Condition: Hypotension on Induction · Sponsor: Ain Shams University
Baseline Measurements For the ultrasound parameters, it is the average of three readings In supine position . The investigators will continuously monitoring during induction and 10 minutes after. Hemodynamic Monitoring: * Heart rate from ECG * SpO2 * Etco2 * Blood pressure . invasive Blood pressure * The radial artery level is the site of continuous arterial pressure monitoring with an arterial catheter. * Ultrasound Measurements: The patient will be positioned in a supine position, with the right side of the neck completely exposed. The transverse part Of the main carotid artery beneath the thyroid cartilage will be precisely identified using ultrasound device (sonosite edge portablp.fojy usa)via a linear array probe (4-15 MHz), with the marker directed toward the patient's head. Thus, the sampling line will be positioned at the center of the carotid lumen, around 2 cm from the carotid bifurcation, and the electronic angle correction cursor will be pointed in the direction of blood flow. Insonation angles between the ultrasound beam and blood flow will be maintained at or \< 60°. Next, the carotid blood flow waveform will be acquired, and the consecutive stable carotid pulse Doppler flow spectrum will be determined with an optimal level of image quality. The Correction: To get the corrected carotid flow time (ccFT), the measured FT will be adjusted for the patient's heart rate (HR). A commonly used formula is Wodey's formula. A single, experienced sonographer will per…
