 The technique for epidural placement and dosing will be standardized as follows. Epidural dosing will consist of 5 mL of 0.125 bupivicane with 10 mcgmL of fentanyl. This standard bolus dose will be administered and levels of sensory block and numeric patient pain scores will be recorded. If patients have not achieved a pain score of 4 or less at 15 minutes after the epidural bolus, an additional bolus will be administered to achieve appropriate pain control. The volume of additional epidural bolus will be recorded.
