2. Fig. 1 Graphical representation of interventions.
The open arrows represent the times that the IV tobramycin was given every 12h (Q12h) on Day 1 and Day 2. The smaller arrows are the times at which the serum was collected. The first dose of IV tobramycin was considered time 0 each day. The TIS was given between 5 and 9h after the third dose (morning dose on Day 2).

Minimum concentration (trough) and elimination rate constant over time of serum tobramycin.
A: minimum concentration (trough) of serum tobramycin. The minimum concentration (Cmin) was calculated for each patient on Day 1 and again on Day 2. The graph represents a line for each patient drawn from the Cmin calculated on Day 1 to the Cmin calculated on Day 2. Solid black lines indicate patients whose Cmin increased on Day 2 when compared to Day 1. For our center, if the Cmin is over 1μg/mL, the patient's interval of IV tobramycin will be increased to achieve a Cmin <1μg/mL. The broken black line indicates a Cmin of <1μg/mL.
B: elimination rate constant over time.
This graph represents a line drawn from the elimination rate constant (ke) calculated on Day 1 (no TIS) to the ke calculated on Day 2 (after TIS) for each patient. Dotted lines indicate patients whose ke decreased on Day 2 when compared to Day 1.
