Local Anesthetic Delivery Methods for Postoperative Pain
What You Need to Know Before You Apply
What is the purpose of this trial?
This will be a randomized comparison of continuous local anesthetic infusion with patient controlled boluses (PCA) to patient-titratable automated boluses with patient controlled boluses (PCA) for both infraclavicular and popliteal-sciatic perineural catheters. The overall goal is to determine the relationship between method of local anesthetic administration (continuous with PCA vs. titratable intermittent dosing with PCA) for these two perineural catheter locations and the resulting pain control. The investigators hypothesize that, compared with a traditional fixed, continuous basal infusion initiated prior to discharge, perineural local anesthetic administered with titratable automated boluses at a lower dose and a 5-hour delay following discharge will (1) provide at least noninferior analgesia during the period that both techniques are functioning; and, (2) will result in a longer overall duration of administration \[dual primary end points\].
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, if you use opioids daily, you cannot participate in the trial.
Is ropivacaine 0.2% safe for use in humans?
Ropivacaine is generally considered safe for use in humans, with a lower risk of heart-related side effects compared to similar drugs like bupivacaine. However, there have been a few reports of central nervous system side effects, especially at higher concentrations or if accidentally injected into a blood vessel.12345

Are You a Good Fit for This Trial?
This trial is for patients having certain arm or foot/ankle surgeries who will receive a catheter for pain relief after surgery. It's not for those who've used opioids daily in the past month, are pregnant, have nerve/muscle issues in the affected limbs, are incarcerated, had additional surgeries outside of specific areas, or are morbidly obese.Inclusion Criteria
