Abstract

PURPOSE
To Compare efficacy of Peribulbar with Subtenon’s block with respect to akinesia & block related complications
METHODS
A prospective comparative study was conducted including 60 patients who were divided into Peribulbar & Subtenon’s group. One 30mL vial of 2% lidocaine with adrenaline 1:200,000 mixed with 1 vial of lyophilized hyaluronidase (1500 I.U.) was used as an anesthetic agent. Sub conjunctival haemorrhage, chemosis & Akinesia were compared between the groups.
RESULTS
Peribulbar anaesthesia provided better akinesia than subtenon’s anaesthesia. Complications like chemosis & subconjunctival haemorrhage were more common in Subtenon’s anaesthesia. However, 2 patients in the subtenon’s group required supplementary injection
CONCLUSION
Though there is increase in minor complications like chemosis & SCH with Subtenon’s compared to Peribulbar anaesthesia, Subtenon's is safe & effective alternative to the conventional Peribulbar block as it avoids needle related complications.
