Retrobulbar block using pentothal as a sedative for ambulatory cataract surgery

Cataract surgery comprises 80% to 85% of the surgical procedures performed at our ambulatory surgical center. We have developed a safe and effective method of sedation and amnesia for performing a retrobulbar block. We use sodium thiopental, administered intravenously, just prior to the block. We encourage the anesthesia departments of other facilities to consider this relatively simple blocking procedure for the comfort and safety of the patient.
