Abstract:
One hundred elderly men (> or =65 yr) undergoing transurethral procedures (<45 min) received bupivacaine 7.5 mg, or bupivacaine 5 mg + fentanyl 20 mug, or bupivacaine 4 mg + fentanyl 20 mug, or bupivacaine 3 mg + fentanyl 20 mug, 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 mug provided adequate analgesia and was associated with hemodynamic stability and a favorable recovery profile.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
