Bicarbonate的補法

Bicarbonate的補法計算公式如下：

1. HCO3 space (Bicarb Vd) = [0.4 + (2.6 / [HCO3] ) ] x lean body weight (in Kg)
2. HCO3 deficit = HCO3 space x HCO3 deficit per liter

Since the distribution of bicarbonate is about 50% of lean body weight, ... serum concentration to normal can be estimated as follows:

1. HCO3~ deficit (mEq) = 0.5 x lean body wt (kg) x (desired [HCO3-] - measured [HCO3-])
2. Bicarbonate deficit = 0.2 x weight (kg) x base deficit (mEq/L).

Bicarbonate deficit: The amount of bicarbonate req'd to correct a metabolic acidosis can be estimated from the following formula:

1. Volume of distribution (Vd) = Total body weight (kg) x [0.4 + (2.4/[HCO3-])
2. (Deficit) mEq of NaHCO3 = Vd x target change in [HCO3-]

水星窩蟲：

1. (24-HCO3-)/2=Rolikan支數，1/2 Push; 1/2 Slowly drip
2. Rolikan 1支 約=4.68# Sodium Bicarbonate 300mg/tab

 

藥品：
針劑：Sod. bicarbonate濃度7%，每一支20mL中含有16.67mEq

口服：Sodium Bicarbonate (元宙) 300mg/tab=3.56 mEq

(16# =4.8g=57mEq Na, 57 mEq HCO3-)
