简要总结
Spinal anesthesia, though safe and effective, often leads to hypotension, which can cause serious complications. Conventional preventive strategies like fluid preloading or vasopressors have limited success and potential risks. Therefore, a simple, non-invasive method to predict post-spinal hypotension is needed.
This prospective observational study investigates whether ultrasonographic measurements of the internal jugular vein (IJV), particularly the collapsibility index, can predict the occurrence of hypotension following spinal anesthesia in women undergoing elective total abdominal hysterectomy.
A total of 120 patients (ASA I–II, aged 35–65 years) will be studied. Pre-anaesthetic ultrasonographic IJV parameters (maximum and minimum diameter, area, and collapsibility index) will be recorded and correlated with intraoperative blood pressure changes. The primary outcome is the incidence of post-spinal hypotension; secondary outcomes include fluid requirements and vasopressor use.
Statistical analysis will assess sensitivity, specificity, and predictive values of IJV ultrasonography. If validated, this technique could help anesthesiologists identify high-risk patients and initiate timely preventive measures, improving patient safety
