There are two techniques to cannulate the vein.
An introducer needle is used in one technique, and the guidewire is inserted directly into the hand and subsequently into the vein.
The other technique consists of an angiocatheter over an introducer needle.
The angiocath is a sterile, peripheral, non-needle type intravenous (Jelco) catheter.
Once the vessel is cannulated, the angiocatheter is inserted into the vein, and the needle is withdrawn.
The advantage is that this can provide a more stable venous access during guidewire insertion and requires little threading skill.
The angiocatheter is also helpful in manometry to ensure that the cannula is within the vein (rather than the artery) in situations where ultrasound cannot be used, such as subclavian midline placement.
Indications of angiocath
Angiocath is indicated in peripheral intravenous therapy for medium and short-term infusions.
This is a single-use disposable device that comes in 14G, 16G, 18G, 20G, 22G, and 24G gauges.
It is shown in boxes with 50 units packed per unit in a blister, sterile, and ready for use.
Product Description and Advantages
Angiocath is a peripheral catheter made up of:
- Siliconized needle with bi-angled and triplet bevel: facilitates puncture and reduces tissue trauma.
- A catheter (or cannula) in Vialon biomaterial: offers incomparable performance in punch during the stay in the vein and minimizes the appearance of phlebitis. Ensures a perfect view through Radio X.
- Protector of the needle/catheter assembly: guarantees the integrity of the needle until the moment of use; its anatomical format allows removal with just one of the hands.
- Luer-Lok connector, translucent, color-coded, and with fixation slots: allows a secure connection to the equipment, facilitates identification of the gauge, and favors fixation through the surgical site.
- Reflux chamber in «Crystal»: offers a fast stitch and allows quick visualization of the blood reflux at puncture. The camera has a design that improves the grip.
- Reflux chamber lid with microgrooves.
Angiocath use precautions
Angiocath replacement is recommended at least every 72 to 96 hours in adults. In pediatric patients and neonates, it is recommended to leave the catheter in place until intravenous therapy is concluded unless complications such as phlebitis or infiltration occur.
The general precautions to be taken when using an angiocath telco are as follows:
- The needle should never be reinserted into the catheter as it is a single-use product. It must be destroyed after use.
- Any accident with hands should be reported immediately, and the area should be treated according to protocol.
- Contaminated needles can cause serious illnesses like hepatitis, AIDS, and other infectious diseases.
- Discard after use all the material in place for potentially contaminated materials, in suitable collectors for piercing and sharp objects, by local legislation and waste management procedures in the health area.
- Do not use scissors in or near the insertion area, not the packaging must be violated; it should be used only if the packaging is intact.
- Store in a dry and clean place.
Instructions for use
- Health professionals must be trained in venipuncture and be aware of the inherent dangers.
- Aseptic technique should be used; proper skin preparation and continued protection of the area are essential. Standard precautions should be observed in all patients.
- Select the angiocatheter introducer needle.
- You start with the center line as usual. Wash hands and place implements on sterile clothing.
- Prepare the patient’s skin, creating a barren field, the patient is anesthetized, and the central line kit is prepared.
- The needle shield should be removed, the catheter inspected, and the catheter tip fitted to the needle.
- The catheter is inserted into the vein as usual and continued slowly.
- Good traction on the skin is maintained during the insertion of the catheter.
- When the vessel is cannulated with the angiocatheter introducer needle, it can be confirmed with a flash of venous blood and ultrasound.
- By visualizing blood reflux, the angle of the catheter about the skin is decreased, and the catheter needle assembly is advanced 0.5 cm into the vein.
- The reflux chamber is held firmly in place, and the catheter is advanced into the vessel.
- The introducer needle is firmly grasped, and the catheter is passed over the hand until the center of the catheter is flush with the skin.
- Holding the barrel of the catheter, the introducer needle is carefully withdrawn, and the instrument is immediately discarded in the appropriate container (resistant to pinholes and fluid loss).
- The guidewire is threaded, and once the wire is threaded, the angiocath is removed.
- The catheter is fixed using the appropriate method, and the local area is treated according to the protocol.
- Continue the rest of the procedure as usual.
