The tip and die for manufacturing multi-lumen catheter tubes should be designed considering the flow velocity of the molten polymer and the deformation of the final extruded tube. In this study, to manufacture non-circular double-lumen tubes for peripherally inserted central catheters (PICCs), three types of tip and die structures are proposed. The velocity field and swelling effect when the circular tip and die (CTD) are applied, which is the commonly used tip and die structure, are analyzed through numerical calculation. To resolve the wall and rib thickness and ovality issues, the ellipse tip and die (ETD) and sub-path tip and die (STD) were proposed. In addition, based on the results of numerical analysis, the tip and die structures were manufactured and used to perform extrusion. Finally, we manufactured tubes that satisfied the target diameter, ovality, wall, and rib thickness using the newly proposed STD.

ABSTRACT Objective: to analyze the results of insertion procedures of Peripherally Inserted Central Catheters in newborns using two measurement methods. Methods: this is a randomized clinical trial, presenting descriptive and exploratory results of variables. It was held at a Neonatal Intensive Care Unit. Data were collected between September 2018 and 2019. The sample analyzed was 88 catheter insertion procedures, distributed in two groups. Study approved by an Institutional Review Board and obtained registration in the country and abroad. Descriptive analysis and logistic regression of data. Results: modified measurement obtained a significant difference for the central catheter tip location. Elective removals and adverse events were not significant between groups; however, poor positioning was related to adverse events. Conclusions: between the two methods analyzed, the modified measurement obtained better results in the proper catheter tip positioning and, consequently, less risk to patients.

Background and aim: Malposition of peripherally inserted central catheters placed at the bedside is a well-recognized phenomenon. We report the success rate of the placement of peripherally inserted central catheters with ultrasound guidance for tip positioning and describe the knacks and pitfalls. Materials and methods: We retrospectively reviewed the medical case charts of 954 patients who received peripherally inserted central catheter procedure. Patient clinical data included success rate of puncture, detection rate of tip malposition with ultrasonography, adjustment rate after X-ray, and success rate of peripherally inserted central catheter placement. Results: The success rate of puncture was 100% (954/954). Detection rate of tip malposition with ultrasonography was 82.1% (78/95). The success rate of ultrasound-guided tip navigation was 98.2% (937/954). The success rate of ultrasound-guided tip location was 98.0% (935/954). Adjustment rate after X-ray was 1.79% (17/952). The final success rate of peripherally inserted central catheter placement was 99.8% (952/954). Conclusion: Ultrasound guidance for puncturing and tip positioning is a promising option for the placement of peripherally inserted central catheters. Ultrasound guidance could dispense with radiation exposure and the transfer of patients to the X-ray department.

Objective: Peripherally inserted central catheters are a popular means of obtaining central venous access in critically ill patients. However, there is limited data regarding the rapidity of the peripherally inserted central catheter procedure in the presence of acute illness or obesity, both of which may impede central venous catheter placement. We aimed to determine the feasibility, safety, and duration of peripherally inserted central catheter placement in critically ill patients, including obese patients and patients in shock. Methods: This retrospective cohort study was performed using data on 55 peripherally inserted central catheters placed in a 30-bed multidisciplinary intensive care unit in Mayo Clinic Hospital, Phoenix, Arizona. Information on the time required to complete each step of the peripherally inserted central catheter procedure, associated complications, and patient characteristics was obtained from a prospectively assembled internal quality assurance database created through random convenience sampling. Results: The Median Procedure Time, beginning with the first needle puncture and ending when the procedure is complete, was 14 (interquartile range: 9–20) min. Neither critical illness nor obesity resulted in a statistically significant increase in the time required to complete the peripherally inserted central catheter procedure. Three (5.5%) minor complications were observed. Conclusion: Critical illness and obesity do not delay the acquisition of vascular access when placing a peripherally inserted central catheter. Concerns of delayed vascular access in critically ill patients should not deter a physician from selecting a peripherally inserted central catheter to provide vascular access when it would otherwise be appropriate.

Usual Position

Peripherally inserted central catheters are usually inserted in supine patients. What should we do when facing a patient who cannot tolerate this position? In this article, we are describing a particularly difficult patient: not only supine decubitus was intolerable to her but lying on the side was unbearable, too. That is why, to manage a patient who required a central access but could not tolerate the usual position for placing it, we tried to do that in prone position.

Indications For Use

ABSTRACT Objective: to assess the use of peripherally inserted central catheters regarding the neonate’s profile, indications for use, and catheterized vein; the relation between the number of puncture attempts and vein; and assessment of the catheter tip position. Method: documentary, descriptive, retrospective, quantitative study, developed in a tertiary maternity hospital in Ceará. A total of 3,005 PICC insertion formularies was included and 1,583 were excluded due to incomplete data, with a convenience sampling of 1,422 insertions being obtained. Results: There were 1,200 (84.4%) newborns with gestational age below 37 weeks; 781 (54.9%) males; Apgar score above 7 in the first (628–44.2%) and fifth minutes (1,085–76.3%); and weight between 1,000 and 1,499 grams on the day of insertion (417–29.3%). Antibiotic therapy had 1,155–53.8% indications for insertion; the basilic was the most used vein (485–34.1%); basilic and cephalic veins had lower median puncture attempts and 1,124–79% insertions were centrally positioned. Conclusion: The results of this research highlight the continuous need to improve technical-scientific knowledge to qualify actions in neonatology.

I am writing concerning an article titled “Neonatal Peripherally Inserted Central Catheters: Recommendations for Prevention of Insertion and Postinsertion Complications,” published in Vol. 27, No. 4 (July/August 2008), pages 245– 257. Of concern are Figures 3 and 4 on page 253 titled securing the catheter with adhesive skin closure strips and looping the catheter. The instructions and pictures demonstrate how to secure the catheter using skin closure strips and show the strips placed over the catheter. This is of great concern. The manufacturer’s recommendations on BD L-Cath System state the following on page 8 line 26, “Secure the catheter and dress the site with a sterile dressing. Tapes and securing devices should never be applied directly to the non-protected catheter.” This caution is echoed in the article titled “Tiny Patients, Tiny Dressings: A Guide to Neonatal PICC Dressing Change,” published in Advances in Neonatal Care, Vol. 8, No. 3, pages 141–162. The author states the following, “Some hospitals use skin closure strips. If these are utilized, manufacturer’s recommendations should be followed, and they should never be placed directly overlying the catheter to avoid catheter breakage and embolism.” The author supports this statement with the following reference, Frey AM. PICC complications in neonates and children. Journal of Vascular Access Devices. 1999: 17–26. It is clear that skin closure strips used to secure the peripherally inserted central catheter pose great risk and must never be applied directly over the catheter. Thank you for sharing this important information with your readers.

In view of the complexity of the conventional simulation calculation method of three-dimensional flow field for the reservoir, and to analysis of the change of the reservoir’s flow field in flood period, in this paper, based on the unsteady flow numerical calculation, the simulation method for three-dimensional space flow velocity field of the reservoir in flood period was studied and applied to the Wenyuhe Reservoir. First refining the actual extraction of grid, and then having an unsteady flow numerical calculation for the reservoir, finally through layering and stripping the grid, three-dimensional space flow velocity field the reservoir on the condition of unsteady flow has been studied. The results showed that the reservoir velocity along the flow direction is becoming smaller, and surface velocity is fast; with the flow increase gradually, the unsteady flow has a great effect on the flow field of the reservoir’s concave bank. The grid can at will encryption, so the calculation precision can be effectively controlled and the process of simulation is easy to be programmed. The research results can simplify the complexity of the reservoir for three-dimensional numerical simulation, and up to providing theoretical support for reservoir flood control.

Introduction: Transthoracic echocardiography with bubble test is an accurate, reproducible, and safe technique to verify the location of the tip of the central venous catheter. The aim of this study is to confirm the effectiveness of this method for tip location in patients with atrial arrhythmia. Methods: Transthoracic echocardiography with bubble test was adopted as a method of tip location in patients with atrial arrhythmia requiring central venous catheter. If bubbles were evident in the right atrium in less than 2 s after simple saline injection, tip placement was assumed as correct. In cases of uncertain visualization of the bubble effect, the test was repeated injecting a saline–air mixture. Tip location was also assessed by post-procedural chest X-ray. Results: In 42 patients with no evident P-wave at the electrocardiography, we placed 34 centrally inserted central catheters and 8 peripherally inserted central catheters. Transthoracic echocardiography with bubble test detected two centrally inserted central catheter malpositions. In four patients with peripherally inserted central catheter, transthoracic echocardiography with bubble test was positive only when repeated with the saline–air mixture. When the transthoracic echocardiography was positive, the mean (±standard deviation) time for onset of the bubble effect was 0.89 ± 0.33 s in patients with centrally inserted central catheter and 1.1 ± 0.20 s in those with peripherally inserted central catheter; such time difference was not statistically significant (p > 0.05). Conclusion: Tip location of central venous catheter by transthoracic echocardiography with bubble test is feasible, safe, and accurate in patients with atrial arrhythmia. This method can also be applied in peripherally inserted central catheters; however, further studies may be needed to confirm its use in this type of catheters.
