Introduction: Central venous catheterization has been usually performed during major surgeries in order of central venous pressure assessment and fluid therapy. Variety of techniques has been performed for central venous catheterization previously but the information in this regard about pediatrics is limited. In the current study, the comparison of electrocardiographic technique with landmark one for central venous catheterization performance has been done. Methods: This is a cross-sectional study conducted on 75 patients underwent central venous catheterization for elective cardiovascular thoracic surgery. In the first step, the location of catheterization was estimated based on body surface landmarks. Then catheterization was done using electrocardiography. Then by cardio-surgeon aid, during open cardiac surgery, the catheter tip location was found (gold standard). Finally, chest X-ray was taken and catheter place based on radiological markers was recorded.Results: In the current study, 75 children with age under 18 years and gender distribution of 42.7% females and 57.3% males were assessed. Mean of central venous catheter depth in gold standard method was 7.5±1.35 centimeters. Significant association between central venous catheter placement in gold standard technique and both landmark and electrocardiographic was seen (P-value<0.001; r=0.94 and P-value<0.001; r=0.77). Logistic regression showed a significant association between weight and placement of catheter tip in landmark technique (P-value=0.038) as following formula (Depth of central venous catheter= 5.33+0.07*weight).Conclusion: Our study showed that the use of ECG for CVC considering carina-to-tip as reference was superior to the landmark. In addition, catheter tip correct position was affected by weight but not height based on landmark technique.

The Ideal

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%.

Background: To evaluate novice and expert clinicians’ procedural confidence utilizing a blended learning mixed fidelity simulation model when applying a standardized ultrasound-guided central venous catheterization curriculum. Methods: Simulation-based education and ultrasound-guided central venous catheter insertion aims to provide facility-wide efficiencies and improves patient safety through interdisciplinary collaboration. The objective of this quality improvement research was to evaluate both novice (<50) and expert (>50) clinicians’ confidence across 100 ultrasound-guided central venous catheter insertion courses were performed at a mixture of teaching and non-teaching hospitals across 26 states within the United States between April 2015 and April 2016. A total of 1238 attendees completed a pre- and post-survey after attending a mixed method clinical simulation course. Attendees completed a 4-h online didactic education module followed by 4 h of hands-on clinical simulation stations (compliance/sterile technique, needling techniques, vascular ultrasound assessment, and experiential complication management). Results: The use of a standardized evidence-based ultrasound-guided central venous catheter curriculum improved confidence and application to required clinical tasks and knowledge across all interdisciplinary specialties, regardless of level of experience. Both physician and non-physician groups resulted in statistically significant results in both procedural compliance ( p < 0.001) and ultrasound skills ( p < 0.001). Conclusion: The use of a standardized clinical simulation curriculum enhanced all aspects of ultrasound-guided central venous catheter insertion skills, knowledge, and improved confidence for all clinician types. Self-reported complications were reported at significantly higher rates than previously published evidence, demonstrating the need for ongoing procedural competencies. While there are growing benefits for the role of simulation-based programs, further evaluation is needed to explore its effectiveness in changing the quality of clinical outcomes within the healthcare setting.

Abstract Background Mechanical complications arising after central venous catheter placement are mostly malposition or pneumothorax. To date, to confirm correct position and detect pneumothorax, chest x-ray film has been the reference standard, while ultrasound might be an accurate alternative. The aim of this study was to evaluate diagnostic accuracy of ultrasound to detect central venous catheter malposition and pneumothorax. Methods This was a prospective, multicenter, diagnostic accuracy study conducted at the intensive care unit and postanesthesia care unit. Adult patients who underwent central venous catheterization of the internal jugular vein or subclavian vein were included. Index test consisted of venous, cardiac, and lung ultrasound. Standard reference test was chest x-ray film. Primary outcome was diagnostic accuracy of ultrasound to detect malposition and pneumothorax; for malposition, sensitivity, specificity, and other accuracy parameters were estimated. For pneumothorax, because chest x-ray film is an inaccurate reference standard to diagnose it, agreement and Cohen’s κ-coefficient were determined. Secondary outcomes were accuracy of ultrasound to detect clinically relevant complications and feasibility of ultrasound. Results In total, 758 central venous catheterizations were included. Malposition occurred in 23 (3.3%) out of 688 cases included in the analysis. Ultrasound sensitivity was 0.70 (95% CI, 0.49 to 0.86) and specificity 0.99 (95% CI, 0.98 to 1.00). Pneumothorax occurred in 5 (0.7%) to 11 (1.5%) out of 756 cases according to chest x-ray film and ultrasound, respectively. In 748 out of 756 cases (98.9%), there was agreement between ultrasound and chest x-ray film with a Cohen’s κ-coefficient of 0.50 (95% CI, 0.19 to 0.80). Conclusions This multicenter study shows that the complication rate of central venous catheterization is low and that ultrasound produces a moderate sensitivity and high specificity to detect malposition. There is moderate agreement with chest x-ray film for pneumothorax. In conclusion, ultrasound is an accurate diagnostic modality to detect malposition and pneumothorax.

Blood Aspiration

Central venous catheterization is one of the common procedures used for gaining vascular access for various indications. Sometimes, the catheter can take unusual course inside the vein that can lead to erroneous pressure measurement, increase the risk of thrombosis or trauma to the vessel. Any resistance during insertion of the guide wire or catheter and absence of blood aspiration are some alarming signs that help to detect malposition at the earliest moment. We report a case of coiling of the shaft of the central venous catheter inside left sublacvian vein in a patient with head injury. Technical expertise, sound knowledge of anatomical landmarks and use of real time ultrasound can minimize malposition of the catheter. We suggest at any moment if there is resistance during insertion of guide wire or catheter or if there is absence of blood aspiration from any of the lumen, the catheter should be removed immediately suspecting malposition.Journal of Society of Anesthesiologists of NepalVol. 4, No. 2, 2017, page: 87-90

Abstract Background and Aims Ultrasound guidance of central venous catheter (CVC) insertion improves the safety and efficacy of its placement, but still it may not ensure correct placement of catheter tip. In our study, we aimed to identify the correct placement of CVC tip and to detect mechanical complications, by visualizing it in real time with the help of sonography and comparing this to the chest X-ray findings. Patients and Methods This was a cross-sectional observational study conducted on 80 patients with American Society of Anesthesiologists grades 1 and 2, in the age group of 18 to 65 years, who required central venous catheterization in intensive care unit. The CVC tip placement was identified with ultrasound and then the finding was compared with postinsertion chest X-ray. Results In only 9 out of the 80 patients (11.3%) malposition was detected on ultrasound and was corrected immediately, whereas in remaining 71 patients (88.8%) no intervention was required. It was observed that all the patients had correct position of CVC tip on postprocedural chest X-ray. Accidental arterial cannulation occurred in two (2.5%) patients in whom right internal jugular vein was cannulated and in two (2.5%) patients who had arrhythmia. Conclusion Ultrasonography (USG) examination can be used as a diagnostic tool method for confirmation of CVC tip and identification of cannulation-related complications. Thus, we can say that USG might obviate the need for post-CVC insertion chest X-ray.

Venous Catheterization

Central venous catheterization is the placement of a catheter in such a manner that its tip is positioned within the proximal third of the superior vena cava, the right atrium or the inferior vena cava. It is indicated when access for administration of drugs or extracorporeal blood circuits and haemodynamic monitoring or interventions is needed. When inserting a central venous catheter, appropriate preparation and asepsis, positioning of the patient, and the use of ultrasound should be considered. Compared to the landmark method of localization, ultrasound can account for anatomical variations, facilitate visualization of venous puncture, and safeguard against inadvertent arterial puncture. In the Seldinger technique, which is the primary mode of central venous catheterization, a needle is passed towards the chosen vessel. Once the needle is in the vein, a guidewire is introduced through the needle into the vessel and the needle is removed. Following a small skin incision at the base of the guidewire, a dilator is advanced over the guidewire and then taken out. Subsequent to this, the central venous catheter is railroaded over the guidewire into the vein and the guidewire is withdrawn. Complications of central venous catheterization can be mechanical, infectious or thrombotic.

Venous Catheterization

A recent case of supposed gastrointestinal (GI) bleeding in a small child underscored the difficulty inherent in making the diagnosis of Munchausen syndrome by proxy. In this case, an indwelling Broviac central venous catheter was used by the mother to withdraw blood which was then arranged to feign blood loss from her son's upper and lower GI tract. Despite the mother/perpetrator's displaying the classic personality traits of Munchausen syndrome by proxy, diagnosis was not made for many weeks.
