Which blood collection needle type is often preferred for geriatric patients?

The preference for 23-gauge needles when collecting blood from geriatric patients is primarily due to the need to minimize discomfort. As individuals age, their veins may become more fragile, and they may experience thinner skin and reduced tissue elasticity. This can lead to increased sensitivity and discomfort during procedures such as venipuncture.

Using a smaller gauge needle, such as a 23-gauge, helps to reduce the diameter of the needle, which can result in less trauma to the vein and surrounding tissue. Consequently, this can help alleviate pain and anxiety for geriatric patients who may already be apprehensive about needles or have a low pain threshold.

While other gauge sizes do have their specific applications and benefits, the focus on minimizing discomfort in geriatric patients makes the 23-gauge option particularly suitable for this demographic.
