Sodium Bicarb - Action (2)

A
  • binds w/ Hydrogen ions to form H2O and CO2 with CO2 excreted by lungs, decreasing the acidity of blood- cause potassium (k) to shift into cells

Q

Sodium Bicarb - Side Effects (5)

A
  • paradoxical intracellular/tissue acidosis due to Co2 generation & inadequate ventilation to rid CO2 which readily diffuses across cell membranes- hypernatremia from large sodium load- hyperosmolarity from large sodium load- may shift O2 curve to left which causes a decrease in release of O2 by hgb to tissues- metabolic alkalosis

Q

Sodium Bicarb - Precautions (4)

A
  • give based on ABG values- bicarb therapy should be considered only after defib, CPR, ETT/vent, trial of epinephrine- overly aggressive field use may result in metabolic alkalosis- do not mix with CaCh precipates in line
