“…On the contrary, adduction of the arm will result in a smaller catheter volume and a displacement of the locking volume. Therefore the authors suggest choosing catheter material that minimises variation in catheter volume [ 18 ]. Iterative movement of locking volume and blood at the catheter tip is assumed in catheters inserted in the arm or catheters with an external part that might be pinched.…”

Flushing and locking of intravenous catheters are thought to be essential in the prevention of occlusion. The clinical sign of an occlusion is catheter malfunction and flushing is strongly recommended to ensure a well-functioning catheter. Therefore fluid dynamics, flushing techniques, and sufficient flushing volumes are important matters in adequate flushing in all catheter types. If a catheter is not in use, it is locked. For years, it has been thought that the catheter has to be filled with an anticoagulant to prevent catheter occlusion. Heparin has played a key role in locking venous catheters. However, the high number of risks associated with heparin forces us to look for alternatives. A long time ago, 0.9% sodium chloride was already introduced as locking solution in peripheral cannulas. More recently, a 0.9% sodium chloride lock has also been investigated in other types of catheters. Thrombolytic agents have also been studied as a locking solution because their antithrombotic effect was suggested as superior to heparin. Other catheter lock solutions focus on the anti-infective properties of the locks such as antibiotics and chelating agents. Still, the most effective locking solution will depend on the catheter type and the patient's condition.

“…Curving or kinking in the middle of the catheter was related to CF, occlusion, and thrombus formation in the forearm. It may be unusual to find bending or curvature in a removed catheter because the malleability of intravenous catheters has improved in recent years (18). There is an association between the materials from which catheters are made and the incidence of thrombophlebitis (19,20).…”

The risk of peripheral intravenous catheter failure varies according to the insertion site. This study examined catheter shape just after removal to evaluate the causes of catheter failure according to site. This study was a secondary analysis of previous study data. Our observational study was conducted during a 6-month period at The University of Tokyo Hospital. Participants were hospitalized adults who received infusion therapy via a short peripheral catheter. We acquired ultrasound images of blood vessels and surrounding tissues at the catheter insertion site before catheter removal and clinical images of the removed catheters. We analyzed 184 catheters from 142 participants. There were no significant differences in the catheter failure rate (29.9%) among insertion sites. Curvature in the middle of the catheter was present in 9.2% of cases; the median bend angle at the catheter base was 9.1° (range: 0.0°-68.3°). The bend angle of catheters inserted in the upper arm was significantly greater than of catheters in the forearm (p = 0.013). Catheter curvature was related to catheter failure (14.8% of failed catheters had curvature; p = 0.035) and occlusion (35.3% of occluded catheters had curvature; p = 0.008) in upper arm and forearm placements. The median distance from the elbow to the insertion site was shorter for failed catheters than for surviving catheters. To prevent catheter failure, especially occlusion resulting from catheter curvature, a catheter should be inserted at an appropriate insertion site far from the antecubital fossa.

Purpose: Various venous access devices are available, including peripheral venous lines, peripherally inserted central catheters lines, and subcutaneous port catheters. The latter provides medium-to long-term venous access and includes medical devices that can be inserted either on the chest (chest ports) or in the arm (arm ports). We report the techniques, dedicated indications, and main complications of arm port insertion using the ultrasonography (US) guidance method. Methods: Tips and tricks of percutaneous real-time US-guided vein access technique in the arm are reviewed, and a brief literature review is reported. Results: Technical feasibility is almost 99%. US guidance allows depiction of anatomic variants, reduces the number of failed attempts, and increases the technical access rate compared with venography-guided access. Comparison of arm ports to chest ports reveals a higher global complication rate. We also report typical (mechanical) complications and dedicated indications, including contraindications to chest port insertion and selected patients for whom chest ports are not possible (eg, those with breast, head, and neck cancer; obesity; cosmesis; and requiring upright position). Conclusions: Arm port insertion under US guidance is safe and effective, and has dedicated indications.
