改良体位对甲状腺手术后患者眼部并发症的预防效果

目的：探讨甲状腺术中采用改良体位对患者眼部并发症的影响。方法：采用随机对照原则，将74例甲状腺择期手术患者，随机分成观察组和对照组，每组各37例。对照组采用常规甲状腺手术体位，观察组采用改良体位，观察术后患者眼压变化情况，眼部不适发生情况，视野变化情况。结果：术后两组患者的眼压较术前均呈明显的上升，但观察组术后眼压明显低于对照组，差异具有统计学意义（P<0.05）。对照组术后眼部干涩、畏光、异物感发生率高于观察组，差异有统计学意义（P<0.05）。术后对于视野的影响，对照组明显高于观察组（P<0.05）。结论：改良体位可以明显减少甲状腺术后眼部并发症的发生。

Prophylactic effect of modified posture on ocular complications in patients undergoing thyroid surgery

Objective: To investigate the effect of modified posture on ocular complication during thyroid surgery.Methods: 74 patients with selective thyroid surgery were randomly divided into control group and observation group with 37 cases in each group. The traditional thyroid operation position was used in the control group and the modified position was used in the observation group. The changes of intraocular tension and the occurrence of ocular discomfort，visual field changes were observed. Results: Compared with the index before operation, the intraocular pressure of the two groups increased significantly, but the intraocular pressure in the observation group was significantly lower than that in the control group, the difference was statistically significant（P<0.05）. The incidence rate of complications as dye dryness, photophobia, foreign body sensation in the control group was higher than that of observation group (P<0.05). The effect on visual field after operation in the control group was higher （P<0.05）. Conclusion: Modified posture can significantly reduce the incidence of postoperative eye complication of thyroid.
