Summary
This scoping review synthesizes evidence on peripheral vascular catheter (PVC) flushing practices. It aims to map research on PVC flushing to improve patient safety and reduce healthcare costs associated with complications.
Area of Science:
- Medical Devices
- Nursing Practice
- Evidence Synthesis
Background:
- Peripheral vascular catheters (PVCs) are essential for intravenous therapies but prone to complications.
- Complications like occlusion, infection, and thrombosis increase patient morbidity and healthcare costs.
- Current evidence on PVC flushing practices is fragmented, hindering clear clinical guidance.
Purpose of the Study:
- To systematically explore and synthesize existing research on peripheral vascular catheter flushing.
- To map the scope, methodologies, and outcomes of studies investigating PVC flushing.
- To identify gaps in the evidence base for improved clinical practice and future research.
Main Methods:
- Adherence to Joanna Briggs Institute (JBI) methodology for systematic reviews.
- Comprehensive search strategy across major databases (Embase, Web of Science, PubMed, Scopus, CINAHL), registries, and grey literature up to May 2024.
- Screening and data extraction by two independent reviewers, following PRISMA-ScR guidelines.
Main Results:
- Initial search identified 3021 records for screening after duplicate removal.
- Data extraction will focus on scope, methodologies, and reported outcomes of PVC flushing studies.
- Results will be structured using the Patterns, Advances, Gaps, Evidence for practice, and Research recommendations (PAGER) framework.
Conclusions:
- This scoping review will provide a comprehensive overview of PVC flushing research.
- Findings will inform clinical practice, highlight areas for improvement, and guide future research directions.
- The synthesis aims to enhance patient safety and optimize the use of peripheral vascular catheters.

97
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

01:25Suctioning the Oropharyngeal Airway
172
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...
