In the RBC： Hb or HbO2 / HHb or HHbO2 In the plasma： protein or HCO3－ /H protein or HHCO3－ effects of kidney and lung on pH regulation (參考：獸醫(yī)解剖生理學(xué) (中 ) ) 五。 Clinical Review 1. 臨床脫水病例治療之考量 (1)脫水之程度 → 減輕之體重 → 失去之水分：下痢後之體液量 (2)正常總 Na量與下痢後之總 Na量：估算損失之 Na量 (3)下痢前後之 Na差值估算 ECF量與 ICF量 ： 估算兩者之損失量 治療設(shè)計 (mEq/L) Na K＋ Ca＋＋ Cl－ HCO3－ lactated Ringer’s soln. 130 4 3 109 28 multisolRinger’s soln. 140 5 0 98 50 % saline 154 0 0 154 0 plasmaLyte A 140 5 0 96 50 五 。 Clinical Review 2.
