What this trial studies

This study focuses on the prevention and treatment of intraoperative hypotension, a condition that can lead to serious complications during and after surgery. It aims to establish effective strategies based on maintaining a normal peripheral perfusion index (PPI) to manage blood pressure during anesthesia. The study will monitor patients undergoing general anesthesia for non-cardiac surgeries lasting more than two hours, ensuring that their mean arterial pressure remains above 65 mmHg. By implementing these strategies, the study seeks to reduce the risks associated with low blood pressure during surgical procedures.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 65 years and older who are undergoing general anesthesia for procedures lasting more than two hours and can communicate in Mandarin.

Not a fit: Patients with a history of diabetes, vascular diseases, or those with cardiac function class II and above may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of complications related to intraoperative hypotension, improving surgical outcomes for patients.

How similar studies have performed: Other studies have shown promising results with similar approaches to managing intraoperative hypotension, indicating that this methodology is both relevant and potentially effective.
