Use of clonidine as a component of the peribulbar block in patients undergoing cataract surgery. Anesth Essays Res ; The chief aims of this pharmacological comparison were to observe the effects on haemodynamic parameters, intraocular pressure IOP changes, duration of analgesia and a possible dose reduction of ropivacaine with the addition of clonidine. Patients were assigned to two groups, ropivacaine group R and ropivacaine clonidine group RCcomprising of patients each, and the randomization sequence were generated using a computerized randomization table kept centrally by a research staff nurse. For all the patients who underwent cataract surgery, a proper record was maintained regarding the demographic characteristics, peribulbar block characteristics and haemodynamic and respiratory parameters.
A retrobulbar block is a simple technique to learn and provides effective anaesthesia Volume to inject ml (dogs), ml (cats/rabbits). Objective To compare the effectiveness of retrobulbar anesthesia (RBA) and peribulbar anesthesia (PBA) in dogs. Animal studied Six adult.
Retrobulbar anesthesia has also been described in dogs (Accola et al. ; Skarda & Tranquilli a; Giuliano ; Hazra et al. ; Dugdale ; Myrna.
Comparative evaluation of ropivacaine and lignocaine with ropivacaine, lignocaine and clonidine combination during peribulbar anaesthesia for phacoemulsification cataract surgery. RegAnesth Pain Med. Ropivacaine was selected for administering peribulbar block on account of its favorable cardiac and neurologic profile as compared with bupivacaine.
Peribulbar anesthesia. Peribulbar block is the most common and safe technique employed worldwide for the operative treatment of cataract, specifically in the phacoemulsification procedure.
Direct vascular effect of ropivacaine in femoral artery and vein of the dog. Background: Peribulbar block is the most common type of local anaesthesia administered for cataract surgery, and continuous efforts are on to find a long-acting. Peribulbar anesthesia for primary vitreoretinal surgery doses of intravenous ropivacaine, bupivacaine, and lidocaine in the conscious dog P.
House, R. Hollands, M. SchulzerChoice of anaesthetic agent for peribulbar anaesthesia.
The motor blockade akinesia was achieved significantly earlier in the RC group at 10 min.
At 3—4-min interval, IOP, HR and MAP returned to the baseline values, which can be possible due to relaxation of the extraocular muscle and, interestingly, these observations also coincided with the onset of sensory analgesia.
The alpha 2-adrenergic agonist clonidine and guanafacine produce tonic and phasic block of conduction in rat sciatic nerve fibres. RESULTS For all the patients who underwent cataract surgery, a proper record was maintained regarding the demographic characteristics, peribulbar block characteristics and haemodynamic and respiratory parameters.
The selection of such a large sample was deliberate to eliminate any other confounding biases.

A double blind comparison of ropivacaine, bupivacaine, and mepivacaine during sciatic and femoral nerve blockade. Thereafter, no significant difference could be recorded statistically in both the groups regarding the rate of fall of IOP. All the patients were discharged on the next morning of surgery. A significant statistical difference was observed at 15—20 min, and the difference remained the same during the rest of the surgical and recovery period.

Peribulbar block is the most common and safe technique employed worldwide for the operative treatment of cataract, specifically in the phacoemulsification procedure.
Surgery in this population group is always challenging and is associated with various risks, whether it is performed under general anaesthesia or regional anaesthesia.
Conclusions: Addition of clonidine to ropivacaine not only decreases the total volume of LA to be used but also augments early onset and prolonged offset of sensory analgesia as well as provides smooth operating conditions with a good sedation level as well by providing a wider safety margin of LA. The onset of sensory anaesthesia was much earlier 3. Regional anaesthesia has gained massive popularity for day care phacoemulsification cataract surgery as it avoids complications and untoward events associated with general anaesthesia.
Objectives: A double-blind, prospective and randomized study was carried out in our institute to compare the anaesthetic effects of ropivacaine with the combination of ropivacaine and clonidine in administration of peribulbar block for phacoemulsification cataract surgery.
