A Pain Study Comparing Two Commonly Used Medications to Treat Pain After Bowel Surgery

This research study is testing whether the local anesthetic lidocaine is as effective as ropivacaine for post-operative pain control in continuous thoracic paravertebral nerve blocks. Ropivacaine and Lidocaine are FDA-approved drugs that has been successfully used in this hospital for post-operative pain control for the past few years, thus has become the standard drugs used for this nerve block. Lidocaine has numerous potential advantages over ropivacaine, such as faster onset...

A Difference in Subclavian Vein Catheterization Between Supine and Lateral Tilt Position - Stage I

Central venous catheterization is widely used for various purposes during surgery. For central venous catheterization, subclavian vein is selected because of the relatively low risk of infection, long-term patency and low patient discomfort. The cross - sectional area of the subclavian vein is an important factor to increase success rate. Several studies have reported that the Trendelenburg position increases the cross-sectional area of the subclavian vein, and the lateral tilt...

Noninvasive Pulse Contour Analysis for Hemodynamic Assessment in Patients With Chronic Heart Failure

Determination of hemodynamics plays an important role in the diagnosis of chronic heart failure. The gold standard is intermittent thermodilution via pulmonary artery catheter (PAC). Because of its invasiveness, there are certain risks of this method, e.g. injuries to the nerves and vessels, excessive bleedings, pneumothorax, cardiac arrhythmias etc. Noninvasive pulse contour Analysis (NPCA) is a new method which is able to determine hemodynamics noninvasively via a simple fing...

Plasma Concentration of Lidocaine and Bupivacaine Axillary BPB Mixture Solutions [PCLBAxMix]

The doses of local anesthetics can be decreased with the use of ultrasound guidance. In case of using mixture solutions the benefits and drawbacks are controversial. The plasma concentrations were not studied up to this time in this kind of settings, so investigators believe that this is the first work that shows how lidocaine change the plasma concentration of bupivacaine after axillary approach to brachial plexus employed with different dilute and mixed solutions for upper li...

The investigators conducted a randomized parallel clinical trial with an 8-week follow-up comparing single-use and reused (washed with soap and water, and stored in a container with benzalkonium...

Heart and Skeletal Muscle Problems in Neuroacanthocytosis

The purpose of this study is to learn about heart and skeletal muscle problems related to neuroacanthocytosis (also called Mcleod's syndrome and Levine-Critchley disease). This inherited condition causes problems of blood, brain, heart and muscle function. About 60 percent of patients have an unusual heart muscle abnormality that increases the risk of sudden death. Although the molecular (genetic) changes responsible for neuroacanthocytosis have recently been identified, the...

Lidocaine Reduces Muscle Tremor is Beneficial for Intraoperative Recurrent Laryngeal Nerve Monitoring

In recent years, the application of intraoperative recurrent laryngeal nerve monitoring in thyroid surgery has greatly reduced the complications of recurrent laryngeal nerve injury. The use of intraoperative neurological monitoring requires the reduction of the dose of neuromuscular blockade, which often leads to muscle tremors during the application of electrical energy, which affects the fine separation around the muscles. This study explored the effect of local application o...
