不同换药频率对混合痔术后创面感染影响的临床研究

Clinical study of impact of drug dressing frequency on postoperative wound infections in patients with mixed hemorrhoid

目的探讨不同换药频率对混合痔术后创面感染的影响,寻找混合痔术后创面最佳处理方法,以促进创口愈合。方法选取2013年1-12月混合痔手术患者517例,随机分为两组,A组254例,每天换药1次,B组263例,每天换药2次;对两组患者术后创面感染率进行比较,对其局部疼痛及水肿进行评价分析,数据采用SPSS13.0软件进行分析。结果 A组患者术后发生创面感染8例,感染率为3.15%,高于B组的1.14%;A组患者疼痛视觉模拟评分及水肿评分分别为(3.06±0.21)分和(1.95±0.10)分,高于B组的(1.35±0.11)分和(0.16±0.04)分,两组比较,差异均有统计学意义(P<0.05)。结论混合痔术后每天2次换药可以有效减少创面感染发生率,促进创面愈合,是一种较为理想的换药频率。

OBJECTIVE To explore the influence of drug dressing frequency on postoperative wound infections in patients with mixed hemorrhoid and search for the measures of treatment of wounds after the surgery so as to fa‐cilitate the wound healing .METHODS A total of 517 patients with mixed hemorrhoid who underwent the surgery from Jan 2013 to Dec 2013 were enrolled in the study and randomly divided into two groups .The group A with 254 cases was treated with drug dressing for once per day ,while the group B with 263 cases was given drug dress‐ing for twice per day .The incidence of postoperative wound infections was observed and compared between the two groups ,the local pain and status of edema were evaluated ,and the statistical analysis of data was performed with the use of SPSS 13 .0 software .RESULTS The postoperative wound infections occurred in 8 patients of the group A ,the infection rate of the group A was 3 .15% ,higher than 1 .14% of the group B .The visual pain analog scale of the group A was （3 .06 ＆#177; 0 .21）points ,higher than（1 .35 ＆#177; 0 .11）points of the group B ;the edema score of the group A was （1 .95 ＆#177; 0 .10）points ,higher than （0 .16 ＆#177; 0 .04）points of the group B ,and there was significant difference between the two groups （P〈0 .05） .CONCLUSION The frequency of drug dressing for twice per day can effectively reduce the incidence of postoperative wound infections in the patients with mixed hemorrhoid and fa‐cilitate the wound healing ,and it is an ideal drug dressing frequency .
