【摘要】：目的探讨高温高湿环境下肢体火器伤后细菌入血时间及伤道和血液中细菌种类。方法将犬随机分为高温高湿(HHE)组和常温常湿(NE)组,于火器伤后0、4、6、8、12、24h进行体温测量、伤道分泌物和血液的细菌培养及菌群分析。结果HHE组动物体温较NE组升高早,且持续高热;血液中出现细菌的时间:NE组为伤后12h,HHE组为伤后8h;菌群分析结果:两组弹道局部分泌物中均为表面菌群;血液中NE组只有表面菌群,HHE组除表面菌群外还有肠道菌群。结论高温高湿环境下火器伤后体温升高明显,细菌入血时间提前,肠道细菌容易入血,处理更应强调早期使用广谱抗生素。
[Abstract]:Objective to study the bacterial entry time and the bacteria species in the wound tract and blood after firearm injury in high temperature and high humidity. Methods Dogs were randomly divided into high temperature and high humidity (he) group and normothermic (NE) group. The body temperature was measured for 24 hours after firearm injury, and bacterial culture and bacteriological analysis of wound secretion and blood were carried out. Results the body temperature of the HHE group was earlier than that of the NE group, and it continued to be high fever, the time of presence of bacteria in the blood of the ne group was 12 hours after injury and 8 hours after the injury, and the results of microflora analysis showed that the surface bacteria were found in the local ballistic secretion of the two groups. In the NE group, only the surface microflora and intestinal microflora were found in the HHE group. Conclusion under the condition of high temperature and high humidity, the temperature of firearm wound is increased obviously, the time of bacteria entering blood is advanced, the bacteria of intestinal tract is easy to enter blood, and the treatment should emphasize the early use of broad-spectrum antibiotics.
