What this trial studies

This project investigates the effects of intentional hypotensive management using nitroglycerin during general anesthesia in patients undergoing orthognathic surgery. The study involves monitoring blood biochemical and urine parameters throughout the surgical procedure to assess renal function and identify early risk factors for acute kidney injury (AKI). By recognizing these factors early, the research aims to implement intervention strategies that could prevent postoperative AKI, contributing to Enhanced Recovery After Surgery (ERAS) goals for improved patient recovery.

Who should consider this trial

Good fit: Ideal candidates are patients classified as ASA class I to II who are undergoing oro-maxillo-facial surgery and have unlimited mouth opening.

Not a fit: Patients with chronic renal insufficiency, significant obesity, or other specified comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help prevent acute kidney injury in patients undergoing orthognathic surgery, leading to better postoperative outcomes.

How similar studies have performed: While the approach of using controlled hypotension in surgery is established, the specific focus on early detection of AKI risk factors in this context is relatively novel.
