What could happen if Glucose 10% extravasates from the vein?

If glucose 10% extravasates from the vein, tissue necrosis could occur due to the hypertonic nature of the solution. When a hypertonic solution such as glucose 10% leaks into the surrounding tissue, it can cause osmotic damage. The high concentration of glucose draws water out of the surrounding cells, leading to cellular dehydration and subsequent necrosis. This can present as inflammation and damage to local tissues, which may result in complications such as ulcer formation or even more severe tissue loss if not managed appropriately.

Other possibilities, like improved glucose levels, weight gain, or headaches, are not relevant in the context of extravasation. The immediate concern is the risk of local tissue damage due to the hypertonic solution rather than systemic effects.
