Pain where a cannula was inserted is usually due to common, minor issues like bruising or vein irritation that typically fade within a week. However, persistent or severe pain could indicate a complication like phlebitis, infiltration, or nerve injury, which requires immediate medical attention.
When the cannula has been taken out, the place where it has been may feel slightly bruised. This sensation can last for up to one week and is quite normal. The dressing which is put over the site after removal can usually be taken off within a couple of hours.
IV Site Hurts After 2 to 3 Weeks
If it persists longer, for 2-3 weeks, it is usually a sign of a condition known as thrombophlebitis, which is when a blood clot forms and causes a blockage in the vein.
Symptoms of IV line infection include:
IV Needle Contact With Nerves and IV Insertion Injuries
Signs of nerve injury may manifest as prolonged pain, burning sensations, and potentially numbness or loss of function in the affected area. In severe cases, nerve injuries may necessitate long-term pain management interventions.
The signs of nerve damage include the following:
The cannula (the flexible tube) may puncture the vein and the medicine then goes into the surrounding tissue, or the same vein may be used multiple times, which weakens it.
Swelling, heat or redness at the site of your cannula or redness spreading over your arm. If this happens there may be some bleeding from the site DO NOT PANIC! Apply firm pressure over the site using a clean cloth or kitchen towel, elevating the arm until it stops bleeding. Do not attempt to reinsert the cannula.
Recovery from nerve damage may take only weeks or a year or more. Some patients, however, may sustain lifelong damage depending on the severity of the needle stick to the nerve. To avoid injury to peripheral nerves when inserting i.v. catheters, a few recommendations should be followed.
The most common complication is called phlebitis (an inflamed vein that can be identified by swelling and redness around cannula site).
Call your doctor or nurse advice line now or seek immediate medical care if: You have signs of infection, such as: Increased pain, swelling, warmth, or redness or any change in colour. Reddish streaks leading from the area.
A blown vein is a vein that's mildly injured during a blood draw or IV placement. Symptoms include bruising, swelling and discomfort around your vein. While a blown vein isn't serious, it needs about 10 to 12 days to heal before your provider can use it again.
Symptoms
An injection of lidocaine 1 % was estimated to be −12.97 (95 % CI −15.71, −10.24) points as painful, an injection of saline with benzyl alcohol −16.32 (95 % CI −25.44, −7.20) points as painful, ethyl chloride spay −14.00 (95 % CI −17.12, −10.88) points as painful and EMLA® cream −23.50 (95 % CI −26.27, −20.73) points ...
Superficial thrombophlebitis is an inflammation of a vein just below the surface of the skin, which results from a blood clot. This condition may occur after recently using an IV line, or after trauma to the vein. Some symptoms can include pain and tenderness along the vein and hardening and feeling cord-like.
Twenty-eight of the 50 patients found the DOH to be a more painful cannulation site than that of the ACF site. Fourteen of the 50 patients found the ACF site to be a more painful cannulation site. Eight patients found no difference in terms of pain between the two cannulation sites.
Nerves can be damaged by needles used to place a cannula ('a drip') into a vein or artery. What are the most common peripheral nerve injuries? The ulnar nerve runs in the arm down to the fourth and fifth fingers.
10 Signs You May Be Suffering from Nerve Pain
Mistakes involving a cannula — whether it's inserted incorrectly, left in too long, or not monitored properly — can lead to serious injuries, infections, or even life-threatening complications. If you've suffered harm due to poor cannula care in a hospital or medical setting, you may be entitled to compensation.
During the IV procedure, tell your medical team right way if you feel pain at or around your IV site. After the procedure, if you have continued redness and swelling, the IV site may be infected. Infection is a serious complication and needs to be addressed immediately.
In addition to these visible signs, there are also physical sensations that can indicate a collapsed vein: Pain or Tenderness: The injection site may be painful, even when not being used. No Blood Return: When attempting to inject, you may not see any blood flowing back into the syringe, indicating a blockage.
Minor vein damage such as a blown vein can usually repair itself in 10-12 days. Major vein regrowth, however, can take months up to several years.
Urgent advice: Ask for an urgent GP appointment or get help from NHS 111 if you have:
Superficial thrombophlebitis, is often called phlebitis. It is the term for an inflamed vein near the surface of the skin caused by a blood clot. Phlebitis causes painful, hard lumps underneath the skin and redness of the skin but it is not usually serious.
If they leak outside the vein it is called infiltration. You may have noticed pain, stinging, swelling or other changes to the skin at the site of the cannula, or the nurse may have noticed that the drug isn't flowing into the vein easily.
