Abstract：
The objective of the study was to assess the validity of the NASA-TLX score in rating the workload of pediatric robotic operations.
The workload of 230 pediatric gastrointestinal and thoracic robotic operations was rated using the NASA-TLX score. The difference between the high workload group and the low workload group in each subscale of the NASA-TLX score was analyzed. The correlation of each subscale with the total workload score in the high workload group and low workload group was also analyzed. A logistic regression analysis was subsequently conducted to assess the effects of different factors (sex, age, weight, procedure duration, procedure specialties, combined malformation and blood loss) on the workload.
The average NASA-TLX score was 56.5 ± 5.1 for the total group, 56.9 ± 5.0 for the gastrointestinal group and 54.6 ± 4.8 for the thoracic group, p = 0.007. The score of the high workload group was 62.7 ± 3.2, while it was 50.6 ± 2.7 for the low workload group (p < 0.001). The score on each subscale was also significantly different between the high and low workload groups. In the high workload group, a stronger correlation was observed between the total score and TD and Fr and a lower correlation with MD and Pe. In the low workload group, all six subscales showed a moderate correlation with the total score. A multivariate logistic regression analysis revealed that the procedure duration was an independent influencing factor for a higher workload score.
NASA-TLX is a valid tool to rate the surgeon\'s workload in pediatric robotic surgery. A longer operative time contributes to a higher workload.

摘要：
目的：该研究的目的是评估NASA-TLX评分在评估儿科机器人手术工作量方面的有效性。
方法：使用NASA-TLX评分对230例儿科胃肠和胸部机器人手术的工作量进行了评估。分析了NASA-TLX评分的每个子量表中高工作量组与低工作量组之间的差异。还分析了高工作量组和低工作量组中每个子量表与总工作量得分的相关性。随后进行了逻辑回归分析，以评估不同因素(性别，年龄,体重,程序持续时间,程序专业，合并畸形和失血)的工作量。
结果：全组NASA-TLX平均得分为56.5±5.1，胃肠组56.9±5.0,胸组54.6±4.8,p=0.007。高工作负荷组为62.7±3.2,低工作负荷组为50.6±2.7(p<0.001)。高工作量组和低工作量组之间的每个子量表得分也存在显着差异。在高工作量组中，总分与TD和Fr之间的相关性更强，与MD和Pe的相关性较低。在低工作量组中，所有6个分量表显示与总分有中等相关性.多因素logistic回归分析显示，手术时间是较高工作量得分的独立影响因素。
结论：NASA-TLX是评估外科医生在儿科机器人手术中工作量的有效工具。较长的操作时间导致较高的工作量。
