Systemic reactions following intraocular acetylcholine instillation
Abstract:
An 83-year-old patient undergoing intracapsular cataract extraction under local anesthesia experienced systemic reactions to intraocular acetylcholine chloride instillation. Immediately following the injection into the anterior chamber, severe bradycardia, hypotension, flushing, sweating, and difficulty in breathing were observed. The ophthalmic surgeon must be aware of such side effects and be prepared to treat them. Constant monitoring of the vital signs of the patient is suggested in all cases of intraocular surgery.
