How to Put on a Tourniquet When Drawing Blood or Starting an IV
As a nurse, you’ll be putting tourniquets on patients’ arms for tasks like drawing blood, and the best way to do so is with the rubber bands that come with IV gauge kits or blood drawing kits; they’re lightweight and flexible, and they make a simple but effective compression.
How to Put a Tourniquet on Your Patient
First, I always like to explain what I’m doing, so I usually tell them that I’m going to put a tourniquet on their arm to help with whatever procedure I’m doing. Next, stretch the tourniquet band behind their arm, making sure to get a good stretch, as this will help compress their arm. Finally, loop the tourniquet around their arm and cross the two ends as if you were going to tie a knot.
How do you use a tourniquet step by step?
Now that that’s out of the way, here’s how to apply a tourniquet:
- Wrap the limb in a rope, belt, or bra that is at least two inches closer to the body than the wound.
- Place your desired torsion device on top of the overhand knot.
- Twist the torsion device in one direction until bleeding stops.
Where do you put the tourniquet when drawing blood?
Tourniquet application, believe it or not, is one of the most important steps in proper venipuncture. Place a tourniquet 3 to 4 in (7.6 to 10.2 cm) above the site, tying it tight enough to slow venous blood flow but loose enough to avoid obstructing arterial blood flow.
What is the purpose of tourniquet application in venipuncture?
The use of a tourniquet to improve venous filling, increase vein distention, and aid vein location is common.
What is the best angle for needle insertion during venipuncture?
To avoid passing through the vein, the World Health Organization recommends keeping the insertion angle at 30 degrees or less (15 is ideal).
When should a tourniquet be applied?
Only use a tourniquet if bleeding is uncontrollable and life is at risk. 1 Wrap a 2-3u201d strip of material around a long bone between the wound and the heart, about 2u201d from the edge of the wound.
What is the immediate step to be followed when tourniquet is applied?
Place the new, distal tourniquet 5 cm from the highest wound and apply it tightly. Release the proximal tourniquet while keeping an eye on the wound. If bleeding persists, tighten the distal tourniquet until bleeding stops.
What can I use for a tourniquet?
Consider using pens or pencils, sticks, or spoons as a windlass, as long as they are strong enough to hold the tourniquet and can be secured in place. Place your windlass on the knot you’ve made, then tie the loose ends of the tourniquet around it with another square knot.
How long should a tourniquet stay in place during a blood draw?
Release the tourniquet BEFORE withdrawing the needle once enough blood has been collected; some guidelines recommend removing the tourniquet as soon as blood flow has been established, and never after it has been in place for two minutes or more.
How tight should a tourniquet be?
To prevent localised nerve and tissue damage, a tourniquet should be at least 4cm wide, and it must be applied tightly enough to stop the bleeding; if it is not, it can actually increase blood loss. It may be necessary to apply multiple tourniquets to completely stop bleeding.
What is the first step in routine blood collection?
The first step in the collection process is to positively identify the patient using two methods: ask the patient to state and spell his or her name, as well as give you his or her birth date.
What is the most important thing for an effective tourniquet?
We’ve looked at what not to do with a tourniquet, but if one is required, keep the following principles in mind: The tourniquet must completely stop arterial (blood flow moving away from the heart) blood flow, and larger limbs require more pressure to be maintained.
What is tourniquet time?
Most clinicians limit tourniquet inflation to 1.5 to 2 hours, with techniques like hourly tourniquet release for 10 minutes, cooling of the affected limb, and alternating dual cuffs helping to reduce the risk of injury.
What is the maximum time a tourniquet should be left on?
By 6 hours, muscle damage is nearly complete, necessitating amputation. Several studies have been conducted to determine the maximum duration of tourniquet use before complications, with the general conclusion that a tourniquet can be left in place for up to 2 hours with little risk of permanent ischaemic injury.
