Abstract
Purpose To assess the safety and feasibility of intentionally positioning the catheter tip in the right atrium (RA) without an abutment during implantation of a totally implantable venous access port (TIVAP). Materials and Methods We enrolled 330 patients who had undergone TIVAP implantation between January and December 2016 and postoperative chest CT. The TIVAP was placed using the single-incision technique to access the axillary vein directly from the incision line. To position the catheter tip in the RA without abutment, blood return was checked before cutting. Catheter length and complications were evaluated by retrospectively reviewing medical images and records. Results All patients achieved successful catheter tip positioning without abutment or dysfunction. The median tip position was 15.3 mm distal to the cavoatrial junction (CAJ) on fluoroscopy and 6 mm distal to the CAJ on CT. Catheter tips migrated a median of 10.4 mm cephalically on CT compared to fluoroscopy. Thromboses were detected in the RA and superior vena cava in one patient each. Conclusion Intentional catheter tip positioning in the RA without abutment is a safe and feasible technique with a low incidence of thrombosis and no observed dysfunction.

Abstract
A first analysis of deaths due to central venous catheterization (CVC) in Japan in 2017 reported peripherally inserted central catheterization (PICC) as an alternative to CVC. In 2018, Sherlock™ 3CG (C.R. Bard Inc., New Jersey, USA) and Power PICC® became available for use in Japan. The electromagnetic mechanism of the Sherlock 3CG system often eliminates the need for the use of fluoroscopic devices, such as C-arm scanners. In this clinical report, we describe five cases of patients who underwent PICC guided by the Sherlock 3CG system and were evaluated by transesophageal echocardiography (TEE). The patients were adapted for PICC for highly invasive urologic, thoracic, and dental surgery. Also, the positions of the catheter tip were confirmed by TEE in all cases. The mean distance from the access vein to the catheter tip was 41.1 ± 3.8 cm. Chest X-ray analysis showed a mean distance of 40.0 ± 21.5 mm between the carina and catheter tip. Bicaval TEE views showed that the Power PICC tip had not been advanced into the right atrium in any of the cases. We concluded that the tip positions of the Power PICC guided by the Sherlock 3CG system were almost deeper than Zone B and not in the right atrium.

Abstract
Left subclavian venous access increases the risk of vascular damage and thrombosis based on the catheter course and location of the catheter tip. We investigated the accuracy of tip positioning with conventional landmarks using transesophageal echocardiography. The carina as a radiological landmark and the right third intercostal space as a topographical landmark were selected for tip positioning within the target zone, defined as 2 cm above and 1 cm below the right atrial junction. A total of 120 participants were randomized into two groups. The catheter insertion depth was determined as 1.5 cm more than the distance between the venous insertion point and the carina via the right first intercostal space in the radiological group, and between the venous insertion point and the right third intercostal space via the right first intercostal space in the topographical group. The determined insertion depth and actual distance to the right atrial junction of the radiological and topographical groups were 19.5 cm and 20.5 cm, and 19.8 cm and 20.4 cm, respectively. Acceptable positioning was more frequent in the topographical group (96.4% vs. 85.7%; p = 0.047). The catheter tip is more accurately positioned in the distal superior vena cava using topographical landmarks than radiological landmarks.

Abstract
Misplacement of central venous accesses can be associated with deleterious iatrogenic complications. Electrocardiography is often used to guide the placement of central venous catheters and to confirm the correct position of the catheter tip. A characteristically peaked p-wave is traditionally considered to indicate the entrance of the catheter tip into the right atrium. However, recent data show that intraarterial and even extravascular localisation might result in an increased amplitude. The peaked p-wave most likely detects the pericardial reflection rather than a right atrial catheter position, hence real-time ultrasound is to be recommended as a superior technique to confirm a correct catheter position.

Abstract
BACKGROUND Most hospital protocols-including those of our own institute-require the use of radiography to validate tip position in every central vascular access device placement. This study evaluated whether unnecessary ionizing radiation exposure could be spared in the pediatric population when intracavitary electrocardiography is used to guide catheter placement. MATERIAL AND METHODS Retrospective study of intracavitary electrocardiography-guided central vascular access device placements in our pediatric surgery department between 2013 and 2018. We evaluated the operating time, success in positioning the catheter, and accuracy of final tip position. We also assayed the effects of catheter type and of catheter access point on operating time, success, accuracy, and complications. We applied the chi-square test for statistical analysis. RESULTS In total, 622 interventions of central vascular access device placements were evaluated; 340 intracavitary electrocardiography-guided central vascular access device placements were included in the study. The electrocardiography method successfully positioned the tip of the catheter in 316/340 (92.94%) of placements. Where intracavitary electrocardiography placement was successful, radiography confirmed accuracy of tip position in 314/316 (99.41%) of placements. CONCLUSION When electrocardiography-guided positioning is uneventful and a valid P-Wave pattern is seen, postprocedure radiograph imaging for verification is unnecessary. Any effort should be made to upgrade hospital policies according to evidences and newest guidelines to spare pediatric patients harmful exposure to radiation by limiting the use of radiography only to selected cases.

Abstract
The aortic valve (AV) has been used as a surrogate marker for the superior vena cava-right atrium (SVC-RA) junction during the placement of central venous catheters. There is a paucity of evidence to determine whether this is a consistent finding in children. Eighty-seven computed tomography scans of the thorax acquired at local children's hospitals from April 2010 to September 2011 were retrospectively collected. The distance between the SVC-RA junction and the AV was measured by dual consensus. The cranio-caudal level of the junction and the AV were referenced to the costal cartilages (CCs) and anterior intercostal spaces (ICSs). The results confirmed that the SVC-RA junction has a variable relationship to the AV. The junction was on average 3.1 mm superior to the AV. This distance increased with age. In the <1-year-old age group, the junction was on average 1.3 mm superior to the AV (range: -6 to 11 mm). In the 1-2 years old age group: 3.5 mm (range: -8 to 15 mm). In the 3-6 years old: 3.8 mm (range: -9 to 13 mm). In the >7 years old age group: 4 mm (range: -11 to 16 mm). The surface anatomy of the SVC-RA junction was variable, ranging from the second ICS to sixth CC. The SVC-RA junction has a predictable relationship to the AV, and this can be used as an adjunct marker for accurate placement of central venous catheters except in the smallest neonates. Clin.

Abstract
Background and Aims Central venous catheterization is a frequently performed procedure in anesthesia and critical care, and is indispensable in the practice of emergency medicine. Correct positioning of the central venous catheter (CVC) tip is often regarded as a secondary goal and there are various complications that can occur due to abnormal position of the catheter tip. Different methods have been advocated to guide accurate prediction of optimal CVC depth insertion before or during the procedure at the bedside. Material and Methods A prospective randomized double blinded study was conducted in 180 patients aged between 18 to 65 years requiring central venous catheterization. The optimal depth of insertion of right internal jugular vein (IJV) catheter using three different techniques, Peres' formula method, Landmark technique and Intra atrial Electrocardiography (ECG) guided technique was performed and the three techniques were compared with respect to optimal positioning using carina as a landmark in post procedural chest radiograph. Correct position of the catheter tip was considered upto 1 cm above or below the carina in post procedure X ray. Results The average final depth of insertion was 15.30 ± 0.62 cms in the Formula group, 12.74 ± 0.77 cms in landmark group and 12.64 ± 0.70 cms in ECG group. The vertical distance from carina was 0.91 ± 0.94 cms in formula group, 0.54 ± 0.67 cms in landmark group and 0.53 ± 0.43 cms in ECG group. The CVC tip was properly positioned within 1 cm above and below the carina in 58.33% patients in the formula group, 93.33% patients in landmark group and 96.67% patients in ECG group. Conclusion We conclude that both landmark guidance and ECG guidance are comparable with regard to accurate central venous catheter tip positioning when CVCs are placed through right internal jugular vein whereas formula based technique is least accurate and results in over insertion of CVCs.

Abstract
Objectives: To confirm the feasibility of intracavitary electrocardiogram guidance to verify tip’s position during insertion of peripherally inserted central catheter and to identify clinical factors or intracavitary electrocardiogram patterns associated with aberrant tip’s position. Methods: A prospective study was conducted in our university hospital after authorization of the ethics committee. All patients addressed for peripherally inserted central catheter insertion were included and received the insertion using intracavitary electrocardiogram and electromagnetic guidance. Side of insertion and three electrocardiogram factors were collected: visualization of P-wave at baseline (sinusal rhythm), acquisition of the maximal P-wave and the negative deflection. All patients had a systematic post-procedural chest X-ray. One of the investigators assessed all chest X-ray, blinded to the results of intracavitary electrocardiogram, and confirmed whether the tip’s position on chest X-ray matched with the intracavitary electrocardiogram information or if the tip was malpositioned on chest X-ray (mismatch with intracavitary electrocardiogram or aberrant position). Factors associated with malposition were described. Results: From January 2015 to April 2015, 330 patients were eligible, 5 had an uninterpretable chest X-ray, and 14 were non-sinusal at baseline. Our main analysis population included 311 patients. We observed a mismatch between intracavitary electrocardiogram and chest X-ray estimate of the tip’s position in 3 cases (1%) and an aberrant tip’s position occurred in 3 cases (1%). Incidence of malposition was higher in the group of patients with non-sinusal rhythm (14%) and when the catheter was inserted on the left side (7%). Conclusion: This study confirmed the feasibility of intracavitary electrocardiogram for peripherally inserted central catheter positioning and the limits of chest X-ray. Insertion on left side may represent risk factor for aberrant position but our study lacked power to establish a statistical link.

Abstract
Background The current standard followed for assessing central venous catheter (CVC) tip placement location is through radiological confirmation using chest X-ray (CXR). Placement of CVCs under electrocardiogram (ECG) guidance may save cost and time compared to CXR. Objective The objective of this study is to compare the accurate placement of the CVC tip using anatomical landmark technique with ECG-guided technique. Another objective is to compare CVC placement time and postprocedural complications between the two techniques. Methods and Materials A total of 144 adult individuals, who were critically ill and required CVC placement in the Emergency Department, were included for the study. Study duration was 6 months. Anatomical landmark and ECG-guided groups were assigned 72 participants each. Analyses were performed using t and Chi square-tests. Results It was observed that 13 (18%) in the landmark technique were malpositioned as compared to none in the ECG-guided technique (P = 0.000). The landmark group had 22 (30.6%) participants with arrhythmias during the procedure, compared to none in the ECG-guided group (P = 0.000). The landmark group revealed that 30 (41.7%) of the CVC were overinserted and required immediate repositioning, compared to none in the ECG-guided group (P = 0.000). Conclusion ECG-guided technique was found to be more accurate for CVC tip placement than the anatomical landmark technique. Furthermore, the ECG-guided technique was more time-effective and had less complications than the anatomical landmark technique. Hence, ECG-guided CVC placement is relatively accurate, efficient, and safe and can be considered as an alternative method to conventional radiography for confirmation of CVC tip placement.

Abstract
BACKGROUND Few reports exist regarding the optimal depth of a left-sided central venous catheter in pediatric patients. We aimed to provide a guideline for the optimal depth of central venous catheters at the left internal jugular vein in infants, using anatomical landmarks, age, height, and weight. METHODS A two-stage study was conducted. In the first observational study, infants aged ≤1 year and scheduled for elective surgery requiring a central venous catheter were enrolled. The tip of the central venous catheter was confirmed using transthoracic echocardiography. Linear regression modeling was performed to determine the association between the insertion depth of the central venous catheter and the I-A-B distance (I, the insertion point; A, the sternal head of the left clavicle; B, the midpoint of the perpendicular line drawn between the sternal head of the right clavicle and an imaginary line between the nipples), based on age, height, and weight. In the second study, the results of the first study were validated in another group of consecutive infants. RESULTS In the first study, the data of 67 patients were analyzed. The infant's height and I-A-B distance were highly correlated with the level of the central venous catheter tip (R2 =0.763 and 0.772, respectively; all P < .01), using the regression equations 0.11 × height (cm) + 0.19 and 1.02 × I-A-B (cm) + 1.55, respectively. In the second study, height was also highly correlated with the insertion depth of the central venous catheter in another 42 infants (r = .938, P = <.001). In a Bland-Altman's analysis, the mean bias and precision of the actual insertion depth and predicted depth using height were 0.09 and 0.15 cm, respectively. The limits of agreement were -0.19 and 0.38 cm, respectively. CONCLUSION In infants, the optimal depth of a central venous catheter at the left internal jugular vein can be determined with a simple formula using height.

Abstract
Background and Aims: The complications of central venous catheterisation can be minimized by ensuring catheter tip placement just above the superior vena cava-right atrium junction. We aimed to compare two methods, using an electrocardiogram (ECG) or landmark as guides, for assessing correct depth of central venous catheter (CVC) placement. Methods: In a prospective randomised study of sixty patients of <12 years of age, thirty patients each were allotted randomly to two groups (ECG and landmark). After induction, central venous catheterisation was performed by either of the two techniques and position of CVC tip was compared in post-operative chest X-ray with respect to carina. Unpaired t-test was used for quantitative data and Chi-square test was used for qualitative data. Results: In ECG group, positions of CVC tip were above carina in 12, at carina in 9 and below carina in 9 patients. In landmark group, the positions of CVC tips were above carina in 10, at carina in 4 and below carina in 16 patients. Mean distance of CVC tip in ECG group was 0.34 ± 0.23 cm and 0.66 ± 0.35 cm in landmark group (P = 0.0001). Complications occurred in one patient in ECG group and in nine patients in landmark group (P = 0.0056). Conclusion: Overall, landmark-guided technique was comparable with ECG technique. ECG-guided technique was more precise for CVC tip placement closer to carina. The incidence of complications was more in the landmark group.

Abstract
OBJECTIVE We assessed and compared two landmarks (conventional vs. high approach) used in internal jugular vein (IJV) cannulation with respect to the degree of overlap with the carotid artery (CA) and the cross-sectional area (CSA) of the IJV using ultrasonography. PATIENTS AND METHODS Forty-eight adult patients were included. Using ultrasonography, the percentage overlaps with the CA and the CSA of both IJVs were measured in the supine and Trendelenburg positions using conventional and high approaches. With the conventional approach, the IJV is penetrated at the apex of Sedillot's triangle, formed by the clavicle and the sternal and clavicular heads of the sternocleidomastoid muscle. The high approach involves the midpoint between the sternal notch and the mastoid process. RESULTS The degree of overlap with the CA was 30.5 (7.5-69.4)% [median (interquartile range)] and 0.0 (0.0-25.4)% with the conventional and high approaches, respectively, for the right IJV (P<0.001) in the Trendelenburg position with 30° head rotation. The CSA of the right IJV was 1.22 (0.92-2.01) and 0.98 (0.79-1.72) cm with the conventional and high approaches, respectively (P<0.001), in the Trendelenburg position with 30° head rotation. IJV was more deeply positioned using the high approach than the conventional approach (P<0.001). CONCLUSION The high approach for IJV cannulation decreased both the degree of overlap with the CA and CSA of the IJV and increased the depth of the IJV from the skin compared with the conventional approach.

Abstract
The supraclavicular fossa ultrasound view can be useful for central venous catheter (CVC) placement. Venipuncture of the internal jugular veins (IJV) or subclavian veins is performed with a micro-convex ultrasound probe, using a neonatal abdominal preset with a probe frequency of 10 Mhz at a depth of 10-12 cm. Following insertion of the guidewire into the vein, the probe is shifted to the right supraclavicular fossa to obtain a view of the superior vena cava (SVC), right pulmonary artery and ascending aorta. Under real-time ultrasound view, the guidewire and its J-tip is visualized and pushed forward to the lower SVC. Insertion depth is read from guidewire marks using central venous catheter. CVC is then inserted following skin and venous dilation. The supraclavicular fossa view is most suitable for right IJV CVC insertion. If other insertion sites are chosen the right supraclavicular fossa should be within the sterile field. Scanning of the IJVs, brachiocephalic veins and SVC can reveal significant thrombosis before venipuncture. Misplaced CVCs can be corrected with a change over guidewire technique under real-time ultrasound guidance. In conjunction with a diagnostic lung ultrasound scan, this technique has a potential to replace chest radiograph for confirmation of CVC tip position and exclusion of pneumothorax. Moreover, this view is of advantage in patients with a non-p-wave cardiac rhythm were an intra-cardiac electrocardiography (ECG) is not feasible for CVC tip position confirmation. Limitations of the method are lack of availability of a micro-convex probe and the need for training.

Accurate nonfluoroscopic guidance and tip location of peripherally inserted central catheters using a conductance guidewire system. J Vasc Surg Venous Lymphat Disord 2013; 1:202-208.e1. [PMID: 26992344 DOI: 10.1016/j.jvsv.2012.10.065] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2012] [Revised: 10/25/2012] [Accepted: 10/27/2012] [Indexed: 11/28/2022]
Abstract
BACKGROUND Bedside placement of peripherally inserted central catheters (PICCs) may result in navigation to undesirable locations, such as the contralateral innominate or jugular vein, instead of the superior vena cava or right atrium. Although some guidance and tip location tools exist, they have inherent limitations because of reliance on physiological measures (eg, chest landmarks, electrocardiogram, etc), instead of anatomical assessment (ie, geometric changes in the vasculature). In this study, an accurate, anatomically based, non-X-ray guidance tool placed on a novel 0.035" conductance guidewire (CGW) is validated for PICC navigation and tip location. METHODS The CGW system uses electrical conductance recordings to assess changes in vessel cross-sectional area to guide navigation of the PICC tip. Conductance rises and oscillates when going in the correct direction to the superior vena cava/right atrium, but drops when going in the incorrect direction away from the heart. Bench and in vivo studies in six swine were used to confirm the accuracy and repeatability of the PICC placement at various anatomical locations. The PICC tip location was confirmed by direct visualization vs the desired location. RESULTS CGW PICC guidance was highly accurate and repeatable with virtually no difference between actual and desired catheter tip location. The difference between the CGW PICC location vs the desired target was -0.07 ± 0.07 cm (6.6% error) on the bench and 0.04 ± 0.10 cm (5% error) in vivo. No complications or adverse events occurred during CGW usage. CONCLUSIONS The CGW provides an anatomically based, reproducible, and clinically significant method for PICC navigation and tip location that can improve accuracy, decrease the wait time prior to therapy delivery, decrease cost, and minimize the need for X-ray. These findings warrant clinical evaluation of this navigation tool for PICC line placement.

Abstract
PURPOSE The aim of this multicenter study was to assess the feasibility, safety, and accuracy of the intracavitary ECG method for real-time positioning of the tip of different types of central venous catheters. METHODS A total of 1444 catheter insertions in adult patients were studied in eight Italian centers (539 ports, 245 PICCs, 325 tunneled CVCs, 335 non-tunneled CVCs). Patients with no visible P wave at the standard baseline ECG were excluded. Depending on the type of catheter and its purpose, the target was to position the tip either (a) at the cavo-atrial junction, or (b) in the lower third of the superior vena cava, or (c) in the upper part of the atrium. The final position was verified by a post-procedural chest x-ray. RESULTS The method was feasible in 99.3% of all cases. There were no complications potentially related to the method itself. At the final x-ray control, 83% of all tips were positioned exactly at the target; 12.4% were positioned within 1-2 cm from the target, but still in a correct central position; only 3.8% were malpositioned. The mismatch between intra-procedural ECG method and post-procedural x-ray was significantly lower when the x-ray was taken in supine position. CONCLUSIONS Our multicenter study confirms that the intracavitary ECG method for real time verification of tip position is accurate, safe, feasible in all adult patients and applicable to any type of short-term or long-term central venous access device.

Abstract
PURPOSE Appropriate tip position of totally implantable central venous catheters is essential in order to prevent catheter-related complications, in particular thrombosis. Endovascular electrocardiography is an economic and safe method to guide placement of catheters into the central veins. Although widely utilized, there is still lack of conclusive evidence about its efficacy. The aim of the study was to assess the efficacy and safety of endovascular electrocardiographic guided placement compared to the anthropometric method. METHODS Endovascular ECG was employed to guide electrocardiographic placement of a central venous catheter in a cohort of oncologic patients. The rate of correct placement and the incidence of catheter-related thrombosis were considered. Patients in which central venous catheters were inserted with the anthropometric technique were considered as control group. RESULTS The rate of correct placement was 91% and 50% for ECG-guided and anthropometric catheters (p<0.0001) respectively. None of the patients suffered from early insertion-related complications. The rate of catheter-related vascular thrombosis was lower for ECG-guided catheters (3.6% vs. 9.6%, n.s.), in particular for left-inserted catheters (0% vs. 33.3%, p=0.02). CONCLUSION Endovascular electrocardiography was more effective than the anthropometric technique in placement of implantable central venous catheters and was associated with a lower incidence of catheter-related thrombosis, in particular for those inserted from the left-side.

Abstract
Tip position of a central venous access is of paramount importance and should be verified before starting infusion. Intra-procedural methods for verifying the location of the tip are to be preferred, since they avoid the risks, delays and costs of repositioning the tip. Among the intra-procedural methods, the electrocardiography (EKG) method has many advantages since it is as accurate as fluoroscopy, but simpler, more readily available, less expensive, safer and more cost-effective. The only contraindication to utilizing the EKG method is the difficulty in identifying the standard P-wave on a surface EKG (this happens - usually because of severe arrhythmias, such as atrial fibrillation - in only approximately 7% of cases: although such patients are easily identified before the procedure, and are referred to other methods for tip positioning). When dealing with the insertion of peripherally inserted central catheters (PICC), the EKG method (using the column of saline technique) virtually has no risk of false positives. The EKG method removes the need for the post-procedural chest x-ray, as long as there is no expected risk of pleuropulmonary damage to be ruled out (example: ultrasound guided central venipuncture for central venous catheter insertion or any kind of PICC insertion). In conclusion, evidence is mounting that the EKG method may be a valid and cost-effective alternative to the standard radiological control of the location of the tip of any central venous access device (VAD), and that will rapidly become the preferential method for confirming the tip position during PICC insertion.

Abstract
INTRODUCTION To develop a simple method for safely placing central venous catheters (CVCs) outside the heart from the subclavian or internal jugular vein in compliance with Food and Drug Administration (FDA) and manufacturer guidelines. METHODS Patients requiring CVCs were enrolled into this prospective trial. Central venous catheters were inserted into the subclavian or internal jugular vein from either the right or left side to a depth of 15 cm. Chest radiographs were obtained immediately after insertion of the catheter to check tip placement and to evaluate for mechanical complications. RESULTS Operators successfully placed 201 of 210 (96%) CVCs outside the heart. Six of these required repositioning. Nine catheter tips were located in an intracardiac position. No cases of pneumothorax, hemothorax, or pericardial tamponade occurred. One case of delayed hydrothorax due to superior vena cava injury occurred. CONCLUSIONS Using a 15-cm insertion depth via the internal jugular or subclavian vein results in safe catheter tip location in the majority of procedures consistent with FDA and manufacturer guidelines.

Abstract
Abstract
Background: Long term venous catheters have been used to deliver specialized therapies since 1968. The ideal tip position of a central venous catheter provides reliable venous access with optimal therapeutic delivery, while minimizing short-and long-term complications. Ideal position limits have evolved and narrowed over time, making successful placement difficult and unreliable when depending exclusively on the landmark technique.
Objective: To review and analyze contemporary literature and calculate an overall accuracy rate for first attempt placement of a PICC catheter in the ideal tip position.
Methods: Key PICC placement terms were used to search the database PubMED-indexed for MEDLINE in June and October, 2009. The selection of studies required: a patient cohort without tip placement guidance technology; a documented landmark technique to place catheter tips; data documenting initial catheter placement and, that the lower third of the SVC and the cavo-atrial junction (CAJ) were included in the placement criteria. With few exceptions, articles written between 1993 and 2009 met the stated selection criteria. A composite of outcomes associated with tip placement was analyzed, and an overall percent proficiency of accurate catheter tip placement calculated.
Results: Nine studies in eight articles met the selection criteria and were included for analysis. Rates of first placement success per study ranged from 39% to 75%, with the majority (7/9) being single center studies. The combined overall proficiency of these studies calculated as a weighted average was 45.87%.

Abstract
Central venous catheters are routinely placed in patients undergoing major surgeries where expected volume and hemodynamic disturbances are likely consequences. The incorrect positioning may give false central venous pressure (CVP) readings leading to incorrect volume replacement and other serious complications. 50 American Society of Anaesthesiologists grade II-IV patients aged 18-60 years were selected for right-sided internal jugular vein (IJV) catheterization using Seldinger's technique. In group A, central venous catheterization was done under electrocardiography (ECG) guidance. In group B, the catheter was inserted blindly using Peres' formula of “height (in cm)/10”. The position of the tip of central venous catheter was confirmed radiologically by postoperative chest X-ray. 92% of patients in group A had radiologically correct positioning of catheter tip i.e. above the carina, while in group B 48% patients had over-insertion of the catheter in to the right atrium. Intra-atrial ECG technique to judge correct tip positioning is simple and economical. It can determine the exact position intraoperatively and can justify a delayed postoperative chest X-ray to confirm CVC line tip placement.

Abstract
Catheter type, access technique, and the catheter position should be selected considering to the anticipated duration of PN aiming at the lowest complication risks (infectious and non-infectious). Long-term (>7-10 days) parenteral nutrition (PN) requires central venous access whereas for PN <3 weeks percutaneously inserted catheters and for PN >3 weeks subcutaneous tunnelled catheters or port systems are appropriate. CVC (central venous catheter) should be flushed with isotonic NaCl solution before and after PN application and during CVC occlusions. Strict indications are required for central venous access placement and the catheter should be removed as soon as possible if not required any more. Blood samples should not to be taken from the CVC. If catheter infection is suspected, peripheral blood-culture samples and culture samples from each catheter lumen should be taken simultaneously. Removal of the CVC should be carried out immediately if there are pronounced signs of local infection at the insertion site and/or clinical suspicion of catheter-induced sepsis. In case PN is indicated for a short period (max. 7-10 days), a peripheral venous access can be used if no hyperosmolar solutions (>800 mosm/L) or solutions with a high titration acidity or alkalinity are used. A peripheral venous catheter (PVC) can remain in situ for as long as it is clinically required unless there are signs of inflammation at the insertion site.

Abstract
PURPOSE To investigate the reliability of intra-atrial electrocardiogram (ECG) use for external jugular vein (EJV) catheterization. MATERIALS AND METHODS Patients undergoing open heart surgery in Suleyman Demirel University Hospital between February and June 2006 were included in the study. Using a sterile Seldinger technique, a triple lumen polyurethane central venous catheter was introduced (Certofix Trio V 720, length 20 cm, 7 French) under intra-atrial ECG guidance. The presence of an increase in P-wave size was recorded. Just after the surgery, a portable chest X-ray was taken. The method was considered to be successful when a change in P-wave could be seen and the catheter was in the superior vena cava, as well as when there was no change in P-wave and the catheter was not in the superior vena cava. RESULTS In six patients (12%), we were not able to advance the guidewire. In the remaining 44 patients, the catheter was inserted without problem. Eight of these 44 catheters were positioned in the innominate vein, with a malposition ratio of 18%. The success rate of external jugular vein cannulation with intra-atrial ECG was 95%. No complications occured related to the EJV cannulation. CONCLUSION Considering that it is easily accessed without complication, and the malposition is successfully detected by intra-atrial ECG, EJV is a suitable access for central venous cannulation when internal jugular vein (IJV) is not usable.

Abstract
Abstract
Two preliminary studies were conducted to determine feasibility of using the electrocardiography (EKG) method to determine terminal tip location when inserting a peripherally inserted central catheter (PICC). This method uses the guidewire inside the catheter (or a column of saline contained in the catheter) as an intracavitary electrode. The EKG monitor is then connected to the intracavitary electrode. The reading on the EKG monitor reflects the closeness of the intracavitary electrode (the catheter tip) to the superior vena cava (SVC). The studies revealed that the EKG method was extremely precise; all tips placed using the EKG method and confirmed using x-ray were located in the superior vena cava. In conclusion, the EKG method has clear advantages in terms of accuracy, cost-effectiveness, and feasibility in conditions where x-ray control may be difficult or expensive to obtain. The method is quite simple, easy to learn and to teach, non-invasive, easy to reproduce, safe, and apt to minimize malpositions due to failure of entering the SVC.

Abstract
BACKGROUND Traditionally, the positioning of central venous catheters (CVCs) outside the right atrium (RA) in patients receiving intensive care is determined by surrogate landmarks on bedside chest radiographs (CXRs). The validity of this method was examined by comparing readings of radiologists with the results of transesophageal echocardiography (TEE). METHODS Prospective study at university hospital. Two hundred thirteen adults scheduled for cardiothoracic surgery were randomized to right or left internal jugular vein catheterization under ECG guidance. One senior radiologist and two radiologists in training independently read the CXRs, and determined whether the CVC tip ended in the RA and measured the vertical distance from the CVC tip to the carina (TC-distance). RESULTS Two hundred twelve CVC tips could be identified by TEE. Only left-sided CVCs (n = 5) ended in the upper RA (2.4%). Three of those patients were shorter than 160 cm. Specificity was 94% for senior radiologist, 44% for the first radiologist in training, and 60% for the second radiologist in training. The TC-distance of intraatrial catheters was 39, 55, 59, 80, and 83 mm, respectively. Thus, a TC-distance < or = 55 mm ensured extraatrial tip position in four of five intraatrial CVCs (80%, p = 0.002). The TC-distance of extraatrial catheters ranged from - 26 to 102 mm. CONCLUSIONS Reading of a bedside CXR alone is not very accurate to identify intraatrial CVC tip position. TC-distance is a helpful marker, and its specificity is as good as that of an experienced radiologist if a cutoff value of 55 mm is chosen.

Abstract
BACKGROUND Electrocardiogram (ECG) guidance to confirm accurate positioning of central venous catheters (CVC), placed before surgery in the operating room, is rarely used in the United States. We designed this randomized, controlled trial to investigate whether the use of this technique impacts the accuracy of CVC placement. METHODS Patients in group ECG (n = 147) had a CVC placed using right-atrial ECG to guide catheter tip positioning. CVCs in group NO-ECG (n = 143) were positioned without this technique. RESULTS Overall, guidewire-ECG control resulted in more correctly positioned CVCs (96% vs 76%, P < or = 0.001) without increasing placement time. Significantly more CVCs were placed in the middle of the superior vena cava in group ECG (P < or = 0.001), although placement into the right atrium or right ventricle and into other vessels occurred significantly more often in group NO-ECG (P < or = 0.001). Twenty patients in group NO-ECG required repositioning of their CVC after surgery, whereas this maneuver was necessary only in three patients in group ECG (P < or = 0.001). CONCLUSIONS ECG guidance allows for more accurate CVC placement, and should be considered to increase patient safety and reduce costs associated with repositioning procedures.

Abstract
PURPOSE To facilitate electrocardiography (ECG)-guided central venous catheter placement by observing the shape and size of the P wave at specific locations of a central venous catheter (CVC) tip. METHODS We evaluated 54 patients for whom central venous catheterization was planned as part of routine care for their elective surgery. The junction of the superior vena cava (SVC) and the right atrium (RA) was defined as the superior border of the crista terminalis by transesophageal echocardiography. The RA ECGs were recorded while withdrawing the CVC into the SVC or advancing it into the RA at 1-cm intervals. Saline was used as an electrical conductor via the distal lumen of the CVC. RESULTS The tallest peaked and biphasic P waves [median (interquartile range)] were observed when the CVC tip was located at positions 0.0 cm (-1.0 to 0.0) and -4.0 cm (-5.0 to -3.0) below the SVC/RA junction, respectively. The P wave returned to a normal shape and size at 4.0 cm (3.0 to 4.0) above the SVC/RA junction. Overshoot P waves were observed at - 4.0 cm (-5.0 to -3.0) below the SVC/RA junction in 22 patients, when the CVC tip appeared to be contacting or in close proximity to the RA wall. CONCLUSIONS During ECG-guided central venous catheterization, the tallest peaked P wave may be used to place the CVC tip at the SVC/RA junction, the normally-shaped P wave identifies the mid to upper SVC, and biphasic P waves identify RA localization.

Abstract
OBJECTIVE Radiographically, a central venous catheter (CVC) tip should lie at the level of the right tracheobronchial angle. Precalculation of length of CVC insertion may avoid unnecessary catheter malposition. The purpose of this study was to assess the accuracy of a method of CVC positioning, based on external topographic landmarks. DESIGN A prospective, randomized study. SETTING University-affiliated hospital, single institution. PARTICIPANTS Patients scheduled for surgery. INTERVENTIONS Patients were allocated for insertion of the catheter through the right internal jugular vein to either a fixed, predetermined, 15-cm length (n = 50) or to a depth calculated topographically (n = 50) by drawing a line from the level of the thyroid notch to the sternal manubrium. The catheter was repositioned if its tip was situated >5 cm above the carina or >1 cm below it. The distance from the catheter tip to the carina was measured. The main study endpoint was the need for catheter repositioning. MEASUREMENTS AND MAIN RESULTS Two percent of patients required repositioning in the topographic group compared with 78% in the 15-cm length group (p < 0.001). No patient in the topographic group and 10 patients (20%) in the 15-cm group had the catheter placed in the right atrium (p < 0.05). The mean distance from the CVC tip to the carina was 2.9 +/- 1.4 cm above the carina in the topographic group and 1.9 +/- 1.1 cm below the carina in the 15-cm length group (p < 0.001). No patient had a too proximally placed catheter. Insertion lengths in the topographic group ranged between 9 and 12.5 cm. CONCLUSIONS It is recommended to use the topographic approach in deciding CVC depth with right internal jugular CVC placement.

Abstract
Appropriate positioning of the right atrial air aspiration catheter is critical to successful aspiration of air. The intravascular electrocardiography patterns currently used to position the right atrial air aspiration catheter have not been validated by echocardiography. In 10 patients, using simultaneous transesophageal echocardiography and intravascular electrocardiography, we found that the largest monophasic P wave without a biphasic component correlated with the right atrial-superior vena cava junction. Using this pattern, we performed a prospective trial on 10 subjects and demonstrated appropriate positioning in only 8. This preliminary study suggests that intravascular electrocardiography may not yield appropriate positioning in all patients.

Abstract
OBJECTIVE Central venous catheterization is associated with a significant incidence of complications (5%-20%). The incidence of perforation is approximately 0.25% to 0.4%. To prevent cardiac tamponade associated with a high risk of death, Food and Drug Administration guidelines state that the tip of a central venous catheter (CVC) should not be placed in, or allowed to migrate into, the heart. Therefore, in order to prevent cardiac tamponade, a catheter should be placed above the pericardial reflection. Thus, the intrapericardial length of the superior vena cava (SVC) was studied. Neither the pericardial reflection nor the exact entrance to the right atrium (RA) can be identified by chest x-ray. The goal of this study was to evaluate the variability of the intrapericardial section in relation to the SVC. DESIGN Observational study. INTERVENTIONS The absolute length of the SVC, the upper edge of the pericardial reflection on the SVC, and the lateral and the medial intrapericardial sections of the SVC were recorded and statistically analyzed. SETTING Medical school: dissecting room at the Department of Anatomy. STUDY POPULATION Eighteen formalin-preserved adult cadavers. MEASUREMENTS AND MAIN RESULTS The median lengths measured were as follows: total SVC, 61 mm; intrapericardial section of the medial SVC, 32.5 mm; and lateral SVC, 20.5 mm. The intrapericardial section was related to the total length of the SVC on both sides (Spearman rank order, p < 0.05). The median difference of the SVC covered with pericardium between the lateral and medial side was 11 mm (range, 5-21). In 15 of 18 cadavers, the pericardial reflection ran within the medial third of the SVC. The lower third of the SVC was regularly covered by the pericardium. The duplication of the pericardium crossed the SVC in the medial third at a diagonal to horizontal angle. CONCLUSIONS Catheters ending below the pericardial reflection, hence positioned in the caudal third of the SVC, are likely to run along the long axis of the vein and the risk for perforation is minimized. Therefore, the authors recommend placing all catheters below the pericardial reflection. According to the present data, CVCs placed approximately 30 mm above the RA border, thus complying with the Food and Drug Administration guidelines, still may have their tips positioned below the pericardial reflection. In this position, pericardial tamponade still may occur. Perforation above the pericardial reflection will result in a hemo- or hydrothorax/mediastinum. A bedside method to determine the position of the CVC with respect to the pericardial reflection (eg, electrocardiographic guidance) should be used.

Abstract
BACKGROUND Many publications, including the instructions accompanying central venous catheters, state that it is negligent to site the catheter tip in the right atrium. If the catheter tip is above the carina on a post-procedure radiograph then it is generally accepted that the catheter lies outside the right atrium. It is also recommended that the catheter tip should lie in the long axis of the superior vena cava without acute abutment to the vein wall. We performed a retrospective audit of the position of central venous catheter tips on routine post-procedure chest radiographs in intensive care unit patients, to see if these potentially conflicting requirements had been met. METHODS We identified 213 central venous catheters suitable for analysis, within a study population of 200 consecutive cases. We measured the distance of the central venous catheter tip above or below the carina and the angle of the central venous catheter tip to the vertical (a surrogate marker for the angle of abutment of the tip to the approximately vertical superior vena cava wall). RESULTS For right-sided catheters there was a high (74/163) number placed with their tips below the carina, but a very low number (4/163) with their tips at a steep (>40 degrees ) angle to the vertical. For left-sided catheters very few (7/50) were placed with their tips below the carina, but for those 43 sited above the carina most could be considered to be in suboptimal positions. This was because they were either too high and had not even crossed the midline (9), or had an acute angle (>40 degrees ) between the tip and the vertical (27). CONCLUSIONS We suggest that for left-sided catheters placement of the tip below the carina is more likely to result in a satisfactory placement.

Abstract
BACKGROUND Intraatrial electrocardiography (ECG) is a well-established method for central-venous catheter (CVC) placement and an intraatrial position is assumed, when a significantly increased P-wave is registered. However, an increase in P-wave amplitude also occurs in other positions. Therefore we evaluated CVC tip positioning by means of transesophageal echocardiography (TEE) at a maximum P-wave amplitude. PATIENTS AND METHODS In this prospective randomized study the right or left internal jugular vein was cannulated with 100 patients in each group and catheter tip positioning was guided by means of ECG. The catheter was fixed at the position of maximum P-wave amplitude and the insertion depth was registered. The relationship of the CVC tip position to the superior edge of the crista terminalis was demonstrated with the help of TEE. RESULTS In all patients the catheter tip was found +/- 0.5 cm from the superior edge of the crista terminalis at the transition from the superior vena cava to the right atrium. On x-ray control, all catheters ran along the length of the vessel wall of the superior vena cava. CONCLUSIONS A maximum P-wave is derived even at the entrance to the right atrium. This explains why ECG-guided CVC placement -- based on the largest P-wave amplitude -- consistently resulted in correct positioning of the CVC tip at the transition from the superior vena cava to the right atrium.

Abstract
BACKGROUND Insertion of a central venous catheter (CVC) in an emergency situation is challenging and may be potentially associated with more complications. Because CVC positioning by ECG-guidance may help to decrease the frequency of a malpositioned catheter, we decided to prospectively evaluate the usefulness of positioning a CVC by ECG-guidance during prehospital emergency care. METHODS Prospective observational study during which all patients requiring CVC placement during prehospital care were included. We compared two periods of 1 year during which CVCs were inserted without and then with the help of ECG-guidance. RESULTS Eighty successive patients were included. We observed a significant reduction of incorrectly positioned CVCs with ECG-guidance (13% vs. 38%, P < 0.05) and a decreased number of chest X-rays needed to verify the position of the CVC (40 vs. 54, P < 0.05). CONCLUSION ECG-guidance is a safe and feasible technique which significantly improved the rate of CVCs correctly positioned during prehospital emergency care.

Abstract
BACKGROUND The classic increase in P wave size, known as 'P-atriale', is a widely accepted criterion for determination of proper positioning of central venous catheter tips. Recent transoesophageal echocardiography (TOE) studies did not confirm intra-atrial position despite advancing the central venous catheter further than indicated by ECG guidance. We postulate that the pericardial reflection rather than the entry into the right atrium corresponds to the ECG changes. In order to test our hypothesis we sought to determine the anatomical substrate for the electrical changes in an animal study. Subsequently, a modified version of the study was undertaken in man and is also reported. METHODS In six juvenile pigs the left external jugular vein and right carotid artery were cannulated. A triple-lumen central venous catheter was positioned by ECG guidance using a Seldinger wire as an exploring electrode. The venous and arterial catheters were suture fixed 2 cm beyond the onset of an increase in P wave size. The corresponding anatomical catheter tip position was determined by open exploration of the vessels and the heart. Subsequently the catheter tip position (during advancement) of a pulmonary artery catheter and the corresponding electrical ECG changes were examined in 10 patients during open chest cardiac surgery. RESULTS All catheters-arterial and venous, in animals and humans-revealed an increase in size of the P wave as well as the QRS complex. All venous catheters were positioned in the superior vena cava, beyond the pericardial reflection but outside the right atrium. All arterial catheters were positioned in the ascending aorta thus also beyond the pericardial reflection. CONCLUSIONS The start of an increase in P wave size does not correspond with the entrance of the right atrium. The anatomic equivalent for the electrophysiological changes of the ECG is the pericardial reflection. ECG guidance is unable to distinguish between venous and arterial catheter position.
