What are the advantages and disadvantages of syringe?
An advantage of the syringe method is that blood appears in the hub when the vein has been entered. A disadvantage of the syringe method is that there is the potential for needle stick when depositing blood into the collection tube.
What are the disadvantages of a syringe?
The volume of syringe used limits the fluid dispensing volume. Excessive resistance may lead to the build-up of pressure and eventual failure of the syringe pump. The flow rate during the transient period cannot be known without flow sensors.
What are the advantages of using a syringe driver?
What are the advantages to using a syringe driver?
- Control of multiple symptoms.
- Maintaining a constant level of medication, no peaks and troughs.
- Avoids the need for 2-4 hourly injections and invasive treatment.
- Patients can remain mobile and independent with a driver in place.
What are the advantages and disadvantages of performing venipuncture?
Skin Puncture or Venipuncture? Pros & Cons, Part 2
| Pros | Cons |
|---|---|
| faster than obtaining capillary blood | increased potential for hematoma formation |
| less likely to be contaminated by tissue fluid | requires greater patient stability |
| less likely to be hemolyzed | multiple venipunctures precipitate iatrogenic anemia |
What are the disadvantages of intravenous infusion pumps?
Disadvantages:
- The pressure produced can cause extravasation/infiltration of intravenous fluids.
- The alarm will sound when the pressure reaches high levels eg 2000mm/Hg.
- The occlusion alarm is proportional to flow rate, ie if a low flow rate is set, the alarm may take up to an hour to sound.
What are the advantages of intravenous infusion pumps?
Infusion pumps offer significant advantages over manual administration of fluids, including the ability to deliver fluids in very small volumes, and the ability to deliver fluids at precisely programmed rates or automated intervals.
What are disadvantages of skin puncture?
Fainting or feeling lightheaded. Infection (a slight risk any time the skin is broken) Scarring (occurs when there have been multiple punctures in the same area) Calcified nodules (sometimes occurs in infants, but usually disappear by 30 months of age)
What are the disadvantages of arterial blood collection?
Collection of arterial blood has its disadvantages. It is more difficult to obtain than venous or capillary blood sample, it is more painful for the patient and it can be potentially dangerous, if the correct procedure is not followed (1).

Skin Puncture or Venipuncture? Pros & Cons, Part 2
| Pros | Cons |
|---|---|
| requires less precision | specimen clotting more likely |
| minimizes iatrogenic anemia | more painful to the patient |
| patient injury less likely | yields smaller volumes of blood |
| decreased risk of accidental needlestick | potential for tissue fluid contamination |
