Summary

The purpose of this research study is to evaluate the analgesic efficacy of adding a single shot parasacral (sciatic) nerve block to a continuous lumbar plexus block in patients undergoing total hip replacement.

Detailed description

This prospective study is intended to assess the efficacy of placing a parasacral (sciatic) nerve block in addition to a lumbar plexus block for postoperative analgesia following total hip arthroplasty. Although the placement of a lumbar plexus block alone has become accepted as the standard of care at UPMC for postoperative analgesia following total hip arthroplasty, the addition of a parasacral (sciatic) nerve block may provide the advantage of blocking the superior gluteal nerve and nerve to the quadratus femoris which both supply small articular sensory branches to the posterior hip capsule.

Conditions

• Osteoarthritis of Hip
• Regional Anesthesia
• Other Acute Postoperative Pain
• Total Hip Arthroplasty
• Peripheral Nerve Block
• Lumbar Plexus Nerve Block
• Parasacaral (Sciatic) Nerve Block

Interventions

Type	Name	Description
PROCEDURE	Continuous Lumbar Plexus Block	Lumbar plexus nerve block placement and activation: After subcutaneous infiltration of local anesthetic, 20 mL of Ropivacaine 0.2% will be injected; the catheter will be introduced for 5 cm past the needle tip and secured with steri strips and tegaderm. In PACU, the catheter will be connected to a pump of 0.0625% bupivacaine at 5 - 10 mL per hour at the discretion of the Acute Interventional Perioperative Pain Service (AIPPS). Additional 5mL boluses of 0.0625% bupivacaine will be given on demand once per hour prn.
PROCEDURE	Parasacral Nerve Block	A single shot parasacral (sciatic) nerve block will then be place under the ultrasound guidance. Ropivacaine 0.2% 9 ml will be injected.
DRUG	Ropivacine 0.2%	Lumbar plexus nerve block placement and activation: After subcutaneous infiltration of local anesthetic, 20 mL of Ropivacaine 0.2% will be injected; the catheter will be introduced for 5 cm past the needle tip and secured with steri strips and tegaderm.
DRUG	Bupivacaine 0.0625%	In PACU, the catheter will be connected to a pump of 0.0625% bupivacaine at 5 - 10 mL per hour at the discretion of the Acute Interventional Perioperative Pain Service (AIPPS). Additional 5mL boluses of 0.0625% bupivacaine will be given on demand once per hour prn.
