Kenichiro Yagi, BS, RVT, VTS (ECC, SAIM), shares his favorite hack: You can place a sampling catheter in a patient without needing to place a central line.
By placing an intravenous catheter in a peripheral vessel, the lateral saphenous vein for example, then using an intracath fed through the catheter, you can reach a major vessel that will allow you to obtain accurate samples. This method saves time by not having to place a jugular catheter and still allows for accurate results to be obtained.
