Objective To develop expert consensus on perioperative thirst management in children, and provide references for stan-dardized assessment and nursing interventions for perioperative thirst. Methods Relevant literature on perioperative thirst in children was systematically searched. Based on evidence synthesis and clinical experience from pediatric nursing specialists, a preliminary consensus was developed using an evidence-based approach. Two rounds of Delphi expert consultation and an online expert meeting were conducted to revise and finalize the consensus. Results A total of 20 experts participated in the consultation, with a response rate of 100% in both rounds. The expert authority coefficient was 0.92. Kendall′s coefficient of concordance was 0.253 and 0.265 in the two rounds, respectively (both P<0.05). The final consensus covered six domains: perioperative influencing factors of thirst, assessment tools, assessment timing, target population, intervention strategies, and health education. Conclusion The developed expert consensus demonstrates sound scientific rigor and clinical applicability. It provides standardized guidance for perioperative thirst management in children and may help alleviate thirst-related discomfort.
