Randomized Controlled Trial Comparative Study
A controlled clinical interventional trial comparing 2% chloroprocaine-bupivicaine versus 2% lidocaine-bupivicaine for retrobulbar anesthesia in scleral buckling surgery.
We undertook this prospective study to compare the relative effectiveness of a bupivicaine mixture with either lidocaine or chloroprocaine for retrobulbar anesthesia in scleral buckling surgery, since chloroprocaine, in some types of nonocular nerve block anesthesia, has been demonstrated to be a more effective nerve block anesthetic. ⋯ We found no difference in effectiveness for bupivicaine mixed with either lidocaine or chloroprocaine for retrobulbar anesthesia in scleral buckling surgery. Surgeon, anesthetist, and patient-centered data showed no differences in any of the measures studied.

To determine whether the implementation of Routine Notification and Request (RNR) has been effective in increasing the amount of donor corneal tissue available and reducing wait times for corneal transplant (CT) surgeries. ⋯ RNR has been effective in increasing corneal tissue availability and decreasing wait times in provinces where it has been implemented. We recommend similar legislative changes to be considered in those provinces where corneal tissue shortage is delaying the availability of CT surgery.
