Efficacy of Eyelid Taping with and without Ocular Lubricants in Patients Receiving General Anaesthesia: A Prospective Interventional Study

Abstract

Introduction: Corneal Abrasion (CA) is the most common ophthalmic complication that occurs after General Anaesthesia (GA) in non ocular surgeries. GA results in reduced basal tear volume, loss of light reflex, and lack of pain perception, resulting in corneal drying. This makes the cornea susceptible to abrasion and keratitis. Research suggests that preventing corneal mechanical exposure and providing artificial tears can help mitigate these risks. Aim: The aim of this study was to assess the efficacy of eye taping with and without Hydroxypropyl Methylcellulose (HPMC) drops in preventing perioperative CA. Materials and Methods: This prospective comparative interventional study was conducted in the Department of Anaesthesia, Justice Hegde KS Charitable Hospital in Mangaluru, India, from June 2021 to November 2021. A total of 122 patients who underwent GA for non ocular surgeries lasting more than 45 minutes were grouped into group T or group D, depending on whether their eyes were only taped during GA (T) using hypoallergenic adhesive tape or had HPMC drops instilled in their eyes along with tape (D). Participants were evaluated 2 and 12 hours after the end of GA in the postanaesthesia care unit using a questionnaire to assess eye symptoms. Conjunctival hyperaemia and chemosis were evaluated using scoring systems. Other parameters noted included age, gender distribution, type, and duration of surgery. Statistical analysis using the chi-square test/likelihood ratio was performed to assess the association between the eye protection method used and postsurgical outcomes. Results: Out of the 122 patients who received either of the two eye protection methods under GA, 68 (55.7%) were females and 54 (44.3%) were males. A total of 85 (69.6%) were between the ages of 20-60 years, while 29 (23.8%) were above the age of 60 years. There was no statistically significant association found between the age or gender of the patients and the eye protection method used. No statistically significant difference was noted between the duration, type of surgeries, and the eye protection method used in this study. There was no statistical significance (p-value>0.05) noted with respect to the conjunctival hyperaemia and chemosis scoring in the two groups. However, 15 (24.6%) patients in group D were found to have adhesive lids two hours postsurgery. There was an association (p-value<0.05) between the occurrence of adhesive lids at two hours postsurgery and the eye protection method used. Conclusion: Eye protection is mandatory in all non ophthalmic cases under GA. Both eyelid taping alone and eyelid taping with HPMC drops are equally effective in preventing perioperative ocular injury
