【摘要】 目的探讨复苏补液对重烧伤儿童休克期足甲襞微循环（ＦＮＭ）障碍的改善作用。方法用ＷＸ—７５３Ｂ型微循环显微镜及其图像处理系统监测３０例重烧伤儿童休克期复苏补液过程的ＦＮＭ变化，观测时相分别是入院时、补液后１、２、３、４、５、２０、４０小时。本组儿童平均年龄５．５７±２．７０岁，平均烧伤面积３６.０４ ％±１６.９０％。结果补液前ＦＮＭ管襻数减少、长度缩短、直径减小、血流速度缓慢、红细胞聚集和襻周渗出等。经复苏补液（晶胶型）后，管襻数、长度和直径在补液后２～３小时恢复正常，血流速度、红细胞聚集逐渐恢复，襻周渗出则随补液治疗逐渐加重。结论重烧伤儿童休克早期存在严重的微循环障碍，而复苏补液（晶胶型）对烧伤休克微循环障碍有明显的改善作用，但补液不能减少毛细血管周围渗出。更多还原

【Abstract】 objective To study the effect of treatment with fluid infusion on foot nailfold microcirculation (FNM) disorder during shock period of severely burned children. Methods 30 cases of severely burned children (average burned area: 36.04±16.09%) were observed about the changes of FNM with microcirculation microscope and image analysis system (WX-753B) before fluid infusion and 1,2, 3,4, 5, 20, 40 hours after fluid infusion respectively during shock period. Results The decreased numbers,the shortened length and the lessened diameter of the loop and the slowed blood flow rate,aggregation and permeability of RBC were found before fluid infusion and returned to normal 2-3 hours after in number,length and diameters of the loop.The blood flow rate and aggregation of RBC recovered gradually and permeability around the loop aggravates with treatment with fluid infusion. Conclusion There is serious disorder of microcirculation in the early stage during shock in severely burned children. The fluid infusion has an improved effect on microcirculation disorder of the burned in shock period,but can not reduce the capillary permeability.更多还原
