Objective To explore the application effect of ultrasound-guided placement of modified midline catheter in critically ill patients. Methods From March 2022 to May 2023, 82 patients with severe diseases admitted to our hospital were selected as the research objects. According to the principle of random grouping, they were divided into the management group and the reference group. The management group placed the modified midline catheter under the guidance of ultrasound, while the management group used the central venous catheter to place the catheter. The effect of catheterization was compared between the two groups. Results The success rate of first catheterization in the management group was higher than that in the reference group (P<0.05); The incidence of complications in the management group was higher than that in the reference group (P<0.05); The indwelling time of the management group was longer than that of the reference group (P<0.05). Conclusion The placement of a modified midline catheter under ultrasound guidance in critically ill patients is of great significance for improving the quality of intravenous infusion and is worth promoting.
