Comparison of an extraconal block with a retrobulbar-facial block combination for ocular surgery. A safe alternative technique to the combination of retrobulbar block and facial nerve block.
Four hundred and eight consecutive patients scheduled for cataract surgery under local anaesthesia were randomly allocated to one of two types of regional anaesthesia. One group was given the standard retrobulbar block combined with a facial nerve block of the O'Brien type, and the second group was given a modified peribulbar block. Results indicate that it is possible to achieve a high degree of reliability, within a relatively short time, from the modified peribulbar block without the major complications associated with retrobulbar block.
