烧伤患者创面水分丢失量实用计算法

A practical method for the calculation of wound water loss in burn patients

目的探讨更为简便、实用的烧伤创面水分丢失量计算方法。方法85例成年烧伤患者,烧伤面积均在50%TBSA以上,测算休克期后(伤后3d)患者24hWWL(ml·%TBSA-1·kg-1)=[入量(ml/24h)-尿量(ml/24h)-500ml]÷实际创面面积(%TBSA)÷体重(kg),同时与其他公式(Davies、S.M.S.P、Lamke)及手掌测量法进行比较。结果烧伤患者休克期后每日WWL为(0.9±0.1)ml·%TBSA-1·kg-1,几种计算公式结果相近。体重60kg左右患者的WWL计算方法可以进一步简化为手掌法。结论利用推荐公式及手掌法进行WWL计算,方法简单便于记忆,适合在临床应用。

Objective To evaluate a calculating method of wound water loss(WWL) in hospitalized burn patients. Methods Eighty-five adult burn patients with total burn area over 50% were enrolled in the study. The WWL formula after shock stage (after 3rd postburn day) was given as: WWL (ml/%/kg/24 h)=[input (ml/24 h)-urine output (ml/24 h)-500 ml] ÷actual burn wound area(%) ÷body weight (kg). The result was compared with that determined by other formulas such as Davies, S.M.S.P and Lamke and palm rule. Results The calculated daily WWL in burn patients after shock stage was found out to be 0.9±0.1 ml/%/ kg/24 h by this method. This figure is comparable with that calculated by several different methods. Palm rule could be simply applied in the patients with body weight around 60 kg. Conclusion This method and palm rule were proved to be simple and practical for the calculation of WWL in burn patients, which could be applied in clinical work.
