Efficacy or effect
acidosis
Uricosuric during drug addiction (limited to drugs that promote the urinary excretion by increasing the pH)
Nausea and vomiting and dizziness associated with the following diseases or conditions
Motion sickness, Meniere's syndrome, and other inner ear disorders
Acute urticaria
The acidosis generally normal dose is calculated by the following equation, and intravenous injection.
The required amount (mEq) = lack the amount of base (Base Deficit mEq / L) × 0.2 × body weight (kg)
In the case of Meylon intravenous 8.4%
The required amount (mL) = lack the amount of base (Base Deficit mEq / L) × 0.2 × body weight (kg)
Excretion promotion at the time of the drug addiction, the nausea and vomiting and dizziness, as well as acute urticaria associated with motion sickness, etc., usually adult once 12~60mEq as sodium hydrogen carbonate (1~5g: this drug 12~60mL) intravenous injection to.
In addition, it will be increased or decreased depending on the patient's age and symptoms in either case.
Careful administration
Cardiac arrest of a patient 1) [carbon dioxide accumulates, there is a fear that becomes the incentive of intracellular acidosis expression]
Patients with congestive heart failure, and a burden to the heart from increasing the patient 'circulating blood volume of severe hypertension, there is a risk that symptoms worse]
Patients with renal failure [moisture, prone to overdose of sodium, there is a possibility that the symptoms worse]
A peripheral and pulmonary edema is likely to be exacerbated by the patient [edema.]
Patients with preeclampsia[moisture, it is easy to fall into an overdose of sodium, there is a risk that worsen the pregnancy toxemia. ]
Of hypocalcemia patient[there is a possibility that the symptoms worse]
