目的探讨深部热疗在大肠癌深静脉置管术后导管相关感染的作用。方法收集接受深静脉置管术的大肠癌患者301例次,干预组151例次,接受深部热疗;对照组150例次,术后不接受深部热疗,观察穿刺部位导管相关感染及机械性静脉炎的发生情况。结果干预组导管相关机械性静脉炎22例次,发生率为14.6%,无导管相关感染;观察组导管相关机械性静脉炎52例次,发生率为34.7%,导管相关感染2例,发生率为1.3%。两组组间比较,P<0.05,差异有统计学意义。干预组静脉炎Ⅰ级、Ⅱ级、Ⅲ级和IV级的发生率分别为2.6%、7.3%、4.7%和0.0%,而对照组分别为4.0%、17.2%、12.2%和1.3%,各级发生率间的差异均有统计学意义(P<0.05)。结论深部热疗是预防大肠癌化疗深静脉插管术后导管相关感染及机械性静脉炎的理想方法。
Objective To investigate the effect of deep hyperthermia on catheter-related infections after deep venous catheterization in colorectal cancer. Methods A total of 301 patients with colorectal cancer undergoing deep vein catheterization were enrolled in this study. 151 cases were treated with deep hyperthermia in the intervention group and 150 cases in the control group. Postoperative deep hyperthermia was not observed, and catheter-related infection at the puncture site and mechanical The incidence of phlebitis. Results There were 22 cases of catheter-related mechanical phlebitis in the intervention group, with a incidence rate of 14.6%. There was no catheter-related infection in the intervention group. The incidence of catheter-related mechanical phlebitis was 52.7% in the observation group, 34.7% in the observation group and 2 in the catheter- 1.3%. Between the two groups, P <0.05, the difference was statistically significant. The incidences of phlebitis grade I, II, III and IV in the intervention group were 2.6%, 7.3%, 4.7% and 0.0%, respectively, compared with 4.0%, 17.2%, 12.2% and 1.3% in the control group The differences between the two groups were statistically significant (P <0.05). Conclusion Deep hyperthermia is an ideal method to prevent catheter-related infection and mechanical phlebitis after deep vein catheterization of colorectal cancer.
