Filter by:The aim of the study is to evaluate the analgesic properties of dexamethasone and to quantify the possible associated postoperative complications, such as wound infections and hyperglycaemia, in patients who underwent lobectomy, segmentectomy or atypical resection surgery with a mini-thoracotomy approach or video-assisted thoracoscopic surgery (VATS).
The prevalence of diabetes mellitus (DM) is rapidly growing worldwide. One major concern with diabetes mellitus is how it may affect vision in different ways; including the increased risk of developing cataract. Several studies have found an association between diabetes mellitus and the development of cataract. In patients with DM, cataract progression is also faster and occurs at a younger age.5 While results for modern cataract surgery are satisfactory, cataract surgery in diabetic patients carries a higher risk of peri and post-operative complications than in non-diabetic patients. Several studies have shown that the corneal endothelial count of diabetic patients is decreased, with more damage occurring to corneal endothelial cells following phacoemulsification in diabetics than in non-diabetics. This is presumed to be due to increased vulnerability of corneal endothelial cells in diabetics and a delay in the repair process. Administration of topical corticosteroids is the main method to control post-operative inflammation after phacoemulsification, however many studies have also proved the safety and efficacy of intracameral corticosteroids to control inflammation post-operatively. While intracameral triamcinolone is effective in controlling post-operative inflammation, elevation of intraocular pressure is a main concern. Dexamethasone has been found to be effective in controlling post-operative inflammation with no effect on intraocular pressure. This may be due to its rapid turnover and short half-life. No studies however have been performed to evaluate the safety and benefit of intracameral injection of dexamethasone following phacoemulsification in diabetic patients. In the present study, investigators aim to evaluate this and determine its effect on the post-operative corneal endothelial cell density and corneal thickness.
