Summary
During medical procedures performed under local anesthesia with sedation, such as angioplasty, the eyes may become dry because normal blinking and tear production can be reduced. Dexmedetomidine is a commonly used sedative that provides comfort and pain relief while allowing patients to breathe on their own. However, there is limited information about how dexmedetomidine affects tear production and eye comfort after procedures.
This study aims to evaluate whether sedation with dexmedetomidine affects tear production compared with standard sedative medications used during angioplasty. Adult patients undergoing angioplasty under local anesthesia will be randomly assigned to receive either dexmedetomidine sedation or standard sedation. Tear production will be measured using the Schirmer test before the procedure, shortly after the procedure, and 12 hours later. Patients will also be asked about eye dryness or discomfort, and any eye-related or sedation-related side effects will be recorded.
The results of this study may help improve eye safety and comfort in patients receiving sedation during angioplasty and guide the selection of sedative medications in clinical practice.
