  "abstract": "Background and Objectives: This study examined four pre-specified relationships in 47 preschool children (aged 4-7) undergoing adenotonsillectomy: the perioperative change in salivary cortisol in relation to postoperative emergence delirium (PAED) and pain (FLACC) scores, defined a priori as the primary endpoint, and, as secondary, hypothesis-generating endpoints, the associations between preoperative anxiety (mYPAS) and salivary cortisol, between cortisol and gastric antral cross-sectional area (CSA, used as a surrogate for gastric volume), and between intraoperative anesthesia depth (PSI) and PAED scores. Materials and Methods: Preoperative anxiety was assessed using the mYPAS scale, followed by salivary cortisol sampling and ultrasonographic measurement of the gastric antral cross-sectional area (CSA, used as a surrogate for gastric volume). Postoperative recovery was monitored using PAED and FLACC scoring systems at 0, 15, and 30 min. Results: A moderately strong positive correlation was identified between mYPAS anxiety scores and preoperative salivary cortisol levels. However, no statistically significant correlation was detected between preoperative cortisol and gastric antral CSA. Furthermore, linear mixed-effects modeling did not detect a statistically significant association between the change in cortisol levels and postoperative PAED scores. Conclusions: The study confirms that preoperative behavioral anxiety in children is reflected in physiological markers like salivary cortisol. However, no statistically significant association was detected between these cortisol levels and gastric antral CSA, postoperative emergence delirium, or postoperative pain (PAED/FLACC scores) in this cohort. While mYPAS remains a valid tool for assessing preoperative anxiety, our findings do not support cortisol or gastric antral CSA as reliable predictors of post-anesthesia outcomes in this pediatric population; larger studies are needed before concluding that no such relationship exists.",
