Participants were randomized into two groups: the oliceridine group (Group O, n = 40) and the sufentanil group (Group S, n = 40). Hemodynamic parameters (SBP, DBP, MAP, HR) were recorded at baseline, after drug administration, and post-LMA placement. Adverse events (eg, hypotension, hypertension, nausea/vomiting) were analyzed using Chi-square or Fisher’s exact tests.Results: Compared with sufentanil, oliceridine significantly reduced the hemodynamic fluctuations after laryngeal mask insertion. Specifically, the variability of mean arterial pressure (MAP) decreased ((ΔMAP: − 4.8 ± 3.4 mmHg vs − 15.7 ± 10.5 mmHg, mean difference: 10.9mmHg, 95% CI: 7.4 to 14.3 mmHg, P = 0.000). Although there was no significant difference in intubation response rate between the two drugs (7.5% vs 10.0%, P = 0.236), oliceridine demonstrated better safety profile, with no occurrence of nausea or vomiting (0% vs 7.5%, P = 0.076).Conclusion: Oliceridine may offer a safer alternative for hemodynamically fragile elderly patients during LMA anesthesia.Keywords: elderly, hemodynamic stability, hypertension, laryngeal mask airway, oliceridine, randomized controlled trial
