What this trial studies

This clinical trial aims to evaluate the effectiveness of dexmedetomidine and magnesium sulfate in preventing post-operative cognitive dysfunction (POCD) in elderly patients undergoing open abdominal surgery. The study will compare the neuroprotective effects of these two agents during general anesthesia, focusing on their impact on serum levels of CRP, a marker of neuronal degeneration. By investigating the relationship between these interventions and cognitive outcomes, the trial seeks to provide insights into improving post-surgical recovery in older adults.

Who should consider this trial

Good fit: Ideal candidates for this study are elderly patients classified as ASA physical status I, II, or III who are scheduled for open abdominal surgery under general anesthesia.

Not a fit: Patients with a preoperative MoCA score below 26 or those with a BMI over 35 kg/m² may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of cognitive dysfunction in elderly patients after surgery.

How similar studies have performed: Previous studies have shown promising results regarding the neuroprotective effects of magnesium sulfate in similar contexts, suggesting potential for success in this approach.
