We have assessed the effect of two concentrations of hyaluronidase on the quality of peribulbar block, using a low volume, single injection technique. We studied 200 patients undergoing elective intraocular surgery, allocated randomly to one of three groups. Group 1 (n = 50) received peribulbar block with 5 ml of a 1:1 mixture of 0.5% plain bupivacaine and 2% plain lignocaine. Group 2 (n = 75) ...

We have studied the pharmacokinetics and effects of i.m. alfentanil as premedication for peribulbar block in 90 patients undergoing elective day-case cataract surgery. We compared alfentanil 12.5 micrograms kg-1 injected into the deltoid (n = 30) or gluteal muscle (n = 30) 15 min before the peribulbar block, and placebo (n = 30). The alfentanil concentrations were significantly greater in the d...

BACKGROUND AND OBJECTIVES Currently there is no agreement regarding which one is the most adequate anesthetic technique for the treatment of retinopathy of prematurity. Peribulbar block may reduce the incidence of oculocardiac reflex and postoperative apnea. The goal of this study was to report the outcomes of peribulbar block, when combined with general anesthesia, for the laser treatment for ...

An 80 years old, bronchial asthmatic, male was posted for left cataract extraction with intra ocular lens implantation. He was administered peribulbar block/left facial nerve block. There was no sensory or motor block. Thereafter peribulbar block was repeated. Only partial akinesia was achieved, so under intermittent intra venous sedation, the surgery continued for 40 minutes. In the post-opera...

peribulbar anesthesia is widely applied in cataract surgeries. the aim of this study was comparing the effect of using atracourium, cis-atracourium, and placebo as adjuvant agents to the local anesthetic substance on peribulbar-induced akinesia in cataract surgeries. the study was double-blind randomized clinical trial, among the patients candidate for the cataract surgery who were hospitalized...

PURPOSE To compare the effects of ropivacaine and bupivacaine-lidocaine combination on intraocular pressure, quality of block, and degree of postoperative pain in peribulbar block. METHODS The study group involved 32 patients undergoing elective cataract surgery under peribulbar block. Patients were divided into two groups according to the local anesthetic used: Group 1 (n=16), ropivacaine 0....

BACKGROUND No studies compared parenteral dexmedetomidine with its use as an adjuvant to ophthalmic block. We compared between adding dexmedetomidine to bupivacaine in peribulbar block and intravenous (IV) dexmedetomidine during peribulbar block for cataract surgery. MATERIALS AND METHODS A prospective, randomized, double-blind study on 90 patients for cataract surgery under peribulbar anesth...

The purpose of this study was to evaluate peri-operative outcome after vitreoretinal surgery when peribulbar anaesthesia is combined with general anaesthesia. Sixty adult patients undergoing elective primary retinal detachment surgery with scleral buckling or an encircling procedure received either peribulbar anaesthesia in conjunction with general anaesthesia or general anaesthesia alone. For ...

BACKGROUND/AIMS To devise and evaluate a novel Ocular Anaesthetic Scoring System (OASS) for non-topical local anaesthesia. METHODS In OASS, a score of between 0 (poor) and 14 (excellent) was devised measuring motor (ocular motility, levator and orbicularis function) and sensory functions (digital spear pressure at limbus and topical anaesthetic sting). 40 patients were studied prospectively t...
