Using Ultrasound of the Internal Jugular Vein to Predict Low Blood Pressure After Anesthesia in Older Adults Undergoing Laparoscopic Colorectal Surgery

What this Trial Is About

Researchers are investigating the internal jugular vein IJV collapsibility index as a way to predict low blood pressure after general anesthesia in older adults undergoing laparoscopic colorectal surgery. The IJV collapsibility index is considered a practical alternative to the inferior vena cava collapsibility index because it can be measured easily at the bedside using ultrasound. Previous studies have shown that IJV collapsibility correlates with central venous and right atrial pressures. This observational study involves assessing the IJV collapsibility index through ultrasound to predict hypotension occurring within the first 15 minutes after anesthesia induction. Participants are patients aged 60 years or older scheduled for elective laparoscopic colorectal surgeries under general anesthesia. The study does not involve administering treatments but focuses on monitoring and measuring the IJV collapsibility index. Participants will have ultrasound assessments to measure the IJV collapsibility index before anesthesia. Researchers will record blood pressure changes after induction to determine the indexs predictive value for hypotension. The main measure is the optimal ultrasound cut-off value of the IJV collapsibility index within the first 15 minutes after anesthesia. Study participation lasts through the surgical procedure and immediate monitoring period.
