spinal anesthesia.
Carotid ultrasound measurement
Pulsed-wave Doppler acquisition of the carotid artery. One acquisition will be made with the slow-speed setting (33 mm/s) and one with the medium-speed setting (66 mm/s).
Vital sign measurement
Measurement of noninvasive blood pressure, at different time points before and after the induction of spinal anesthesia.
Spinal anesthesia
Following the standard of care, the patients received spinal anesthesia. The type and dosage of the local anesthetic were at the discretion of the treating anesthesiologist.
Normotensive patients
Patients who did not develop hypotension after the induction of spinal anesthesia.
Carotid ultrasound measurement
Pulsed-wave Doppler acquisition of the carotid artery. One acquisition will be made with the slow-speed setting (33 mm/s) and one with the medium-speed setting (66 mm/s).
Vital sign measurement
Measurement of noninvasive blood pressure, at different time points before and after the induction of spinal anesthesia.
Spinal anesthesia
Following the standard of care, the patients received spinal anesthesia. The type and dosage of the local anesthetic were at the discretion of the treating anesthesiologist.
