Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT After peripheral intravenous (IV) access is initiated, it is important to assess and maintain the IV catheter according to institutional policies and nursing standards of practice. The regular assessment of the insertion site and the surrounding areas for signs of complications is necessary to prevent IV catheter complications, including infiltration, phlebitis, infection, extravasation, or...

A Hypertonic Saline Injection Technique for Inducing Glaucoma in Rats

2025
This video demonstrates glaucoma induction in an anesthetized rat by injecting hypertonic saline into the episcleral vein. The saline enters the trabecular meshwork via Schlemm's canal, causing tissue scarring, which blocks aqueous humor outflow and raises intraocular pressure. The elevated pressure damages retinal ganglion cells, leading to glaucoma.

Begin with a culture of Alishewanella, a Gram-negative, salt-tolerant bacterium.Next, streak the culture onto agar plates containing increasing concentrations of sodium chloride to simulate varying levels of saline stress.Overlay each plate with a layer of unsolidified medium to prevent oxygen diffusion and maintain the culture in an oxygen-limited environment.Seal and incubate the plates at an optimum temperature to support bacterial growth.During incubation, the bacterium exhibits varying...

Embryonic stages are the most susceptible to xenobiotics. Although chemical toxicity depends on salinity, no method exists to test the salinity dependence of toxicity to aquatic organisms. Here, we describe a new and high-throughput method for determining the salinity dependence of toxicity to aquatic embryos.

Saline Lavage for Sampling of the Canine Nasal Immune Microenvironment

2024
Saline nasal lavage can be used to sample the canine nasal immune microenvironment. Because the approach is relatively non-invasive and does not disrupt the nasal tissues, it can be performed serially. Cells and proteins collected from the nasal lavage technique can be processed for various laboratory analyses.
FAQs
Gentle injection creates positive pressure within the catheter lumen. When the device is used according to the correct technique, that pressure helps oppose backward movement of blood into the access device. This supports lumen patency between uses and can contribute to more dependable vascular access during ongoing medication delivery or infusion.
A pre-medication flush helps assess and prepare the access pathway before delivery, while a post-medication flush clears residual drug from the lumen. Clearing remaining medication helps reduce the chance of medication incompatibility within the device and supports delivery of the intended dose through the vascular access system.
The vascular access device and the applicable clinical protocol determine the appropriate flush volume and technique. These factors matter because devices differ in their requirements, and correct use is necessary to generate the intended pressure without applying an unsuitable approach. Clinicians should therefore follow the protocol associated with the specific access device.
When an intravenous medication or infusion is given, clinicians commonly flush the access before and after the therapy. The first flush supports preparation and assessment of the line, whereas the final flush clears residual medication or blood. The exact volume and technique remain governed by the device and clinical protocol.
A flush may be used in connection with blood sampling to help maintain the catheter or vascular access device and clear residual blood from its lumen. Used according to the relevant technique and protocol, this supports reliable access for later use. The procedure should account for the device and the clinical purpose of sampling.
Saline flushes are especially relevant whenever clinicians use an intravenous catheter or vascular access device for medication delivery, infusion, or blood sampling. Their value extends beyond clearing the lumen: appropriate use helps maintain patency, reduce medication incompatibility, and support dependable access across repeated clinical procedures.
