FEATURES OF REGIONAL ANESTHESIA AND POSSIBLE COMPLICATIONS IN OPHTHALMIC SURGERY
In ophthalmic surgery, the choice of the method of anesthesia presents certain difficulties for both the anesthesiologist and the ophthalmologist. According to world statistics, the most frequently performed ophthalmic operations are performed in patients of the older age group who have concomitant chronic somatic diseases (diabetes mellitus, hypertension, atherosclerosis, etc.). It is advisable to use local anesthesia in the elderly, as well as in patients with severe co-morbidities or contraindications to general anesthesia. The review presents the characteristics of local anesthetics and the types of local anesthesia used in ophthalmic surgery (vesicular blockade, facial nerve blockade, retrobulbar anesthesia, peribulbar anesthesia, instillation or topical anesthesia). Also in the article, possible complications of these methods of regional anesthesia, their prevention and the principles of emergency care in case of their occurrence are described. Particular attention in the review is given to the toxicity of local anesthetics.
