Abstract

Aim and objective: To study the effect of hyaluronidase in peribulbar block during cataract surgery. Background: Peribulbar anesthesia is the most popular choice for cataract surgeries. It provides globe akinesia, analgesia and and muscle relaxation. The action of hyaluronidase was first described in 1936. Hyaluronidase is the most common additive to ocular anesthesia. Hyaluronidase is an enzyme that enables the rapid onset of anesthesia and akinesia. Materials and Methods: A prospective, randomized controlled study was done to assess the effect of hyaluronidase in peribulbar block during cataract surgery in the department of Ophthalmology in a tertiary care hospital of Haryana for a period of 1 month. Total 40 patients were included in the study. Patients were randomly divided into two group, in which one group taken as case and other group as control. In one group no hyaluronidase was added but in other group hyaluronidase was added in the peribulbar block.Ocular motility was assessed at 1, 5 and 10 minutes for successful block. Results: Patients in both groups as 20 in each group, and there was no significant differences between the two groups in age and sex noted. Ocular motility score at 1 min for both groups was same. The p value comes out to be significant (p <0.05) both at 5 minutes and at 10 minutes ,showed the incidence of successful block in hyaluronidase group in which the score was <4 for achieving akinesia. Conclusion: Hyaluronidase has the advantage of adding it to the peribulbar block as it enables the rapid onset of anesthesia and akinesia with lower drug volume.
