Randomized Controlled Trial Comparative Study Clinical TrialRetrobulbar 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.

Randomized Controlled Trial Clinical TrialEffects of retrobulbar bupivacaine on post-operative pain and nausea in retinal detachment surgery.
A prospective double-masked clinical trial was conducted to determine whether retrobulbar bupivacaine block had an effect on post-operative pain, nausea and intra- and post-operative use of analgesics in retinal detachment surgery performed under general anaesthesia. Thirty-two patients were randomized to have general anaesthesia with or without retrobulbar bupivacaine. Pain score was documented as 0-10 (0 = no pain. 10 = worst pain ever felt). ⋯ Men complained more about post-operative pain than did women. The patients in the retrobulbar group complained less about nausea. Significantly fewer patients in the retrobulbar group required parenteral pain relief during operation and the first 48 h after.
