ABSTRACT
Objective To identify the incidence and risk factors that are associated with agitation after general anesthesia from 500 pediatric patients .Methods Data about any kinds of the index from 500 pediatric patients ,ASA Ⅰand Ⅱ ,receiving gen‐eral anesthesia were recorded .such as the age ,sex ,weight ,anxious before the anesthesia ,kinds of the disease ,class of ASA ,kinds and dosage of the anesthesia drug ,such as ketamine ,propfol ,sevoflurane ,fentanyl ,the intubation ,length of anesthesia time ,the re‐covery time and the agitation grade .According to the agitation grade ,all the patients divided into two group ,the agitation group and the non‐agitation group .Logistic regression with a descending stepwise algorithm was performed to identify independent variables . The discriminative power of the Logistic regression model was checked with a receiver operating characteristic curve .Results Agi‐tation meeting the predefined criteria occurred in 153 patients(30 .6% ) .The Logistic analysis identified the following varables to be associated with agitation after the anesthesia:age ,sex ,weight ,anxious before the anesthesia ,the use of the ketamine and the sevoflurane ,the intubation .The agitation correlation coefficients for the age ,sex ,and the use of the ketamine were negative ,other‐wise the weight ,anxiety ,the use of sevoflurane and the intubation were positive .The area of ROC was 0 .850 .Conclusion This study contributes to the identification of patients with a high risk for agitation after general anethesia .The index of the age ,sex , weight ,anxious before the anesthesia ,the use of the ketamine and the sevoflurane ,the intubation should be comprehensive evalua‐ted .
