Objective  To analyze the effect of peritoneal catheterization and takeover guided by color ultrasound (B-ultrasound) on the flow rate of chemotherapeutic hyperthermic intraperitoneal perfusion and control rate of ascites.

  Methods  From February 2017 to December 2019, 36 patients receiving chemotherapeutic hyperthermic intraperitoneal perfusion at Yantai Hospital of Traditional Chinese Medicine were included and assigned into the experimental and control groups according to the different methods of catheterization and takeover. Differences in the flow rate of hyperthermic in traperitoneal perfusion and control rate of ascites between the two groups were compared.

  Results  Among 36 patients, the experimental and control groups included 18 patients each. Patients in the experimental group underwent B-ultrasound-guided intraperitoneal catheterization and tube connection. The duration of high perfusion flow rate and effective flow rate after the first and third cycles of thermal perfusion were longer in the experimental group than in the control group. Additionally, the complete control rate of ascites was significantly higher in the experimental group than in the control group (66.67% vs. 44.44%, P<0.05).

  Conclusions  Through the use of B-ultrasound-guided intraperitoneal catheterization and connection, the flow rate and stability of circulatory hyperthermic perfusion and complete control rate of ascites were improved, thereby expanding the clinical application of chemotherapeutic hyperthermic intraperitoneal perfusion.
