Filter by:This study aims to understand the ideal formulation to utilize in saphenous nerve and popliteal nerve blocks for foot and ankle procedures. It will examine the use of liposomal bupivacaine alone or liposomal bupivacaine with dexamethasone prior to foot and ankle procedures in peripheral nerve blocks. We will compare liposomal bupivacaine (Exparel) and liposomal bupivacaine (Exparel) combined with dexamethasone to determine if the addition of dexamethasone significantly decreases postoperative narcotic use and prolongs analgesic effects when administered in a popliteal and saphenous block prior to foot and ankle orthopedic procedures.
MIDCAB is defined as a group of ultrasound guided distal nerve blocks at the level of the individual branches. It is similar to an Ultrasound Guided (USG) Ankle block but the probe is placed higher on the calf covering all and any surgery of the foot and ankle, providing prolonged analgesia since we are blocking the individual nerves and preserving the proximal motor function. This study is determining the potential therapeutic effect of MIDCAB during the hospital stay and recovery period in patients undergoing foot/ankle surgeries that require spinal anesthetic and peripheral nerve blocks. A total of 20 patients at HSS will participate to see if MIDCAB is not only effective at providing analgesia (pain relief) but to see if it allows allows patients to maintain motor function (movement) of the foot and ankle unlike the current popliteal block which is done above the knee and prevents patients from moving their foot. During the course of the study we will also be looking at patients numeric pain scores with movement and at rest along with post-operative nausea and vomiting, the presence of numbness and it patients can move their foot. Along with all of these, the study will also look at the amount of opioid pain medications taken by patients along with medication-related side effects. As a result, the study will be used to determine if MIDCAB provides analgesia for patients undergoing foot/ankle surgery while allowing them to maintain movement of the foot. This pilot study will also be used to gather preliminary data that will allow us to perform a power analysis for a subsequent randomized clinical control trial that would compare the MIDCAB block to the popliteal block.
This is a retrospective chart review to determine the non-inferiority of performing lower extremity peripheral nerve block placement under spinal anesthesia compared to its pre-spinal counterpart.
With the increasing rise of outpatient surgery in orthopaedic procedures, the management of immediate postoperative pain has been a major topic investigated, with the use of a peripheral nerve block in combination with general anesthesia being a commonly accepted method. Foot and ankle procedures, which offer the choice of several anesthetic techniques, have increasingly been performed with this method predominantly through the combination of general anesthesia with a single-injection popliteal nerve block to reduce the substantial acute postoperative pain that often requires large opioid intake within the post-anesthesia care unit (PACU). However, as a single-injection peripheral nerve block resolves off shortly following surgery, major postoperative pain, termed "rebound pain", can also arise, and has the potential to be even greater than that of patients who do not receive any peripheral nerve block with general anesthesia. The purpose of this study is to evaluate the contribution of ropivacaine concentration (0.5% versus 0.25%) of the initial bolus in continuous popliteal nerve blocks toward the rebound pain phenomena, or the quantifiable difference in pain experienced during the initial time after block resolution, in foot and ankle surgeries.
This study aims to determine the effectiveness and safety of two standard of care perioperative procedures for controlling pain following ankle and hindfoot osteotomy or fusion or ankle fracture repair.
The automated TALAS measurement tool, working with the Cone Beam 3D scanner under load, provides a reproducible measurement of the Foot Ankle Offset (FAO). It is possible to determine an average value and the standard deviation of FAO in the relevant population. And to differentiate significantly the populations with a neutral alignment, varus or valgus.
Researchers are trying to determine if a high ankle block during ankle surgery provides the same pain relief as the standard regional block.
Research study to determine the relationship between perineural catheter tip location relative to the sciatic nerve bifurcation and postoperative analgesia for continuous popliteal nerve blocks.
Hypothesis: When performed under ultrasound guidance, there is improvement in the sensory and motor blockade obtained with stimulating popliteal catheters versus those placed without nerve stimulation.
