How blood vessel properties affect anesthesia-related low blood pressure in very young and older patients
Official title: Vascular Determinants of Anesthesia-Induced Hypotension at the Extremes of Age
Funded at Johns Hopkins University · NIH-10898716 · Data updated 2026-11-12
This study is looking into why babies and older adults often have low blood pressure when they are put under anesthesia, so we can find better ways to keep them safe during surgery.

Who could benefit from this research
✓Could help
Ideal candidates for this research are infants, children, and older adults who are scheduled for surgeries requiring general anesthesia.
✕Less likely to help
Patients who are not undergoing surgery or those outside the age extremes (neonates and older adults) may not benefit from this research.
What this research studies
This research investigates the reasons why very young patients (like infants) and older adults are more likely to experience low blood pressure during anesthesia. By using both laboratory and animal studies, the researchers aim to uncover the unique characteristics of blood vessels in these age groups that contribute to this problem. Understanding these mechanisms could help improve anesthesia safety and outcomes for vulnerable populations. The findings could lead to better strategies for managing blood pressure during surgeries.
Why it matters
Potential benefit: If successful, this research could lead to improved anesthesia techniques that reduce the risk of low blood pressure in very young and older patients during surgery.
How similar studies have gone: Previous research has indicated that understanding vascular responses in different age groups can lead to improved anesthesia practices, suggesting potential success for this approach.
