b. Intrathecal anesthesia for elderly patients undergoing short transurethral procedures: a dose‑finding

Answer 1

Hyy?? what's that question means?

Answer 2

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.
