Re-evaluation of hyaluronidase in peribulbar anaesthesia.
AIMS/BACKGROUND Hyaluronidase can augment the actions of local anaesthetics in peribulbar anaesthesia. However, evidence suggests satisfactory anaesthesia can be achieved using mixtures without hyaluronidase. A randomised double blind study was conducted on 50 patients, undergoing peribulbar anaesthesia, to validate this observation. METHODS Patients received a standard mixture of local anaes...
متن کاملHyaluronidase and peribulbar block.
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) ...
متن کاملEfficacy of varying concentrations of hyaluronidase in peribulbar anaesthesia.
We have compared the efficacy of adding varying concentrations of hyaluronidase to a standard mixture of 2% lidocaine and 1% ropivacaine to provide peribulbar anaesthesia for cataract surgery. We used (i) the time to adequate anaesthesia for surgery and (ii) ocular and eyelid movement scores at 8 min after block as clinical endpoints. Ninety patients were randomly allocated to receive 7-10 ml o...
متن کاملSafety and Efficacy of Sodium Bicarbonate versus Hyaluronidase in Peribulbar Anaesthesia.
BACKGROUND 400 cases undergoing surgery for cataract under local anaesthesia were studied. Peribulbar anaesthesia involves injecting a mixture of 2% lignocaine, bupivicaine 0.5% and hyaluronidase into the peripheral space of the orbit through a single infero-lateral point. Sodium bicarbonate has been shown to reduce the time of onset of anaesthesia and pain perception when mixed with local anae...
متن کاملHyaluronidase improves regional ophthalmic anaesthesia with etidocaine.
The effect of adding hyaluronidase to regional ophthalmic anaesthesia with etidocaine 1.5% was examined. Two studies were performed in a double-blind fashion. In Study #1, 70 patients were given peribulbar anaesthesia with etidocaine either with or without hyaluronidase (7.5 IU.ml-1) using a standard intraorbital injection and separate lid injections. The block was supplemented as needed. Lower...
