Using propofol for anesthesia induction in high-risk patients

Does Induction of Anesthesia with Target-controlled Propofol Infusion Reduce the Risk of Post-induction Hypotension in High-risk Patients?

Not applicable Interventional Acibadem University · NCT06535230

This study is testing whether using a special method to give propofol for anesthesia can help high-risk patients avoid low blood pressure during major surgeries compared to the usual way of giving it.

What this trial studies

This study aims to compare the incidence of hypotension following anesthesia induction in high-risk patients using a target-controlled infusion (TCI) of propofol versus standard manual induction techniques. It focuses on patients with higher American Society of Anesthesiologists (ASA) risk scores, who are more susceptible to hypotension during anesthesia. The study builds on previous findings that suggest TCI may reduce the risk of hypotension compared to traditional methods. Participants will undergo major elective surgeries and will be monitored closely for blood pressure changes during the induction process.

Who should consider this trial

Good fit: Ideal candidates are patients classified as ASA physical status 3-4 who are undergoing major elective surgery and require intra-arterial blood pressure monitoring.

Not a fit: Patients who are under 18 years of age, have lower ASA physical status scores, or present with certain medical conditions such as severe valvular heart disease or drug addiction may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the occurrence of hypotension in high-risk patients during anesthesia induction.

How similar studies have performed: Previous studies have indicated that target-controlled infusions can reduce hypotension risks, suggesting a promising approach that may be further validated in this high-risk population.
