Transversus Abdominis Plane (TAP) Block for Post Caesarian Pain (TAPBlock)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01986049
Recruitment Status : Completed
First Posted : November 18, 2013
Last Update Posted : April 6, 2018

Brief Summary:
Adding TAP block with Bupivacaine may decrease the use of PCA bolus use after caesarean section for pain relief.

Condition or disease Intervention/treatment Phase
Obstetrical Complications From Sedation During Parturition Drug: Bupivicaine Phase 3

Detailed Description:

Participants in the study will be randomized to TAP block with 0.5% or 0.25% bupivacaine or with placebo (normal saline).

The number of PCA bolus used within 24 hours post cesarean section will be compared between the groups.

Primary Outcome Measures :
  1. Transversus Abdominis Plane (TAP) Block for Post Caesarean Pain [ Time Frame: The first post operative 24 hours ]
    In Patient Controlled analgesia (PCA) system, the patient receives a preset dose of morphine by pressing a button on a computerized pump that is connected to an IV catheter. With PCA the patient may receive a small continuous flow of morphine and add more morphine as needed to provide a more constant level of comfort. In this study, we will compare the number of PCAs used by the participants in each arm

Secondary Outcome Measures :
  1. Decrease in the pain score as measured by Visual Analog Scale (VAS) [ Time Frame: The first post operative 24 hours ]
    Visual Analog Scale (VAS) is a numeric scale to measure the pain intensity from 0 to 10, where 0 = no pain, (1-3) = mild pain, (4-6) = moderate pain, and (7-10) = severe pain. The worst imaginable pain = 10
