During March 2003 to May 2004, a total of 105 neonates were enrolled. The baseline characteristics comparing neonates with and without LNS are presented in Table 2. There were no significant difference in gestational age, birth weight, gender, age of sepsis workup and utilization of CVCs and duration of total parenteral nutrition. The utilization of CVCs other than UVC (umbilical arterial catheter, PICC and Boviac) also was not significantly different between LNS and no LNS group. Only the utilization rate of UVC was significantly different between both groups (8.6% in No-LNS group vs 25.7% in LNS group, P=0.02).
