摘要
为了解湿。牲疗法经创面不显，队失水的变化规律，以指导临床治疗，我们用蒸发仪对25例不同湿度和面积的烧伤病人局部创面不显性失水进行了观测，结果表明：（1）烧伤后最初几天内，经创面蒸发丢失的水量要多于正常皮肤。以伤后6小时蒸发失水量最多。此后，随烧伤深度递增和伤后时间的推移趋于减少，而且保留表皮具有进一步减少蒸发水的作用。（2）自4例大面积烧伤病人（烧伤面积大于50％BSA）局部蒸发量得出，蒸发失水平均为0．71ml/h/%BSA；结合本组总的统计，提出烧伤早期可按0．4～1．2ml/h/%BSA的标准补充水分，并应根据烧伤深度及表皮脱落的情况作适当调整。（3）液化期间，实施暴露与半暴露方式用药，在阻止创面水分蒸发量上同样有效。
Abstract In order to investigate changes in invisible dehydration of burn wounds treated with MEBT, 25 patients with burns of different areas and different depths were observed. The results showed that (1). In the first few days post burn, water loss through wounds was greatly increased, as compared with normal skin, the peak of water loss was at 6 hours post burn, then tended to decline, retairied epidemis may further reduce water loss. (2). 4 patients with large area burn (over 50% TBSA) had local wound evaporation of 0. 71 ml/h/% BSA (average value). Therefore, the authors suggest that at the early stage, water supplement can be controlled at about o. 4 to 1. 2 ml/h/ %BSA. This value should be adjusted according to wound depth and the condition of the retained epidemis. (3). At liquefaction stage, MEBO can be applied in exposed or semi - exposed way, so that wound evaporation can be controlled.
