Summary
Continuous peripheral nerve blockade uses infusion pumps for pain relief after surgery. This study evaluated the accuracy and consistency of elastomeric pumps, crucial for safe and effective postoperative analgesia.
Area of Science:
- Anesthesiology
- Biomedical Engineering
- Pharmacology
Background:
- Continuous peripheral nerve blockade is a common technique for postoperative pain management.
- The efficacy and safety of these blocks depend on the reliable performance of infusion pumps.
- Understanding infusion pump characteristics is vital for selecting appropriate devices for clinical use.
Purpose of the Study:
- To assess the accuracy and consistency of flow rates delivered by current elastomeric infusion pumps.
- To provide data that aids clinicians in choosing the most suitable pumps for peripheral nerve blockade.
Main Methods:
- Investigated the accuracy and consistency of several elastomeric infusion pumps.
- Employed a methodology similar to previously published studies on portable infusion pump accuracy.
Main Results:
- Flow rate accuracy and consistency data were collected for multiple elastomeric pumps.
- The performance profiles of these pumps were analyzed.
Conclusions:
- Elastomeric pump performance varies, impacting their suitability for continuous peripheral nerve blockade.
- Accurate pump data is essential for optimizing postoperative analgesia and patient safety.

01:13Pumped Concrete
1.5K
Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

01:30ATP Driven Pumps III: V-type Pumps
3.8K
V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of a few specialized eukaryotic cells, and some prokaryotes. They are also known as the V1Vo-ATPase, that couple ATP hydrolysis to transport protons against a concentration gradient.
The peripheral or cytosolic V1 domain with eight subunits is involved in ATP hydrolysis. The integral or transmembrane V0 domain containing at least five subunits...

01:34ATP Driven Pumps II: P-type Pumps
5.1K
The P-type pumps are a large family of integral membrane transporter ATPases. They are divided into five major types based on substrate specificity, from I to V.
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...

2.0K
In High-Performance Liquid Chromatography (HPLC), the elution process is critical to the separation of analytes and the quality of chromatographic results. Elution describes how compounds move through the column and separate based on their interactions with the mobile and stationary phases. This process determines the resolution, peak shape, and retention times in the chromatogram, which are essential for identifying and quantifying components in complex mixtures. Understanding the elution...

03:37Uncertainty in Measurement: Accuracy and Precision
93.8K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.
