截瘫并发褥疮封闭负压吸引细菌培养分析

目的分析封闭负压吸引治疗对截瘫Ⅲ～Ⅳ度褥疮伤口内菌群的影响.方法：回顾性分析24例截瘫合并骶尾粗隆部和/或足踝部褥疮患者的临床资料,18例经封闭负压吸引治疗,6例常规治疗,对褥疮伤口进行细菌培养和药物敏感试验.结果：初次培养最常见感染菌群为大肠杆菌,其次为铜绿假单孢菌、致病性葡萄球菌、鲍曼不动杆菌,混合感染较多见;2组对菌群的影响无明显差异（P=0.157）.结论：封闭负压吸引治疗截瘫褥疮,并不能有效清除截瘫伤口中的致病菌增殖.

Clinical Analysis of Germiculture from Vacuum Sealing Drainage Treatment for Pressure Ulcers inParaplegia Patients

Objective To investigate how colony counts changed when （vacuum sealing drainage VSD） ther-apy was used in paraplegia patients. Methods Twenty four cases of pressure ulcer wounds in paraplegia pa-tients were retrospectively reviewed of them, 18 cases received VSD and 6 cases were treated with conventionaltherapy .During the treatment, samples for germ culture were taken from the center of the wound or from thedrained exudate by using a scalpel. Results VSD had a similar effect on the bacterial load as conventionaltreatment（P=0.157）.The bacteria identified in the pressure ulcers included Escherichia coli,coagulase-positiveStaphylococcus, Pseudomonas, coagulase-negative Staphylococcus, Proteus, Staphylococcus epidermis, and Staph-ylococcus aureus,et al. Conclusion The VSD can promote wound healing,but VSD cannot reduce wound bac-teria in pressure ulcer wounds in paraplegia patients.
