Objective To explore effect of different postures for PICC intubation through basilic vein in very low birth weight infants. Methods Eighty infants from Oct. 2013 to Sep. 2014 with PICC via basilic vein were set as the control group in which traditional method of preventing catheter displacement was applied, another 80 cases from Oct. 2014 to Sep. 2015 were divided to the observation group. And improved method was applied in the experiment group besides the traditional method. The ectopic occurrence rates of the two groups were compared. Result The ectopic rate of PICC catheters in the observation group was significantly lower than that of the control group (P<0.05). Conclusion When the catheter tip reaches the shoulder of the very low birth weight infants, the method of raising their upper limbs slightly to the head can reduce the ectopic incidence of catheters and thereby improve the success rate of PICC intubation.
