可充气式气囊加压敷贴的研制及加压效果影响因素的病例对照研究

摘要

目的:比较可充气式加压敷贴与传统加压包扎对外科手术伤口愈合的影响.方法:将2009年5月至2010年2月入院接受手术治疗的50例闭合性股骨干骨折患者分为两组,每组25例.其中A组为试验组:年龄38～60岁,平均(55.1±9.5)岁;男13例,女12例;车祸伤18例,高处坠落伤6例,意外跌伤1例;术后伤口采用气囊加压敷贴包扎.B组为对照组:年龄40～65岁,平均(56.5±9.2)岁;男15例,女10例;车祸伤13例,高处坠落伤6例,意外跌伤6例;采用传统环扎加压包扎.观察术后12 h两组伤口引流量、患肢末梢血氧饱和度及患者满意率,以评价气囊式加压敷贴的加压及止血效果.结果:A组患者术后12 h伤口引流量为(77.5±4.6)ml,低于同时间点B组术后伤口引流量(94.3±3.8)ml0;术后12、24 hA组患者末梢血氧饱和度分别为(98.3±1.1)%、(98.9±0.8)%,均高于B组(96.5±0.4)%及(97.0±0.3)%;术后患者满意率A组高于B组.结论:与环扎加压包扎比较,可充气式加压敷贴的加压止血效果无明显差异,但对患肢末梢血运的影响较小,且术后患者的不适感减轻.%Objective :To compare the influence on the postoperative wound healing between inflatable pressure applicator and traditional pressure dressing. Methods:From May 2009 to February 2010,50 patients with closed femoral shaft fractures were randomly divided into group A and group B,with 25 patients in each group. There were 13 males and 12 females in group A,ranging in age from 38 to 60 years,with an average of (55.1±9.5) years;of them,road accident was in 18 cases,fall from heigh was in 6 cases,accidental falling injury was in 1 case. There were 15 males and 10 females in group B,ranging in age from 40 to 65 years, with an average of (56.5±9.2) years;of them, road accident was in 13 cases, fall from heigh was in 6 cases,accidental falling injury was in 6 cases. There was no significant difference between two groups in clinical data. The postoperative wounds of group A were binded with dressing of inflatable pressure applicator;and of group B with traditional pressure dressing. Volume of drainage at 12 h after operation ,saturation of blood oxygen at 12,24 h after operation,satisfactory rate of patients were compared between two groups. Results: Postoperative volume of drainage in group A was lower than that of group B,respectively was (77.5±4.6), (94.3±3.8) ml. Saturation of blood oxygen at 12 ,24 h after operation in A group was respectively(98.3±l.l )％, (98.9±0.8)％ ,and in group B was respectively (96.5±0.4)％, ( 97.0±0.3)％ ;there was significant difference between two groups at the same time. Satisfactory rate of patients in A group was better than that of group B. Conclusion:Inflatable pressure applicator can obviously pressurize and stop bleeding for postoperative wounds, but no affect on peripheral blood supply and can improve discomfort of patients.
