Filter by:The central venous catheter (CVC) has been used for the first time in clinical use in 1921 and has been used worldwide by 2023. Although there are differences between studies, it is reported that side effects occur in approximately 5-20% of patients undergoing CVC. Common side effects include hematoma, venous puncture, arterial puncture, and pneumothorax, and horner syndrome is also reported in 5% of cases. In particular, in the case of the internal jugular vein (IJV), the possibility of puncture of the internal carotid artery is higher than that of other sites, and the puncture level also varies depending on the depth of needle insertion, which in some cases can cause very serious side effects. The incidence rate of side effects depends on the method of inserting the CVC and the skill of the operator. Previous method approached the IJV using the anatomy ladmark with the blind Seldinger technique, recently, as the use of ultrasound has become more common. Ultra sound guided CVC insertion tecnique reduce the incidence of side effect. However, there are still major complications exist because less experiance operator inserts needle too deep without caution and only depends on the image of sonography. Currently, the length of the needle commonly used in the CVC catheter set is 7 cm. In general, the depth from the skin to the IJV is within 1.5cm on either the right or the left, and under the premise that the needle insertion angle is 45 degrees, the distance from the skin to the IJV is within 2cm. Based on this, in previous studies, it was announced that the length of the needle required for IJV access was less than 4 cm. The purpose of this study is to study the usefulness and safety of the method of sono-guided CVC catheter insertion by fixing the needle at a position 4 cm from the needle tip by placing the suture wing (18G, single catheter set).
Central venous catheter (CVC) insertion is a common surgical procedure performed in children for the delivery of nutritional support, medications, frequent blood draws or transfusions. Maintaining hygienic conditions is absolutely necessary in order to avoid contamination of the catheter and tubing to avoid bloodstream infections. Fractures in the tubing is a common complication that places children at increased risk for infections. In order to help keep the tubing stable to avoid fractures and dislodgements, a wearable device was created called Ben-Guard. This pilot study is being undertaken to determine if the Ben-Guard device will reduce the incidence and severity of adverse events in children requiring CVCs.
This study aims to describe the incidence of catheter-related and non-catheter-related thrombosis in a population of adults in ICU and to assess its correlation with alteration of coagulation parameters.
Real-time ultrasound guidance for central venous catheter catheterism is recommended in order to reduce complication, in particular for internal jugular site1. Nevertheless, the usefulness of ultrasound guidance for subclavian approach remains controversial, in particular because needle visualisation is more complex as compared to jugular site2,3. New magnetic devices (Needle-pilotTM device, Samsung Healthcare) could theoretically allow a better needle visualisation and a better success rate. The investigators hypothesize that such device could improve the feasibility of subclavian catheterism. As this device has not been evaluated in patients, the investigators decided to perform a simulation study on a human torso mannequin. This methodology has been already used by Vogel et al in 20154. The main objective aims to compare the procedure time between conventional real time ultrasound guidance and guidance with Needle-pilot™ device.
In pediatric patients under the age of 18 who undergo surgery under general anesthesia, when inserting peripherally inserted central venous catheterization, the group that inserts the catheter with the obturator and the group that inserts the catheter without the obturator is inserted into the appropriate position.
The objective of this study is to prospectively describe the incidence of early venous thrombosis secondary to the placement of a percutaneous central venous catheter, in a pediatric intensive care unit, by systematic ultrasound screening.
An education model with a homemade jugular venous catheterization model will be compared to the conventional training model for ultrasound-guided central jugular line catheterization. The study will include 60 residents to be divided into two groups with stratified random sampling. Training session for the control group (Group 2) will include a lecture about the subject, a demo video presentation, and practice of visualization of right jugular vein on a real human subject. Training session for the model group (Group 1) will include the same as GControl with the addition of the puncture practice on the homemade jugular venous catheterization model(HJVCM) with ultrasound guidance. Both groups will be tested with another HJVCM individually and the results of the success and fail parameters will be compared.
Although ultrasound-guided catheterization of the subclavian vein is becoming standard procedure in anesthetic practice, failure to align the needle and the transducer still can lead to possibly complications. In this study, we proposed a new alignment method, namely Aiming Method. The purpose of this study is to investigate whether the use of this aiming method improved resident volunteers' performance of ultrasound-guided SC insertion in real patients. Specifically, residents were asked to perform three different methods: landmark techniques, ultrasound-guided with aiming method and ultrasound-guided plus needle guide techniques.
Central venous catheterization (CVC) in ICU is very common. It is associated with many complications. These complications are now well identified in the literature. They are primarily mechanical, infectious and thrombotic events. Many measures are taken to reduce them as the choice of insertion site, strict aseptic technique during insertion and type of catheter used. However, despite these measures, it appears that the incidence of these complications is still high. The technique of ultra-sound guided (USG) catheter insertion has shown its effectiveness in reducing complications in the general ICU population. The increase in obesity in the general population is accompanied by an increase in the obese population in the ICU (BMI > 30 kg.m-2). Many studies have investigated the effect of obesity on morbidity and mortality in ICU. Some studies found a higher rate of catheter infections in obese patient. Moreover, insertion of central venous catheter is technically more difficult in obese patients. To the investigators knowledge there are no studies on the impact of USG central venous catheterization in obese patients in ICU. The objective of this prospective randomized controlled study is to demonstrate the superiority of USG central venous catheterization (jugular or femoral) on complications in a population of obese patients. 450 patients will be included and dispatched in two groups (jugular or femoral) according to the chosen site of catheter insertion. In both groups, patients will be randomized in the USG technique or the usual anatomical technique. The rate of complications (mechanical, thrombotic or infectious) will be the primary endpoint. Secondary endpoints will be the following: rate of catheter colonization, rate of catheter-related bacteremia, rate of failure during insertion, number of punctures, procedure timing and mortality The investigators hope to establish a benefit in the use of USG central venous catheterization in obese ICU patients and thus contribute to improve the quality of care.
The primary hypothesis of this study is that occult catheter-related DVT in children with cancer is common and directly contributes to development of serious catheter complications, specifically bacteremia/fungemia and/or recurrent occlusion of the catheter tip. Accordingly, anticoagulant treatment of clinically silent (occult) DVT will reduce rates of catheter-related infection and occlusion, delays in therapy and need for catheter replacement.
