Clinical Trial Summary

Evaluate ophthalmic artery flow by echo-Doppler before and after peribulbar block with lidocaine in presence or absence of epinephrine.

Description:

There are controversies regarding the ophthalmic artery (OA) flow after peribulbar block with the addition of epinephrine. Therefore, we aimed to evaluate OA flow by echo-Doppler before and after peribulbar block with lidocaine in presence or absence of epinephrine.

Fifty-six patients that were eligible for cataract phacoemulsification surgery were selected. Patients were divided into two groups: group 1 - Peribulbar block with lidocaine and 1/200.000 epinephrine; group 2 - Peribulbar block with lidocaine in the absence of epinephrine. The resistance index (RI) of OA was evaluated using echo-Doppler before and 10 min after the peribulbar block.
