When anesthesiologists perform a regional nerve block, they will often put a catheter - a flexible plastic tube - in the patient to allow for continuous delivery of local anesthetic. This allows the nerve(s) to be 'frozen' so that the patient is more comfortable during and after surgery. The most common method of placing the catheter close to a nerve involves threading the catheter through a needle which has been inserted under the skin. Because the catheter is very thin and flexible, it does not thread well through tissue and will buckle and kink when enough force is applied to it. Another problem is that the puncture hole left by the needle is larger than the diameter of the catheter, meaning that when the needle is withdrawn, the catheter is not secure, which increases the chance that it will dislodge and cause leakage of local anesthetic. One solution to these problems is to use a catheter placement method similar to how intravenous catheters are installed. In this method, the catheter fits around ('over') the needle, which results in more support for the catheter while it is being pushed under the skin. We wish to examine if a catheter-over-needle method would be useful for placing a catheter to deliver local anesthetic during peripheral nerve blockade. We will compare the catheter-over-needle method to the currently used catheter-through-needle method on patients who require continuous anesthetic delivery for their surgery; half the patients will receive anesthetic through one method, and the other half will receive anesthetic through the other method. We believe that using the catheter-over-needle method will result in more secure placement of the catheter and more efficient delivery of local anesthetic.
Central venous catheters are needed in the critical care setting to administer drugs. Three sites are available to gain vascular access: subclavian, internal jugular and femoral. Each site has complications, but there is no randomized controlled study which compared the 3 sites. The investigators hypothesis is that subclavian catheterization reduces the risk of major complications compared to internal jugular or femoral.
Traditional teaching that suggests the ipsilateral nipple as the directional guide for needle advancement during Internal Jugular Vein (IJV) catheterization has weak grounds. The investigators attempt to validate this long-standing statement.
TegaCHG is a multicentric randomized study aimed at evaluating the possibility that the use of TegaDerm CHG dressing may reduce the incidence of catheter related blood stream infections (CRBSI). It implies the comparison between the incidence of CRBSI in patients with central venous catheter dressed with TegaDerm without chlorhexidine gluconate (CHG) and with CHG. The primary endpoint is the occurrence of CRBSI and the secondary endpoints are: catheter colonization (growth of microbes from the culture of catheter tip, > 15 CFU according to semi-quantitative method or > 1000 CFU according to quantitative method); incidence of catheter exit site infection; occurrence of catheter related infections/sepsis or other severe infection-related complications; safety profile evaluation: occurrence of hypersensitivity to the dressing on the basis of local objectivity (erythema, edema, other) or on that of patient symptoms (itch, burning sensation); relating to the device performance: incidence of high/medium/low dressing edge lift, ability to visualize the catheter insertion site, easiness of removal, easiness of dressing application; incidence of unscheduled dressing change. The study hypothesis implies that the use of slow release device containing chlorhexidine may decrease the incidence of CRBSI. This has already been showed for chlorhexidine impregnated sponges. Scope of the study is to verify if this property is also true for TegaDerm CHG,which is a new chlorhexidine-releasing dressing in which the medication is directly released by an integrated transparent gel pad, so that the catheter exit site remains visible and easy to inspect without removing the dressing.
Children fear having an intravenous (IV) needle placed because of the pain that they will experience. The more needle punctures that a child has to endure before the IV is successfully placed, the greater the pain experienced and anxiety suffered. In addition, false starts increase the demands on medical staff and can increase the length of the emergency department stay. Often, veins are difficult to see or feel, particularly in an unwell, dehydrated child or in young infants who have more fat below the skin surface. Also, the venous pattern below the skin surface naturally varies from person to person and therefore success in placing IVs leaves room for improvement. Technology may be able to play an important role is improving the rates of success. The investigators wish to investigate whether the use of either an Ultrasound machine or a VeinViewer machine can improve the rate of success of the initial attempt (skin puncture) at peripheral IV placement in comparison to the current standard approach.
The objective of this study is to evaluate the effectiveness of Accuvein to facilitate venous blood sampling and placement of peripheral intravenous catheters in adults. This clinical protocol is designed to determine whether using Accuvein increases the ease and efficiency of venous cannulation (as perceived by the operator), decreases the time to effective cannulation, decreases the number of sticks, and decreases the patient's perception of the pain.
The aim of this study is to evaluate the optimization of local anesthetic effect with duplex ultrasound-guided injection of lidocaine before femoral artery puncture during diagnostic or therapeutic interventional procedures. In total, 200 patients scheduled for various diagnostic or therapeutic interventional radiology procedures requiring femoral artery puncture, will be randomized in two groups after informed consent. Patients will be randomized to undergo groin local anesthesia with the proposed method of duplex ultrasound guided injection of lidocaine versus standard injection of lidocaine with manual palpation (control group). The protocol includes the registration of patients' demographics (age, gender, risk factors for peripheral arterial disease), arterial morphological characteristics (calcifications and presence of atheromatous disease), as well as technical details of the procedure (total puncture duration, sheath size, antegrade/retrograde puncture, etc.) Primary study endpoint will be peri-procedural pain that will be assessed with the use of a visual analog scale (VAS) completed by the patient at the end of the procedure. Secondary study endpoints will evaluate procedural safety and complications during the immediate post-procedural period (up to 7 days).
The purpose of this study is to evaluate healthy volunteers perception of catheterization with LoFric catheters with new solvents in the manufacturing process. The subjects will be catheterized three times during one visit day. The hypothesis is that the subjects' perception of catheterization is the same when using the test catheters compared to the reference catheter.
A study comparing a 10 cm catheter with a 7 cm catheter in a group of female patients who, on a routine bases, empty their bladder using urinary catheters, by measuring residual urine after intermittent catheterization.
