500例患儿麻醉后躁动的多因素分析

目的：分析该院2年500例患儿麻醉手术后躁动发生的影响因素。方法该院A S A分级为Ⅰ～Ⅱ级的500例患儿，根据麻醉手术后苏醒的躁动情况分为躁动组和非躁动组。对患儿年龄、性别、体质量、术前焦虑分级、所患疾病种类、ASA分级、麻醉用药种类及剂量、插管、麻醉时间、停药后患儿苏醒时间、患儿苏醒后躁动情况做Logistic回归分析。结果500例患儿，术后躁动153例，占总数的30．6％；Logistic回归分析得出患儿年龄较大、性别、应用氯胺酮等项目回归系数为负，患儿体质量、术前焦虑分级、七氟醚麻醉、插管等项目回归系数为正；ROC曲线下面积为0．850。结论患儿体质量、术前焦虑分级、气管插管、七氟醚麻醉可以增加患儿麻醉手术后躁动发生率，而患儿年龄较大、女性患儿、应用氯胺酮可以减少麻醉手术后躁动发生率。

The incidence and risk factor for agitation after the general anesthesia from 500 pediatric patients

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 .
