Every person in his entire life has to deal with taking medications. In most cases, drugs are prescribed in tablets, capsules, suppositories and powders. It is in this form that the patient is comfortable to take them on their own. However, there are more serious and serious situations when the doctor prescribes the introduction of the drug into a vein. This is what will be discussed later. You will learn the intravenous injection algorithm. The features of such a procedure will be described below. It is also worth saying how intravenous drip injection is given. The algorithm will be described later.
Types of injections into a vein
The algorithm for intravenous injection may vary slightly, it all depends on the type of injection. Quite often, a blood test is prescribed to patients. The material is taken from a vein with a special pumping device or a regular syringe.
Injections are also quite popular. In this case, a specific drug is administered during intravenous injection. This scheme allows the drug to spread faster throughout the body and begin its action.
The injection may take the form of a dropper. In this case, the setting algorithm will also have its own characteristics. If such manipulation is performed very often, then a special catheter is inserted into the patient’s vein to avoid permanent puncture of the skin. In this case, the infusion of the drug is performed in a different way. Consider the algorithm for introducing intravenous injection.
Blood sampling
What is the algorithm for intravenous injection during analysis? Quite often, patients have to donate blood for research. This allows you to more accurately diagnose and prescribe the correct and timely treatment. How to act in this case?
- First of all, you need to wash your hands. If it is not possible to carry out a hygienic procedure, then it is worth using sterile gloves or lubricate the palms and fingers with an antibacterial gel. Next, take the piston device and open the plastic bag. It is with such a device that it is easiest to take a blood sample.
- The next step is to prepare the patient. Take a tourniquet or special strap. Put it on your hand and bring it to the forearm, drag the selected area of the hand. Prepare a towel or pillow folded several times, place the device under the elbow of a person. Remember that while taking blood from a vein, the patient must sit or lie down. Ask the person to make several clenches of a fist and pump up a vein.
- Take a cotton swab or a bandage soaked in alcohol and wipe the area into which you intend to insert the needle. The direction of the swab should be from the periphery to the center of the injection. In the right hand, take the piston with the needle, and with your left hand, probe the venous trunks and select the most swollen one.
- With a gentle but sure movement, insert the needle into the vein. As soon as you feel empty, remove the cap from the capsule and draw the right amount of blood.
- Remove the needle from the vein, before this remove the tourniquet. Place a sterile dressing on the injection site and ask the patient to bend the arm.
Intravenous injection
The intravenous drug injection algorithm is somewhat similar to the blood sampling scheme. However, these manipulations are still different from each other. It is worth noting that the introduction of medicines into the bloodstream should be entrusted to professionals. Only in this case you have a guarantee that the manipulation will be carried out correctly.
- Disinfect hands or wear sterile gloves. Remove the syringe from the package and open the ampoules with the medicine. If necessary, mix the medicines and transfer them to the injection device.
- Place a tourniquet or a pull-down strap on the patient’s forearm. Ask to pump the vein with your fist.
- Wipe the area of the selected channel with an alcohol composition from the bottom up. Use your left hand finger to pull the elbow skin down. In the right hand, place the syringe with the cut up and pierce the skin with a vein. Insert the needle a few millimeters and pull the syringe plunger towards you. If his cavity begins to fill with blood, then this indicates that the needle is in the vein.
- Further, the intravenous injection algorithm involves the removal of the tourniquet. Also ask the patient to relax the hand and open the fist. Slowly, with the thumb of your right hand, begin to press the piston. Introduce the medicine and make sure that there are no air bubbles in it.
- Remove the syringe from the vein at the end of the injection. Press the wound with cotton and apply a bandage.
How to put a dropper?
The intravenous (drip) injection algorithm is very similar to a syringe injection. The differences are only in the introduction of the needle and the method of delivery of the drug.
- Wash your hands and open the bag with the system. To set up a dropper, you will need a special tower. It is on it that the jars of medicine are located.
- Prepare the system by inserting one of its ends into an ampoule. Hang the drug on the boom. Next, place a tourniquet on the patient’s arm and wipe the selected vein towards the shoulder.
- Open the system and check for air in it. Also make sure that the medicine is delivered correctly. Close the system and take the needle into your right hand.
- With your left thumb, press the vein trunk from above, so you lock the trunk. Pierce the skin, and then gently insert the needle into the vein one centimeter. Remember that the cut should be located with the hole up, and the needle should be parallel to the vessel. Remove the tourniquet from the patient’s arm.
- Stick the patch on the base of the syringe to fix it and open the dropper. When the procedure is over, remove the needle and clamp the wound.
Catheter placement
You know the algorithm for performing intravenous injection. However, it is not always performed once. If you need to put such injections several times a day, then you should use a catheter - such a device allows you not to pierce the skin constantly. Such manipulation needs to be done only once.
- Clean your hands and remove the catheter from the individual packaging. Place a tourniquet on the forearm and disinfect the vein.
- Insert the catheter needle under the skin at an angle of 75 degrees. After that, change direction and smooth the angle to 15 degrees. In this position, push the needle a few millimeters forward.
- Next, pierce the vein and insert the full-length needle into it. In this position, lock the catheter. This can be done using special fabric patches.
- If you need to put an injection or a dropper, you just need to open a suitable hole and inject the medicine. The catheter may be in the vein for a long time. After removing it, it is worth putting ice on the wound.
Algorithm for performing intravenous injection with blood
Some drugs require prior mixing with blood. In this case, the algorithm for intravenous injection will be as follows.
- Wash your hands and carry out preparatory procedures. Place the tourniquet on the patient’s arm and wipe the vein with an alcohol compound.
- Pierce the skin and vein, feeling empty. Pull the syringe plunger toward you and draw two to five milliliters of blood. After that, remove the tourniquet and enter the contents of the syringe.
- Remove the needle and bandage.
Special situations
Often, an intravenous injection inflates a vessel. In this case, you must immediately stop the manipulation and remove the needle. Wait for the blood to clot and try the procedure again.
If a bruise forms after the injection, then it is worthwhile to apply an iodine grid or use absorbable ointments.
Finally…
Now you know the algorithm for the action of intravenous injection. If you are assigned such procedures, then you should contact the professionals. Self-intervention in the bloodstream can end up pretty disastrous.
