What Researchers Did
Researchers assessed the performance of a BBraun Perfusor Space syringe driver, including pump flow accuracy and occlusion alarm function, under hyperbaric conditions using three different 50 ml syringe brands.
What They Found
Syringe driver performance was highly dependent on syringe type, with two of the three 50 ml syringes demonstrating 'stiction' during pressurization. For the BBraun Omnifix 50 ml syringes at 284 kPa, flow rate differences were within the manufacturer's 10% specification, with median variations of 1.25% at 40 ml·h⁻¹ and -8.8% at 5 ml·h⁻¹. Pressurization was associated with significantly lower flow rates, while decompression led to increased rates.
What This Means for Canadian Patients
Medical professionals in Canada using syringe drivers in hyperbaric settings should be aware of potential variations in device performance depending on the syringe brand used. Careful selection of compatible syringes, such as the BBraun Omnifix, could help ensure accurate medication delivery for patients undergoing hyperbaric treatment.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
The study tested only a single device and reported flow measurements for only one syringe type due to significant stiction problems encountered with the other two brands.
