Life span of intravenous cannulas in a neonatal intensive care unit

Area of Science:

• Neonatal intensive care
• Vascular access devices
• Clinical practice research

Background:

• Peripheral intravenous cannulas are essential for neonatal intensive care unit (NICU) therapy.
• Assessing complication rates and factors influencing cannula longevity is crucial for patient safety and resource management.

Purpose of the Study:

• To prospectively survey peripheral intravenous cannula use in a NICU.
• To determine the rate of complications associated with intravenous cannula therapy.
• To identify factors influencing the functional lifespan of intravenous cannulas in neonates.

Main Methods:

• Prospective survey of 199 peripheral intravenous cannulas inserted in 69 neonates over three months.
• Data collection on patient demographics, fluid administration, medication types, and cannula complications.
• Statistical analysis to identify factors affecting cannula lifespan and complication rates.

Main Results:

• A low rate of significant infiltrations (1%) was observed across over 5000 hours of intravenous therapy.
• Most studied factors (weight, age, fluid type/rate, medication type) did not significantly impact cannula lifespan.
• Pancuronium bromide was associated with a significant increase in cannula functional lifespan, extending it from 30 to 50 hours.

Conclusions:

• Clinically significant complications from peripheral intravenous cannula therapy in the NICU setting are infrequent.
• Cannula lifespan is generally not affected by common clinical variables in neonates.
• Pancuronium bromide demonstrates a potential to prolong the functional life of peripheral intravenous cannulas in this population.
