Addition of hyaluronidase to lignocaine with adrenaline for retrobulbar anaesthesia in the surgery of senile cataract.
نویسنده
چکیده
A double-blind trial demonstrates the effectiveness of adding hyaluronidase to lignocaine with adrenaline in producing ocular akinesia and anaesthesia in retrobulbar nerve blocks. 92% of the blocks in which hyaluronidase was used for intracapsular cataract surgery were judged successful compared with 56% of those without added hyaluronidase (p less than 0.01).

Extracapsular cataract extraction under local anaesthesia without retrobulbar injection.
Day-case cataract surgery and the need for local anaesthesia are likely to increase. Retrobulbar (and peribulbar) anaesthetic injection is a common technique in cataract surgery, but serious complications are persistently reported. Subconjunctival injection is an alternative that avoids these risks. This retrospective study compares two groups of patients that underwent extracapsular cataract s...

Aims—A prospective, randomised, double blind study was used to investigate the eVect of hyaluronidase on the quality of block achieved with sub-Tenon’s local anaesthesia. Methods—150 patients scheduled for elective cataract surgery were randomly allocated to either sub-Tenon’s block with 3 ml lignocaine 2%/adrenaline 1:200 000 alone or with the addition of 30 IU/ml of hyaluronidase. The blocks ...

Two methods of periocular anaesthesia (PI and PII) were compared with the traditional retrobulbar block in a prospective study of 450 patients undergoing elective cataract extraction and intraocular lens implantation. A solution of local anaesthetic containing equal amounts of 2% lignocaine and 0.5% bupivacaine was used in all the groups. Hyaluronidase (75 IU/10 ml of local anaesthetic solution...
