Port-a-cath or a peripherally inserted central catheter (PICC) Medications can be given into the vein through a port-a-cath or a peripherally inserted central catheter (PICC). These have a portable pump that delivers the medication. Some people get the medication continuously. Others can push a button to release an extra dose of medication for added relief (called patient-controlled analgesia). Still others have both continuous medication and the option to give themselves extra doses.
