Comparing General Anesthesia with Preemptive IV Atropine vs General Anesthesia with Single Injection Peribulbar Block with Levobupivacaine 0.5% or Lidocaine 2% for Prevention of Oculocardiac Reflex in Children Undergoing Strabismus Surgery: Randomized Control Study

Abstract

trabismus is one of the common health problems among the children. In 1908, Aschner described a decrease in heart rate as a consequence of applying pressure directly to the eyeball. This phenomenon would eventually be termed “the oculocardiac reflex” and is defined clinically as a decrease in heart rate by 10% following pressure to the globe or traction of the ocular muscles. The reported incidence of the oculocardiac reflex varies from 14% to 90%, depending on the study, making it relatively common The incidence of the oculocardiac reflex decreases with age and tends to be more pronounced in young, healthy patients, which is clinically significant for pediatric as it is observed with greatest incidence in young healthy neonates and infants undergoing strabismus surgery.
