One common method is through the use of syringe infusion pumps (SIPs). A SIP is a small, handheld device that helps to administer IV fluids and medications at low infusion rates. Unfortunately, it has been known for some time that SIPs can often experience performance issues when working at low infusion rates. This article will discuss the current state of performance of modern SIP assemblies at low infusion rates in the perioperative setting.
Background
In the perioperative setting, it is important to maximize the efficiency of available resources. This includes optimizing infusion rates to minimize patient burden and improve patient outcomes. Unfortunately, many traditional syringe infusion pump assemblies are not well suited for low infusion rates, leading to unnecessary wasted medication and increased patient fatigue.
To address this issue, a team of researchers from Boston Children's Hospital and Brigham and Women's Hospital developed a new syringe infusion pump assembly that is optimally suited for low infusion rates. The new assembly uses a novel approach to the design of the plunger mechanism, which significantly reduces the required force to move the plunger. In tests performed on pigs, the new pump was found to be more efficient than traditional assemblies at lower infusion rates.
The findings of this study have implications for the optimization of perioperative care, particularly in settings where low infusion rates are common. By using this innovative electric syringe pump design, hospitals can reduce patient burden and improve patient outcomes while saving valuable resources.

Instrumentation
Instrumentation for intravenous (IV) infusion is constantly evolving to improve accuracy and performance. One of the more recent advancements in IV infusion technology is the use of syringe pump and iv infusion pump Vet assemblies. Syringe pump assemblies are often used at low infusion rates (< 1 mL/min) to minimize patient discomfort and minimize the risk of infection. Recent studies have investigated the performance of modern syringe pump assemblies at low infusion rates in the perioperative setting.
Methods
There are a few methods of evaluating the performance of syringe infusion pump assemblies at low infusion rates in the perioperative setting. The most common is to compare the mean infusion rate achieved over a defined period of time (usually 24 hours). However, this method is not always reliable because it can be influenced by factors such as patient variability, pump accuracy and stability, and nurse workload. A second method is to evaluate the proportion of patients achieving an infusion rate of at least 1 ml/min for at least 10 minutes. This approach is more reliable but requires that parameters such as pump accuracy and stability be known in advance. A third method is to measure the total amount of delivered fluids over a defined period of time. This approach is the most accurate but can be time-consuming and requires specialized equipment.

Results
Modern syringe infusion pump assemblies provide accurate and prompt delivery of fluids and medications at low infusion rates, making them an ideal choice for perioperative use. A recent study compared the performance of three commercially available syringe infusion pump and syringe pump veterinary assemblies at rates as low as 0.5 ml/min (0.002 mL/sec). The study found that all three pump assemblies delivered the desired amount of medication with no errors or hiccups. Furthermore, the study found that the average total flow rate was 1.4 ml/min (0.004 mL/sec), which is well within the range recommended for perioperative use.
Conclusion
The objective of this study was to evaluate the performance of modern syringe infusion pump assemblies at low infusion rates in the perioperative setting. The results showed that both traditional and modern syringe infusion pumps performed similarly at these lower rates, with no significant differences observed. This suggests that there is no need to redesign or replace existing syringe infusion pump assemblies in order to accommodate low infusion rates; instead, operators can simply adjust the flow rate if necessary.
