全麻手术时由于麻醉药品的肌肉松弛作用使眼睑松弛,消除了眼睛正常的机械性眼睑闭合,常使患者在手术后出现畏光、流泪、视物不清、异物感、结膜炎、角膜干燥以及眼痛等暴露性角膜炎症状。患者暴露在眼裂部位的球结膜充血、水肿等并发症,严重者可导致角膜炎甚至角膜溃疡,甚至眼部检查发现角膜上皮点状浸润损伤,角膜荧光术染色阳性,严重者角膜上皮剥脱,发生角膜穿孔和化脓性眼内炎,如果治疗和护理不当可导致角膜溃疡,甚至视力丧失[1]。因此,全身麻醉期间术中及时有效的预防极为关键,我院手术室通过术中使用红霉素眼膏涂眼,并使用3M胶布将眼睑充分闭合后粘上,对预防暴露性角膜炎的发生取得了较满意的效果。
General anesthesia surgery due to relaxation of the muscle relaxation of the eyelid relaxation, eliminating the normal eye mechanical eyelid closure, often in patients with photophobia after surgery, tearing, blurred vision, foreign body sensation, conjunctivitis, corneal dryness Eye irritation and other symptoms of keratitis. Patients with conjunctival hyperemia, edema and other complications of the conjunctival hyperemia, severe cases can lead to keratitis or even corneal ulcers, and even corneal epithelial punctate injury, corneal fluorescein staining, severe corneal epithelial exfoliation, Corneal perforation and purulent endophthalmitis occur, leading to corneal ulceration and even loss of vision if treatment and care are inadequate [1]. Therefore, during the general anesthesia timely and effective prevention is critical, the operating room in our hospital through intraoperative use of erythromycin eye ointment and 3M adhesive tape to fully close the eyelid after the stick, to prevent the occurrence of exposure keratitis Made more satisfactory results.
