A patient is being treated for osteomyelitis with Rocephine through their PICC. She was recently treated in the ER for an allergic reaction and the PICC line was accessed to give meds there. The patient reported that at one point, the ER nurse handled the PICC line without wearing gloves or first washing their hands. About 24-48 hrs later the patient developed a 99.5F fever for 2 days. The fever spiked to 102F on the 3rd day. The patient also had a swollen and tender cervical lymph node that developed the same time as the fever. The patient also reported extreme fatigue, headaches, and "slight warmth and burning" in the arm with the PICC during those 3 days. There was a question of whether the patient's fever was from an infected PICC line or an adverse reaction to Rocephin. An order was placed to draw blood cultures peripherally and from the PICC line.
What is the proper way to draw blood cultures from PICC line?
If the PICC line draws blood ok, is it best to draw blood into the cultures without first flushing and wasting blood?
Or is it best to first flush the PICC line and waste blood before drawing the blood cultures? Wouldnt this method flush the bactieria out of the PICC and reduce the chance of a successful culture.
