Key Parts are parts of the device/s that must remain aseptic throughout the clinical procedures.Hand hygiene is performed to protect the patient from organisms which may enter their key sites or key parts during a procedure. Hands – Effective hand hygiene is an essential component of Aseptic Technique. Is crucial for preventing microorganisms from entering the patient It is a set of practices designed to reduce contamination and protect the patient from infection during invasive procedures such as PIVC insertion and maintenance. Therefore, unlike sterile techniques, aseptic techniquesĪre possible and can be achieved in typical hospital and community settings. Aseptic technique – aims to prevent pathogenic microorganisms in sufficient quantity to cause infection, from being introduced to susceptible sites by hands, surfaces and equipment.PIVCs allow for the administration of medications, fluids and/or blood products. Intravenous catheter (PIVC) is a thin plastic tube inserted into a vein using a needle. Nurses who are deemed competent in IV insertion could continue to insert PIVC in consultation with NUM/CSN’s. For information related to insertion of PIVC, please refer to intravenous access guideline (). The aim of this guideline is to provide an outline of the ongoing maintenance and management of the PIVC for patients in hospital, outpatient, and home healthcare settings. They are primarily used for therapeutic purposes such as administration of medications, fluids, and blood products.īy The Royal Children's Hospital, Melbourne This suggests 16-cm triple-lumen CVCs can be used safely.Peripheral intravenous catheters (PIVCs) are the most commonly used intravenous devices in hospitalised paediatric patients. No CVCs failed under dynamic loading with injection of contrast at flow rates (4.5 and 7 mL/s) high enough to support computed tomographic angiography. During dynamic testing the mean peak pressures at 7 mL/s was 81.1 PSI (95% CI 73-89.2 PSI). PSI at burst during static testing was 184.2 PSI (95% confidence interval 174.3-194.1 PSI). Pressures were recorded throughout injection.ĭuring static testing, 6/7 CVCs burst at the distal lumen where the glue was applied, the remaining CVC burst proximal to the hub. Dynamic pressure testing was done with the remaining catheters, with radio-contrast injected through the unoccluded distal lumen at flow rates of 4.5 mL/s, then 7 mL/s. The CVC was then placed into a 10-cm deep water bath at 37☌ to simulate in vivo conditions and water was injected until catheter rupture. Half the CVCs (n = 7) were subjected to static testing, where the distal lumen was occluded with the guidewire and super glue at the distal end of the catheter. We gathered 16-cm long triple-lumen CVCs (n = 14) from patients with an average dwell time of 5.2 days (☒.7 days). The CVC might rupture at high flow rates, resulting in CVC fragmentation and embolization or contrast extravasation.The objective of this study is to determine the pressure required to burst a CVC under static load and compare this to the pressure generated by injection of contrast at high flow rates (dynamic load) through the distal (16-g) lumen of a triple-lumen CVC. Patients undergoing computed tomographic angiography require injection of contrast at high flow rates (4.5 mL/s), often CVC access is not used due to safety concerns. Central venous catheter (CVC) access is commonplace in intensive care units.
