What this trial studies

This clinical trial aims to compare the effects of individualized versus conventional blood pressure management strategies on postoperative outcomes in patients undergoing major non-cardiac surgery. Participants will be randomly assigned to either an individualized strategy, which maintains blood pressure within 20% of their baseline values, or a conventional strategy, which targets a minimum mean arterial pressure of 65 mmHg and systolic blood pressure of 90 mmHg. The study will assess the frequency of major adverse outcomes within 7 days post-surgery or before discharge. The trial reflects real clinical scenarios by allowing flexibility in perioperative management while focusing on blood pressure targets.

Who should consider this trial

Good fit: Ideal candidates include patients aged 65 and older or those aged 45 and older with a history of cardiovascular issues, undergoing non-cardiac surgery lasting at least 2 hours.

Not a fit: Patients undergoing emergency surgeries, organ transplants, or those with severe pre-existing conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative outcomes and reduced complications for patients undergoing major non-cardiac surgeries.

How similar studies have performed: Other studies have explored blood pressure management in surgical settings, but this specific individualized approach is relatively novel.
