单位对吗?
Urinary solute excretion varies with diet. On a typical Western diet, daily excretion of sodium is -150 mmol, potassium 75 mmol, urea 400 mmol and other nonelectrolytes 50 mmol . Excretion of the 900 mOsm of solute generated by this diet in a volume of 1.5 L would result in an average Uosm of 600 mOsm/kg. Excretion of >1400 mOsm of solute daily (>1 mOsm/h) is clear evidence of a major solute diuresis [11]. Typically, in a patient with a major solute diuresis, Uosm ranges from 300 to 500 mOsm/kg, CH2O is negative and Cosm >200 mL/h. In a patient with a water diuresis, Uosm is typically <150 mOsm/kg and CH2O is positive. Mixed solute and water diureses can be present (e.g. in a patient with diabetes insipidus treated with saline infusions)
尿溶质排泄随饮食而变化。在典型的西方饮食中,钠的日排泄量约为150 mmol、钾约75 mmol、尿素约400 mmol,其他非电解质溶质约50 mmol。该西方饮食产生的900 mOsm溶质以1.5 L的尿量排出,平均Uosm为600 mOsm/kg。每天排泄溶质>1400 mOsm(>1 mOsm/h)是严重溶质利尿的明显证据。在一个严重的溶质利尿的典型病人,Uosm范围从300-500 mOsm/kg,CH2O阴性和Cosm >200 mL/h。在一个有水利尿的病人,典型的Uosm<150 mOsm/kg和CH2O是阳性。溶质和水的混合性利尿也可出现(例如,尿崩症患者用生理盐水输液治疗)。
osmolar clearance (渗透清除Cosm) and **** water clearance (游离水清除CH2O)
urea 尿素, 对吗?
1400 mOsm of solute daily (>1 mOsm/h) mOsm/h对吗?怎么感觉应该是mOsm/(kg•h)
