ClinConnect Summary

This clinical trial is studying how certain measurements can help predict low blood pressure (hypotension) in older patients after they receive general anesthesia for elective surgery. Specifically, the researchers will use two methods: an ultrasound of the carotid artery and a measurement called the inferior vena cava (IVC) collapsibility index. These tests aim to understand better which patients might be at risk of experiencing low blood pressure after they are sedated for surgery.

To be eligible for this study, participants need to be older adults (typically aged 65 and above) who are healthy enough for surgery, as defined by specific criteria. They should not have certain health problems, such as severe heart or lung issues, significant obesity, or a history of difficult intubation (which is inserting a tube to help with breathing during surgery). If chosen to participate, individuals will undergo the ultrasound and other assessments before their surgery to help ensure their safety during the procedure. This study is not yet recruiting participants, but it aims to improve care for older patients undergoing surgery in the future.
