What are the advantages of using a burette when administering IV medications to Paediatric or elderly patients?
What are the advantages of using a burette when administering IV medications to Paediatric or elderly patients?
The use of a burette allows fine control of fluid volume and avoids inadvertent over-transfusion.
What are the disadvantages of IV medication?
Disadvantages of drugs administered by IV include an inability to reverse the actions of all drugs after they have been injected. Although it is possible to reverse the actions of some drugs (e.g., opioids, anticholinergics, and benzodiazepines) through the use of specific drug antagonists, this is not always the case.
When do you use a burette?
A burette is used to dispense small volumes of liquid called aliquots, or sometimes gas, with high accuracy. It consists of a long glass tube with a valve at one end to control the flow of liquid. Burettes serve essentially the same purpose as a pipette.
Why is burette used for titration?
A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined.
What is the accuracy of a burette?
Burette (class B) – one drop from a burette has a volume of approximately 0.05 cm3. All burette readings should include 2 decimal places in which the second figure is either 0 or 5. An error of one drop in a volume of 25.00 cm3 gives a percentage error of 0.2% for each reading.
What are the types of burette?
There are three types of burette:
- Volumetric Burette. A volumetric burette is made of glass or plastic material, with a volume scale printed on the burette wall.
- Piston or Digital Burette.
- Electronic Burette.
Which solution is taken in burette?
Typically, the titrant (the known solution) is added from a burette to a known quantity of the analyte (the second solution) until the reaction is complete. Often, a visual indicator (buffer or pH solution) is used to signal the completion (end-point).
