Does preoperative arterial stiffness measured by Doppler ultrasonography predict induction-related hypotension in patients undergoing elective cardiac surgery?
Preoperative arterial stiffness and stiffness index measured by Doppler ultrasonography do not reliably predict hypotension during anesthesia induction in patients undergoing cardiac surgery.
p-value: p=>0.05 for association of arterial stiffness measures with induction hypotension
Preoperative arterial stiffness and stiffness index measured by Doppler USG did not predict anesthesia induction hypotension in cardiac surgery patients. Their clinical utility in this context appears limited, warranting further investigation.
Aydemir et al. (Fri,) conducted a observational in Adult patients aged 18-85 undergoing elective open cardiac surgery with left ventricular ejection fraction ≥35% and no arrhythmias or end-stage renal disease (n=121). Preoperative arterial stiffness measurement via carotid-femoral pulse wave velocity and β-index using Doppler ultrasonography vs. Not applicable (observational design) was evaluated on Development of hypotension during anesthesia induction (systolic arterial pressure <90 mmHg) (p=>0.05 for association of arterial stiffness measures with induction hypotension). Preoperative arterial stiffness measured by pulse wave velocity and stiffness index did not predict anesthesia induction hypotension in cardiac surgery patients (p>0.05).
