When should you use HCO3 therapy?

You should alkalinize the urine when you face:

• Barbiturates toxicity
• Salicylates toxicity
• Rhabdomyolysis

And you use HCO3 for Treatment of Tricyclic antidepressants toxicity, BUT not for alkalinization, it's for saturating Na channels with NaHCO3

For hyperkalemia:
We use Sodium bicarbonate IV- (alkalosis caused by this drives K into cells)
