Summary

This is a research study to determine if the concentration of local anesthetic through a catheter next to the nerves that go to the hip that is undergoing surgery, affects muscle strength and sense of touch experienced after surgery. This study is looking at the varying concentrations of local anesthetic placed through the catheter.

Conditions

  • Hip Arthroplasty
  • Hip Pain

Interventions

DRUG

0.1% Ropivacaine

Ropivacaine 0.1% will be administered via the perineural catheter as follows: Basal Rate (12mL/h); Basal Dose (12 mg/h); Bolus Volume (4 mL); Bolus Dose (4 mg); Lockout Duration (30 min); Maximum Dose (20 mg/h)

DRUG

0.4% Ropivacaine

Ropivacaine 0.1% will be administered via the perineural catheter as follows: Basal Rate (3 mL/h); Basal Dose (12 mg/h); Bolus Volume (1 mL); Bolus Dose (4 mg); Lockout Duration (30 min); Maximum Dose (20 mg/h)
