摘要
严重烧伤之后，组织渗出明显；水肿严重，组织液压也应随之上升。为进一步了解这一问题的实质，我们采用ZHY－1型组织液压测量仪，对24例重度以上的烧伤病人的组织液压进行了测定，除常规地与正常对照组进行比较以外，还对重度与特重度病人不同部位、不同时间的组织液压进行了比较分析。结果发现：渗出期间重度与特重度病人的伤区与非伤区组织液压均高于对照组，特重组高于重度组，烧伤区高于非烧伤区，相互之间均显示非常显著，性差异。到了回收期末，不论特重组还是重度组，他们的伤区组织液压都随水肿消退至大幅度下降改变，但都未降至正常水平，说明回吸收期未组织间隙中仍有一定液体稽留。3例小腿国环形焦痂导致局部组织液压上升，在未超过35cmH2O之前及时进行了焦痂切开减张手术，肢体组织液压迅速下降，远端血运也随之改善。
Exudation of tissue fluid and edema are often ap-parently seen after burn injury. Tissue fluid pressure isotten at a high leveI. Tissue fluid pressure of 14 pa-tients with severe burn and 10 patients with extremelysevere burn was measured in our hospital, using aType - ZHY tissue fluid pressometer and the resultswere compared with that of the normal control. Withinthe exudation period, 48 hours after burn, the subcu-taneous tissue fluid pressure at the burned area of thesevereIy and extremely severely burned patients wererespectiveIy 19. 59 ±10. 48 and 8. 75±2. 27 cmH2O,and at the non - injuried area were respectively 5. 27±2. 37 and 2. 79±1.04 cmH2O, and were higher thanthat of the normal control (0. 07 1±1. 16 cmH2O). Thedifference between the normal control and injured patients, between injured area and non-injured area ofthe burn patients and between the severely burnedand extemely severety burned patients had very greatstatistical significance (P<0.01). At the end of therecovery period, 7 days after burn, tissue fluid pres-sure at the injured area lowered obviously but re-mained higher than normal. This implied that 7 daysafter burn, there was still retention of fluid in the in-terstitial space. 3 patients had circular eschar in legswere subjected to incision to reduce the pressure un-der the eschar. The results were satisfactory. Thetissue fluid pressure under the eschar was kept below35 cmH2O.
