we allow tube transport in our facility to only specific areas: 1) Emergency Department, 2) CVR (post cardiothoracic surgery recovery unit), and 3) critical care units. A tube transport request is submitted with all the appropriate identifiers and a copy of the physician's order indicating the unit is to be given immediately. the request and a copy of the physician's order are kept in the BB and we haven't decided how long we'll keep them yet. the tube transport request also includes an area indicating the name of the nurse initiating the request, who shipped it, and there is documentation of a phone call confirming receipt of the unit and by whom. confirmation should be made within 5' of transport. only packed RBCs and plasma products can be sent via tube transport since the vacuum and somewhat physically violent passage in the pneumatics activates the platelets in our experience. no significant hemolysis was detected during validation for the PRBCs. we were actually surprised, the blood bank staff was actually expecting the pneumatics would rupture the blood bags or hemolyze them.
