Lower drug dose works just as well to prevent dangerous blood pressure drop in elderly surgery

This study tested whether a lower dose of the drug norepinephrine (0.07 mcg/kg/min) works as well as a higher dose (0.1 mcg/kg/min) to prevent dangerously low blood pressure in elderly patients (over 65) during hip surgery with spinal anesthesia. The trial included 84 patients and measured average blood pressure, as well as episodes of low blood pressure, high blood pressure, and slow heart rate. The goal is to find a safer, effective dose for this vulnerable group.
