To compare and assess the efficacy of eye ointment and adhesive tape for protection of eyes under general anaesthesia.
One hundred and fifty patients (300 eyes) undergoing general anaesthesia for > 90 min for non-ophthalmic procedures were divided randomly into three groups (C, T & O). Eyes in group C were left as control, in group T hypoallergen tape was applied and in group O chloromycetin ointment was used. In all eyes basal tear production and visual acuity was assessed and corneal examination was carried out after fluorescein staining both before and after surgery. All the patients were subjected to a conventional general anaesthesia technique.
General anaesthesia reduced basal tear production irrespective of the method of eye protection used (P < 0.0001). The overall incidence of corneal epithelial defects was 10%, of which 90% occurred in the control group, 6.6% in the tape and 3.3% in the ointment group. There was no difference between pre and post operative visual acuity (P : NS). Corneal injuries were more common in the dependent eye in the lateral position and the incidence of corneal epithelial defects did not alter with increase in duration of surgery.
During general anaesthesia eyes need protection either by tape or ointment as incidence of corneal injuries is greater in unprotected eyes.
比较和评估眼膏与胶带在全身麻醉下保护眼睛的效果。
150例（300只眼）因非眼科手术接受全身麻醉超过90分钟的患者被随机分为三组（C组、T组和O组）。C组眼睛作为对照，T组应用低敏胶带，O组使用氯霉素眼膏。所有眼睛在手术前后均评估基础泪液分泌和视力，并在荧光素染色后进行角膜检查。所有患者均采用传统全身麻醉技术。
无论采用何种眼部保护方法，全身麻醉均会降低基础泪液分泌（P < 0.0001）。角膜上皮缺损的总发生率为10%，其中90%发生在对照组，胶带组为6.6%，眼膏组为3.3%。术前和术后视力无差异（P：无统计学意义）。角膜损伤在侧卧位时的下垂眼更常见，且角膜上皮缺损的发生率不会随手术时间延长而改变。
在全身麻醉期间，眼睛需要用胶带或眼膏进行保护，因为未保护的眼睛角膜损伤发生率更高。
