Randomized Controlled Trial Clinical TrialOculocardiac reflex during retinal surgery using peribulbar block and nitrous narcotic anesthesia.
This study was designed to examine the effects of local and general anesthesia on the oculocardiac reflex (OCR) in adults during retinal detachment surgery, with an aim of determining the safest type of anesthesia and on which extraocular muscle traction causes a higher incidence of OCR. ⋯ This study showed that local anesthesia produces less bradycardia and ectopic arrhythmias and, therefore, may be safer and better than general anesthesia for surgeries in which traction of extraocular muscles is required.
