Comparative analysis of midline catheters of varying lengths in patients with difficult intravenous ac-cess punctures
Objective This study aimed to observe the application effectiveness of two different lengths of midline cathe-ters in short-term infusion therapy for patients with difficult intravenous access.Methods A total of 156 patients experien-cing difficult intravenous access were randomly assigned into two groups:the test group(78 cases)and the control group(78 cases).The test group received a 10 cm mini midline catheters,while the control group received a 25 cm midline cathe-ters.The study compared the total incidence of catheter-related complications,the rate of catheter extubation due to compli-cations,and the duration of catheter retention between the two groups.Results The test group exhibited a higher total inci-dence of catheter-related complications(33.33％vs.11.54％)and a higher rate of catheter extubation due to complications(17.95％vs.2.56％)compared to the control group,with statistically significant differences(x2=10.646,P=0.002;x2=10.029,P=0.003).However,there was no significant difference in the catheter retention time between the two groups(Z=0.617,P=0.537).Conclusion In patients with difficult intravenous access requiring short-term infusion thera-py,the total incidence of complications related to mini-midline catheters and the rate of catheter extubation due to complica-tions were higher than those of 25 cm midline catheters.However,there was no significant difference in the duration of catheter retention between the two groups.
