【摘要】 目的 探討癲癇患者注意功能受損的特點。 方法 2008年12月-2009年12月選取69例癲癇患者作為病例組，35例正常人作為對照組，分別用持續操作任務實驗（continuous performance test，CPT）、斯特魯普實驗（Stroop）和雙任務實驗測查持續注意、選擇注意和分散注意功能。 結果 與對照組相比，病例組CPT反應時延長，漏報率增加（Plt;0.05）；Stroop實驗沖突條件下反應時延長，沖突、一致和中性條件下錯誤率增加，沖突和中性條件下的反應時干擾量和錯誤率干擾量增加（Plt;0.05）；雙任務比單任務劃銷方格數目減少，字符串正確率減少，雙任務減退程度增加（Plt;0.05）。 結論 癲癇患者的持續注意、選擇注意和分散注意功能均受損。【Abstract】 Objective To observe the damages of attentive function in the patients with epilepsy. Methods From December 2008 to December 2009, 69 patients with epilepsy and 35 healthy people were selected as the patients group and control group. All the selected ones underwent continuous performance test (CPT), Stroop test and dual task, respetviely, to assess their sustained attention, selected attention and divided attention. Results In CPT, the reaction time prolonged and the omission rate increased significantly in the patient group compared with those in the control group (Plt;0.05). In Stroop test, the reaction time in the patients group prolonged under incongruous condition, and error rate increased under incongruous, congruous and neutral conditions. The reaction time interfered effects and error interfered effects increased under incongruous and neutral conditions (Plt;0.05); the boxes crossed and right rate of digit strings decreased and decrement increased during dual task than single task in the patient group (Plt;0.05). Conclusion The sustained attention, selected attention and divided attention of patients with epilepsy are impaired.
Objective To evaluate the effect of visual and audiovisual distraction on anxiety and acceptance levels among patients undergoing colonoscopy. Methods A total of 180 consecutive patients undergoing colonoscopy were randomly divided into three groups: group A received visual distraction; group B received audiovisual distraction; and group C received routine care alone. Levels of anxiety and willingness to accept the same intervention if the procedure needed to be repeated were compared among the three groups. Results The reduction of anxiety score after colonoscopy in group A and group B was greater than that in group C, but the difference was not statistically significant. The rate of willingness to accept the same intervention if the procedure needed to be repeated was significantly different among the three groups: the rates for group A and group B were higher than for group C (Plt;0.05). Conclusions Both visual distraction and audiovisual distraction can significantly improve patients’ acceptance of colonoscopy. Visual distraction and audiovisual distraction have no significant effect on reducing anxiety.
