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.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Supportive Care

Adductor canal (AC) nerve block is a commonly used modality for postoperative pain control after total knee arthroplasty (TKA). When the adductor canal is viewed by ultrasound, the femoral...
The purpose of this study is to determine which technique for catheter placement in continuous femoral nerve block (FNB) is most successful - guidance with (1) ultrasound or (2) nerve stim...
1. Interscalene continuous catheter is a very effective way of controlling pain in total shoulder arthroplasty. To ensure proper placement, nerve stimulating catheter is quite o...
The investigators' objective is to evaluate whether any of the various peripheral nerve block catheter dressing strategies currently employed by the Boston Children's Hospital Regional Ane...
This is a randomized study which will compare three femoral nerve catheter insertion techniques. Subjects will be randomized into one of thee groups, Group 1: ultrasound guided femoral ne...
The volume-duration relationship using low concentrations of ropivacaine for peripheral nerve blocks is unknown, even though low concentrations of ropivacaine are increasingly used clinically. We inve...
This study was performed to compare the efficacy and comfort of the inferior alveolar nerve (IAN) block and the Vazirani-Akinosi (VA) nerve block when administered by dental trainees.
Freehand ventricular catheter placement has been reported to have poor accuracy.
Central venous catheter (CVC) placement, particularly in emergency setting, may be associated with significant morbidity and mortality.
Fascia iliaca block or femoral nerve block is used frequently in hip fracture patients because of their opioid-sparing effects and reduction in opioid-related adverse effects. A recent anatomical stud...
Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.
Infections resulting from the use of catheters. Proper aseptic technique, site of catheter placement, material composition, and virulence of the organism are all factors that can influence possible infection.
Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
