• Status: Unknown status
• Trial end date: 2018-01-31
• Target enrollment: 0
• Participant gender: All

Summary

Most of the ophthalmic procedures are performed under local anesthesia as the patient is often elderly and with diseases. This may increase the risk of morbidity and mortality under general anesthesia. Different eye blocks have been practiced with great success. Moreover, it is associated with less hemodynamic instability, less respiratory depression, better postoperative pain relief, and less nausea and vomiting than general anesthesia. It is also associated with a reduction in stress response, maintained oxygen saturation and cardiovascular stability, in addition to the production of good akinesia and anesthesia alleviating occulo-medullary reflexes, all make local anesthesia more superior and safe technique.
