Abstract：Objective To analyze the learning curve of B ultrasound-guided peripherally inserted central catheter(PICC)placement in infants.Methods The clinical data of 115 cases of B ultrasound-guided PICC placement operated by the same group of operators from January, 2010 to June 2016 were retrospectively analyzed. According to the operation time sequence, 155 cases were divided into two groups, A and B, and the B group was subdivided into 6 subgroups(I~VI Subgroup). The operation time, the success rate of first puncture, the complication rate and the failure rate were compared between groups.Results There was a significant difference in operation time between group A and group B(P<0.05). The operation time was longer in II subgroup than that in III, IV, V and VI subgroup, respectively(P<0.05). There was no significant difference in operation time among III, IV, V and VI subgroup(P>0.05). According to line diagram and box plot, the operation time was maintained at the level of 60 min after 35 operations. There was no significant difference in one-time success rate of puncture, complication rate and failure rate of PICC placement among different groups(P>0.05).Conclusion In B ultrasound-guided PICC placement in infants, it is required to complete the operation of about 35 cases to complete the stage of learning curve. The operation time can be maintained at about 60min.
