Preoperative serum miR-431-5p as a predictive biomarker for perioperative respiratory adverse events in children undergoing general anesthesia.
Pediatric perioperative respiratory adverse events (PRAE) pose significant risks during general anesthesia. Reliable predictive biomarkers reflecting early airway vulnerability remain scarce. This study aimed to evaluate the predictive value of miR-431-5p for PRAE and explore its underlying cellular mechanisms. A retro...
