Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group I
The patients will be given 10 ml of a solution containing 0,1% of bupivacaine and 2 mcg/ml fentanyl through the epidural cathether. Level of sensory block will be tested by testing with ice from S2 dermatome cephally.
Analgesia will be maintained by programmed intermittant epidural (PIE) boluses of 7,5 ml of the same solution once in every hour, starting 1 hour after the loading dose. In addition, patient controlled epidural analgesia (PCEA) will be programmed so that 8 ml of the same solution with a lock-time of 10 ml may be administered. "Breakthrough pain" that requires even further analgesia will be treated with an epidural bolus of 5 ml of 0,125% bupivacain solution.
Group I: Lower Volume with Higher Anaesthetic Concentration
10 ml of a solution containing 0,1% of bupivacaine and 2 mcg/ml fentanyl through the epidural cathether, maintained by programmed intermittant epidural (PIE) boluses of 7,5 ml of the same solution once in every hour, starting 1 hour after the loading dose. patient controlled epidural analgesia (PCEA) will be programmed so that 8 ml of the same solution with a lock-time of 10 ml may be administered
Group II
The patients will be given 20 ml of a solution containing 0,0625% of bupivacaine and 2 mcg/ml fentanyl through the epidural cathether. Analgesia will be maintained by programmed intermittant epidural boluses of 15 ml of the same solution once in every hour, starting 1 hour after the loading dose. In addition, patient controlled epidural analgesia (PCEA) will be programmed so that 8 ml of the same solution with a lock-time of 10 ml may be administered. "Breakthrough pain" that requires even further analgesia will be treated with an epidural bolus of 5 ml of 0,125% bupivacain solution.
Group II: Higher Volume with LowerAnaesthetic Concentration
20 ml of a solution containing 0,0625% of bupivacaine and 2 mcg/ml fentanyl through the epidural cathether, maintained by programmed intermittant epidural boluses of 15 ml of the same solution once in every hour, starting 1 hour after the loading dose. patient controlled epidural analgesia (PCEA) will be programmed so that 8 ml of the same solution with a lock-time of 10 ml may be administered
