We use a double lumen UAC and give fluids/TPN/meds via 1 port and use the other port for continuous blood pressure monitoring and lab collections. We also give blood through the UAC via the monitoring port in the VLBW infants. We don't start a PIV if they have a UAC in place unless they are a bigger baby needing a transfusion or have a med that is incompatible with the maintenance fluids or TPN. Once the patient is stable a PICC line is placed and the UAC is D/C'd. We have been very successful with this practice and it saves the patient a great deal of sticks.
