Transversus Abdominis Plane (TAP) Blocks With Ropivacaine Continuous Infusion Catheters vs Single Dose Liposomal Bupivicaine: A Prospective Randomized Control Trial for Pain Control After Renal Transplant Surgery
University of California, Davis
Summary
This study is a comparison of the analgesic efficacy of transversus abdominis plane (TAP) blocks with ropivacaine bolus plus continuous ropivacaine infusion via catheters versus single shot TAP blocks with liposomal bupivacaine.
Description
This study is a comparison of the analgesic efficacy of TAP blocks provided by ropivacaine bolus plus continuous ropivacaine infusion via catheters versus single shot TAP blocks with liposomal bupivacaine. In the Liposomal Bupivacaine group, TAP block will be performed using ultrasound guidance. 12ml of 0,25% plain bupivacaine will be used for skin infiltration and to open up the TAP. Liposomal Bupivacaine 266 mg (1.3% in 20 ml) will be diluted to 40 ml volume with 20 ml of preservative free normal saline. 20 ml (133mg) of liposomal bupivicaine will then be injected into the TAP. For those r…

Interventions
- DrugRopivacaine Continuous Infusion Catheter
For those randomized to the TAP catheter group, ultrasound guidance will be used for TAP block and 5mls 1% lidocaine will be used for skin infiltration. A peripheral nerve catheter will be placed approximately 3-5 cm into the TAP space after injection of the ropivacaine solution. A bolus dose of 2.5 mg/kg of ropivacaine will be administered in a volume of 30 ml up to a maximum of 150 mg. An infusion with a programmable pump will be initiated at a rate of 8 ml/hr of 0.2% ropivacaine on the inpatient floor.
- DrugSingle Dose Liposomal Bupivicaine
TAP block will be performed using ultrasound guidance. 12ml of 0,25% plain bupivacaine will be used for skin infiltration and to open up the TAP. Liposomal bupivacaine 266 mg (1.3% in 20 ml) will be diluted to 40 ml volume with 20 ml of preservative free normal saline. 20 ml (133mg) of liposomal bupivicaine will then be injected into the TAP.
