Effect of skin expansion by B-mode ultrasound with modified Seldinger technique on preventing puncture site bleeding after the catheterization in breast cancer patients

Abstract

Objective To explore the effect of skin expansion by B-mode ultrasound with modified Seldinger technique (MST) on preventing puncture site bleeding after the catheterization in breast cancer patients. Methods One hundred chemotherapy breast cancer patients who need to be catheterized PICC were recruited to participate in a randomised controlled trial in Tianjin Medical University Cancer Institute & Hospital, China. Fifty were assigned to the experimental group (using Intra-thecal intubation sheath), and 50 were assigned to the control group (expansion skin by scalpel). The two groups used modified Seldinger technique (MST) during the procedure of ultrasound guided PICC insertion, Patients errhysis and average frequency of dressing-change were collected for 1 week since catheterization to compare the effects of the two methods. Results Patients' errhysis and average frequency of dressing-change were (0.491±0.241) ml, (1.060±0.239) times in the experimental group, significantly lower than (2.903±1.046) ml, (3.500±0.646) times of the control group (t=15.889, 25.049, P < 0.01). Conclusions This study showed a lower incidence errhysis of skin expansion by intra-thecal intubation sheath used for PICC insertion. This technique deserved clinic application in PICC.
