Objective To investigate the clinical effect of ultrasound-guided circular skin dilation in patients with thrombo-cytopenia undergoing peripherally inserted central catheter(PICC).Methods A total of 88 patients with thrombocytopenia admitted to the PICC Specialist Clinic of Xiangyang First People's Hospital Affiliated to Hubei University of Medicine from May 2022 to July 2023 were selected by convenience sampling method and divided into control group(n=44)and experi-mental group(n=44)according to different skin expansion methods.The control group was treated with conventional skin expansion method,and the experimental group was treated with 360° circular skin expansion with 20 ml syringe needle.The amount of bleeding and visual analogue scale(VAS),the success rate of one-time sheath delivery,the incidence of bleeding and exudation at the puncture point 24 hours after catheterization,and the number of catheter maintenance within 7 days af-ter catheterization were compared between the two groups.Results The immediate bleeding volume of the experimental group was lower than that of the control group,with statistically significant difference(P＜0.05).The VAS score of the ex-perimental group was lower than that of the control group,with statistically significant difference(P＜0.05).The incidence of puncture point bleeding and exudation 24 hours after catheterization in the experimental group was lower than that of the control group,with statistically significant difference(P＜0.05).The number of catheter maintenance within 7 days in the experimental group was lower than that of the control group,with statistically significant difference(P＜0.05).There was no statistically significant difference in the success rate of one-time sheath delivery between the two groups(P＞0.05).Con-clusion The ring skin expansion method can help reduce the bleeding volume of patients with low platelet count and PICC catheterization,reduce the incidence of blood and fluid exudation,and relieve the pain of patients.
