Peribulbar Block Clinical Trial
Official title:
Ophthalmic Artery Resistance Index After Peribulbar Block in the Presence of Epinephrine
Evaluate ophthalmic artery flow by echo-Doppler before and after peribulbar block with lidocaine in presence or absence of epinephrine.
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.
