EASIX and Post-Induction Hypotension in Frail Adults Undergoing Non-Cardiac Surgery
Official title: Evaluation of the Relationship Between Endothelial Activation and Stress Index (EASIX) and Post-Induction Hypotension in Frail Patients Undergoing Non-Cardiac Surgery: A Prospective Observational Cohort Study
Run by Konya City Hospital · NCT07642765 · Data updated 2026-11-12
This study tests whether the EASIX score, calculated from routine labs, can predict post-induction low blood pressure in frail adults having elective non-cardiac surgery under general anesthesia.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 or older with frailty (CFS ≥4) scheduled for elective non-cardiac surgery under general anesthesia and available preoperative lab values for EASIX.
✕Probably not a fit
Patients without frailty (CFS <4), those undergoing cardiac or emergency surgery, or those lacking necessary preoperative labs may not benefit.

What this trial studies
This prospective observational cohort looks at whether the preoperative EASIX score is associated with post-induction hypotension (PIH) within 15 minutes after anesthesia induction in frail adults. 160 patients with Clinical Frailty Scale of 4 or higher will be enrolled, and mean arterial pressure will be recorded every 2 minutes during the first 15 minutes post-induction. EASIX is computed from LDH, creatinine, and platelet count obtained within 24 hours before surgery. A standardized induction protocol is used, with ongoing monitoring and documented outcomes including PIH and the performance of EASIX as a diagnostic test. Multivariable analysis will adjust for age, sex, ASA class, baseline MAP, antihypertensive use, fasting duration, and induction doses to explore independent associations and potential interactions with frailty level.
Why it matters
Potential benefit: If successful, EASIX could help identify frail patients at risk of PIH and guide perioperative planning to reduce hypotension-related complications.
How similar studies have gone: Previous research in perioperative care has shown interest in biomarkers predicting hemodynamic instability, but this exact EASIX-centric approach in frail, non-cardiac surgery is relatively novel.
