NCT ID: NCT06309381 Recruiting - Foot Surgery Clinical Trials

Influence of Sensory Block Duration on Rebound Pain After Outpatient Foot Surgery Under Popliteal Sciatic Nerve Block.

Start date: February 8, 2023
Phase:
Study type: Observational

Rebound pain after surgeries under peripheral nerve block is defined as the appearance of severe acute postoperative pain after regression of the sensory block. The incidence of this condition can reach up to 40-50% in patients undergoing ambulatory surgeries. Rebound pain represents a clinically significant issue that may outweigh the benefits of regional anaesthesia. This is particularly significant for painful outpatient surgeries, where inadequately managed pain can result in distress, potentially affecting patient satisfaction and recovery. It may also lead to unplanned utilization of healthcare resources or readmissions. Orthopaedic foot surgery is a prevalent outpatient surgery, potentially painful, where rebound may be a difficult challenge. However, to date, prospective studies focusing specifically on rebound pain in outpatient foot surgery are limited. Identifying conditions associated with rebound pain or at-risk patients could facilitate the development of preventive and treatment strategies, thereby enhancing pain management or relief. Younger age, female sex and bone surgery are non-modifiable factors associated with severe rebound pain. Perioperative intravenous dexamethasone has been identified as a modifiable independent risk factor associated with a reduced incidence of rebound pain. Regarding anaesthetic factors, the duration of the peripheral block has been proposed as a potentially modifiable factor influencing rebound pain; however, current evidence does not support this hypothesis. The goal of this prospective observational study is to evaluate the incidence of rebound pain specifically in outpatient orthopaedic foot surgery involving bone under popliteal sciatic nerve block and to assess the possible association between sensory block duration and the incidence of rebound pain.

Mepivacaine Versus Bupivacaine Onset Time in Ultrasound-guided Ankle Blocks

Start date: March 11, 2024
Phase: Phase 4
Study type: Interventional

The purpose of this research is to determine if both local anesthetics (mepivacaine and bupivacaine) are similar in their onset of sensory block to assess the efficiency of ultrasound-guided ankle blocks in our practice. Currently it is the standard of care to perform ankles blocks with both mepivacaine and bupivacaine. However, given similarity in their safety profile researchers would like to compare if one is non-inferior to the other in terms of onset time of ankle block.

MIDCAB (Mid-Calf Block) for Foot Surgery

MIDCAB
Start date: July 21, 2022
Phase: Phase 4
Study type: Interventional

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.

Effect of Ropivacaine During Popliteal Nerve Block in Foot and Ankle Surgery

Start date: August 31, 2017
Phase: Phase 3
Study type: Interventional

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.

Study type: Observational

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.
