A quasi-experimental design with two groups of preschool children was used to determine if surgical preparation offered at two different time periods would result in different levels of state anxiety and posthospital behavioral upset. Twenty-three children (3 to 6 years of age) were studied. The children in one group were prepared the afternoon before surgery, and the children in the other group were prepared the morning of surgery. The same surgical preparation program was given to all the children by the principal investigator. The state anxiety level of each child was assessed at six time points during the ambulatory surgical experience. The posthospital behavioral upset of each child was also measured. The parent of each child responded to a 27-item questionnaire one week after discharge. Analysis of the observation and questionnaire data indicated that the children who were prepared the afternoon before surgery did not differ significantly in state anxiety or posthospital behavioral upset from the children who were prepared the morning of surgery. Also, the levels of anxiety of the children in the two preparation groups did not vary significantly with the type of surgery. The state anxiety mean score of the children in the morning preparation group at each time point was lower than the mean score of the children in the afternoon preparation group at each time point. Replication of the study with a larger sample size is recommended.
采用两组学龄前儿童的准实验设计，以确定在两个不同时间段进行手术准备是否会导致不同程度的状态焦虑和术后行为困扰。对23名3至6岁的儿童进行了研究。一组儿童在手术前一天下午进行准备，另一组儿童在手术当天上午进行准备。主要研究者对所有儿童采用相同的手术准备方案。在门诊手术过程中的六个时间点评估每个儿童的状态焦虑水平。还对每个儿童的术后行为困扰进行了测量。每个儿童的家长在出院一周后对一份27项问卷进行了回答。对观察和问卷数据的分析表明，在手术前一天下午进行准备的儿童与在手术当天上午进行准备的儿童在状态焦虑或术后行为困扰方面没有显著差异。此外，两个准备组儿童的焦虑水平也不会因手术类型而有显著差异。上午准备组儿童在每个时间点的状态焦虑平均得分低于下午准备组儿童在每个时间点的平均得分。建议用更大的样本量重复该研究。
