4 Clinical Trials for Various Conditions
Pregnant women with a history of opioid use disorder, chronic opioid use or those who are on medication assisted treatment will be randomly assigned to receive either a sub-fascial continuous infusion of bupivacaine or lidocaine/menthol patch after Cesarean delivery. Post-operative pain scores and opioid usage in the post-operative period will be recorded.
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 \[dual primary end points\].
Rib fractures represent a common injury pattern this is highly associated with patient morbidity and mortality, as pain control remains a challenge. Even after surgical stabilization of rib fractures (SSRF), unsuccessful pain control can lead to morbid outcomes such as pneumonia and opioid dependence. Multi-modal anesthesia, with the use of thoracic epidurals and para-vertebral injections/catheters, has shown to lessen these occurrences but are subject to a wide array of limitations. A more directed therapy with liposomal bupivacaine has shown to provide sustained analgesia for up to 72 hours in patients who have undergone other types of thoracic surgery, but not SSRF. The hypothesis of the current clinical trial is that, among patients undergoing SSRF, liposomal bupivacaine delivered via video assisted thoracic surgery (VATS) is an intercostal nerve block that provides comparable analgesia to the pain catheter, as measured by pulmonary function, numeric pain scoring, and postoperative narcotic use.
The investigators propose a prospective blinded randomized control trial (RCT) to assess the efficacy and safety of a simple method of continuous infusion of a local anesthetic, ropivacaine, via a surgical wound to control pain after ureteropelvic junction (UPJ) stenosis correction in children during the first 48 hrs after surgery. The investigators hypothesize that this technique will provide greater pain relief post-operatively and reduce the need for systemic opioid use along with a reduction in associated side effects of such analgesics.
