The Postoperative Analgesic Efficacy of Varied Concentrations of Ropivacaine Used for the Transverse Abdominis Plane (TAP) Block After Cesarean Delivery
In Brief
A Phase 4 clinical trial evaluating 0.9% Normal Saline, 0.2% Ropivacaine, and 2 other interventions for Postoperative Pain and 2 related conditions. Completed, enrolled 120 participants across 1 site.
Detailed Summary
Since there have been no published dose-response studies investigating the effective analgesic dose of ropivacaine for use in a TAP block for post-Cesarean delivery analgesia, the investigators propose a study primarily examining the effect on 24 hour post-Cesarean delivery opioid consumption of using either a placebo, 0.25% ropivacaine, 0.5% ropivacaine, or 0.75% ropivacaine for TAP blocks.
Study Details
Timeline
Interventions
The abdominal muscle layers will be located by placing the ultrasound transducer perpendicular to the coronal anatomic plane at the T-10 dermatome level in the patient's midaxillary line. Under ultrasound guidance, a 70mm or 90mm, 21 gauge blunted Stimuplex needle will be advanced from the skin until the tip reaches the fascial layer between the internal oblique and transversus abdominis. 15ml of the study drug will be injected incrementally. The needle will then be removed and the process repeated in the same manner on the patient's opposite side.
