Abstract:
Objective:To explore the safety, economic benefits, and clinical application effect of the new practical patent open window central venous catheter combination dressing (Patent No.ZL 202121652858.8).Methods:From October 2022 to October 2023, a randomized controlled trial was conducted. A total of 120 tumor patients in Yunnan Cancer Hospital with indwelling central venous catheters who met the inclusion and exclusion criteria were randomly divided into three groups at a ratio of 1∶1∶1 with random digit table, with 40 patients in each group: control group 1, control group 2, and the experimental group. In control group 1, Smith & Nephew IV 3000 dressing was used, in control group 2, 3M transparent dressing was used; and in the experimental group, the self - developed fenestrated central venous catheter combined dressing by the researchers was used for catheter maintenance. The skin surface bacterial colonization, the occurrence of medical adhesive-related skin injuries, catheter maintenance time, and maintenance costs were compared among the three groups.Results:In control group 1, there were 21 males and 19 females, with an average age of (51.53 ± 12.01) years. In control group 2, there were 22 males and 18 females, with an average age of (54.00 ± 11.03) years. In the experimental group, there were 19 males and 21 females, with an average age of (53.60 ± 9.41) years. During the 72 - hour observation period, 1, 3, and 2 cases of bacterial colonization occurred in control group 1, control group 2, and the experimental group respectively, and there was no significant difference among the three groups ( χ2 = 1.10, P = 0.577). No medical adhesive - related skin injury occurred in the experimental group, and there was a significant difference compared with the 4 cases in control group 2 ( χ2 = 4.21, P = 0.040). The average catheter maintenance time and maintenance cost in the experimental group were (15.20 ± 1.56) minutes and (8.11 ± 1.35) yuan respectively. Compared with (21.05 ± 3.31) minutes and (13.16 ± 1.03) yuan in control group 1, the differences were statistically significant ( t = 5.85, 5.05, both P<0.001). Compared with (21.08 ± 3.00) minutes and (15.17 ± 1.63) yuan in control group 2, the differences were also statistically significant ( t = 5.88, 7.06, both P<0.001). Conclusions:The open-window central venous catheter combination dressing designed in this study can effectively reduce the incidence of medical adhesive-related skin injury, and also has a better role in saving maintenance time and reducing maintenance costs, especially for patients who need repeated dressing changes at the puncture point for treatment with the advantages of, convenience, economy, speed, firm fixation and safety.
