One hundred elderly men (65 yr) undergoing transurethral procedures (<45 min) received bupivacaine 7.5 mg, or bupivacaine 5 mg + fentanyl 20 µg, or bupivacaine 4 mg + fentanyl 20 µg, or bupivacaine 3 mg + fentanyl 20 µg, intrathecally. Intraoperative "rescue" fentanyl requirements were higher (P < 0.03) in group bupivacaine 3 mg + fentanyl. Times (min) to ambulation eligibility were decreased in a dose-dependant manner (157 ± 50 vs 147 ± 37 vs 128 ± 40 vs 116 ± 29, respectively). Of the techniques studied, intrathecal bupivacaine 4 mg + fentanyl 20 µg provided adequate analgesia and was associated with hemodynamic stability and a favorable recovery profile.
