Extravasation refers to the leakage of fluids from a vein into the surrounding tissues.
That is the correct spelling of the medical term "cannulation" (using a drainage tube).
The term 'cannulation' is used to denote a tube or cannula being inserted into the body. Cannulation is used to administer medication, or to withdraw fluid from the body.
The superficial veins of the upper extremities are best for cannulation.
Cannulation is the medical procedure of inserting a thin, flexible tube called a cannula into a vein, typically to deliver fluids, medications, or for blood sampling.
Extravasation comes from the term extravate, which means to force or squeeze something out. Extravasation is most commonly used as a medical term as it relates to urology, epidemiology and other fields where this type of action takes place within the human body.

Big petechiae are caused by the extravasation of blood into the surrounding tissue due to a break in the blood vessels. This can be a result of trauma, certain medical conditions, or medications that affect the blood's clotting ability. It is important to determine the underlying cause of the extravasation to guide appropriate treatment.

Jaundice is characterized by the yellowing of the skin and eyes due to elevated levels of bilirubin in the blood. Blood extravasation, which refers to the leakage of blood from vessels into surrounding tissues, can lead to the breakdown of red blood cells. This process releases hemoglobin, which is subsequently converted to bilirubin. Therefore, conditions causing blood extravasation can contribute to jaundice by increasing bilirubin production from the breakdown of hemoglobin.
Extravasation can cause tissue necrosis.
I've found some pretty good free tutorial videos at www.simmed.com. Quite a range of tutorials including venepuncture, cannulation, drug injections etc. Their products seem pretty useful too.
Extravasation occurs when a medication or solution being administered intravenously leaks into the surrounding tissue rather than staying within the vein. This can happen due to various reasons such as damaged veins, incorrect positioning of the IV catheter, or high pressure during infusion. It is important to monitor for signs of extravasation, such as swelling, pain, or tissue damage, and take immediate action to minimize potential harm to the patient.
