To Compare the Incidence of Oculocardiac Reflex with Pre-Medication & Without Premedication in Strabismus Surgery.
Ophthalmol Update Jan ;12(1):37-9.

Objective: To compare the Incidence of Oculocardiac Reflex With Pre-Medication and Without Premedication In Strabismus Surgery Material and Methods: This study was a randomized control trial performed in the Department of Ophthalmology at Khyber Teaching Hospital, Peshawar form February, 2011 to October, 2011. Eighty patients of ages between 10 to 18 years were randomly divided into two groups. The patients in Group A were pre-medicated with an anticholinergic drug (atropine sulphate) while the patients in group B were not administered any pre-medications. Patients in both the groups were anesthetized with similar drugs during horizontal strabismus surgeries. Patients were monitored using blood pressure, electrocardiography and heart rate monitor. Dysrhythmias occurring during anesthesia were identified and documented in each group with collaboration with Anesthesiology Department. Results: Dysrhythmias were observed in both the groups but the incidence was very high among patients from group B. In group A 2 patients (5 percent) while in group B 25 patients (65 percent) developed dysrhythmias. In both the groups only 2 patients (3 percent) developed ventricular ectopics while 25 patients (31 percent) developed bradychardia. Conclusion: This study shows that the incidence of oculocardiac reflex is very high in patients who were not pre-medicated with an anticholinergic drug. Hence, all the patients requiring general anesthesia for eye surgeries specially squint surgery involving medial rectus should have a proper anticholinergic pre-medication.
