To prevent complications, what should be avoided when selecting a site for IV insertion?

Using varicose veins for IV insertion should be avoided due to several reasons related to patient safety and the effectiveness of venous access. Varicose veins are often enlarged, twisted, and may have compromised structural integrity. This can lead to several complications such as difficulty in the insertion process, increased risk of infiltration or phlebitis, and potential for thrombosis. Moreover, the altered blood flow in varicose veins makes it difficult to achieve reliable venous access, and using them can cause discomfort and worsen the condition of the vein.

In contrast, identifying a good site for IV insertion involves selecting veins that are healthy and capable of providing stable access for the duration of the treatment. This is why choosing the most visible vein, the non-dominant hand, and selecting distal veins are seen as preferable practices. These options facilitate easier insertion, better flow dynamics, and less discomfort for the patient.
