761例患者散瞳后瞳孔变化时间的观察与研究

目的观察瞳孔散大时间及瞳孔散大后的稳定时间，指导护士准确掌握散瞳时间，使患者瞳孔符合眼科检查与手术的需要。方法对761例患者用复方托品酰胺进行散瞳，分别于散瞳前和散瞳后10，20，30，40，50，60min测量瞳孔直径。结果散瞳前与散瞳后10，20，30，40min组间的两两比较，差异均有统计学意义（P〈0．01），而散瞳后40min与散瞳后50～60min组间的两两比较差异均无统计学意义（P〉0．05）。结论散瞳后40min瞳孔即处于稳定状态，护理人员应在眼科检查或手术前40min为患者散瞳。

Clinical study of 761 cases' pupils transformation period after mydriasis

Objective We executed routine mydriasis on 761 cases pre-examine and pre-operate, and recorded the mydriasis time including the resistant time after mydriasis. In this way, we can guide our nurses to handle the mydriasis time accurately and to keep puiple at the optimal dilate state during examing and operating. Methods A total af761 cases were executed mydriasis with Compound Tropicamide. The pupil diameters were measured after using the mydriatie 10 minutes, 20 minutes , 30 minutes, 40 minutes, 50 minutes and 60 minutes respectively. All the data were analyzed with SPSS 13.0 software. Results The pupil diameter showed statistic difference(P <0. 01 ) between the post 10 minutes and post 20 minutes group,between the post 20 minutes and post 30 minutes group and between the post 30 minutes and post 40 minutes groups, while among those post 40 minutes, post 50 minutes and post 60 minutes group, there were no statistic difference (P> 0. 05). Conclusions 40 minutes after mydriasis, the puiple will be at the stable dilate state. So 40 minutes will be the optimal mydriasis time before operation.
