Bupivacaine anesthesia in retinal detachment surgery
T. L. Holekamp, N. P. Arribas and I. Boniuk
Retinal detachment surgery and other long-duration ocular procedures can be
performed safely with local anesthesia, but a long-acting anesthetic is
required. A randomized and masked prospective series of 126 scleral
buckling procedures was undertaken to test a mixture of bupivacaine
(Marcaine), lidocaine (Xylocaine), and epinephrine against lidocaine and
epinephrine. The data collected show a conclusive superiority of the
bupivacaine mixture in longevity of action and overall performance. Also,
there was significantly less variability in the quality of anesthesia with
the mixture than with lidocaine (p = .0015).
