Preoperative Carotid Doppler Ultrasound Parameters for Prediction of Post-Induction Hypotension in Elective Non-Cardiac Surgery

Condition(s) studied

Study summary

This prospective observational study aims to evaluate the predictive value of preoperative carotid Doppler ultrasound parameters, including carotid velocity-time integral (carotid VTI) and corrected carotid flow time (ccFT), for post-induction hypotension in adult patients undergoing elective non-cardiac surgery under general anesthesia. Hemodynamic instability during anesthesia induction is a common and clinically important problem associated with adverse perioperative outcomes. Carotid Doppler ultrasonography provides a rapid and non-invasive method for assessing hemodynamic status at the bedside. In this study, carotid Doppler measurements will be performed in the preoperative period and their association with post-induction hypotension will be analyzed. The results of this study may help identify patients at risk for hypotension and improve perioperative hemodynamic management.

Eligibility

Primary outcome measure(s)

• Post-induction hypotension — From anesthesia induction until 10 minutes after tracheal intubation or until the start of surgery, whichever occurs first.
  Occurrence of post-induction hypotension after anesthesia induction, defined as either a decrease in mean arterial pressure (MAP) of ≥30% from baseline or a MAP \<65 mmHg sustained for at least 1 minute.
