摘要:
目的 比较银离子敷料与普通无菌敷料2种不同敷料对腹部手术不良切口愈合的影响.方法 选取西安交通大学第二附属医院普外科行腹部手术患者94例,用双盲法分成2组,银离子敷料组49例,普通无菌敷料组45例.观察2组患者分别应用2种不同敷料换药后的切口愈合情况,观察指标包括换药次数、愈合时间、疼痛程度、细菌培养阳性率、瘢痕愈合发生率.结果 银离子敷料组和普通无菌敷料换药组患者在性别、年龄、切口长度、切口类型和切口愈合不良类型方面差异无统计学意义(均P>0.05);经过2种敷料换药治疗后,银离子敷料组换药次数为(6.52±1.52)次、切口愈合时间为(16.34±5.96)d,均少于普通无菌敷料组换药次数(8.74±2.35)次、切口愈合时间(23.32±8.32)d;疼痛程度评分(4.13±1.01)分,也低于普通无菌敷料组疼痛程度(6.54±0.95)分,2组比较差异有统计学意义(t=5.482、4.704、11.890,均P0.05);after two wound dressings change treatment, the wound dressing change times and incision healing timeof the silver-coated dressing group was (6.52 ± 1.52) times and (16.34 ± 5.96) days, which were less than those of the general aseptic dressing group, which were (8.74 ± 2.35) times and (23.32 ± 8.32) days; and the pain severity (NRS) scored 4.13 ± 1.01, which was lower than that of general aseptic dressing group (6.54 ± 0.95), with significant difference between two groups (t=5.482, 4.704, 11.890, P < 0.05). The bacterial culture positive rates of the silver-coated dressing group was 60.00% (21/35), which was higher than that of the general aseptic dressing group, 23.33%(7/30), the difference was statistically significant (P<0.01);at the same time, the scar healing cases was 4 in the silver-coated dressing group, which was less than 11 cases in the general aseptic dressing group. The difference was statistically significant (P < 0.05). Conclusions The silver-coated wound dressing method is better than the general aseptic wound dressing, and has obvious advantages in the treatment of abdominal poor healing incision. The silver-coated wound dressing can promote the healing of incision, reduce scar healing, shorten the hospitalization time, reduce the suffering of patients.
