In plain words

What the trial is, and whether it could suit you

This prospective observational study aims to evaluate whether the preoperative neutrophil percentage-to-albumin ratio (NPAR) is associated with post-induction hemodynamic vulnerability in adult patients undergoing elective major oncologic surgery under general anesthesia. NPAR will be calculated from routine preoperative laboratory results by dividing the neutrophil percentage by the serum albumin level. No additional laboratory tests, medications, invasive procedures, or changes in anesthesia management will be performed for the purposes of the study. Demographic characteristics, preoperative laboratory values, anesthetic data, and hemodynamic measurements will be recorded prospectively. Hemodynamic status will be evaluated during the period between induction of general anesthesia and surgical incision, with a maximum observation period of 20 minutes. Vasopressor use and administered
