Retrobulbar anaesthesia. A clinical evaluation of four different anaesthetic mixtures.

One-hundred and thirty-nine consecutive cases of retrobulbar blocks were evaluated concerning clinical effect on motility and pain. The patients were randomly selected to one of four different mixtures of anaesthetics. A mixture containing lidocaine w/adrenaline, bupivacaine w/adrenaline and hyaluronidase was shown to be significantly more effective than any of the other tested mixtures concerning analgesia and significantly better than mixtures without hyaluronidase concerning motility/akinesia.
