Figure 6: Pericardiocentesis Preparation. An over-the-needle catheter (Angiocath), stop-cock, extension set, syringe and green-top test tube are shown as follows. (a) Prepare the Angiocath using a scalpel blade to create two extra holes on opposite sites (indicated by the arrows) towards the end of the catheter. (b) Ensure that all edges are smooth and holes sufficiently far apart to avoid the catheter tip from breaking off.
