The application of novel puncture dressing in changing dressing at puncture site of drainage about seroperitoneum / 中国医学装备

ABSTRACT

Objective: To explore the differences of physicochemical properties, antibacterial effect and clinically curative effect between nano silver combined activated carbon gel dressings and traditional dressings in change dressing at puncture site of ascites drainage. Methods: 94 patients with seroperitoneum who were implemented abdominocentesis were divided into observation group (50 cases, who were applied NSAC dressing) and control group (44 cases, who were traditional dressing) as random number table. The inhibition zone method was adopted to test the actual bacteriostasis of two dressings, and the permeability, isolation function of protective screen and adhesive force of the two dressings were compared, respectively. Besides, the maximum use time, infection rate, errhysis degree, changed dressing times in 1 week and the loose situation in changing dressing at puncture site of drainage about the two dressings were compared. Results: The permeability, adhesive force, anti-invading for outside world of dressing in observation group were 3.8 times, 2 times and 1.7 times of that of control group, respectively. At the aspect of inhibition zone, the result of observation was 1.82 times of that of control group. And the maximum usage time of observation group was (8.4±1.8)d, and it was significantly higher than that of control group (5.3±1.2)d, (t=9.683, P<0.05). The difference of times of changed dressing between observation group (1.2±0.3 times) and control group (2.7±0.8 times) was statistically significant (t=-12.318, P<0.05). The loose rate, infection rate and errhysis rate of III grade of observation group (11.2%,3.33% and 2.0%) were significantly better than that of control group (29.5%, 18.2% and 15.9%) (x2=4.468, x2=4.951, x2=6.616, P<0.05). Conclusion:Compared to traditional dressing, novel nano silver conbined activated carbon gel dressings has obvious superiority in physicochemical properties, antibacterial effect and clinically curative effect, and it is worth to be extensively popularized in changing dressing for ascites drainage at puncture site.
