About this study

Hypothesis: During a continuous popliteal nerve block, postoperative analgesia will be improved with the perineural catheter tip at the level of the sciatic nerve bifurcation compared to when the catheter tip is 5 cm cephalad/proximal to the bifurcation.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • undergoing surgery with a popliteal perineural catheter for postoperative analgesia
  • age 18 years or older

Exclusion criteria

  • pregnancy
  • inability to communicate with the investigators and hospital staff
  • incarceration
  • clinical neuropathy in the surgical extremity
  • chronic high-dose opioid use
  • a history of opioid abuse
  • surgery outside of ipsilateral sciatic and saphenous nerve distributions

Treatment and study plan

Catheter Placed At Bifurcation

Procedure

Patients randomized to this group will receive a sciatic nerve block placed at the bifurcaton of the sciatic nerve and outcome measures will be tested.

Catheter Placed 5cm Above Bifurcation

Procedure

Patients randomized to this group will receive a sciatic nerve block placed 5cm above the bifurcaton of the sciatic nerve and outcome measures will be tested.

Primary outcomes

  1. Average Pain

    Time frame: 1 Day following surgery

    The average pain in the three hours previous to a phone call the day following surgery as measured on a numeric rating scale (0-10, 0=no pain, 10=worst imaginable pain).

Secondary outcomes

  1. Analgesic Use

    Time frame: 1 day following surgery

    Total oral opioid use since surgery and total IV analgesics if any.

  2. Sleep Disturbances

    Time frame: 1 day following surgery

    Total number of times patient woke due to pain the night following surgery.

  3. Infusion Side Effects

    Time frame: 1 day following surgery

    Numbness of foot and toes on a 0-10 scale where 0=no numbness and 10=complete numbness.

  4. Satisfaction of pain control

    Time frame: 1 day following surgery

    Patients will give an answer on a 0-10 scale where 0=completely unsatisfied wiht pain control and 10=completely satisfied with pain control.
