Study Details

Study Description

Brief Summary

It is aimed in this study to compare the effect of using local anaesthetics in a higher volume and lower dose on the total anesthetic consumption and quality of labor analgesia with dural puncture epidural technique.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Group I: Lower Volume with Higher Anaesthetic Concentration
  • Procedure: Group II: Higher Volume with LowerAnaesthetic Concentration
N/A

Detailed Description

This study will be conducted as a prospective randomized, controlled, double-blind trial following the approval of the ethical committee at Atatürk University Medical Faculty Hospital and after obtaining written consent from the participating patients. The study will include pregnant women aged 20 to 45 with American Society of Anesthesiologists (ASA) II classification, full-term, nulliparous and singleton pregnancies. Using a randomisation procedure, the participants will be allocated into two equal groups: Group I and Group II.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: 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.

Procedure: 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

Active Comparator: 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.

Procedure: 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

Outcome Measures

Primary Outcome Measures

  1. Difference between total local anaesthetic consumption [5 hours or before if the labor is completed]

    The study will involve monitoring the patients starting 2 minutes after the initial epidural dose, every 2 minutes during the first 20 minutes. Monitoring will continue at the 30th minute, and once in every 90 minutes for 5 hours or until labor is completed. Total bupivacain consumption will be calculated as follows: PIEB + PCEA + boluses by the clinician. Bupivacain consumption per hour will be calculated.
