Background and objective Eye surgeries are very common nowadays.
Most surgeries, including cataract surgeries, can be safely performed in an outpatient setting using local anesthesia.
Levobupivacaine, a levorotatory isomer of the racemic mixture of bupivacaine, has been used at regional blocks, including local eye blockades.
Dexmedetomidine, a potent, highly selective and specifi c α2 -adrenoreceptor agonist, with both sedative and analgesic effects and no respiratory depression, is used as an adjuvant to local eye anesthesia to prolong the analgesic duration of the local anesthetic used.
We expected that the addition of dexmedetomidine to levobupivacaine would increase both sensory and motor block durations compared with levobupivacaine alone.
Patients and methods In our study, a total of 80 patients of both sexes, aged 50–70 years, belonging to the American Society of Anesthesiologists (ASA) grade I and II, and scheduled for phacoemulsifi cation cataract surgery were randomly allocated into one of two study groups: the levobupivacaine group (group L), in which 40 patients received 3 ml of 2% lidocaine with 10 IU/ml of hyaluronidase + 3 ml of 0.5% levobupivacaine+1 ml of normal saline; and the levobupivacaine dexmedetomidine group (group LD), in which 40 patients received 3 ml of 2% lidocaine with 10 IU/ml of hyaluronidase+3 ml of 0.5% levobupivacaine+1 ml of dexmedetomidine (100 μg).
Results There was no signifi cant difference between the two groups regarding the onset times of lid akinesia, globe anesthesia, and globe akinesia (P>0.05).
The duration of globe anesthesia, lid akinesia, and globe akinesia in the dexmedetomidine group was signifi cantly longer than in the levobupivacaine group (P < 0.001).
In group LD, the fi rst analgesic requirement was signifi cantly delayed and the total analgesic consumption in the fi rst 24 h was signifi cantly lower compared with group L (P < 0.0001 for both).
Conclusion The addition of 100 μg dexmedetomidine as an adjuvant to 2% lidocaine with 10 IU/ml of hyaluronidase and 0.5% levobupivacaine in peribulbar anesthesia for cataract surgery signifi cantly increases the duration of peribulbar block and improves the analgesic duration, without signifi cant side effects, and signifi cantly decreases the intraocular pressure.
