Study Arms (2)

Placebo Group (TAP-S)

PLACEBO COMPARATOR

(TAP-S) - the On-Q reservoir will be filled with saline and set to infuse at rate of 10 ml/hr through the TAP catheter

Drug: TAP-S

Active Group (TAP-C)

ACTIVE COMPARATOR

(TAP-C) - The On-Q reservoir will be filled with 0.2% ropivacaine and set to infuse at rate of 10 ml/hr through the TAP catheter

Device: TAP-C

Interventions

TAP-CDEVICE

TAP catheters with ropivacaine infusion are inserted into the TAP area after a single shot TAP block. Single shot TAP block is performed using 30ml 0.5% ropivacaine at the end of the case.

Also known as: Continuous TAP catheter
Active Group (TAP-C)
TAP-SDRUG

Catheters with saline infusion are inserted into the TAP area after a single shot TAP block. Single shot TAP block is performed using 30ml 0.5% ropivacaine at the end of the case.

Also known as: Single shot TAP block

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy subject undergoing laparoscopic live donor nephrectomy
  • (ASA) American Society of Anesthesiologists class 1 or 2
  • Age 18 or older, male or female
  • Desires TAP block for postoperative pain control

You may not qualify if:

  • Any contraindication for TAP block - single or continuous
  • History of substance abuse
  • Any physical, mental or medical conditions which, in the opinion of the investigators, may confound quantifying postoperative pain resulting from surgery.
